Abstract: Learning strategies and teaching strategies have important impacts on student's academic achievement,while there are few studies on the relative importance between the two factors in China.Based on a survey conducted in a province in eastern China by China Collaborative Innovation Center on Basic Education Quality Monitoring,this research applies HLM and Shapley decomposition method to estimating and comparing the effect sizes of learning and teaching strategies for primary and lower secondary students.With regard to the econometric analysis on students at different educational levels,at primary level,the effect size of teaching strategies is larger than that of learning strategies,while at lower secondary level,the effect size of learning strategies is larger than that of teaching strategies.With an econometric analysis on students at different ability levels,and to those primary students with relatively low ability,the effect size of teaching strategies is larger.While to those primary students with relatively high ability,the learning strategies obtained by students are more important.To lower secondary students,the effect size of learning strategies are bigger regardless of the level of students.In addition,this research also found that,adequate educational investment,high quality school infrastructure and teaching personnel,student's individual study grit,and effective learning strategies,are the four major elements for a high school performance of Chinese students.

Key words: learning strategies, teaching strategies, academic achievement, Chinese style education
