It is difficult for parents of nearly every family to teach their children to be responsible(有责任的)for
housework, but with one of the f
ollowing suggestions, you really can get your children to help at home.
If you give your children the impression that they can never do anything quite right, then they will regard
themselves as unfit or unable persons. Unless children believe they can succeed, they will never become
totally independent.
My daughter Mary'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 (掌握) and declared
firmly they could learn what they had missed.
You can use the same way when you evaluate(评价)your child's work at home. Don't always scold
and you should 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, promise him a Sunday trip or a ball game with Dad.
Learning is a process(过程)of trying and failing and tryin
g and succeeding. If you teach your children
not to fear a mistake of failure, they will learn faster and achieve success at last.
