The results show that students have inductive, theoretical and mathematical thinking, the ability to operate with numbers and computational skills, they have a medium level of ability to identify new connections, master the general techniques that lead them to solve new problems and to mastering new knowledge. As in the previous subtest, those who easily cope with these tasks and those who have difficulties are clearly distinguished.

The results of the study on the subtest «Spatial Imagination»: 24.8 % of students showed high results, 23.0 % – «Above the norm», 24.5 % – «Norm», 15.7 % – «Below the norm» and 11.9 % – low (Fig. 3.16).

The results indicate that students have a spatial imagination, visual – effective thinking and constructive abilities at the average level, with the distribution of students in assessment groups is almost equal.

The results of the study on the subtest «Spatial Generalization» are traditionally low: only 5.1 % received high marks, 9.0 % – «Above the norm», 16.2 % – «Norm», 19.0 % – «Below the norm» and 50.7 % – low (Fig. 3.17).

The results show that visually – effective thinking, the ability to three – dimensional analysis, the operation of spatial images and generalizations in students are developed at a low level.
