摘要几何画板凭借其优势,成为了教学改革中最重要的工具之一。它在教学改革中影响巨大,它不但使教学结构转化为一种新型的“以学生为主体”的“主导—主体”的教学结构,而且使学生由原来的被动式学习,转变为开放式的自主学习。另外,几何画板在辅助中学数学教学时,有三个设计策略:帮助学生辨析概念;揭示微妙的数形关系;进行变式教学。然而,在运用几何画板时也存在误区和不足。过度使用几何画板;课件制作方面的缺点;教学观念出现偏差。总之,几何画板在中学数学中的改革起着重要作用,教师应当好好利用这一优秀的计算机软件的优势,克服其不足,更好地进行中学数学教学。52380
The Geometer' s Sketchpad becomes the most important tool in teaching reform.In the teaching reform ,the Geometer' s Sketchpad makes enormous influence, reflecting in two aspects. It not only changes the teaching structure into a new kind of ‘student-centered’ called ‘dominant—subject’ teaching structure, but also changes the way students learn,from the the original passive learning into an open self-learning. In addition, while using the Geometer' s Sketchpad in the middle school mathematics teaching, there are three design strategies. Firstly, it helpes students analyze the concepts. Secondly, it reveales the delicate relationship between the number and shape. Thirdly, it conducts variant teaching. However,when using the Geometer's Sketchpad,there are errors and shortcomings. The first one is the excessive use of Geometer's Sketchpad.Also,there are errors in the courseware aspect.The third one is the deviation of the concept of teaching. In short, the Geometer's Sketchpad plays an important role in the middle school mathematics teaching.Therefore,teachers should take advantage of this excellent computer software and overcome its shortcomings to teach mathematics better.
