Referred to Professor Jack Fletcher's work by Karina McLachlain, I find yet another conflict in language - I find the American habit of constructing long phrases and then reducing them to acronyms very irritating -and then this:
Instead, there was a branching off of children whose primary problem was behavioral (now called Attention-Deficit/Hyperactivity Disorder [ADHD]) and children whose primary problem was achievement.
So ADHD is simply policitally correct poor behaviour. I'd always thought so.
Professor Fletcher knows, however that there is a risk of people being assessed as having a learning disability when in fact they have not been properly taught. The US assessments try to tackle this by requiring documentation of the teaching the child has received, followed by assessments. The rub here lies in how much detail is given of this teaching.
RTI stands for "response to intervention", and is very similar to the wave approach adopted by the last government to SEN. In plain English, if you're falling behind in class (first tier or wave), you get extra help in a group (second tier or wave) and then if that doesn't work, you get individual help (third tier or wave). I'd like to see some experimental work that compared a short injection of focused individual support - and I don't mean the formulaic approach of Reading Recovery, that wastes so much time at the beginning, and then uses an out of date framework to impose its approach on teachers.
