  • However, e-readers must be significantly improved to have the same value in a teaching environment as traditional paper texts, participants said.
  • but they also said the ability to highlight directly on traditional text, to take notes and flip pages for ease in navigation suffers in the e-reader.
  • With hopes of assisting industry with the refinement of e-readers, and providing useful information to other academic institutions considering the devices, information and data from the one-time pilot have been compiled on an Office of Information Technology (OIT) website.
  • ...5 more annotations...
  • About 65 percent of the participants in the pilot said they would not buy another e-reader now if theirs was broken. Almost all the participants said they were interested in following the technology to its next stages, because they think a device that works well in academia would be worth having.
  • "I found the device difficult to use and not conducive to academic purposes," he said, and added, "But I can see how it can be used for pleasure reading."
  • What they liked best about the devices was: the battery life, the wireless connection and the portability of the e-reader; the fact that all the course reading was on one device; the ability to search for content; and the legibility of the screen, including the fact it could be read in full sunlight. The top five suggestions students had for improving e-readers were: improving the ability to highlight and annotate PDF files; improving the annotation tools; providing a folder structure to keep similar readings together; improving the highlighting function; and improving the navigation within and between documents on the reader (including having more than one document open at the same time for comparison).
  • "The Kindle would be better for an academic setting if the PDF format worked more effectively,"
  • "There would be a greater benefit realized if the devices could develop a better way to deliver the ubiquitous PDF document, which is used by many journals and libraries to deliver documents, and is the common format in which dissertations and theses are published and read by faculty," Temos said. "Some students said they spent a considerable amount of time printing PDF documents during the semester, and hardly ever referred back to them once the semester was over. I don't expect that is unusual."

  • But when the results from the first major international math test came out in 1967, the effort did not seem to have made much of a difference. Japan took first place out of 12 countries, while the United States finished near the bottom.
  • By the early 1970s, American students were ranking last among industrialized countries in seven of 19 tests of academic achievement and never made it to first or even second place in any of them. A decade later, "A Nation at Risk," the landmark 1983 report by the National Commission on Excellence in Education, cited these and other academic failings to buttress its stark claim that "if an unfriendly foreign power had attempted to impose on America the mediocre educational performance that exists today, we might well have viewed it as an act of war."

  • J. Michael Shaughnessy, president of the National Council of Teachers of Mathematics, argues that the latest PISA test "underscores the need for integrating reasoning and sense making in our teaching of mathematics." Randi Weingarten, head of the American Federation of Teachers, claims that the same results "tell us … that if you don't make smart investments in teachers, respect them, or involve them in decision-making, as the top-performing countries do, students pay a price."

      People use crises to advance their own agendas...
  • But don't expect any of them to bring the country back to its educational golden age -- there wasn't one.
  • According to the most recent statistics, the U.S. share of foreign students fell from 24 percent in 2000 to just below 19 percent in 2008. Meanwhile, countries like Australia, Canada, and Japan saw increased market shares from their 2000 levels, though they are still far below the American numbers.
  • And even with its declining share, the United States still commands 9 percentage points more of the market than its nearest competitor, Britain.
  • A 2008 Rand Corp. report found that nearly two-thirds of the most highly cited articles in science and technology come from the United States, and seven in 10 Nobel Prize winners are employed by American universities. And the United States spends about 2.9 percent of its GDP on postsecondary education, about twice the percentage spent by China, the European Union, and Japan in 2006.
  • But over the long term, exactly where countries sit in the university hierarchy will be less and less relevant, as Americans' understanding of who is "us" and who is "them" gradually changes. Already, a historically unprecedented level of student and faculty mobility has become a defining characteristic of global higher education. Cross-border scientific collaboration, as measured by the volume of publications by co-authors from different countries, has more than doubled in two decades.

    I disliked this video. Is my classroom extraordinary? The rest of the classrooms in the U.S. have unmoving, silent children stuck in desks all day? The students don't talk to each other? They don't collaborate to solve problems? They don't read? They don't write in order to analyze and express opinions? They don't use math manipulatives, do science experiments, build, draw, and do projects? They don't laugh together, digress, and then get back on track? Because that's what we do. It doesn't strike me as a response to the Industrial Revolution as much as a response to students' curiosity and to their future needs. "If we get it right, kids won't even know they're learning something." So, we're doing it wrong if the kids are actually aware that they're learning? Better they should be metaphorically anesthetized by the computer experience? We don't want them inoculated against feeling the discomfort of struggle. Every respected neuroscientist on the planet says struggle is necessary to wire neurons together, which is the physical manifestation of learning. The simulation of the village looks very cool. I love computers. But if all their learning about ancient Rome is based on this simulation, where are the primary sources? Will students encounter any? Or is their experience of the village based on someone else's interpretation of primary sources? If so, then someone else gets to decide what is important to include in the Roman village. They get to choose and interpret the facts that are used to create the virtual ancient Roman experience. That goes against best practice teaching of the social sciences.

  • Edge is different from the Algonquin Roundtable or Bloomsbury Group, but it offers the same quality of intellectual adventure. Closer resemblances are the early seventeenth-century Invisible College, a precursor to the Royal Society. Its members consisted of scientists such as Robert Boyle, John Wallis, and Robert Hooke. The Society's common theme was to acquire knowledge through experimental investigation. Another inspiration is The Lunar Society of Birmingham, an informal club of the leading cultural figures of the new industrial age — James Watt, Erasmus Darwin, Josiah Wedgewood, Joseph Priestly, and Benjamin Franklin. The online salon at Edge.org is a living document of millions of words charting the Edge conversation over the past fifteen years wherever it has gone. It is available, gratis, to the general public.
  • Edge.org offers "open-minded, free ranging, intellectually playful ... an unadorned pleasure in curiosity, a collective expression of wonder at the living and inanimate world ... an ongoing and thrilling colloquium." 
  • encourages people who can take the materials of the culture in the arts, literature, and science and put them together in their own way. We live in a mass-produced culture where many people, even many established cultural arbiters limit themselves to secondhand ideas, thoughts, and opinions. Edge.org consists of individuals who create their own reality and do not accept an ersatz, appropriated reality. The Edge community consists of peole who are out there doing it rather than talking about and analyzing the people who are doing it.

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.

  • The study found that in 64 percent of children with ADHD, the symptoms were caused by food. "It's a hypersensitivity reaction to food," Pessler said.
  • But Pessler's study indicates that up to two-thirds -- or 2 of the 3 million children currently medicated for ADHD -- may not need medication at all. "With all children, we should start with diet research," Pessler said.
  • After three years on Ritalin, children were about an inch shorter and 4.4 pounds lighter than their peers, according to a major study published in the Journal of the American Academy of Child and Adolescent Psychiatry in 2007.
  • ...2 more annotations...
  • There are a multitude of credible scientific studies to indicate that diet plays a large role in the development of ADHD.
  • there are two factors at work in this study: One being the allergic reaction to the actual foods themselves and the second being a possible reaction to food additives, or combinations of food additives, found in industrial foods. Both certainly could be at play in the results of this study, although the discussion of Dr. Pessler's study thus far hasn't addressed the latter issue.

curriculum trends future education

shared by Gerald Carey on 25 Apr 11 - No Cached
  • Given the growing momentum of these trends, what does it mean for students, teachers, schools, and the education community at large? Collaborating and customizing. Educators are learning to work together, with their students, and with other experts in creating content, and are able to tailor it to exactly what they need. Critical thinking. Students are learning how to effectively find content and to discern reliable sources. Democratizing education. With Internet access becoming more ubiquitous, the children of the poorest people are able to get access to the same quality education as the wealthiest. Changing the textbook industry. Textbook publishers are finding ways to make themselves relevant to their digital audience. Emphasizing skills over facts. Curriculum incorporates skill-building.
  • Gerald Carey on 25 Apr 11
     
    Sorry forgot the three trends (the above are consequences of these trends) 1. Digital delivery "No longer shackled to books as their only source of content, educators and students are going online to find reliable, valuable, and up-to-the-minute information" 2. Interest driven curriculum "Though students typically have to wait until their third year of college to choose what they learn, the idea of K-12 education being tailored to students' own interests is becoming more commonplace" 3. Skills 2.0 " Instead of learning from others who have the credentials to 'teach' in this new networked world, we learn with others whom we seek (and who seek us) on our own and with whom we often share nothing more than a passion for knowing"
