This teaching guide provides an integrated framework for teaching thinking skills which involves both teaching thinking in a separate program or course and infusing the teaching of thinking into standard subject area instruction across the curriculum. Individual chapters deal with the following topics: (1) the nature of thinking skills and evidence that people can learn to think better; (2) the improvement of thinking; (3) kinds of thinking (broad categories, specialized kinds of thinking, metacognition, and some thinking frameworks); (4) the infusion of teaching thinking into regular subject-area instruction; (5) choosing and using separate instructional programs designed to teach thinking; (6) program development and selection of thinking skill goals; (7) lesson design and instructional strategies (structured thinking, teaching for transfer, and metacognition); (8) support systems for teachers and schools in the teaching of thinking; (9) approaches to evaluation; and (10) types of tests (objective and interpretive). (Individual chapters contain references.) (DB)
