一、我为什么采用“讨论式”教学我们大丰桥中学是红桥区的一所普通的初级中学,学生缺乏较好的学习习惯和知识基础。升入初二,普遍感到几何难学。学到“命题的证明”,进行简单的推理论证时,两极分化的趋势就比较明显了。大部分学生,一见证明题就束手无策,其中有的象是心里明白,但是写不出来,渐渐地丧失了学好几何的信心。课外作业不是胡写一气,就是抄袭别人的,交差了事。为了使学生切实学会所讲的知识,我对作业采取面批面改。结果还是讲一题会一题,换一个类似的题,就又发呆了。面对这种状况,迫使我对教学进行反省。
I. Why do I use “discussion” teaching We Dafengqiao Middle School is an ordinary junior high school in Hongqiao District. Students lack good study habits and knowledge base. Ascended to the second day, it is generally difficult to learn geometry. After learning the “proof of the proposition”, the trend of polarization is more obvious when simple theoretical proofs are made. Most students are helpless when they see the proof. Some of them seem to understand it, but they cannot write it. Gradually they lose confidence in learning geometry. Homework is not a matter of writing or plagiarism. In order to enable students to truly learn what they are talking about, I have to face-to-face changes to my homework. The result is still a topic, and for a similar question, it will be a daze. Facing this situation, I was forced to reflect on teaching.
