EDCP 342A - Instrumental Understanding vs. Rational Understanding



I'm not surprised to hear about the popularity of instrumental approach in teaching Mathematics. It reminds me of my non-Math friends that would often advise me to 'just practice' to ace exams during my undergrad. There is clearly more to Mathematics than the famous quote 'practice makes a man perfect'. 

Richard's proposition of teachers teaching different subjects under the umbrella of Mathematics is really interesting. I've always believed some teachers teach Math better than others. Furthermore, I absolutely agree with Richard in that knowing why a method works is as crucial as knowing the method itself. It reminds me of one of my colleagues that hates Mathematics but loves Physics. Although Physics and Mathematics are closely related, he strongly differentiates the two. In his mind, Physics makes sense, while Math does not!

If future Math teachers truly and deeply take the challenge of adding rational understanding along with instrumental understanding, we'll produce a generation of Math Lovers.
