公式是初中数学教材的重要组成部分,是数学知识的主要载体之一.通过公式教学,既能达到强化双基、传授数学学习方法的目的,又能促进学生观察、分析、探索、创新能力的提高,而学生公式掌握得好坏又直接影响其数学的后续学习.因此,公式教学在初中数学教学中占据着十分重要的地位.就公式教学中的三个环节,浅陈陋见.一、公式的推导数学公式的教学,首先要使学生经历公式推导的全过程,掌握公式的推导方法.就此而言,在实际教学中,应有的放矢地
Formula is an important part of junior high school mathematics teaching materials and one of the main carriers of mathematics knowledge.With formula teaching, not only can the purpose of strengthening double base be imparted to mathematics learning method, but also to promote students’ ability of observation, analysis, exploration and innovation Improve, and the mastery of the student formula is good or bad and directly affect the follow-up study of mathematics.Therefore, the formula teaching occupies a very important position in junior high school mathematics teaching.On the three links in the formula teaching, The derivation of formulas The teaching of mathematical formulas, first of all to enable students to experience the whole process of formula derivation, master the derivation of formulas. In this regard, in the actual teaching, should be targeted
