网络画板在初中二次函数教学中的应用研究

Research on the Application of Network Drawing Board in Secondary School Quadratic Function Teaching

二次函数的图像和性质是初中数学学习的重难点,具有极强的综合实用性,对提高学生的数学学科综合分析能力、逻辑思维能力具有较大的帮助。因此,本文针对虚拟教具在初中数学二次函数的应用进行研究,利用网络画板来构造二次函数的图像并观察其图像的变化,探讨二次函数的性质。

The images and properties of quadratic functions are important and difficult points in junior middle school mathematics learning, which has strong comprehensive practicability and is helpful to im-prove students’ comprehensive analysis ability and logical thinking ability of mathematics. Therefore, this paper studies the application of virtual teaching AIDS in junior middle school mathematics quadratic function, uses network drawing board to construct quadratic function and observe the change of quadratic function image, and discusses the properties of quadratic function.
