新编十年制数学课本第三册第一章的教材内容是平几知识。初二学生开始学习平几时,一般都感到象初学外语时一样的新奇。学习的积极性一般都很高。这时教师要善于引导学生,教育并鼓励学生应为实现“四个现代化”而努力学好文化科学知识。告诉学生学好平几的关键,就是一开始就要重视基础知识的学习,所谓万丈高楼从地起就是这个道理。有了良好的基础,学生学习的兴趣就会越学越浓厚,越学越灵活。过去的教学实践反复证明了这个事实。我们都知道初二学生的年龄特点,精力旺盛,活动能力强,也爱思考问题。在学习中一遇困难就缺乏刻 The textbook content of the first chapter of the new tenth-century mathematics textbook is the same as that of the first chapter. When students of the second grade begin to study for a few hours, they usually feel the same novelty when learning a foreign language. The enthusiasm for learning is generally high. At this time, teachers should be good at guiding students, educating and encouraging students to strive to learn cultural and scientific knowledge in order to achieve “four modernizations.” The key to telling students how to study well is to pay attention to the basic knowledge from the outset.
