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.

    "So we are entering this computer future; but what will it be like? What sort of a world will it be? There is no shortage of experts, futurists, and prophets who are ready to tell us, but they don't agree. The Utopians promise us a new millennium, a wonderful world in which the computer will solve all our problems. The computer critics warn us of the dehumanizing effect of too much exposure to machinery, and of disruption of employment in the workplace and the economy. Who is right? Well, both are wrong -- because they are asking the wrong question"

    There is a debate taking place in the world of education. It is not a new debate but recently it has gathered new energy and the boundary between polite discussion of opposing views and hostility has been stretched. The debate is that between those who are advocates of inquiry based learning and those who believe direct instruction produces the best outcomes. - This article explore how the debate has gone wrong and fails to serve the needs of learners.

    This sounds like an interesting article that someone took the time out to put up here on Diigo. There's only one problem, this seems to be some sort of "pay to view" site. Visitors actually cannot see the article in question (well, they get a 2-paragraph preview). Diigo friends, please don't point to sites that don't give the full information.

      I have always felt that focusing on what teachers do with technology instead of what students do with technology is the wrong approach. Unfortunately, many teachers feel they can't let their students use technology in the classroom unless they have somewhat mastered it themselves. I have learned a lot about how technology can transform learning by just letting kids spend some time exploring how a particular technology can be useful to them.

    Technology has been trying to 'revolutionize' education for a long time now. The mistake we've been making all along is placing all of the focus on the least important component of the revolution - the tech itself. It's where all the money goes and then what? Nothing left to actually ensure it's going to make the difference we want, with the the people we want to impact - the teacher and the student. It's happened all throughout education tech history in recent times. The film projector, the photocopier, the typewriter, the desktop and laptop computer, data projectors, interactive whiteboards, digital cameras were all heavily invested in ( and many still are today ) to bring engagement and improved teaching and learning to the educational world….But talk of the revolution is still going on. And now we have the tablet. The iPad has begun a new "education revolution" and now the obligatory opposition tech companies have joined the battle. The question has to be asked - are we again starting from the wrong end of the battle lines? Is the iPad (inserted alternative tablet if so desired) the real catalyst or is there so much more to this than money spending school systems can see beyond the new and shiny? It's why I ask the question: Is it the iPad, the App or the User?

  • suppose today’s content knowledge is an offshoot of successful ongoing learning in a changing world – in which ‘learning’ means ‘learning to perform in the world.’
  • Problem-based learning and the case method not only challenge the conventional paradigm but suggest that K-12 education is increasingly out of touch with genuine trends for the better in education.
  • the point of learning is not just to know things but to be a different person – more mature, more wise, more self-disciplined, more effective, and more productive in the broadest sense. Knowledge is an indicator of educational success, not the aim

    "if we think of action, not knowledge, as the essence of an education; let's see what results from thinking of future ability, not knowledge of the past, as the core; let's see what follows, therefore, from thinking of content knowledge as neither the aim of curriculum nor the key building blocks of it but as the offshoot of learning to do things now and for the future"

    At first glance, teachers may point to the fact that today's curriculum is not about content knowledge any more. It's about skill development, creativity, collaboration and communication. At a simplistic level, that may be partly true. We can't escape the fact, though, that accuracy and understanding is still paramount. While an 8 year old will survive making the odd misinterpretation or copying the wrong information down, a 20 year old medical student can't be confusing a pharynx with a larynx or thinking a 3:4 ratio means 3/4 and 1/4. So the question needs to be asked - How well are we dealing with Quality Control and Fact Checking in the Differentiated, Personalised Classroom? This one question brings up a whole lot more questions that every teacher needs t0 consider.

  • These 13-teacher and expert-tested strategies will strengthen your students' ability to find and use evidence from any text
  • Texts that inspire questions encourage students to return to the text and find support for their answers
  • starting with one overarching focus question
  • ...14 more annotations...
  • Require students to have evidence ready at the start of the discussion
  • "prove it"
  • evidence will actually open up a text to different interpretations
  • The challenge is getting students to expand and explain. To get students to explain why they choose a piece of evidence, provide them with a structure that moves from evidence to interpretation. Williams' students use a graphic organizer with three columns: They write their answer in the first column, note textual evidence in the second, and explain their evidence in the third.

      I want to do this!
  • Use sentence starters strategically
  • In the text ... the author mentions ...
  • the author uses this evidence to ... this lets us know that ...
  • Give students enough time to flip through and find just the right piece of evidence. If other students are getting antsy, choose one of your always-ready students to share, then loop back to the student who needed time with the text

      Good idea to keep the pace moving, while providing enough time to find better evidence.
    • deniseahlquist
      deniseahlquist on 17 Nov 14
       
      And if you encourage a collaborative atmosphere, having students ALL look for evidence related to each person's idea will mean they are all engaged in searching whenever anyone makes a claim. Either choose someone who has found it, or have them mark the page and keep searching for more evidence. Then have students ALL GO to the passage cited, so they can closely follow and respond with additional or conflicting evidence.
  • "Just because there's more than one right answer," says Riley, "doesn't mean there's no wrong answer."
    • deniseahlquist
      deniseahlquist on 17 Nov 14
       
      Part of what students do when they all look for evidence for each idea is to learn to weigh evidence for competing ideas and sift out "weaker" or unsupported answers from "stronger" claims. Brainstorming an idea that later doesn't pan out should not e seen as bad or wrong, but more accurately as the way idea-generating and sifting actually happens in many situations.
  • According to page
  • create an anchor chart

      Create and authentic anchor chart of student/teacher generated starters and prompts.
  • Listen for how students personalize the discussion, and encourage them to develop their own voice.
  • go back to the text
  • They answer the focus question a second time, explain whether or not they changed their answers, and reflect on how the evidence brought up during discussion impacted their thinking.

    I haven't taught sixth grade for 3 1/2 years now, but if I ever go back to ms, I'd incorporate this into my weekly plans. One way I get my second graders to grow their thinking is by having them respond to one another using the following prompts:  I agree with the part about…  Going back to what you said about…  One thing I noticed…  One thing I pictured…  It reminded me of…  I am not sure what you are saying. Could you say it in another way?  I agree with what you are saying because…  What you just said matches what is in my mind because…  I hear what you are saying, but I see it differently because…  If what you said is true, is it not also true that…  That is true, but… Or - That is true, and…  Could you say more?  Could you give me an example?  I would like to add on to what _________ said.  I have an example of what you just said.  I wonder why…  I was surprised to see…  Another thing that goes with that is…  So are you saying…

    We struggle to achieve balance with so many parts of our lives. We see things in dichotomies and try to weigh one against the other believing that we must give time to one and not the other. This tendency to see things in often false dichotomies leads to the problem of the "want to' vs the 'have to'. Unfortunately, when we are faced with this dilemma we often make a choice in favour of the 'have to' but we chose this option for the wrong reasons.
