From The Front Lines: Peeking Inside a MOOC in Progress

For example, students have complained about not being able to complete in-video quizzes when they download the lecture videos. While our instructional team wanted to help them complete this work off-line—many students have very limited Internet access—we could not provide a way to do so. We pressed Coursera support-staff members for a solution, but they could not provide one.

…

My limited ability to make key pedagogical choices is the most frustrating aspect of teaching a MOOC. Because of the way the Coursera platform is constructed, such wide-ranging decisions have been hard-coded into the software—decisions that seem to have no educational rationale and that thwart the intent of our course.

I suspect that this will not be the first time we hear from a MOOC faculty complaining about some sort of failure of the the tech platform. Something important here is that Coursera is commercial company and the platform is closed and proprietary. At least if this were an open platform like EdX or Canvas there would be a chance to add the features that the teachers need to educate their students as they see fit, not as some random engineer or developer tells them it needs to be done.

American Airlines Dumps 35 lbs of Paper By Deploying iPads

“Our Electronic Flight Bag program has a significant positive environmental and cost-savings impact,” said David Campbell, American’s Vice President – Safety and Operations Performance. “In fact, removing the kitbag from all of our planes saves a minimum of 400,000 gallons and $1.2 million of fuel annually based on current fuel prices. Additionally, each of the more than 8,000 iPads we have deployed to date replaces more than 3,000 pages of paper previously carried by every active pilot and instructor. Altogether, 24 million pages of paper documents have been eliminated.”

American is replacing nearly 35 lbs of loose leaf binders with a single iPad as it rolled out the Electronic Flight Bag (EFB). The press release notes the program is fully underway and the paper is gone. That means no more paper updates and loose leaf filing chores for flight crews.1» The FAA-approved EFB uses a specially designed app from a division of Boeing Digital Aviation to manage all of the information and is kept up-to-date electronically.

As we see more and more iPads being used in various professions, it should only be a matter of time until law schools start handing incoming law students an iPad loaded with all of the material they need for their law school education. Or maybe not.

Taking CALIcon13 Live to the Web Using YouTube Live Events, TeleStream Wirecast for YouTube, and Commodity Hardware

We were able to live stream the entire CALI conference on YouTube this year. A lot of folks have asked me about how we did this and that’s what this article is going to cover. Before I get into the nitty gritty of how it all worked I want to make sure to thank the folks at IIT Chicago-Kent for making all of the tech stuff happen. Specifically from the Audio Visual & College Service Center Staff: Jarryd Scott Steimer, David Townsend, Alton Jackson, Sue Jadin, Gloria Juarez, Aaron Ruffin; from the Center for Law and Computers Staff: Sejal Vaishnav, Nisha Varughese, Bill Mette, Mohit Gaonkar, Rudi Buford, Efe Budak, Heather Banks, Greg Morris, Larry Adamiec; and Debbie Ginsberg and Emily Barney from the Law Library. Thanks everyone for making CALIcon13 a great tech success.

One upon a time webcasting a conference live on the Internet took a LOT of effort. Cameras, capture cards, encoders, PCs, a streaming server, and a fair amount of good luck to make sure it all worked. We did it for many years with the CALI Conference for Law School Computing. Eventually we gave up, as it became too difficult to manage especially as we took the conference on the road every year to a different law school. Even something as seemingly basic as pointing a camera at the front of room became difficult especially when you multiplied it across 5 rooms and 4 – 5 sessions per day. Lots of equipment and lots of things to go wrong. We just went back to recording for archives and dropped the live stream.

Earlier this year Google began making YouTube Live Events available to Google Apps for Education organizations. YouTube Live allows you to schedule and stream live video using YouTube’s infrastructure. Using YouTube Live requires having an encoder running on a local computer and a good, stable Internet connection to connect the encoder to YouTube. Once connected to YouTube, the event will not only stream live on YouTube but it will also record to YouTube. The archived recording of the event becomes available on YouTube at the same URL shortly after the live streaming of the event concludes. After testing the product I realized that we might be able to bring live streaming back to CALIcon.

The basic set up for this is pretty straight forward and is well handled by commodity hardware. We used a Canon video camera, Star-Tech USB capture, and Dell laptops. The actual specifics of the hardware isn’t really important since it is more about the features of the hardware. The camera should have composite video and audio outputs. High definition video isn’t really necessary here, it just uses extra bandwidth. The camera’s video and audio outputs were connected to the USB capture device. The capture device was connected via USB to the laptop. The laptop needn’t be a hot rod, just current. The encoding software we used is available for Mac or Windows computers.

With the hardware in place the USB capture device is seen as a USB camera by the encoding software. This allows the audio and video from the camera to be streamed to YouTube. For encoding of the video, we used the free version of TeleStream Wirecast for YouTube. Wirecast proved easy to use and the free version provides enough features to get your stream up and running, especially for most law school events that you might be streaming.

Once we sorted out the hardware and software we were going to use the next thing was making sure that all of the sessions were scheduled on YouTube. 55 sessions were scheduled on YouTube. This gave us event slots that we could connect the encoders to at the right time. We created a separate event for each CALIcon session. This created a YouTube link for each session. The URL was embedded in each session page on the CALIcon website so that the conference sessions could be watched live directly from the CALIcon website. The same URLs embed the archived session video in the session page on the site.

And that is all there is to it. We also recorded the video on SD cards in the cameras for archival purposes. Of the 55 session streams that we launched, we had some timing issues with the first set of sessions that resulted in some short streams, and we had 1 stream that did not record properly on YouTube. All of these videos were replaced on YouTube with the video recorded on the SD cards. Within 4 days of the end of CALIcon13 all of the video for all of the sessions that were recorded was available to all on YouTube and on the CALIcon13 website.

I would recommend that you give this a try at your law school. No matter what sort of recording/streaming solution you are using, I think you’ll find the YouTube Live Events solution useful. If you have any thoughts or questions, please use the comments below or send me an email.

Try Onion Pi To Turn Your Raspberry Pi Into a Wireless Tor Proxy

The do-it-yourselfers at Adafruit have provided step-by-step instructions for turning a Raspberry Pi into a Tor proxy and wireless access point. A good project for users looking to anonymize their Internet traffic, “Onion Pi” requires just a Raspberry Pi, a few standard peripherals, and some work in the command line.
You’ll need a Pi of course, an Ethernet cable, a Wi-Fi adapter with an antenna, an SD card loaded with the Raspbian operating system, and a power supply. You can buy all these from Adafruit in the companys Onion Pi Pack, but the components are pretty standard and could be obtained from many other sources. A portion of sales through Adafruit will go to the Tor Foundation.

This is timely. Sounds like another good way to put a Raspberry Pi to use.

Google Play for Education Accepting Submissions

Google’s submission process requires all applications marked as suitable for K-12 to first pass through a network of non-affiliated educators for evaluation before then being measured against the Play for Education store’s requirements for classroom use. If selected, developer’s applications will be made available to the many pilot programs currently underway across the country

via Engadget: Google Play for Education now accepting developer submissions.

Google Play for Education is getting under way. Seems like Google is doing all the right things to make sure that the apps that get into the special store really belong there.
