Does the Khan Academy know how to teach? - The Washington Post - 5 views

  • Gates has called Khan, "the best teacher I've ever seen.
    • djplaner
       
      An example of some of the large claims being made about Khan Academy that seem to suggest limited understanding of what makes a good teacher?
    • anonymous
       
      This is an interesting one - how can a teacher be hailed as such, when there is no real interaction (questioning from the student's point of view)? The Khan Academy does have its advantages as a very useful prop to specific lessons and concepts, yet the questions posed by any learner should be equally important if effective learning is to take place.
    • Margaret Johnson
       
      I agree Doreen, furthermore, the Khan Academy cannot be used as a stand alone to teaching, yet as a tool to extend understanding or to reteach concepts
    • Deb Mac
       
      It is a useful tool I agree. Students need to have an understand of a variety of ways/strategies/methods to draw upon in order to gain a full understand of the concepts.
    • Lisa Rose
       
      Interesting to see Bill Gates making a reference to teaching skills. Last I checked he wasn't an expert in education?!
    • robbie1282
       
      I don't get why they are making reference to Bill Gates I don't believe he has an understanding of teaching. Although these online library can help with understanding but is it really the way we want education to go online teaching??
    • djplaner
       
      I belive that the reference to Gates arises from the fact that he's spending a lot of his money attempting to improve schools and universities. That money means that his views on what is good teaching carry significant weight. More so than his qualifications and experience might otherwise warrant.
  • What is more, his videos reveal an ignorance of how we know students learn mathematics.
    • djplaner
       
      The Khan Academy videos suffer from the poor PCK of the people developing the videos. The core of the argument here.
    • Colleen Lenehan
       
      The videos were started to help students who were already learning through the school system and needed more help without having to pay for it. A lot of people are complaining about the videos as alternatives to explicit teaching in the classroom, but aren't they great for what they were originally designed for.
    • Kate Dugdale
       
      I don't think the Khan videos are doing any damage...They shouldn't be used as a stand alone, but instead as a supplement for learning, perhaps.
    • Louise Hoggett
       
      I think the videos are great as a supplementary activity, it provides a different way to explain something. Good on him for attempting it.
    • Lisa Rose
       
      I like David's comment: videos aren't actually evidence of the Khan academy, just "the poor PCK of the people developing the videos.".
  • Pedagogical content knowledge is an important foundation for planning lessons and for decision making during a lesson.
    • djplaner
       
      Building your PCK is essential to improving your ability to create effective learning experiences.
    • Lisa Rose
       
      I'm banging on the same drum here, but "building" to me is important - it's not the be all and end all.

  • All teachers make mistakes, after all, and Khan should not, the reasoning goes, be called out for making the same mistakes we all make.
  • There certainly are broken models in education, but there is absolutely no evidence that competent knowledge of student learning and thinking is one that teachers can afford to jettison.

    • Fran Gemmell
       
      How true, but how often do we see this and the reverse situation where teachers are teaching in areas where their content knowledge is lacking.
    • Lisa Rose
       
      Content is certainly the starting point and this is crucial.
    • Olivia Wirihana
       
      I agree content knowledge is crucial but there are so many more aspects needed to make it great.
    • sandra2812
       
      Content knowledge is important, but it doesn't matter how much knowledge a teacher has if s/he cannot teach that content in a way that the students will actually understand it and be able to apply it in future
    • traceydavis1968
       
      I agree that content knowledge is important but it is just as important to know your students and how best they learn
  • The standard American curricular treatment, in which students are instructed to append zeroes to the shorter decimal to equalize the number of digits helps students to perform this task correctly, but fosters its own misconceptions.
  • he exercises offer no intellectual rigor and do not address our central concern.
  • PCK knows from both educational research and professional experience
  • I think frankly, the best way to do it is you put stuff out there and you see how people react to it; and we have exercises on our site too, so we see whether they’re able to see how they react to it anecdotally.
    • Olivia Wirihana
       
      I think this comment is interesting as provocation has many benefits.
  • the examples Khan chooses appear selected at random and thus are, perhaps unsurprisingly, often quite poor.
    • sandra2812
       
      A teacher must be prepared before entering the classroom
  • If Khan’s videos occasionally popped up in a Google search, we would be content to have him carry on. There is lots of worse information available on the web. But Khan is hailed as “unbelievable” ( Bill Gates) and his work as “sparking a revolution in education
    • sandra2812
       
      It is up to the teacher to assess whether or not the videos are suitable for his/her students. If the teacher chooses to use the video, then s/her can refer to the teacher information and see which questions the students answered correctly / incorrectly and identify any misconceptions. These misconceptions can then be addressed by the teacher in the classroom
  • Whether small steps or large, we urge Sal Khan and his funders to put their time, effort and dollars to the best possible ends, particularly when it comes to making decisions grounded in accurate, carefully considered pedagogical content knowledge
  • discuss the meaning of the equal sign frequently and explicitly, and (2) model correct use of the equal sign.
    • Angela Woodward
       
      To quote a fellow student, Lucas Naughton states, 'ICT must be used to enhance and amplify the learning rather then becoming the point of the learning'. I get that there are holes in the Khan videos however if we are using them to enhance learning then why cant the teacher design an entire lesson around one video. They can discuss the missing misconceptions. They can provide other methods/concepts and they can create practice activities all around a Khan video. Remember-enhance and amplify the learning using these ICT's. Cheers Angela Woodward
    • djplaner
       
      Exactly. They can be a useful tool if used appropriately.
  • Khan will put the video out there and see how people react to it.
    • Kacey Howard
       
      There's no actual looking for student ability/interest - it seems as if he's more interested in teaching what he want to talk about.

    Wikipedia mentions Khan's education: "Khan attended the Massachusetts Institute of Technology, graduating with a BS in mathematics, a BS in electrical engineering and computer science, and an MS in electrical engineering and computer science in 1998. Khan also holds an M.B.A. from Harvard Business School" I can't see a Bachelor of Education in there. I would have thought that this would be essential, and the first stepping-stone, to acquire an understanding of PCK and how students learn. Danielson and Goldenburg state that "content knowledge alone is inadequate for quality instruction" and that many videos are prone to creating further confusion for students. They also go on to say that Khan's explanations are frequently off target in addressing likely student questions that experienced teachers would anticipate and elicit. Maybe a four-year stint at USQ might be in order? .

The Electronic Digital Computer - How It Started, How It Works and What It Does - NYTim... - 7 views

  • Whether it is solving a differential equation on the motion of charged particles or keeping track of a nuts-and-bolts inventory, the digital computer functions fundamentally as a numerical transformer of coded information. It takes sets of numbers, processes them as directed and provides another number or set of numbers as a result
  • Among the characteristics that make it different are the flexibility with which it can be adapted generally to logical operations, the blinding speed with which it can execute instructions that are stored within its memory, and its built-in capacity to carry out these instructions in sequence automatically and to alter them according to a prescribed plan.
  • Despite its size and complexity, a computer achieves its results by doing a relatively few basic things. It can add two numbers, multiply them, subtract one from the other or divide one by the other. It also can move or rearrange numbers and, among other things, compare two values and then take some pre-determined action in accordance with what it finds.

  • For all its transistor chips, magnetic cores, printed circuits, wires, lights and buttons, the computer must be told what to do and how
    • djplaner
       
      Increasingly there are algorithms that mean that the computer doesn't need to be told what to do. It is capable of learning. For example, in the past computers couldn't drive cars on the road. To do this the computer would have to be told how to do everything - accelerate, turn, how far to turn etc. The new algorithms are such that a computer (actually probably many computers) can drive a car without being told what to do (not a perfect analogy, but hopefully useful)
  • If the data put into the machine are wrong, the machine will give the wrong answer
  • Developing the software is a very expensive enterprise and frequently more troublesome than designing the actual "hardware
  • o specify 60,000 instructions
    • djplaner
       
      Facebook reportedly has at least 62 million lines of code (instructions) to make all of its features work.
  • This requires an input facility that converts any symbols used outside the machine (numerical, alphabetical or otherwise) into the proper internal code used by the machine to represent those symbols. Generally, the internal machine code is based on the two numerical elements 0 and 1
    • djplaner
       
      This applies to any data that an ICT uses - pictures, sound etc. It has to be converted into 0s and 1s (binary digits) that software can then manipulate
  • The 0's and 1's of binary notation represent the information processed by the computer, but they do not appear to the machine in that form. They are embodied in the ups and downs of electrical pulses and the settings of electronic switches inside the machine
  • The computational requirements are handled by the computer’s arithmetic-logic unit. Its physical parts include various registers, comparators, adders, and other "logic circuits."
    • djplaner
       
      This is the bit of the ICT that does the manipulation. Everything you do to manipulate data (e.g. apply Instagram filters) is reduced down to operations that an arithmetic-logic unit (ALU) - or similar - can perform

The Effects of Whiteboard Animations on Retention and Subjective Experiences when Learn... - 1 views

  • we found that whiteboard animations have a positive effect on retention, engagement and enjoyment, although we do not rule out the possibility that some of this result is due to novelty
  • While animations have a long history in the realm of education, and there is a plethora of research on instructional animations, attempts to measure their impact on educational outcomes have been inconclusive and often contradictory (Betrancourt, 2005)
  • For practical applications, however, the relevant question is not whether animations affect learning, but rather when and how animation affects learning ( Höffler & Leutner, 2007; Mayer & Moreno, 2002)
  • ...3 more annotations...
  • Thus, the goal of this study is to investigate the relative effectiveness of whiteboard animations on retention and subjective experiences of enjoyment, engagement, attention and challenge compared to more common and less costly instructional materials
  • Overall, we found significant positive effects of the use of whiteboard animation in conveying physics lessons
  • While encouraging, these findings suffer from some shortcomings: the lessons are all in one topic area, and the narration is, from the outset, conceived with animation accompaniment in mind, which may unfairly represent the other formats. This is a general enigma of media comparison studies; if you use the same material in all contexts, it may skew in favor of the context for which it was originally designed. If you don’t use the same material you cannot guarantee uniformity of experience.

  • Many mathematics educators stress another kind of knowledge necessary to design and deliver quality instruction: pedagogical content knowledge (PCK). PCK refers to knowledge of content as it relates to teaching.
  • This difficulty is due at least in part to the fact that many rules that apply to whole numbers do not apply to decimals. Perhaps the most famous of these involves comparing numbers. When two whole numbers have different numbers of digits (e.g., 435 and 76), the one with more digits is greater (and usually by a lot!) This is not true of decimals: 0.435 is less than 0.76, despite having more digits.
