我们都知道,数学教学成功的关键在于教师能否培养学生产生对该学科的兴趣。而精心设计的课堂导入,可使学生尽快进入求知的兴奋状态,提高学生学习的积极性和主动性,为课堂教学打下良好的基础。下面,笔者略举几种初中数学新课的导入方法,和大家共同探讨。1复习旧知识导入通过复习旧知识,设计新问题启发思考,在学生产生连续思维“意犹未尽”时导入新课。(1)讲“正方形”一节时,可先复习提问:矩形有何性质?菱形有何性质?有无既是矩形,又是菱形的平面图形?若有,请画出来,这是揭示课题。(2)讲“经过三点的圆”时,先让学生画过一点
We all know that the key to the success of maths teaching is whether teachers can develop students’ interest in the subject. The well-designed classroom introduction, enabling students to enter the excited state of knowledge as soon as possible to improve the enthusiasm and initiative of students to learn, lay a good foundation for classroom teaching. Below, I give a few examples of junior high school mathematics introduction of new methods, and we discuss. A review of old knowledge import Through the review of old knowledge, design new questions inspired thinking, in the students to produce continuous thinking “indefinable ” into the new class. (1) When talking about the “square” section, you can first review the question: what is the nature of the rectangle? What is the nature of the rhombus? Are there any rectangles and diamonds? If so, please draw the outline Question. (2) Say “” after three o’clock ", let the students draw a little
