《义务教育数学课程标准》(2011年)中明确指出:“要利用信息技术有效地改进教与学的方式,使学生乐意并有可能投入到现实的、探索性的数学活动中”。在初中数学教学中,对数学直观性背景的创设和数学探究发现过程的展示较少,学生靠想象去理解,存在理解能力、探究能力薄弱的现象。恰当使用信息技术,可以改善学生的学习方式,特别是“几何画板”的强大功能,更能优化数学教学,它能使静态的图形动态化,抽象的概念形象化,枯燥、零散的知识体系
The standard of compulsory education mathematics curriculum (2011) clearly states: “To make effective use of information technology to improve the teaching and learning methods so that students are willing and possible to invest in realistic and exploratory mathematical activities.” In junior high school mathematics teaching, there are few demonstrations on the establishment of mathematical intuitionistic background and discovery process of mathematical inquiry, students’ understanding by imagination, existence of understanding ability and weak inquiry ability. Proper use of information technology can improve students’ learning styles, especially the powerful functions of “geometric drawing board”, and can further optimize mathematics teaching. It can make static graphic dynamic, abstract concept visualization, boring and fragmented knowledge system
