This paper takes typical teacher’ workshop as an example to do experiments. The results show that learners can discuss around the theme of training; Compared to ordinary learners, excellent learners are more active in their learning attitude; for example, they have deeper understanding in multimedia and Micro-lecture technology application; however, the topic of “summary and review of technical support” and “teaching evaluation of technical support” did not appear.
