While I’m recommending books…. I recently read The Global Achievement Gap, by Tony Wagner, an excellent book about the failures of today’s secondary schools and how schools prepare students to memorize facts rather than problem solve. He identifies seven skills necessary to survive in the 21st century: critical thinking and problem solving; collaboration across networks; agility and adaptability; initiative and entrepreneurialism; effective oral and written communication; accessing and analyzing information; and developing curiosity and imagination. He takes “learning walks” through schools, and provides snapshots of school days, both good and bad. I wish every principal would read this book, take a learning walk of her/his own, and then implement many of the wonderful suggestions for ways to engage students in a meaningful way.
