I realise this is an old message, and you may or may not see it. However, I’ve been searching for answers on this topic and this thread came up. This answer bothers me and others might be reading it.
You’re a teacher and should know better. To call an able child lazy is not ok. Do you really know he can’t be arsed??? Or might it be that he has unidentified learning barriers that is preventing him from accessing the work?
Loving the own sound of his voice - maybe he’s neurodivergent and likes to talk about things he’s interested in but doesn’t read social cues to know when to stop.
maybe he doesn’t do the work because writing is really difficult physically and mentally or the work isn’t scaffolded to make sense to him and support him.
maybe YOU need to look at YOUR teaching strategies to help to motivate and support him rather than say he can’t be arsed.
your attitude is not ok. The way you describe him is shocking.
I was once the child that was called lazy and stupid. My mum knew I was ‘bright’ and had me tested by an EP and it turned out I was in the top 0.5% cognitively. That’s top 5 in 1000 peers. The EP also noted that I found it extremely hard to focus and needed tasks breaking down, needed rest breaks, needing motivation, reassurance, stretch, challenge etc etc. verbally I knew it all. I found exams super hard, due to slower processing speeds and interpreting the meaning of what questions were asking me for. Didn’t have extra time in those days. I’m now diagnosed Autistic and ADHD. I suspect I’m possibly dyslexic. I have a degree, masters, PGCE. Got a distinction in my masters since I could type it and no exams involved. I’ve burnt out because it takes me longer to do many things than the norm.
my son is similar. His teachers told me he’s meeting expectations. They tell me he stops when he’s done the bear minimum. He finds writing very difficult. It is extremely effortful for him. He’s been called lazy. His teachers last year wrote him off as he couldn’t be arsed. My son really can be. He gave up asking her for help. He makes lots of mistakes. He’d love to “make use of his knowledge and understand why he needed to apply himself to his school work” as you put it. He does know this now, because I support him with this understanding since his teachers don’t seem to realise he doesn’t get that connection if not explicit. He’s autistic, adhd and I suspect when I get his EP report (paid for privately to prove teachers wrong) I think it’ll reveal he has dyslexia and or dysgraphia. There is a mismatch between his ability and his application. He IS arsed. It’s not been picked up because some of his teachers see him as meeting expectations and they haven’t bothered to actually talk to him and realise his potential and support that. He should be greater depth. The school are failing him.
Be better. Learn about your children. Listen to what the parents say. They know their children. Perhaps your job share has a better gut feeling.
When a parent describes their child as bright, ask them for examples. Try to unpick what they find difficult at school.
