state of us engineering education
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
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
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
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
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
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
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
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
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
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
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
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)
