Phones are a useful tool in education if we use them properly. Yes, there will be students who do stupid things with them but if we are patient and teach our students what we expect, proper usage and we monitor it, it can be very beneficial.
In my opinion, it seems that most us are scared to embrace new technology and new ways of doing things because it is not how we grew up doing it, so we make excuses as to why it could never work.

Students lose flip folders, music and lyres. But 99% of the time they always know where their phone is at. That could be a big plus for the students having all of the music for each game.
