The author of this article contends that there is more to teaching than the teacher possessing a body of information and using group dynamics in passing the information to the students. One-to-one teaching could be better used through the study of behavior and the individual verification of ideas. The author refers to research in the utilitarian verification of ideas and the frequency of error, and he takes note of the difficulties inherent in translation. The role of the teacher in this age of new training methods is clear. He must not only explain concepts but also the different expressions used to refer to them. Also cited is the use of questionnaires and the student analysis of information. The author considers telematics to be a most important source of information.
