This document summarizes research on the diffusion of mobile devices in education. It discusses how diffusion occurs through communication over time within a social system. Mobile devices provide benefits like anytime access to content and enhanced interaction, but also challenges like easier cheating and isolating non-technical students. Research found mobile devices can support 21st century skills if barriers to adoption are addressed. Key factors that influence diffusion include the perceived advantages, compatibility with current practices, and complexity of implementation. The document advocates for a decentralized approach led by teachers and targeting early adopters to reach critical mass.
