Thanks to funding from the New Venture Fund and support from The Bill & Melinda Gates Foundation, Medium has launched Bright, pop-up publication about innovation in education."

Check it out here. I bet it will have interesting stories to feature on High Five and Vialogues.

As an aside, it looks great on mobile.

Details for the talk are below. I will blog it for folks who are interested.

Learning Analytics Seminar Series
Jack Mostow, Carnegie Mellon University
Horace Mann Hall 144
April 2, 10am

Title: How Can We Learn from a Reading Tutor that Listens?

Abstract: Project LISTEN’s Reading Tutor listens to children read
aloud, and helps them learn to read. It displays text on a computer
screen, uses automatic speech recognition to help analyze a child’s
oral reading, and responds with spoken and graphical assistance
modeled after expert reading teachers but adapted to the limitations
and affordances of the technology. The Reading Tutor logs its
interactions in detail to a database that we mine in order to assess
students’ performance, model their learning, and harvest
within-subject experiments embedded in the Reading Tutor to compare
alternative tutorial actions. This talk will illustrate a few of the
Reading Tutor’s tutorial interactions, student models, and
experiments.

Looking for primary sources to use in your teaching of 9/11? Check out over 3,000 hours of news coverage from September 11, 2001 to September 17, 2011 at the Understanding 9/11 TV News Collection. It contains broadcasts from major U.S. news outlets as well as international news channels (e.g., BBC, CCTV3, CBC, AZT, NHK).

There are also some Vialogues that were created back in 2011 for the 10 Year Commemoration:

September 11, 2001 - As It Happened - The South Tower Attack

NBC News Coverage of September 11, 2001

Muslims' America: Growing-up Post 9/11

Obama Salutes Service of '9/11 Generation'

David Letterman reacts to 9/11

I hope that for next year we can lead/participate in activities that result in a more powerful collection of 9/11 vialogues for educators.

 

A Faster Web Experience with the Picture Element

Submitted by Hui Soo Chae on Wed, 09/03/2014 - 6:44am.

Check out this article from Ars Technica about a new HTML element that will make browsing the web much faster.

It's a great story of how a small group of developers (at the Boston Globe) engaged a broader community of developers and then some established institutions (as well a crowd funded campaign) to solve the problem of slow loading responsively design websites.

Here is how it works:

When the browser encounters a Picture element, it first evaluates any rules that the Web developer might specify. (Opera's developer site has a good article on all the possibilities Picture offers.) Then, after evaluating the various rules, the browser picks the best image based on its own criteria. This is another nice feature since the browser's criteria can include your settings. For example, future browsers might offer an option to stop high-res images from loading over 3G, regardless of what any Picture element on the page might say. Once the browser knows which image is the best choice, it actually loads and displays that image in a good old img element.

 

Tough Times for the Class of 2008

Did you graduate college in 2008?

According to a story from Vox the Class of 2008 had the misfortune of graduating right in the midst of the Great Recession. For example, they have higher unemployment and lower incomes than other college graduates.

Class of 2008 Unemployment Rate

Class of 2008 Salary

The situation is even worse if you were a social science or humanities major:

I was invited at the last minute to participate in the following workshop:

Fostering Innovation and Improvement in Education: the Contribution of Longitudinal Information Systems

An international workshop organised by the
OECD Centre for Educational Research and Innovation (CERI)

New York City, United States, 30 June – 1 July 2014

Specifically, I was asked to moderate a session on "next-generation systems and promising features in the R&D pipeline."

Speakers:
Nelson Gonzalez, Declara
Gerri Burton, New Learning Ventures
Chris Lohse, Renaissance Learning

Speakers will present "promising ideas about what next-generation systems could look like in the coming years by incorporating technological innovations in the R&D pipeline as well as new business models to overcome the traditional institutional barriers around data use."

 

Chinese Restaurant vs Indian Buffet

Manav introduced me to this paper on the Chinese Restaurant Process (CRP) in the context of recommendation of learning resources across multiple EdLab resources:

Blei, David M., Thomas L. Griffiths, and Michael I. Jordan. "The nested chinese restaurant process and bayesian nonparametric inference of topic hierarchies." Journal of the ACM (JACM) 57.2 (2010): 7

I think it provide a nice overview of supervised learning methods and unsupervised learning methods, as well as parametric and non-parametric models.

During my "exploration" (i.e., struggle to understand CRP), I also came upon the Indian Buffet Process:

Griffiths, T. L., & Ghahramani, Z. (2011). The indian buffet process: An introduction and review. The Journal of Machine Learning Research, 12, 1185-1224.
(I did not make it past the introduction of this paper).
