The purpose of this study was to quantitatively describe secular changes in abstracts of graduation work at a Secondary School in Tokyo. We used text-mining techniques to achieve this goal. The measures we used in this study were length, potential vocabulary size per 100 words, readability, and topic distribution of the abstracts. Through visualization process of them, we found three features of secular changes of the graduation work. First, student’s style of writing was getting elaborate. The length got longer, and the readability lower. Second, the allocation of topics related to the concept of investigation or questionnaire was increasing since 1995. It suggests that the number of empirical study is increasing as written in the purpose of graduation work. Third, the topic related to the concept of books or library was decreasing while the topic related to the concept of internet was increasing. This implies that the way of searching for knowledge is shifting from books to internet. These results suggest that we should focus on these abilities in future effect-validation study of the graduation work.
