Abstract
This study was conducted to investigate six subscales of intrinsic motivation in the subjects in junior and senior high school students. The intrinsic motivation inventory was composed of six subscales ; (1)enjoyment, (2)perceived locus of causality, (3)curiosity, (4)challenge, (5)endogenous-exogenous attribution, (6)mastery. Four hundred students were asked to evaluate their intrinsic motivation in five subjects (mathematics, Japanese, English, social studies, science) on five-point scale. According to the results of the analysis of variance, there existed significant differences among the six subscales of intrinsic motivation in each subject. Developmental factor was significant in social studies and differences between the sexes were also significant in Japanese and English.
