Technology is integral to teaching in the English language arts. This indispensable guide shows how to teach and model "digital diligence"--an alert, intentional stance that helps both teachers and students use technology productively, ethically, and responsibly. Resources and lesson ideas are presented to build adolescents' skills for protecting online privacy, minimizing digital distraction, breaking through "filter bubbles, " evaluating information on the Internet, and engaging in meaningful digital writing and reading. The book describes dozens of websites, apps, and other tools, with links at the companion website, and includes end-of-chapter teaching points and guiding questions.
