2014年中考已经落下帷幕,静下心来认真审视试卷,揣摩命题者的意图,全面总结、归纳学生的答案,分析答卷时出现的问题,提出合理化教学建议.以2014年河北省中考数学第25题为例,进一步赏析与反思.此题以“圆与轴对称变换”为载体,以“分类讨论、数形结合”等数学思想方法为依托,以“综合运用数学知识分析和解决问题”的能力为立意,考查学生在灵活运用知识和方法的过程中,表现出来的学习数学的潜能和思维能力.
In 2014, the senior high school entrance examination has come to a close, trying to carefully examine the papers, try to figure out the intention of the proponents, comprehensively summarize and summarize the students’ answers, analyze the problems that arise when answering the questionnaires, and put forward the reasonable teaching suggestions. As an example, further appreciation and reflection.This question is based on “circle and axisymmetric transformation ” as the carrier, relying on mathematical classification and discussion, number combination and other mathematical thinking and methods, with “comprehensive analysis of mathematical knowledge and Problem-solving ”as a conception, examining students’ potential and thinking ability in learning mathematics in the process of applying knowledge and method flexibly.
