Stressed parents only know too well that in many cases, the energy of their children seems to be never exhausted. In many cases, the children are put in front of television if one wants to enjoy a few quiet hours. Unfortunately, the contents of many television broadcasts don’t seem to be very child-friendly although they where explicitly made for children. Violences scenes and senseless stories are shown in the kid’s program. Next to that, sitting sitting in front of television is not interactive, i.e. the program cannot be affected by the child, and thus can become rather boring after a while. Computer programs seem to be a bad alternative in this case. Only too often one is warned in the media of the dangers of the Internet. And also the discussions around so-called “killer games” emerges now and then in the media. But there are also completely different examples. Many computer games permit playing and investigating in a secured surrounding. In many cases, handling a teaching program can even reduce the fear of learning, since teaching programs are conceived such that they teach handling complex topics easily. Thus one kills two birds with one stone. The children are put calm, and at the same time, can one can enjoy the good feeling that they use their time very in a very valuable way.
