所谓高效的课堂,就是要求课堂上拥有“足够”科学的教学容量和“适度”的教学节奏;要求能够让学生这个课堂主体的地位得到充分的尊重和发挥;要求教师输出的教学信息能够让学生尽可能多的受益;要求教学的任务和目标能够准时、高效的完成。在初中数学课堂上,影响课堂高效性的因素有很多,如教师的教学行为,学生的学习心智,教材的应用情况等。那么,如何优化课堂教学效率,利用有限的时间创造无限的价值,提高课堂教学效率,让数学课堂焕发生 The so-called efficient classroom, is required in the classroom have “enough ” scientific teaching capacity and “moderate ” teaching rhythm; requires students to be able to make this classroom subject’s position fully respected and play; require teachers to output the teaching Information can benefit students as much as possible; tasks and goals that require teaching can be accomplished on time and efficiently. There are many factors that affect the efficiency of classroom in the junior high school mathematics classroom, such as the teaching behavior of teachers, the students’ study mentality and the application of teaching materials. So, how to optimize the efficiency of classroom teaching, use of limited time to create unlimited value, improve classroom teaching efficiency, make mathematics classroom rejuvenate
