The digital era has brought many opportunities - and many challenges - to teachers and students at all levels. Underlying questions about how technologies have changed the ways individuals read, write, and interact are questions about the ethics of participation in a digital world. As users consume and create seemingly infinite content, what are the moral guidelines that must be considered? How do we teach students to be responsible, ethical citizens in a digital world? This book shares practices across levels, from teaching elementary students to adults, in an effort to explore these questions. It is organized into five sections that address the following aspects of teaching ethics in a digital world: ethical contexts, ethical selves, ethical communities, ethical stances, and ethical practices.
