Connectivism - 1 views

  • These theories, however, were developed in a time when learning was not impacted through technology.
  • In many fields the life of knowledge is now measured in months and years.
  • ...29 more annotations...
  • The amount of knowledge in the world has doubled in the past 10 years and is doubling every 18 months according to the American Society of Training and Documentation (ASTD). To combat the shrinking half-life of knowledge, organizations have been forced to develop new methods of deploying instruction.
  • Technology is altering (rewiring) our brains. The tools we use define and shape our thinking
  • learning as a lasting changed state (emotional, mental, physiological (i.e. skills)) brought about as a result of experiences and interactions with content or other people.
  • Objectivism (similar to behaviorism) states that reality is external and is objective, and knowledge is gained through experiences. Pragmatism (similar to cognitivism) states that reality is interpreted, and knowledge is negotiated through experience and thinking. Interpretivism (similar to constructivism) states that reality is internal, and knowledge is constructed.
  • Behaviorism states that learning is largely unknowable, that is, we can’t possibly understand what goes on inside a person (the “black box theory”)
  • Cognitivism often takes a computer information processing model. Learning is viewed as a process of inputs, managed in short term memory, and coded for long-term recall.
  • Constructivism suggests that learners create knowledge as they attempt to understand their experiences
  • Constructivism assumes that learners are not empty vessels to be filled with knowledge. Instead, learners are actively attempting to create meaning. Learners often select and pursue their own learning. Constructivist principles acknowledge that real-life learning is messy and complex.
  • learning that occurs outside of people
  • The ability to synthesize and recognize connections and patterns is a valuable skill.
  • In today’s environment, action is often needed without personal learning – that is, we need to act by drawing information outside of our primary knowledge.
  • An entirely new approach is needed.
  • How can we continue to stay current in a rapidly evolving information ecology?
  • We can no longer personally experience and acquire learning that we need to act. We derive our competence from forming connections.
  • Unlike constructivism, which states that learners attempt to foster understanding by meaning making tasks, chaos states that the meaning exists – the learner's challenge is to recognize the patterns which appear to be hidden
  • The capacity to form connections between sources of information, and thereby create useful information patterns, is required to learn in our knowledge economy.
  • A network can simply be defined as connections between entities.
  • Nodes that successfully acquire greater profile will be more successful at acquiring additional connections
  • Finding a new job, as an example, often occurs through weak ties. This principle has great merit in the notion of serendipity, innovation, and creativity. Connections between disparate ideas and fields can create new innovations.
  • Connectivism is the integration of principles explored by chaos, network, and complexity and self-organization theories.
  • Learning and knowledge rests in diversity of opinions.
  • Decision-making is itself a learning process. Choosing what to learn and the meaning of incoming information is seen through the lens of a shifting reality. While there is a right answer now, it may be wrong tomorrow due to alterations in the information climate affecting the decision.
  • The starting point of connectivism is the individual.
  • This cycle of knowledge development (personal to network to organization) allows learners to remain current in their field through the connections they have formed.
  • the internet leverages the small efforts of many with the large efforts of few.

The children “listen to these “grandparents” better than they do their own parents, the mentoring really helps the teachers…the small efforts of the many- the seniors – complement the large efforts of the few – the teachers.” (2002). This amplification of learning, knowledge and understanding through the extension of a personal network is the epitome of connectivism.
  • Implications
  • The pipe is more important than the content within the pipe. Our ability to learn what we need for tomorrow is more important than what we know today. A real challenge for any learning theory is to actuate known knowledge at the point of application.

Edward R. Murrow - Wikipedia, the free encyclopedia - 0 views

  • See It Now focused on a number of controversial issues in the 1950s, but it is best-remembered as the show that criticized McCarthyism and the Red Scare, contributing if not leading to the political downfall of Senator Joseph McCarthy. On March 9, 1954, Murrow, Friendly, and their news team produced a half-hour See It Now special entitled "A Report on Senator Joseph McCarthy".[9] Murrow used excerpts from McCarthy's own speeches and proclamations to criticize the senator and point out episodes where he had contradicted himself. Murrow knew full well that he was using the medium of television to attack a single man and expose him to nationwide scrutiny, and he was often quoted as having doubts about the methods he used for the report. Murrow and Friendly paid for their own newspaper advertisement for the program; they were not allowed to use CBS' money for the publicity campaign or even use the CBS logo. Nevertheless, the broadcast contributed to a nationwide backlash against McCarthy and is seen as a turning point in the history of television. It provoked tens of thousands of letters, telegrams and phone calls to CBS headquarters, running 15 to 1 in favor. In a retrospective produced for Biography, Friendly noted how truck drivers pulled up to Murrow on the street in subsequent days and shouted "Good show, Ed. Good show, Ed." Murrow offered McCarthy a chance to appear on See It Now to respond to the criticism. McCarthy accepted the invitation and made his appearance three weeks later,[10] but his rebuttal only served to further decrease his already fading popularity.[11] In the program following McCarthy's appearance, Murrow commented that the senator had "made no reference to any statements of fact that we made" and contested the personal attacks made by "the junior senator from Wisconsin" against himself.[12]

      Rhapsody is awesome, but you should look into grooveshark.com. It follows the 'freemium' model discussed in class and has advertisements but I would like to hear what other people's experience is with it or any insights to how they make money.
  • Imagine if prices declined the further you went down the Tail, with popularity (the market) effectively dictating pricing. All it would take is for the labels to lower the wholesale price for the vast majority of their content not in heavy rotation; even a two- or three-tiered pricing structure could work wonders. And because so much of that content is not available in record stores, the risk of channel conflict is greatly diminished. The lesson: Pull consumers down the tail with lower prices.

  • And what this means is that if you look at a pedigree like this, and for example, here we have a mother and a father, girls are always round, boys are square. And here you'll see the mitochondrial DNA, it's donated to all of the children, but the fact is that these boys, when they mate, when they have offspring, they will no longer pass along her mitochondrial DNA, so it will be lost. And the only way the mitochondrial DNA can be transmitted is through one of her daughters, who in turn, have daughters.
  • Here's some other interesting principles. Mitochondrial DNA passes always from the mother, so when a fertilized egg is formed, Dad gives his chromosomes, but he doesn't donate for any, doesn't donate any mitochondrial DNA.
  • animals are related to one another. This is kind of a fun undertaking. Look at this. Why is it fun? Well it's, it's kind of an amusing idea, how often were cows domesticated during the history of humanity? How often were sheep domesticated? Pigs, water buffalos, and horses. And what you see here is that cattle were domesticated on two occasions, probably once in Western Asia, the middle east, and once in Eastern Asia. Sheep were domesticated twice, all modern sheep following these two families here

  • And that is, certain genes can evolve progressively over a long period of time, because they don't encode vital functions, or they may even be sequences between genes that don't encode phenotype at all. Imagine, for example, we have a situation were here we have a gene which encodes a vital function, like the eye, here's another gene that encodes another function, oh I don't know, a leg. And here we have intergenic sequences. After all, as you have learned by now, more than 96% of the DNA in our genome, doesn't encode proteins, and probably isn't even responsible for regulating genes. So these sequences, right in here, can mutate freely during the course of evolution, without having a deleterious effect on the phenotype of the organism. There's no evolutionary pressure to constrain the evolution of these genes
  • And many of these neutral mutations, which have no effect on organismic fitness, but are simply evolutionary neutral, are sometimes called polymorphisms. The term polymorphism, -morph is once again morphology, derives from the fact that species tend to be polymorphic, we don't all have blond hair, we don't all have brown eyes.
  • If you look at two chimpanzees living on opposite sides of the same hill in West Africa, they are genetically far more distantly related to one another, than any one of us, by a factor of 10 to 15. Two chimpanzees, they look exactly the same, they have the same peculiar habits, but they're genetically far more distantly-related than we are to one-another, than I am to any one of you, or than any one of you is to one another. And what does that mean? It means that, roughly speaking, the species of chimpanzees is, at least, 10 or 15 times older than our species are. We're a young species, chimpanzees probably first speciated three or four million years ago, if the paleontological record is, is accurate. Paleontology is the study of old, dusty bones, so you can begin to imagine when chimpanzee bones become recognizable in the earth.
  • And what you see already, in such small populations, is that for example, this male here has two girls, and right away, to the extent he had an interesting Y chromosome, that Y chromosome was lost from the gene pool. This girl, here, had an interesting mitochondrial DNA, but right away that's lost, because she has, she has just two boys. And what you see, in very rapid order, in small populations, there's a homogenization of the genetic compliment, just because the alleles are lost within what's called, genetic drif
  • And if you ask that question, the answer is that we all had a common ancestress who lived about 150,000 years ago. All of us trace our mitochondrial DNA to her. Does that mean that there was only one woman alive there, she's called, Mitochondrial-Eve, again, we don't know her name. Does that mean there was only one woman alive, well it doesn't mean that at all because of what I just told you, in small populations the proto-human population.
  • How much are all of our mitochondrial DNA are related to one another, how distantly related are they to one another, given the rate of evolution of mitochondrial DNA sequences?
  • So where do we all come from, all of us human beings? How closely related are we to one another? Here's, here's a measurement of the distances between different mitochondrial DNA's from different branches of humanity. And what you see is something really quite extraordinary and stunning. Here, you'll see that the people, the non-African lineages here and here, are actually relatively closely related to one another.
  • And by the way, all the genes that are present here, the alleles that are present here, can also be found in Africa, but in relatively small proportions in Africa
    • Erin Hamson
       
      Suggesting that all people came from Africa
  • So, what happens there, that's a testimonial to the tragic fate of the Indians, where the conquistadors from Spain came in, killed all the men, and took all the women, to be their brides. How else can you explain the fact that there's no Indian Y chromosomes, there's all, there is instead only European Y chromosomes.
  • When you do genetic counseling of family these days, one of the strictures is, that you never tell the family if the children have genetic polymorphisms that don't match that of the person whom they think is their father. They don't look like their, the person whom they regard as father, but that's always assumed to be a role of the genetic dice.
  • Here's a fun story I like to tell each year, and it's about the Cohen and Y chromosome, and you'll see what an amusing story this is, just from genetics. Now the name Cohen, in Hebrew means, a high priest, and you've heard people named Cohen, it's not such an uncommon name among the Jews. And it says, in the Bible, in Genesis and Exodus, that all the high priests in the Bible are the descendants of Aaron, the brother of Moses.
  • hen it should be the case that all male Cohen's should have the same Y chromosome, right?
  • Because keep in mind, any single affair with the milkman or the mailman, over 3,000 years, would've broke this chain of inheritance, any single incidence of non-paternity. It's a really astounding story, and it's hard, there can be no artifact to it, there's no bias in it, there's no other way to explain it.
  • And what they found was that all members of the, almost all members of the ruling cast among the Lembas, had the same Y chromosome, and the Y chromosome had exactly the same polymorphisms of the Cohen Y chromosome
  • What I'm telling you is that these two genes are totally interchangeable, that they are effectively indistinguishable from one another, functionally they have some sequence relatedness, but in terms of the way they program development, they are effectively equivalent. And what this means is that the progenitor of these two genes must've already existed at the time that the flies and we diverged, which six or seven-hundred million years ago, and in the intervening six or seven-hundred million years, these genes have been totally unchanged.
  • once the gene was developed, evolution could not tinker with it, and begin to change it in different ways, ostensibly because such tinkering would render these genes dysfunctional, and thereby would inactivate them, thereby depriving the organism of a critical sensory organ.

    An excellent discourse on who evolution works, and what it means for us today.

Twitter, Facebook, and social activism : The New Yorker - 2 views

      Do you agree with this?
  • This is in many ways a wonderful thing. There is strength in weak ties, as the sociologist Mark Granovetter has observed. Our acquaintances—not our friends—are our greatest source of new ideas and information. The Internet lets us exploit the power of these kinds of distant connections with marvellous efficiency. It’s terrific at the diffusion of innovation, interdisciplinary collaboration, seamlessly matching up buyers and sellers, and the logistical functions of the dating world. But weak ties seldom lead to high-risk activism.
  • The evangelists of social media don’t understand this distinction; they seem to believe that a Facebook friend is the same as a real friend and that signing up for a donor registry in Silicon Valley today is activism in the same sense as sitting at a segregated lunch counter in Greensboro in 1960.

  • Boycotts and sit-ins and nonviolent confrontations—which were the weapons of choice for the civil-rights movement—are high-risk strategies. They leave little room for conflict and error. The moment even one protester deviates from the script and responds to provocation, the moral legitimacy of the entire protest is compromised.

      But it was just a phone.
  • A networked, weak-tie world is good at things like helping Wall Streeters get phones back from teen-age girls.
  • These events in the early sixties became a civil-rights war that engulfed the South for the rest of the decade—and it happened without e-mail, texting, Facebook, or Twitter.
  • The cadre of prominent bloggers, like Andrew Sullivan, who championed the role of social media in Iran, Esfandiari continued, misunderstood the situation. “Western journalists who couldn’t reach—or didn’t bother reaching?—people on the ground in Iran simply scrolled through the English-language tweets post with tag #iranelection,” she wrote. “Through it all, no one seemed to wonder why people trying to coordinate protests in Iran would be writing in any language other than Farsi.”
  • “It is time to get Twitter’s role in the events in Iran right,” Golnaz Esfandiari wrote, this past summer, in Foreign Policy. “Simply put: There was no Twitter Revolution inside Iran.”
  • What mattered more was an applicant’s degree of personal connection to the civil-rights movement.
