微课是近年来一种新兴的学习资源,是将不同教学资源通过视频这一载体应用到某个知识点或教学环节的教学活动中。将微课应用到小学数学教学中能够充分调动学生的学习兴趣,获得预期的教学效果。这正符合新课程改革的理念与要求。因此,数学教师在设计微课时应合理开发和利用数学教材资源,通过对微课的运用来提高小学数学课堂的有效性。 Micro-class is a new learning resource in recent years, which is to apply different teaching resources to the teaching activities of a certain knowledge point or teaching through the carrier of video. The application of micro-class to primary school mathematics teaching can fully mobilize students’ interest in learning and obtain the expected teaching effect. This is in line with the concept and requirements of the new curriculum reform. Therefore, mathematics teachers in the design of micro-class should be reasonable development and utilization of mathematics teaching resources, through the use of micro-class to improve the effectiveness of primary school mathematics classroom.
