Abstract
In this paper, we proposed a scaffolded writing and rewriting model which combined 4 kinds of activities: reading, creating, talking, and revising (RCTR). This scaffolded writing and rewriting process provides students plenty of various inspirational guidance in writing process. Based on this model, we developed a game-based writing environment, called Creation-Island (CI). Specifically, the CI provides peer feedbacks prompts which could scaffold their writing skills in rewriting process. Next, we will examine the effect of CI with RCTR model in improving students' writing ability and interest in a primary school.
