新的教学理念下,教学改革在有序推进,广大教师积极探索教学模式,但是,课堂教学依然存在着低效和无效现象。因此,高效课堂教学理念应运而生。而高效课堂教学离不开教学情景的创设。在数学课堂教学中,教师都在煞费苦心,创造性地设计一些教学情境,特别是公开课、研讨课中,教学情境已必不可少。但笔者认为教学情境必须要为提高课堂的有效性而设计,我们不能为创设情境而创设情境,不能只图课堂的形式的丰富多彩而影响课堂的内容。
Under the new teaching philosophy, the teaching reform progressed in an orderly manner, and the vast majority of teachers actively explored teaching modes. However, inefficient and ineffective teaching still exists in classroom teaching. Therefore, the concept of efficient classroom teaching came into being. Efficient classroom teaching can not be separated from the creation of teaching situations. In mathematics classroom teaching, teachers are painstakingly creative design of some teaching situations, especially in open class, seminar, teaching situation is essential. However, I believe that the teaching situation must be designed to improve the effectiveness of the classroom. We can not create situations for the creation of contexts. We can not only influence the content of the classroom through the rich and colorful forms of the classrooms.
