“从问题到方程”是苏科版教科书七年级《一元一次方程》中的第一节.方程源于解决实际问题的需要,教科书设计本节的目的,是试图通过对实际问题中的数量关系的分析,引导学生建立一元一次方程,让学生初步感受方程是刻画现实世界的有效的数学模型.作为“一元一次方程”的起始课,如何让学生感受“从问题到方程”的过程,感受这个过程中的重点、关键及注意事项呢?笔者发现,大多数教师在设计该课的教学时,除了完成教 “From Problem to Equation ” is the first section of the “Coefficients Equation” in the seventh grade of the Suke textbook. The equation stems from the need to solve practical problems. The purpose of this section of the textbook design is to try to solve the practical problems Quantitative relationship analysis, guide students to establish a one-time equation, let the students feel the equation is an effective mathematical model of the real world.As the “one dollar equation ” starting class, how to make students feel “from the problem to the equation ”Process, feel the focus of this process, the key and precautions? I found that most teachers in the design of the teaching of the lesson, in addition to completing the teaching
