In this book, we describe the online world that youth begin to encounter, often without adult oversight. It is a critical time where they are first getting to know both the outside world and form their own identity. We explain the social forces and sways that influence kids' attitudes and choices, from peers in social apps to influencers. We show how the online world suggests answers that may or may not be right for individuals. Each chapter we supplies lessons that teachers, parents, counselors, and others can use to make youth aware of these online sways.
