  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

  6. 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

  7. 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

  8. 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 Pedagogical Goals

  12. 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

  13. 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

  14. 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

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

  16. 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

  19. Lecture Playback: Webviewer • Integrated synchronized playback including: • Audio/Video • Instructor slides and ink • Student submissions

  21. 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

  22. 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
