Give immediate feedback when student behavior is inappropriate. Be firm but not overly punitive.

Allow a few moments for students to talk, such as at the beginning or end of class.

Encourage small group activities so that students can have fun while discussing important topics.

Use a variety of activities to keep students engaged and interested.

Monitor student behavior closely and address misbehavior quickly.

Make sure that your instructions are clear and not too complex.

Finally, remain calm and consistent.
