Teachstone's CLASS Video Library is a collection of video recordings of live classroom sessions. The library is accessible by signing up in 12-month, six-month or one-month subscriptions through Teachstone's online store. Programs target different age ranges.
One of the main goals of the CLASS Video Library is to aid teachers in learning effective teaching and interactive techniques. The library's live classroom footage shows real teacher-student interaction and uses specific interactions as a springboard for discussing effective and ineffective techniques through the accompanying CLASS Dimensions Guide. The program reinforces concepts by having the teacher engage in program activities such as interaction and categorization.
