Title: Experiences with a Tablet PC Based Lecture Presentation System in Computer Science Courses


1
Experiences with a Tablet PC Based Lecture
Presentation System in Computer Science Courses
2
Outline
  • Problem Addressed
  • Related Work
  • System Description
  • Deployments in CS Courses
  • Examples of Use

3
Slides Projected from Computer
  • Pros
  • High quality materials
  • Ease of sharing and re-use
  • Ability to switch to other computer applications
  • Cons
  • Limits Flexibility of Presentation
  • e.g. respond to student questions, work out
    examples in real time, integrate student input
    into presentation

4
Classroom Presenter
  • Tablet-PC
  • Slide-Based
  • Distributed Application
  • First deployed in Summer 2002
  • Deployed in gt 40 Computer Science courses at UW,
    UVA, USD, and elsewhere.
  • Available free for educational and research use
