Hand Over Some Control

If students take ownership of what you do in class, then they have less room to complain (though we all know, it ll never stop completely). Take an audit of your class, asking what they enjoy doing, what helps them learn, what they re excited about after class. Multiple choice might be the best way to start if you predict a lot of nothingor watch moviesanswers.
After reviewing the answers, integrate their ideas into your lessons or guide a brainstorm session on how these ideas could translate into class.
On a systematic level, let students choose from elective classes in a collegiate format. Again, they can tap into their passion and relate to their subject matter if they have a choice.
