This document discusses various behavior modification techniques used in school settings, including modelling, shaping, contingency management, and behavioral contracting. Modelling involves a teacher demonstrating concepts for students to observe. Shaping is used to change undesirable behaviors by reinforcing successive approximations of the desired behavior. Contingency management uses reinforcement to increase positive behaviors and extinction or punishment to decrease negative behaviors. Behavioral contracting clearly outlines expectations and consequences to help monitor and change student behavior.
