This book is rambling, incoherent, repetitive, intellectually dishonest and manipulative. It presents a extreme, one-sided interpretation of the 1989 NCTM math standards as universally recognized, research-based "best practice."I would recommend that anyone choosing texts for a math methods course use the 2000 NCTM standards themselves and, if necessary, a generic teaching methods text.The 2000 Standards document is economical, beautifully done and, most importantly, far closer to a consensus of teachers, teacher educators, mathematicians and psychologists on what constitutes best practice than the 1989 document which inspires this text.
