| Outline of Final Research Achievements |
The growth process of a terminological network has been analyzed to reveal the developmental process of knowledge in textbooks. We construct terminological networks, with vertices representing terms and edges representing co-occurrence of terms in a paragraph. Our primary results are as follows. (1) New term appears constantly as a whole, while many more new terms appear in some sections. (2) Most terms are connected to other terms consistently. (3) The average number of terms that are directly connected to a term is increasing. Terms are indirectly connected through two or three terms on average. (4) The degree of centralization (i.e., few terms are connected to many terms directly or facilitate indirect connection between terms) is deteriorating. These results differ from the results obtained when terms appear randomly in the textbooks. Characteristics according to subject and school level are also observed.
