Book excerpt: "Kohn's analytical style ... is brought to bear on big-picture policy issues as well as small-scale classroom interactions. He looks carefully at research about homework, play, the supposed benefits of practice, parent involvement in education, and summer learning loss - discovering in each case what we've been led to believe doesn't always match what the studies actually say. Kohn actually challenges us to reconsider the goals that underlie our methods, to explore the often troubling values that inform talk about everything from the disproportionate enthusiasm for STEM subjects to claims made for "effective" teaching strategies."--Back cover.
