Design And Applied Research Of Micro-lecture In Mathematics Primary School

With the rapid development of the information and technology, many kinds of micro-resources have appeared in people's life. Micro-lecture as a new micro-resource also has gradually joined to the education field. It has pivotal effect on the revolution of teaching and learning. It compared the outstanding works of micro-lectures in mathematics lessons, and summarized the characteristics of good micro-lectures in elementary school mathematics lessons. This paper mainly researched strategies of teaching design in micro-lectures in elementary school mathematics lessons. And it summarized three principles of micro-lectures design:tiny, interaction, and refinement. It studied the principle of topic selection in micro-lectures in elementary school mathematics lessons, and fine design of micro-lectures in elementary school mathematics lessons. Including micro principle refers to the "micro" to select teaching content and teaching contents of "micro";Interactive principle emphasizes the design of the interactive problem should from the perspective of learners in combination with real-life problems and according to the student to carry on the design, the zone of proximal development design should pay attention to the problem of gradation and graduality. Secondly also should pay attention to the design of interactive technology, such as the head of the teachers,setting of sound, rhythm, the design of the network communication platform, etc. Fine principles embodied in a target, the four parts of the two processes, in the design of teaching content. Micro course design and development of the combination of paper works to know of the circle. It discussed the design of teaching model, and the design and implementation of strategies of the tests of before and after class based on the flipped classroom in elementary school mathematics lessons.
