Educationally-conditioned differences in computer use increase dramatically. Technology and society critics in this regard object the progressive informatization of all areas of life to lead to a new social splitting. Like all end-users of computer systems, pupils also approach new application software with different technological experiences and different insight ability. Some need only few minutes, in order to intuitively understand the improved handling possibilities of a new user interface, a new system version, or a completely new application system. Non-intuitive and especially learning disabled pupils need more time. In this regard, first of all further research efforts are required in order to be able to offer ability and talent-adapted help systems and accordingly adapted dialogue interfaces.
