众所周知,在我国的传统数学教学过程中,十分注重“变式教学”,正因为运用了“变教学”,我国学生在具有良好的基础知识和熟练的基本技能方面大大超过了西方国家的学生.但是我国学生在动手能力和解决比较复杂的或结论开放的数学问题上却逊于美国学生也是不争的事实.这是为什么?反 As we all know, in our country’s traditional mathematics teaching process, we pay great attention to “variant teaching”. Because of the use of “changing teaching,” our students greatly surpassed Western students in terms of having good basic knowledge and skilled basic skills. However, it is an indisputable fact that our students are inferior to American students in their ability to work and solve complicated or open-ended math problems. Why is this?
