Statistics Education Application for the iPhone
Submitted by Aldon Hynes on Mon, 11/30/2009 - 16:32At the Digiday:APPS conference in New York City last August, Teaque Lenahan, an Associate Partner, at Gravitytank presented the results of some of their recent research. He showed a clip of some of the people that they had spoken with, including a principal talking about giving kids iPhones instead of text books. I really liked this idea. While I am leaning more towards other mobile devices as the best development environment, iPhones do have a lot of appeal, and I could imagine some students really enjoying doing their studies on an iPhone instead of from a textbook.
So, it was with great interest that I received a press release last month from Michael Mayrath of GetYaLearnOn. They had just launched a pilot test of an application for learning statistics on the iPhone at Abilene Christian University. I corresponded with Dr. Mayrath to get a better understanding of what they were doing. It seems there is no dearth of educational apps for iPhones. What makes their app stand out?
What makes GetYaLearnOn’s approach exemplary is that Dr. Mayarth has his PhD in Educational Psychology and their director of Research and Development, is finishing up her doctorate in Educational Psychology as well. Dr. Mayarth did post-doc work at Harvard’s Graduate School of Education on Virtual Performance Assessment under Dr. Chris Dede, the Timothy E. Wirth Professor in Learning Technologies. Besides his work on virtual performance assessment, Dr. Dede is working on Developing Multi-User Virtual Environment (MUVE)-based ecosystems science curriculum modules for middle school. I have long been a fan of multiuser virtual environments for education and would love to see such an environment eventually available at the school my daughter goes to.
Dr. Mayarth also suggested checking out The Cambridge Handbook of Multimedia as another good starting place for information on instructional design in multimedia learning environments. He also noted that his Masters was an evaluation of a two year pilot program that examined best practices for using Second Life in the classroom.
The focus on assessment of learning tools, I believe to be critical, and I was very interested to hear about their focus on this as part of developing their application.
I must admit that I’m not an iPhone user and have not had a chance to kick around GetYaLearnOn’s Statistics Application for the iPhone. However based on the discussions I’ve had with Dr. Mayarth, it seems like they are approaching using mobile devices in education in ways that the principal in the Gravitytank presentation could only dream of. Hopefully, it will help establish a new standard on how educational applications will be developed.
#trinblogwar Captain Futurist and the Innovators
Submitted by Aldon Hynes on Mon, 11/30/2009 - 11:19This evening, I will be speaking at Colin McEnroe’s class Course on New Media and Old Media at Trinity College. I’ve spoken at his class in other years, typically starting from my role in various political campaigns in Connecticut. Yet the discussions often would go off in many unrelated directions. This year, I’m not currently working on a campaign, and I’m finding I’m talking more and more as a futurist.
I’m not a big fan of futurists. I don’t think any of us can really predict the future. We can observe certain trends and talk about how these trends might change things, but that is about it.
For me, there are several important trends that should always be considered when thinking about technology and the Internet. Perhaps some of it is the Dance of Shiva, tearing down and building up again. One trend, is disruption. Someone will always come up with a new idea that challenges the ideas of the status quo. It is disruptive technology. It follows the technology adoption lifecycle. The first adopters are the innovators, the people that live for this sort of disruption, the visionaries, and perhaps real futurists. They rush into each new potential disruption, play with it, and in some cases push it forward to the point where the early adopters and then early majority come on board. Other potential new disruptions don’t live up to their potential and end up becoming fuel for other ideas of potential new disruptions.
This is the space I live in, the work I like to do. Let’s find some new technology, technology that isn’t ready for the early majority, technology that the late majority will shun and lampoon, and work with it until the early adopters and the early majority start playing with it. Then, it will be time for the next innovation.
This takes me to another trend, which I believe good innovators should be looking at, which is convergence. When someone comes up with a good idea, other people will copy it, they will riff off of it and create their own versions of the same thing. Eventually, the best implementations will capture the attention of the early adopters. These early adopters will try different systems and they will want the systems to interoperate and to converge. Look at email. In the early days of email, you had CompuServe, you had Prodigy, you had SMTP, You had X.400; the list went on and on. However, SMTP was the simplest and most open way of connecting, and eventually it all converged on SMTP. You are seeing the same sort of thing with instant messenger systems; AIM, Yahoo, MSN, Google and others. Google is based on XMPP which is perhaps the open standard for instant messaging like SMTP was for email.
So, as I look at disruptive technologies, I like those that are based on open standards and can easily be developed for and expanded upon. It is part of the reason I like Google’s Android and Nokia’s Maemo better than I like Apple’s iPhone.
With this in mind, I also suggested to Colin that his students should look at Portable Contacts and DandyID as well as OpenID and Open Social. One of the diversions we might get off on is how we understand our digital identities. Colin asked his students if some of these are ‘safe’ ways of managing one’s online identity. Too often, it seems like people are more concerned about hiding part of their identity, instead of sharing their identity the way they want it to be shared.
Personally, I think the best way to control one’s online identity is to be open and share it widely. If not, Tom Friedman’s warning may come into play. “On the Internet, either you do it, or someone else does it to you.”
This leads to the area that does not get enough attention by innovative geeks; what sort of social impact these disruptive technologies might have. They typically shun the discussions that always take place around one technology or another about whether it is a ‘good’ technology or a ‘bad’ technology. These are the topics for freshman college classes, which rapidly become tedious. Us geeks always think of technology as being neutral. It can be used for good or for ill.
Yet this is where the political side comes in and it ties nicely back to Colin’s class. What are the real implications of technological change? In 2004, Robin Sloan and Matt Thompson released a flash video entitled EPIC 2014. It looks at the effect of technology change on the news media. It is bleak. It was later updated to Epic 2015 which is a little less bleak and a little more up to date.
In EPIC 2015, they predict the Wifipod, an iPod with Wifi and a camera. It was a pretty good guess at the iPhone. They also predicted the Google Grid, where all kinds of content gets stored and shared. In many ways, it seems like Google Grid is their early guess at Google Wave.
I like playing with GoogleWave because the underlying technology is very open. I have my own GoogleWave server and I’ve been working on porting the QWaveClient to the Nokia N900
In the evolution of EPIC, they also talked about Google gathering contextual information from the web to build the personalized news. There are two companies that I’m keeping an eye on right now that seem to be focusing on this, Clara and Peer 39. They are mostly looking at it from a marketing or advertising framework.
Another thing I found interesting in EPIC 2015 was Microsoft’s NewsBotSter. The latest stories of Rupert Murdock trying to strike a deal with Microsoft so that news from Murdock owned sites would only appear in Bing. Jeff Jarvis has the best analysis of the Murdoch Madness I’ve seen so far.
Meanwhile, the Federal Trade Commission is holding a two day workshop entitled From Town Crier to Bloggers: How Will Journalism Survive in the Internet Age?. I had hoped to be able to attend, but my schedule is just too busy right now. Murdoch will be speaking as will Arianna Huffington, who is attempting to approach the news from a slightly different angle than Murdoch. It should be a great workshop, and I hope to catch some of it online.
This leads me to another topic I wanted to talk about with Colin’s class. As more people communicate real time via the Internet, as they join in more of a conversation, even if some of the conversation is about what they did during Thanksgiving, or the traffic coming home, it has a great possibility to impact the way government works.
So far, much of political activism has been about elections. But more and more of it, I believe, will be about more direct citizen involvement in all levels of government. At the local level, See, Click, Fix, is a great new way for citizens to make their voices heard at city hall. Systems for submitting comments to rules making bodies, like the FTC and FCC are evolving and improving and more people can get involved this way as well.
In October, I wrote a blog post about submitting my first comment to the FCC. I wrote a follow up about submitting comments to the FCC based on some of the feedback I received. I also submitted a comment to the FTC workshop; initial thoughts, almost final draft, and submitting the final comment.
One final thought about eGovernance; as more and more people get their information online, I expect we’ll see better information coming out of the government about what they are doing. I get emails from the Connecticut Attorney General’s office, as well as various parts of the Department of Justice about what is going on in their areas. Various agencies, elected officials, candidates and advocacy organizations are now sending their press releases and media advisories to CT News Wire a Google Group I set up for them to send their information to, in hopes of reaching bloggers, citizen journalists, and anyone else interested in this sort of information. More and more raw data is becoming available online and this has lots of implications for those interested in computer aided reporting.
I’m sure there will be plenty of other interesting thoughts shared during the class. Maybe some of them will be shared with the trinblogwar hashtag. Maybe I’ll even try to CoverItLive.
What do you think?

Building #QWaveClient for the #N900
Submitted by Aldon Hynes on Sat, 11/28/2009 - 09:43Yesterday, I wrote a blog post about setting up a development environment for a Nokia N900. I spent most of the day with family, enjoying some rough weather out on Cape Cod. However, it was windy and rainy outside and I did find some time to explore a little bit more in my effort to build QWaveClient for the Nokia N900.
Warning: The following content is very geeky. If you’re not a geek, skip to one of my other articles.
Building the Perfect Cellphone: the #iPhone, #droid and #N900
Submitted by Aldon Hynes on Fri, 11/27/2009 - 11:01At the most recent Woodbridge Board of Education Meeting, Superintendent Stella spoke about the school’s commitment to constructivist education “which argues that humans generate knowledge and meaning from their experiences”. When my eldest daughter was born, I busily read Piaget, and I told my daughters that they were free to play any computer game they could write.
Fiona, my youngest prefers broadcast media to computer games, so it should be no surprise that she has her own radio show. Sometimes, as she watches television, I hear ads for Build A Bear workshops, which as much as I dislike stores in malls that advertise on children’s televisions, the idea of building one’s own toy has always appealed to me.
It is with this in mind that I wrote my blog post about the Nokia N900. I want a cellphone that I can build my own applications on. Friends have recommended that I start developing for the iPhone, and other friends have done so, but have spoken about many difficulties they’ve run into. I haven’t made any effort at developing for an iPhone.
I thought that the Android might be the platform I want to develop on. I downloaded an Android SDK onto my Linux laptop and tried running that. I got far enough to start up the Android Emulator, but not much further. I also tried setting it up on my Vista laptop, but haven’t gotten to the point of starting successfully starting the emulator.
With that, I moved to the N900. First, I tried installing with the maemo-sdk-installer.py. Unfortuantely, it did not recognize Ubuntu 9.10 (Karmic). I also tried following the instructions at http://maemo-sdk.garage.maemo.org/install-ubuntu.html but could not get that to install. It may have simply been that the repository was down.
So, I attempted installing using the instructions at http://wiki.forum.nokia.com/index.php/Maemo_5_SDK_installation_for_beginners. This page provides very good details and I ran through step after step without major problems. I will note that they say you must close the terminal window after you create your Scratchbox userid. I failed to do this and had lots of different problems getting my userid to work in Scratchbox. After several different attempts, it finally started.
Following through the steps, I finally got it to install and to run properly. The final hurdle I had in setting up the emulator was that it defaults to setting the nameserver to 127.0.0.1. Since I didn’t have a nameserver on my laptop, I couldn’t find any websites. I went into the /etc/resolv.conf file, put in a valid nameserver and everything started working quite nicely.
Currently, this is working just in X86. The N900 uses an ARM CPU, which the qemu program should be able to emulate. However, I’m currently getting core dumps when I try to run in ARM mode. This means that I probably won’t be able run any binaries for the N900 yet.
However, I should be able to do some software development. The documentation with the Android recommends using Eclipse, and I’ve downloaded this and kicked it around a little bit. There are a bunch of other projects that I want to use Eclipse on as well. The other development environment that I want to kick around is QT. I’ve installed QT on both my Linux laptop and my Vista Laptop, and I’ve built a couple sample applications.
One project I’m interested in playing with is QWaveClient. I’ve been running the Windows binary on my Vista machine, connecting to my FedOne server. One of my next projects will be to try and compile QWaveClient for the N900.
All of this fits into my interests in lifestreaming and playing with real time data. How can this integrate with tools like Skype, IM clients, Twitter, StatusNet and so on? Can I use something like DataTurbine on the N900? Can I feed data from the phone calls and text messages that I send and receive into a DataTurbine of LifeStream?
There are plenty of interesting things to explore on the N900 and right now, I’m doing it all from emulation mode. So, are you looking at a cellphone where you can construct your own applications and experience? Let me know how it is going.
