This document discusses several learning theories and how teachers apply them in the classroom, including behavioral, cognitive, constructivist, and social cognitive theories. Behavioral theory views learning as a process of forming associations between stimuli and responses. Cognitive theory sees learning as a process of receiving, processing, and storing information. Constructivism describes learning as constructing knowledge from experiences. Social cognitive theory emphasizes learning through observing and modeling behaviors of others. The document provides examples of how teachers implement techniques from these theories in their lessons and classrooms.
