Oculus Rift VR Sets Begin Shipping

Online learning update by Ray Schroeder - Wed, 2016-04-13 02:02

By Dian Schaffhauser, THE Journal

Rift has arrived. Oculus announced in a blog that it had begun shipping its virtual reality (VR) headset first to those who invested in its idea through Kickstarter. Next, pre-ordered Rifts will ship out, starting “mid-week.” Everybody else will have to hold on until July. That’s when the $599 units are expected to be available through the Oculus shop online. Or customers can choose a bundle that includes the headset and a gaming-caliber PC (most sans monitor) from Microsoft and Best Buy. A few hustlers have also listed their Rifts for sale through Amazon for prices ranging from $1,200 up.

Change We Must: Deciding the Future of Higher Education (Release date today)

Online learning update by Ray Schroeder - Tue, 2016-04-12 02:12

by George Otte, Matthew Goldstein… Ray Schroeder, Vickie Cook, et al.

President of APLU, Peter McPherson, writes: “This book about change and reform is written by people who have spent their lives in higher education. Their concerns and proposals come from their deep commitment to our purposes and should be taken seriously by other serious people.” With chapters by the editors and Schroeder/Cook; Cathy Davidson; Candace Thille; James Hilton; Jonathan Cole; and Michael Zavelle, this book looks closely at the forces at play in higher education and the points to paths of positive change.  William Kirwan, Chancellor Emeritus of the University System of Maryland writes “In eight insightful essays and with uncommon wisdom, this anthology addresses major issues confounding American higher education leaders today. From university governance in a time of dramatic change to the challenges and uncertainties of technology-based “disruptions,” the authors provide a thoughtful and hopeful roadmap to the future. It is a ‘must read’ for all who care about the well being of our nation’s colleges and universities.”  [disclosure note: as indicated, I am a co-author].

Online learning options meet students’ needs

Online learning update by Ray Schroeder - Tue, 2016-04-12 02:05

By Jennifer Kimrey, Chron

Students with difficult schedules or other circumstances have the option to pursue education online. Online classes and degrees provide the same quality instruction as in-person programs. “Online classes benefit students who work full time and cannot go to a campus during work hours, parents with small children at home or those who are a caregiver for another family member, have problems getting to a campus, just don’t want to go to a campus, like the flexibility of setting their own hours or may be shy in a physical classroom and wish to have their voice ‘heard’ online,” said Lorah Gough, director of Houston Community College Online. Those enrolled in online courses and degree programs often will find that goals and outcomes, class format and semester schedules are nearly identical to physical classes.

Why traditional institutions must assess or be assessed

Online learning update by Ray Schroeder - Tue, 2016-04-12 02:03

BY MERIS STANSBURY, eCampus News

It’s a debate that’s spreading across the country: should colleges and universities have standardized assessments to measure student performance metrics? The Obama administration says yes, while most campus faculty and students say no. What should be done? According to Fredrik deBoer, a scholar and lecturer at Purdue University, it’s only a matter of time before institutions are forced to assess student performance in a standardized way, so they might as well get ahead of the curve in order to retain control of those assessments. “Every conversation that’s taking place about higher education today ultimately ends up around assessments,” said Kevin Carey, New America’s education policy program director. “Whenever there’s talk about price, value, outcomes, accreditation, innovation implementation, et cetera, it always comes down to proving student learning somehow. And weirdly enough, there’s very little solid research on student learning at the individual student- and department-level.”

Massive open online courses are getting bigger as Hong Kong universities embrace the changes

Online learning update by Ray Schroeder - Tue, 2016-04-12 02:02

by SCMP

“Worldwide, OERs and MOOCs are being offered free of charge, as a philanthropic and altruistic movement, and as a testing ground for offering effective learning online,” says Dr Yuen Kin-sun, director of the Educational Technology and Publishing Unit at The Open University of Hong Kong. “We’re still at an early, rather anarchic stage, where many courses carry no or only a nominal cost, and are frequently delivered by leaders in their field.” According to MOOC aggregator Class Central, there are now about 4,200 MOOCs offered by more than 500 universities around the world, with the number of students who signed up for at least one course hitting more than 35 million in 2015, roughly twice as many as in 2014.

Building the Goodwill of Networks

OLDaily by Stephen Downes - Mon, 2016-04-11 23:52


Simon Terry, Apr 11, 2016

I'm not sure exactly what to make of this post. Sure, the author points to a series of problems that plague network behaviour, from the problem of noise, to requests for information that can be found in the manual, to unclear requests, to people making requests without providing responses of their own. But it's framed like the tragedy of the commons, posed as a problem of free riders. "Great networks build up goodwill among the members which facilitates collaboration through trust, shared connection and a sense of reciprocal benefits. Free riders are members of those networks who don’ t contribute to the general goodwill," writes Simon Terry. But this is just nonsense. Networks aren't some sort of quid pro quo marketplace. The ability of people to contribute is asymmetrical. 'Goodwill' isn't some sort of pseudo-network currency. And it's silly to think of a network simply as a question-answer sort of system.

Linking online identities and content in connectivist MOOCs across multiple social media platforms

OLDaily by Stephen Downes - Mon, 2016-04-11 23:52


Anatoliy Gruzd, Ryerson University | Social Media Lab, Apr 11, 2016

I love the colourful diagrapm that accompanies this post. And the content is pretty good too. The authors "focus on how to link multiple online identities of learners and their contributions across several social media platforms in order to study their learning behaviours in open online environments." In the paper (6 page PDF) the authors found that less identity resolution that expected was needed because the participants mainly used Twitter, even when they were taking different courses. This might be one of those results that needs more study, because while the educational community uses Twitter a lot, the network is less pervasive in other communities.

Does neuron ‘feedback’ let the brain trick us?

OLDaily by Stephen Downes - Mon, 2016-04-11 23:52


Jocelyn Duffy, Futurity, Apr 11, 2016

"Seeing something that isn’ t really there could be your brain reacting to feedback between neurons in different parts of the visual system, according to new research.... it signifies that studying neuronal feedback is important to our understanding of how the brain works to process stimuli." This is interesting, too, because it shows that the interaction between neurons in the visual cortex isn't all one way - it's doesn't proceed straight from input layers to output, but sometimes moves back and forward between layers. Cool!

Great Leaders Embrace Office Politics

OLDaily by Stephen Downes - Mon, 2016-04-11 20:52


Michael Chang Wenderoth, Harvard Business Review, Apr 11, 2016

So says the Hrvard Business Review: "There is strong evidence that our work ratings, bonuses, and promotions are weakly correlated to actual performance — in fact, performance may even matter less to our success than our political skills and how we are perceived by those who make the decisions." I'm not sure that this is what creates 'great' leaders, but it does characterize the nature of those who survive.

Deep learning will be huge — and here’s who will dominate it

Online learning update by Ray Schroeder - Mon, 2016-04-11 02:06

by AMIT KARP,Venture Beat

Artificial intelligence* is developing much faster than we thought. Just last month, Google’s DeepMind AI beat Lee Sedol, a legendary Go player, at his own game in a defining moment for the industry. What enabled this win is a relatively new AI technique called deep learning, which is transforming AI. Until deep learning was introduced, even the best AI systems were always highly tuned for specific problems and required many rules to operate successfully. But deep learning has changed that, causing many researchers to abandon classical AI approaches. Deep learning relies on simulating large, multilayered webs of virtual neurons, which enable a computer to learn to recognize abstract patterns (somewhat similar to the way a human brain operates). It can be used to solve any general-purpose pattern-recognition problem, which means that any activity that has access to large amounts of data can find it useful.

This British website is training med students to become doctors in Syria

Online learning update by Ray Schroeder - Mon, 2016-04-11 02:04

BY OSCAR LOPEZ, Mashable

Modeled on the Oxbridge tutorial system, SyriaScholar gives small groups of students direct one-on-one interaction with tutors. The brothers used available, open-source software to build the website, which includes a platform for video-conferencing, allowing them to run the two-way tutorials online as well as upload powerpoint presentations that the students can follow during the tutorials. The lessons are also recorded. Currently, they are working with students from Al-Andalus University for Medical Sciences in the city of Qadmus, as well as Tishreen University in Latakia, and they’re hoping to expand the program to Damascus University. The tutorial sessions, given in English, provide students like Ahmad with a level of practical, personalised teaching that their own universities simply could not provide right now. “The information from lectures we have had from SyriaScholar, like how to read an [electrocardiogram] or chest X-rays, gave us knowledge that was missed out by our lecturers here,” he said.

#Infographic: The Urban Higher Education Ecosystem Solution

Online learning update by Ray Schroeder - Mon, 2016-04-11 02:02

by the Kresge Foundation

Earning a college degree or credential, now more than ever, is essential to achieving a stable, middle-class life and upward mobility. But just 1 in 10 students from low-income families will earn a bachelor’s degree by age 25, compared with more than 7 in 10 people from higher income families. With so many low-income students attending postsecondary institutions in urban areas, the Education Program at The Kresge Foundation has focused on a solution – improving the urban higher education ecosystem. This ecosystem includes colleges and universities, nonprofit organizations, employers, K-12 school districts and government agencies, as well as systems such as housing, transportation, food, financial aid, and childcare.

Explore the Do’s, Don’t’s of Interacting With Online Course Instructors

Online learning update by Ray Schroeder - Sun, 2016-04-10 02:04

By Bradley Fuster, US News

Everyone remembers the students in grade school who sat in the front, raised their hands to give every answer, endlessly complimented the teacher, grabbed attention at every opportunity and frustrated the entire class. Socially intelligent students eventually learn how to be a star pupil without resorting to such disruptive behavior. The ideal balance of admiration for the teacher and need to impress is tricky to establish in a live learning environment. In an online class, without the ability to process nonverbal cues and a lag time in most dialogue, establishing healthy patterns of communication with professors is even more complex. Below are four common do’s and don’t’s for online learners to establish and maintain a healthy interpersonal relationship with their professors.

Putting Her In Her Place: How Men Engage In Targeted Harassment Online

Online learning update by Ray Schroeder - Sun, 2016-04-10 02:03

by Casey Bennett, Libertarian Republic

Of course, when women talk about targeted online harassment, we aren’t denying it happens to men. No, when women talk about this type of harassment, we’re talking about the 26% of young women aged 18-24 who have been stalked online, compared to 7% of young men in the same age group. We’re talking about the 25% of women who have experienced sexual harassment, compared to 13% of men, and, while it’s close, the 18% who have experienced sustained harassment, compared to 16% of men. We’re talking about gender-specific harassment, to which women are subjected more often. Several solutions have been floated as a means of combating targeted online harassment, of course, from the creation of women-only social media websites and additional reporting measures to banning IP addresses as a means of preventing specific users from registering new accounts, but these “solutions” are merely band-aids. They do nothing to address the underlying problem that some men feel it’s their duty to put a woman in her place.

Online learning equals virtual success

by William J. Lowe, Chicago Tribune

Earlier this year, the Indiana Commission for Higher Education released an alarming figure. More than 750,000 Indiana residents, or about 22 percent of the state’s working-age adults, have attended some college, but, due to various circumstances, quit before completing their degrees. The value of a degree has never been greater or more attainable, thanks to advances in technology. There is no better time than now to support your family, and your dreams, by investing in a college degree. One way to do so is through online learning, which provides all students the convenience that fits their busy, highly complex lives.

A Nursing Intelligence System to Support Secondary Use of Nursing Routine Data.

Appl Clin Inform. 2015;6(2):418-28

Authors: Hackl WO, Rauchegger F, Ammenwerth E

Abstract
BACKGROUND: Nursing care is facing exponential growth of information from nursing documentation. This amount of electronically available data collected routinely opens up new opportunities for secondary use.
OBJECTIVES: To present a case study of a nursing intelligence system for reusing routinely collected nursing documentation data for multiple purposes, including quality management of nursing care.
METHODS: The SPIRIT framework for systematically planning the reuse of clinical routine data was leveraged to design a nursing intelligence system which then was implemented using open source tools in a large university hospital group following the spiral model of software engineering.
RESULTS: The nursing intelligence system is in routine use now and updated regularly, and includes over 40 million data sets. It allows the outcome and quality analysis of data related to the nursing process.
CONCLUSIONS: Following a systematic approach for planning and designing a solution for reusing routine care data appeared to be successful. The resulting nursing intelligence system is useful in practice now, but remains malleable for future changes.
