Hi,Kaining
After reading your blog, I agree with what you said about spatial and temporal contiguity. In the future, when I do my PPT, I will put the relevant words and images on the same page instead of separate pages, so that my readers can better understand my content. Another point, I think the same as you. I also think that the reason why experts can’t follow all the principles is that they are specific to each specific situation. If an expert adopts all kinds of media, there will be many kinds of media, which will bring more burden.

Thanks for sharing.
