Social Navigation in Web Lectures

Robert Mertens, Rosta Farzan, Peter Brusilovsky


Web lectures are a form of educational content that differs from classic hypertext in a number of ways. Web lectures are easier to produce and therefore large amounts of material become accumulated in a short time. The recordings are significantly less structured than traditional web based learning content and they are time based media. Both the lack of structure and their time based nature pose difficulties for navigation in web lectures. The approach presented in this paper applies the basic concept of social navigation to facilitate navigation in web lectures. Social navigation support has been successfully employed for hypertext and picture augmented hypertext in the education domain. This paper describes how social navigation can be implemented for web lectures and how it can be used to augment existent navigation features.
