I ran across this wonderful exploration of the cell phone as a classroom tool rather than a annoying distraction. It is from 2007, and it is amazing how timely this still is for teachers, especially K-12 educators.
I’m putting in a link to the K-12 Online Conference site’s archive of Liz Kolb’s presentation as a resource for K-12 teachers and pre-service teachers. Like anything, this is not meant to be the one and only tool you use in the classroom, and – yes – you will need to tell students to put away their cell phones from time to time. But listen with an open mind to this former K-12 social studies teacher, and you may find a use for these mini-computers in your teaching practice.
