The purpose of the study is the development and practical testing of the technology of Mind Mapping and its influence on the cognitive development of schoolchildren. The subject of the study is the content and organization of the technology of Mind Mapping. Methodology. A modern pupil should be able to independently acquire knowledge, apply them in practice to solve various problems, work with various information, analyze, generalize, critically think, and seek rational ways in solving problems. The development of these abilities can be achieved if the learning processes activate thinking processes. The universal tool for development of thinking abilities is the technology of Mind Mapping: the method of creation and application of educational intelligence cards. This technology is based on the research of the English psychologist T. Byuzen and the Russian professor M. Bershadsky. For several years, we conducted research on the use of the technology of Mind Mapping at lessons in general schools in Kazakhstan. The results of the research showed the effectiveness of this technology in the educational process. Conclusions. At all participants of the study: students, teachers there were positive changes. Mind mapping technology promotes cognitive development of the individual, mental abilities, intellect. There is a vast development of all kinds of mental processes, such as perception, memory, the formation of concepts, problem solving, imagination, logic.
