There is a whole discussion on this already.... Oh wait... Some Turkish dick ruined all that. They way teachers teach core subjects can be improved. Fundamentals not dumbing down. Certainly needs to be some measures in place. Luckily I have a number of ECE, primary teachers and DPs as friends and family. Seeing some of the methods they were teaching my boys for maths for example were a waste of time without them learning the core basics first. Trying to understand where they were and where they should be was far more difficult than it should have been and for me 'kids learn at different speeds' shouldn't be used as a reason not to be clear about this. And that's just the tip of it. Getting kids to school, making sure they are fed and participating, have the resources required, core skills, measured results, etc etc
It's clear that what we have currently is producing poorer results year on year, yet on we go.
