The aim of this exploratory study is to analyse theeffects of teacher feedback during the development of an online discussion forum. Over a three-week period, the participants (14 university students and their tutor) engaged in a virtual debate on the use of Wikipedia for academic purposes, using the Knowledge Forum platform (participants made 328 posts in total). Based on characteristics of online learning environments, we developed a multidimensional model to study feedback and its effects during online interaction. The results show the main effects of the teacher's feedback both on the students' discussion about learning topics -chain effect and cluster effect-and on the rules of participation in the debate. The paper concludes with a discussion on the theoretical and practical implications of these results.24 p.application/pdfengcc-by-nc-nd (c) Servicio de Publicaciones, Universidad de Murcia , 2021https://creativecommons.org/licenses/by-nc-nd/4.0/Retroacció (Psicologia)Educació superiorInteracció educativaFeedback (Psychology)Higher educationInteraction analysis in educationinfo:eu-repo/semantics/article7152472021-11-23info:eu-repo/semantics/openAccess
