【摘要】：高中阶段立体几何一章的内容是学生学习的一个难点,从教学环节查找原因,认为教师对本章的备课仍然存在问题,这会导致学生解题中缺乏空间想象能力,课堂教学效果低下,如果教师在课前的备课环节做好功课,即研读教材,了解学生,备好教法,备活过程,备清自己,对改进教学会有极大的帮助。我们在文献研究的基础上,对教师的备课现状进行了问卷调查研究,从发现的问题出发,开展教学实践研究,采用两个平行班进行教学实践,在实验班的教学是在有效备课前提下完成的,在对照班仍然采取常态教学模式,并做出了案例分析。研究认为教师们发挥有效备课的作用,能够培养学生画图能力和空间想象能力,发展学生数形结合思想,培养学生主动探究知识的意识,在体验数学美的过程中激发学生的学习兴趣,从而培养学生勤于思考、勤于动手的良好品质。
[Abstract]:The content of the chapter on solid geometry in senior high school is a difficult point for students to learn. Looking up the reasons from the teaching links, the author thinks that there are still problems in preparing lessons for this chapter, which will lead to the students' lack of spatial imagination ability in solving problems. The effect of classroom teaching is low. If teachers do their homework well in the preparation of lessons before class, that is, reading textbooks, understanding students, preparing teaching methods, preparing the process of life and making clear of themselves, it will be of great help to improve teaching. On the basis of literature research, we have conducted a questionnaire survey on the present situation of teachers' preparation of lessons. From the point of view of the problems found, we have carried out a teaching practice study and adopted two parallel classes to carry out teaching practice. The teaching in the experimental class is completed under the premise of effective preparation of lessons, and the normal teaching mode is still adopted in the control class, and the case study is made. It is believed that teachers can play an effective role in preparing lessons, cultivate students' ability to draw pictures and visualize space, develop students' thoughts of combining numbers and shapes, and cultivate students' consciousness of actively exploring knowledge. In the process of experiencing the beauty of mathematics, we can arouse the students' interest in learning, so as to cultivate the students' good quality of hard thinking and practice.
