很多学生学完高中数学新课程标准教材必修模块二的《立体几何》后,感觉心里不踏实.笔者在教学中编拟了一串小问题,利用这些小问题可以把整个模块二的立体几何知识都串起来,无论在模块二的复习中还是在高三第一轮的复习备考中都不失为一串好题,通过这一串小问题的学习还可以增加学生学习数学的信心和探究数学的兴趣. Many students learn high school mathematics new curriculum standard textbook compulsory module two “three-dimensional geometry”, I feel not practical. The author in teaching a series of small problems, the use of these small problems can be the whole three of the three-dimensional geometric knowledge module All string together, both in the review of Module 2 or in the first round of the high school review preparation is a good series of questions, through this series of small problems can also increase the confidence of students to learn mathematics and explore the interest of mathematics.
