The article is devoted to the definition of mnemonics as a technology and methodology in pedagogical science. The author of the article aims to show the difference between the concepts of methodology and technology of mnemonics, as well as to determine the criteria of technology and methodology in pedagogy. The study reveals a contradiction in the use of the term "mnemonics" in pedagogical science due to the lack of differentiation of "methodology" and "technology" concepts. The methodological basis of the research was the study and analysis of scientific works by the researchers of the Russian pedagogical school. It is revealed that the pedagogical technology of mnemonics and the pedagogical methodology of mnemonics have absolutely different bases. The practical significance of the research lies in the fact that the currently developed methods and technologies must meet certain criteria that determine their significant organizational, methodological, legal and conceptual differences.
