教师讲解示范例題 对数学課的教学来說,当然讲清数學的概念和规律是头等重要的任务,不然的話学生就根本学不会数學知識。我这里談的是在基本上听懂了老师所讲的知識后,如何指导学生独立地更好地完成課內外的作业问題。我觉得教师在讲数学的概念、法則、性貭、定理后,接着就要讲这些概念、法則、性貭、定理如何应用的例題,或者通过一些例題来分析所讲的概念、法則、性貭、定理等基础知識,通过这些例題的讲解不仅能促使学生学会数学基础知識如何应用,帮助学生进一步理解基础知識,同时也能启发学生独立思考的方法和途径。究竟怎样来选择例題才能达到上述的要求呢?个人有这样几点体会。一、精心选择例題。例題的来路很广,书上有例題,习題中的有些題目还可以选作例題,課外参考书上也可以挑选些例題,教师自己也可以編拟些例題等等,但問題不在于例題选自何处,而在于所选例題的內容是否确当,教师能否有目的地讲解这些例题。 1.教师耍选用具有代表性的例題,通过这些例題的讲解,启发学生举一反三,触类傍通。教师应该认真研究这些具有代表性的例題,看它能解决什么样的問題,怎样在讲解过程中向学生揭示它的代表性和規律,这样使学生用所学的例題当响导去解决其他一些练习
The teacher explains the example questions For the teaching of mathematics, of course, clarifying the concepts and laws of mathematics is the most important task, otherwise the students will not learn mathematics knowledge at all. What I am talking about here is how to guide students to independently complete homework assignments after they have basically understood the teacher’s knowledge. I think that after teachers talk about the concept, rules, nature, and theorems of mathematics, they will then talk about these concepts, rules, sexual ambiguities, and examples of how theorems are applied, or analyze the concepts, rules, and sexual tropism that are discussed through some examples. The basic knowledge of the theorem, etc., through the explanation of these examples can not only prompt the students to learn how to apply the basic knowledge of mathematics, help students to further understand the basic knowledge, but also can inspire students to think independently and approach. How do you choose examples to meet the above requirements? Personally, there are several experiences. First, carefully select examples. The examples have a wide range of directions. There are examples on the books, some of the exercises can also be selected as examples, extra-curricular references can also be selected as examples, and the teachers themselves can also prepare examples, etc., but the problem is not in the examples. Where selected, but whether the content of the selected sample questions is correct, whether the teacher can purposefully explain these examples. 1. The teachers choose to use representative examples. Through the explanations of these examples, students are inspired to follow the example. Teachers should carefully study these representative examples to see what kind of problems it can solve, and how to reveal its representativeness and rules to the students during the course of the explanation. In this way, students can use the examples they learned to solve other exercises.
