One University of Copenhagen researcher studied exactly that in a study just published in the Danish journal, Læring og Medier (Learning and Media). Something that surprised us was how active online students were in terms of asking questions about their instruction. They asked plenty of questions in their chats, unlike physical attendees, who asked very few questions to lecturers," explains Helle Mathiasen, the Department of Science Education professor behind the study. Together with e-learning consultant Henrik Bregnhøj of UCPH's Centre for Online and Blended Learning (COBL), she included 282 lectures delivered at the University of Copenhagen's pharmaceutical, medical and veterinary faculties and analyzed instant message records of three lectures. Furthermore, Helle Mathiasen conducted 15 group interviews with students regarding their instructional experiences.
