以《天衣无缝》为例浅谈综合实践课在初中数学教学中的实施

On the Implementation of Comprehensive Practice Course in Junior High School Mathematics Teaching

本文为阐明综合实践课在初中数学教学中的具体实施方法和途径,以华师版教材八年级上册77页阅读材料《图形中的"裂缝"》为模型,用综合实践课《天衣无缝》的体例诠释其核心内容,从发现缝儿、研究缝儿、设计缝儿、创造完美的天衣无缝儿四个部分入手,引领学生动手剪拼操作,在实践中不断发现、验证、再发现、再验证,从而引发深入、全面的理性分析和思考,从主观猜测、判断演变为逻辑推理,应用获取的经验完成对问题的探究过程。激发学生的学习兴趣,引导学生学会发现问题并在实践中提升解决问题的能力,感受数学研究的无穷魅力,树立数学学习的信心,在师生的合作交流中激发彼此灵感的火花,充分彰显综合实践课的作用。

In order to clarify the specific implementation methods and ways of comprehensive practice course in junior high school mathematics teaching,this paper takes the reading material Cracks in Figures in the first volume of Grade 8 of the Chinese teachers’edition as the model,and interprets its core content with the style of comprehensive practice course seamless.From the discovery of seams,the study of seams,the design of seams,and the creation of perfect seamless children,students are guided to cut and spell.In practice,continuous discovery,verification,rediscovery and re verification lead to in-depth and comprehensive rational analysis and thinking.From subjective guess and judgment to logical reasoning,the application of the acquired experience completes the inquiry process of problems.Stimulate students’interest in learning,guide students to find problems and improve their ability to solve problems in practice,feel the infinite charm of mathematical research,establish confidence in mathematics learning,stimulate the sparks of mutual inspiration in the cooperation and exchange between teachers and students,and fully demonstrate the role of comprehensive practice course.
