在多年的教学实践中,笔者常常听到一些老师这样抱怨:这种类型题我在课堂上反复强调,从条件分析到步骤板书,环环相扣,天衣无缝,然而让学生自己动手做时,总是漏洞百出,学生解题能力就是得不到提高。诚然,造成这种结果的原因有多方面,但不可否认的是,我们的例题教学确实存在不少问题。数学例题教学是知识由产生到应用的关键一步,然而很多时候学生的“学”与老师的“教”没能融为一体,因而出现上述情况也就见怪不怪了。
In many years of teaching practice, I often hear some teachers complain: This type of question I repeatedly stressed in the classroom, from the analysis of the conditions to the steps of the book, interlocking, seamless, but let the students do it yourself, the total Is full of loopholes, students can not improve the ability to solve problems. It is true that there are many reasons for this result, but it is undeniable that there are indeed many problems with our example teaching. Teaching mathematics is a crucial step from knowledge generation to application. However, in many cases, the students’ learning is not integrated with the teacher’s teaching.
