But there's a big downside to this Android growth: Severe fragmentation in the Android market means that startups must tune and debug their apps against a whole range of official Android versions, carrier tweaks, internal smartphone hardware, and external screen dimensions. Pundits have warned about this for years, but now the problem has come home to roost.

Students could use some financial relief. According to an American Enterprise Institute analysis, the cost of textbooks has risen 812% since 1978, compared with a 250% increase in the consumer price index. As a point of reference, medical costs (often described as "spiraling out of control") are up 575% in the same period, according to AEI. The burden is significant enough that 7 in 10 students say they have skipped buying a textbook for a course, trying to make do without it because of the cost. OpenStax adopted a conventional editorial process because that was required to win acceptance in academia, Baraniuk said, but the books are still published in the same modular fashion. That means instructors have the option of creating their own versions, perhaps introducing their own edits or swapping in content from a different source, and assigning that remix. At last count, there were 41 altered versions of OpenStax Physics available in the Connexions repository.

"Peak higher ed means we've reached the maximum size that colleges and universities can support.  What we see now, or saw in 2012, is as big as it gets.  After two generations of growth, American higher education has reached its upper bound."

"While there's no doubt that a college degree increases earning power and broadens opportunities, today's high cost of education means it makes sense to more carefully consider which degree you earn. When it comes to return on investment (ROI), not all degrees are considered equal. This article exposes eight college degrees with poor ROI. "

The dichotomy she describes is a lot like the conceptual move from merely connecting with other educators to collaborating on specific projects. The internet has greatly enhanced educators' capacity to connect with one another, something that only used to happen during professional development or at conferences. But taking that ability to the next level, using it to innovate and produce something new, would mean collaborating beyond districts or even national boundaries.

Red wasn't particularly interested in IPOs or the latest tech fetish, even though she was always exceptionally proud of her students and their accomplishments. She knew that technology was a means to an end - and that the end was people.

"I don't mean to imply any untoward motives by the makers of MOOCs. I'm not arguing that the content or methodologies of most current MOOCs are wrong because they are based on the dominant Western academic approaches. But I do believe it is important to point out that a powerful emerging educational movement strengthens the currently dominant academic culture, perhaps making it more difficult for alternative voices to be heard."

"By "standards … effectiveness … accountability," what Rhee means, of course, is more emphasis on her reform agenda of assessing schools, teachers and students with high-stakes test scores - not at all an agenda uniformly accepted by top-scoring nations. Finnish educator Pasi Sahlberg corrected her on a blog site at the Washington Post, noting that Finland's PISA scores are routinely at or near the top, yet "the Finnish approach to educational policy has stood in direct opposition to the path embraced by the United States.""

""In the world of texting and IMing … the default is to end just by stopping, with no punctuation mark at all," Liberman wrote me. "In that situation, choosing to add a period also adds meaning because the reader(s) need to figure out why you did it. And what they infer, plausibly enough, is something like 'This is final, this is the end of the discussion or at least the end of what I have to contribute to it.'""

"It got me thinking about what types of experiences are best suited for real physical conference events.  Unless we get a chance to interact, ask questions, contribute to conversations, get hands on experience, and do things that require your actual physical presence, then perhaps those other things don't belong in a real physical conference.  I feel a bit cheated when I go to an event (and pay good money to do so) only to feel as though what I experienced could have been just as well communicated virtually through video or some other means.  I feel a bit the same when I go to a real physical conference and find that one of the "keynotes" is being beaming in via satellite on a big screen that we all just sit and watch.  I expect better than that."

"PKM is a set of processes, individually constructed, to help each of us make sense of our world and work more effectively. PKM means taking control of your professional development, and staying connected in the network era, whether you an employee, self-employed, or between jobs."

"The problem is that we get interrupted frequently in the modern workplace. Rituals become habits, and that means we run through the transition cycle every time we stop doing what we're doing. One famous 2007 study found that when people responded to email or instant messaging alerts, it took them 10 to 15 minutes beyond time spent on the interruption to really get back into their original tasks. Those 10 to 15 minutes of headline checking add up."

"Mass higher education, conceptually, is practical, low cost, skills oriented, and mainly concerned with teaching. It caught on because state legislatures and businesses saw it as a means of economic development and a supplier of personnel, and because families saw it as a way of ensuring a place in the middle class for their children. Research universities, on the other hand, grant extraordinary freedom and empowerment to a small, elaborately trained and selected group of people whose mission is to pursue knowledge and understanding without the constraints of immediate practical applicability under which most of the rest of the world has to operate."

Under the supervision of the instructor - there's the rub. I don't mean a kind of aloof, checking-your-Facebook-while-students-work kind of "supervision" but rather the kind of interactive engagement that a coach might have with his or her players while they practice. The coach doesn't do the exercises for the players, but neither does s/he stand off to the side and let them flail around the entire time. There is interaction between the coach and the player, between different players, and between different groups of players. And through that interaction, questions get answered, others get raised - and things get learned, if it's done right.

As technology pioneers, we are inundated with new gadgets, services, apps, messaging, games, and media. We're dosing, vaping, and Lyfting. And that means there are new rules for how to behave. Is it ok to answer an email during dinner? Is Google Glass ever cool? We got some help from Jerry Seinfeld, keen observer of social mores and foibles, on how to cope with modern technology.

""I mean, man, it's like not real life. Not. Real. Life. Why would you be on there when there's this," he gestured, with his chin, to everything around him, the bottleneck of teens, grouping off, chattering. Then he looked over at a small pack of guys dressed a little like him, ambling towards us. "Those are my boys," he said, then offered me his hand to shake. "Hope this helps," he said, adding, at the last moment, "Obviously, like, Facebook is not cool.""

"Connectivism and Connective Knowledge Essays on meaning and learning networks May 19, 2012. Connectivism is the thesis that knowledge is distributed across a network of connections, and therefore that learning consists of the ability to construct and traverse those networks. The bulk of this work is devoted to tracing the implications of this thesis in learning. Yes, this could have been a shorter book - and perhaps one day I'll author a volume without the redundancies, false starts, detours and asides, and other miscellany. Such a volume would be sterile, however, and it feels more true to the actual enquiry to stay true to the original blog posts, essays and presentations that constitute this work."

"'m not a hacker. I don't know how to code. A programmer friend recently joked that I "couldn't tell Boolean from bit shifting" and I don't know what that means. So I was just a little bit intimidated when I sat down to play Hack 'n' Slash, a Legend of Zelda-style adventure that challenges you to solve puzzles by reprogramming the source code of the game itself."

"As is so often the case in Washington, though, the devil is in the details. Our organizations, along with 19 other higher education groups representing nearly every American college and university, have serious concerns about what the TEACH Act would mean for higher education's ability to use technology to advance learning. In short, the legislation would actually prevent us from using new technology to better serve our students, including students with disabilities."

"it falsely assumes that today's students intrinsically understand the nuanced ways in which technologies shape the human experience-how they influence an individual's identity, for example, or how they advance and stymie social progress-as well as the means by which information spreads thanks to phenomena such as algorithms and advertising."
