  Analyzed models of learning, which take into account that: 1) the rate of
increase of student's knowledge is proportional to the difference between
levels of teacher's requirements and prior knowledge; 2) if the requirements
are too high, then student motivation decreases and he stops learning. Was
proposed: 1) a one component model, coming from the fact that the training
information consists of equal elements; 2) a two component model that takes
into account that knowledge is assimilated with varying strength, 'trustworthy'
knowledge forgotten much slower then 'weak'; 3) two component model, which
takes into account the transition of 'weak' knowledge in 'trustworthy'
knowledge. The solution of the five predictors and optimization problems of
learning theory are represented.
