Fixing math

Dan Meyer on fixing math education…

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. I saw this awhile back, and he definitely has some good points, but I couldn’t agree entirely with his approach. While math should certainly not be reduced to plug-n-chug and things of that sort, a vital part of learning math is adopting quantitative and formulaic approaches. If you remove all of the numbers and ask an open-ended question, you remove much of what is most valuable to the mathematical process in my opinion. An alternative approach that might be good is to incorporate some curriculum from Analysis, which explains WHY math formulas and theorems work the way they do, and could interest students who don’t really understand math at a fundamental level. That’s just my thought on the matter, however.

  2. A brilliant talk and a brilliant approach. To address the first commentor — I don’t think he’s advocating *only* this method. At some point you have to do the brute memorization (or brute learning of factoring a quadratic). For example you can’t have a conversation about multiples of something until you know your basic times tables…

    That being said, the biggest complaint in math classes is that people don’t see the point of it. This method addresses that complaint head-on, and I think it’s a great way to teach.

  3. The first problem with math education is the system — teachers have to teach the curriculum, and frequently they are mandated to teach to the specific book chosen by the school board.

    I think one needs to read Paul Lockhart’s essay A Mathematician’s Lament

    It expresses the opinions and thoughts of a PhD mathematician who teaching high school mathematics. Before the topic can be successfully discussed, you need to know what it is you wish to achieve, unfortunately the dire of mathematical understanding in public life is so severe, most people don’t understand what mathematics is.

    I’m not trying to be snobbish or elitist, but my mathematics education makes me painfully aware of the inequality of public awareness.

  5. @Craig – What Dan Meyer was describing here was how to take that mandated textbook and use it to teach math reasoning, by stripping out the hand-holding and formula-feeding.

    I thought it was great talk.
