Hello Yiran,
Very start to read your blog, our topics are similar, both about SAMR model. By reading your blog, I found something that I had missed before. I saw your article that you used this model in writing your paper, something I had never thought of before, and you said that the SAMR model was also used in your English class. I think after reading your article, I understand more about what SAMR model is. Your article is very logical and uses videos as an aid to explain and better help the reader understand the content of the article.
