Abstract
This paper proposed a mutual teaching model for assisting students in writing compositions, and implemented a writing aid system as a Web application based on the model where students, teachers and our system teach each other their knowledge of writing. We designed the system to use in first language writing courses in the university. The existing systems have two problems: (a) the limitation of assistance for structure or contents of composition, (b) few mechanisms that allow teachers to incorporate their educational objectives into systems. In our proposed model, a student annotates on his/her own composition and makes comments on other’s compositions. And teachers define “Composition Rules” for incorporating their educational objectives into systems. Using the rules and results of the annotation, our system provides various assistance for also structure or contents of composition. By the proposed model and a coventional model, we made two composition experiments whose results showed the effectiveness of the proposed model and “Composition Rules”.
