Presentation: Keynote - Internet and Education
Presenter: Dr. Vinton Cerf, Google
Scary - more laptops here in this small room than at the big ASTD Hall altogether.
Dr. Alan Merton - President, George Mason U.
Teaching and learning - there is a lot of LEARNING that ought to go on that doesn't relate to a specific teaching function.
We are doing research in PARTNERSHIP.
We are not in passive service - we are community-driven and community-driver.
Long-term vs. short term planning (theme)
Dr. Vinton Cerf, VP and Chief Internet Evangelist, Google
Internet emerged out of educational environment (ARPANET) - 1969
1st 3 network test of internet - Nov 22, 1977
- Most significant milestone
- Took 3 different packet switch and connected using common protocol
- Prove can combine disparate systems
- knew had real technology
By 1999 - demonstrates the collaborative nature of the internet
- Each system is an independent decision to join!
Right now - 625 million+ publicly visible. Not counting stuff behind firewalls and episodically connected (mobile devices, etc)
Mobile telephony grown - 4.1 billion in use.
- 15-20% have access to internet
- Internet services through Mobile still a challenge - due to display size and keyboard design
- We harm ourselves by thinking of using Internet 1 device at a time.
- If mobiles smart enough - can bring mobile and detect a projection system to interact with. Both recognize. Then mobile can go to projection unit for better display. [is this already being done with Bluetooth?]
- Mobiles may be evolving into "little remote controllers"
- Questions asked on mobiles geographically located. Contextually located.
Internet population - 1.5 billion
- Asia representing almost half of the worlds internet population. (657.1 mil, only 17% penetration)
- Implication for use of the net. Interest and culture varies.
- In contrast - North Am. 251.3 Million, 74.4% penetration
Educational uses of the internet
- email - first killer ap. Collaboration, communication, distribution
+ [Is this because it is the system we best understand today? Is this the best tool?]
- Web Sites - blogs, twitter [Don't think Dr. Cerf is a fan.....]
- Social Networks (teachers, students)
- WWW search engines
+ Expunge "teaching" from vocabulary. It's all about "learning"
+ Lesson - information you get on internet needs to be considered critically
+ Your job is to help students think critically about ALL sources of information.
- Innovative interfaces - note I/O discovery
- Navigation systems (GPS, Galileo...)
- Geo-location based services
- Navigation system
Google Tools to assist education
- Google Earth
+ Not simply a device for presentation and query. Will accept information.
+ Applications to place overlays.
+ People can use to present geographically indexed information. Increasingly useful and valuable.
- Google Maps
+ Also has programming interface. Can program and place information over it.
+ Ability to dynamically change information very helpful.
- Together Maps and Earth quite valuable.
- Google Ocean / Google Sky (Google Earth Aps)
+ Undersea topography / Look at the stars
+ Used by scientists to display information about data collected
+ Google Sky - help you find which constellation you are looking at
- Timeline in Google Earth - can show change as function of time.
+ Can present both past and future information in the timeline.
- Utility conveyed by those who use the applications to produce materials.
- The Google Earth tools (incl. Google Mars) valuable discovery tools.
- Anecdote: Student use of Internet/Laptop in lecture hall/class
+ Students using internet to do research during class on the topic.
- Pick any one of your (pick your number) pages
- Evaluate the accuracy and completeness of the page
- Cite resources used to evaluate; criteria
- Required: use of library in addition to online resources.
The JASON Project (National Geographic)
- Getting a chance to do something is a powerful lesson
Internet enabled Devices
- Persuaded there may be many many more devices in future. (internet-enabled surfboard)
Sensor networks - may become extremely powerful sources of information
- IP v6 Sensor net (he has it in his HOUSE)
- 15 network devices,
- Will be running out of addresses for IPv4 soon
- Every 5 minutes - recording temperature, humidity and light levels. Collect over course of a year to adapt to optimize. Real data.
- Commerical product - Arch Rock.
- Can take raw data and help people learn to analyze - key skill!
+ We need to have better feedback on the decisions we make with consumption of power - esp with environment
+ Deborah Estern - Participatory Urban Sensing
-- Can use mobile to track whether you were someplace where you were exposed to toxins.
-- Mobiles can record information using the pictures - location, date, time. Submit to database.
-- Aging relative with mobile and can sense motion (display flip) - you can see whether mobile has moved at all.
We are carrying around information windows AND sensor systems!
- This could be powerful in educational context.
LOTS of things will wind up being networked
- They could be controllable and deliver info through the net.
School use of tech
- Fishler School, Fullerton CA. All 2nd through 8th graders have 1:1 laptops 24/7. All stagg have Promethean Board
- Virtual Labs using "real" instruments.
+ Actions in virtual lab have real-world consequences.
+ [Early example - telesurgery. He's talking about something 1 step removed]
- Collaboration with shared tools (Gtalk, Skype, IM with Google Docs or other shared sites
+ Kids working together to create.
+ Simultaneous edits.
+ Sure beats sending copies around [now all I have to do is convince my co-workers...]
- Integrating tools into lessons learning.
Learning by doing: powerful in all disciplines
- Multiple data centers (replication,responsiveness)
- Dynamic capacity sharing
- Data sharing (latest copy in the cloud)
- Video and audio conferencing with data sharing
- Inter-cloud interactions (new research area)
+ How to refer to other clouds
+ How to refer to data in other clouds
+ How to make data references persistent (unlike URLs)
+ How to protect clouds from various forms of attack
+ What semantics can we rely on with inter-cloud data exchange
+ What notion of object useful for inter-cloud exchange
Don't just think of people using desktop and laptops.
- The kinds of tasks you can expect someone to do are vastly larger than 1 laptop by itself.
- Intended to deploy technology across the solar system.
- Mars Reconaissance Orbiter, Mars Express, Rovers
+ Plan - transmit back to Earth to big 70m dishes via radio
+ Problem: Rover radios overheated. Had to reduce data rate from 28 Kb.
- JPL - had an Xband radio, had to be orbiting asset.
- Rover finds orbiter, orbiter holds onto data into place in orbit then transmit to earth - 128 kB/sec
- Similar way to internet.
- Need to think long-haul (because there are really really big distances between planets). Also have that pesky rotation problem.
+ Licklider Transport Protocol (LTP)
+ Bundle Protocol (RFC 5050)
-- Delayed binding of identifiers
-- email like behavior
- Delay and Distruption tolerant protocol
+ Deep impact testing - October 2008. Didn't lose a packet. Will be going Outbound in summer. Will reload.
+ Space Station testing - 2009 Right now installing the 2 protocols. Will test this summer.
- 3 node network - Earth, Space Station, Deep Impact / Epoxy
+ Scaffold for testing. Probably not be in final network.
- Important part - the standardization.
+ If all "spacefaring nations" adopt them - any previous assets can be used too!
Richer networking could be VERY beneficial.
