Classroom Technology Work at University of Washington

1. Classroom Technology Work at University of Washington Richard Anderson (UW) Ruth Anderson (UVa) Steve Wolfman (UBC)

2. Educational Technology …in the winter of 1813 & '14 … I attended a mathematical school kept in Boston…On entering his room, we were struck at the appearance of an ample Black Board suspended on the wall, with lumps of chalk on a ledge below, and cloths hanging at either side. I had never heard of such a thing before. [Samuel J. May, 1855]

3. Goal: Improve interaction in the classroom • Provide flexible mechanism for delivery presentation • Support interaction between student and instructor devices around presentation materials

4. Classroom Presenter • Integration of slides and digital ink using Tablet PC • Key ideas: • Ink overlay on images • Distributed application • Many other systems also support ink and slides

5. Ink Usage In Exposition • Initial motivation • Increase flexibility of slide based presentation • Adjust presentation in response to the audience

6. When is ink important? • Ink is NOT always important for slide based presentation • Classroom presentation is different from professional / conference / meeting presentation • Ink is important when: • The instructor interacts with the audience • Displayed material is the focus of attention

7. Examples of Ink Usage • Slides from selected university courses • Demonstrate range of use in class

8. Attentional ink and incidental writing

9. Writing with mathematical content

10. Stepping through example

11. Diagram augmentation

12. Diagram AugmentationInstructor view

13. Rich Diagrams

14. Fill-in simulation

15. Process Trace

16. Collective Brainstorming

17. Collective BrainstormInstructor View

18. Ink based demonstrationQuikwrite [Perlin, NYU]

19. Instructor notes INSTRUCTOR NOTE • Different layers available in different views • Base, Instructor, Student, Shared • PPT Plug in allows creation of notes

20. 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

21. Tablet PC Ink Multiple Colors Highlighter Stroke Erase Page Erase Undo Slide Minimize Whiteboard Multiple Decks Filmstrip Navigation Slide previews Ink Export Presenter Features

22. Form factor issues • Carrying the tablet while lecturing • Some like to carry the tablet, others don’t • Weight and size are issues • Eye gaze is a problem • Vision angle and reflection can be problems for instructor • Tablet button fumbles • “And I see Windows is shutting down” • “Here is the Australian view”

23. Interaction with student devices • Student note taking • Classroom Presenter Student View, RemarkableText (Brown U.), One Note • Embedded Classroom Activities • SIP (Structured Interaction Presentations) • Student Submissions

25. Student Submissions with Classroom Presenter Ruth Anderson

26. Student Submissions • Students annotate slide • Submit ink to instructor • Instructor selectively displays student responses to the class Motivation: to promote student involvement with lecture

27. Trace the path of Lewis and Clark from Saint Louis to Astoria

28. Find the roots of x2 + 3x + 4

29. Show that increasing supply of housing lowers equilibrium price p pe 100 QD,QS

30. Student Submissions • Supports Active Learning where students with Tablet PCs can complete an activity • submit anonymously • student work reviewed/discussed/augmented selectively by instructor • electronic copy of student work available after class • use rich backgrounds and color

31. Preliminary experiences • Problem solving in parallel • Multiple solutions and misconceptions • Allow independent work • Spontaneous activities with structure • Build on instructor designs or scaffolding

33. Uncover Common Errors

34. Compare Different Approaches

35. Use Background Slide & Color

36. Solve Different Problems in Parallel

37. Problem Solving

38. Assessment of Student Learning

39. Spontaneous Activities

41. Steve Wolfman • Structured Interaction Presentations

42. lecture active learning student-directed instructor-dominated interactive disconnected participatory passive Overgeneralization borne out by research Modern Pedagogy vs. Modern Practice ~80-90% lectures Thielens, 1987

43. Goals of Structured Interaction Presentation System (SIP) Make design and execution of interactive presentations as easy as for passive ones. • Keep best of PPT & augment interaction • Integrate into the “mediating” slides • Support intuitive and flexible design • Facilitate interaction in class • Enable new kinds of interaction “transitions”, apprehension e.g., data reuse, intentional grouping, DHC; Also old kinds like “Is PPT Evil?”
