Educational technology is the systematic application of knowledge of science and technology to education. It allows for a scientific approach to teaching and learning, helping students focus on various fields of knowledge. Teaching aids are devices or means used to stimulate learner interest and curiosity, helping them focus on the subject. They create a vivid impression to facilitate learning. Some key types of teaching aids include non-projected aids like graphs, projected aids like slides, audio aids like tapes, and audiovisual aids like videos. Guidelines for the effective use of teaching aids include using them to supplement rather than replace experiences, and moving from simple to complex concepts.
