PowerPoint Multimedia Presentations in Computer Science Education: What Do Users Need?

Presentation given at USAB 2008, 4th Symposium on Usability & HCI for Education and Work, Graz, Austria.

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.

    Motivation
    ▪ PowerPoint is one of the most commonly used
    presentation tools
    ▪ Little is known about user needs for delivering
    lectures with PowerPoint
    ▪ Our goal: investigate these user needs and
    develop an enhanced PowerPoint based
    presentation tool

    Study Design
    ▪ 9 computer science faculty members, age 25-62
    ▪ ETH Zurich and University of Zurich
    ▪ Method
    ▪ structured interviews (on average 37 minutes)
    ▪ collected a sample presentation from each participant
    ▪ Questions
    ▪ status quo of PowerPoint in lectures
    ▪ does PowerPoint satisfy the user needs or what
    additional functionality is desired
