Found these on iTunesU from La Trobe University (Australia) – interviews with John Biggs (constructive alignment and problem based learning); Vaughan Prain (teaching science); Chris Scanlan (New media for journalism students); Lorraine Ling (future of education). Nice, listenable, relatively short podcast interviews.
Link to Biggs interview is here – this will open iTunes and the others are there [would like a nice iTunes embedder…?]
