    1. 1. Using Streaming Media for Online User Training in IT John Fritz Bill Shewbridge University of Maryland, Baltimore County EDUCAUSE, October 2, 2002
    2. 2. Overview <ul><li>UMBC Background </li></ul><ul><li>Basics of the Production Process </li></ul><ul><li>UMBC Examples </li></ul><ul><li>Lessons Learned </li></ul><ul><li>Presentation And Contact Information </li></ul>
    3. 3. Institutional Drivers for Using Technology at UMBC <ul><li>Faculty </li></ul><ul><ul><li>By and large, about 75% of our faculty are comfortable with basic technology (email/web) and exploring various stages of how technology can be used to improve learning. </li></ul></ul><ul><li>Assured Access to Computing Initiative </li></ul><ul><ul><li>Focusing on providing all students with access to technology. </li></ul></ul><ul><ul><li>Student expectations: they are beginning to expect and request courses to utilize technology. </li></ul></ul><ul><li>Institutional Support </li></ul><ul><ul><li>FaCT program was successful in getting faculty started. </li></ul></ul><ul><ul><li>OIT and the Faculty Development Center provide joint faculty training sessions and brownbag workshops </li></ul></ul>
    4. 4. Classifying Technology Usage <ul><li>Technology Enhanced Learning (TEL) </li></ul><ul><ul><li>Technology augments in-class learning with the focus on providing course information and additional online resources.This represents the bulk of our current faculty usage </li></ul></ul><ul><li>Online Courses </li></ul><ul><ul><li>Technology provides the means of running the course and a full complement of course information. </li></ul></ul><ul><li>Hybrid Courses </li></ul><ul><ul><li>Course meets in-class and online. In-class sessions are reduced and the class meets online for discussions, group work and assessment. </li></ul></ul>
    5. 5. Fall 2001 Instructional Technology Activities <ul><li>Computer classrooms – 84 courses </li></ul><ul><ul><li>OIT labs support 84 classes using technology enabled classrooms </li></ul></ul><ul><ul><li>Reached saturation 3 years ago and have worked with Physics, GES, and English to create departmental facilities </li></ul></ul><ul><li>Blackboard – 234 courses with 6,436 distinct students </li></ul><ul><ul><li>Usage is predominately in the social sciences and humanities </li></ul></ul><ul><ul><li>Doubled student enrollments each of the past 3 years </li></ul></ul><ul><ul><li>Expanding into organizational support areas (Delta Initiative, Faculty Senate, Student Affairs) </li></ul></ul><ul><li>Faculty-developed course web pages </li></ul><ul><ul><li>Usage is predominately in the sciences </li></ul></ul>
    6. 6. Why Online IT Training? <ul><li>Support crunch necessitated a more scalable approach </li></ul><ul><li>Video on demand is more flexible by the end user </li></ul><ul><li>Availability of a robust, broadband infrastructure (e.g., IPTV, Internet2) </li></ul><ul><li>We could train users on UMBC specific IT issues they couldn’t find elsewhere: </li></ul><ul><ul><li>Publishing web pages @ UMBC </li></ul></ul><ul><ul><li>Using the campus portal myUMBC </li></ul></ul><ul><ul><li>Creating and managing your user account </li></ul></ul>
    7. 7. Initial Approach <ul><li>Broadband Video for Training </li></ul><ul><ul><li>MPEG1 and IPTV </li></ul></ul><ul><ul><li>Example: </li></ul></ul><ul><ul><ul><li>PowerPoint in the Classroom </li></ul></ul></ul><ul><ul><ul><li>ResNet Installation </li></ul></ul></ul>
    8. 8. Lessons Learned and Refocus <ul><li>Limits of MPEG for screen capture </li></ul><ul><ul><li>FINWeb MPEG </li></ul></ul><ul><ul><li>FINWeb Screen Captures </li></ul></ul><ul><li>Recognition that multiple solutions are needed </li></ul><ul><li>Criteria for media selection </li></ul><ul><ul><li>Quality of delivery </li></ul></ul><ul><ul><li>User Accessibility </li></ul></ul><ul><ul><li>Production Issues </li></ul></ul>
    9. 9. Streaming at UMBC <ul><li>IPTV Mapping the Patapsco (MPEG) </li></ul><ul><li>Screen Capture ( FINWeb ) </li></ul><ul><li>QuickTime w/ PowerPoint </li></ul>
    10. 10. Production Process Basics <ul><li>Pre-production </li></ul><ul><ul><li>Content development </li></ul></ul><ul><ul><li>Organization and efficiency of material and resources </li></ul></ul><ul><ul><li>Allocating resources </li></ul></ul><ul><ul><li>Multimedia integration issues </li></ul></ul><ul><li>Production </li></ul><ul><ul><li>Acquisition </li></ul></ul><ul><ul><ul><li>Cameras </li></ul></ul></ul><ul><ul><ul><li>Formats </li></ul></ul></ul><ul><ul><ul><li>Audio </li></ul></ul></ul><ul><ul><li>Graphics </li></ul></ul><ul><ul><li>Post-production </li></ul></ul><ul><ul><li>Editing </li></ul></ul><ul><ul><li>Multimedia Integration </li></ul></ul><ul><ul><li>Distribution </li></ul></ul><ul><ul><li>Evaluation </li></ul></ul><ul><ul><ul><li>Usability </li></ul></ul></ul>
    11. 11. Lower quality image, bad for lots of movement Accessible by most Marginal Narrowband (Real) Can accommodate high-end production values High bandwidth and client VHS-Quality Broadband (IPTV) Class prep Does Not Scale Great Live Face-to-Face Training Production Issues User Accessibility Quality of Delivery Method
    12. 12. Minimal resources and expertise Accessible by most High quality possible Audio Only Can require extensive postproduction Requires ubiquitous Plugin Great resolution - can be combined with Streaming Video Slide Shows Real-time Acquisition Requires Plugin with appropriate CODEC Excellent for Screens - Bad for Motion Screen Capture Production Issues User Accessibility Quality of Delivery Method
    13. 13. Extensive resources and skills needed CD must be distributed to user Can integrate variety of media. Bandwidth less of an issue. CD-ROM Full range of video production possible Requires a tape deck Great for full motion, weak on high resolution Video Tape Design issues, variable production expertise Easy access Broad range of options, generally static Web Sites Production Issues User Accessibility Quality of Delivery Method
    14. 14. Summary <ul><li>Online presentations are not a universal substitution for face-to-face training. They can however be an effective supplement. </li></ul><ul><li>Learning computer applications means looking at computer screens, but doing so through online video is difficult. </li></ul><ul><li>Producing “compelling” content requires more time and planning than one might think. </li></ul><ul><li>It takes time to change user expectations and support culture. If we can’t meet everyone’s needs, how can they adapt so they can meet their own? </li></ul>
