Sorry, but I’m calling absolute bullshit. Blackboards are fine for teaching maths according to mathematicians. For students, just look at stuff like 3blue1brown and summer of math and how many people finally get it because of animations and playing with the maths instead of some old dude drawing a formula on a blackboard.

This is like the pi vs tau debate.

I seriously do not understand why maths teachers are so unable to relate to their non-mathematically inclined students
