Knowledge of basic principles and the application of these principles through problem solving is the key to a deeper understanding of science. It would be wrong to give the impression that science is all easy fun. Indeed success in every field of technology, in medicine, in agriculture, in mining and indeed in the management of all of these fields of endeavour calls for a thorough understanding of basic physics and chemistry. Such understanding can only be obtained through disciplined and directed study. This need not be drudgery and should be a deeply rewarding and satisfying experience.
Computers can enhance the experience for both learners and teachers.
