Hi Qiaoyang,
Thank you for sharing your post! I like your understanding of Merrill’s principles and it helped me to understand the concept. You have mentioned a good point of explaining Merrill’s principles in your blog, which is learners need to be motivated and curious before they could actively conduct the learning process.
I think your chemistry course design is very interesting. Learning chemistry through watching animated videos is a really good way to learning and the use of videos or photos can be effective in helping students to enhance their memory.
