随着新课程改革的推进,数学教材经历了“一纲一版”到“一标多版”的过程,现行各版本数学教材中的许多内容存在着简化定理公式的提出过程和证明推导过程的现象,忽略了其中的发现、探索过程.心理学研究表明:不经过学生个人亲身探索和发现的过程,要想把已知的真理变成学生的真知是不大可能的.《义务教育数学课程标准(2011年)》指出:“学生应当有足够的时间和空间经历观
With the advancement of the new curriculum reform, mathematics teaching materials have undergone the process of ”simplifying the theorem formulating process“ and many of the current versions of mathematics teaching materials have presented the process of formulating simplified formulas Prove the phenomenon of the deduction process and neglect the process of discovery and exploration.Psychological research shows that it is impossible to change the known truth into the true knowledge of the student without going through the process of personal exploration and discovery. Compulsory Education Mathematics Curriculum Standard (2011) states: ”Students should have enough time and space experience
