Viewed from the Report of the Eighteenth Party Congress about the education proposed the idea of deepening the reform of education field, focusing on improving the quality of education, and cultivating students' innovative spirit, and the “Long-term Education Reform and Development Plan (2010-2020)” proposed the suggestion about education of the next decade on continuing education, building lifelong learning "overpass" as well as a flexible and open system of lifelong education. We should pay a high attention to the teaching mode reform. In the new period, with the rapid development of network technology, the massive influx of cloud computing, curtain lessons and cooperative learning inject fresh blood to modern distance education. And they also bring more selections to distance education teaching mode. Teacher's role should go down from the "altar", and turn from the "monologue" to "listen". The students are no longer a passive acceptance of learning. They should think actively and learn with questions. Only in this way, they could really become "learning talent". Based on this concept, collaborative learning model came into being and has been developing rapidly.
