Chapter 2, it introduces the basic cerebration and methods of mathematics, listing the gradually used basic cerebration and methods in secondary-school teaching, and then sorts them out, by simply explaining the sample problems, to make the readers especially the worker including me understand the theory generally.

第二章介绍了数学基本思想方法，列举了中学数学教学中常用的数学基本思想方法，并对此进行了分类，又通过例题加以简单地讲解，使读者，特别是包括作者本人在内的从事数学教育的工作者对中学数学基本思想方法有了全面的认识。

And try to define it in the following aspects: I By using the characteristics of computer hyper text, carry out the combination of information techniques and math courses; II Use the modern information techniques as a basic tool for students in vocational schools to gain knowledge; III The combination of modern information technique and content of math course should face the students' cognizable structure. IV To develop interest is the ultimate purpose of this combination; There are explanations of typical cases and discs of courseware in this thesis. From the cases, we can found that the combination is feasible in some content. In order to put the theory into practice, this academic thesis also presents some questions worthy of further thought.

对"信息技术与职教数学课程整合"进行了界定，重点在以下方面进行了探索和实践：、利用计算机超文本特性，实现信息技术与数学课程内容整合、把现代信息技术作为职业学校学生的基本认知工具、根据职校学生的认知特点进行现代信息技术与数学课程内容整合、整合将大大激发学生学习数学的兴趣文中附有典型的案例说明及课件光盘，从案例可以看出，"信息技术与职教数学课程整合"具有一定的可行性；为了更好的将理论运用于实践，本文还提出了值得思考的问题。
