Friday Visual #34 - Global Issues of Olympic Proportions - 137 views

  •  
    In this set of visuals, graphic artist Gustavo Sousa uses the iconic Olympic rings to represent which continents have the most prisoners, HIV patients, McDonald's, and more. Naturally, the relative size of each ring correlates to the relevant data points. Would led to some great discussions with students.

Text Complexity Grade Bands and Lexile Bands | The Lexile® Framework for Reading - 42 views

  • 11–CCR  1070L–1220L 1185L–1385L
  • In the subsequent grade or grades within a band, students must "stretch" to read a certain proportion of texts from the next higher text complexity band. This pattern repeats itself throughout the grades so that students can both build on earlier literacy gains and challenge themselves with texts at a higher complexity level.
  • As students advance through the grades, they must both develop their comprehension skills and apply them to increasingly complex texts. The proportion of texts that students read each year should come from a particular text complexity grade band.

Doctoral degrees: The disposable academic | The Economist - 27 views

  • There is an oversupply of PhDs. Although a doctorate is designed as training for a job in academia, the number of PhD positions is unrelated to the number of job openings. Meanwhile, business leaders complain about shortages of high-level skills, suggesting PhDs are not teaching the right things. The fiercest critics compare research doctorates to Ponzi or pyramid schemes.
  • A graduate assistant at Yale might earn $20,000 a year for nine months of teaching. The average pay of full professors in America was $109,000 in 2009
  • America produced more than 100,000 doctoral degrees between 2005 and 2009. In the same period there were just 16,000 new professorships.
  • ...12 more annotations...
  • PhD students and contract staff known as “postdocs”, described by one student as “the ugly underbelly of academia”, do much of the research these days.
  • In some areas five years as a postdoc is now a prerequisite for landing a secure full-time job.
  • About one-third of Austria’s PhD graduates take jobs unrelated to their degrees. In Germany 13% of all PhD graduates end up in lowly occupations. In the Netherlands the proportion is 21%.
  • In America only 57% of doctoral students will have a PhD ten years after their first date of enrolment. In the humanities, where most students pay for their own PhDs, the figure is 49%.
  • in 1966 only 23% of science and engineering PhDs in America were awarded to students born outside the country. By 2006 that proportion had increased to 48%. Foreign students tend to tolerate poorer working conditions, and the supply of cheap, brilliant, foreign labour also keeps wages down.
  • The earnings premium for a PhD is 26%. But the premium for a master’s degree, which can be accomplished in as little as one year, is almost as high, at 23%
  • PhDs in maths and computing, social sciences and languages earn no more than those with master’s degrees
  • the skills learned in the course of a PhD can be readily acquired through much shorter courses.
  • In one study of British PhD graduates, about a third admitted that they were doing their doctorate partly to go on being a student, or put off job hunting.
  • The more bright students stay at universities, the better it is for academics. Postgraduate students bring in grants and beef up their supervisors’ publication records.
  • Writing lab reports, giving academic presentations and conducting six-month literature reviews can be surprisingly unhelpful in a world where technical knowledge has to be assimilated quickly and presented simply to a wide audience.
  • Many of those who embark on a PhD are the smartest in their class and will have been the best at everything they have done. They will have amassed awards and prizes. As this year’s new crop of graduate students bounce into their research, few will be willing to accept that the system they are entering could be designed for the benefit of others, that even hard work and brilliance may well not be enough to succeed, and that they would be better off doing something else.

    Use of iPads in MGT30700 (Project Management), Fall 2010 from Aug 23-Oct 8 Report Prepared by Corey M. Angst, Ph.D. & Emily Malinowski (MBA 2011) Mendoza College of Business, University of Notre Dame December 21, 2010 First, our findings suggest the greatest value of the iPad may not be its ability to function as an eBook reader but instead its capacity to function as a consolidator or aggregator of information. Second, a statistically significant proportion of students felt the iPad, 1) makes class more interesting, 2) encourages exploration of additional topics, 3) provides functions/tools not possible with a textbook, and 4) helps students more effectively manage their time.

Countries with greater gender equality have a lower percentage of female STEM graduates - 9 views

  •  
    "Countries with greater gender equality see a smaller proportion of women taking degrees in science, technology, engineering and mathematics (STEM), a new study has found. Policymakers could use the findings to reconsider initiatives to increase women's participation in STEM, say the researchers. Dubbed the 'gender equality paradox', the research found that countries such as Albania and Algeria have a greater percentage of women amongst their STEM graduates than countries lauded for their high levels of gender equality, such as Finland, Norway or Sweden."

Math - Online Calculator - Formula Library - 87 views

  •  
    My students in physics classes always come in with a broad range of math ability. Through the class, I teach and reteach a lot of math and sometimes understanding the content gets lost in the stresses of learning the math/algebra. Though to truely understand the interplay between rates and proportions involved a strong math background helps the content and big picture can be grasped even if the math must be buoyed. I hope this program assists my students this year to be more confident with the math so the physics concepts do not get lost.

Money Cuts Both Ways in Education - NYTimes.com - 19 views

  • 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.

'What's Wrong With Education Cannot Be Fixed with Technology' -- The Other Steve Jobs |... - 4 views

  • But I’ve had to come to the inevitable conclusion that the problem is not one that technology can hope to solve. What’s wrong with education cannot be fixed with technology. No amount of technology will make a dent.
  • It’s a political problem. The problems are sociopolitical. The problems are unions. You plot the growth of the NEA [National Education Association] and the dropping of SAT scores, and they’re inversely proportional. The problems are unions in the schools. The problem is bureaucracy.
  • You’d be crazy to work in a school today. You don’t get to do what you want. You don’t get to pick your books, your curriculum. You get to teach one narrow specialization. Who would ever want to do that?

  • It’s bad only if it lulls us into thinking we’re doing something to solve the problem with education.
  • The trouble is that education’s sociopolitical problems — its bureaucracies, its stakeholders, its poverty, as well as the sheer mass of the industry — are exactly what makes building a disruptive business around education so difficult.

The state of the Digital Union - - 9 views

  • This is an important speech on a very important subject. But before I begin, I want to just speak briefly about Haiti, because during the last eight days, the people of Haiti and the people of the world have joined together to deal with a tragedy of staggering proportions. Our hemisphere has seen its share of hardship, but there are few precedents for the situation we’re facing in Port-au-Prince. Communication networks have played a critical role in our response. They were, of course, decimated and in many places totally destroyed. And in the hours after the quake, we worked with partners in the private sector; first, to set up the text “HAITI” campaign so that mobile phone users in the United States could donate to relief efforts via text messages. That initiative has been a showcase for the generosity of the American people, and thus far, it’s raised over $25 million for recovery efforts.
  • Information networks have also played a critical role on the ground. When I was with President Preval in Port-au-Prince on Saturday, one of his top priorities was to try to get communication up and going. The government couldn’t talk to each other, what was left of it, and NGOs, our civilian leadership, our military leadership were severely impacted. The technology community has set up interactive maps to help us identify needs and target resources. And on Monday, a seven-year-old girl and two women were pulled from the rubble of a collapsed supermarket by an American search-and-rescue team after they sent a text message calling for help. Now, these examples are manifestations of a much broader phenomenon.
  • The spread of information networks is forming a new nervous system for our planet. When something happens in Haiti or Hunan, the rest of us learn about it in real time – from real people. And we can respond in real time as well. Americans eager to help in the aftermath of a disaster and the girl trapped in the supermarket are connected in ways that were not even imagined a year ago, even a generation ago. That same principle applies to almost all of humanity today. As we sit here, any of you – or maybe more likely, any of our children – can take out the tools that many carry every day and transmit this discussion to billions across the world.

Few Students Show Proficiency in Science, Tests Show - NYTimes.com - 18 views

  • Only one or two students out of every 100 displayed the level of science mastery that the department defines as advanced
  • a smaller proportion of American 12th graders demonstrated proficiency in science than in any other subject that the federal government has tested since 2005 — except history
  • Twenty-one percent of the nation’s 12th graders scored at or above the proficient level in science on the 2009 tests, compared with 42 percent who demonstrated proficiency on the most recent economics exam, and 38 percent and 26 percent, respectively, on the most recent nationwide reading and math tests.

Times Higher Education - Next-gen PhDs fail to find Web 2.0's 'on-switch' - 62 views

  • only a small proportion of those surveyed are using technology such as virtual-research environments, social bookmarking, data and text mining, wikis, blogs and RSS-feed alerts in their work. This contrasts with the fact that many respondents professed to finding technological tools valuable.Just under half of those polled used RSS feeds and only about 10 per cent used social bookmarking, with Generation Y students exhibiting the same behaviour as other age groups.

Comment le Royaume-Uni risque de perdre davantage en ayant triplé les frais u... - 1 views

  • Mais le taux d’impayés est récemment grimpé à 45 % au lieu des 28% à 30% prévus lorsque la réforme a été adoptée
    • Emmanuel Zilberberg
       
      Les opportunités gagnées par le gouvernement étaient claires. L'internalisation d'un coût supplémentaire par les étudiants représentaient des coûts évités en se transformant en actifs financiers sous forme de prêts à très long termes accordés aux étudiants. Le risque est que ces prêts ne soient pas remboursés et qu'ils faillent transformer une partie de ces créances (45%) en charges (pertes sur créances irrécouvrables).
  • Le gouvernement a, dans le même temps, réduit de 40 % ses subventions à ces établissements et promis aux étudiants des prêts à taux avantageux, d’une durée maximale de trente ans, garantis par l’Etat
    • Emmanuel Zilberberg
       
      L'abondement des prêts par le gouvernment britannique est la contrepartie de la diminution des subventions aux établissements créant ainsi des besoins de financement qui seront financés par les frais de scolarité augmentés.
  • apprend que le service d’Etat chargé de recouvrer lesdits paiements est assez peu outillé et efficace
    • Emmanuel Zilberberg
       
      Une partie des coûts de financement de l'éducation évité est compensé par l'accroissement des coûts de recouvrement de ces prêts.

  • Un effet pourtant bien prévisible et néfaste de la forte augmentation des frais d’inscription est la baisse, en 2012-2013, du nombre d’étudiants : -5,5 %, soit 27 000 nouveaux étudiants de moins qu’en 2011-2012
    • Emmanuel Zilberberg

  • de « full cost », qui consiste à faire payer aux étudiants le coût réel de leur enseignement
    • Emmanuel Zilberberg
       
      Il me semble que puisque le gouvernement britannique subventionne encore, bien que dans une proportion moindre, les universités, on ne peut prétendre qu'il s'agit d'une "expérimentation grandeur nature du concept de full cost"
