This document discusses using smartphones and tablets (BYOD) in the classroom. It begins by asking questions about BYOD and defining it as students bringing their own internet-connected devices to class. It then discusses reasons to encourage BYOD, including keeping students engaged, easily gathering student data, and providing a study tool. Both arguments against and research supporting BYOD are presented. Examples of apps that can be used with BYOD like Nearpod, Socrative, SeeSaw, and Plickers are described. Potential issues with BYOD like access and technology problems are addressed. The document concludes by providing a checklist for determining if a technology is appropriate for one's teaching context.
