Dialectic approach to formation of the concept of "biosphere"

The article deals with the problem of derivation of concepts as a didactic tool for the formation of productive knowledge in the educational process. The author presents the biosphere as an object of deducing the concept, and as a method - dialectical, deployed in interdisciplinary connections through the identification and resolution of contradictions. The presented material claims to a certain degree of theoretical and methodological argumentation in defense of the need to reform the competence-based idea of education.
