Garrison, Anderson & Archer

Garrison, Anderson, and Archer are researchers who developed the SAM (Substitutes, Aggregates, and Modifiers) model, a framework to analyze teaching strategies. It helps educators understand how different instructional methods and tools can impact learning by examining if they serve as substitutes, complements, or modifiers of traditional teaching approaches. Essentially, it guides educators in designing effective learning experiences by considering how various elements work together to enhance understanding and engagement.
