  • The best results from computer-based learning are seen with Computer-Cooperative Pair Learning (0.96), where two students will work together to complete a computer-based learning task.

      This seems to be intuitively logical to me at this point. This results is likely not based on many meta-analyses. I'll have to look these up.
  • First, students are engaged through activation of a schema. Basically, setting the stage for learning something new by invoking things they already know.  Second, students do an experiment where they are allowed to “mess around” with a concrete phenomenon.  Third, an extensive class or tutorial discussion or activity takes place where students attempt to make sense of what they’ve seen.  This is the most critical stage, and must include scaffolding, guided questioning, modeling, shaping, concept mapping and so on.  Finally, having developed a set of principles or a theory, students are made to apply the theory to a novel problem or situation.  Some have formalized this learning cycle into four stages and an acronym: Activation (A; the set up), Concrete (C; the experiment), Invent (I; the discussion etc.), and Apply (A; the application to a novel problem); ACIA.

      Ah, yes.... learning cycles. This sounds much like the 5E approach to me.
  • direct instruction method (lecturing to small classes) gets a bum wrap that it doesn’t deserve.  It works very well provided instructors are versed in the proper use of questioning, scaffolding (building a mental framework to accompany the knowledge), and modeling (showing students good example of what they want and expect).

  • Second, PBL may be all the rage, but it’s a double-edged sword.  It works very well when worked, partially worked, and “to-complete” problems are used, and when schema are activated prior to commencement, but barely works at all when these things are not done.  PBL tutors require a greater degree of training than is currently the case if this method is going to be used effectively.
  • Third, don’t ignore the importance of giving students the chance mess around with concrete examples, particularly at the early stages.

    He lost me on the first paragraph with the stereotyping of university professors. The last 7 years have shown a major shift in accountabillity at the post-secondary level. Univiersities, colleges and for-profit education institutions must now show a return on investment for students like never before. Part of this is due to financial aid availability dependent on institutional graduation and post-graduation employment rates. Don't start an article dissing those who teach those who will serve in the elementary and high school classes.

  • “Unlike previous disruptions such as when farming machinery displaced farm workers but created factory jobs making the machines, robotics and AI are different. Due to their versatility and growing capabilities, not just a few economic sectors will be affected, but whole swaths will be. This is already being seen now in areas from robocalls to lights-out manufacturing. Economic efficiency will be the driver. The social consequence is that good-paying jobs will be increasingly scarce."
  • For those who expect AI and robotics to significantly displace human employment, these displacements seem certain to lead to an increase in income inequality, a continued hollowing out of the middle class, and even riots, social unrest, and/or the creation of a permanent, unemployable “underclass”.

  • “Just today, the guy who drives the service car I take to go to the airport [said that he] does this job because his last blue-collar job disappeared from automation. Driverless cars displace him. Where does he go? What does he do for society? The gaps between the haves and have-nots will grow larger. I’m reminded of the line from Henry Ford, who understood he does no good to his business if his own people can’t afford to buy the car.”
  • A consistent theme among both groups is that our existing social institutions—especially the educational system—are not up to the challenge of preparing workers for the technology- and robotics-centric nature of employment in the future.
  • “The jobs that the robots will leave for humans will be those that require thought and knowledge. In other words, only the best-educated humans will compete with machines. And education systems in the U.S. and much of the rest of the world are still sitting students in rows and columns, teaching them to keep quiet and memorize what is told to them, preparing them for life in a 20th century factory.”
  • Autodidacts will do well, as they always have done, but the broad masses of people are being prepared for the wrong economy.”
  • “Robots that collaborate with humans over the cloud will be in full realization by 2025. Robots will assist humans in tasks thus allowing humans to use their intelligence in new ways, freeing us up from menial tasks.”
  • “Many things need to be done to care for, teach, feed, and heal others that are difficult to monetize. If technologies replace people in some jobs and roles, what kinds of social support or safety nets will make it possible for them to contribute to the common good through other means? Think outside the job.”
  • And we can already see some hints of reaction to this trend in the current economy: entrepreneurially-minded unemployed and underemployed people are taking advantages of sites like Etsy and TaskRabbit to market quintessentially human skills. And in response, there is increasing demand for ‘artisanal’ or ‘hand-crafted’ products that were made by a human.
