The fundamental premise of "Thinkback" - based on overwhelming scientific evidence - is that intelligence is not fixed at birth and that, with consistent effort, we can dramatically improve our capacities. It counters the claims of some psychologists that it is impossible to increase intelligence because that ability is determined at birth. The book builds on the Think Aloud strategies in Arthur Whimbey and Jack Lochhead's popular and widely used volume, "Problem Solving and Comprehension", now in its 6th edition. Since its publication, thousands of students have used these techniques for improving thinking and analytic reasoning to increase test scores, win National Merit Scholarships, and gain admission to top-ranked professional schools. Now, "Thinkback" shows how these powerful strategies can be applied to a range of important academic areas including mathematics, language, arts, social studies and science. Thinkback is a tool for student empowerment - a strategy they can use to improve both their ablity to think and their ability to learn. The Thinkback classroom, on the otherhand, is a design for teacher liberation - enabling them to see learning more clearly than they ever could before. Th text contains detailed models of metacognitive dialogues in the classroom. These dialgoues enable teachers and teacher educators to observe thinking processes that previously had been invisible and undetectable. Based on over 20 years of careful cognitive research, the dialogues provide teachers with important insights into the nature of thinking and problem solving. Thinkback is a picture window on the working mind.
