一、背景介绍用方程解决实际问题的基本步骤是“审题、分析、设元、列方程、解方程、检验、作答、反思”.但在以浙教版《数学》七年级上册第五章第4节“一元一次方程的应用(第4课时)”为载体的“多人同课异构”式的教研活动中发现,课堂教学普遍存在分析过程短暂和反思过程缺失的问题,教师也没有留给学生充足的自主思考与实践的时间.这有悖于过程教育和以学为中心的
First, the background introduction The basic steps to solve practical problems with equations are “examining, analyzing, setting yuan, column equations, solving equations, testing, answering, reflections.” But in the Zhejiang edition “Mathematics” seventh grade on the fifth Chapter 4 “The Application of the Unary Equation (Lesson 4)” As a carrier of “multi-person lectures heterogeneous” teaching and research activities found that the classroom teaching ubiquitous analysis process is short and the process of reflection is missing Problem, the teacher did not give students sufficient time for independent thinking and practice. This is contrary to the process of education and learning-centered
