This is one of those books that should be a must read for all teachers! Grounded in hours of observational and interview data from across the country, Ellin Oliver Keene puts forth a theory of engagement that is supported by curious joyful learning! Who doesn't want to be in a curious joyful classroom where purposeful relevant learning is taking place on a daily basis?! She first identifies the path to engagement from compliance to participation to motivation to engagement (noting that this path is not a linear progression, but that we can weave in and out of this path on our journey to engagement). Her theory of engagement is supported by four pillars: intellectual urgency, emotional resonance, perspective bending, and aesthetic world. For me, the pillars represent my teacher beliefs and I instinctively try to weave them into my daily instruction. But, having the pillars identified and described in detail give me much food for thought on how I can include the pillars in my classroom more intentionally, so they have a greater impact on student engagement, learning, and retention. LOVED this book!!!
