the movement to use computers more in education naturally includes many unrelated ideas, methods, and pedagogies since there are many uses for digital computers. For example, the fact that computers are naturally good at math leads to the question of the use of calculators in math education. The Internet's communication capabilities make it potentially useful for collaboration, and foreign language learning. The computer's ability to simulate physical systems makes it potentially useful in teaching science. More often, however, debate of digital education reform centers around more general applications of computers to education, such as electronic test-taking and online classes.
The idea of creating artificial intelligence led some computer scientists to believe that teachers could be replaced by computers, through something like an expert system however, attempts to accomplish this have predictably proved inflexible. The computer is now more understood to be a tool or assistant for the teacher and students.
Harnessing the richness of the Internet is another goal. In some cases classrooms have been moved entirely online, while in other instances the goal is more to learn how the Internet can be more than a classroom.
