In the second week, I uploaded a video to explain my ppt. However, with the advancement of the course, I have a new understanding of how to better use PPT for education and found many defects in PPT before. Therefore, I modified my PPT according to the new theory I learned in recent weeks.

The first is the Cognitive Load Theory. I put too much content in a slide before. Moreover, some of these contents do not need to be written in the slide, and it is enough for the speaker to mention them. Then there is the Redundancy Principle. I’m too obsessed with reading the content to the audience. In fact, reasonably letting the audience read the PPT content by themselves will sometimes give them a deeper impression.

Then, the Signaling (or Cueing) Principle in Multimedia Learning. I didn’t highlight the focus of each slide. On the contrary, the illustrations I use are too large and have little to do with my theme, which may make the audience unable to focus on my ppt. So I removed the redundant pictures and used a concise style. In addition, I changed my background to make the content more prominent.

In terms of Dual-coding Theory, I think I do better. In the example sub-link, I explained the text content with pictures of Chinese characters and slides, so as to help the audience understand my theme.

Finally, I changed the font and merged and simplified the content. I believe no one will be interested in PPT with a long text.
