In highschool, at least, you have to somehow elevate the meaning of your subject to be more interesting than the movie theatre/concert/video game system they have in their pocket.

Kids will make eye contact with you and nod along as you teach, but they are wearing air pods and can't hear you over their spotify playlist.

Im not sure I can be more interesting than Taylor Swift, Call of Duty, MrBeast, and texting with friends all at the same time. You need the student to be a little bit receptive to even have the opportunity to convince them what you are teaching is relevant to them.
