This document discusses models of teaching, defining them as plans or guidelines that can be used to design instruction, curriculum, and guide teacher actions. It presents several definitions of teaching models from education researchers. The main characteristics of models include specifying learning outcomes, environmental conditions, and performance criteria. Models of teaching are based on systematically modifying learner behavior. They can help teachers select methods and materials, bring about learner behavior changes, and design educational activities and curriculum. Examples of modern models discussed are information processing, social interaction, personal development, and behavior modification models.
