| Mathematics teaching of senior high school depends on classroom teaching, sohow to improve classroom teaching quality and effectiveness, how to help student tolearn and promote students'lifetime development are important issues facing teachingstaff.According to mathematical curriculum in primary and middle school of Shanghai, the study is directed by Meta-cognitive Theory, constructivist learningTheory, Cognitive Load Theory Zone of Proximal Development Theory andMathematical Theory of Double-base Teaching; in addition it is based on its previousresearch on the present classroom teaching in senior one and the analysis of studentscognitive level in order to solve these problems.
