Again coming from the Sports Department at NLC (shared by Alex Bromley), the Review Wheel is an interactive PowerPoint which allows students to 'choose' their own way of reviewing a session. Including such options as 'tweet it', 'explain it', 'post it' and 'map it' (to name a few), this allows for a fun and engaging end to any session.
