An Evidence-Based Approach To Science Education (Or: Dr. Hattie, And How I Learned To S... - 2 views

  • 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.

On Avocados and Presidents - nashworld - 1 views

    So, it happens that I was just checking out at the grocery store with my youngest daughter, Neve, by my side. While Neve danced around behind and beside me (literally), the checkout girl, who I could tell was quite green, asked if the bag of produce were avocados, "just to be sure." My reply:  "Yep… they sure are." I smiled warmly in an attempt to soften her subtle, but obvious discomfort in having to ask.

Avoiding "Unmitigated Disasters" - nashworld - 2 views

  •  
    "After stumbling upon the article, "Switch to e-books was 'an unmitigated disaster,' says school principal," in my feed this past week, it occurred to me that there are increasingly predictable patterns surrounding stories of failed "innovation" in digital learning initiatives. Schools have been assigning computers to each child for some time now. And still, we continue to see stories like this in the media. In short: we can do better than this."
