I developed the following concept map for our reading and discussion on conceptual change this semester. The bottom half of the map (in blue) is targeted at the key idea of what is conceptual change. Above (in pink) is targeted at the other key idea of how can we facilitate change. A major theme was the importance of prior knowledge. Additional factors include the influence of development and the fact that this is situated as seeking progress in the learner’s conceptualization towards an accepted model.
