Khan Academy videos have 700,000,000+ views in English. The website "Netease" has used the CC-BY-NC-SA license to create Chinese Khan Academy videos. This represents an outstanding example of revision of open materials. Over 100 courses and 2,000 specific videos have been translated into Chinese. As stated on the Khan Academy website, "NetEase is the first portal site in China to partner with Khan Academy to localize its content and this greatly enhances NetEase Open Courses' content and user base. Meanwhile, the cooperation with NetEase will promote the localization of Khan Academy courses in China, to achieve the purpose of providing a world class education for anyone anywhere" (https://www.khanacademy.org/about/blog/post/29838569844/netease-subtitles-videos-in-chinese).
This research study will quantify the impact of the revison of the Khan academy videos by exploring (1) the number of times these videos have been watched, (2) classifying which courses have been of greatest interest to viewers, (3) user habits in watching Khan Academy vides (4) comparing the number of views of dubbed videos with subtitled videos, and so forth. We frequently hear that "people don't take advantage of the 5Rs - this study shows that this is not true.
