  1. Education Technology 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 > 40 Computer Science courses at UW, UVA, USD, and elsewhere. • Available free for educational and research use: www.cs.washington.edu/education/dl/presenter/

  5. Related Work • Lecturer’s Assistant [Buckalew] • eClass [Abowd, Brotherton] • TMS [Golub] • DEBBIE/DyKnow [Berque] • PowerPoint with Tablet extensions • Tablet PC Journal

  6. Presenter Configurations • Single Machine (1 Tablet PC) • Direct projection from instructor view • Single view, tethered • Projection of second monitor from tablet • Multiple views, but tethered • Multiple Machine (1 Tablet PC + Other devices) • Wireless connection to display view • Multiple views, untethered • Distance learning and integration with student devices

  7. Instructor View

  8. Projector View

  9. Presenter Deployments > 40 different classes at UW, UVA, USD, and elsewhere > 20 different Instructors > 2000 students (Class sizes: 7 - 211 students) Courses: Intro Programming,Software Engineering, Algorithms, Architecture, Digital Design, Compilers, Data Structures, Programming Languages, Graphics, Networks, Discrete Math, Ethics, Databases, AI, HCI

  10. Presenter in Distance Course

  11. Archived Lecture of Instructor Using Presenter

  12. Student Survey Results

  13. Examples of Use • Instructor Notes • Interactive Writing • Diagrams • Attention Mechanisms

  14. Instructor Notes • Private notes viewable only by instructor • Reminder of important points to emphasize • Contents of blank spaces to fill in • Answers to math calculations

  15. Interactive Writing

  16. Whiteboard Feature

  17. Sparse Slides

  18. Walking Thru Examples

  19. Dynamic Corrections

  20. Diagramming • Annotate interactively with ink • To draw attention to details • To trace a process

  21. Marginal Diagrams

  22. Rich Diagrams

  23. LW inst DISP empty lw without the displacement Red:PC Blue: Dest Green: Source 9 control lines: You must show values for all What if I want to Support both styles of lw/sw? Jump Branch MemRead MemWrite 0 0 1 0 ALUSrc ALUOp MemToReg RegWrite RegDest X X 1 1 0

  24. Attention Mechanisms • Draw attention to specific content on the slides in a persistent manner. • Checks • Underlines • Circles • Arrows • Grouping related points • Focus attention

  25. Summary • System Implemented • Substantial deployment in CS courses • Examples of Usage Classroom Presenter addresses problems with computer-projected slides

  26. Classroom Presenter Available free for educational and research use: www.cs.washington.edu/education/dl/presenter Ruth Anderson ruth@cs.virginia.edu
