In the past, the methods of language teaching mainly focus on the direct method, the grammar-translation, audio-lingual, the structure approach, communicative language teaching, community language learning, task-based language learning, etc. These methods start and develop with the need and application of some theories. At the present time, the computer is widely used in every field and the Internet is compulsory of daily life, especially more and more students use the WeChat APP. So the way of teaching language is changing accordingly. This paper is to analyze the new way of language teaching, the flipped class model, and how it is used with WeChat APP. The first part is the general introduction of the flipped class model, the second part is the application of the flipped class model to reading and writing classes, and the third part is the use of WeChat APP in the cell phone.展开更多

The participants were college students and a total of 255 valid questionnaires were collected. Data was analyzed using descriptive statistics and multiple regression analysis.Findings： Grade level and single-parent family background were found to be significantly correlated with information sharing behaviors whereas no effect of gender was found on information sharing behaviors. Dating status had no significant impact on user browsing behavior, but was related to users＇ publishing posts and posting replies.Implications： The study will help understand individual differences in information sharing among WeChat users.Limitations： First, the relatively small sample size is a limitation in exploring the effects of demographic variables on user information sharing behaviors. Second, this study only used questionnaire surveys to collect data and more research methods such as interviews should be adopted to improve the accuracy of the study results.Originality/value： This paper is one of the first studies to explore the relationship between demographic variables and user information sharing behaviors on WeChat.展开更多
