Correlations between Changes in Study Habits and Academic Results in Junior High School Students—A Longitudinal Survey at a Private Junior High School

Correlations between changes in study habits and academic results in Japanese junior high school students were investigated through a longitudinal survey. Participants were students enrolled in a private junior high school (N = 170). A questionnaire was conducted twice a year for three years. Moreover, results of regular exams and mock exams were collected. The results indicated a high correlation between scores of subject study habits and academic results. Furthermore, the results of cluster analysis indicated that patterns of changes in learning motivation were classified into four types, and academic records were low in the declining type and considerably declining type. Based on the results above, it is considered effective to detect changes in study habits of each student in early stages through regularly evaluating study habits quantitatively, for improving students’ academic skills.
