高效课堂的高效不在于教师一节课讲了多少内容,而是通过教师的引领和学生积极主动的学习,在单位时间内高效、高质量地完成教学任务,促进学生获得高效发展。也就是说,高效课堂不仅要注重在“量”上的提升,更重要的是注重在“质”上的提升,高效课堂教学的“高效”性就是通过课堂教学活动,学生在学业上有超长的收获,超长的提高。因此,研究高中数学课堂 Efficient classroom efficiency is not about how much a teacher talked about the content, but through the guidance of teachers and students take the initiative to learn, the unit time efficient and high quality to complete the teaching tasks and promote efficient development of students. In other words, efficient classroom should not only pay attention to the promotion of “quantity ”, more importantly, focus on the “quality” of the promotion, efficient classroom teaching “efficiency ” is through classroom teaching activities, Students in the academic long-term gains, long-term improvement. Therefore, research high school mathematics classroom
