《数学课程标准》明确指出:“对数学学习的评价要关注学生的学习结果,更要关注他们的学习过程。”在教学实践中,我发觉一种能体现学生学习过程和方法的载体就是草稿纸的使用。因为草稿的价值就在于表现学生掌握一些技能所经历的探索、猜想、推理等过程。小学生使用草稿本情况分析现象一:心稿多,草稿少。低年级计算主要是百以内的加、减或表内乘除法。大部分学生可以根据心算就能够解决数学问题。而到了中高年级,随着知
The standard of mathematics curriculum clearly states: “In the evaluation of mathematics learning, we should pay attention to the learning outcomes of students and pay more attention to their learning process.” In teaching practice, I found a carrier that reflects the learning process and method of students Is the use of scratch paper. Because the value of the drafts lies in the process of exploring, guessing, reasoning and the like experienced by students in mastering some skills. Primary school students using the draft situation analysis Phenomenon 1: Heart manuscripts, draft less. The calculation of the lower grade is mainly within one hundred plus, minus or table multiplication and division. Most students can solve math problems based on their mental arithmetic. And to the senior, with the knowledge
