@jbradley I am not as strict with the cellphone rule because I do understand that work and family matters may arise for my students. However, I do make it very clear on day #1 that if you miss any information while I am lecturing and I see that you have been on your phone I will not repeat myself or answer your questions. I do not like to embarass my students when they are overusing their phones but I do let them know that they are missing lecture because they are too focused on their personal life and not the class content.
