新课的导入是一门科学,也是一门艺术。良好的开端等于成功的一半,数学新课导入能否激发学生的积极性,关系着课堂教学质量的优劣。结合多年教学实践,我做了如下探讨:一、逐步引入法,即以知识本身的结构启迪学生思维,导入新课例如,在七年级“有理数及其运算”导入负数过程中,就可以从数的产生逐步引入负数。学校知识竞赛评分标准是:答对1题奖10分,答错1题扣10分,每个队基本分为0分,由此就出现了 The introduction of the new course is a science, but also an art. A good beginning is equal to half of the success. Whether the introduction of new math class can stimulate the enthusiasm of students is related to the quality of classroom teaching. Combined with years of teaching practice, I made the following discussion: First, the gradual introduction of law, that is, the structure of knowledge to inspire students thinking, into a new lesson, for example, in the seventh grade “rational numbers and their operations ” into the negative process, you can The introduction of negative numbers gradually introduced. School knowledge contest grading standards are: Answer 10 questions on a question, answer the wrong 10 points 10 points, each team is basically divided into 0 points, which appeared
