Consider Collaboration
When using cases to complete a complex assignment, first model this in the classroom as a discussion. View the videos together and point out salient points as they occur in the videos.
Next, use the same assignment / learning activity with a new case that is given to small groups. Videos can be watched by learners out of class, then they can meet (in or out of class) to discuss the assignment. This will give learners confidence in their ability to interpret the case and describe or defend their critical reflection to others in the group. Provide feedback to each group related to the assignment and learning objectives.
Finally, use the same assignment / learning activity with a new case, given to individual learners to complete. This will transfer the responsibility of learning and critical reflection to each learner.
