State of US Engineering Education
• Static student enrollments in ECE
• International competition– esp. Pacific rim
• US undergraduate enrollments impacted– Offshore job migration perceptions– Dot-Com Bust
• Lack of diversity– Found in ECE faculties– Low minority / women student enrollment
• “Programs are largely unchanged since the Sputnik era” [Bruce Kramer, NSF]
CEEN Goals
• Improve student retention– 1st year: 50% average– 2nd year: 20% average
• Attract more students– Underrepresented minorities– Women
• Enhance:– Level of individual creativity– Sense of discovery from courses and laboratories
• Increase faculty research and satisfaction
Department Objectives: Education
• Search for a unifying theme– Enhance student interest– Bring anticipation for the next course in the sequence
• Increase outreach to K-12 students– Schools with high underrepresented minority
populations• e.g., Omaha Public Schools
Research That Improves Faculty Productivity
• Proposal: sharing CEEN courses– Analogy: Like farmers of old sharing implements and
working together– With upper-Midwest ECE departments– Increase subject availability to students– Free more faculty to pursue other research and
educational opportunities
• Advantage: Internet2 Abilene Network– Distribute and receive courses
Education Solution Paths
• Applying the TekBot robot– Developed as a learning platform at Oregon State U.– Diffuse into the CEEN programs into all 4 UG years
• Review NSF programs– Support for program improvements and outreach to K-12
• Solution:– Outreach: NSF ITEST (Information Technology Experiences For
Students and Teachers)– Self-improvement: A&I (Adaptation and Innovation)
• Announcements pending in Aug./Sept. for $1.2M and $160K
The Access Grid (AG)• Access Grid offers:
– Multimedia large-format displays– Presentation and interactive environments– Interfaces to Grid middleware and to visualization environments– High-end audio and visual technology needed to provide a high-quality
compelling user experience
• AG supports distance group-to-group interactions across the Grid.– e.g., uses of AG:
• Large-scale distributed meetings / collaborative work sessions• Seminars / training• Lectures / tutorials• Virtual site visit meetings / remote panel discussions / grid based
demonstrations• Research
• The Access Grid has member sites in over 47 countries
Access Grid Concepts
• AG prototype Demonstration at UKY Chautauqua– Shared PowerPoint– Large-format displays– Multiple audio and video streams– Supporting distributed meetings

The Next-Generation AG Powerhouse
• Right now PKI-161 supports:– Seamless screen real estate (Default: not seamless)– 26 students (Default: 3-10)– Multiple presenters at same site (Default: 1 per site)– Multiple media formats at the same time: DVD/VCR, visual
presenter, Sympodium, SMARTBoard, Instructor PC/Laptop (Default: one or none at a time)
– Hands-on or hands-free microphone system (Default: hands-free)
– Uses of: distance education and video conference (AG, Polycom, or AG/Polycom),… also presentation room and normal classroom (Default: video conference only)
Our Access Grid Project Goals• Connecting people and teams via the Grid
• Improve the user experience– Drop the idea of one-on-one teleconferencing– Provide a sense of presence– Support natural interaction methods
• Implement quality and efficient digital IP-based audio/video– AG development of HD / DV or MPEG-4 video
• Enable complex multi-site visual and collaborative experiences– HeyeWall, VR Caves– Distance Learning
• Build on integrated Grid services architecture– Develop new tools specifically to support group collaboration
Our AG Active Research Issues
• Recording, playback, and production of multistream media
• Friendly AG: AG to the end-user desktop– Potential replacement for NetMeeting, etc.
• Secure communications via AG
• Improving sense of presence and point of view
• Network monitoring and real-time management
• Role of Back-channel communications
Why Travel?
• A few current professional reasons for travel:– Taking courses from a distant university / school– Face-to-face business sessions or training workshops
• Problems:– Post 9/11 concerns
• How safe are the skies?
– Costly for everyone involved• Monetary: travel, hotel, car rental/taxi fees, lost
work/productivity• Human condition: no home comforts, separation of family
Why Travel… When You Can Use AG?
• AG is the solution– Real-time face-to-face meetings– Multiple media formats– Cost effective (find a node in your area)
• PKI-161– Shown in the previous slides
Satellite COmmunications for LeAarning (SCOLA)
• SCOLA provides:– Real-time video of foreign language programming
• News and cultural programs in native languages from 58 countries in 44 languages
– 3 channels of programming delivered to:• Colleges, K-12 schools, cable systems, foreign language and
foreign policy institutes
