Let’s face it: homework can be almost as frustrating (沮丧) for parents as it is for kids. Getting kids to do their homework can be a challenge, and when they do sit down to study, a lot of other problems can appear. Doing homework may not be as fun as playing video games or chatting with friends, but it shouldn’t be something that kids hate. Your children’s assignments (任务) should help them build a skill or learn something new. You can help by being a homework monitor, stepping in to answer questions or offer encouragement. This gives you a chance to see what they are learning and how well they understand the material. It helps you understand their learning style and shows you care about their education. Many kids refuse to study by asking why they have to learn things they’ll never use in real life. If your son or daughter shows little interest in their assignments, you can make them seem more important by pointing out ways you use them in daily life. If parents feel that their kids are overloaded (超负荷), they can talk about it with the teachers. If you think it takes your child too long to finish homework, try to make a decision whether the problem lies in having too much work or managing time poorly. If your child complains of boredom while doing homework, give him or her the following suggestions: Get help from friends: if your children are bored with an assignment, let them call a friend for help or invite a friend over to work on it with them. Add physical activity: set mini-goals for homework and allow time for relaxing, jumping around, or a snack after each goal is completed. For a kid who can’t sit still, find active ways to study. Turn the tables: let your children teach you a lesson. Let them give you a test on the things they have just learned.
