I met Lisa Nielsen, creator of The Innovative Educator blog, a year ago after learning of her stance on enabling students to use mobile phones in school as a learning device.
Proponents will say that you can't let kids use their phones because they might use them to take photos or video or text. I want them, and their teachers, to do just that when their school goes into lockdown, when their is an active shooter in their school, when they are witness to criminal behavior and anytime they need help.
