My dc is in year 8 at secondary. They seem to be in a class of consistently disruptive kids. Not bullying behaviour which I’m thankful for but answering back to the teachers, won’t listen to the teachers, throwing a table over, one teacher has refused to do (stopped partway through) 3 or 4 experiments with the kids because of too much chatting. Is this normal? Have things always been like this but I wouldn’t know? I’m worried about the impact on my dc’s education.
