    "We all hide things. From our friends and even from ourselves. Because of this, the pupils showing clear signs of distress and of need of social and/or emotional support are probably only a fraction of the real need at any one time. We also all experience difficulties at times, yet the object of our distress is often fleeting, or in hindsight trivial in the grand scheme of things. However, many of the young people we teach have chronically stressful situations to deal with on a daily basis, both at home and at school. This can exhibit in the classroom as anxiety, poor concentration or disruptive behaviour."

  • when they occur within a restricted-access network, do enjoy certain copyright advantages
  • we as a society give limited property rights to creators to encourage them to produce culture; at the same time, we give other creators the chance to use that same copyrighted material, without permission or payment
  • Did the unlicensed use "transform" the material taken from the copyrighted work by using it for a different purpose than that of the original, or did it just repeat the work for the same intent and value as the original? • Was the material taken appropriate in kind and amount, considering the nature of the copyrighted work and of the use?

  • the purpose of copyright—to promote the advancement of knowledge through balancing the rights of owners and users.
  • In some cases, this will mean using a clip or excerpt; in other cases, the whole work is needed. Whenever possible, educators should provide proper attribution and model citation practices that are appropriate to the form and context of use.
  • educators should provide reasonable protection against third-party access and downloads
  • educators using concepts and techniques of media literacy should be free to enable learners to incorporate, modify, and re-present existing media objects in their own classroom work

  • attribution, in itself, does not convert an infringing use into a fair one.
  • If student work that incorporates, modifies, and re-presents existing media content meets the transformativeness standard, it can be distributed to wide audiences under the doctrine of fair use.
  • When sharing is confined to a delimited network, such uses are more likely to receive special consideration under the fair use doctrine
  • there are no cut-and-dried rules (such as 10 percent of the work being quoted, or 400 words of text, or two bars of music, or 10 seconds of video).
  • Transformativeness, a key value in fair use law, can involve modifying material or putting material in a new context, or both
  • Copyright Act itself makes it clear that educational uses will often be considered fair because they add important pedagogical value to referenced media objects.
  • If educators or learners want to share their work only with a class (or another defined, closed group) they are in a favorable position
  • if work is going to be shared widely, it is good to be able to rely on transformativeness
  • courts have found that asking permission and then being rejected has actually enhanced fair use claims.
  • We don’t know of any lawsuit actually brought by an American media company against an educator over the use of media in the educational process
  • Lack of clarity reduces learning and limits the ability to use digital tools. Some educators close their classroom doors and hide what they fear is infringement; others hyper-comply with imagined rules that are far stricter than the law requires, limiting the effectiveness of their teaching and their students’ learning.

education grading

  • A professor who tells his students that “grades are the death of composition.” Another said: “Grades create a facade of coherence.”

      Interesting. I agree. I wish that we didn't have to grade student writing and could just give written or oral feedback. I love the "facade of coherence" comment.

      Key words. Grading is political.

      I like portfolios for demonstrating learning, but I haven't learned how to effectively integrate them into my own classroom.
  • most professors and students are much more likely to complain about grading than to praise its accuracy or value.
    • Dana Huff
      Dana Huff on 28 Jan 09
       
      Amen!
  • Done right, she said, eliminating grades promotes rigor.
  • the elimination of grades — if they are replaced with narrative evaluations, rubrics, and clear learning goals — results in more accountability and better ways for a colleges to measure the success not only of students but of its academic programs.
    • Ed Webb
      Ed Webb on 28 Jan 09
       
      This strikes me intuitively as correct. Grades are a substitute for thoughful assessment of learning outcomes, not an equivalent to it.
  • the idea of consistent and clear grading just doesn’t reflect the mobility of students
    • Ed Webb
      Ed Webb on 28 Jan 09
       
      Absolutely. My own institution, Dickinson College, sends ~70% of its students abroad for at least a semester, and most often a year. I have experience in education in different national contexts, and grading conventions simply do not translate.
  • ending grades can mean much more work for both students and faculty members.
    • Ed Webb
      Ed Webb on 28 Jan 09
       
      Aye, there's the rub. Those of us who are serious about learning - students and faculty - have to recognize that better learning is more work. On the other hand, it's more fun, too.
  • When faculty members are providing written, detailed analyses of multiple course objectives and are also — for majors — relating performance to larger goals for the major, so much more is taking place she said, than in a letter grade.
    • Ed Webb
      Ed Webb on 28 Jan 09
       
      Yes. Grades are a terrible assessment tool.
  • the training that colleges provide to professors before they start producing narrative evaluations, and officials of the no-grades colleges all said that training was extensive, and that faculty members needed mentors as they started out.
    • Ed Webb
      Ed Webb on 28 Jan 09
       
      And how much training do faculty get before they start handing out grades?
  • they end up favoring the evaluation system
    • Ed Webb
      Ed Webb on 28 Jan 09
       
      This is the point. Users have to be educated in the advantages of the system - once they have been, they are likely to favor it over grading.

NaturalScience senseperception paradigm

shared by Gareth Jones on 19 May 18 - No Cached
  • We should be very careful in thinking about whether we’re working on the right problems. If we don’t, that ties into the problem that we don’t have experimental evidence that could move us forward. We're trying to develop theories that we use to find out which are good experiments to make, and these are the experiments that we build.   We build particle detectors and try to find dark matter; we build larger colliders in the hope of producing new particles; we shoot satellites into orbit and try to look back into the early universe, and we do that because we hope there’s something new to find there. We think there is because we have some idea from the theories that we’ve been working on that this would be something good to probe. If we are working with the wrong theories, we are making the wrong extrapolations, we have the wrong expectations, we make the wrong experiments, and then we don’t get any new data. We have no guidance to develop these theories. So, it’s a chicken and egg problem. We have to break the cycle. I don’t have a miracle cure to these problems. These are hard problems. It’s not clear what a good theory is to develop. I’m not any wiser than all the other 20,000 people in the field.
  • I’m still asking myself the same question that I asked myself ten years ago: "What is going on in my community?" I work in the foundations of physics, and I see a lot of strange things happening there. When I look at the papers that are being published, many of them seem to be produced simply because papers have to be produced. They don’t move us forward in any significant way. I get the impression that people are working on them not so much because it’s what they’re interested in but because they have to produce outcomes in a short amount of time. They sit on short-term positions and have short-term contracts, and papers must be produced.
  • The field that I mostly work in is the foundations of physics, which is, roughly speaking, composed of cosmology, the foundations of quantum mechanics, high-energy particle physics, and quantum gravity. It’s a peculiar field because there hasn’t been new data for almost four decades, since we established the Standard Model of particle physics. There has been, of course, the Higgs particle that was discovered at the LHC in 2012, and there have been some additions to the Standard Model, but there has not been a great new paradigm change, as Kuhn would have put it. We’re still using the same techniques, and we’re still working with the same theories as we did in the 1970s.
  • ...10 more annotations...
  • That makes this field of science rather peculiar and probably explains why there hasn’t been much progress. But it’s not like we don’t have any questions that need to be answered. There are a lot of questions that have been around for decades. For example, what is dark energy? What is dark matter? What are the masses of the Standard Model particles? And what’s up with the foundation of quantum mechanics? Is a theory that's fundamentally not deterministic, where we cannot predict outcomes, the last word that we have, or is there something more to it? Is there maybe another underlying structure to reality?
  • but we haven't reached the fundamental level. Maybe we will never reach it. Certainly, the theories that we have right now are not all there is. The question is, of course, if we don’t have any guidance by experiment, how do we make progress? And are we doing the right thing?
  • We’ve reached this point where we have to carefully rethink if the criteria that we’re using to select our theories are promising at all. If one looks at the history of this field in the foundations of physics, progress has usually been made by looking at questions that, at least in hindsight, were well posed, where there was an actual mathematical contradiction. For example, special relativity is incompatible with Newtonian gravity. If you try to resolve this incompatibility, you get general relativity.
  • There are various similar examples where such breakthroughs have happened because there was a real problem. There was an inconsistency and people had to resolve it. It had nothing to do with beauty. Maybe beauty was, in some cases, the personal motivation of the people to work on it. There’s certainly some truth to this, but I don’t think it’s good to turn this story around and say that if we only pay attention to this motivation that comes from ideals of beauty it will lead to progress.
  • If we are working with the wrong theories, we are making the wrong extrapolations, we have the wrong expectations, we make the wrong experiments, and then we don’t get any new data. We have no guidance to develop these theories. So, it’s a chicken and egg problem. We have to break the cycle. I don’t have a miracle cure to these problems. These are hard problems. It’s not clear what a good theory is to develop. I’m not any wiser than all the other 20,000 people in the field.
  • The way that research is funded in foundations of physics and in many other fields just puts a lot of things at a disadvantage that are not pursued anymore. Typically, everything that takes longer than three years to complete, no one will start it because they can’t afford it. They can literally not afford it.
  • Who makes the decisions about the funding? Superficially, people say that it's a funding agency, so it’s the university who get to hire people. But that puts the blame on the wrong party. In the end it’s the community itself who makes the decisions. What do the funding agencies do if they get a proposal? They send it to reviewers. And who are the reviewers? They're people from the same community. If you look at how hiring decisions are being made, there’s some committee and they are people from the same community. They have some advisory boards or something, which contains people from the same community.
  • Even if that wasn’t so, what the people in these committees would be doing is looking at easy measures for scientific success. Presently, the most popular of these measures are the number of publications and the number of citations. And maybe also whether the person has published in high-impact journals. So, these are the typical measures that are presently being used. But what do they measure? They primarily measure popularity. They indicate whether somebody’s research is well received by a lot of people in the same community. And that’s why once a research area grows beyond a certain critical mass, you have sufficiently many people who tell each other that what they’re doing is the good thing to do. They review each other’s papers and say that that’s great and it's what we should continue to do. It’s a problem in all communities that grow beyond a certain size.
  • I later came to the United States and then Canada, and that gave me the opportunity to learn a lot about quantum gravity. I also figured out that much of what goes on in quantum gravity is very detached from reality. It’s pretty much only mathematics. Yes, the mathematics is there, but I still don’t know if it’s the mathematics that describes reality.
  • That’s the very reason why we don’t normally think of gravity as a weak force. It’s the only force that is left over on long distances, and the reason for this is that it adds up. It gets stronger the more mass you pile up. More precisely, we should say that the reason we find it so hard to measure quantum gravitational effects is that we either have a particle that has very pronounced quantum properties, like, say, a single electron or something like that, but then it’s so light that we cannot measure the gravitational field. Or we have some object that is so heavy that we can measure the gravitational field, but then it doesn’t have quantum properties. Okay, so that’s the actual problem.

NYTimes performance assessment teacher leaguetable

Kate Pok liked it
  • The rankings stem from a desire by policy makers to find an objective way to distinguish between effective and ineffective teachers, untainted by the subjective judgment of individual evaluators, like school principals.
  • Critics also say there are aspects of a child’s life — or distractions on test day — that the numbers cannot capture: supportive parents, a talented principal, the help of a tutor, allergies or a relentlessly barking dog outside the classroom.
  • there are schools where students are taught by multiple teachers, making it difficult to figure out the weight of their individual contributions

  • The union has warned that the result will be sweeping, with good teachers steering clear of grades that have standardized tests, parents’ attempts to switch their children to other classrooms, low morale among teachers and worse.
  • Roland Gesthuizen on 25 Feb 12
     
    After a long legal battle and amid much anguish by teachers and other educators, the New York City Education Department released individual performance rankings of 18,000 public school teachers on Friday, while admonishing the news media not to use the scores to label or pillory teachers.
