powerpoint multimedia presentations in computer science education: what do users need?
DESCRIPTION
Presentation given at USAB 2008, Fourth International Symposium on Usability and HCI for Education and Work, Graz, Austria, November 2008 ABSTRACT: PowerPoint is one of the most frequently used tools to present multimedia for educational purposes. Nevertheless, little is known about the users' needs when using PowerPoint during lecturing. Our study focused on the presenter's needs in this context of use. We interviewed nine university lecturers from the computer science department by means of a questionnaire. The results show that users require features that are not yet realised with PowerPoint. For example, the control and use of other media should be adequately integrated. Or the navigation within the slide collection should be improved to better meet the users' needs. Based on our findings, we outline required system features and suggest solutions in form of a prototype.TRANSCRIPT

lectures with PowerPoint
Our goal: investigate these user needs and
develop an enhanced PowerPoint based
presentation tool
