  • Impressive services
  • Only last week Google splashed out on Writely, a web-based word processor that requires no downloads or installation and just runs in a browser window.

  • Maybe Web 2.0 is a transitional phase, and once we get used to interacting with online tools in a more natural way and dispense with static web, we will move to a world of true distributed computing.
  • We'll need to make sure that the successful Web 2.0 companies don't just sit on progress because it doesn't serve their business plans, like so many other computing companies have done in the past and continue to do today. If Web 2.0 is the first stage in a revolution, we need to make sure it's a permanent revolution.

protocols internet history RFC open standards

  • We thought maybe we’d put together a few temporary, informal memos on network protocols, the rules by which computers exchange information
  • Less important than the content of those first documents was that they were available free of charge and anyone could write one. Instead of authority-based decision-making, we relied on a process we called “rough consensus and running code.”
  • Still fearful of sounding presumptuous, I labeled the note a “Request for Comments.”
  • ...5 more annotations...
  • the R.F.C.’s themselves took root and flourished. They became the formal method of publishing Internet protocol standards
  • Our intent was only to encourage others to chime in, but I worried we might sound as though we were making official decisions or asserting authority.
  • It probably helped that in those days we avoided patents and other restrictions; without any financial incentive to control the protocols, it was much easier to reach agreement.
  • This was the ultimate in openness in technical design and that culture of open processes was essential in enabling the Internet to grow and evolve as spectacularly as it has
  • we always tried to design each new protocol to be both useful in its own right and a building block available to others. We did not think of protocols as finished products, and we deliberately exposed the internal architecture to make it easy for others to gain a foothold.

  • 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.
  • example of a Maricopa County Community College system project that links senior citizens with elementary school students in a mentor program. 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.
  • acknowledges the tectonic shifts in society where learning is no longer an internal, individualistic activity

    Great article! It brings up some interesting points. This is something that I have thought about a lot lately, because with a lot of technology options today we don't even have to remember information, we can simply save it and have easy access to it later...just not in our brains but on our phones, computers, etc. Also, a really great reference to some interesting research that has been done with taxi drivers.

      I actually agree that some things, maybe even more things, should be free. But not as a marketing ploy. And this system seems to go against our capitalist ideals of competition.
  • The most common of the economies built around free is the three-party system. Here a third party pays to participate in a market created by a free exchange between the first two parties.

  • subscription model of media and is one of the most common Web business models.
  • Isn't it just the free sample model found everywhere from perfume counters to street corners?
  • the manufacturer gives away only a tiny quantity
  • A typical online site follows the 1 Percent Rule — 1 percent of users support all the rest.
  • Yahoo's pay-per-pageview banners, Google's pay-per-click text ads, Amazon's pay-per-transaction "affiliate ads," and site sponsorships were just the start.

      to me it's too much. we are spending our lives online in a world that can be valuable, but most of the time is not. it is so hard to balance time online with time doing other productive things. So much of our lives requires us to be on the computer, ugh.

  • Concurrently, we encounter problems that no one anticipated as we collectively built the internet as we know it today. This seminar will consider some of the most intriguing of the issues to which the advent of the internet has given and continues to give rise. It will focus on a cluster of topics about which any computer user likely knows a good deal already: spam, spyware, peer-to-peer file sharing, personal privacy, and e-commerce. It will also venture into a few issues-like blogging, RSS (Really Simple Syndication), social software, and internet filtering-that may be less familiar.

  • What are the limits of political protest in cyberspace, where the boundaries between public and private space are murky? How far can activists go without infringing on the rights of the people against whom they are protesting? As international reliance on computer technology increases, can anyone with a little technical know-how declare their own war?
  • 'In cyberspace, you don't have clear public byways intersecting private spaces, so there is no place to camp out and play your First Amendment card. If you try to deny service to someone else, by whatever means you use, you could be in pretty big trouble.'' The FBI spokesperson said that the use of Floodnet could constitute a federal crime: It is illegal to intentionally block access to an Internet server. But the members of the collective argue that they are simply gathering at the gateway, not chaining themselves to the door.
