Use a direct statement telling the student to start (rather than stop) a behavior;
Look directly at the student as you give the request, move close, and use a soft, calm voice.; speak clearly, slowly and concisely—do not shout.
Limit requests to only two or three at a time and give requests that the student is capable of following;
Allow enough time for the student to follow through; and
Recognize their effort with verbal praise and encouragement.
