Abstract: Questionnaires were group administered to 119 high school students, this study examined theinfluence of motivation, learning strategy, and intelligence factors on the academic achievement of thestudents. Correlation, regression, and path analyses indicated that motivation, learning strategy, and IQwere not only correlated with academic achievement, but there also was a causal relationship amongthem. The study demonstrated that self-efficacy, intrinsic motivation, master goal, learning strategy, andIQ were positively correlated with achievement. Extrinsic motivation, performance goal were negativelycorrelated with achievement. Moreover, IQ(β= 0.476), learning strategy (β= 0.220),self-efficacy(β =0.207), and master goal (β= 0.185) influenced academic achievement directly, intrinsic motivationinfluenced academic achievement indirectly by raising the level of the use of learning strategy.

Key words: motivation factor, learning strategy, level of intelligence, academic achievement
