1. ConferenceXP for Tutored Video Instruction Richard Anderson, Fred Videon University of Washington ConferenceXP Workshop November 2, 2006

2. Outline Course offering between University of Washington (Seattle) and Beihang University (Beijing) Tutored Video Instruction Classroom Interaction Supporting technology

3. Goal: Offer UW Course at Beihang University Motivation Allow course offerings that are not currently available UW-MSR-Beihang Partnership Computer Science Course Undergraduate Algorithms Initial proposal UW Professor spend a semester in China Not possible for many reasons

4. Timing issues for offering a UW course in China Course to be offered Fall 2006 at UW UW – term: Sept 27 – Dec 15 Beihang - semester: Sept 1 – Dec 30 Live video conferencing not feasible UW Course 1:30-2:20 pm, MWF Beijing – 4:30-5:20 am.

5. Tutored Video Instruction Base course on facilitated use of recorded materials Materials recorded from a live class Facilitator guides discussion around materials Gibbons, Science 1977

7. TVI Offering of UW Course in Beihang Capture of UW course offered Fall 2006 Beihang course uses UW lectures and other materials Same text and assignments UW Instructor visits in September and November Local facilitators support the course

8. Classroom Presenter Tablet PC Based Classroom Interaction System Students contribute to class using digital ink on instructors slide Instructor views student submissions, and selectively shows them to the class Activities embedded into slide based lecture Contrasts to ‘Classroom Networks’ pedagogy Individual vs. Aggregated responses

9. Pedagogical Goals Encourage students to contribute in multiple ways Promote engagement in the class Interest Alertness Demonstrate that all students have important opinions Peer interaction Feedback – classroom assessment Collection of ideas Collective brainstorm Student generation of examples Discovery of a pedagogical point Gain understanding of an example Show misconceptions

13. What we are trying to achieve Reproduce interactive classroom experience in a remote classroom Moderate level of spoken interaction in UW course Promoting interaction in remote classroom Design of UW lecture materials to encourage interaction Supporting materials – directions on when to stop for questions Classroom Technology

14. Technology Overview Lecture recording: The UW classroom ConferenceXP at the core of our archiving strategy Lecture preparation Packaging is automated with CXP Archive Transcoder Playback: The Beihang classroom Integrated AV/Presentation Playback using CXP WebViewer

15. Building on Past Work with CXP CXP deployed for distance learning since 2002 Dedicated distance learning classroom UW Classroom Presenter UW CXP extensions focusing on archive preparation and playback

16. Recording: The UW Classroom All devices use CXP Multicast Networking CXP Archive Service provides a simple way to collect all classroom activity Multicast CXP Archive Service CXP Audio/Video Classroom Presenter Instructor Classroom Presenter Student Devices …

17. Lecture Packaging: CXP Archive Transcoder Extract audio/video streams from Archive Service Database as WMV Transcode WMV to preferred profile Basic AV editing: crop, join, audio mixing Classroom Presenter data transformations targeting CXP WebViewer End result is a self contained downloadable package

22. What we’ve learned so far The course is in progress – feedback is positive, but we won’t really know what is going on until one of us visits Students will take UW Midterm and Final, so there is going to be information on student performance

23. Technology Generally working well Some minor glitches with new version of Classroom Presenter Audience audio is a problem for replay Student noise is distracting A “facilitation interface” for Presenter/Webviewer would be great! Lecture review by UW instructor is time consuming
