Hi Zhihao

Thank you sharing your interesting and impressive blog about Evaluating Multimedia and Tools. I am very agree your point of multimedia is widely used in various fields, but each multimedia has different usefulness, so we should apply some tools to distinguish whether these multimedia are useful to us or not. And after that you clearly introduced SAMR Model and SECTIONS Model and summarized the advantages and disadvantages of these two models, which can help us more in creating teaching and learning contents. Finally, i am wondering if you can tell me more about TPACK framework, that is will be great!
