grading assessment student-centered

shared by Brian C. Smith on 13 Apr 17 - No Cached
  • study showed that scores alone made students either complacent or unmotivated depending on how well they did. Scores with comments were just as ineffective in that students focused entirely on the score and ignored the comments. Surprisingly, it was the students who received comments alone that demonstrated the most improvement.
  • student self-assessment/self-grading topped the list of educational interventions with the highest effect size. By teaching students how to accurately self-assess based on clear criteria, teachers empower them to become “self-regulated learners” able to monitor, regulate, and guide their own learning.
  • The reason students never develop these traits is that our monopoly on assessment, feedback, and grading has trained students to adopt an attitude of total passivity in the learning process.

  • For some of us, the word gradeless means to grade less, that is, limiting the impact of grades within the context of current constraints. Some are just trying to get away from toxic assessment and grading practices, like assessments with no opportunity to redo or retake or zeroes on the mathematically disproportionate 100-point scale.
  • For others, gradeless means without grades, that is, avoiding the damaging and demotivating effects of grades entirely. These teachers are trying to put the focus squarely on learning, eliminating grades in favor of feedback and growth.

  • for example, learn to write short, tailored programs that can identify clusters of words and concepts in Supreme Court rulings more accurately than a Google search
  • Code, it seems, is the lingua franca of the modern economy.

  • One recent institutional adaptation is the creation of so-called CS+X initiatives at schools like Stanford, Northwestern and the University of Illinois. These programs are hybrid majors that combine computing with other disciplines, including anthropology, comparative literature and history — a nod to the reality that software skills can advance research in nearly every field.
  • Today, at many universities, at least half of the student population takes the intro courses.
  • coding as a window to “computational thinking,” which involves abstract reasoning, modeling and breaking down problems into the recipelike steps of an algorithm

      A challenge for certain, to parents, teens/students, and the community on the whole.

  • Independence isn’t free—you need some money in your pocket to pay for gas, or for that bottle of schnapps.
  • But iGen teens aren’t working (or managing their own money) as much.
  • Across a range of behaviors—drinking, dating, spending time unsupervised— 18-year-olds now act more like 15-year-olds used to, and 15-year-olds more like 13-year-olds. Childhood now stretches well into high school.
  • n an information economy that rewards higher education more than early work history, parents may be inclined to encourage their kids to stay home and study rather than to get a part-time job. Teens, in turn, seem to be content with this homebody arrangement—not because they’re so studious, but because their social life is lived on their phone. They don’t need to leave home to spend time with their friends.

      "may be inclined" - the author puts a lot on this statement as a possible source for this challenge we face. Parents rely no data trends get get their kids to stay home and study. I am sorry, the point may be true, yet I find it questionable parenting.
  • this means iGen teens have more leisure time than Gen X teens did, not less.
  • It’s not only a matter of fewer kids partying; fewer kids are spending time simply hanging out.
  • Teens who spend more time than average on screen activities are more likely to be unhappy, and those who spend more time than average on nonscreen activities are more likely to be happy.
  • Of course, these analyses don’t unequivocally prove that screen time causes unhappiness; it’s possible that unhappy teens spend more time online. But recent research suggests that screen time, in particular social-media use, does indeed cause unhappiness.
  • This doesn’t always mean that, on an individual level, kids who spend more time online are lonelier than kids who spend less time online
  • The more time teens spend looking at screens, the more likely they are to report symptoms of depression.
  • One piece of data that indirectly but stunningly captures kids’ growing isolation, for good and for bad: Since 2007, the homicide rate among teens has declined, but the suicide rate has increased. As teens have started spending less time together, they have become less likely to kill one another, and more likely to kill themselves.
  • This trend has been especially steep among girls. Forty-eight percent more girls said they often felt left out in 2015 than in 2010, compared with 27 percent more boys

    Does this fit the "Modern Learning" we are after? I appreciate the article and it provides a resource for discussion with kids, but I think it's more of a digital literacy item. I know, DL is a part of modern learning, but I'd like to see this space grow beyond just tech-focused items and push thinking about learning and teaching. On second thought... I have an alert for this group so I receive it in my email. Who's reading Diigo anymore anyway?

Computer Science Should Supplement, not Supplant Science Education - 0 views

computer science science NGSS CSTA

shared by Brian C. Smith on 18 Oct 16 - No Cached
  • In the integrated STEM classroom, using the principles of NGSS, educators are working to seek out real-world, relevant, authentic problems that would be of interest to students and ask them to apply computational thinking to solve the problem using data analysis, visualization, seeking patterns, and computation.
  • And as everyone knows, time in the school schedule is VERY limited and providing computer science as on a separate track cuts the instructional time pie even more, and sets up another silo in high schools.

  • They did exactly what I told them to do, blocking out racist, misogynist and anti-immigrant comments, hiding anyone who didn’t support Black Lives Matter, all with such deftness
  • I knew about Eli Pariser’s theory on filter bubbles, or the idea that online personalization distorts the type of information we see, and even so, I still chose to let algorithms shape how I perceive the world. Everything I could want to see is available at my fingertips, and yet I didn’t look.

  • Most social media
  • curated by software built to manage the high influx of information flowing into it
  • video-sharing app Vine was the first place I got a glimpse of cultures beyond my own
  • Vine links could be shared independent of the network, and people did so with abandon, meaning that Vines appeared scattershot around the web, defying the sorting mechanism of streams and feeds

      Vine's content did not necessarily need to go back to a central mechanism for oversight, like FaceBook & Twitter.
  • At Vine’s peak, it had more than 200 million monthly users who watched videos billions of times, and it excelled at showing these sorts of commonalities: that, say, black kids in New Orleans lived and looked a lot like white kids in Florida.
  • Snapchat offered its own version of cultural exchange.
  • People submitted short video diaries about life in their cities, which the company compiled into a single video, viewable by anyone using the app

  • User-generated content, by and large, is not lucrative at a scale that satisfies investors, and as a result, most social-media companies are changing direction toward other revenue streams

      User generated content by itself is less marketable. What exactly do they mean? Total user generated content without any "filters" or control is not a viable product?
  • Semiprivate messaging applications
  • have grown in popularity as people move away from public arenas for conversation, a shift caused in part by spikes in unchecked harassment on major social networks
  • What happens when we would rather look inward
  • We are more interested in locating alien species than understanding the humanity among the species we already live with
  • Social media seemed to promise a way to better connect with people; instead it seems to have made it easier to tune out the people we don’t agree with

      So do we ensure we/students have the skills to transfer jobs/roles easily? The challenge of manufacturing to healthcare is difficult. The ability to learn, stands at the forefront of skills to acquire.

  • but the effect on male employment was up to twice as big.
  • In an isolated area, each robot per thousand workers decreased employment by 6.2 workers and wages by 0.7 percent. But nationally, the effects were smaller, because jobs were created in other places.
  • If automakers can charge less for cars because they employ fewer people, employment might increase elsewhere in the country,

      Is this our experience that automaton enters the equation and prices get cheaper? That would be a great research project to look into.
  • cannot replicate human traits like common sense and empathy
  • new jobs created by technology are not in the places that are losing jobs, like the Rust Belt
  • From 1993 to 2007, the United States added one new industrial robot for every thousand workers — mostly in the Midwest, South and East — and Western Europe added 1.6.
  • like machine learning, drones and driverless cars — will have similar effects, but on many more people
