微课是信息技术背景之下悄然兴起的一种有效教学模式。在初中数学教学中,微课的实施与运用,具有很多积极的意义。一方面,微课可以突破教学的重点和难点,达到释疑解惑的教学目的,促进课堂教学效率的提升;另一方面,微课可以增强课堂教学的趣味性,强化概念教学和典型案例的教学,有效地推动初中数学教学的改革和发展。从这些方面我们可以看出,在信息技术背景下,微课教学与初中 Micro-class is an effective teaching mode that quietly arises under the background of information technology. In junior high school mathematics teaching, micro-class implementation and application, has many positive meanings. On the one hand, the micro-class can break through the teaching of the key and difficult to achieve the purpose of teaching doubts and doubts, to promote the efficiency of classroom teaching; the other hand, micro-class can enhance the fun of classroom teaching, teaching and teaching to enhance the typical case , Effectively promote the reform and development of junior high school mathematics teaching. From these aspects we can see that in the context of information technology, micro-class teaching and junior high school
