NSF EdTech

Reports on reporting about what we're learning about learning (and, of course, teaching about teaching) at the Huffington Post's 7 Cyberlearning Technologies Transforming Education | Aaron Dubrow
...NSF funds basic cyberlearning research and since 2011 has awarded roughly 170 grants, totaling more than $120 million, to EdTech research projects around the country.

The speakers in the lecture series, all leading cyberlearning scholars, ... represent the forces transforming what education may look like in the future.

1. Classroom as Virtual Phenomenon: RoomQuakes and WallScopes

HelioRoom simulates the orbital motion of the planets in the Solar system on a set of synchronized computer displays situated on the walls of the classroom, with planets "orbiting" around the periphery of the room. ...

... RoomQuake, an earthquake simulation system where the classroom itself becomes an active seismic area. At unpredictable times throughout the unit, rumbles emanating from speakers attached to simulated seismographs signal to the class that an earthquake is occurring....

Students rush to terminals around the classroom, read the data from seismograms .... Over the course of six weeks and dozens of earthquakes, students discover a "fault line" emerging. ...

Tablets adjacent to the walls of classrooms serve as viewports into an imaginary space inside the walls filled with the virtual fauna in Wallcology. ...

2. Games for Good: Learning While You Play

... in the game "Citizen Science," created by Squire and his team, players help restore Lake Mendota, a real lake in Wisconsin that, in the year 2020, has become polluted. As players explore the landscape, they take water samples, interact with a virtual, simulated watershed and talk with stakeholders....

... for a game that might reach even broader audiences, Squire and colleagues created Progenitor X, a zombie-themed tissue engineering game. In Progenitor X, players learn about the relationships between cells, tissues, and organs while trying to survive a zombie invasion. ... As a member of The Progenitor X Defense Force, you are a part of a highly trained squad of scientists who use highly advanced bio-medical technology to locate, seek out, and treat infected humans to contain the threat. ....

"These projects are not only using technologies that only recently became possible. They also build on decades of excellent research on how people learn," said Chris Hoadley, the program officer at NSF who leads the Cyberlearning program. "I believe it's only by advancing technology design and learning research together that we'll be able to imagine the future of learning."...

3. Teaching Tykes to Program: Never Too Young to Control a Robot

... Bers described her latest project, the KIWI robotic kit (subsequently renamed KIBO), which teaches programming through robotics, without screens, tablets, or keyboards. Using KIBO, students scan wooden blocks to give robots simple commands, in the process learning sequencing, one of the most important skills for early age groups. By combining a series of commands, kids make the robot move, dance, sing, sense the environment or light up....

4. Virtual role-play and robo-tutors

... Virtual role-play - where learners engage in simulated encounters with artificially intelligent agents that behave and respond in a culturally accurate manner - has been shown to be effective at teaching cross-cultural communication.

"You learn by playing a role in a simulation of some real life situation"

"We found in our military training that when soldiers use this approach, once they get into a foreign country -- let's say they're sitting down with local leaders -- they feel as if it's a familiar situation to them... Moreover, the software could address the shortage of qualified teachers able to teach Chinese, Arabic and other less popular languages... The first Web-based course was tested last year via Virtual Virginia, a statewide virtual school program, and received overwhelmingly positive ratings from the students....

5. Tools for Real-time Visual Collaboration

... "Computers have been individualistic devices," said Ramani. "But a new class of technology is emerging that allows us to engage in our individual learning process and also in a collaborative process." SkWiki ... allows many participants to collaboratively create digital multimedia projects on the web using many kinds of media types, including text, hand-drawn sketches, and photographs....

6. Fusing data collection, computational modeling and data analysis

Simulation and modeling have come to be regarded as the "third pillar" of science... ... By embedding simulations and sensor data collectors in the classroom, Dorsey and Wilensky are able to aid students in gathering, visualizing and analyzing data from multiple sources. A principal innovation of InquirySpace is the integration of the Concord Consortium's CODAP data exploration software with the modeling environments. This integration enables students to plan extended investigations of models, to do sophisticated analyses of the model runs, and to engage in arguments from evidence. ...

7. Virtual Worlds and Augmented Reality: Increasing ecological understanding

... Two decades ago, with funding from NSF, Dede started investigating head-mounted displays and room-sized virtual environments... At the beginning of the two to four week EcoMUVE curriculum, the students discover that all of the fish in a virtual pond have died. They then work in teams to determine the complex causal relationships that led to the die-off. The experience immerses the students as ecosystem scientists. ... At the end of the investigation, all of the students participate in a mini-scientific conference where they show their findings and the research behind it.
I don't know how well the experiments will scale up, but I would like to note that all of this seems to require ending the teaching-to-the-test that the last few posts have been about. They all seem to require teamwork, but none of them have much to do with traditional lectures. All of them have a learn-by-doing framework, where the computer facilitates the doing -- or even provides the universe for that doing to be done in.

3D Printing

The school's YouTube channel just uploaded a video, at Link 3D Printing at Hamilton Central - YouTube
Thanks to a gift from the Emerald Foundation, 3D printing is now a reality. Please check out this short video (sorry no sound), to see what we have printed so far and to see the assembly of a mechanical hand that can be used with children that may be missing some or all of one of there hands.
For those who haven't been following the 3D printing developments, here from two years ago is Dad Uses 3D Printer To Make His Son A Prosthetic Hand (VIDEO)
Leon McCarthy was born without fingers on his left hand, but with some help from his dad, he can now draw, pick up food and hold a water bottle using a homemade prosthetic.
CBS Evening News reports that instead of paying tens of thousands of dollars for a factory-made prosthetic hand, the 12-year-old's father, Paul McCarthy, printed one.
The Massachusetts dad had spent two years searching for affordable ways to give his son a prosthetic. Finally, he found inspiration on the Internet. He told Fox that he found a YouTube video detailing the work of Ivan Owen, who used a 3D printer to create a prosthetic hand for a 5-year-old in 2011. Following in Owen's footsteps, McCarthy used a 3D printer purchased for his son's school and began working on the hand with his son.
Earlier this summer, NPR reported that McCarthy used online directions from Owen to put the prosthetic hand together and -- with a little trial and error -- created a hand that Leon was able to try.
It's not just humans: 9 Animals Whose Lives Improved Thanks to 3D Printing
the fifth-grade students of May Howard Elementary School in Savannah, Ga., went well beyond your average class work when they designed and built a 3D-printed prosthetic for an injured box turtle appropriately named Stumpy.
(That slide show ends with a 3D printed replacement beak for an injured eagle.) And of course it's not just prosthetics. 3D Printing: Are You Ready for the New Decentralized Industrial Revolution? | WIRED
In the field of medicine, 3D printing of complex living tissues, commonly known as bioprinting, is opening up new avenues for regenerative medicine. ... This cutting edge technology in conjunction with stem cell research is likely to revolutionize the made-to-order organs, cutting across the transplant waiting lists.
The Aerospace industry, an early adopter of this technology, is already designing small to large 3D printed parts saving time, material and costs.
The Automobile world is already witnessing crowd-sourced, open-source 3D printed vehicles driving off of the showroom floors...
And yesterday's news included Scientists develop superfast 3D printed octopus submarine | 3D Printer News & 3D Printing News... And so on, and on and on.

So, is this a good thing to be doing in school? I think so. Will it improve test scores? Um... probably not, which for me is one more reason for not over-emphasizing test scores. Will it measurably help students get Ready For Jobs? (I.e., has the prospective unemployment rate among HCS graduates ten years hence been measurably lowered?) Some will say yes, but I think probably not. Why, then, is it a good thing to be doing in school?
That's not an easy question...but I think that I think that school, to a significant extent, ought to be about feeding dreams. So personally I approve. Yay!

Khan on Future Learning

Courtesy of the KhanAcademy guy, creator of all those thousands of two-to-ten minute lectures with questions attached, we have "Future Learning" (from Good Magazine)
with a number of interesting thoughts.
  • "The lecture is only valuable if you have that question in your brain..."
  • "The school is gonna be one or two Really Big classrooms..."
  • "If a bunch of kids want to take a month or two off to build a robot, go ahead -- you're not going to miss class, there's no such thing as missing class..."
  • "The teachers are fountains of knowledge, experience, mentorship, humanity -- as opposed to fountains of a scripted lecture."

Or then again, maybe not.

Telepresence Now

Consumer and Education: Student Attends School Via Robot | Robotics Trends
What's most remarkable is how unremarkable this technology is viewed by his classmates. In a class of 7-year-olds raised on video games, avatars and remote-controlled toys, they don't see a robot. They just see Devon.
Just before class one recent day, a girl leaned toward the robot to tell Devon the joke making the rounds at school: Why did the boy eat his homework? The teacher told him it was a piece of cake.
While making get-well cards for him during a hospital stay last year, his classmates all drew him as a boy, not a bot.
Maybe it's the New Normal, or will be in another decade...

Or then again...

On Playground Assembly

Several people helping assemble the HCS playground equipment on the 12th and 19th (links to both day's pictures here) commented that it was repetitive and awkward. True enough; it was the sort of thing that ought to be done by a robot. So I look at assembly line robotics on YouTube:
Well, clearly we're not quite ready to assemble playground equipment on site. Engine assembly we can do; there's no obstacle in the complexity or mechanical force (or repetitiveness, or awkwardness). But flexibility is a problem. Still, consider last month's "Baxter" announcement by Rethink Robotics, as in Rethink Robotics: Meet Baxter - YouTube
Meet Baxter, a revolutionary new category of Robot from Rethink Robotics that is capable of applying common sense behavior to manufacturing environments. Affordably priced, versatile and safe enough to work shoulder-to-shoulder with people, Baxter robots redefine how small, mid-size and large domestic manufacturers use automation to compete with manufacturers in low-cost regions of the world.
We're getting there; repetitive assembly will all be done by robots, by and by.
Or then again, maybe not.

Thymio II Education Robot

Hmm..did I mention robotics lately? Your Kid Wants a Thymio II Education Robot - IEEE Spectrum
Yes, there's a trailer hook. So you can stop worrying about that. And those "mechanic fixation" points are Lego compatible. To program Thymio II, you can use a nifty graphical interface, or a simple programming language called Aseba that's similar to Matlab. And oh hey did we mention that this thing is open source from source code to hardware? 'Cause it is.
Seriously, $100 seems very cheap for a platform like this. It's cheap enough that a $1,000 grant could outfit an entire classroom with robots that are colorful, versatile, fun, and can be tackled with a GUI before graduating to writing code.
Of course there are even cheaper systems, like the rubber-band powered Walking paper Robot - YouTube.
Surely every kid should play with robots.
Or then again, maybe not.
