When trying to prove any technique, a teacher will grab one of these kids and show off how good they are and say it’s due to (insert any technique here).
I had one kid like this. As parents we patted ourselves on the back and thought we’d done something right.
My other kid is more typical or below typical and the style of learning makes a huge difference. Without that high articulation, they need a lot of work to understand phonics. Any system that leaves this out will only work for the kids who would’ve mastered reading anyway.
