The first step is to use PowerPoint20 10 to make video courseware. Of course, in addition to PowerPoint, this operation can also be realized through Focusky, which is basically similar to PPT, and finally it only needs to be saved in video format.
The second step is to record a video of a real person explaining the green screen background, that is, to record a video of himself explaining the courseware under the green screen background, and then you can directly use the green screen keying function of the color editing master to cut the picture.
The third step is to import the micro-lesson video and the real-life video into the multi-color editing master, remove the green screen background, and then move the characters below the micro-lesson video to make a vivid and interesting real-life micro-lesson video.
Micro-course refers to a structured digital resource that uses information technology to present fragmented learning contents, processes and extended materials according to cognitive rules. The core content of "micro-lesson" is classroom teaching video (lesson fragments), and it also includes auxiliary teaching resources related to teaching themes, such as teaching design, material courseware, teaching reflection, practice test, student feedback, teacher comments and so on.
They create a semi-structured, thematic resource unit application "microenvironment", which has a certain organizational relationship and presentation mode. Therefore, "micro-course" is not only different from traditional teaching resources such as teaching examples, teaching courseware, teaching design and teaching reflection, but also a new teaching resource inherited and developed on this basis.
Micro-course only teaches one or two knowledge points, without complicated curriculum system and numerous teaching objectives and teaching objects. It seems that it is not systematic and comprehensive enough, and many people call it "fragmentation". However, micro-courses are aimed at specific target groups and deliver specific knowledge content. A micro-course itself should be systematic, and the knowledge expressed by a group of micro-courses should be comprehensive.
