An Inconvenient Truth About Education: Rethinking the Way Things Are | Edutopia - 1 views

  •  
    Watching the Oscar-winning global-warming documentary An Inconvenient Truth, I was struck by the similarities between climate change and education change. These seemingly unrelated crises on our planet and in our schools are, in fact, connected. Both have taken many decades to develop and, at least in the United States, both originated in an industrial economy built on manufacturing. The effects of global warming and school decline are difficult to detect year to year, but over several generations, their impacts accumulate -- and are now converging to limit the future health of our economy and our society. To reverse these declines, similar fundamental shifts in thinking and behavior will be required at the individual, institutional, and societal levels. Consuming less, recycling more, and the ethic of caring for the environment should begin with our youngest children, as modeled by their parents, teachers, and caregivers. It's the same with literacy, curiosity, and a love of learning. Just as green technologies can make energy consumption more efficient, learning technologies can play a key role in modernizing the learning process.

After the boom, is Wikipedia heading for bust? - tech - 04 August 2009 - New Scientist - 0 views

  • The number of articles added per month flattened out at 60,000 in 2006 and has since declined by around a third. They also found that the number of edits made every month and the number of active editors both stopped growing the following year, flattening out at around 5.5 million and 750,000 respectively.

    So, is Wikipedia headed out? Some scientists have found that: "The number of articles added per month flattened out at 60,000 in 2006 and has since declined by around a third. They also found that the number of edits made every month and the number of active editors both stopped growing the following year, flattening out at around 5.5 million and 750,000 respectively." I have to wonder if their changes in who can edit has caused this shift. People still look at it (I do) to kick off research.

What Cliff? Data and the Destruction of Public Higher Ed | Just Visiting - 2 views

  • That higher education institutions are facing a “demographic cliff” in the coming years has become conventional wisdom. But what if there is no cliff? What if we’ve instead been subjected to a narrative rooted in limited data that serves the interests of corporations and is doing real damage to our public institutions?
  • Currently, the NCES projects relatively constant numbers of high school graduates through 2030, with total graduates expected to increase in the mid-2020s, followed by a modest decline, making the projected 2029–30 number slightly greater than in 2016–17. Further, it is important to note that since the 1970s, the total number of high school graduates in the U.S. has declined several times before. More importantly for higher education, the NCES projects modest increases in higher education enrollments through 2029.

  • The purported demographic crisis is being used around the country to fundamentally remake higher education. For example, this is the main argument being advanced by Republicans in the Wisconsin Legislature seeking to radically reshape the University of Wisconsin system. This plan calls for the significant expansion of online education, regionalization of the comprehensive campuses, increased campus specialization and program consolidation and elimination, among other long-standing priorities.
  • The current context of higher education provides fertile ground for the uncritical acceptance of the demographic cliff. Higher education enrollments have declined since reaching historic highs in 2010. And decades of political decisions have made higher education tuition-driven, one state budget cycle at a time. We are vulnerable to the demographic cliff framing because of the politically imposed financial crunch in which we exist. Enrollments dictate everything we do.
  • the demographic cliff is an austerity-driven narrative that assumes that public funding will never—and should never—come back
  • Programs must be eliminated, online education must be expanded and, if necessary, even entire campuses must be closed. Higher education must be agile because tax increases are off the table, even as stock markets reach new highs and the income and wealth of the highest earners skyrockets. The interests of corporations and the wealthy will dictate public policy.
  • official population and education data—which come with no political assumptions, narrative or products for sale—show a slowly increasing population, including higher education enrollments, in the coming years.
  • demographic cliff is a manufactured crisis
  • takes advantage of a tuition-dependent higher education system to implement even greater austerity while imposing an education policy agenda that could never be adopted through normal political means

Say Farewell To Google Reader | Fast Company - 7 views

    This is horrible news to most bloggers I know as many of us use Google reader and the apps that go with it like Mr. Reader and Feedly to pull information out of the web. RSS is one of the most useful features of Web 2 and I'm really unhappy w/ Google. iGoogle was a mistake, this a travesty. Google needs to read outliers and the mavens who use tools. I'll be researching new rss tools. This is ridiculous. ""While the product has a loyal following, over the years usage has declined. So, on July 1, 2013, we will retire Google Reader," Urs Hölzle, SVP Technical Infrastructure wrote. "Users and developers interested in RSS alternatives can export their data, including their subscriptions, with Google Takeout over the course of the next four months.""

Mixed Results on Paying City Students to Pass Tests - NYTimes.com - 0 views

    Information about paying people to pass ap tests.
  •  
    Paying kids to pass the AP test isn't working... but those supporting it say give it time. In some ways, money is the easy answer. But money doesn't solve problems when you have a child who has low self esteem. A child who is beaten every night isn't going to want to learn more during the day for a one time incentive... they feel trapped. Although the average improved (there were more "5's") - the overall pass rate declined slightly -- but more tests were taken. I am glad that people are willing to put money into trying new things, but sometimes I think teachers are left out of the equation. If we look at brain rules, improving the family life of kids and making sure they get more sleep are two of the most beneficial things we could to improve test scores.

Computer Science Teachers Association - CSTA Research - 1 views

  •  
    The new Computer Science survey is out from US high schools - the findings do not bode well for computer science: "the number of schools offering Advanced Placement Computer Science (AP CS) has declined significantly in the last six years. In 2005, 40 percent of respondents indicated AP CS was offered at their school. This number decreased to 32 percent in 2007 and to 27 percent in the 2009 survey. AP CS is in many cases the most rigorous course offered by schools. " I wonder how many programs are introducing programming concepts at other levels or using something like Scratch. Should Computer science just be defined as AP computer science?

Findings - Ethnographic Study Looks at Gossip in the Workplace - NYTimes.com - 4 views

  • once someone made a negative comment about a person who wasn’t there, the conversation would get meaner unless someone immediately defended the target.

  • Dr. Hallett found that the teachers became so comfortable with him and his camera that they would freely insult their bosses during one-on-one interviews. But at the teachers’ formal group meetings, where they knew that another teacher might report their insults to the principal, they were more discreet.
  • they sometimes offered obliquely sarcastic comments to test the water

Retaining older teachers for secondary education - Lessons from Holland? - 2 views

    "Not all teachers succeed in staying happy with their work until the end of their career. Dissatisfied older teachers will tend to quit before reaching retirement age.

Many Complaints of Faculty Bias Stem From Students' Poor Communicating, Study Finds - F... - 4 views

  • some perceptions of classroom bias would decline, and students would benefit more from exposure to opposing viewpoints, if colleges did more to teach argumentation and debate skills. Teaching undergraduates such skills "can help them deal with ideological questions in the classroom and elsewhere in a civil way, and in a way that can discriminate between when professors are expressing a bias and when they are expressing a perspective that they may, or may not, actually be advocating,"
  • The study's findings, however, were criticized as ideologically biased themselves by Peter W. Wood, president of the National Association of Scholars, a group that has frequently accused colleges of liberal or leftist indoctrination. The article summarizing the study, Mr. Wood said on Friday, "seems to me to have a flavor of 'blaming the victim,'" and appears "intended to marginalize the complaints of students who have encountered bias in the classroom."
  • Students need to learn how to argue as a workplace skill. If they understood this as a key workplace strategy that will affect their ability to advance they may be more willing to pay attention. They are there-- regardless of what we may believe-- to get jobs at the end. Discussion and dealing with disputes or differences is key to professional advancement

  • It's one thing to be closed to students' arguments or to insist on conformity with a prof's views.  It is another altogether when students do not know how to argue their own points, especially points that are not political.  At some point, isn't it the case that the prof does know even a little bit more about their subjects than their students?
  • Several studies (post 1998) seem to indicate that the capacity to understand and engage in logical argumentation has diminished (at least in the 'Western' world). These studies seem to have encouraged the state education boards (committees) of several states to entertain making a "critical thinking" or "Introductory logic" course part of the required core.
  • I have found Susan Wolcott's teaching materials, which are informed by research by K.S. Kitchener and P. M. King, to be the most helpful in addressing student accusations of bias.  I had long been puzzled by why my colleagues in philosophy are so often accused of bias when, in my own observation of their teaching, they take care to keep their own views of a philosophical topic hidden from students.  Indeed, they spend a great deal of time playing devil's advocate and championing the philosophical position that is getting the least airtime in class discussion, readily switching sides if another perspective begins to be neglected.  Wolcott's developmental analysis, which explains how students arrive at college as "confused fact finders" and often get stuck in learning critical thinking skills at the "biased jumper" stage, helps me to understand how students attribute bias to professors when the students lack skills to maneuver around arguments.  The most helpful part of Wolcott's analysis is her suggestion that, if one gives students an assignment that is more than one level above their current abilities in critical thinking, they will completely ignore the assignment task.  This failing is particularly visible when students are asked to compare strengths/weaknesses in two arguments but instead write essays in which they juxtrapose two arguments and ignore the task of forging comparisons.  In Wolcott's workbooks (available by request on her website), she describes assignments that are specifically designed to help students build a scaffolding for critical thinking so that, over four years, they can actually leave the "biased jumper" stage and move on to more advanced levels of critical thinking.  One need not be a slavish adherent to the developmental theory behind Wolcott's work to find her practical suggestions extremely helpful in the classroom.   Her chart on stages of critical thinking is the first link below; her website is the second link.   http://www.wolcottlynch.com/Do... http://www.wolcottlynch.com/Ed...
  • The classroom and campus are not divorced from the polarized language in the greater society wherein people are entrenched in their own views and arguments become heated, hateful, and accusatory.  The focus of this study on political bias is not helpful under the circumstances.  The greater argument is that students need to be taught how to argue effectively, with facts, logic and reasoning not just in the classroom but beyond.
  • What happened to the 'Sage on the Stage' as the 'provacatuer-in-chief'?  Some of my best classroom experiences came from faculty that prompted critical thinking and discussion by speaking from all sides of an issue.  They were sufficiently informed to deflate weak arguments from students with probing questions.  They also defended an issue from every side with factual information.  In the best instances, I truly did not know the personal position of a faculty member.  It was more important to them to fully and fairly cover an issue than it was to espouse a personal preference.  That spoke volumes to me about the love of learning, critical examination of strongly held personal beliefs, and assertive but fair-minded discourse.  Do those faculty still exist?
  • The study suggests that those faculty do exist and in fact are numerous, but that students' ever-diminishing skills in critical thinking and argumentation lead them to misunderstand the questioning, challenging Socratic dialogue and "devil's advocate" work of the professor as simple bias. 
  • When I was teaching controversial subjects the advice from the Administration was, "Teach the debate."  Its pretty hard to "teach the debate" without actually having some of those debates.  When students "checked out" during those debates I always wondered if they were the ones who were going to report on their teaching evaluations that, "the professor was biased."  Of course when the student intellectually "checks out," i.e., remains quiet, only says what they think I want to hear, etc., they are not doing A work in the class.  This reinforces their view that "the professor is biased."

  • This trend is especially prevalent in programs that serve low-income children. Compensatory early childhood programs such as Head Start and state-sponsored pre-kindergarten for low-income families and preschoolers with special needs are designed to help children acquire skills needed for later school success.
  • Beginning in the 1980s, leading early childhood experts expressed concern about the wisdom of overly didactic, formal instructional practices for young children (e.g., Elkind, 1986; Zigler, 1987). They feared that short-term academic gains would be offset by long-term stifling of children's motivation and self-initiated learning. Later research suggests that these early concerns were warranted

  •  
    A cross post from the original blog: As an avid Facebook user I'd have to give a big thumbs up to the consensus of the group. I, too, accepted friend requests from students and have stopped the practice. Our district developed a policy that strongly discourages teachers "friending" students on social networking platforms. This has made my life easier. When I receive friends requests I can decline and give them school policy as my reason. Students understand and it is never a big deal. It isn't just Facebook as I receive more friend requests through GoodReads. In response I am unrolling school GoodReads account for our learning commons, as well as a Facebook Group. This was we can be there for them in their network without crossing personal lines. Great discussion thread!
