Awesome Tutorials on how Teachers can Use Google Forms - 184 views

  • Google Forms is a great free service for us in education
  •  
    "Google Forms is a great free service for us in education. It is part of the free tools Google Docs offers to its users. Google Forms has a huge potentail for classroom teaching and teachers can do a myriad of tasks with it. As an example, instead of going looking for quiz forms others have created and that might not suit your teaching purposes why not learn how to create your own forms. Testing forms is just an example and of course there are many other things you can do with forms "

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.

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.

  • By 2021, schools must offer diplomas based students reaching proficiency in the four core academic subject areas: English, math, science and social studies. By 2025, four additional subject areas will be included: a second language, the arts, health and physical education.
  • proficiency-based idea has also created headaches at some schools for teachers trying to monitor students’ individual progress.
  • Students have more flexibility to learn at their own pace and teachers get time to provide extra help for students who need it
  • It wasn’t for lack of trying,” Bowen said. “It was a systems design problem.”
  • offer students clarity about what they have to learn and how they are expected to demonstrate they’ve learned it.
  • at schools that have embraced the new system, teachers say they are finding that struggling students are seeing the biggest gains because teachers are given more time to re-teach skills and students better understand the parameters for earning a diploma.
  • Deciding to believe that all students are capable of learning all of the standards, she said, “was scary.”
  • Multiple-choice questions have virtually disappeared. Homework is checked, but not graded.
  • students get less than a proficient score, they must go back and study the skill they missed. They are then given a chance to retake the relevant portions of the test until they earn a satisfactory score.
  • We inherited a structure for schooling that was based on time and on philosophical beliefs that learning would be distributed across a bell curve,

Activity 4: Writing comments - What you need to know | Edublogs Teacher Challenges - 88 views

  • Teaching quality commenting skills
  • If commenting skills are not taught and constantly reinforced, students will limit their comments to things like “I like your blog!” or “2KM is cool!”. While enthusiasm is high with these sorts of comments, students are not developing their literacy skills or having meaningful interactions with other members of the blogging community. Conversations in the comment section of a blog are such rich and meaningful learning experiences for students. Conversations begin with high quality comments.

  • How to teach quality commenting Kathleen teaches commenting skills through: Modelling and composing comments together with students on the interactive whiteboard. Teaching students about the “letter” format and editing process during writing lessons. Giving examples of a poor/high quality comments and having students vote whether the comment should be accepted or rejected. Example of a Sorting blog comments activity devised for our students here. Having students read and comment on a post on our blog as part of a literacy rotation on the computer each week. Taking students to the ICT room once a week to work on composing a quality comment with a partner. Emailing parents and encouraging them to write comments on the blog with their child.
  • Activities for developing student commenting skills
  • own or facilitate a collaborative discussion with students to create together (you could include this video as part of the process). Develop a quality comment evaluation guide.  Refer to Linda Yollis’s Learning how to comment. Write a blog post about commenting and what you define as a quality comment. Have your students practise leaving a “quality” comment on the post.
