As a parent have you ever yelled at your children to get them to do homework, have you tried to "help" them by fighting your way through masses of mass-produced worksheet and have you ever wondered if there was a point ? Did you give up a trip, a walk, reading, talking with your kids because they have homework?
As a teacher have you ever had a great lesson with your students and watch the joy go away and heard the moans as soon as you mention the word "homework"?
If the answer is yes then this is the book to read. Parents and teachers know it and Alfie Kohn proves it : homework is useless. Fight it , replace it with home learning and spend time with your kids doing what you and they like. It will "teach them" more thing than another worksheet.
