Math and science are believed to be universal, so is there anything to decolonise in math and science education? Indeed there is. The wrong ‘belief’ that math and science are universal but developed mainly in the West played a key role in colonisation….
At this stage someone or the other (usually a non-mathematician) is bound to pop up with what seems (to them) an absolutely irrefutable objection. Is not 2+2 = 4 a universal truth? The simple answer is no. I am tired of explaining this repeatedly, but here goes once again. How much do 2 big fish + 2 small fish make? 3 big fish or 5 small fish?
Who said that? Please let me know if you wish to know!
