Hi Mengcheng,

After reading your this week post, I think you gave a good introduction to the three models. Through your introduction, I have a new understanding of these three multimedia teaching models. And you inserted a video for each of the models in your post to show us how the three models work in the field of multimedia teaching, which I think is great.

But I have a suggestion here, I think you can add a comparison of these three models in your post, by summarizing the characteristics and differences of each model, the audience can distinguish the three models as well, and know the differences between the three models. In short, your post is very informative, I hope you can continue to work hard in your future studies. Thanks!
