We don’t need to spend much time with calculation. Technology can do that for us. We can use the extra time saved for engaging in ‘higher-level’ thinking. Mr. Conrad Wolfram in his TEd Education Talk makes a lot of sense in this video. But, I have my reservations but not because I’m for teaching a lot of calculations.
We also said the same during the era of calculator. Did it improve the math education of our youth? So, what makes us think it will happen in the age of Mathematica, GeoGebra, Sketchpad? There is something in our math classes or math education that’s stuck in the middle ages, that’s not keeping with time. Unless we find and address this, no amount of technology can help us.
