The answer to the question posted by the authors is a qualified "yes". They write that nuanced behaviours may only become apparent when a massive number of cases is considered. Additionally, data sets that are able to have fine-grained feature sets are able to make better predictions. But it's no walk in the park, it still takes a lot of expertise to develop the algorithms, and it's expensive. (Note - I haven't cited this source before - it should be open access, but sometimes things look like they're open access when I'm working in my office, but are not open access when I'm clicking on the link from home,. so if you have problems, please tell me).

TwitterChat: Balancing the Urgency of Revenue Performance with Mission and Quality Online – May 27

Online learning update by Ray Schroeder - Wed, 2015-05-20 02:12

by Ray Schroeder, Josh Kim (Dartmouth / Inside Higher Ed), Katie Blot (Blackboard), Debbie Cavalier (Berklee)

Challenged by complex and shifting funding models, higher education faces a growing urgency to balance mission and product mix to keep things afloat as enrollments and state funding decline. Adding to this complexity is the growing tension in the marketplace in which the value/currency of traditional degrees are challenged by micro-credentials and the emergence of CBE. How can institutions address these crises? Join UPCEA for this timely TweetChat by using the hashtag #HigherEdAhead on social media as online education leaders share experiences and resources and respond to your questions. A live question and answer session will occur on May 27th from 2-3PM EST.

American Universities Provide Laptops, Make Online Courses More Available

Online learning update by Ray Schroeder - Wed, 2015-05-20 02:09

BY DEJAN LESICAR, Plymouth Daily News

Having a laptop is especially crucial when it comes to online degrees – while having a laptop or desktop on campus makes a student’s life much easier, taking a distance course without one in our day and age is nigh impossible. Different online schools organize their laptop programs differently. Some, like Independence University, provide a new laptop on enrollment and allow the student to keep it in case he or she manages to successfully graduate. Some include laptops into their payment plans, aiming to help those students who are incapable to pay a rather hefty cost of a new laptop upfront.

Lynn University, American College Dublin To Offer iPad-Powered Online MBA

Online learning update by Ray Schroeder - Wed, 2015-05-20 02:09

by University Herald

As soon as fall 2015, students earning their MBAs at American College Dublin (ACD) will be able to take up to half of their required credits through iLynn, Lynn University’s award-winning iPad-powered curriculum. The program will offer students the flexibility to learn online in addition to taking classes at ACD’s campus. “Students at American College Dublin will now have mobile access to Lynn’s MBA curriculum, which includes interactive course materials, videos and other rich content,” Gregg Cox, vice president for academic affairs at Lynn University, said in a statement. “It is a highly personalized education with small class sizes and unlimited use of next-generation collaboration tools.” Lynn has been using these mobile technologies on its campus for the past two years to improve student engagement and reduce the cost of traditional textbooks by up to 95 percent.

New Consortium’s Mission: Improve Liberal-Arts Teaching Online

Online learning update by Ray Schroeder - Wed, 2015-05-20 02:02

by Jeffrey Young, Chronicle of Higher Ed

Four liberal-arts colleges on Monday formed a consortium to share information about their experiments with online education, and more members may soon join in. The focus is not on bringing down the cost of education, but on improving online-teaching projects — whether all-online or hybrid courses — by sharing experiences and collaborating. The premise is that liberal-arts institutions have goals and methods for going online that are different from those of research institutions. “There’s a steep learning curve to figuring out how to use this technology with our students, and with our teaching style,” said Douglas Johnson, an associate professor of psychology and director of the Center for Learning, Teaching, and Research at Colgate University, a founding member of the group. By working together, he said, “we can save each other from reinventing wheels.”

Telepresence Helps Universities Connect Virtual Students with Campus Life

OLDaily by Stephen Downes - Tue, 2015-05-19 21:20
Display


Tanya Roscorla, Center for Digital Education, May 19, 2015

This is an application of technology I'm not so sure of. The idea is to give virtual students the feeling of actually being on campus. So the the University of North Carolina at Chapel Hill has set up live video feeds their faces on tablets mounted on top of telepresence robots they remotely move around the stage and auditorium. In another university where the same technology is being implemented, "The professors didn't have to change their curriculum or even touch the robot, and after the first three weeks of use, Mathews didn't need to supervise or be involved." It seems to me that if you're going to spend that much money - the units cost $2400 per - you should mount the on a quadracopter drone and give them real freedom of movement. See also this item.

Do we actually want to close the achievement gap?

OLDaily by Stephen Downes - Tue, 2015-05-19 18:20


Ewan McIntosh, edu.blogs.com, May 19, 2015

I'm not sure exactly what the "achievement gap" is supposed to be - if I look at my life, do I have an "achievement gap" with respect to Jose Bautista? Or Twitter newb Barack Obama? Having said that, I'm generally in agreement with Brian Boyd's suggestions as summarized by Ewan McIntosh (quoted):

  • remove the traditional, and non-sensical academic/vocational divide
  • start from the ground up, in the early years
  • (stop streaming)... there is no research that supports setting
  • teachers must have opportunities to talk about learning and teaching
  • cooperation instead of competition between departments, school types, ages, stages, and sectors

I would also argue, with McIntosh, that collaboration with business to support education - especially primary education - is fraught with risk.

The Online Paradox at Community Colleges

Online learning update by Ray Schroeder - Tue, 2015-05-19 02:04

by the Hechinger Report

Two weeks ago I wrote about the overwhelming research evidence that community college students aren’t doing as well in online classes as they are in face-to-face traditional classes. Students are failing in higher numbers and getting lower grades. That remains true, but it isn’t the whole story. Peter Shea, who is the associate provost of online learning at the University of Albany—SUNY, contacted me to share his research findings. Community college students who take online courses are more likely – 25 percent more likely to be exact – to complete their two-year associate degree or some sort of certificate than students who didn’t take any online classes. Not only are online course takers more likely to graduate, they’re more likely to graduate sooner than students who don’t take any online classes, Shea also found. He presented this research in a working paper at the American Education Research Association conference in Chicago in April 2015. “It’s a bit of a paradox,” said Shea. “They’re doing worse at the course level, but at the program level – despite lower grades – they’re finishing.”

How to Dramatically Slash the Cost of College Education

Online learning update by Ray Schroeder - Tue, 2015-05-19 02:04

by Sramana Mitra, Huffington Post

The exorbitant cost of higher education is a recurrent topic of conversation, concern, and discontent these days. Against that backdrop, an announcement from edX and Arizona State University caught my attention last week. ASU and edX announced a program called Global Freshman Academy: The Global Freshman Academy (GFA) will give learners anywhere in the world the opportunity to earn freshman-level university credit after successfully completing a series of digital immersion courses hosted on edX, designed and taught by leading scholars from ASU. By allowing students to learn, explore and complete courses before applying or paying for credit, the Global Freshman Academy reimagines the freshman year and reduces academic and monetary stress while opening a new path to a college degree for many students.

Human connections important for online courses

Online learning update by Ray Schroeder - Tue, 2015-05-19 02:02

By Tara García Mathewson, Education Dive

New research into the most effective elements of massive open online courses and other digital learning models find the human elements to be critical. eCampus News reports peer interaction improves outcomes and instructor input, through course design or the actual teaching and facilitation of course concepts, is essential. The report also covers the evolution of online course technology, discussing the currently emerging “fourth generation,” which includes adaptive learning and competency-based models, according to the article.

Creating a Culture Conducive to Integrative Learning

Online learning update by Ray Schroeder - Mon, 2015-05-18 02:03

by Louis E. Newman, et al; Tomorrow’s Professor

Our experience has reinforced one overriding lesson: integrative learning is as much about pedagogy as about curriculum, as much about the culture of learning and collegiality as about specific programs. At Carleton, integrative learning thrives when faculty and staff working collaboratively and with strong administrative support see themselves as collectively responsible for the learning of their students in ways that transcend specific courses, departments, or programs. The distinctive practices of integrative learning are not self-sufficient or easily transferable from one institutional setting to another. They thrive only in a context where collaboration, risk taking, and modeling are actively fostered and rewarded.
