This will help get the student's mind back on task. Help students develop decision making skills by giving them simple decision to make during the day. For instance, they can take their test in ink or pencil. Explain your decisions to the students and encourage them to do the same for you. Allow students to do constructive doodling.
Some students are more attentive when doodling.
Sincerely praise students often for specific things they have done during the day. Encourage participation in all activities. Shift the focus away from winning or losing to enjoyment, contribution and satisfaction. Post rules for your class. Be sure to put what you want students to do, not what you don't want them to do.
