加减法应用题是小学数学一年级的重点教学内容之一。相关教学目标达成的状态是学生能够正确理解加、减法算理并能在各种问题情境中灵活应用相应算理解决实际问题。但在教学过程中教师们不难发现,加减法应用题的问题情境不同,学生的解题正确率也不同。导致此种现象的原因可能有二:其一是,学生对加减法算理的理解仍具有情境的局限性和 Addition and subtraction application questions is the first grade primary school mathematics teaching content. Relevant teaching objectives to achieve the state is that students can correctly understand the addition and subtraction algorithm and can flexibly apply the corresponding arithmetic in various problem situations to solve practical problems. However, during the teaching process, teachers find it easy to find that the problem-solving situations of different application questions are different, and the correct rate of problem-solving is also different among students. There are two possible reasons for this phenomenon: First, students' understanding of the arithmetic of addition and subtraction still has the limitations of context
