Posting here as just not enough traffic on SEN forums!
DS (13) has inattentive ADHD and is on meds and they do help, but his tendency with written work is to skim read the questions, sometimes misunderstand them and answer the wrong thing, and to give brief, non-descriptive answers, although speech-wise he's very articulate and he is very bright.
Not surprisingly with ADHD (I know this is a thing) DS's brain just does not reward him for 'job well done' on learning tasks. DH gets exasperated that DS 'doesn't seem to care' and I keep trying to explain why and I think DS's ADHD gives him more learning challenges that DH's gave him as a child (DH doesn't have diagnosis but it's pretty clear he has ADHD as well), but that's by the by.
The one thing we have never managed well is consistency - DH because of his ADHD, me because I am running my life and the lives of two people with ADHD! I think we need to try, and maintain, a proper consistent routine of all devices being in the lounge when he gets home from school and him doing homework for a set time before there is any screen time. While checking in on him frequently to check he isn't stuck and staring into thin air. So if he has no internal motivation (for understandable reasons) we can at least offer him the carrot of screens after a few hours?
Does this sound like something that will help? Anyone else with ADHD teens who just cannot get down to it have any tips?
