“…This interdependence makes the matter of development of spatial ability is very relevant for the students of designing disciplines (Knapp, 2011). Professors-researches have come to the conclusion that in the absence of necessary level of ability of spatial thinking, at the beginning of learning the geometric and graphic disciplines in a university, the additional propaedeutics methods of spatial ability development should be used in parallel with graphics disciplines (Bairaktarova et al, 2015;Varlamova, 2018;Hsi et al, 1997;Williams et al, 2010;Gridina and Andreev, 2018).…”

University professors more and more often face serious problems of learning geometry and graphic disciplines. In this regard, it is very relevant to obtain a maximum efficient method to teach geometry and graphic disciplines. The purpose of the study is to test the hypothesis that the cause of problems arising in the process of mastering the geometric and graphic disciplines is the violation of continuity of the educational material and the low level of spatial ability of students. In the research, interviewing method (testing) and statistic method have been applied to process the results. It is established that spatial imagination helps a person to perceive the shape of geometric objects by involving him/her into the cognitive process of feeling and control of spatial objects. Students who learned in school technical drawing the same as students who did not learn experience difficulties in mastering the geometric and graphic disciplines. For students who learned technical drawing in schools, the cause of bad retention of the material of the geometric and graphic discipline is low geometric spatial ability. For students who did not learn technical drawing in school, but who demonstrated a high geometric spatial ability, the cause of difficulties in the retention of the geometric and graphic disciplines are connected with the violation of continuity of the educational material. To effectively teach the geometric and graphic disciplines, it is necessary to apply methods of developments of the geometric spatial ability and to form the content of discipline using the principle of continuity.

The influence of the ultrasonic treatment of block copolymer solution on its solid-liquid interface behavior was investigated in detail. The surface modification of titanium dioxide nanoparticles in aqueous dispersions of specially tailor-made periodic acrylic acid/isobutylene copolymer by ultrasonic treatment was studied in order to get new approaches for the creation of hybrid composite materials or polymer coatings. The pigment surface modification by the above copolymer was comparatively investigated regarding conventional adsorption as contrasted to an ultrasonic treatment assisted procedure. The course and efficiency of the polymer adsorption onto the pigment surface were quantified by electrokinetic sonic amplitude measurements. The higher efficiency of the pigment surface coating by the copolymer as achieved by ultrasonic treatment in comparison to conventional adsorption is a consequence of ultrasonically induced pigment surface activation. Two perspective avenues of the utilization of the discovered effects for creation of organic-inorganic composite materials are anticipated: the nanoparticles could first be treated by ultrasound in the presence of polymers and so create a surface modifying coating and the second option is an entrainment of the nanoparticles into the monomer matrix which can be polymerized afterward yielding a polymer with immobilized nanoparticles.
