Behavior is a fundamental aspect of human interaction, particularly in educational settings where understanding it can transform classroom dynamics. At its core, behavior is defined as anything a person does that can be observed. This includes actions as varied as speaking, writing, walking, or even sitting silently. In a classroom, behaviors range from a student raising their hand to answer a question to more challenging actions like calling out or refusing to complete work. Recognizing that every behavior serves a purpose is the first step toward addressing it effectively.
