  • Photo Tampering Throughout History Photography lost its innocence many years ago. In as early as the 1860s, photographs were already being manipulated, only a few decades after Niepce created the first photograph in 1814. With the advent of high-resolution digital cameras, powerful personal computers and sophisticated photo-editing software, the manipulation of digital images is becoming more common. Here, I have collected some examples of tampering throughout history. To help contend with the implications of this tampering, we have developed a series of tools for detecting traces of tampering in digital images (contact me at Ma'at Consulting for more information about our services). circa 1860: This nearly iconic portrait of U.S. President Abraham Lincoln is a composite of Lincoln's head and the Southern politician John Calhoun's body. Putting the date of this image into context, note that the first permanent photographic image was created in 1826 and the Eastman Dry Plate Company (later to become Eastman Kodak) was created in 1881. circa 1865: In this photo by famed photographer Mathew Brady, General Sherman is seen posing with his Generals. General Francis P. Blair (far right) was added to the original photograph.

      This explains, in real terms, why I've had so much struggle with online reading! Very interesting article.
  • Because of these preferences—and because getting away from multipurpose screens improves concentration—people consistently say that when they really want to dive into a text, they read it on paper

      This is backed up by a recent article: Faris, Michael J., and Stuart A. Selber. "E-Book Issues In Composition: A Partial Assessment And Perspective For Teachers." Composition Forum 24.(2011): ERIC. Web. 31 Mar. 2013.

  • When reading a paper book, one can feel the paper and ink and smooth or fold a page with one's fingers; the pages make a distinctive sound when turned; and underlining or highlighting a sentence with ink permanently alters the paper's chemistry.
  • discernible size, shape and weight.
  • Although many old and recent studies conclude that people understand what they read on paper more thoroughly than what they read on screens, the differences are often small. Some experiments, however, suggest that researchers should look not just at immediate reading comprehension, but also at long-term memory.
  • When taking the quiz, volunteers who had read study material on a monitor relied much more on remembering than on knowing, whereas students who read on paper depended equally on remembering and knowing.
  • E-ink is easy on the eyes because it reflects ambient light just like a paper book, but computer screens, smartphones and tablets like the iPad shine light directly into people's faces.
  • the American Optometric Association officially recognizes computer vision syndrome.
  • People who took the test on a computer scored lower and reported higher levels of stress and tiredness than people who completed it on paper.
  • Although people in both groups performed equally well on the READ test, those who had to scroll through the continuous text did not do as well on the attention and working-memory tests.
  • Subconsciously, many people may think of reading on a computer or tablet as a less serious affair than reading on paper. Based on a detailed 2005 survey of 113 people in northern California, Ziming Liu of San Jose State University concluded that people reading on screens take a lot of shortcuts—they spend more time browsing, scanning and hunting for keywords compared with people reading on paper, and are more likely to read a document once, and only once.
  • When reading on screens, people seem less inclined to engage in what psychologists call metacognitive learning regulation—strategies such as setting specific goals, rereading difficult sections and checking how much one has understood along the way
  • Perhaps she and her peers will grow up without the subtle bias against screens that seems to lurk in the minds of older generations.

  • When it comes to intensively reading long pieces of plain text, paper and ink may still have the advantage. But text is not the only way to read.

  • Standardized tests have much in common with French fries. Both of them differ in composition as well as quality. French fries are available in numerous incarnations, including straight, curly, skins-on, skins-off, and, in recent years, with sweet potatoes. Regarding quality, of course, the taste of French fries can range substantially – from sublime to soggy. It’s really the same with standardized tests.
  • Take the No Child Left Behind Act, for instance, a federal accountability law requiring scads of standardized tests to be used in evaluating schools. Do you know that almost all of the standardized tests now being employed to judge school quality are unable to distinguish between well taught and badly taught students?

  • all schools – kindergarten through college – should employ exit exams allowing us to determine what students have actually learned. We owe it to our students to make sure that they’ve been properly taught.
  • Then there are the questions of what to do with the results. I have actually sat through an extended discussion of how we could use regression analysis to parse out the contribution different teachers made to a group of students’ performance on a set of standardized tests. The answer was, yes it was possible, and could in fact be used to award merit pay increases. But nobody left the room feeling very comfortable that there would be any gain in what we knew made for good teaching.
  • Roughly half of the nation’s students are taking tests under NCLB that are completely free of open-ended questions.
  • educators have a strong incentive to “teach to the test.” In this case, that means teaching low level skills at the expense of the more demanding material that everyone says students need to master in today’s complicated world.
  • But is it fair to give students what amounts to a counterfeit passport to college or work? And do such tests spur high school teachers and principals to aim high with their students? To both questions, the answer is, “No.” In most states today, high school exit tests serve the same role as the standardized tests mandated by NCLB: they try to jack up the floor of student achievement in the nation’s schools. The best high school exit tests would be end-of-course exams akin to the “comprehensive” exams that many colleges and universities require students to pass in their majors before graduation – tests, that is, that would raise the ceiling of student achievement.
  • High-stakes testing has narrowed and dumbed down curricula; eliminated time spent on untested subjects like social studies, art, and even recess; turned classrooms into little more than test preparation centers; reduced high school graduation rates; and driven good teachers from the profession. Those are all reasons why FairTest and other experts advocate a sharp reduction in public school standardized testing and a halt to exit exams.
