传统中学数学教学的模式是数学教师在讲台上为学生讲解课本知识,用粉笔在黑板上书写数学公式、分析数学公式的意义,叙述解题的步骤、方法。这种教学完全是一种灌输性方式,学生处于完全被动的地位,无法调动学生的积极性,更无法提高学生对学习数学的兴趣。导致的结果就是教师在讲台上费劲地讲,学生在台下却兴致不高,甚至有些学生昏昏欲睡。特别是有些讲课声音很小的教师,座位较远的学生很难听到教师在讲些什么,只有少数 The traditional middle school mathematics teaching mode is the mathematics teacher on the podium for students to explain the textbook knowledge, with chalk on the blackboard to write mathematical formulas, analyze the meaning of mathematical formulas, describes the steps and methods to solve problems. This kind of teaching is a kind of indoctrination. Students are in a completely passive position, unable to arouse the enthusiasm of students and can not improve their interest in learning mathematics. The result is that teachers in the podium strenuously speaking, students are not happy under the audience, and even some students sleepy. In particular, some teachers who speak very little voice, students who are far from their seats find it hard to hear what the teachers are talking about. Only a few
