An Exploration on the Teaching Practice of "Preliminary Geometry" with NetPad——A Case Study of Class A, Grade 7, Fengtai Middle School, Beijing National Day School

In order to adapt the development trend of education informatization, academician Zhang Jingzhong Chinese Academy Sciences led his team develop China's first professional mobile Internet dynamic mathematics software on basis Supersketchpad, named NetPad, which is mainly used serve science teaching. This paper takes students Fengtai Middle School Beijing National Day as experimental objects, and uses research methods such questionnaire survey test collect main data process. Two classes were randomly selected participate in teaching experiment. The results show that n NetPad assisted junior middle school "figures geometry" can better mobilize students' interest mathematics, improve understanding ability plane geometry, their spatial imagination ability, exercise thinking master good learning methods, "figure problem solving achieve grades results.
