In the process of preparing lessons, teachers make a teaching aid to better explain the course content to students and guide students to learn independently. PPT usually includes teaching objectives, teaching emphases, difficulties, curriculum design, teaching methods, teaching process, teaching reflection and so on, which can help teachers to organize their ideas more clearly, accurately convey knowledge points and educational concepts, and provide students with a richer and more intuitive learning experience. PPT production of lectures requires teachers to have a clear understanding and grasp of the course content, and at the same time, it is necessary to systematize and visualize their own teaching ideas and methods, so that students can better understand and accept the course content.
