Robert Kaplinsky: Teaching Mathematical Problem-Solving Digitally

#EduDuctTape S03-E049

Episode Notes Available at: jakemiller.net/eduducttape-episode-49

  • 2 Truths & 1 Lie
  • Educational Duct Tape Question: "How do I teach mathematical problem solving digitally?"
    • "We are coming from a position where we have always taught it without technology, we should give ourselves a lot of grace."
    • In-N-Out burger question
    • Desmos Activity Builder for a real-world problem
      • Desmos has pre-built classroom activities, as well as the "Activity Builder" for making your own.
      • Use drag-and-drop editing to add content to an interactive slide deck (text boxes, sketches, graphs, etc.)
      • Slides can be oneway (providing info to students) or interactive (text questions, drag-and-drop, sketch, card sorts, etc.)
      • Can see an overlay view that is similar to what Pear Deck offers
      • Teacher.desmos.com
      • Desmos Marbleslides
      • Desmos can anonymize student names and freeze student screens
      • Sliders let students explore elements of problems, patterns, and graphs (for example, changing the m or b in y=mx + b)
    • "A lot of the way that we value mathematics in the United States is on getting the right answers quickly and efficiently. As a teacher, I was really good at creating math robots who could get the answers, but really didn't know what they were talking about."
    •  Focus on real-world problem-solving in mathematics → mathematical modeling
    • "It's easy to enter into, but challenging to master and that, I think, is very satisfying in general."
    • Open Middle Math
    • Open Middle with Desmos Activity Builder
    • The Dunning-Kruger Effect - "The more that you learn, the more that you realize you don't know."
  • The Celebration of the Adjacent Possible
    • Apple Podcast Review from Jated Bubbsy
    • #EduDuctTape Flipgrid Question from Andrew Nikola
      • microphones that I mentioned:
        • Samson Q2U Handheld Dynamic
        • Audio-Technica ATR2100
        • Audio-Technica ATR2100x
        • Blue Snowball
        • Blue Yeti
        • Rode
