This leads to further predictions that have not yet been properly tested e.g. that learners will report these internalised activities when interviewed, and that study skill training would equip learners to perform such activities internally without further support. Nevertheless, I find this model to have real predictive power. That is, rather than studying the effects of media or of interactive modes on learning, I vote for studying these mathemagenic activities as primary factors determining learning. Laurillard's 12 mathemagenic activities Conceptual description Teacher describes the conception. Student re-expresses the conception.
Teacher redescribes the conception in the light of the student's expression or action.
Student redescribes the conception in the light of the teacher's redescription. Student acts to achieve the task goal. Teacher's world gives feedback on the action. Student modifies actions in the light of feedback. Student reflects on action to modify description.
