Education is too subjective. I’ve been in the rooms where curriculum has been written. In fact, I’ve written curriculum that was used in my province. The truth is that most curriculum is developed on subjective opinions from “leaders” in all aspects of life. There are minimal axioms and principles used making decisions regarding education. Surveying the children doesn’t help either. How can they be expected to have foresight when none of us do?
Educational institutions are notoriously terrible at collecting data.
