Had an interesting conversation with a parent of a child who has a diagnosis of ADHD a week or so ago. Along the lines of;
"He struggles with a class environment, too much going on, it sets him off....His ADHD is just awful"
"He doesn't struggle for me, the work he does is good, he gives great answers and is making good progress."
"What do you mean?"
"I'm pleased with him."
"....I don't understand....."
"He responds well to the boundaries and standards set, enjoys the praise he is getting for his efforts and is doing well."
".................."
I strongly suspect they tried to raise the kid on a tablet and wondered why he was bouncing off the walls.
