There was a time when parents who wanted an educational present for their children would buy a typewriter, a globe or an encyclopedia set.?

　　Now those 21 seem hopelessly old _ fashioned: this Christmas, there were a lot of22computers under the tree. 23 that computers are their key to success, parents are also frantically insisting that children24taught to use them on school-as early as possible.?

　　The problem for schools is that when it25computers, parents don’t always know best. Many schools are 26 parental impatience and are purchasing hardware without 27 educational planning so they can say, “OK, we’ve moved into the computer age." Teachers 28 themselves caught in the middle of the problem-between parent pressure and 29 educational decisions.?

　　Educators do not even agree30how computers should be used. A lot of money is going for computerized educational materials 31 research has shown can be taught32with pencil and paper. Even those who believe that all children should33to computer warn of potential34to the very young.?

　　The temptation remains strong largely because young children 35 so well to computers. First graders have been 36 willing to work for two hours on math skills. Some have an attention span of 20 minutes.?
