The technology of teaching pupils logical thinking

We regard the innovative educational environment as a means of developing pupils in the process of teaching natural science disciplines. The following was taken into account: the forms of logical thinking are understood as concepts, judgments, inferences; the definition of a concept assumes a classification, which is possible on several grounds. An algorithm for teaching pupils to classify is presented on examples from a school course in biology. The pedagogical conditions of the effectiveness of the formation of logical thinking of pupils on natural science material in the new educational environment are revealed: the use of a system of special tasks aimed at the formation of logical thinking; strengthening the activity ofpupils in solving Olympiad problems; application of the system of didactic games using multimedia presentations.
