Traditionally, people have tried to compare the effectiveness of traditional teaching with Computer Aided Learning (CAL), however, it is very difficult to work out which of them is best.

However, we should highlight that although we use the new technologies, the figure of the teacher will always be necessary and that in the design of computer applications the interaction of the technician with an expert in educational methods is very important
