  • OCM University of Minnesota Office of Classroom Management OCM is the central point of contact, and single point of responsibility, for all general purpose classroom issues on the three Twin Cities campuses. Classroom Technical Services (CTS) operates as the technical support organization for OCM.
  • The UofM Challenge: • Advanced data-projection capability • 300+ classrooms • Easy-to-use systems • Reduced maintenance costs • Improved classroom uptime • Ability to interface new devices
  • PROJECTION CAPABLE CLASSROOM STANDARD  Includes basic tech infrastructure for teaching & learning • fixed data/video projection capability • internet connectivity at instructor station • wireless student networking • smart control system with networking option • user friendly laptop interface • standardized operating protocol familiar to UofM faculty • standard input devices (VCR and DVD) • may have other modular “add-on” capabilities • “Hotline” phone for instructor • accessibility features • flexible growth potential - able to interface new devices  Baseline for UMTC general-purpose classroom technology • Included in Facilities Construction Standards (Appendix DD)
  • OCM Technology Upgrade Plan To bring laptop projection capability (Phase I) and student wireless networking (Phase II) to all centrally scheduled Twin Cities classrooms (approx. 307) at the University of Minnesota under a Classroom One- Stop umbrella.
  • Phase III Concept
  • Phase III • Low-End Asynchronous Video Streaming capability is also under consideration as “Phase III” of the ongoing Tech Upgrade program for UMTC central classrooms.
  • “Low-end” • “Low-end” means a low cost, relatively simple capability to capture and archive teaching activity that occurred in a classroom.
  • “Low-end” asynchronous video streaming- Priorities • Operator replaced by affordable technology • Easy to use • Transparent from the instructor’s perspective
  • “Low-end” asynchronous video streaming • Would support on-demand recall of classroom activity • Would not support live streaming • Relatively simple capture and archive • Would be scalable from installation, support and lifecycle cost perspectives
  • Pilot Project
  • Project Objective • To evaluate the concept of adding modular technology to the standard Projection Capable Classroom system that would provide faculty with the capability of capturing and asynchronously streaming classroom activity without the requirements of an additional operator.
  • Project Processes • Develop easy to use system • Demonstrate project feasibility • Develop classroom automation • Develop server process automation • Utilize faculty input • Evaluate outcomes • Make recommendations

  • Issues
  • Issues • Classroom Capture • File Transfer Process • Automation Process • Student Streaming Delivery • Faculty Perception • Student Perception • Use Statistics • Future Applicability/Projections
  • Issues • Initial protocols required the class to be MPEG-4 streamed from the classroom and asynchronously streamed upon demand from the server • QTSS (Quick Time Streaming Server) can’t both archive a captured stream and multicast from an archive • Archive at the Encoder, Stream at the Transcoder • Solution had to target a file transfer protocol, not a captured stream cont’d
  • Issues • Hardware specific encoder issues determined the server automation configuration, and …………….. • triggered many specific solutions for dealing with streaming failures, archiving difficulties, remote access problems, processing procedures and firmware upgrades. Cont’d
  • Issues • Scan converted video vs. Hi-Res option • Future cost benefit analysis will be dependent on resolution requirements driven by students, faculty and/or administration • Technology improvements will continue to drive hardware price down
  • Issues • The Future Campus Streaming Server Farm – Standard – Owner – Cost – Interface Requirements – Automation process – Authentication method – CMS interface (Vista)
  • Preliminary Observations
  • Video Streaming Pilot Preliminary Observations • Final Evaluation targeted for end of Spring Semester • Faculty Project Partner indicates positive instructor experience • Initial informal student feedback is positive, awaiting formal survey • Pilot demonstrates feasibility of automated technology system Cont’d
  • Video Streaming Pilot Preliminary Observations • The server solution is more complex than the classroom solution • Although operational server solution was developed, future server farm will be by others • The future server farm solution will drive future encoder and process requirements Cont’d
  • Video Streaming Pilot Preliminary Observations • A low-end fixed instructor camera is workable but future instructors may demand auto-tracking camera system • Low-end scan converted video is adequate but future requirements and stakeholders may demand higher resolution • Once faculty are operator assisted, they have no motivation to retrain. Cont’d
  • Video Streaming Pilot Preliminary Observations • Classroom capture automation system successfully functioned • Regardless of future server requirement, classroom capture system should interface • Manual streaming start control was requested, but automated start may be a future feature/requirement Cont’d
  • Video Streaming Pilot Preliminary Observations • The pilot indicates we can capture one class three times a week for asynchronous recall by 250 students…….. • It also indicates that to capture many classes for recall by large numbers of students would require a different server configuration and methodology. • This and many other reasons indicate the need for a central server farm by others.
  • Related Capture Issues Hovering in the Wings • Competing issues of negative effect on attendance vs. review aid • Classroom Visual Aid versus Distant Ed Delivery • ROI with regard to increased tuition revenues • Fair Use – Determination on classroom DVD/media content streamed over Network – Fair Use requirement on archived file time limit
  • Video Streaming Pilot Preliminary Evaluations • The Pilot successfully demonstrates the feasibility of the low-end video streaming concept. Final configuration of future implementation will depend on input from many stakeholders, but the lessons learned in this project will aid in answering questions regarding functional, operational, technical, financial and usability issues. • Final project survey evaluations will be posted at: • http//:www.classroom.umn.edu
