There really is only one way to judge the success of an educational program. Education, if done properly, is supposed to teach people to do things. So when judging the educational software the right question is: "Do students who use these programs get better at doing things?" This is a difficult question to answer. We do try to answer it here, but bear in mind that real answers to this kind of question can take many years to find out. We know that students can memorize answers for short periods of time. But we are interested in whether they can get better at doing things over long periods of time. It is a good idea not to confuse testing with results.
