Also, the article explicitly outlines and suggests concrete ways and methods for the formation and development of sustainable positive motivation. It is believed that content consistency during the process of studying, methods of teaching, consideration of students’ cognitive needs and interests are the main factors in the process of educational motivation formation and these elements strengthen all components of motivation: needs, aspirations, interests, emotions, motives themselves, which in turn contribute to the deepening and expansion of the sphere of students’ cognitive activity. Conclusions. Consequently, we considered some of the most important, in our opinion, conditions and ways of forming positive, stable motivation for students’ educational activities. To establish such a motivation, one should use not only one way, but all ways, methods in a certain system, in a complex, because none of them, without others, can play a decisive role in the formation of motivation. Consistency of the educational content and ways of filing it with cognitive needs and students interests counteracts the formation of a negative educational result. Optimally selected material strengthens all components of motivation: needs, aspirations, interests, emotions, motives themselves. Formation of a stable motivation level requires teacher to select appropriate educational materials that would represent cognitive, communicative, professional values, stimulate mental activity, and promote deepening and expansion of cognitive students’ activity.
