This document summarizes several theories of classroom management: 1) Choice Theory by William Glasser focuses on satisfying student needs for belonging, power, freedom and fun to encourage self-control. Teachers create a kind environment and guide student interests. 2) Student-Directed Learning by Alfie Kohn takes a constructivist approach where students participate in classroom decisions through real choices and class meetings. 3) Behavior Management Theory by B.F. Skinner uses reinforcement of positive behaviors through compliments and praise to reshape student actions. It also discusses Assertive Discipline by Lee Canter which clearly structures the classroom environment and consequences to create a safe and organized learning space.
