我们知道,好的开始是成功的一半。一堂课上得好不好,效率高不高,很大程度上与这堂课的导入方法有关系,初中数学课堂同样也是如此。数学课堂不同于语文、历史、地理这些学科,数学课堂的内容以数理与图形为主,主要强调学生的抽象思维能力,强调的是逻辑推理能力的培养(当然也有一部分形象思维的东西,如几何的部分内容,但形象思维的内容又常常是和逻辑推理问题融合在一起的),而所涉及的人文趣味方面的内容较少。因而,上课时学生容易产生倦怠心理,尤其是那些学习能力有所欠缺、成绩不理想的学生,更是缺乏学习的耐心与解决疑难问题 We know that a good start is half done. A good lesson in a class, high efficiency is not high, to a large extent, the introduction of this lesson has a relationship, the same is true of the junior high school mathematics classroom. Mathematics classroom is different from the subjects of language, history and geography. The content of mathematics classroom mainly focuses on mathematics and graphics, emphasizing students' ability of abstract thinking, emphasizing the cultivation of logical reasoning ability (of course, there are also some things that image thinking, such as geometry Part of the content, but the content of the image of thinking and logic are often the problem of inference together), and the content of the humanities involved less. Therefore, students are prone to burnout during class, especially those who lack learning ability and unsatisfactory performance, but also lack the learning patience and solve difficult problems
