综观近几年的中考试卷,出现了不少在平面直角坐标系中探索平行四边形顶点坐标的问题,而此类问题源于教材的习题,体现了教材习题具有一定的典型性和探索性,有拓展、开发和挖掘的空间.因此,在中考复习过程中,要加强对教材习题的研究,不断地挖掘习题的内在潜能,将习题进行有效的串联,从而展示知识的发生、发展过程,启迪学生思考、顿悟、探求,有效地帮助学生提高复习的效率,增强学生综合应用知识的能力,使他们学会探索、学会创造. Looking at the examination papers in recent years, there have been many problems in exploring the coordinates of the parallelogram vertices in the Cartesian coordinate system. However, these problems originate from the textbook exercises, which show that the textbook exercises are typical and exploratory. Expand, develop and excavate space.Therefore, in the process of exam review, we should strengthen the study of textbook exercises, continue to tap the inherent potential of exercises, the exercises in an effective series, so as to demonstrate the occurrence of knowledge, the development process, inspire students Thinking, epiphany, exploration, and effectively help students improve the efficiency of review and enhance students’ ability to apply knowledge comprehensively so that they can learn to explore and learn to create.
