Research shows that students benefit from active learning strategies in the classroom. In this session we request proposals for demonstrations of successful activities that attendees could use in their own teaching. Demonstrations should be active, i.e., the audience members should be called on to participate in them, or a video should be shown of students performing the activity. Demonstrations should take no more than 13 minutes and be accompanied by a handout outlining the activity for participants to take home. Each demonstrator will have 2 minutes at the start of the session to introduce their activity, the grade/educational level it is aimed at and the learning context that their activity fits into. Demonstrators will then simultaneously present through the rest of the session in a share-a-thon format, with attendees free to move between tables/activities. We ask that abstracts briefly outline the activity and learning objective, educational level the activity is aimed at, and any requests for demonstration space (e.g. video screen, table, large open space).
