Outline of Final Research Achievements

This research conducted various analyzes based on the scientific terms appearing in Japanese textbooks of mathematics, science and information used in junior high school and high school. The total number of indexes collected is 12015. There are 2761 junior high school indexes and 9254 high school indexes.
Comparing the number of scientific terms from the present and 10 years ago, the number of scientific terms decreased in all subjects. The rate of increase is small in mathematics and large in science and technology. There is no common scientific term that appears in the current three subjects of mathematics, science, and technology. There are 13 common scientific terms that appear in the two subjects.
The change in the number of scientific terms in high school is increasing in order of 20 years ago, 10 years ago, and now. The rate of increase is about 30% from 20 years ago to 10 years ago, and about 5% from 10 years ago to now.

Academic Significance and Societal Importance of the Research Achievements

本研究は、日本の数学・理科・情報（技術）の教科書に出現する科学用語を様々な方法で分析した。この結果は、日本の中学校と高等学校の科学教育に関する実態を、20年前と10年前と現在の比較や、各教科間の違いを数量的に明らかにすることができた。また、共起ネットワーク分析をすることによって、各教科の科学用語の相互関係を視覚的に把握することができた。
