An Ancient Retrovirus Has Been Found in Human DNA - and it Might Still Be Active - 0 views

  •  
    "Striking evidence has emerged that an ancient virus previously known only from fossil evidence has persistently infected some humans at very low levels for hundreds of thousands or even millions of years. This ancient retrovirus is a kind of living fossil, and the discovery of an intact copy of it within the human genome poses questions as to how it has survived, and suggests others from the distant evolutionary past may lie dormant in the DNA of many species. ..."

Teachers must ditch 'neuromyth' of learning styles, say scientists - 0 views

  •  
    "Teaching children according to their individual "learning style" does not achieve better results and should be ditched by schools in favour of evidence-based practice, according to leading scientists. Thirty eminent academics from the worlds of neuroscience, education and psychology have signed a letter to the Guardian voicing their concern about the popularity of the learning style approach among some teachers. ..."

15 Common Mistakes Teachers Make Teaching With Technology - 0 views

  •  
    "1. The teacher is choosing the technology. It's not always possible, but when you can, let the students choose, and see what happens. Not all of them will be able to. Some need help; so let other students help them. 2. The teacher is choosing the function. This doesn't mean you can't choose the function, but if you students can't control the technology the use nor its function, this can be problematic: the learning is passive from the beginning. 3. The teacher is determining the process. To an extent you have to, but don't overdo it. 4. The technology is distracting. If the technology is more magical than the project, product, collaboration, process, or content itself, try to muffle the bells and whistles. Or use them to your advantage. 5. The technology isn't necessary. You wouldn't use a ruler to teach expository writing, nor would you use a Wendell Berry essay to teach about the Water Cycle. No need for a Khan Academy account and a fully-personalized and potentially self-directed proficiency chart of mathematical concepts just to show a 3 minute video on the number line. 6. The process is too complex. Keep it simple. Fewer moving parts = greater precision. And less to go wrong. 7. Students have access to too much. What materials, models, peer groups, or related content do students actually need? See #6. 8. The teacher is the judge, jury, and executioner. Get out of the way. You're (probably) less interesting than the content, experts, and communities (if you're doing it right). 9. They artificially limiting the scale. Technology connects everything to everything. Use this to the advantage of the students! 10. They're not limiting the scale. However, giving students the keys to the universe with no framework, plan, boundaries or even vague goals is equally problematic. 11. Students access is limited to too little. The opposite of too board a scale is too little-akin to taking students to the ocean to fish but squaring of

Who's Asking? - Alfie Kohn - 0 views

  •  
    "It seems only fitting to explore the role of questions in education by asking questions about the process of doing so. I propose that we start with the customary way of framing this topic and then proceed to questions that are deeper and potentially more subversive of traditional schooling. 1. WHICH QUESTIONS? To begin, let's consider what we might ask our students. The least interesting questions are those with straightforward factual answers. That's why a number of writers have encouraged the use of questions described variously as "true" (Wolf, 1987), "essential" (Simon, 2002), "generative" (Perkins, 1992; Perrone, 1998), "guiding" (Traver, 1998), or "fertile" (Harpaz & Lefstein, 2000). What the best of these share is that they're open-ended. Sometimes, in fact, no definitive right answer can be found at all. And even when there is one - or at least when there is reason to prefer some responses to others - the answer isn't obvious and can't be summarized in a sentence. Why is it so hard to find a cure for cancer? Do numbers ever end? Why do people lie? Why did we invade Vietnam? Grappling with meaty questions like these (which were among those generated by a class in Plainview, NY) is a real project . . . literally. A question-based approach to teaching tends to shade into learning that is problem- (Delisle, 1997) and project-based (Kilpatrick, 1918; Blumenfeld et al., 1991; Wolk, 1998). Intellectual proficiency is strengthened as students figure out how to do justice to a rich question. As they investigate and come to understand important ideas more fully, new questions arise along with better ways of asking them, and the learning spirals upwards. Guiding students through this process is not a technique that can be stapled onto our existing pedagogy, nor is it something that teachers can be trained to master during an in-service day. What's required is a continual focus on creating a classroom that is about thinking rather

Poverty Impedes Cognitive Function | Science - 0 views

  •  
    "Burden of Poverty Lacking money or time can lead one to make poorer decisions, possibly because poverty imposes a cognitive load that saps attention and reduces effort. Mani et al. (p. 976; see the Perspective by Vohs) gathered evidence from shoppers in a New Jersey mall and from farmers in Tamil Nadu, India. They found that considering a projected financial decision, such as how to pay for a car repair, affects people's performance on unrelated spatial and reasoning tasks. Lower-income individuals performed poorly if the repairs were expensive but did fine if the cost was low, whereas higher-income individuals performed well in both conditions, as if the projected financial burden imposed no cognitive pressure. Similarly, the sugarcane farmers from Tamil Nadu performed these tasks better after harvest than before. Abstract The poor often behave in less capable ways, which can further perpetuate poverty. We hypothesize that poverty directly impedes cognitive function and present two studies that test this hypothesis. First, we experimentally induced thoughts about finances and found that this reduces cognitive performance among poor but not in well-off participants. Second, we examined the cognitive function of farmers over the planting cycle. We found that the same farmer shows diminished cognitive performance before harvest, when poor, as compared with after harvest, when rich. This cannot be explained by differences in time available, nutrition, or work effort. Nor can it be explained with stress: Although farmers do show more stress before harvest, that does not account for diminished cognitive performance. Instead, it appears that poverty itself reduces cognitive capacity. We suggest that this is because poverty-related concerns consume mental resources, leaving less for other tasks. These data provide a previously unexamined perspective and help explain a spectrum of behaviors among the poor. We discuss some implications for poverty policy."

Nativos digitales: del mito a la realidad, por @ferranadell en @CCCBLab - 1 views

  •  
    "... Durante mucho tiempo hemos dejado en manos del paso del tiempo la solución a las problemáticas educativas derivadas de la adaptación al entorno digital, pensando que serían los nativos digitales, a medida que estos poblaran las aulas, quienes provocarían el cambio necesario en los mecanismos docentes. Pero, como bien describen Benett, Maton y Kervin en The 'digital natives' debate: A critical review of the evidence, no hay ningún estudio que demuestre que los nativos digitales son más aptos, a priori, para el uso de la tecnología: la habilidad de los individuos está relacionada con las capacidades naturales, la formación y la experiencia, no con la fecha de nacimiento. El juicio que dice que los nativos digitales tienen un sofisticado conocimiento y unas altas capacidades para las tecnologías de la información debe ser, por lo menos, relativizado. ..."

Small Changes in Teaching: The Last 5 Minutes of Class - 0 views

  •  
    "The Minute Paper comes in many variations, but the simplest one involves wrapping up the formal class period a few minutes early and posing two questions to your students: What was the most important thing you learned today? What question still remains in your mind? Taken together, those two questions accomplish multiple objectives. The first one not only requires students to remember something from class and articulate it in their own words (more about that in a moment), but it also requires them to do some quick thinking. They have to reflect on the material and make a judgment about the main point of that day's class. The second question encourages them to probe their own minds and consider what they haven't truly understood. Most of us are infected by what learning theorists sometimes call "illusions of fluency," which means that we believe we have obtained mastery over something when we truly have not. To answer the second question, students have to decide where confusion or weaknesses remain in their own comprehension of the day's material. Closing connections. If we want students to obtain mastery and expertise in our subjects, they need to be capable of making their own connections between what they are learning and the world around them - current events, campus debates, personal experiences. The last five minutes of class represent an ideal opportunity for students to use the course material from that day and brainstorm some new connections.The metacognitive five. We have increasing evidence from the learning sciences that students engage in poor study strategies. Likewise, research shows that most people are plagued by the illusions of fluency. The solution on both fronts is better metacognition - that is, a clearer understanding of our own learning. What if all of us worked together deliberately to achieve that?Close the loop. Finally, go back to any of the strategies I introduced in my recent column on the first five minutes of clas

Small Changes in Teaching: The First 5 Minutes of Class - 0 views

    "Open with a question or two. Another favorite education writer of mine, the cognitive psychologist Daniel Willingham, argues that teachers should focus more on the use of questions. "The material I want students to learn," he writes in his book Why Don't Students Like School?, "is actually the answer to a question. On its own, the answer is almost never interesting. But if you know the question, the answer may be quite interesting." My colleague Greg Weiner, an associate professor of political science, puts those ideas into practice. At the beginning of class, he shows four or five questions on a slide for students to consider. Class then proceeds in the usual fashion. At the end, he returns to the questions so that students can both see some potential answers and understand that they have learned something that day. What did we learn last time? A favorite activity of many instructors is to spend a few minutes at the opening of class reviewing what happened in the previous session. That makes perfect sense, and is supported by the idea that we don't learn from single exposure to material - we need to return frequently to whatever we are attempting to master.But instead of offering a capsule review to students, why not ask them to offer one back to you?Reactivate what they learned in previous courses. Plenty of excellent evidence suggests that whatever knowledge students bring into a course has a major influence on what they take away from it. So a sure-fire technique to improve student learning is to begin class by revisiting, not just what they learned in the previous session, but what they already knew about the subject matter.Write it down. All three of the previous activities would benefit from having students spend a few minutes writing down their responses. That way, every student has the opportunity to answer the question, practice memory retrieval from the previous session, or surface their prior knowledge - and not just the students most likely to
