John J. Hammerlink and the Really Big Think
by Bette Slater Seres
Recommended Ages: 5-9
This is a nice, small kid-friendly introduction to the thinking process, based in a very simple way on Bloom's taxonomy of learning objectives (knowledge, analysis, evaluation). Though no particular illustrator is credited, the pictures add a certain charm. I especially got a kick out of the two-page spread of John J. splashing in the mud puddle. He's a lovable little kid, and the friendliness and gentle humor of the book may make it really useful in an elementary school classroom.
Full disclosure: I was given a copy of this book when I interviewed the author for a newspaper story. Bette Seres is a first-time author and retired educator from Iowa (with a summer home up by me in Minnesota – hence the interview) and she told me she's planning a sequel in which John J. uses his imagination. I hope it won't take her the 20 years she said it took to write this book!
