The Research On Social Annotation Based On Knowledge Building

Social annotation is a reading style that mutual dialogues are between readers, text and other readers in the form of annotation. The annotation tools not only provide the space for sharing and exchanging after reading but also extend the reading content. Then the functions of social annotation are analyzed in the perspective of knowledge building, with the annotation scaffolds to enhance the role that promote the continuous improvement of the view and build the collective knowledge. And the corresponding application models are designed to provide a new way for promoting students’reading.Firstly, the content of knowledge building, social annotation and learning scaffoldings was systematically carded and the social annotation platforms and made a comparison of their functions, choosing the suitable platform for this research. Then the functions of social annotation are analyzed in the perspective of knowledge building, with the analysis of the necessity of learning scaffoldings in the process of knowledge building. Based on the frameworks of foreign reading assessment and the domestic requirements of reading ability, the corresponding reading annotation scaffoldings are designed. Finally, the research is taken Class four Grade eight of fraternal and experimental school in Minhang District as a case, designing and implementing the experiment of social annotation based on knowledge building.The results show that with annotation scaffoldings, social annotation can mobilize students’existing knowledge experience, reconstruct and integrate their own knowledge with others’, deepen the understanding of the reading contents and encourage students actively to build and enrich their personal knowledge and collective knowledge.
