Links to Back Issues of University Chemistry Education

I don’t know if I am missing something, but I have found it hard to locate past issues of University Chemistry Education, the predecessor to CERP.  They are not linked on the RSC journal page. CERP arose out of a merger between U Chem Ed and CERAPIE, and it is the CERAPIE articles that are hosted in the CERP back issues. Confused? Yes. (More on all of this here)

Anyway in searching and hunting old U Chem Ed articles, I have cracked the code of links and compiled links to back issues below. They are full of goodness. (The very last article published in UCE was the very first chemistry education paper I read – David McGarvey’s “Experimenting with Undergraduate Practicals“.)

Dialogue in lectures

This is not a post on whether the lecture is A Good Thing or not. Lectures happen. PERIOD!

A paper by Anna Wood and colleagues at the Edinburgh PER group, along with a subsequent talk by Anna at Moray House has gotten me thinking a lot over the last year about dialogue and its place in all of our interactions with students. The literature on feedback is replete with discussion on dialogue, sensibly so. The feedback cycle could be considered (simplistically) as a conversation: the student says something to the teacher in their work; the teacher says something back to the student in their feedback. There’s some conversation going on. Feedback literature talks about how this conversation continues, but what about the bit before this conversation begins?

Not a monologue

The spark from Wood’s work for me was that lectures are not a monologue. She is considering active lectures in particular, but cites Bamford* who gives a lovely overview of the nature of conversation in lectures in general. Bamford presents the case the lectures are not a monologue, but are a conversation. Just as in the feedback example above, two people are conversing with each other, although not verbally. In a lecturer, the lecturer might ask: “Is that OK?”. An individual student might respond inwardly “Yes, I am getting this” or “No, I haven’t a freaking clue what is going on and when is coffee”. A dialogue happened. Wood’s paper discusses these vicarious interactions – a delicious phrase describing the process of having both sides of the conversation; an internal dialogue of sorts. She describes how this dialogue continues in active lectures, but sadly there is only one Ross Galloway, so let’s think about how this conversation might continue in lectures given by us mere mortals. How can we help and inform these vicarious interactions?

Developing a conversation

A problem you will by now have identified is that the conversation: “Is that OK?” and retort isn’t much of a conversation. So how can we continue this conversation? My intention is to consider conversation starters in lectures that foster a sense with each individual student that they are having a personal conversation with the lecturer at points during the lecture. And incorporates guides for the student to continue this conversation after the lecture, up to the point that they submit their work, prompting the conversation we started with above.

In Woods talk, she mentioned specific examples. The lecturer would ask something like: “Is 7 J a reasonable answer?” A problem with “Is that OK?” is that it is too broad. It’s difficult to follow up the conversation specifically as it likely ends with yes or no.

How about a lecturer asks: “Why is this smaller than…?” You’re a student, and you’re listening. Why is it smaller? Do you know? Yes? No? Is it because…? Regardless of your answer, you are waiting for the response. You think you know the answer, or you know you don’t.

If we are to take dialogue seriously, then the crucial bit is what happens next. Eric Mazur will rightly tell us that we should have allow discussion with peers about this, but we are mortals, and want to get on with the lecture. So how about the conversation goes something like this:

“Why is this smaller than…?”


You are a student: you will have an answer: You know, you think you know, you don’t know, you don’t know what’s going on. You will have some response.

The lecturer continues:

“For those of you who think…”

The lecturer responds with a couple of scenarios. The conversation continues beyond a couplet.

Did you think of one of these scenarios? If so the lecturer is talking to you. Yes I did think that and I have it confirmed now I am right. Or: yes I did think that, why is that wrong?

The lecturer can continue:

“While it makes sense to think that, have a look in reference XYZ for a bit more detail”.

The lecturer thus concludes this part of the conversation. A dialogue has happened and each student knows that that they have a good idea what is going on, they don’t but know where to follow up this issue, or that they haven’t a clue what is going on. Whichever case, there is some outcome, and some action prompted. Indeed one could argue that this prompted action (refer to reference) is a bridge between the lecture and tutorial – I checked this reference but don’t understand – and so the conversation continues there.

This all seems very obvious, and maybe everyone else does this and didn’t tell me. My lectures tend to have lots of “Is that OK?” type questions, but I do like this idea of a much more purposeful design to structuring the conversation with a large class. I should say that this is entirely without research base beyond what I have read, but I think it would be very empowering for students to think that a lecturer is aiming to have a conversation with them.


*Bamford is cited in Wood’s paper and I got most of it on Google Books.

Revising functional groups with lightbulb feedback

I’m always a little envious when people tell me they were students of chemistry at Glasgow during Alex Johnstone’s time there. A recent read from the Education in Chemistry back-catalogue has turned me a shade greener. Let me tell you about something wonderful.

The concept of working memory is based on the notion that we can process a finite number of new bits in one instance, originally thought to be about 7, now about 4.  What these ‘bits’ are depend on what we know. So a person who only knows a little chemistry will look at a complex organic molecule and see lots of carbons, hydrogens, etc joined together. Remembering it (or even discussing its structure/reactivity) would be very difficult – there are too many bits. A more advanced learner may be able to identify functional groups, where a group is an assembly or atoms in a particular pattern; ketones for example being an assembly of three carbons and an oxygen, with particular bonding arrangements. This reduces the number of bits.

Functional groups are important for organic chemists as they will determine the reactivity of the molecule, and a challenge for novices to be able to do this is to first be able to identify the functional groups. In order to help students practise this, Johnstone developed an innovative approach (this was 1982): an electronic circuit board.

Functional Group Board: Black dots represent points were students needed to wire from name to example of functional group
Functional Group Board: Black dots represent points were students needed to wire from name to example of functional group

The board was designed so that it was covered with a piece of paper listing all functional groups of interest on either side, and then an array of molecules in the middle, with functional groups circled. Students were asked to connect a lead from the functional group name to a matching functional group, and if they were correct, a lightbulb would flash.

A lightbulb would flash. Can you imagine the joy?!

Amide backup card
Amide backup card

If not, “back-up cards” were available so that students could review any that they connected incorrectly, and were then directed back to the board.

The board was made available to students in laboratory sessions, and they were just directed to play with it in groups to stimulate discussion (and so as “not to frighten them away with yet another test”). Thus students were able to test out their knowledge, and if incorrect they had resources to review and re-test. Needless to say the board was very popular with students, such that more complex sheets were developed for medical students.

Because this is 1982 and pre-… well, everything, Johnstone offers instructions for building the board, developed with the departmental electrician. Circuit instructions for 50 x 60 cm board were given, along with details of mounting various plans of functional groups onto the pegboard for assembly. I want one!

What is the purpose of practical work?

I have been reading quite a lot about why we do practical work. Laboratory work is a core component of the chemistry (science) curriculum but its ubiquity means that we rarely stop to consider its purpose explicitly. This leads to many problems. An interesting quote summarises one:

One of the interesting things about laboratories is that there has never been definite consensus about those serious purposes. Perhaps that is why they have remained popular: they can be thought to support almost any aim of teaching.1

Even within institutions, where their might be some prescription of what the purpose is in broad terms, different faculty involved in the laboratory may have different emphases, and subsequently the message about what the purpose of practical work is differs depending on who is running the lab on a given day.2

This matters for various reasons. The first is that if there is confusion about the purpose of practical work, then everyone involved will place their attention onto the part that they think is most important. Academics will likely consider overarching goals, with students developing scientific skills and nature of science aspects.3 Demonstrators will think about teaching how to use instruments or complete techniques. Students will follow the money, and focus on the assessment, usually the lab report, which means their time is best utilised by getting the results as quickly as possible and getting out of the lab.4 Everybody’s priority is different because the purposes were never made clear. As in crystalline.

The second reason that thinking about purposes is that without an explicit consideration of what the purposes of practical work are, it is difficult to challenge these purposes, and consider their value. How many lab manuals open up with a line similar to: “The purpose of these practicals is to reaffirm theory taught in lectures…”? The notion that the purpose of practicals is in somehow supplementing taught material in lectures has long come in for criticism, and has little basis in evidence. Laboratories are generally quite inefficient places to “teach” theory. Woolnough and Allsop argued vehemently for cutting the “Gordian Knot” between theory and practical, arguing that practical settings offered their own unique purpose that, rather than being subservient to theory work, complemented it.5 Kirchner picks this argument up, describing science education in terms of substantive structure and syntactical structure. The former deals with the knowledge base of science, the latter with the acts of how we do science.6 Anderson had earlier distinguished between “science” and “sciencing”.

Discussion therefore needs to focus on what this syntactical structure is – what is “sciencing”? Here, the literature is vast, and often contradictory. To make a start, we look to Johnstone who, with his usual pragmatism, distinguished between aims of practical work (what we set out to do) and objectives of practical work (what the students achieve).8 With this in mind, we can begin to have some serious discussion about what we want practical work to achieve in our curricula.

Why do academics use technology in teaching?

This week is All Aboard week in Ireland, essayed at “Building Confidence in Digital Skills for Learning”. I am speaking today in the gorgeous city of Galway on this topic, and came across this paper in a recent BJET which gives some useful context. It summarises interviews with 33 Australian academics from various disciplines, on the topic of why they used technology in assessment. While the particular lens is on assessment, I think there are some useful things to note for those espousing the incorporation of technology generally.

Four themes emerge from the interviews

The first is that there is a perceived cost-benefit analysis at play; the cost of establishing an assessment process (e.g. quizzes) was perceived to be offset by the benefit that it would offer, such as reducing workload in the long-run. However, some responses suggest that this economic bet didn’t pay off, and that lack of time meant that academics often took quick solutions or those they knew about, such as multiple choice quizzes.

The second theme is that technology was adopted because it is considered contemporary and innovative; this suggests a sense of inevitability of using tools as they are there. A (mildly upsetting) quote from an interview is given:

“It would have been nice if we could have brainstormed what we wanted students to achieve, rather than just saying “well how can ICT be integrated within a subject?”

The third theme was one around the intention to shape students’ behaviour – providing activities to guide them through learning. There was a sense that this was expected and welcomed by students.

Finally, at the point of implementation, significant support was required, which often wasn’t forthcoming, and because of this, and other factors, intentions had to be compromised.

The authors use these themes to make some points about the process of advocating and supporting those integrating technology. I like their point about “formative development” – rolling out things over multiple iterations and thus lowering the stakes. Certainly my own experience (in hindsight!) reflects the benefit of this.

One other aspect of advocacy that isn’t mentioned but I think could be is to provide a framework upon which you hang your approaches. Giving students quizzes “coz it helps them revise” probably isn’t a sufficient framework, and nor is “lecture capture coz we can”. I try to use the framework of cognitive load theory as a basis for a lot of what I do, so that I have some justification for when things are supported or not, depending on where I expect students to be at in their progression. It’s a tricky balance, but I think such a framework at least prompts consideration of an overall approach rather than a piecemeal one.

There’s a lovely graphic from All Aboard showing lots of technologies, and as an awareness tool it is great. But there is probably a huge amount to be done in terms of digital literacy, regarding both the how, but also the why, of integrating technology into our teaching approaches.

Video: e-portfolios for documenting learning in the 21st century

Here is a talk I gave to school teachers at an NCCA event in Dublin Castle earlier this year. It discusses:

  1. Why and how we should enable students create digital artefacts to document their learning?
  2. Practical approaches to doing this – discussing digital badges and wikis in particular.

#ViCEPHEC16 – curly arrows and labs

The annual Variety in Chemistry Education/Physics Higher Education conference was on this week in Southampton. Some notes and thoughts are below.

Curly arrows

Physicists learned a lot about curly arrows at this conference. Nick Greeves‘ opening keynote spoke about the development of ChemTube3D – a stunning achievement – over 1000 HTML pages, mostly developed by UG students. News for those who know the site are that 3D curly arrow mechanisms are now part of the reaction mechanism visualisations, really beautiful visualisation of changing orbitals as a reaction proceeds for 30+ reactions, lovely visualisations of MOFs, direct links to/from various textbooks, and an app at the prototype stage. Nick explained that this has all been developed with small amounts of money from various agencies, including the HEA Physical Sciences Centre.

Mike Casey from UCD spoke about a resource at a much earlier stage of development; an interactive mechanism tutor. Students can choose a reaction type and then answer the question by drawing the mechanism – based on their answer they receive feedback. Version 2 is on the way with improved feedback, but I wondered if this feedback might include a link to the appropriate place in Chemtube3D, so that students could watch the associated visualisation as part of the feedback.

In the same session Robert Campbell spoke about his research on how A-level students answer organic chemistry questions. My understanding is that students tend to use rules of mechanisms (e.g. primary alkyl halides means it’s always SN2) without understanding the reason why; hence promoting rote learning. In a nice project situated in the context of cognitive load theory, Rob used Livescribe technology to investigate students reasoning. Looking forward to seeing this research in print.

Rob’s future work alluded to considering the video worked answers described by Stephen Barnes, also for A-level students. These demonstrated a simple but clever approach; using questions resembling A-level standard, asking students to complete them, providing video worked examples so students could self-assess, and then getting them to reflect on how they can improve. David Read mentioned that this model aligned with the work of Sadler, worth a read.

Laboratory work

Selfishly, I was really happy to see lots of talks about labs on the programme. Ian Bearden was the physics keynote, and he spoke about opening the laboratory course – meaning the removal of prescriptive and allowing students to develop their own procedures. Moving away from pure recipe is of course music to this audience’s ears and the talk was very well received. But you can’t please everyone – I would have loved to hear much more about what was done and the data involved, rather than the opening half of the talk about the rationale for doing so. A short discussion prompted this tweet from Felix Janeway, something we can agree on! But I will definitely be exploring this work more. Ian also mentioned that this approach is also part of physics modules taught to trainee teachers, which sounded a very good idea.

Jennifer Evans spoke about the prevalence of pre-labs in UK institutions following on from the Carnduff and Reid study in 2003. Surprisingly many don’t have any form of pre-lab work. It will be interesting to get a sense of what pre-lab work involves – is it theory or practice? Theory and practice were mentioned in a study from Oxford presented by Ruiqi Yu, an undergraduate student. This showed mixed messages on the purpose of practical work, surely something the academy need to agree on once and for all. There was also quite a nice poster from Oxford involving a simulation designed to teach experimental design, accessible at this link. This was also built by an undergraduate student. Cate Cropper from Liverpool gave a really useful talk on tablets in labs – exploring the nitty gritty of how they might work. Finally on labs, Jenny Slaughter gave an overview of the Bristol ChemLabs, which is neatly summarised in this EiC article, although the link to the HEA document has broken.

Other bites

  • Gwen Lawrie (via Skype) and Glenn Hurst spoke about professional development; Gwen mentioned this site she has developed with Madeline Schultz and others to inform lecturers about PCK. Glenn spoke about a lovely project on training PhD students for laboratory teaching – details here.  This reminds me of Barry Ryan‘s work at DIT.
  • Kristy Turner gave an overview of the School Teacher Fellow model at Manchester, allowing her to work both at school and university with obvious benefits for both. Kristy looked forward to an army of Kristy’s, which would indeed be formidable, albeit quite scary. Even without that, the conference undoubtedly benefits from the presence of school teachers, as Rob’s talk, mentioned above, demonstrates.
  • Rachel Koramoah gave a really great workshop on qualitative data analysis. Proving the interest in chemistry education research, this workshop filled up quickly. The post-it note method was demonstrated, which was interesting and will certainly explore more, but I hope to tease out a bit more detail on the data reduction step. This is the benefit of this model – the participants reduce the data for you – but I worry that this might in turn lead to loss of valuable data.
  • Matthew Mears gave a great byte on the value of explicit signposting to textbooks using the R-D-L approach: Read (assign a reading); Do (Assign questions to try); Learn (assign questions to confirm understanding). Matt said setting it up takes about 30 minutes and he has seen marked improvements in student performance in comparison to other sections of the course.
  • David Nutt won the best poster prize. His poster showed the results of eye-tracking experiments to demonstrate the value or not of an in-screen presenter. Very interesting results which I look forward to seeing in print.

The conference organisation was brilliant and thanks to Paul Duckmanton and Charles (Minion) Harrison for leading the organisation. Lots of happy but tired punters left on Friday afternoon.

I couldn’t attend everything, and other perspectives on the meeting with links etc can be found at links below. From Twitter, Barry Ryan’s presenation on NearPod seemed popular, along with the continuing amazingness of my colleagues in the Edinburgh Physics Education Research Group. One of their talks, by Anna Wood, is available online.

Getting ready to badge and looking for interested partners

Over the summer we have been working on a lab skills badging project. Lots of detail is on the project home site, but briefly this is what it’s about:

  • Experimental skills are a crucial component of student laboratory learning, but we rarely assess them, or even check them, formally. For schools, there is a requirement to show that students are doing practical work.
  • By implementing a system whereby students review particular lab techniques in advance of labs, demonstrate them to a peer while being videod, reviews the technique with a peer using a checklist, and uploads the video for assessment, we intend that students will be able to learn and perform the technique to a high standard.
  • The video can form part of students electronic portfolio that they may wish to share in future (See this article for more on that).
  • The process is suitable for digital badging – awarding of an electronic badge acknowledging competency in a particular skill (think scout badges for… tying knots…).

Marcy Towns has a nice paper on this for pipetting and we are going to trial it for this and some other lab techniques.

Looking for interested parties to trial it out

I am looking for school teachers who would like to try this method out. It can be used to document any lab technique or procedure you like. You don’t necessarily need an exemplar video, but a core requirement is that you want to document students laboratory work formally, and acknowledge achievement in this work by a digital badge. We will provide the means to offer the badge, and exemplar videos if you need them, assuming they are within our stock. Interested teachers will be responsible for local implementation and assessment of quality (i.e. making the call on whether a badge is issued).

Yes I need help with badge design
Yes I need help with badge design

This will be part of a larger project and there will be some research on the value and impact of the digital badges, drawing from implementation case studies. This will be discussed with individuals, depending on their own local circumstances.

So if you are interested, let’s badge! You can contact me at: to follow up.

What is the “education literature”?

Over on the Education in Chemistry blog, Paul MacLellan wrote an excellent article on reasons teachers don’t engage with education research, which is well worth a read. Speaking a few years ago, I used analogy of a paddle boat steamer when talking about the penetration of education research in HE. The paddles throw up some splashes as it sails over the vast quantity of water below. These splashes were meant to represent how many engage with research – taking on what they hear on the grapevine, Twitter, or CPD. It isn’t systematic.

I’ve spent a lot of time wondering about whether I should expect my colleagues to read education research, and on balance, I don’t think I should. The reason stems from the argument made about different audiences by Keith Taber in MacLellan’s article, and quantified by the featured commenter under his post. And I think we need some clarity about what we mean by education research literature.

Primary, secondary, and tertiary literature

New research in any field is iterative. We know a certain amount, and someone does some research to add a little more to our understanding. In publishing these research findings, we tend to summarise what was known before to situate the work in context, and add on the new bit. As Taber points out, education has the unique position of aiming to address two audiences: like any field it is addressing other education researchers in that field; but also has a second audience; practitioners who may wish to change some aspect of their teaching, and are looking for “what works”. The trouble with the mixed audience is that the language and semantics for each are very different, leaving the practitioner feeling very frustrated. The featured comment under MacLellan’s blog documents this very well. The practitioner looking to improve faces the difficult challenge: they use some search engine with decent keywords and have to try to pick out some paper that will offer them nuggets. It really is a needle in a haystack, (or a splash of water from the river boat…).

If asked for advice, I think I would rather suggest that such practitioners would instead refer to secondary or tertiary literature. Secondary literature aims to summarise the research findings in a particular field. While it is still written with an audience of researchers from the field in mind, these reviews typically group the results from several individual studies into themes or overarching concepts, which can be useful to practitioners who may wish to see “what might work” in their own context. I recall the value of MacArthur and Jones’ review on clickers, and my own review of flipping lectures in chemistry are examples of this type.

The audience shifts more fully when we move to tertiary literature. While there is still likely two audiences for education research, the emphasis with tertiary literature is addressing a wider audience; introducing the field to a wider audience of interested readers. Typically books summarising teaching approaches are grounded in well documented research, but unlike secondary sources, they are written for those wishing to find out about the topic from an introductory level, and the language is considerate of the wider audience. Think of Taber’s books on misconceptions, and the impact they have had. More recently, the web has offered us new forms of tertiary literature – blogs are becoming more popular to disseminate the usefulness of research to a wider audience and summaries such that recently published by Tina Overton on factors to consider in teaching approaches can help introduce overarching research findings, without having to penetrate the original education research studies.

So should my colleagues read education research? I still don’t think so. A tourist to a new city wouldn’t read academic articles on transport infrastructure and architecture – they would just read the tourist guide. Of course it can be inspiring to read a case study or see what students in an individual situation experienced. But I would rather recommend secondary and tertiary sources to them if they are going to spend any valuable time reading.

And that means, in chemistry education’s case, we need a lot more of these types of publications. A recent J Chem Ed editorial suggested that they are thinking about promoting this type of publication, and any movement in that direction is welcome.

Planning a new book on laboratory education

Contracts have been signed so I am happy to say that I am writing a book on chemistry laboratory education as part of the RSC’s new Advances in Chemistry Education series due for publication mid 2017.

I’ve long had an interest in lab education, since stumbling across David McGarvey’s “Experimenting with Undergraduate Practicals” in University Chemistry Education (now CERP). Soon after, I met Stuart Bennett, now retired, from Open University at a European summer school. Stuart spoke about lab education and its potential affordances in the curriculum. He was an enormous influence on my thinking in chemistry education, and in practical work in particular. We’d later co-author a chapter on lab education for a book for new lecturers in chemistry published by the RSC (itself a good example on the benefits of European collaboration). My first piece of published education research was based on laboratory work; a report in CERP on the implementation of mini-projects in chemistry curriculum, completed with good friends and colleagues Claire Mc Donnell and Christine O’Connor. So I’ve been thinking about laboratory work for a long time.

Why a book?

A question I will likely be asking with increasing despair over the coming months is: why am I writing a book? To reaffirm to myself as much as anything else, and to remind me if I get lost on the way, the reasons are pretty straightforward.

My career decisions and personal interests over the last few years have meant that I have moved my focus entirely to chemistry education. Initially this involved sneaking in some reading between the covers of J. Mat. Chem. when I was meant to be catching up on metal oxide photocatalysis. But as time went on and thanks to the support of others involved in chemistry education, this interest became stronger. I eventually decided to make a break with chemistry and move into chemistry education research. (One of the nicest things for me personally about joining Edinburgh was that this interest was ultimately validated.)

So while my knowledge of latest chemistry research is limited mainly to Chemistry World reports, one thing I do know well is the chemistry education research literature. And there is a lot of literature on laboratory education. But as I read it and try to keep on top of it, it is apparent that much of the literature on laboratory education falls into themes, and by a bit of rethinking of these themes and by taking a curriculum design approach, some guiding principles for laboratory education can be drawn up. And that a compilation of such principles, within the context of offering a roadmap or plan for laboratory education might be useful to others.

And this is what I hope to offer. The book will be purposefully targeted at anyone responsible for taking a traditional university level chemistry laboratory course and looking to change it. In reality, such change is an enormous task, and being pragmatic, needs to happen in phases. It’s tempting then to tweak bits and change bits based on some innovation presented at a conference or seen in a paper. But there needs to be an overall design for the entire student experience, so that incremental changes sum up to an overall consistent whole piece. Furthermore, by offering a roadmap or overall design, I hope to empower members of staff who may be responsible for such change by giving the evidence they may need to rationalise changes to colleagues. Everyone has an opinion on laboratory education! The aim is to provide evidence-based design approaches.

My bookshelves are groaning with excellent books on laboratory education. I first came across Teaching in Laboratories by Boud Dunn and Hegarty-Hazel back in the days when I stumbled across McGarvey’s article. I still refer to it, as even though it was published in 1986, it still carries a lot of useful material. Woolnough and Allsop’s Practical Work in Science is also excellent; crystal clear on the role and value of laboratory education and its distinction from lecture based curriculum. Hegarty-Hazel also edited The Student Laboratory and the Science Curriculum. Roger Anderson’s book The Experience of Science was published before I was born.

I have bought these now out of print books and several more second hand for less than the cost of a cup of coffee. I have learned lots from them, but am mindful that (justifiably) well-known and comprehensive as they are, they are now out of print and our university laboratories have not seen much change in the forty years since Anderson.

I am very conscious of this as I structure my own book. I can speculate that books about science laboratories at both secondary and tertiary level may be too broad. So the book is focussing exclusively on chemistry and higher education.

Secondly, the book is very clearly directed at those implementing a new approach, those involved in change. Ultimately it is their drive and energy and input that decides the direction of changes that will occur.  I hope that by speaking directly to them with a clear rationale and approach based on an up-to-date literature, that it may ease the workload somewhat for those looking to rethink laboratory education in their curricula. Now I just need to actually write it.

Alex Johnstone’s 10 Educational Commandments

My thanks to Prof Tina Overton for alerting me to the fact that these exist. I subsequently happened across them in this article detailing an interview with Prof Johnstone (1), and thought they would be useful to share.

Ten Educational Commandments 

1. What is learned is controlled by what you already know and understand.

2. How you learn is controlled by how you learned in the past (related to learning style but also to your interpretation of the “rules”).

3. If learning is to be meaningful, it has to link on to existing knowledge and skills, enriching both (2).

4. The amount of material to be processed in unit time is limited (3).

5. Feedback and reassurance are necessary for comfortable learning, and assessment should be humane.

6. Cognisance should be taken of learning styles and motivation.

7. Students should consolidate their learning by asking themselves about what goes on in their own heads— metacognition.

8. There should be room for problem solving in its fullest sense (4).

9. There should be room to create, defend, try out, hypothesise.

10. There should be opportunity given to teach (you don’t really learn until you teach) (5).

Johnstone told his interviewer that he didn’t claim any originality for the statements, which his students called the 10 educational commandments. Rather he merely brought together well known ideas from the literature. But, and importantly for this fan, Johnstone said that they have been built into his own research and practice, using them as “stars to steer by”.

Practical work: theory or practice?

Literature on laboratory education over the last four decades (and more, I’m sure) has a lot to say on the role of practical work in undergraduate curricula. Indeed Baird Lloyd (1992) surveys opinions on the role of practical work in North American General Chemistry syllabi over the course of the 20th century and opens with this delicious quote, apparently offered by a student in 1928 in a $10 competition:

Chemistry laboratory is so intimately connected with the science of chemistry, that, without experimentation, the true spirit of the science cannot possibly be acquired. 

I love this quote because it captures so nicely the sense that laboratory work is at the heart of chemistry teaching – its implicit role in the teaching of chemistry is unquestionable. And although it has been questioned a lot, repeatedly, over the following decades; not many today would advocate a chemistry syllabus that did not contain laboratory work.

I feel another aspect of our consideration of chemistry labs is often unchallenged, and needs to be. That is the notion that chemistry laboratories are in some way proving ground for what students come across in lectures. That they provide an opportunity for students to visualise and see for themselves what the teacher or lecturer was talking about. Or more laudably, to even “discover” for themselves by following a controlled experiment a particular relationship. Didn’t believe it in class that an acid and an alcohol make an ester? Well now you are in labs, you can prove it. Can’t imagine that vapour pressure increases with temperature? Then come on in – we have just the practical for you. Faraday said that he was never able to make a fact his own without seeing it. But then again, he was a great demonstrator.

A problem with this on an operational level, especially at university, and especially in the physical chemistry laboratory, is that is near impossible to schedule practicals so that they follow on from the introduction of theory in class. This leads to the annual complaint from students that they can’t do the practical because they haven’t done the theory. Your students are saying this, if you haven’t heard them, you need to tune your surveys.

It’s an entirely understandable sentiment from students because we situate practicals as a subsidiary of lectures. But this is a false relationship for a variety of reasons. The first is that if you accept a model whereby you teach students chemistry content in lectures, why is there a need to supplement this teaching with a re-teaching of a sub-set of topics, arbitrarily chosen based on the whim of a lab course organiser and the size of a department’s budget? Secondly, although we aim to re-teach, or hit home some major principle again in lab work, we don’t really assess that. We might grade students’ lab report and give feedback, but it is not relevant to them as they won’t need to know it again in that context. The lab report is done. And finally, the model completely undermines the true role of practical work and value it can offer the curriculum.

A different model

When we design lecture courses, we don’t really give much thought to the labs that will go with them. Lecture course content has evolved rapidly to keep up to date with new chemistry; lab development is much slower. So why not the other way around? Why not design lab courses independent of lectures? Lecture courses are one area of the curriculum to learn – typically the content of the curriculum; laboratory courses are another. And what might the role here be?

Woolnough and Allsop (1985), who make a clear and convincing argument for cutting the “Gordian knot” between theory and practice, instead advocate a syllabus that has three aims:

  1. developing practical skills and techniques.
  2. being a problem-solving chemist.
  3. getting a “feel for phenomena”.

The detail of how this can be done is the subject of their book, but involves a syllabus that has “exercises, investigations, and experiences”. To me these amount to the “process” of chemistry. On a general level, I think this approach is worth consideration as it has several impacts on teaching and learning in practice.

Impacts on teaching and learning

Cutting the link between theory and practice means that there is no longer a need to examine students’ understanding of chemistry concepts by proxy. Long introductions, much hated by students, which aim to get the student to understand the theory behind the topic at hand by rephrasing what is given to them in a lab manual, are obsolete. A properly designed syllabus removes the need for students to have had lectures in a particular topic before a lab course. Pre-lab questions can move away from being about random bits of theory and focus on the relationships in the experiment. There is no need for pointless post-lab questions that try to squeeze in a bit more theory.

Instead, students will need to approach the lab with some kind of model for what is happening. This does not need to be the actual equations they learn in lectures. Some thought means they may be able to draw on prior knowledge to inform that model. Of course, the practical will likely involve using some aspect of what they cover or will cover in lectures, but at the stage of doing the practical, it is the fundamental relationship they are considering and exploring. Approaching the lab with a model of a relationship (clearly I am in phys chem labs here!) and exploring that relationship is better reflecting the nature of science, and focussing students attention on the study in question. Group discussions and sharing data are more meaningful. Perhaps labs could even inform future lectures rather than rely on past ones! A final advantage is the reassertion of practical skills and techniques as a valuable aspect of laboratory work.

A key point here is that the laboratory content is appropriate for the level of the curriculum, just as it is when we design lectures. This approach is not advocating random discovery – quite the opposite. But free of the bond with associated lectures, there is scope to develop a much more coherent, independent, and more genuinely complementary laboratory course.

Developing practical skills in the chemistry laboratory

How do we prepare students for practical skills they conduct in the laboratory?

Practical skills involve psychomotor development, as they typically involve handling chemicals, glassware, and instrumentation. But how do we prepare students for this work, and do we give them enough time to develop these skills?

Farmer and Frazer analysed 126 school experiments (from the old O-level Nuffield syllabus) with a view to categorising practical skills and came up with some interesting results.[1] Acknowledging that some psychomotor tasks include a cognitive component (they give the example of manipulating the air-hole collar of a Bunsen burner while judging the nature of the flame for a particular task at hand) they identified 65 psychomotor tasks and 108 cognitive tasks from the experiments studied. Some of these psychomotor tasks are defined as having a key role, in that the success of the experiment is dependent on the successful completion of that task, reducing the number of psychomotor skills to 44. Many of these key tasks were required in only a few experiments, so the set was again reduced to number of frequent key tasks – those occurring in more than 10 experiments. The 14 frequent key tasks subsequently identified are described in their table below.

Data from Education in Chemistry (Ref 1)
Data from Education in Chemistry (Ref 1)

Thus of the 65 psychomotor skills listed, only 14 are defined as frequent key tasks, limiting the opportunities for pupils to develop the skills associated with completing them. Indeed this paper goes on to demonstrate that in an assessment of 100 pupils, there was very poor demonstration of ability in correctly completing the practical tasks, which they attribute to the design of the syllabus and the limited opportunity to do practical work.

This article prompts me to think again: how do we prepare students for the laboratory skills aspect of practical work? I think the most common approach is to demonstrate immediately in advance of the student completing the practical, explaining the technique or the apparatus and its operation. However, demonstration puts students in the mode of observer; they are watching someone else complete an activity, rather than conceptualising their own completion. It also relies on the quality of the demonstrator, and is subject to local hazards, such as time available, ability to see and hear the demonstration, and so on. Therefore, there may be benefit in shifting this demonstration to pre-lab, allowing students time to become accustomed to a technique and its nuances.

Such pre-labs need to be carefully designed, and actively distinguished from any pre-lab information focussing on theory, which has a separate purpose. At Edinburgh, two strategies are planned.

The first is on the development of core introductory laboratory skills: titrations involving pipetting and buretting; preparing standard solutions including using a balance; and setting up Quickfit glassware to complete a distillation. Pre-lab information is provided to students in the form of videos demonstrating each technique, with key steps in each procedure highlighted in the video. Students will be required to demonstrate each of the three procedures to their peers in the laboratory, while their peer uses the checklist to ensure that all aspects of the task were completed appropriately. The purpose here is to incorporate preparation, demonstration, and peer-review into the learning of core lab skills, as well as to set in mind early on in students’ university careers the correct approach and the appropriate glassware to use for basic laboratory techniques. The approach includes students’ videoing their peers as part of the review process using mobile phones; and the video recording will subsequently be used as evidence for issuing students with a digital badge for that technique (more on that at the project homepage).

The second approach is to develop the laboratory manual beyond its traditional textbook format to be an electronic laboratory manual, with pre-lab demonstrations included. More on that project to come soon.

In designing pre-lab activities for skills development, the aim is to move beyond “just demonstrating” and to get students thinking through the approaches they will take. The reason for this is guided by work done by Beasley in the late 1970s. Beasley drew from the literature of physical education to consider the development of psychomotor skills in chemistry. He studied the concept of mental practice as a technique to help students prepare for the laboratory.[2] Mental practice is based on the notion that physical activity requires mental thought, and thus mentally or introspectively rehearsing an activity prompts neural and muscular responses.[3]  Students were assigned to groups where they conducted no preparation, physical preparation, mental preparation, and both physical and mental preparation. They were tested before and after completing a lab on volumetric analysis. Beasley reported that students who students entering college from school were not proficient in completing volumetric analysis based on accuracy of their results. Furthermore, there was no significant difference in post-test scores of treatment students (which were all better than students who did no preparation), suggesting that mental preparation was as effective as physical preparation.

Reflections on #micer16

Several years ago at the Variety in Chemistry Education conference, there was a rather sombre after-dinner conversation on whether the meeting would continue on in subsequent years. Attendance numbers were low and the age profile was favouring the upper half of the bell-curve.

Last year at Variety I registered before the deadline and got, what I think was the last space, and worried about whether my abstract would be considered. The meeting was packed full of energetic participants interested in teaching from all over UK and Ireland, at various stages of their careers. A swell in numbers is of course expected from the merging with the Physics Higher Education Conference, but the combination of the two is definitely (from this chemist’s perspective) greater than the sum of its parts.

Participants at #micer16
Participants at #micer16

What happened in the mean time would be worthy of a PhD study. How did the fragile strings that were just holding people together in this disparate, struggling community, not snap, but instead strengthen to bring in many newcomers? A complex web of new connections has grown.  While I watched it happen I am not sure how it happened. I suspect it is a confluence of many factors: the efforts of the RSC at a time when chemistry was at a low-point. The determination of the regular attendees to keep supporting it, knowing its inherent value. The ongoing support of people like Stuart Bennett, Dave McGarvey, Stephen Breuer, Bill Byers, and others. And of course the endless energy of Tina Overton and the crew at the Physical Sciences Centre at Hull.

Whatever the process, we are very lucky to have a vibrant community of people willing to push and challenge and innovate in our teaching of chemistry. And that community is willing and is expected to play a vital role in the development of teaching approaches. This requires design and evaluation of these approaches; a consideration of how they work in our educational context. And this requires the knowledge of how to design these research studies and complete these evaluations. Readers will note that Variety now particularly welcome evidence-based approaches.

Most of us in this community are chemists, and the language of education research can be new, and difficult to navigate. Thus a meeting such as MICER held last week aimed to introduce and/or develop approaches in education research. The speakers were excellent, but having selected them I knew they would be! Participants left, from what I could see and saw on social media, energised and enthused about the summer ahead and possible projects.

But we will all return to our individual departments, with the rest of the job to do, and soon enthusiasm gives way to pragmatism, as other things get in the way. It can be difficult to continue to develop expertise and competence in chemistry education research without a focus. The community needs to continue to support itself, and seek support from elsewhere.

How might this happen?

Support from within the community can happen by contacting someone you met at a conference and asking them to be a “critical friend”. Claire Mc Donnell introduced me to this term  and indeed was my critical friend. This is someone whom you trust to talk about your work with, share ideas and approaches, read drafts of work. It is a mutual relationship, and I have found it extremely beneficial, both from the perspective of having someone sensible to talk to, but also from a metacognitive perspective. Talking it out makes me think about it more.

The community can organise informal and formal journal clubs. Is there a particular paper you liked – how did the authors complete a study and what did they draw from it? Why not discuss it with someone, or better still in the open?

Over the next while I am hoping to crystallise these ideas and continue the conversations on how we do chemistry education research. I very much hope you can join me and be an active participant; indeed a proactive participant. So that there is an independent platform, I have set up the website and welcome anyone interested in being involved to get in touch about how we might plan activities or even a series of activities. I hope to see you there.

Learning analytics is an emerging discipline considering the measurement, collection and analysis of data about student learning with a view to improving their learning experience. This project involves the design and development of a learning analytics system for chemistry so that students can continually monitor and reflect on their progress, with a view to actively improving their understanding throughout their studies. The project builds on work on using students’ prior chemistry learning to examine future performance (Chem. Ed. Res. Pract., 2009, 10, 227-232) and assessing the impact of learning resources on student performance (Brit. J. Ed. Tech., 2012, 43(4), 667–677).

The project is fully-funded for 36-months starting in September 2016, covering UK/EU tuition fees and an annual stipend at the EPSRC standard rate (in the region of £14,200 in academic year 2016-17).

Applications are sought from UK/EU candidates with an excellent track record in chemistry or chemistry education with an interest in higher education and the use of technology in education. Experience with e-learning software and statistical processing packages is desirable but not essential. Applicants must have or are expected to receive by the start date a 1st class or an upper 2nd class honours degree (or equivalent).

To apply, applicants should send the following to

  • A cover letter detailing interest in the position and any relevant experience.
  • A curriculum vitae.

The successful candidate will be required to apply through the EUCLID system as outlined at

Deadline: 1st Feb 2016

Date for #chemed diaries: Methods in Chemistry Education Research 20/5/16

Methods in Chemistry Education Research #micer16

Burlington House, 20th May 2016, 11 – 4 pm

This one day conference is being organised in response to a growing demand and interest in chemistry education research in the UK. The meeting will focus in particular on methods; the practicalities of how to do chemistry education research. Invited speakers with experience of completing and publishing discipline-based education research will give talks on particular methods, relating the methods to a theoretical framework, the research question, and discussing the practicalities of gathering data. Approaches to publication will be outlined. Each speaker will be followed by an extended structured discussion so that attendees have time to discuss further issues that arise. The meeting is being organised with the journal Chemistry Education Research and Practice which is free to access at the URL:

Attendance is free thanks to the support of the RSC’s Chemistry Education Research Group ( and Tertiary Education Group (

Session 1 (sponsored by the Chemistry Education Research Group)
In the first session, speakers will discuss their approach to education research with an emphasis on particular theoretical frameworks (e.g. grounded theory) and how this framework influences their method in addressing a research question.


Session 2 (sponsored by the Tertiary Education Group)
In the second session, speakers will discuss their approach with an emphasis on gathering data (e.g. focus groups), the reasons for these approaches in the context of the research question, and the considerations in interpreting this data.

Further information and a final list of speakers will be circulated early 2016.

Significant omission from my top 10 #chemed post!

0. Text messages to explore students’ study habits (Ye, Oueini, Dickerson, and Lewis, CERP)

I was excited to see Scott Lewis speak at the Conference That Shall Not Be Named during the summer as I really love his work. This paper outlines an interesting way to find out about student study habits, using text-message prompts. Students received periodic text messages asking them if they have studied in the past 48 hours. The method is ingenious. Results are discussed in terms of cluster analysis (didn’t study as much, used textbook/practiced problems, and online homework/reviewed notes). There is lots of good stuff here for those interested in students’ study and supporting independent study time. Lewis often publishes with Jennifer Lewis, and their papers are master-classes in quantitative data analysis. (Note this candidate for my top ten was so obvious I left it out in the original draft, so now it is a top 11…)

I’ve now included this in the original post.

My ten favourite #chemed articles of 2015

This post is a sure-fire way to lose friends… but I’m going to pick 10 papers that were published this year that I found interesting and/or useful. This is not to say they are ten of the best; everyone will have their own 10 “best” based on their own contexts.

Caveats done, here are 10 papers on chemistry education research that stood out for me this year:

0. Text messages to explore students’ study habits (Ye, Oueini, Dickerson, and Lewis, CERP)

I was excited to see Scott Lewis speak at the Conference That Shall Not Be Named during the summer as I really love his work. This paper outlines an interesting way to find out about student study habits, using text-message prompts. Students received periodic text messages asking them if they have studied in the past 48 hours. The method is ingenious.

Lewis often publishes with Jennifer Lewis, and together their papers are master-classes in quantitative data analysis. (Note this candidate for my top ten was so obvious I left it out in the original draft, so now it is a top 11…)

1. What do students learn in the laboratory (Galloway and Lowery-Bretz, CERP)?

This paper reports on an investigation using video cameras on the student to record their work in a chemistry lab. Students were interviewed soon after the lab. While we can see what students physically do while they are in the lab (psychomotor learning), it is harder to measure cognitive and affective experiences. This study set about trying to measure these, in the context of what the student considered to be meaningful learning. The paper is important for understanding learning that is going on in the laboratory (or not, in the case of recipe labs), but I liked it most for the use of video in collection of data.

2. Johnstone’s triangle in physical chemistry (Becker, Stanford, Towns, and Cole, CERP).

We are familiar with the importance of Johnstone’s triangle, but a lot of research often points to introductory chemistry, or the US “Gen Chem”. In this paper, consideration is given to understanding whether and how students relate macro, micro, and symbolic levels in thermodynamics, a subject that relies heavily on the symbolic (mathematical). The reliance on symbolic is probably due in no small part to the emphasis most textbooks place on this. The research looked at ways that classroom interactions can develop the translation across all levels, and most interestingly, a sequence of instructor interactions that showed an improvement in coordination of the three dimensions of triplet. There is a lot of good stuff for teachers of introductory thermodynamics here.

3. The all-seeing eye of prior knowledge (Boddey and de Berg, CERP).

My own interest in prior knowledge as a gauge for future learning means I greedily pick up anything that discusses it in further detail. And this paper does that well. It looked at the impact of completing a bridging course on students who had no previous chemistry, comparing them with those who had school chemistry. However, this study takes that typical analysis further, and interviewed students. These are used to tease out different levels of prior knowledge, with the ability to apply being supreme in improving exam performance.

4.  Flipped classes compared to active classes (Flynn, CERP).

I read a lot of papers on flipped lectures this year in preparing a review on the topic. This was by far the most comprehensive. Flipping is examined in small and large classes, and crucially any impact or improvement is discussed by comparing with an already active classroom. A detailed model for implementation of flipped lectures linking before, during, and after class activities is presented, and the whole piece is set in the context of curriculum design. This is dissemination of good practice at its best.

5. Defining problem solving strategies (Randles and Overton, CERP).

This paper gained a lot of attention at the time of publication, as it compares problem solving strategies of different groups in chemistry; undergraduates, academics, and industrialists. Beyond the headline though, I liked it particularly for its method – it is based on grounded theory, and the introductory sections give a very good overview on how this was achieved, which I think will be informative to many. Table 2 in particular demonstrates coding and example quotes which is very useful.

6. How do students experience labs? (Kable and more, IJSE)

This is a large scale project with a long gestation – the ultimate aim is to develop a laboratory experience survey, and in particular a survey for individual laboratory experiments, with a view to their iterative improvement. Three factors – motivation (interest and responsibility), assessment, and resources – are related to students’ positive experience of laboratory work. The survey probes students’ responses to these (some like quality of resources give surprising results). It is useful for anyone thinking about tweaking laboratory instruction, and looking for somewhere to start.

7. Approaches to learning and success in chemistry (Sinapuelas and Stacy, JRST)

Set in the context of transition from school to university, this work describes the categorisation of four levels of learning approaches (gathering facts, learning procedures, confirming understanding, applying ideas). I like these categories as they are a bit more nuanced, and perhaps less judgemental, than surface vs deep learning. The approach level correlates with exam performance. The paper discusses the use of learning resources to encourage students to move from learning procedures (level 2) to confirming understanding (level 3). There are in-depth descriptions characterising each level, and these will be informative to anyone thinking about how to support students’ independent study.

8. Exploring retention (Shedlosky-Shoemaker and Fautch, JCE).

This article categorises some psychological factors aiming to explain why some students do not complete their degree. Students switching degrees tend to have higher self-doubt (in general rather than just for chemistry) and performance anxiety. Motivation did not appear to distinguish between those switching or leaving a course and those staying. The study is useful for those interested in transition, as it challenges some common conceptions about student experiences and motivations. This study appears to suggest much more personal factors are at play.

9. Rethinking central ideas in chemistry (Talanquer, JCE).

Talanquer publishes regularly and operates on a different intellectual plane to most of us. While I can’t say I understand every argument he makes, he always provokes thought. In this commentary, he discusses the central ideas of introductory chemistry (atoms, elements, bonds, etc), and proposes alternative central ideas (chemical identity, mechanisms, etc). It’s one of a series of articles by several authors (including Talanquer himself) that continually challenge the approach we currently take to chemistry. It’s difficult to say whether this will ever become more than a thought experiment though…

10. Newcomers to education literature (Seethaler, JCE).

If you have ever wished to explain to a scientist colleague how education research “works”, this paper might be of use. It considers 5 things scientists should know about education research: what papers can tell you (and their limitations), theoretical bases in education research, a little on misconceptions and content inventories, describing learning, and tools of the trade. It’s a short article at three pages long, so necessarily leaves a lot of information out. But it is a nice primer.


The craziest graphical abstract of the year must go to Fung’s camera set up. And believe me, the competition was intense.

Inquiry learning of chemistry in 19th century girls schools

Consider the following scenario:

Young children are delighted to be so regarded, to be told that they are to act as a band of young detectives. For example, in studying the rusting of iron, they at once fall in with the idea that a crime, as it were, is committed when the valuable strong iron is changed into useless, brittle rust; with the greatest interest they set about finding out whether it is a case of murder or suicide, as it were−whether something outside the iron is concerned in the change or whether it changes of its own accord

The British chemist Henry Edward Armstrong pioneered the use of what is now called guided inquiry in the late nineteenth century. His story is recounted in articles by Rayner-Canham & Rayner-Canham (2011, 2014). Armstrong was a chemistry lecturer a St Barts and was frustrated at the emphasis of examinations on memorization and definitions. Over the decade from 1870, he developed the means for students to explore chemical concepts in the laboratory. Armstrong wrote of his approach:

For the ideal school of the future I picture the teacher no longer giving lessons but quietly moving about among the pupils, all earnestly at work and deeply interested, aiding each to accomplish the allotted task, as far as possible alone

His approach was called the heuristic approach, and it was structured such that it was carefully guided (In contrast with what we might call discovery learning today). While Armstrong himself was antagonistic against women in science, he promoted his method with girl’s schools science teachers from private schools. (Science in most girls schools didn’t feature until the 1950s.) One such teacher, Grace Heath from North London Collegiate for Girls, wrote to Nature in 1892:

…pupils themselves are put into the position of discoverers, they know why they are at work, what it is they want to discover, and as one experiment after another adds a new link to the chain of evidence which is solving their problem

This school had a laboratory with room for 24 girls at a time. Elsewhere St Swithun’s chemistry laboratory was built after girls left a flask of chlorine open deliberately during a tour by the administrative council in an aim to highlight the lack of facilities. We can learn lots from the past…

As the twentieth century progressed, a debate about the role of science education for girls and opposition from Sir William Ramsey and others to the heuristic method led to the rise of the lecture with demonstration method.
