MOOCs higher education

shared by anonymous on 23 Sep 12 - No Cached
  • Granted, there are no papers to grade, and assignments aren’t free-form, but how does one professor handle so many students? We had four teaching assistants, and my initial plan was that they would spend a lot of time on the discussion forum, answering questions. One night in the early days, I was on the forum at 2 a.m. when I saw a student ask a question, and I was typing my answer when I discovered that another student had typed an answer before I could. It was in the right direction, but not quite there, so I thought I could modify it, but then some other student jumped in with the right answer. It was fascinating to see how quickly students were helping each other. All we had to do was go in and say that it was a good answer. I actually instructed the T.A.’s not to answer so quickly, to let students work for an hour or two, and by and large they find the answers.
  • Most students who register for MOOCs don’t complete the course. Of the 154,763 who registered for “Circuits and Electronics,” fewer than half even got as far as looking at the first problem set, and only 7,157 passed the course. What do you make of that?
  • EdX operates under an honor code, with no way to verify that the student who registered is the one doing the work. Is that likely to change? It’s quite possible employers would be happy with an honor certificate. We’re looking at various methods of proctoring. We have talked about people going to centers to take exams. There are also companies that use the cameras inside a laptop or iPad to watch you and everything else that’s happening in the room while you take an exam, and that may be more scalable.

  • And because we will have all this data on how students actually use our materials, there are opportunities for research on learning. We can watch how many attempts students made before they got an exercise right, and if they got it wrong, what they used to try to find a solution. Did they go to the textbook, go back and watch the video, go to the forum and post a question?

  • If you doubt that we live in a winner-take-all economy and that education is the trump card, consider the vast amounts the affluent spend to teach their offspring.
  • This power spending on the children of the economic elite is usually — and rightly — cited as further evidence of the dangers of rising income inequality.
  • But it may be that the less lavishly educated children lower down the income distribution aren’t the only losers. Being groomed for the winner-take-all economy starting in nursery school turns out to exact a toll on the children at the top, too.
  • ...11 more annotations...
  • There is a lively debate among politicians and professors about whether the economy is becoming more polarized and about the importance of education. Dismissing the value of a college education is one of the more popular clever-sounding contrarian ideas of the moment. And there are still a few die-hards who play down the social significance of rising income inequality.
  • When you translate these abstract arguments into the practical choices we make in our personal lives, however, the intellectual disagreements melt away. We are all spending a lot more money to educate our kids, and the richest have stepped up their spending more than everyone else.
  • spending on children grew over the past four decades and that it became more unequal. “Our findings also show that investment grew more unequal over the study period: parents near the top of the income distribution spent more in real dollars near the end of the 2000s than in the early 1970s, and the gap in spending between rich and poor grew.”
  • But it turns out that the children being primed for that race to the top from preschool onward aren’t in such great shape, either.
  • “What we are finding again and again, in upper-middle-class school districts, is the proportion who are struggling are significantly higher than in normative samples,” she said. “Upper-middle-class kids are an at-risk group.”
  • troubled rich kids. “I was looking for a comparison group for the inner-city kids,” Dr. Luthar told me. “And we happened to find that substance use, depression and anxiety, particularly among the girls, were much higher than among inner-city kids.”
  • “I Can, Therefore I Must: Fragility in the Upper Middle Class,” and it describes a world in which the opportunities, and therefore the demands, for upper-middle-class children are infinite.
  • “It is an endless cycle, starting from kindergarten,” Dr. Luthar said. “The difficulty is that you have these enrichment activities. It is almost as if, if you have the opportunity, you must avail yourself of it. The pressure is enormous.”
  • these parents and children are responding rationally to a hyper-competitive world economy.
  • “When we talk to youngsters now, when they set goals for themselves, they want to match up to at least what their parents have achieved, and that is harder to do.”
  • we live in individualistic democracies whose credo is that anyone can be a winner if she tries. But we are also subject to increasingly fierce winner-take-all forces, which means the winners’ circle is ever smaller, and the value of winning is ever higher.

  • The central paradox of the machines that have made our lives so much brighter, quicker, longer and healthier is that they cannot teach us how to make the best use of them; the information revolution came without an instruction manual.
  • The only way to do justice to our onscreen lives is by summoning exactly the emotional and moral clarity that can’t be found on any screen.
  • MAYBE that’s why more and more people I know, even if they have no religious commitment, seem to be turning to yoga, or meditation, or tai chi; these aren’t New Age fads so much as ways to connect with what could be called the wisdom of old age.

  • Other friends try to go on long walks every Sunday, or to “forget” their cellphones at home. A series of tests in recent years has shown, Mr. Carr points out, that after spending time in quiet rural settings, subjects “exhibit greater attentiveness, stronger memory and generally improved cognition. Their brains become both calmer and sharper.”
  • I noticed that all their talk was of sailing — or riding or bridge: anything that would allow them to get out of radio contact for a few hours.
  • empathy, as well as deep thought, depends (as neuroscientists like Antonio Damasio have found) on neural processes that are “inherently slow.” The very ones our high-speed lives have little time for.
  • I’ve yet to use a cellphone and I’ve never Tweeted or entered Facebook. I try not to go online till my day’s writing is finished, and I moved from Manhattan to rural Japan in part so I could more easily survive for long stretches entirely on foot, and every trip to the movies would be an event.
  • Nothing makes me feel better — calmer, clearer and happier — than being in one place, absorbed in a book, a conversation, a piece of music.
  • For more than 20 years, therefore, I’ve been going several times a year — often for no longer than three days — to a Benedictine hermitage, 40 minutes down the road, as it happens, from the Post Ranch Inn. I don’t attend services when I’m there, and I’ve never meditated, there or anywhere; I just take walks and read and lose myself in the stillness, recalling that it’s only by stepping briefly away from my wife and bosses and friends that I’ll have anything useful to bring to them.

  • Scientists say juggling e-mail, phone calls and other incoming information can change how people think and behave. They say our ability to focus is being undermined by bursts of information. These play to a primitive impulse to respond to immediate opportunities and threats. The stimulation provokes excitement — a dopamine squirt — that researchers say can be addictive. In its absence, people feel bored.
  • “The technology is rewiring our brains,” said Nora Volkow, director of the National Institute of Drug Abuse and one of the world’s leading brain scientists. She and other researchers compare the lure of digital stimulation less to that of drugs and alcohol than to food and sex, which are essential but counterproductive in excess.
  • While many people say multitasking makes them more productive, research shows otherwise. Heavy multitaskers actually have more trouble focusing and shutting out irrelevant information, scientists say, and they experience more stress.

  • Take the notion that children have specific learning styles, that some are “visual learners” and others are auditory; some are “left-brain” students, others “right-brain.” In a recent review of the relevant research, published in the journal Psychological Science in the Public Interest, a team of psychologists found almost zero support for such ideas.

  • What we recall becomes more recallable in the future. In a sense you are practicing what you are going to need to do later.”

      In the narrative recall version of the test the subjects were made to reread the article numerous times. In the concept mapping version they were directed to read the article once. The different outcomes could just be related to the power of re-reading something. Also, narrative recall isn't what most tests look like. That label is clearly a misnomer.

  • Taking a test is not just a passive mechanism for assessing how much people know, according to new research. It actually helps people learn, and it works better than a number of other studying techniques.
  • “I think that learning is all about retrieving, all about reconstructing our knowledge,” said the lead author, Jeffrey Karpicke, an assistant professor of psychology at Purdue University. “I think that we’re tapping into something fundamental about how the mind works when we talk about retrieval.”

    The iPad (or iPod touch or iPhone) with its apps opens many new opportunities for learning. At the same time, it offers a slightly different wrapper for older learning opportunities. Both can be worthwhile, but it would be a shame if teachers missed the former for the latter. And, if past experience and research is any indication, educators are much more likely to co-opt the new technology to accomplish the status quo. This activity is designed to help teachers think through both opportunities and to categorize those apps that lend themselves to either or both. Teachers will start by exploring a variety of apps, some that lend themselves to learning content such as math facts or spelling words and others that can be used in open ended content creation such as storytelling or photography. Then, teachers will examine a set of lessons that use these apps. Finally, teachers will use a "taxonomy" such as Bloom's Taxonomy, SAMR, LoTi, ETaP, Prensky, etc. and attempt to classify/categorize where the apps fall. Most likely teachers will need to contextualize the app to a particular use/activity. Ideally, teachers will realize that in most cases it is not the app itself, but the use that detrmines where it falls and that the apps belong in multiple places.

Font Size May Not Aid Learning, but Its Style Can, Researchers Find - NYTimes.com - 110 views

education undergraduate Learning font

shared by D. S. Koelling on 19 Apr 11 - No Cached
  • Is it easier to remember a new fact if it appears in normal type, like this, or in big, bold letters, like this?
  • Font size has no effect on memory, even though most people assume that bigger is better. But font style does.
  • New research finds that people retain significantly more material — whether science, history or language — when they study it in a font that is not only unfamiliar but also hard to read.
  • ...6 more annotations...
  • “So much of the learning that we do now is unsupervised, on our own,” said Robert A. Bjork, a psychologist at the University of California, Los Angeles, “that it’s crucial to be able to monitor that learning accurately; that is, to know how well we know what we know, so that we avoid fooling ourselves.”
  • “Studying something in the presence of an answer, whether it’s conscious or not, influences how you interpret the question,” Dr. Bjork said. “You don’t appreciate all of the other things that would have come to mind if the answer weren’t there. “Let’s say you’re studying capitals and you see that Australia’s is Canberra. O.K., that seems easy enough. But when the exam question appears, you think: ‘Uh oh, was it Sydney? Melbourne? Adelaide?’ ” That’s why some experts are leery of students’ increasing use of online sites like Cramster, Course Hero, Koofers and others that offer summaries, step-by-step problem solving and copies of previous exams. The extra help may provide a valuable supplement to a difficult or crowded course, but it could also leave students with a false sense of mastery. Even course outlines provided by a teacher, a textbook or other outside source can create a false sense of security, some research suggests. In one experiment, researchers found that participants studying a difficult chapter on the industrial uses of microbes remembered more when they were given a poor outline — which they had to rework to match the material — than a more accurate one.
  • a cognitive quality known as fluency, a measure of how easy a piece of information is to process.
  • On real tests, font size made no difference and practice paid off, the study found.
  • And so it goes, researchers say, with most study sessions: difficulty builds mental muscle, while ease often builds only confidence.
  • To test the approach in the classroom, the researchers conducted a large experiment involving 222 students at a public school in Chesterland, Ohio. One group had all its supplementary study materials, in English, history and science courses, reset in an unusual font, like Monotype Corsiva. The others studied as before. After the lessons were completed, the researchers evaluated the classes’ relevant tests and found that those students who’d been squinting at the stranger typefaces did significantly better than the others in all the classes — particularly in physics. “The reason that the unusual fonts are effective is that it causes us to think more deeply about the material,” a co-author of the study, Daniel M. Oppenheimer, a psychologist at Princeton, wrote in an e-mail. “But we are capable of thinking deeply without being subjected to unusual fonts. Think of it this way, you can’t skim material in a hard to read font, so putting text in a hard-to-read font will force you to read more carefully.” Then again, so will raw effort, he and other researchers said. Concentrating harder. Making outlines from scratch. Working through problem sets without glancing at the answers. And studying with classmates who test one another.
