This negative perception definitely pre-dates Covid, but I personally think that Covid - specifically online school - has increased a perception that some teachers don’t do much outside that 09:00-15:00.
Anecdote I know, but my Y7 had the post Xmas period as online in second lockdown. The first lockdown was her Y6 - so I can’t say how the secondary handled that, but I can say that her Y7 experience wasn’t their first go.
Now it is not the fault or decision of her individual teachers that anything on a Teams call was voice only, and children muted and listening not talking. Those will be school and possibly Union decisions.
History: absolutely fantastic, the teacher talked to them for the full period (they could answer with messages despite being on mute).
Maths: taught / tested for 30 mins in every 1hr10 period. Pretty good - I don’t think he’d have held them longer.
French: no Teams calls at all, but very detailed feedback to written work, and recorded instructions on PowerPoints.
Every other subject? Zero teacher contact, no feedback on work, and in most cases fairly lame worksheet work set.
Now teachers here might tell me that the reality was that some of her subject teachers were managing key worker children.
Better still, they may have been involved in long 1:1 calls with older children nearing exams, or vulnerable children, or those who were academically slipping down a hole. Which would all be good reasons to leave my “average to good” well behaved non vulnerable child, who was completing her online (unmarked) work. She was absolutely the “safest” type of child to let slip.
But no-one communicated that. And so all the parents I know just say, “why the hell didn’t they have a single science “lesson” in all that time? That teacher did nothing.
All anecdotal and one school - but I’ve heard it from friends at other schools, and online comments. Some schools really gave the impression their teachers weren’t doing much… and a bit of PR would have gone a long way if that wasn’t the case.
