My daughter Carla’s fifth-grade teacher made every child in her class feel special. When students received less than a perfect test score, she would point out what they had mastered and declared firmly they could learn what they had missed.

You can use the same technique when you evaluate （评价）your child’s work at home. Don’t always scold and give lots of praise instead. Talk about what he has done right, not about what he hasn’t done. If your child completes a difficult task, reward him with a Sunday trip or a ball game with Dad.

Learning is a process （过程）of trying and failing and trying and succeeding. If you teach your children not to fear a mistake of failure, they will learn faster and achieve success at last.
