高效课堂之所以成为新课程以来的一个老生常谈的话题,是因为大部分教师的教学方法还比较欠缺,课堂效率还有待提高。所以,广大教师仍要更新教育教学观念,要立足于物理教材,找准教学目标,采用多样化的教学手段,以保证每节课45分钟的效率。因此,如何构建高效的物理课堂,如何调动学生的学习兴趣就成为物理教师亟须解决的问题。 The reason why Efficient Classroom has become a common topic since the new curriculum is that most teachers’ teaching methods are still relatively scarce and classroom efficiency needs to be improved. Therefore, the majority of teachers still want to update the concept of education and teaching, we must base ourselves on the physical teaching materials, identify the teaching objectives, using a variety of teaching methods to ensure the efficiency of 45 minutes per class. Therefore, how to construct an efficient physics classroom and how to arouse students’ interest in learning has become an urgent problem to be solved by physics teachers.
