Can a Teacher Truly Motivate a Student?

Homework is constantly turned in late. No homework is turned in at all. Mike takes 9 wks to get in an assignment. Johnny brings no pencil to Mathematics class. Belinda does not bring paper nor pen to Language Arts class. Jimmy never dresses out for PE. Billy says "they're not gonna fail me anyway!" Amy says "I will just go to Summer School." I am sure as a teacher you have heard it all before. I am sure you have heard it over and over again. I am also sure your principal has said "You have to motivate Johnny" or "what are you going to do to motivate Jimmy?" Teachers are expected to do alot day after day after day. The teacher can pull Johnny to the side and tell him how the situation looks and what's the best fit for him. He/she can guide him but the teacher doesn't go home with the student. Yes, the teacher spends much time with the student; however, the teacher is NOT the parent. What applies in the classroom may not apply at home. If you know like I know, the child will tell you that, as well. Is it helping the student to provide supplies for him/her constantly? Is it helping the student to allow him to turn in assignments late constantly? How is a teacher supposed to motivate a student that really doesn't like school or just is not motivated to be there because of their surroundings. The pressure is on for the teacher who wants the student to excel yet feels the pressure from Administration. It's alot to deal with from a teacher's standpoint! How do you feel? Talk back to me if you can!
