n/teaching and "non-stop" retraining applied in some cases will become a universal and mandatory phenomenon, whereas the boundary between necessary and desirable knowledge will become more vague and conventional. In modern conditions active and purposeful studying of someone's future sphere (spheres) of activity should start 4-5 years prior to entering the university. Considerable development will be seen in "preventive" (pre-emptive, anticipatory) education taking into account prospects of development of science for 3-5-10 years from no on. Masterful knowledge of methods of scientific-analytical and creative thinking is becoming the same social standard and a sign of affiliation to elite social groups as, for example, the presence of higher education diploma. The law of inverse proportionality of controllability and the ability to development says the more the system is controllable, the less it is capable of development. Controllable development may only be overtaking/catching up /. Now, a few thoughts about errors in the course of training. Traditional approach tends to consider an error as the lack of learning, assiduity, attention, diligence, etc. As a result the one to blame is a trainee. Error should be perceived as a constructive element in the system of heuristic training. An educational institution is just the institute where the person should make mistakes under the guidance of a teacher. An important element of cognitive system is professional terminology. The lack of knowledge of terms would not release anyone from the need to understand ... Each term contains the concentrated mass of nuances and details distinguishing the scientific vision of the matter in question from the ordinary, unscientific understanding ... It should be mentioned that the process of teaching/educating/is a stress which has pluses and minuses, whereas the process of studying is a much smaller stress. One of the main tasks in terms of (self-) education may be the formation of active desire (internal requirement) to study and be engaged in (self-) education with independent search of appropriate means and possibilities. Special consideration should be given to teaching/training means and methods, ie what is comprehensible to one group of trainees may be useless for others. Major differentiation would be seen in age categories plus individual features. Training games are quite a universal tool used for a wide range of subjects and development of practical skills, since the game reflects the trainee's behavior in reality. It is a system that provides an immediate feedback. Instead of listening to a lecture the trainee is given the individual lesson adapted for his/her needs. Game is modeling of reality and method of influencing it by the trainee. Some minuses of game include conventionality and schematic nature of what is going on and the development of the trainee's behavioral and cogitative stereotypes. Major strategic consequence...
