实践证明,学生的发现欲望是无穷的,教师过多的讲解只会抑制学生的探究热情,而教师适当的放手更能激发学生的智慧.本文以2014年苏州数学中考题为例,谈谈如何以学生的“发现”为目标,进行习题讲评教学.题目如图1,二次函数y=a(x2-2mx-3m2)(其中a,m是常数,且a>0,m>0)的 Practice has proved that the students’ appetites for discovery are endless, teachers’ excessive explanations only restrain students’ enthusiasm for inquiry, and teachers’ proper letting go can further stimulate the students’ wisdom.Taking the 2014 Suzhou Mathematics Test as an example, The student’s “discovery” as the goal, the problem commentary teaching. The subject is shown in Figure 1, the quadratic function y = a (x2-2mx-3m2) (where a, m is a constant, and a> 0, m> 0 )of
