【摘要】：几何学科是研究数量关系和空间形式的科学，学习几何对学生的发现问题能力、解决问题能力、逻辑思维、抽象思维都有着十分重要的作用。几何学科在学生的学习生涯中都是不可或缺的，所以学习几何的程度，直接影响着学生的发展。几何学科在初中数学中有着比较特殊的地位，它是一门图像比较多的学科，绝大部分知识都跟图形有着密切的联系，所以对学生的逻辑思维和抽象思维有着很高的要求。但是，传统的教育方式很难培养学生的逻辑思维和抽象思维，很多传统的教学都是教师直接传授知识，没有让学生的思维得到充分的锻炼。因此我们就需要一个适合学生的学习方式-探究学习。同时，在传统的教学方式中，会遇到各种各样的困难。例如在画一个图形时，教师为了节约时间，往往在黑板上只会画少量的图形，学生如果不会举一反三的话，，学习起来便会很吃力；例如要验证一个动点问题时，不可能把所有的位置都展示给学生。但是通过信息技术及网络工具可以很容易做到这些。本文根据初中学生的发展方向，同时结合初中几何学习特点，在初中几何教学中运用了探究学习的方式，从而培养学生的分析问题、解决问题的能力，并且进一步提高学生的逻辑思维、抽象思维。首先对于本课题的背景、意义、现状及研究内容进行了论证。其次对于建构主义、探究学习的理论基础进行了研究及讨论。并通过对初中几何课程标准来判断学习中的重难点进行了分析。然后对于几何学科的知识点进行了分析，将知识点的内容加以分类整理，并设计相应的支持方式。通过对各种模块的分析，设计了初中几何探究学习平台。最后通过实际的教学案例对学生进行实践研究。从实践研究中得出结论：初中几何探究学习平台可以很好的支持教师的授课及学生的学习。
[Abstract]:Geometry is the science of studying quantitative relations and spatial forms. Learning geometry plays a very important role in students' ability to discover problems, to solve problems, to think logically, and to think abstractly. Geometry is indispensable in the study career of students, so the degree of learning geometry directly affects the development of students. Geometry has a special position in junior high school mathematics, it is a subject with more images, most of the knowledge is closely related to graphics, so there is a high demand for students' logical thinking and abstract thinking. However, it is difficult to train students' logical thinking and abstract thinking in the traditional way of education. Many traditional teaching methods are teachers to impart knowledge directly, and the students' thinking has not been fully trained. Therefore, we need a suitable learning style for students-inquiry learning. At the same time, in the traditional teaching methods, there will be a variety of difficulties. For example, in drawing a graph, in order to save time, teachers often only draw a small number of graphics on the blackboard, if students can not cite three words, it will be very difficult to learn; For example, to verify a dynamic point problem, it is not possible to present all the positions to the student. But it is easy to do this through information technology and network tools. According to the development direction of junior middle school students and the characteristics of geometry learning in junior middle school, this paper applies the way of inquiry learning in geometry teaching of junior middle school, so as to cultivate the students' ability of analyzing and solving problems. And further improve students' logical thinking, abstract thinking. First of all, the background, significance, current situation and research contents of this topic are demonstrated. Secondly, the theoretical basis of constructivism and inquiry learning is studied and discussed. And through to the junior middle school geometry curriculum standard to judge the important difficulty in the study to carry on the analysis. Then the knowledge points of geometry are analyzed, the contents of knowledge points are classified and sorted, and the corresponding supporting methods are designed. Through the analysis of various modules, the junior high school geometry inquiry learning platform is designed. Finally, through the actual teaching cases to carry on the practice research to the student. The conclusion is drawn from the practical research: junior high school geometry inquiry learning platform can support teachers' teaching and students' learning.
