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. 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 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.
