【摘要】：教材是数学教学最常用的工具之一,而它的关键模块之一则是例题。因此,教学的效果怎样,很大程度上取决于教师对教材例题的使用。为了解高中数学的教学现状,需要对教师对教材例题的认识和使用情况有所研究。本研究从苏教版高中数学教材出发,通过问卷法、课例分析法、访谈法调查了数学教师对教材例题的满意程度和使用情况,依此向高中数学老师给出相关的一些建议。问卷法主要考察了常州市和无锡市的一些教师,大致知道了高中教师对教材例题的认识和使用情况。课例分析法选取了《函数的零点》、《任意角》、《等差数列的前n项和》三个课例,通过深入真实的课堂,根据对课堂教学真实情境的考察,掌握教材例题的处理方式。访谈法选取了常州市具有代表性的三所高中各4名教师进行咨询。考察了不同学校的数学老师对教材例题的认识和使用方式上的共性和差异性,深入认识各自使用例题的意图。研究的结论:在认识上,教师对教材例题并不是完全认可,总体在“满意”和“基本满意”之间。其中教师对教材例题的一般性、科学性评价很高,对教材例题的难度、题量等评价较低。在使用情况上,在实际教学中,有大约50%的例题来源于教材。其中,教材例题主要用于概念巩固和解题示范,通常会经过变式之后再使用,对它们的直接使用较少。研究的建议:教师要进一步认清例题的关键性,要继续提高自己的专业水准。对于教材例题题量过少、难度偏简单的情况,教师要根据学生的接受能力,对教材例题加以合理的变式,得到适切于学生的问题,才能充分实现教材例题的价值。
[Abstract]:Teaching material is one of the most commonly used tools in mathematics teaching, and one of its key modules is an example. Therefore, the effect of teaching depends to a great extent on the use of examples of teaching materials. In order to understand the present situation of mathematics teaching in senior high school, it is necessary to study teachers' understanding and use of teaching materials. Based on the teaching materials of senior high school, this study investigated the degree of satisfaction and application of mathematics teachers to the examples of teaching materials by questionnaire, case analysis and interview, and gave some relevant suggestions to senior high school mathematics teachers. The questionnaire method mainly investigates some teachers in Changzhou and Wuxi, and knows about the understanding and use of the textbook examples by senior high school teachers. The method of lesson case analysis selects "Zero of function", "arbitrary angle", "the first n items of < equal difference series" and > three lesson examples, through deep into the real classroom, according to the investigation of the real situation of classroom teaching, grasps the way of dealing with the example of teaching material. The interview method selected four teachers from three representative high schools in Changzhou City to consult. This paper investigates the generality and difference in the understanding and use of examples of teaching materials by mathematics teachers in different schools, and deeply understands the intention of using examples in different schools. The conclusion of the study is that teachers do not fully agree with the examples of teaching materials, but generally between "satisfaction" and "basic satisfaction". Among them, teachers have a high scientific evaluation of the textbook examples, and low evaluation of the difficulty and quantity of the textbook examples. In practical teaching, about 50% of the examples come from teaching materials. The examples of teaching materials are mainly used for conceptual consolidation and problem solving demonstration, which are usually used after variation, but less in direct use. Research advice: teachers should further understand the key of the example and continue to improve their professional standards. For the situation that the textbook examples are too small and the difficulty is too simple, according to the students' receptive ability, the teachers should make a reasonable variation of the textbook examples to get the appropriate problems for the students, so that the value of the textbook examples can be fully realized.
