目前各中小学校都在探讨高效课堂并推出了很多教学模式,然而作为数学老师,是不是应该静下心来想一想:在热热闹闹的课堂背后,我们的课堂是不是高效的?我们是不是过分追求课堂的完美使得如今的数学课千头万绪,“枝繁叶茂却不见树干”?我认为,高效课堂就是以尽可能少的时间、精力和物力投入,取得尽可能好的教学效果,高效课堂就是学生主动学习、积极思考的课堂,是学生充分自主学习的课堂。一、把知识建立在学生的认知基础上 At present, primary and secondary schools are exploring efficient classrooms and introducing many teaching modes. However, as a math teacher, should we stop and think about whether our classrooms are efficient or not behind the bustling classes? Are we not Excessive pursuit of the perfection of the classroom makes today’s mathematics class a multitude of things, However, I think that efficient classroom is to use as little time, energy and material resources to make as good as possible Teaching effectiveness, efficient classroom is the active learning of students, positive thinking of the classroom, students fully self-learning classroom. First, the knowledge based on the students’ cognitive foundation
