After reading <Defining OER-Enabled Pedagogy>, I found that there are 5R activities: Retain、Reuse、Revise、Remix and Redistribute. This unique advantage of open education allows students to re-evaluate their own work, completion, and so on. He can give students maximum creative freedom and create their own way of learning and thinking. Students are often able to show a stronger sense of being a student, which is incomparable to traditional education. For example, in our traditional education, we finish homework, but we have a better idea, at this time we are often difficult to modify, so open education is so flexible. At the end of the article, the author mentioned that the initial investment cost of open education is more than that of traditional education. As a businessman, I think it is an investment. Zero to one is often the hardest of all things, but once the development is complete, the subsequent costs gradually decrease. Finally, you will make a profit.
