Looking in the Wrong Places | Edge.org - 5 views

  • 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.

  • 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.

When Everything Clicks | Hidden Brain : NPR - 23 views

  •  
    This is a segment from NPR's HIdden Brain about Dr. Martin Levy's use of a clicker, usually used to train dogs, to train surgical students. It's fascinating. Essentially, the argument is made that clickers work so well because it is a form of feedback that does not use any verbal signals - no praise, no reprimand, no "good job," no "not like that." Praise and criticism distract a learner from mastering the skill being taught, making a learner focus instead on pleasing the teacher. With nonverbal feedback, the learner doesn't focus on the teacher but on the skill being taught

Technology Is Changing How Students Learn, Teachers Say - The New York Times - 13 views

  • hat the education system must adjust to better accommodate the way students learn, a point that some teachers brought up in focus groups themselves
  • roughly 75 percent of 2,462 teachers surveyed said that the Internet and search engines had a “mostly positive” impact on student research skills. And they said such tools had made students more self-sufficient researchers.
  • But nearly 90 percent said that digital technologies were creating “an easily distracted generation with short attention spans.”

  • About 60 percent said it hindered students’ ability to write and communicate face to face, and almost half said it hurt critical thinking and their ability to do homework.
  • Other teachers said technology was as much a solution as a problem.

The challenge of educating for unknown unknowns - The Learner's Way - 6 views

  •  
    It is almost precisely eighteen years since Donald Rumsfeld uttered his now well-regarded commentary on the danger of "unknown unknowns". At the time his remarks brought more confusion than clarity and reinforced for many a belief that politicians use words to conceal the truth. Somehow though, Donald's words from 2002 seem to fit the world of today, and the challenges confronting educators all too well.

      In my opinion this is very true, there are few if any directives on how teachers should be facing the changes in the 21st Century, everybody is still focused on hardware rather than cloud computing and web 2.0.

      Yes - it is a focus on the technology - as educaltors the focus should be on the pedagogy

    This isn't just about online learning! How many of these roles do you fulfill as a teacher, "facilitator," or admin? How successful have professional development efforts been in getting teachers to try out new roles? How successful have they been in getting kids to try out some of these roles? What other roles are there for students?

Contemplating the consequences of Constructivism - The Learner's Way - 21 views

  • learning is a process which occurs within the mind of the individual as they process stimuli arriving from their sensory buffer from their environment (broadly speaking), into working memory and onward into long-term memory.

  • The gradual release of responsibility model of instruction suggests that cognitive work should shift slowly and intentionally from teacher modeling, to joint responsibility between teachers and students, to independent practice and application by the learner

      Does not sounds like the classroom is empty? Classmates? Who cares about them?
  • It is not always the case that learning is best served when the process begins with direct instruction.
  • Schools provide a rich environment within which such learning may occur
    • Rafael Morales_Gamboa
       
      It is not always the case, and I would rather say that is not often the case, if our cultural legacy that depicts the school in literature and films.
  • best model can be to begin with an independent exploration of new content even when this produces failure
  • schools maximise their impact on the learning that occurs
  • constructivism urges teachers to ensure that the learner is at least as involved in the process as their teachers are
    • Rafael Morales_Gamboa
       
      I would call that "teacher-centred constructivism".
  •  
    Constructivism is one of those ideas we throw around in educational circles without stopping to think about what we mean by it. They are the terms that have multiple meanings, are at once highly technical and common usage and are likely to cause debate and disagreements. Constructivism in particular carries a quantity of baggage with it. It is a term that is appropriated by supporters of educational approaches that are in stark contrast to the opposing view; constructivism vs didactic methods or direct instruction. The question is what are the origins of constructivism and does a belief in this as an approach to understanding learning necessitate an abandonment of direct instruction or is this a false dichotomy?

Lydia Dobyns: A '21st Century' Education Is SO Last Century - 34 views

  • Of course, schools and classroom practices need to be current -- what teacher or district leader would say that we should continue to teach the way we did back in the "good ol' days?" Can you show me a successful organization or business that prides itself on keeping things exactly the way they were?
  • We need to believe the adults delivering education services are capable of being innovative, adaptive and collaborative and welcome being accountable for student outcomes. Then we need to invest in this belief by providing both the professional development and the infrastructure to make this belief a reality for all students and all teachers.
  • Ultimately, it is about delivering core education in today's world by today's standards of success.
  • I believe this is the basic approach: Education needs to be more relevant and rigorous for students. Educational institutions need to be more engaging and empowering for teachers. A high school diploma needs to be more directly applicable and valued in the economy. These are attainable goals; all education investments should be measured against these objectives.
