This book introduces the Design-Based Research (DBR) methodology to develop a pedagogy named Wiki-based Collaborative Process Writing Pedagogy (WCPWP). Through this, teachers can enrich their teaching knowledge and orchestrate collaborative writing activities by using Wiki to help primary school students with their Chinese writing.The results of this study have theoretical implications for applying Technological, Pedagogical, and Content Knowledge (TPACK) framework and design principles for implementing Wiki-based collaborative process writing in the Chinese context. It is an example of capitalizing on computer and Wiki technologies to support collaborative writing among upper primary school students in Mainland China.
