在小学毕业生的数学总复习中,孩子常会暴露出在基础知识掌握和综合运用数学概念的能力上这样或那样的一些问题。灯光下,望着孩子凝视题目、面有难色的神情,家长无不想助一臂之力。于是往往有这样的做法: 家长包办代替做出答案,但剥夺了学生的思维,使他们没能真正掌握解题的规律,各换一个结构类似的题目,孩子仍感到无从下手。或者,家长设x、y,用代数求出结果,但代数解法与算术解法是两种不同的思路,因此孩子可能还是
In the general review of maths for primary school graduates, children often reveal some kind of problems, one way or another, in their ability to master basic knowledge and apply mathematical concepts comprehensively. Under the lights, looking at the child staring at the subject, face hard color look, parents are all want to help a hand. So often there is such a practice: Instead of answering the questions, parents deprive the students of thinking so that they can not really grasp the law of problem solving. Or, parents set x, y, using algebra to find the result, but the algebraic solution and arithmetic solution are two different ideas, so the child may still be
