1、3中心对称一、学生起点分析学生的知识技能基础：在七年级（下）和本章前面几节课中，已学习了轴对称、平移、旋转等概念，学生已充分理解了各种变换的基本性质，具备了分析、设计图案的基本技能。学生活动经验基础：在相关知识的学习过程中，学生已经初步积累了一定的图形变换的数学活动经验，本节课旨在让学生在进行观察、分析、欣赏等操作性活动中，丰富学生对图形变换的认识，并使他们正确理解和把握平移、旋转等内容，进一步深化对图形的三种基本变换的理解和认识。二、学习任务分析（一）知识与技能：1认识中心对称的概念。2能综合运用变换解决有关问题。（二）过程与方法1通过观察、探索等过程，使学生更深刻地理解轴对称、平移、旋转及
2、组合等几何变换的规律和特征，并体会图形之间的变换关系。2运用讨论交流等方式，让学生自己探索出图形变化的过程，发展学生的图形分析能力、化归意识和综合运用变换解决有关问题的能力。（三）情感、态度与价值观1通过组织学生讨论交流，增强学生的合作意识。2通过经历观察、分析、操作、概括、探索、归纳等过程，进一步发展学生的空间观念，增强学生的审美意识。3通过图形间的变换关系，使学生认识到一切事物的变化可以通过一系列基本变化的组合得到，体会事物从量变到质变的过程。4通过发展学生综合运用变换解决有关问题的能力，使学生对人生观和价值观有更深刻的认识：只有充分认识世界才能改造世界。三、教学过程设计本节课设计了六个教
3、学环节：第一环节：游戏及图片欣赏；第二环节：复习旧知，引入新课；第三环节：合作交流，解决问题；第四环节：练习与提高；第五环节：课堂小结；第六环节：布置作业第一环节游戏及图片欣赏活动内容：活动目的：通过观察发现两幅图形的内在关系，这个活动为课堂提供了极好的素材，也将极大地激发了学生学习的积极性与主动性。第二环节复习旧知，引入新课内容：通过以上观察，理解中心对称的概念效果：通过学生找到上图的对称关系，运用讨论交流等方式，让学生自己探索出图形变化的过程，为后面寻找组合图形所运用的几何变换的规律和特征奠定了基础。第三环节：合作交流，解决问题内容 1：中心对称与轴对称的联系与区别A B C C 1 A
