SLAYING THE GIANT: 300 Classrooms with Networked Control Systems Metacontrol at the University of Minnesota l Midwest Regional Educause ‘04 l Chicago, IL l James Gregory l University of Minnesota l
3 Introduction Networked Classroom Control Systems: A New Paradigm for Design, Operation and Support. l Metacontrol: The control of control systems.
4 The Challenge: To bring advanced data-projection capability to 300 classrooms and installing easy-to-use systems while reducing maintenance costs and improving classroom uptime.
6 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
7 OCM University of Minnesota Office of Classroom Management l Scheduling- Course Data Base l Classroom Support l Classroom Facilities Coordination l Classroom Technical Services
8 OCM University of Minnesota Office of Classroom Management Classroom Technical Services (CTS) l The strategic value of internal technology services –Faculty/Staff Communication/Responsiveness –Continuity of design philosophy –Standardization of systems –Synergy of technical expertise –Critical mass of engineers and technicians
9 OCM Technology Upgrade Plan: l To bring laptop projection capability, internet access and student wireless networking to all centrally scheduled Twin Cities classrooms (approx. 300) at the University of Minnesota.
10 Projection Capable Classroom Standard l Includes basic tech infrastructure for teaching & learning –Fixed data/video projection capability -- internet connectivity at instructor station -- VCR and/or other input device -- user friendly laptop interface -- standard operating protocol -- networked control system -- “Hotline” phone for instructor -- wireless networking -- May have other modular “add-on” capabilities Is the “baseline” for general-purpose classroom technology
Total Cost of Ownership Includes all the obvious and not-so-obvious costs of operating and maintaining the technology systems.
12 Recurring Lifecycle and Maintenance Cost Considerations
13 Recurring Cost Considerations Maintenance Costs: l Video/Data & OH projector bulb replacement l Video/Data projector filter maintenance l Data line/s & Phone line repairs l Repair of control, sound, media sources and all above systems l On call assistance and troubleshooting of systems
14 Design Factors (Install Cost & Ops/Staffing Implications) l Install Costs –Networking/ Wireless –Classroom Phones –Fixed vs. Carts –Fixed Classroom Computers l Operational/Staffing Costs –Computer Hardware Support –Software support –Phone Charges –Faculty Technology Support –Cart Support
15 Classroom Lifecycle and Maintenance Costs Technology Support Facilities
The Metacontrol Option A paradigm shift for lowering our maintenance and operating costs
17 Barriers Are Disappearing Audio/Video Information Technology
18 Overlapping Classroom Requirements Audio/Video Information Technology
19 Point of Integration Audio/Video Information Technology Intersection of network control with Multimedia-based communication
20 Types of Integration Points l Maintenance –Software Updates –Network downloadable l Monitoring –System Status –Error codes l Remote Control –Operation Takeover l Security –Online Tampering/Theft Notification
21 Both Sides Benefit & Bring Value Audio/Video Information Technology Internet, Access/Content Control, Communication, Security

30 Remote Control Features l Remote Control of: –Projector (on/off) –Sources (laptop, VCR, DVD, Doc Cam) –Video/ Audio Mute –Volume Level –System Lock-out –Service Mode
31 System Operation Normal
32 Data-Projector Monitoring l System reports hour meter readout on projector by inquiry l ( Projector error/status codes
33 Theft Prevention l Real time monitoring by the Campus Police through CTS management system l Local alarm and siren is activated by removal of projector or control lines l Password protection on classroom data projector
34 Equipment Management Module l Server and Management Software –Information Accumulation –History –Reports –Programmable Response configuration –Forwarding of Priority Notifications
35 Equipment Management Module l Software and server can accumulate time/date history of keypad selections on the system. l From this information, we can determine: –Equipment utilization statistics
36 U of M CTS Classroom Remote Monitoring System l Monitor classroom status l Receive alerts on problems l Hotline phone assistance l Manual takeover of controls l Compile data l Remote lockout l Schedule service l Remote shutdown for service l Theft alarms

41 Return On Investment (ROI) l Leveraged Returns (Value Added)
42 Technology Investment l Standardization l Ubiquitous Technology l Ease of Use l Metacontrol of Classrooms
43 ROI (Greater Classroom Quality) Measures: l Classroom Tuition $ –Efficiency –Economy –Return on tuition l Risk Management –Security –Technology Risk l Training –Controls Reduce Requirement l Equipment Tracking –Minimize Equipt. Checkouts
44 ROI (Greater Classroom Quality) Measures: l Increased Scheduling Efficiency l Higher Classroom Utilization l Reduction in Staffing Requirements l Reduction in Classroom Downtime l Reports & Trend Analysis l Faculty Attraction/Retention l Adoption of Technology l Leveraged Partnerships
46 Technology System Conclusions l Classroom One-Stop responsibility is important l Standardization and Ease of Use of Faculty interface is required l Future Technology demands will continue to grow l Lifecycle and Maintenance budgets must be obtained and justified l Metacontrol of classrooms is essential –http://www.classroom.umn.edu
