Which of the following techniques is least effective for managing behaviors in classrooms?

Ignoring negative behaviors can be considered the least effective technique for managing behaviors in classrooms. This approach may inadvertently reinforce the undesirable behaviors, as the student may perceive a lack of response as a form of attention or validation. While there may be situations in which ignoring a behavior can be beneficial, especially if the intent is to not reward it with attention, it does not actively teach or guide the student towards more appropriate behaviors.

In contrast, positive reinforcement encourages and strengthens desired behaviors by providing rewards or recognition, thereby fostering a more positive learning environment. Modeling appropriate behavior demonstrates to students what they should do instead, providing a clear example for them to follow. Setting clear expectations creates a structured environment where students understand what is expected of them, which can help reduce confusion and misbehavior. These techniques are proactive and focus on promoting good behavior, which tends to lead to more effective classroom management.
