Long-tested pedagogical theories can provide the basis to analyze and interpret students' interactions in distance learning environments. Through this lens, useful conclusions can be drawn from students' data that could help to improve the teaching and learning process. In this paper, a number of forum posts were analyzed and the role of tutors and students was scrutinized through the use of network visualization. It was found that certain students have a central positive role in the discussion forum although tutors have the main burden of answering and keeping the interaction alive. These students can act as the more knowledgeable other and support their peers. Further research in order to gain insight into students' interaction and promote collaboration, is proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
