Video as an assessment tool

On my class website, I plan to include video from class related to fitness, skill development, strategies and tactics from sport units.  These videos help students prepare for in-class video analysis (a Video Exam), to assess their learning of specific content in Physical Education.  If we are considering technique of the bench press, critical elements for hurdling in track, or the overhead clear and smash shots in badminton... video provides visual scaffolding, but also very importantly a means to assess student learning.
