We design inquiry-based curricula that send students out into the world to investigate, collect, report, reflect and engage. In doing so, students gain a sense of themselves as producers of knowledge. They become part of a continuous learning loop of inputs and outputs mediated by teacher and student alike. With basic mobile functions like voice, text and camera coupled with web 2.0 technologies, students’ knowledge can be shared locally and globally, all the while developing critical communication and collaboration skills. Audiocasting, photoblogging, polling, surveying and language acquisition are just a few of the activities that utilize mobile devices for learning. These are context-specific opportunities for students to share with authentic and limitless audiences. And for teenagers, to share is to be — which lies at the heart of their love for the cell phone to begin with.
