1 MX实验的由来和发展高中数学“目标导学,提高效益”教改实验(简称 MX 实验),已经历了一轮完整的实验阶段(从高一到高三,三年),取得了明显的效果.MX 实验是由初中数学 GX 实验移植,并加以改造实施的.GX 实验的基本指导思想是充分调动学生学习的积极性、主动性,最大限度地提高课堂效益,希望以尽可能少的教学时间取得尽 1 The origin of the MX experiment and the development of high school mathematics “target guidance, improve efficiency” education reform experiment (referred to as MX experiment), has undergone a complete experimental phase (from high one to high three, three years), and achieved significant results The .MX experiment was transplanted and modified by the junior high school mathematics experiment. The basic guiding ideology of the GX experiment is to fully mobilize the enthusiasm and initiative of students’ learning and maximize the effectiveness of the classroom. It is hoped that the teaching will be conducted in as little time as possible. Do all
