Misaki Number One!! (2011)

Both dramas are about teachers from unusual backgrounds teaching a group of kids who are "inadequate".

same plot line, different characters.

Yankees slowly changing for the better. Both dramas are warm with only happy endings. Not to mention they are both very funny and enjoyable.

it's the same plot, about students troublemakers whose nobody listen. And about one woman from totally different backround who wants to get them on right way of life as their teacher. And Johnny's boys act here too.

The exact same concept for both dramas: a rough inexperienced teacher is taken in by the principal to change the hearts of the students and the school culture while having a past that most wouldn't agree with. That fits both perfectly.

The themes behind these dramas are similar. The delinquent class meets a new teacher with a "past" and slowly begin to change for the better. Both dramas are bright, hope for the future sort of stories. They leave you with warm fuzzy feelings at the end.

Both dramas have jpop idols in the cast and a beautiful teacher trying to help the revolting teenagers.

A teacher who cannot leave her students alone. The difference is that Misaki's ways to help her students are easily seen as helpful and caring while Queen's Classroom has more of a deeper and darker meaning.

Dragon Zakura is a good kyoushi (bengoshi? ww) dorama and MNO!! is an annoying kyoushi dorama;
the thing I am basing this recommendation off is actually vaguely unrelated to any meaningful part of the shows' composition..: the kids' style
Osakaish GALish kinda bad thing; idk, it brightens me up
