高效课堂是提升数学课堂教学质量、深化数学课改的重要途径之一,而良好的师生互动是打造高效课堂的重要因素。一直以来我们对教学互动的认知和理解都过于片面:只要课堂气氛活跃,学生完全跟着教师设计的思路走,就是良好的教学互动。其实,这样的课堂教学多以教师为中心,过分强调教师的教,忽视了学生的学,本质上是一种伪互动。法国著名思想家卢梭曾说:“最重要的教育原则是不要爱惜时间,要浪费时间,即学生必须有充裕的时间体验和沉思,才能自由地发展其心智与能力。”一堂高效的数学课,从课题引入到抛出问题,再到解决问题,整个师生互动的过程中,教师仅仅是一名引领者,学生才是课堂的主体。 Efficient classroom is one of the important ways to improve mathematics classroom teaching and deepen mathematics curriculum reform. Good interaction between teachers and students is an important factor for building efficient classroom. Our understanding and understanding of teaching interaction has always been one-sided: as long as the classroom atmosphere is active, students follow the teacher’s design idea completely and are good teaching and interaction. In fact, such classroom teaching is mostly teacher-centered, overemphasizing teachers ’teaching and neglecting students’ learning is essentially a pseudo-interaction. Rousseau, a famous French thinker, once said: “The most important principle of education is not to cherish time, to waste time, that is, students must have plenty of time to experience and meditate before they can develop their mind and ability freely.” An Effective Math Lesson , From the introduction of the subject to the issue of throwing, and then to solve the problem, the entire process of teacher-student interaction, the teacher is just a leader, the student is the main body of the class.
