Audience Expectations

• Get justification for Class Capture concept

• Demonstrate feasibility of capture and video streaming without the requirements of an operator

• Develop guidelines for analyzing marketplace system choices for your campus

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

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)

PROJECTION CAPABLE CLASSROOM STANDARD

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.

• Develop easy to use system• Demonstrate project feasibility• Develop classroom automation• Develop server process automation• Utilize faculty input• Evaluate outcomes• Make recommendations

Survey Results

Survey Results- 63 students

• Most students attended class regularly• Streams were viewed mainly in afternoons• Low demand for dial up connections• Stated benefits included exam study and

to review or clarify material• Desire for more flexibility in content

delivery (e.g. downloads for iPods)• Little interest in audio-only downloads Cont’d

Survey Results- comments

• “Beneficial to pause and replay lectures”• Video of professor “was not valuable”• Want “more playback speed control”• “Downloads would allow review offline”• Review makes up for “zoning out in class”• Most judged scan converted video as

“good or excellent quality”• Some indicated desire for “higher

resolution”

Conclusions

Conclusions

• Low end video streaming can adequately support asynchronous classroom recall

• Instructor indicates satisfaction with system

• Pilot system interfaces with campus technology classroom design standard PCC (Projection Capable Classroom)

• Classes were captured reliably without an operator

Cont’d

Conclusions

• It is impractical to scale multiple departmental servers to support video streaming in General Purpose classrooms

• Students would prefer the option of down loading lectures to portable devices

• Students indicate the computer image is more important than the instructor video

Recommendations

Recommendations

A future streaming system should:

• allow a multi-windowed display with sizing controls

• provide high resolution computer image quality

• Allow down loading of files to portable devices

Cont’d

Recommendations

• On a large scale, either a central server farm or an exclusive IT collaborator needs to be employed

• Analyze up front and life cycle costs for scalable implementation on campus

• Chosen system should integrate with campus CMS (WebCT Vista)

Cont’d

Recommendations

• A full investigation of marketplace class capture systems needs to be implemented and analyzed for UofM needs

• A server farm collaborator should be sought out

• Faculty should be surveyed to determine degree of system control desired

Cont’d

Recommendations

• System chosen must integrate with the standard Projection Capable Classroom

• System should be chosen to allow instructors to teach as they normally would

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 – HIPAA privacy issues

Video Streaming Pilot Project Conclusion• The Pilot successfully demonstrates the feasibility

of the no-operator 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 hardware and software choices.

• Final project survey evaluations will be posted at:
