近年来,随着新课程制度的不断改革,数学课堂变得越来越丰富,多媒体教学设备的应用也越来越普遍,但在当前的数学教学过程中,还存在一些尚待解决的问题,因此我们必须明确问题产生的原因,从而打造高效数学课堂。在数学课堂上,营造良好的教学氛围是比较重要的。1开放式教学的含义所谓开放式教学,是依据基础教学理论,掌握学生实际学习中的难点和问题,进而实现课堂讲授内容、方式以及思路的合理规划的教学模式。通过应用 In recent years, with the continuous reform of the new curriculum system, mathematics classrooms have become more and more rich, and the application of multimedia teaching equipment has become more and more common. However, there are still some unsolved problems in the current mathematics teaching process, Therefore, we must clarify the cause of the problem, so as to create an efficient math class. In mathematics classroom, to create a good teaching atmosphere is more important. 1 The Meaning of Open Teaching The so-called open-ended teaching is based on the basic teaching theory, master the difficulties and problems in the actual student learning, and then to achieve the classroom teaching content, methods and ideas of the rational planning of teaching mode.
