  • 1. Direct to Discovery: Learning Beyond the Bandwidth Barrier. Warren Matthews, Jessica Pater, Jeff Evans, and Claudia Huff. Georgia Tech Research Institute.
  • 2. About the Authors.
    • Georgia Institute of Technology in Atlanta, South East United States
      • Georgia Tech Research Institute.
    • Foundations for the Future (F3).
      • Integrating technology into K-12 Education for more than 10 years
    • Network Services (NS) group in the Office of Information Technology (OIT).
      • Provides campus network. Support researchers in the use of the network.
  • 3. How Did We Get Here?
    • Experience at using technology as a tool to solve a problem.
    • We saw a problem, we wanted to fix it.
    • Now report on the experience.
  • 4. Quote.
    • The central problem in science education is the poor performance of pre-college students. We know how to improve this: create innovative, research-based curricula and provide teacher professional development based on these materials. We do not need fundamental research in learning, a massive teacher recruitment program, or motivational awards. What is needed is to enrich what is going on in classrooms with better materials, more technology, and better-prepared teachers. - Bob Tinker, the Concord Consortium, August 2006.
  • 5. Abstract.
    • Direct-to-Discovery brings scientists and their labs into K-12 classrooms.
      • Students have direct access to scientists and research.
      • Students discover the wonder of science for themselves.
    • How is less important.
    • Why is STEM crisis, also because we can.
  • 6. Official Abstract.
    • This paper describes an innovative approach to using advanced networking technologies in support of technology-enabled K-12 learning within North America. This collaborative project involves multiple institutions in providing rich instructional resources in science, technology, engineering, and mathematics (STEM). Unique aspects include (a) providing access to advance cyber-infrastructure, i.e. Internet2 and National Lambda Rail, thereby allowing fully interactive bandwidth intensive applications; (b) delivering professional development for teachers and enriched learning experiences for students; (c) and is a replicable model that allows higher education to address pipeline needs within the STEM disciplines. Presented is a proven prototype as well as plans for future development, dissemination, and deployment. Potential collaborators are encouraged to contact the authors.
  • 7. Background.
    • The Georgia Institute of Technology
      • Highly ranked Engineering Research University
      • No College of Education
    • Tech operates the Southern Crossroads (SOX) exchange point
      • Provides access to Internet2, NLR and other national and regional networks
    • Partnered with Barrow County Schools in 2005 to address network and related issues. Direct to Discovery was born.
    • Focus areas:
      • High-speed network connection via PeachNet
      • HD video conferencing.
      • Numerous researcher providing content.
      • Also Professional Development and Evaluation component.
  • 8. Overview.
    • Events involve scientists.
      • Not K-12 outreach professionals.
    • Seek to bring research-based curricula to K-12 students
      • Excitement about science.
      • Career opportunities.
      • Philosophy of Science.
    • Not replacing teachers.
  • 9. Examples (1/3).
    • The following example is a class between a 7 th grade class (12-13 y.o.) at Westside Middle School in Winder, and the Microelectronics Research Center (MiRC), about 50 miles away.
    • Note clear video (although clip is only a Standard Definition recording of a HD event).
  • 10.
  • 11. Examples (2/3).
    • The following example was a demo at the Supercomputing ‘08 conference.
    • The conference was in Austin, Texas.
    • The Georgia Aquarium is in Atlanta, about 1000 miles away.
    • Note the smooth video and natural conversation.
  • 12.
  • 13. Examples (3/3).
    • The following example are images of a Yellow Jacket in the SEM.
    • The Yellow Jacket is the mascot of the Georgia Institute of Technology.
      • Not to be confused with the University of Georgia.
  • 14.
  • 15. Tech Talk.
  • 16. What is R&E Networking?
    • Internet for the Research and Education Community.
      • Research Universities
      • Colleges and Teaching Universities
      • Schools
      • Some commercial research labs (e.g. Microsoft Research).
    • Often referred to as Internet2.
  • 17. What is Internet2?
    • National Backbone Network
      • also National Lambda Rail (NLR)
    • Advanced Networking in General
      • PeachNet (Georgia State-wide R&E network)
      • Southern Crossroads (SOX) Gigapop and Regional Optical Network.
    • Umbrella organization for applications communities
      • e.g. K20 Working Group
  • 18. What R&E Networking isn’t.
    • No commercial traffic
      • Unless inter-university
    • Not facebook
      • SOX Peers with Google.
    • Not to be confused with Web 2.0
      • But often utilized in the university community
  • 19. National Lambda Rail (NLR). Internet2 Footprint is similar.
  • 20. This movie taken from the GLIF website http://www.glif.is
  • 21. PeachNet.
    • PeachNet passes within 5 miles of 35 school district offices.
    • SOX connects most of the R&E institutes in the South East to National and International destinations.
  • 22. SEGP.
    • Sponsored Education Group Participant.
    • SOX sponsors PeachNet.
    • Any K-12 District connecting to PeachNet will get connectivity to Internet2/NLR via SOX.
    • Improve performance, enabling access to rich content.
  • 23. Why not Internet1?
    • Slow and unreliable connections, pop-up adds etc.
    • 12 years ago, R&E community faced similar challenges.
      • lack of capacity, routing, etc led to formation of Internet2 organization, Abilene and regional gigapops.
      • R&E Networking launched research into new era.
      • Large corporations build their own networks.
    • We need AT&T, Level3, Qwest, AGL etc
      • Fiber providers
    • But we want a separate Layer 3 service with high capacity connections and direct routing between sites.
  • 24. Performance.
    • Congestion causes packet loss and delay.
    • Interactive applications are harder to use.
    • Even non-interactive applications are slow.
    • Bandwidth is required but not sufficient
      • Also latency, jitter, routing.
  • 25. A Typical K-12 System in Georgia. Severely congested pipes mean long queues in routers. This graph show the delay (in milliseconds) between the clean room at Georgia Tech and a district central office . In the evenings and weekends, delay is 5 milliseconds.
  • 26. A K-12 System Connected to Peachnet. 2.2 milliseconds 2.4 milliseconds This graph show the delay (in milliseconds) between the clean room at Georgia Tech and a district central office .
  • 27. Utilization. More capacity means less congestion Immediately see usage 2-3x previous capacity. District upgraded from 20 Mbps to 155 Mbps (Peachnet).
  • 28. Video-Conferencing.
    • Commercial off-the-shelf products for stability and support.
      • Considered DCRS
    • Opted for High Definition
      • 720p, 1080p.
    • Aim to be vendor independent but Life Size donated several unit.
    • Polycom long-term loan in Observatory.
    • Equipment pricing ranges from $6,500 to $20,000.
  • 29. Beyond the Bandwidth Barrier.
    • Additional capacity is just the first step.
    • What becomes possible if there was almost unlimited bandwidth?
    • R&E networking enables advanced applications for new learning experiences.
    • Technology is secondary.
    • In fact we want students to focus on content, not the technology that delivers it.
  • 30. Keep it Simple.
    • Simple idea - so why isn't everyone doing it?
    • Scalable?
      • Many Universities want to contribute
      • Researchers don’t know what is available to them
    • Sustainable?
      • Part of the solution
    • Researchers are keen to do it.
      • Students
      • Grad students
      • Their own kids
