The link to Jacy’s blog.

First of all, I really like the TED video which you choose. It is a nice topic. Meanwhile, your analysis of the TED video is nice and in detail. You point the advantage and disadvantages of the video and explain your idea. You have an excellent understanding of the multimedia learning principle and cognitive coding theory. Finally, I wonder if maybe you could improve your analysis of dual coding theory. For example, gives more explanation about why it does not meet the criteria.

Overall, your blog is very nice and I really like it.
