6 Pittsburgh Greensburg Johnstown Bradford Titusville University of Pittsburgh  Founded in 1787  Five campuses  Eighteen Academic Centers  Graduate, undergraduate, professional, and continuing education programs  30,102 Fall-term FTE  4,411 full- and part-time faculty members

7 Janus – Capturing Whiteboards

8 The Janus Model Hitachi (Wacom) LCD Panel Altinex VGA Splitter Hitachi StarBoard Software

9 Janus Deployment at Pitt

10 Super-Janus: Plasma SmartBoard

11 Instructional Application: Virtual Whiteboard

12 Instructional Application: Screen Annotations

13 InterWrite School Pad  Mobile graphics pad  Can act as a mobile mouse  Enables annotations on the computer screen  Enables virtual whiteboard applications  Uses wireless Bluetooth technology

14 Tegrity Audio and Video of Instructor Instructor’s Desktop Pointer Index Navigation Tool Area for Closed Captioning A/V Controls

15 The Tegrity Model

16 Tegrity Distribution

17 MediaSite Live

18 The MediaSite Live Model

19 MediaSite Live Distribution

20 Supplementing Tegrity/MSL Include VHS/DVD Video Integrate with ITV

21 Issues and Considerations  Goal is to capture “live” presentations, but presenters want to do post- production edits  Tegrity provides limited editing  The typical class is too long (2-3 hours)  Limit to from 10 to at most 20 minutes  Provide instructional designer assistance  Video/Visual content and accessibility  Tegrity enables closed captioning

22 Issues and Considerations  High quality recordings require high bandwidth  Consider distributing content via CD and accessing via “off-line content” in Bb  Some “cognitive overhead” comes with the technology  Provide an operator to assist instructor  Budget and/or charge back for costs of replacement technology and operator

27 University of Florida  Conversion of introductory Statistics and Writing to streaming-lecture format  Other streaming courses at UF include:  Business undergraduate and graduate courses  Engineering courses  Many individual courses and individual components

28 University of Florida  The Classroom  34-seat table/chair classroom  Data projector, camera, wireless microphone, document camera, computer

29 University of Florida  The Courses  STA 2023: Introduction to Statistics  2300 students in Fall 2003  ENC 1101: Introduction to College Writing  1339 students in Fall 2003  ENC 1102: Argument and Persuasion  657 students in Fall 2003

30 University of Florida  The Logistics  Output format from classroom is NTSC video  Transmit across campus by fiber or tape for encoding/streaming at remote site  Transport tape to TV station for playback  Post-production or not is choice of instructor

31 University of Florida  The Delivery  Residence Hall Cable  Local Cable TV  On-Demand Streaming

32 University of Florida  The Costs  Classroom ($12,500 total)  Projector ($4000)  Camera on fluid-head tripod ($800 to $3500)  Computer with video-out ($1000)  Document Camera with video-out ($2000)  PIP Video Switcher ($1000)  Monitors for Instructor and Camera Operator ($500)  Wireless microphone ($500)

33 University of Florida  The Costs (Transport Mechanisms)  Analog fiber: $2700 plus fiber cost  MPEG-2 codecs: $18,000 or less per pair  Staff to transport DVCAM tapes

34 University of Florida  The Costs (Logistics and Servers)  Logistics  Personnel, including camera operator, encoding technician - $2500  Streaming Servers  Racks, switches, RAID arrays, NAS and streaming servers - $27,000

35 University of Florida  The Benefits & Savings  Reduced large lecture hall usage  Students have on-demand access to lectures  90% of statistics students choose to watch online  Makes it possible to spend effort on lab sections and discussions

36 University of Notre Dame Kevin Abbott

37 UNIVERSITY OF NOTRE DAME  Founded in 1787  Located in Notre Dame, Indiana  Five Colleges  Graduate, undergraduate, professional, and continuing education programs  8,000 Undergraduate students  3,000 Graduate students  1,600 full- and part-time faculty members

38 The Notre Dame Approach  The Notre Dame Approach allows those with small budgets or a need to quickly capture a class the ability to do so easily with little or no infrastructure and experience required.  Asynchronous learning, both Local and Distant  Low-cost  Manually intensive  Flexible  Easy to learn  Primarily for class archival in large classes  No live capture and distribution  Little infrastructure needed

39 Who Is Using This at Notre Dame?  Executive MBA Program  Students only on campus once a month  Needed courses delivered when not on campus  Physics  International study abroad program  Required course  7 students spread throughout Europe, 6 on campus  Needed same day access to class  Economics  Archival for large intro classes for review and those who missed class

40 What Steps Are Required for This?  Record  PowerPoint Narration used for recording  Wireless Lavalier Microphone used for audio input  Mobile Drive used for saving recording  Process  Save PowerPoint slides as JPEG files  Edit audio files if needed with Sound Forge  Insert slides and audio files into Software  Output  Serve files through http or streaming server

41 What Tools are Needed?  Record  PowerPoint > Record Narration  UHF Wireless Lavalier Microphone  40GB Mobile Drive  Process  For Flash – Flash MX 2004 Slide Feature  For Windows Media – Windows Movie Maker  For QuickTime – LiveSlideShow 2.0
