The micro-video is mainly the video

The micro-video is mainly the video that the teacher explains the relevant knowledge points under the instruction of the classroom teaching goal, but the micro-video of the high school mathematics rollover classroom can integrate the animation, the geometry sketchpad and so on in the video to let the student abstract the concept. In the process of micro-video recording, we must pay attention to the in-depth analysis of knowledge points, coherent logic is clear, clear, concise and comprehensive. After teaching practice, it is concluded that the time of micro-video recording is usually about 5 minutes. During this time, students'attention is highly concentrated and self-study effect is better, which can enable students to grasp knowledge content more efficiently, expand your cognitive skills. The micro-video promotes students'mastery and understanding of knowledge points in the whole process of inquiry-based classroom, and the micro-video makes students do twice the work with half the effort in the process of pre-class preview because of its vivid, vivid and concise features. Microvideos are not necessarily recorded by the teacher who is teaching them, and if the classroom is flipped over a long period of time, the video producer can be appropriately replaced (for example, teachers in the teaching and research group cross-use each other's microvideos, or use Internet resources) , but teachers should strictly check the quality of video, no matter what style and form of video, should be in line with the learning situation, class situation, teaching content should be closely linked to the teaching objectives, teaching difficulties, can not deviate from, to the left and right. A person recorded video technology, the same style as the long students easily tired, lack of "fresh" , and even lose a certain interest in learning.
