Maybe schools have to start having less hours and homework. I would come home from school after 5 pm and have tons of homework which I never did because who has patience for homework after a whole long day in school?!? The point of tons of homework is to “keep kids off the streets” but according to Teenager that seems to not be working.
Even kids who are not off the derech need to have fun. I was always very frum even in my very, very frum school, I was probably from the frumies but you know what?? I never liked school. I did not enjoy to study Chumash, Navi, etc. I also did not respect many of my “amazing” teachers and still don’t. (I had plenty excuse to go off the derech I think, but Torah is Emes so no excuse helps…) In any case, I don’t think these kinds of stuff is only for off the derech kids it’s for everyone. But really the underlying issues have to be addressed. If someone goes off the derech there is usually a reason behind it, not just that they want to hang out.
