Choice theory states that students should have a say in how their classroom is run and what they learn. It focuses on building strong relationships between students and teachers. William Glasser developed choice theory and control theory, which explains that all behavior is a choice to meet basic psychological needs. Choice theory impacts classrooms by having students participate in rule-making and choosing curriculum and instructional methods. It advocates for non-coercive discipline through student-teacher contracts where students take responsibility for misbehavior and devise their own solutions.
