CONDITIONS OF FORMATION OF SCIENTIFIC CONCEPTS WHEN TEACHING MATHEMATICS AT SCHOOL: SOCIO-CULTURAL APPROACH
Theoretically substantiated technology teaching geometry of younger adolescents, focused on the development of the valuable maintenance of geometrical concepts. From the standpoint of sociocultural approach phase of the cycle is considered the value of development - communication: understanding the formation and ways of acting with geometric concepts. Are allocated communication steps, the content of which is determined by the structure of activity-related components of geometric concepts, including both substantive action and real cognitive and formal operations. The scheme of the organization develop the valuable maintenance of geometrical concepts in the communication process. We consider the content of the stages of development of spatial and logical components of the communication by the example of teaching geometry younger teenagers. Substantiates the experimental confirmation of the hypothesis: efficiency sociocommunicative processes in the learning situation geometry younger teenagers is caused by several factors, among them - the implementation of laws psychodidactic awareness, understanding and synthesis of content and process activities; phased development of a coherent mental structure "image - idea - preconcepts - concept - a system of concepts"; phased development of activity-related components of geometrical concepts: substantive action, real cognitive operations, formal operations.
