Many parents have taken a defeatist approach toward understanding their teens, and not without good reason; it does often seem hopeless. But that’s where you, the volunteer youth worker, come in. Mark Oestreicher shows that Understanding Today’s Teenagers is both possible and rewarding, if one has the right tools. Marko explores the dimensions of nature vs. nurture, brain activity, culture, biology, and emotional development, all of which lead teenagers to do the wacky things they do that adults don’t understand and often can’t remember having done themselves. Marko also reminds us that adolescent development doesn’t end at the age of 18 just because United States law says it does.
