Looking past massive pool of registrants, edX probes tiny subgroup of MOOC students who actually stuck around to the end of its pilot course.

The Massachusetts Institute of Technology ended 2011 with a grand announcement: It would broadcast massive, open online courses - equal in rigor to its on-campus offerings - to tens of thousands of non-enrolled, non-paying learners around the world. Eventually, the university would offer these students a pathway to some sort of credential.

Designing and building things for the United States military is a notoriously slow-moving and costly endeavor. The time from idea to manufacturing for a new armored personnel carrier or a tank is typically 10 to 20 years. The Defense Advanced Research Projects Agency wants to change that, and drastically so.It seeks to cut the design-to-production cycle to two to four years. So how are they going to do it? Crowdsourcing and prize contests are crucial ingredients in the speed-up recipe. The crowdsourcing effort will rely on a software initiative, called Vehicleforge.mil, which will be a Web portal for gathering, sharing and testing ideas.

The recent bankruptcy declaration by Kodak, one of the nation's most trusted brands for consumers, which once held a market share in excess of 90 percent, is stunning. Kodak mistook America's century-long love affair with its products as a sign of market permanency, missing the fact that camera phones, flip cameras and online sharing would erode its brand and render it irrelevant.American higher education should take heed because it is facing a similar challenge, with implications far more important than the loss of a major corporation

Every other Monday, right before class ends, Muhammad Zaman, a Boston University biomedical engineering professor, hands out a one-page form asking students to anonymously rate him and the course on a scale of one to five.

"Has he improved his teaching since the last evaluation? In particular, has he incorporated your suggestions?" "How can the material be altered to improve your understanding of the material?" "Anything else you would like to convey to the professor?" College learning assessments and professorial ratings come in many forms, with new ones popping up all the time. Ratemyprofessors.com has been going strong for years, and almost everywhere, colleges ask students to fill out end-of-term evaluations - and increasingly, midterm evaluations as well. Many professors with large lecture classes swear by clickers that help them keep tabs on how well their students are following the material. Some online courses include dashboards that let professors see which students are stuck, and where. And thousands of professors use some variation of K. Patricia Cross's "One-Minute Paper" approach, in which, at the end of each class, students write down the most important thing they learned that day - and the biggest question left unanswered. But even in an era when teacher evaluations and learning assessments are a hot topic in education, Dr. Zaman stands out in his constant re-engineering of his teaching: He graphs the results the day he collects them (an upward trend is visible), sends out an e-mail telling the class abo

What drives many district and state technology leaders bonkers is being asked time and again by their school boards, superintendents, parents, and media: What does the research say about whether we should invest in iPads, tablets, and 1:1 laptops? What they really want to know is: does the new technology work?

If you are a technology advocate, that is, someone who believes in his or her heart-of-hearts that new devices, new procedures, and new ways of using these devices will deliver better forms of teaching and learning, past and contemporary research findings are, to put it in a word-disappointing. How come?

In the last years of the nineteenth century, Charles Dow created an index of 12 leading industrial companies. Almost none of them exist today. While General Electric remains an industrial giant, the U.S. Leather Company, American Cotton Oil, and others have long since disappeared into bankruptcy or consolidation.

Completing assignments and sitting through exams can be stressful. But when it comes to being graded the waiting is often the hardest part. This is perhaps most true at the end of a semester, as students wait for their instructors to reduce months of work into a series of letter grades that will stay on the books forever. But at Austin Peay State University, students do not have to wait for the end of a semester to learn their grade averages. Thanks to a new technology, pioneered by the university's provost, they do not even have to wait for the semester to start. Tristan Denley, the provost, has built software, called Degree Compass, that analyzes an individual student's academic record, along with the past grades of hundreds of Austin Peay State students in various courses, and predicts how well a particular student is likely to do in a particular course long before the first day of class. (That includes first-year students; the software draws on their high school transcripts and standardized test scores.)

A venture capitalist panel at SXSW interactive conference has discussed the future of education technology. The panelists, Mitch Kapor, Phillip Bronner and Rob Hutter claimed to have a broad vision of investing that looked for technology to be more than just successful but that also created social value.

Michael Wesch has been on the lecture circuit for years touting new models of active teaching with technology. The associate professor of cultural anthropology at Kansas State University has given TED talks. Wired magazine gave him a Rave Award. The Carnegie Foundation for the Advancement of Teaching once named him a national professor of the year.

But this course, Building a Search Engine, is taught by two prominent computer scientists, Sebastian Thrun, a Stanford research professor and Google fellow, and David Evans, a professor on leave from the University of Virginia. The big names have been a big draw. Since Udacity, the for-profit startup running the course, opened registration on Jan.

What's so special about a diploma? With the advent of Massive Open Online Courses and other online programs offering informal credentials, the race is on for alternative forms of certification that would be widely accepted by employers. "Who needs a university anymore?"

As the private sector works faster and more boldly to churn out next-generation technology and embrace cutting-edge practices, the U.S. Department of Education and its partner federal agencies are ramping up their efforts to bring more spark and innovation into elementary and secondary schools.

Salman Khan, a graduate of the Massachusetts Institute of Technology and the Harvard Business School, was working as a hedge fund manager when he began posting videos on YouTube six years ago to tutor young family members in math. That led to the 2008 creation of the Khan Academy, a nonprofit organization that has built a free, online collection of thousands of digital lessons (nearly 3,000 of them created by Mr. Khan himself) and exercises in subjects ranging from algebra to microeconomics. Education Week Staff Writer Lesli A. Maxwell recently interviewed Mr. Kahn about the evolution of the academy and its potential for changing K-12 education.

Attorneys general from more than 20 states have joined forces to investigate for-profit colleges that too often saddle students with crippling debt while furnishing them valueless degrees. The investigations have just begun. But it is already clear from testimony before a Senate committee that Congress must do more to rein in the schools and protect students.

Kids don't put Harvard stickers on their rear windshields, parents do. But for how long? These schools have much to recommend them: impressive students, organic dining halls, presidential alumni. To maintain their reputations, however, elite colleges have long relied on limiting access-Harvard's class of 2015 is about 1,700 students, Yale's is 1,300-and that may be coming to an end. Revolutionaries outside the ivy walls are hammering their way not onto campus but straight into class.

Last fall, a couple of hundred Stanford students registered for Sebastian Thrun's class on artificial intelligence. He offered the course free online, too, through his new company Udacity, and 160,000 students signed up. For the written assignments and exams, both groups got identical questions-and 210 students got a perfect overall score. They all came from the online group. So if you bluffed your way into the Ivy League with plumped-up credentials or an essay edited by somebody else, it's time to start breaking a sweat. "I like to compare it to film," Mr. Thrun told me at a coffee shop between Stanford and Mountain View, Calif., where his day job is running Google X, the company's experimental lab. "Before film there was theater-small casting companies reaching 300 people at a time. Then celluloid was invented, and you could record something and replicate it. A good movie wouldn't reach 300 but 3,000, and soon 300,000 and soon three million. That changed the economics." It is education's time to change now. At the high-school level, interactive study sites are increasingly ingenious: Look at Piazza, Blackboard and Quizlet, founded by a 17-year-old. TED-Ed just launched a channel on You Tube, with three- to 10-minute lessons for kids. YouTube's EDU Portal has been viewed 22 billion times. Khan Academy, a favorite of Bill Gates

College is expensive. Ask any family with post-secondary students and they will tell you just how outrageous are the costs of college education today. And yes, gas, food, and life in general are expensive. But college costs have risen much faster than average inflation for decades so this isn't a [...]

Would you sacrifice part of the proverbial best four years of your life to cut costs? Paying eight semesters' worth of tuition, room and board, textbooks and other fees can add up to tens of thousands of dollars, and that's if you finish college in four years.

WASHINGTON -- The college "completion agenda" is running behind schedule, at least in substantially boosting the national proportion of degree-holders. But from a policy and public-relations perspective, the foundation-led campaign has been a home run. On Monday the Lumina Foundation released its third annual report tracking progress toward the foundation's goal for 60 percent of Americans to obtain a "high quality" degree or credential by 2025. The report found that 38.3 percent of working-age adults held at least a two-year degree in 2010, which is up from 37.9 in 2008. At that pace, less than 47 percent of Americans will hold a degree by 2025, according to the report, which will leave the workforce short by 23 million needed degree-holders. "We are nowhere near at the pace we need to be," said Jamie Merisotis, Lumina's president and CEO.
