文档介绍：几何画板与动态型中考题的整合研究 1 中文摘要随着几何画板在数学解题上的广泛应用,学生在理解动态型题目过程中能轻松将抽象的数学语言转化为具体图像表达,但学生只是看到教师的演示,缺少自己动手操作的过程。本文以全国各省市近三年典型动态型中考试题为例,把题目主要分为旋转、翻折、平移三大类。借助几何画板制作出相应的解题课件,师生能亲自动手操作,从而更好地分析这三类变换的解题特点。本文结合几何画板课件,展现完整的探究过程,让师生在动态中体验这三类变换的变与不变,获得清晰的解题思路。并记录了详细的课件制作步骤,图文并茂, 可作为简易教程供教师参考。关键词:旋转,平移,翻折,几何画板,中考题,动态展示,简易教程 ABSTRACT 几何画板与动态型中考题的整合研究 2 With the Geometer's Sketchpad inmathematics problem solving onawide range ofapplications, the students can eas ily translate the abstract mathematical language into specific image expression inorder tounderstand the dynamic subject process .Butthe students just tosee the teacher's demonstration with the lack oftheir own operation process. Inthis paper asthe various provinces and cities nationwide the typical dynamic type senior high school entrance examination questions inrecent three years for example, the subject ismainly divided into rotation, folding, translation .Using geometric sketchpad toproduce corresponding solving courseware, teachers and students can hands-on operation, thereby better analys these three kinds oftransform exercises. Inthis paper the Geometer's Sketchpad courseware displays afull investigation process, mak ing teachers and students experience the changed and unchanged ofthis three kind of transformations inadynamic type and get aclear thinking. This paper record the detail softhe steps ofmaking courseware illustrat ely. And itcan beused asa simple tutorial for teachers.
