parents offer their school-age children money for each high grade (mark) they get in school I do not think parents offer their children money according to their grades in the school is a good idea.The reason are as following. First of all, a kid should not be evaluated only by his or her curricular performance.Some children are good at studying, whereas some children have talent in exercising. Even those who get a medium performance in study or sport-not the best nor the worst-may have other advantages. For example,they are always elected to be the leader in a group because they take care of friends or they are very thoughtful. It is biased to adopt single-standard on judging children and will put into children wrong concept that grades is more important than any other areas. Secondly, in order to encourage children, parents may have several choices besides money. For instance, offering children presents they want or taking children to the place they are longing for such as amusement park.In such ways, parents can also produce memorable experience with children. When children grow up, they will not focus on pursuing money so much,instead, they will know that there is something more critical than money like family and friends. The last but not the least,offering money will result in keeping parent-child relationship on money base.Once parents keep giving money to their kids and requesting them to score high, parent themselves will probably be affected. Parents will no longer concern about other aspects except for the grades. They do not care about children' real interests and moods,day by day, the relationship between parents and kids will get worse and insulated. Some children even start to resist and go on the wrong way. Hence, although in short time, stimulating children to study hard by providing money seems to be an effective approach, in the long run,it might have more negative influence than positive one.
