Abstract: An activity control system for a networked computer-aided learning system comprises a tutor workstation (1), at least one student workstation (2,3), and a network (8) interconnecting the tutor workstation and the student workstations. A tutor application (11) in the tutor workstation provides a user interface by which a tutor is able to remote-control the browsing functionality of a web browser in the student workstation over the network. A web server (7) providing access to a variety of learning material which is in form of a plurality of web pages comprises a hyperlink to a configuration file for the user interface of the tutor application. The configuration information defines a predefined lesson plan including predefined web page links. When downloaded into a user's computer in response to activation of the hyperlink, the configuration information configures the user interface according to the predefined lesson plan to display the predefined web page links.
