just to be clear: i was in the last class to take grade 13/oac.
i did not experience the changes that harris made to the curriculum, although the students in the grades below me did.
and, i have no understanding of this "new math" they speak of, or whether it's good or bad.
i don't think doug ford is the guy to fix the math curriculum, though. curriculums can't be glowered at. and, his own skills of arithmetic don't seem to be very good.
i would not be opposed, a priori, to implementing the recommendations of a study on the topic.
but, there is no royal road to geometry. the fact is that math is hard work, and if kids are failing then the problem is at home.
