大学入学者の学力変化について

―科目変換得点尺度を用いて―

抄録

The present study tried to assess the change in academic achievements of university students after 1 year from the date of the entrance examination by using JFSA Tests and the National Center Tests which measure the level of basic academic achievement aquired in upper secondary school. Every subject's results of monitor examinations for JFSA Tests and the National Center Tests, which covered 8 school years, were compared with the achievements of the former year by means of Academic Subject Score Scales. The results showed the significant decline of achievements in almost all academic subject areas, even if regression effects were taken in account. The decline of Social Studies and Natural Sciences seemed greater than that of Japanese Language, Mathematics and English Language. One of the most important trends of change was that the preexistent differences between students of arts and science courses were enlarged. It is desired that a suitable psychological explanation will be given to those phenomena by future studies.
