“用二分法求方程的近似解”是人教A版《数学1》(必修)第三章的主要内容。笔者以此尝试开展了“磨课”教学探索。笔者通过与同行一起研究学生、研究课堂、研究教材、研究教师间的合作探究等,感受“磨课”带来的教学观念转变和教学能力的提升。1教师准备(1)谨慎筛选磨课内容。所选内容知识点相对独立,难度比较恰当,能让教师充分展示教学智慧,有利于学生思维发展。“用二分法求方程的近似解”是《普
“Use the dichotomy to find the approximate solution of the equation ” is the main content of the third chapter of the chapter A of mathematics 1 (compulsory) for people to teach. In this attempt, the author has carried out the teaching of “grinding lessons”. Through researching students, researching classrooms, studying teaching materials and researching cooperation among teachers, the author feels that the concept of teaching and the improvement of teaching ability brought by the “grinding class” can be improved. 1 teacher preparation (1) carefully screening course content. Selected knowledge points relatively independent, more appropriate difficulty, allowing teachers to fully demonstrate the teaching wisdom, is conducive to the development of student thinking. “Use the dichotomy to find the approximate solution of the equation ” yes "Pu
