几何与运动型问题能让学生经历观察—操作—实验—猜想—验证的探究过程不仅能考查学生的空间观念,对图形的认识,图形的变换,图形的设计,图形的直觉判断能力,而且还能考查学生的分析综合和抽象概括逻辑推理能力,是学生展示个体思维发散创新的好平台。几何与运动型问题在近几年各地中考试题中常以压轴题的形式出现,它能考查学生的多种能力,有较强的选拔功能。下面笔者利用三类经典图形运动问题帮助学生解决难点问题。
Geometry and sports problems allow students to observe - Operation - Experiment - Conjecture - Verification of the inquiry process can not only examine the student’s space concept, understanding of graphics, graphics transform, graphics design, intuitive graphics ability to judge, but also Students can analyze the comprehensive analysis and abstract logical reasoning abilities, is a good platform for students to demonstrate individual thinking divergent and innovative. Geometry and sports problems in recent years around the exam questions often appear in the form of finale, it can examine the students’ multiple abilities, there is a strong selection function. Here I use the three classic graphics exercise to help students solve difficult problems.
