Normative diagnosis of the level of a learning-cognitive activity in a schoolchild

A method to establish the state (level) of learning-cognitive operations in a child is presented. The method is based on the study of the ability to analyze an object as a system of interrelated elements, to perform reflexive consideration of one's own actions, to restructure the operational schemes given by adults. It is shown that fixation on the search of the essential property of the object (a genesis principle), seeing a relation between object-content elements of the operations comprise most important psychological indicators of the developmental status of learning-cognitive operations in schoolchildren.
