However, due to the drawbacks in traditional teaching of English writing, especially the lack of effective information input （EII）, it is not an easy task for students to improve their writing level in conventional classes. This paper focuses on the study on group work from the perspective of information input. Unlike previous research, this paper intends to demonstrate the role of group work in obtaining effective information input. It starts with a brief introduction to problems in traditional teaching of English. Then it states the definition of group work and the ZPD theory applied in the paper. In the third part, it proposes a case study to testify how group work may improve the effective information input and terminate the study with the conclusion that group work can help to enhance students＇ effective information input. Based on the results of the study, we may suggest that applying group work in an English writing class will finally help students to elevate their writing level.展开更多
