一、背景介绍“课标”根据数学具有过程和结果的二重性特征,倡导统筹兼顾过程与结果,以全面发挥数学的育人功能.但在以浙教版《数学》八年级下册第二章第2节“一元二次方程的解法(第2课时)”为载体的“多人同课异构”式的研修活动中发现,课堂教学普遍存在过程教育不到位的问题.网上查阅同类课例发现也有类似现象.鉴于此,笔者在重复式观课与反思基础上,对该课的教学进行重建,改进后的教学过程与效果得到了同 I. Introduction Background According to the dual character of process and result, mathematics advocates the overall process and result, in order to give full play to the educational function of mathematics.But in the eighth edition Chapter 2 Section 2 “solution of a quadratic equation (second class) ” as a carrier “multiplayer heterogeneous ” type of training activities found in the classroom teaching ubiquitous process of education is not in place .While the same kind of cases were found online, there was a similar phenomenon.In view of this, on the basis of repetitive observation and reflection, the author reconstructed the teaching of the lesson and improved the teaching process and effect
