Educational Leadership:Teaching for the 21st Century:21st Century Skills: The Challenge... - 119 views

  • the skills students need in the 21st century are not new.
  • Critical thinking and problem solving, for example, have been components of human progress throughout history
  • What's actually new is the extent to which changes in our economy and the world mean that collective and individual success depends on having such skills

  • Many reform efforts, from reducing class size to improving reading instruction, have devolved into fads or been implemented with weak fidelity to their core intent. The 21st century skills movement faces the same risk.
  • some of the rhetoric we have heard surrounding this movement suggests that with so much new knowledge being created, content no longer matters; that ways of knowing information are now much more important than information itself. Such notions contradict what we know about teaching and learning and raise concerns that the 21st century skills movement will end up being a weak intervention for the very students—low-income students and students of color—who most need powerful schools as a matter of social equity.
  • First, educators and policymakers must ensure that the instructional program is complete and that content is not shortchanged for an ephemeral pursuit of skills
  • Second, states, school districts, and schools need to revamp how they think about human capital in education—in particular how teachers are trained
  • inally, we need new assessments that can accurately measure richer learning and more complex tasks
  • Skills and knowledge are not separate, however, but intertwined.
  • In some cases, knowledge helps us recognize the underlying structure of a problem.
  • At other times, we know that we have a particular thinking skill, but domain knowledge is necessary if we are to use it.
  • if skills are independent of content, we could reasonably conclude that we can develop these skills through the use of any content. For example, if students can learn how to think critically about science in the context of any scientific material, a teacher should select content that will engage students (for instance, the chemistry of candy), even if that content is not central to the field. But all content is not equally important to mathematics, or to science, or to literature. To think critically, students need the knowledge that is central to the domain.
  • The importance of content in the development of thinking creates several challenges
  • first is the temptation to emphasize advanced, conceptual thinking too early in training
  • Another curricular challenge is that we don't yet know how to teach self-direction, collaboration, creativity, and innovation the way we know how to teach long division.
  • But experience is not the same thing as practice. Experience means only that you use a skill; practice means that you try to improve by noticing what you are doing wrong and formulating strategies to do better. Practice also requires feedback, usually from someone more skilled than you are.
  • We must plan to teach skills in the context of particular content knowledge and to treat both as equally important.
  • education leaders must be realistic about which skills are teachable. If we deem that such skills as collaboration and self-direction are essential, we should launch a concerted effort to study how they can be taught effectively rather than blithely assume that mandating their teaching will result in students learning them.
  • teachers don't use them.
  • Even when class sizes are reduced, teachers do not change their teaching strategies or use these student-centered method
  • these methods pose classroom management problems for teachers.
  • These methods also demand that teachers be knowledgeable about a broad range of topics and are prepared to make in-the-moment decisions as the lesson plan progresses.
  • constant juggling act
  • greater collaboration among teachers.
  • But where will schools find the release time for such collaboration?
  • professional development is a massive undertaking.
  • Unfortunately, there is a widespread belief that teachers already know how to do this if only we could unleash them from today's stifling standards and accountability metrics. This notion romanticizes student-centered methods, underestimates the challenge of implementing such methods, and ignores the lack of capacity in the field today.
  • The first challenge is the cost.
  • measures that encourage greater creativity, show how students arrived at answers, and even allow for collaboration.
  • When students first encounter new ideas, their knowledge is shallow and their understanding is bound to specific examples. They need exposure to varied examples before their understanding of a concept becomes more abstract and they can successfully apply that understanding to novel situations.

The Reading Brain in the Digital Age: The Science of Paper versus Screens: Scientific A... - 103 views

      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
    • Kris Cody
       
      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.

  • Participants in her studies say that when they really like an electronic book, they go out and get the paper version.
  • 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.

Gove unveils Tory plan for return to 'traditional' school lessons - Times Online - 22 views

  • a committee of the “greatest minds in Britain” would decide what children were taught. The Prince of Wales’ Teaching Institute would also be involved in drawing up a new curriculum.
  • “I’m an unashamed traditionalist when it comes to the curriculum,” Mr Gove said. “Most parents would rather their children had a traditional education, with children sitting in rows, learning the kings and queens of England, the great works of literature, proper mental arithmetic, algebra by the age of 11, modern foreign languages. That’s the best training of the mind and that’s how children will be able to compete.”
    • Ed Webb
       
      The best training of the mind?! Is he high?
  • “The invitation is there for all the great minds of our time to help reshape the national curriculum — both primary and secondary,” Mr Gove said. “We want to rewrite the whole thing and we are going to start as soon as we get in. We need the experts to tell us what is needed. The critical thing is to find people who want the intellectual life of the nation to be revived.”
    • Ed Webb

  • He’s absolutely right in saying that what draws people into teaching is that they love history or physics, and they want to communicate that love. They don’t love abstract thinking skills; they love the thrill of discovery in their own special field.
    • Ed Webb
       
      I love teaching. Come ask me.
  • “I was amazed to discover that science is not divided into physics, chemistry and biology. It has these hybrid headings about the chemical and material whatever and the Earth, the environment and this and that.”
    • Ed Webb
       
      Because, you know, hybridity is evil - EVIL! Interdisciplinary, inquiry-driven education is clearly a plot to weaken the moral fibre of the nation. Any increase in actual learning or interest on the part of students that it may produce must be an aberration.
  • Lessons should celebrate rather than denigrate Britain’s role through the ages, including the Empire. “Guilt about Britain’s past is misplaced.”
    • Ed Webb
       
      Has Mr Gove been reading Niall Ferguson? Or maybe taking lessons from recent French policy? Either way, bizarre and frightening.
  • I’ve been talking to the RSC about bringing Shakespeare into primary schools
    • Ed Webb
       
      More state funding for Shakespeare in schools I could get behind
  • Modern languages will also be revived. “One of the biggest tragedies in state education over the last ten years has been this huge drop in French and German, Italian and Spanish,”
    • Ed Webb
       
      More languages - good. But surely Chinese and Arabic should be high on the list? And Farsi, Urdu, Hindi, Russian...
