Do not tape an hour long session showing Jason's day. If you are using a videotape as evidence it is best to tape a student at least once a grading period on the same task. State on the videotape anything specific that is important to the student's performance. He does not look at the choice cards nor respond to the activity selected. Remember you are capturing a student's performance on a particular day.
Students have good days and bad days.
This if fine. You are not taping only perfect performance. If a student has an unsuccessful attempt or is unable to perform a task on a particular day simply note that on the tape. Jason has needed help in controlling his outbursts today. If you videotape in different locations to show generalization of a skill, state on the tape the new location.
