The purpose of this study was to :(1)investigate the percentage of highachievefs and underachievers in English;(2)identify the differences between highachievers and underachievers in their self─concept on English learning ability, the achievement motivation of English learning, and their learning behaviors on English;(3)analyze the variances of English achievement accounted for by the foregoing three variables;and (4)test a proposed causal path that the self─concept of English learning ability would influence the achievement motivation of English learning, which in turn influences English learning behaviors, and then finally influence students’ achievement in English.The statistics adopted in this study included Pearson Product─Moment Correlation, test of significant difference between two percentages, two─factor ANOVA with equal N, step─wise multiple regression. And path analysis.The major findings of this study were as follows:\r1. The percentage of highachievers and underachievers in English ere significantly different between boys and girls.2. For highachievers, their self─concept of English learning ability, achievement motivation in English and their English learning behaviors were significantly better than those of underachievers’.3. Pronunciation practice, one of the English learning behaviors, was found to predict better the achievement in English for junior high school students.4. The proposed causal path that the self─concept of English learning ability would influence the achievement motivation of English learning, which in turn influences English learning behaviors, and finally influence English achievement was supported only by the generalizations, but not by any specific group involved in this study. |
