This document discusses teaching aids and their classification and purposes. It defines teaching aids as devices used to present concepts to students to help learning in an attractive and effective way. Teaching aids are classified as projected aids, non-projected aids, and activity aids. Projected aids like films and slides are displayed on a screen using mechanical devices and stimulate self-activity. Non-projected aids do not require projections and include graphic aids, display boards, 3D aids, and audio aids. Activity aids involve student participation through hands-on experiences like field trips, exhibitions, and demonstrations. The document emphasizes that teaching aids make learning easier and more engaging while developing students' skills.
