As we started the second quarter here, one of my classes has gotten out of control. They won't stop talking, they show very little respect, and some refuse to do their work. This is partially my fault - they were a little chatty at the start of the year and I didn't do much about it, and now they are out of control. Lately, I've been much stricter and things are getting worse as they like to argue about the (very fair) consequences for their actions- should I try being nicer/playing games to try to win back their respect or stick with being strict? Thanks!
