My maths teacher made good use of the smartboards, using them to draw graphs and visually explain concepts.
it's a good teaching tool if ur teacher is like tech-savvy(again, not often), but most of the graphs can be done without it

"Mathematics is critical to modern life and it will be essential for formulating a response to the present economic crisis. Yet Australian school children are coming out of schools not knowing that doing a calculation with pencil and paper is the way to learn mathematics. While the federal Government is ploughing money into infrastructure,
we are staring at the vista of shiny new classrooms and rows of laptops with no mathematics teachers."
"As a mathematician and a parent, I do not understand why Australians must tolerate an education system that is inferior to that in America or Britain. Nor do I understand why we should accept a growing disparity in access to mathematics education across our school system. All Australian children deserve qualified mathematics teachers. Yet in Australia, policy-makers have either ignored the problems or taken only fragmented steps and half-measures to address them."
so my point is that if the government really wants to do something about it(which is unlikely, but I'm saying it anyway),
they should increase teachers' salary so that there would be more capable ppl willing to teach,
also when we have ATAR cut-offs as low as 70s for teaching, it's no wonder that some teachers aren't even smarter than the board
