当今,教学仍在分数论英雄的压力下,重“结果”而轻“过程”是教育现状的必然规律。因此,在初中数学课堂上对数学概念的形成过程、定理定律的发现与演绎过程、质疑的释疑过程、解题方法的探究与优化过程、数学思维方法的提炼过程等出现缺失。怎样才能通过教研改进这种教学现状?通过传统教研方式的反思,采用“四阶段”教研方式,就可以有效促进教师观念与行为的良性发展。本文以“一元二次方程”为案例,通过“四阶段”教研方式的基本过程实录,旨在对创新教研形式和提升教师的学科素养有所帮助,也为各位教育同仁提供茶余饭后的教研谈资。 Nowadays, teaching is still under the pressure of fractional heroism, and the “law of results” and the lightness of “process” are the inevitable laws of the current situation of education. Therefore, in the junior middle school math class, the formation process of mathematical concepts, the discovery and deduction of theorem law, the process of doubts and doubts, the exploration and optimization of problem-solving methods and the process of mathematical thinking are lacking. How can we improve the teaching status through teaching and research? Through the reflection of the traditional teaching and research methods and using the teaching and research methods of “four stages”, we can effectively promote the healthy development of teachers’ concepts and behaviors. In this paper, the case of “quadratic quadratic ”, through the “four stages ” teaching and research methods of the basic process of Record, aims to innovate teaching and research forms and to enhance teachers’ academic quality, but also for all education colleagues to provide after-dinner Teaching and Research Talk
