Photo Tampering Throughout History - 1 views

  • Photo Tampering Throughout History Photography lost its innocence many years ago. In as early as the 1860s, photographs were already being manipulated, only a few decades after Niepce created the first photograph in 1814. With the advent of high-resolution digital cameras, powerful personal computers and sophisticated photo-editing software, the manipulation of digital images is becoming more common. Here, I have collected some examples of tampering throughout history. To help contend with the implications of this tampering, we have developed a series of tools for detecting traces of tampering in digital images (contact me at Ma'at Consulting for more information about our services). circa 1860: This nearly iconic portrait of U.S. President Abraham Lincoln is a composite of Lincoln's head and the Southern politician John Calhoun's body. Putting the date of this image into context, note that the first permanent photographic image was created in 1826 and the Eastman Dry Plate Company (later to become Eastman Kodak) was created in 1881. circa 1865: In this photo by famed photographer Mathew Brady, General Sherman is seen posing with his Generals. General Francis P. Blair (far right) was added to the original photograph.

In an Iranian Image, a Missile Too Many - NYTimes.com - 29 views

  • In a sentiment no doubt echoed by news organizations everywhere, an MSNBC editor acknowledged that the four-missile picture was initially welcomed with open arms. “As the media editor working the msnbc.com home page yesterday, I was frustrated with the quality of a fuzzy video image we published of the Iranian missile launch,” said Rich Shulman, the network’s associate multimedia editor. “So I was thrilled when the top image crossed the news wires.”

      Is hasty journalism going to continue to reduce the quality reporting? If a skilled graphic designer manipulated an image used by the news media could it be detected?

Fractals without a Computer! | Good Math, Bad Math - 32 views

  • We tend to think of fractals in computational terms, because in general we generate fractal images using digital computers. But you don’t need to. Fractals are actually fascinatingly ubiquitous, and you can produce them in lots of different ways – not just digitally.
  •  
    "In this video, what they've done is set up three screens, in a triangular pattern, and set them to display the input from a camera.. If you watch, they're able to manipulate it to get Julia fractals, Sierpinski triangles, and several other really famous fractals. "

Stephen Downes: Things You Really Need To Learn - 88 views

  • to educators, I ask, if you are not teaching these things in your classes, why are you not?
  • 1. How to predict consequences
  • The prediction of consequences is part science, part mathematics, and part visualization. It is essentially the ability to create a mental model imaging the sequence of events that would follow, "what would likely happen if...?"
  • ...18 more annotations...
  • 2. How to read
  • how to look at some text and to understand, in a deep way, what is being asserted (this also applies to audio and video, but grounding yourself in text will transfer relatively easily, if incompletely, to other domains).
  • 3. How to distinguish truth from fiction
  • Do not simply accept what you are told. Always ask, how can you know that this is true? What evidence would lead you to believe that it is false?
  • 4. How to empathize
  • this will allow other people to become a surprising source of new knowledge and insight.
  • 5. How to be creative
  • Sometimes people think that creative ideas spring out of nothing (like the proverbial 'blank page' staring back at the writer) but creativity is in fact the result of using and manipulating your knowledge in certain ways.
  • creativity involves a transfer of knowledge from one domain to another domain, and sometimes a manipulation of that knowledge.
  • pattern recognition can be learned
  • 6. How to communicate clearly
  • 7. How to Learn
  • Learning to learn is the same as learning anything else. It takes practice.
  • 8. How to stay healthy
  • 9. How to value yourself
  • You can have all the knowledge and skills in the world, but they are meaningless if you do not feel personally empowered to use them; it's like owning a Lamborghini and not having a driver's license.
  • 10. How to live meaningfully
  • When you realize you have the power to choose what you are doing, you realize you have the power to choose the consequences. Which means that consequences -- even bad consequences -- are for the most part a matter of choice

Students tap into technology - Pittsburgh Tribune-Review - 1 views

  • use their laptops to read "Don Quixote" and Dante's "Divine Comedy" on the Internet
  • Technology is the wave of the future
  • a computer program
  • ...7 more annotations...
  • "Most jobs require computers," noted Brittnee Stephen, 16, as she assembled a slideshow on her HP Mini laptop. "It's good that we're learning it now."
    • Ed Webb
       
      The technology is still very visible, if students are talking in terms of 'computers' rather than the skills involved. We don't talk about 'paper' but writing, critical reading etc. Yet here the platform itself is emphasized. Early days, I guess.
  • has just begun incorporating technology
    • Ed Webb
       
      Uh, no. They have been using 'technology' forever, in the form of, say, books.
  • students seem far more interested in learning via interactive technology than they had been with a chalkboard and an overhead projector
    • Ed Webb
       
      Well, the problem here is that some of that can be ascribed to novelty. Once every class uses 'interactive technology' (yuk) then how much difference will there be? The tools are great. All tools can be useful. But focus on the pedagogy, people!
    • Scott Merrick
       
      I'm for focusing on understanding. I love the word "pedagogy" because most lay people don't really know what it entails--theory (which can be anything institutional or community deems effective or correct), practice (which, as we know, can be summed up with the phrase "mileage will vary"), and some third thing which if I could come up with it I'd have the magic 3 elements in an effective argument. I think effective tools used effectively by effective teachers (there! 3 uses of one adjective!) will remain effective as long as they are used to promote understanding. No argument here, Ed, just sayin'...
    • Ed Webb
       
      Perhaps the magic third thing would be 'attitude' or 'state of mind'? Alternatively, perhaps another of those non-transparent terms, 'praxis'. The point I was trying to make, of course, was that it ain't what you use, it's the way that you use it.
  • "I think the kids that have turned school off because it's boring to them will come here and see something familiar,"
    • Ed Webb
       
      Boring and familiar seem to me to be closely related, not opposites. I suspect that often when students say their learning environment is 'boring' they mean 'challenging'.
  • Educational technology does not come cheaply
    • Ed Webb
       
      The cost of books is astronomical!
  • "Learning is changing,"
    • Ed Webb
       
      Was it EVER the case that we could "just deliver a lecture and expect all the kids to get it"?
    • Gregory Louie
       
      Computer technology in my classroom has revolutionized my teaching of biology. Instead of static images on a printed page, or talk and chalk, my students can manipulate 3-D images of DNA, RNA and proteins. These have even been embedded in a research-based learning progression that leads the students to a robust understanding of the foundational elements of molecular literacy. 1. Atoms and molecules are constantly in motion. (A visualization is not possible on a 2-3 printed page.) 2. All atoms and molecules have a 3-D structure that determines how they interact with other particles. 3. Charges and other intermolecular forces play a role in atomic and molecular interactions. My students can see these for themselves, change the number of particles in a box, or the distribution of charge on a large particle or the temperature of the box and other thought experiments which they can follow in real-time. There is no way, I could do that without the computer!

How to Adjust to your Interactive Whiteboard: The Chart Page « classroom2point0 - 106 views

  • How to Adjust to your Interactive Whiteboard: The Chart Page Interactive Whiteboards (IWBs) have the potential to draw your students into lessons in ways that weren’t possible without substantial planning, troubleshooting, and cut-and-paste work on your part. In this second of what will become more posts, I’ll teach you how to quickly make a “chart” page that you can use over and over again. Then I’ll provide suggestions on how this chart page can be incorporated into various content areas at the middle and secondary level. Why a “Chart” Page? A “chart” page is easy to make and easy for you and your students to manipulate. You will use this page over and over again. Once you’ve saved this page, you and your students can quickly and easily create flow charts, concept maps, and other graphical representations of key ideas and concepts.  As your students go to the IWB to demonstrate their thinking, you will find them more engaged and better able to retain information.

Optimism Bias: Human Brain May Be Hardwired for Hope -- Printout -- TIME - 62 views

  • manipulated positive and negative expectations of students while their brains were scanned and tested their performance on cognitive tasks. To induce expectations of success, she primed college students with words such as smart, intelligent and clever just before asking them to perform a test. To induce expectations of failure, she primed them with words like stupid and ignorant. The students performed better after being primed with an affirmative message. Examining the brain-imaging data, Bengtsson found that the students' brains responded differently to the mistakes they made depending on whether they were primed with the word clever or the word stupid. When the mistake followed positive words, she observed enhanced activity in the anterior medial part of the prefrontal cortex (a region that is involved in self-reflection and recollection). However, when the participants were primed with the word stupid, there was no heightened activity after a wrong answer. It appears that after being primed with the word stupid, the brain expected to do poorly and did not show signs of surprise or conflict when it made an error
