FEATURES OF THE SEMANTIC SPACE OF EDUCATIONAL TEXTS ON THE MICROCOSM PHYSICS

The article is devoted to the problem of identifying the semantic proximity between key ideas and concepts in educational texts on physics of the microcosm, and identifying the features of their semantic space. The texts of university textbooks and Wikipedia articles collected in one file are analyzed. Quantitative linguistics methods are used, including calculating the frequency of use of terms and marker words related to the most significant ideas, as well as comparing the distribution of concepts in physics textbooks. Special computer programs written in ABCPascal are used to remove punctuation and stop words from the text and determine the number of occurrences of various terms. The cosine similarity measure and semantic distanc-es between concepts are also calculated. As a result: 1) the key physical concepts of-ten used in the study of microcosm physics are identified; 2) the most important ideas of microcosm physics are listed: the idea of physical characteristic quantization of microobjects, the idea of wave-particle dualism, the Heisenberg uncertainty principle; 3) the cloud of concepts and pie chart are constructed showing the proportion of each of them in the text; 4) the matrix of proximity of concepts and matrix of semantic distances between them are obtained; 5) graphs are constructed that model an essential part of the semantic space of educational texts on microcosm physics and show the closest connections between key concepts and ideas.
