函数反映了客观世界中的运动变化和数量关系,它在科研、生产和社会生活中有着极其广泛的应用。函数问题在数学领域占据了极其重要的位置,初中阶段主要学习一次函数、二次函数、反比例函数等内容,学生通过深入剖析,将函数与方程、不等式等内容建立联系,运用数形结合的思想分析与函数相关的实际问题,从而提高解决实际问题的能力。《基础教育课程改革纲要》指出:“在课程的实施过程中,加强信息技术教育,培养学生利用信息技术的意识和能力。”在函数教学中引入信息技术,能弥补传统课堂教学的不足,提供师生之间、学生之间信息交
Function reflects the changes in the objective world and the quantitative relationship, it has a very wide range of applications in scientific research, production and social life. Function problems occupy an extremely important position in the field of mathematics. In the junior middle school, students mainly learn primary functions, quadratic functions and inverse proportion functions. Through in-depth analysis, students relate the functions to equations and inequalities, Analyze practical problems related to functions and improve their ability to solve practical problems. The Essentials of Curriculum Reform in Elementary Education states: “In the process of curriculum implementation, we should strengthen information technology education and cultivate students’ awareness and ability to use information technology.” Introducing information technology into function teaching can make up for the deficiency of traditional classroom teaching , To provide information between teachers and students, students information exchange
