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.
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.
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.
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.
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.
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.
High-speed network connection via PeachNet
HD video conferencing.
Numerous researcher providing content.
Also Professional Development and Evaluation component.
Events involve scientists.
Not K-12 outreach professionals.
Seek to bring research-based curricula to K-12 students
Excitement about science.
Philosophy of Science.
Not replacing teachers.
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).
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.
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.
What is R&E Networking?
Internet for the Research and Education Community.
Colleges and Teaching Universities
Some commercial research labs (e.g. Microsoft Research).
Often referred to as Internet2.
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
What R&E Networking isn’t.
No commercial traffic
SOX Peers with Google.
Not to be confused with Web 2.0
But often utilized in the university community
National Lambda Rail (NLR). Internet2 Footprint is similar.
This movie taken from the GLIF website http://www.glif.is
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.
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.
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
But we want a separate Layer 3 service with high capacity connections and direct routing between sites.
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.
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.
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 .
Utilization. More capacity means less congestion Immediately see usage 2-3x previous capacity. District upgraded from 20 Mbps to 155 Mbps (Peachnet).
Commercial off-the-shelf products for stability and support.
Opted for High Definition
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.
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.
Keep it Simple.
Simple idea - so why isn't everyone doing it?
Many Universities want to contribute
Researchers don’t know what is available to them
Part of the solution
Researchers are keen to do it.
Their own kids
Because they want to
Teachers need to know how to use it to further learning.
Georgia Tech enables collaboration among:
Ongoing monitoring, analysis, feedback, and support through:
Extensive formative evaluation
Annual summative evaluations
Longitudinal studies of students in participating districts during the program and two years after students’ graduate
Formative assessment tied to appropriate performance standards and measures
Quasi-experimental research designs (i.e. comparison group studies where strict randomization is not possible)
Inputs Activities Outputs Outcomes Impact Leadership and committed resources in Barrow, DeKalb, and Putnam School Districts Direct 2 Discovery STEM teachers paired with faculty and education experts collaboratively develop and deliver learning. Increase bandwidth to schools and connect to R&E network Teachers experience measurable growth in content, pedagogical, and pedagogical content knowledge Provide teacher professional development through local universities equipment and resources provided to participating districts Students demonstrate increasingly greater success in STEM Plan, build, and support the necessary cyber-infrastructure Provide classroom resources and equipment
Implement STEM teaching
Experts in Science Education, Educational Technology, Engineering Education, and Math Education Every STEM student learns more richly than through traditional instructional methods. University faculty/researchers
Teachers talk about achievement
Engagement and excitement
Formal proof will take years of tracking and study.
More Examples and Development.
Aerospace Engineering, Astronomy, Biology, Chemical Engineering, Robotics …
Abbotsleigh school in Sydney, Australia.
Killina school in Rahan, Ireland.
Also U.K., Italy …
Muse, Janet collaborate.
Events so far have been informal. Seeking grants to develop more formal courses and evaluation.
Spin-Off for SEM/FIB training.
In the following example, a student asks a question but unlike most classes, an expert can be instantly consulted.
Also note large projected 6’ screen is the same as the screen connected to the FIB on a 20” monitor.
Not shown is additional large screen 50” monitor showing operator in lab.
Direct-to-Discovery brings scientists and their research into K-12 classrooms from the convenience of their labs using high-speed networks and HD video conferencing.
Face-to-face is best.
Miracle of hands-on learning.
Not always practical.
More than distance learning or on-line education
Augmenting book learning.
Are we ready for global education?
HD allows student to focus on the content, not get distracted by technology.
Your content for Georgia or SOX region students. Our content for your students.
Also interested in collaboration between researchers which would include RET/REU.
Build a D2D module around it.
Especially about money for equipment and graduate students.
