My own reflections on MICER17:
Two related themes emerged for me from the Methods in Chemistry Education Research meeting last week: confidence and iteration.
Let’s start where we finished: Georgios Tsaparlis’ presentation gave an overview of his career studying problem solving. This work emerged out of Johnstone’s remarkable findings around working memory and mental demand (M-demand).1,2 Johnstone devised a simple formula – if the requirements of a task were within the capability of working memory, students would be able to process the task; if not, students would find it difficult. This proposal was borne out of the plots of performance against complexity (demand) which showed a substantial drop at the point where M-demand exceeded working memory, and these findings seeded a remarkable amount of subsequent research.
