一、立足迁移加强联系在教学中应充分利用知识迁移规律,促使学生在理解掌握的基础上,构建数学模型。教材中例1本身就是一道需要两步计算的实际问题,但教材的编写意图是通过贴近学生的生活情境教学列出综合算式并进行脱式计算,概括加减混合运算的计算法则。但由于学生在问题解决中,进行数学分析的习惯还没有建立,很多学生不大经大脑周密思维就想当然地列式。故教学中还应从分析入手,培养学生按事
First, based on the relocation to strengthen contact In the teaching should make full use of the law of knowledge transfer, prompting students to understand and master the foundation to build a mathematical model. Example 1 in the textbook itself is a practical problem that requires two-step calculation. However, the teaching material is intended to be written in a way that is close to the student’s life situation and summarizes the calculation rules for adding and subtracting mixed operations. However, due to the students in the problem-solving, the mathematical analysis of the habit has not been established, many students are not the brain thoughtful formula to take it for granted. Therefore, teaching should start from the analysis, training students according to the affair
