This document discusses models of teaching and provides an overview of Robert Glaser's basic teaching model. It defines what a teaching model is and lists its key characteristics. A teaching model is a plan or pattern that can help improve instructional effectiveness. All good models specify learning outcomes, environmental conditions, and performance criteria. Glaser's basic teaching model divides the teaching process into four main components: focus, syntax, social system, and principles of reaction. It provides a simplified framework for conceptualizing the teaching and learning process.
