The need for research is due to the insufficient development of the conditions for organizing activities for the formation of cognitive learning activities in students using competence-oriented tasks. The use of competence-oriented tasks in the formation of cognitive learning activities, as already noted, requires additional research. Thus, a number of contradictions have been identified: students need to adequately develop cognitive educational activity so that it meets the modern requirements of society, but the problem of the development of cognitive educational activity in the process of teaching chemistry in secondary school is insufficiently studied in pedagogical theory and practice. These contradictions reflect the relevance of the research topic and allow us to formulate its problem: what should be the competence-oriented tasks for the formation of cognitive learning activities among students?

For the formation of cognitive educational activity, the educational activity of students was organized under the following conditions. Firstly, the development and holding of the "interesting chemistry" circle. Secondly, the creation of work based on the use of specific types of competence- oriented tasks. Experimental work has yielded positive results. Importance of the research: the materials of the article can be useful for school chemistry teachers.
