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

25
Founded in 1853 Located in Gainesville Seventeen Colleges Graduate, undergraduate, professional, and continuing education programs 34,000 Undergraduate students 13,000 Graduate students 3,700 full- and part-time faculty members
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

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
