利用图形计算器的动态几何App,学生可以通过对平面几何图形的各种变换,进行多种尝试,通过学生自己动手操作,发现图形中的“规律”.本文以《中点四边形》这节课为例,通过对课堂教学环节如何依次展开,问题如何提出,学生如何进行实验演示,特别是如何提升到与推理论证水平的探讨等,来描述用HP Prime图形计算器在常态课教学中对学生数学思维品质的培养.
Using the dynamic geometry app of graph calculator, students can make various attempts through various transformations of plane geometric figures and find out the “law ” in the graph by using the students’ own actions. As an example, this paper describes how to use the HP Prime Graphing Calculator in the teaching of normal subjects through the following steps: how to develop the classroom teaching, how to put forward the questions, how to carry out the experimental demonstration of the students, especially how to improve the level of reasoning and argumentation, Cultivating Students’ Thinking Quality in Mathematics.
