This book explores what can be accomplished when effective classroom techniques for teaching students to become good thinkers are combined with effective strategies to engage students in thoughtful learning of the regular secondary school science curriculum. The technique of lesson design and instruction that results is called infusing critical and creative thinking into content instruction. The infusion lesson design framework and the tools introduced in this handbook to facilitate designing and teaching infusion lessons are powerful devices to accomplish the basic objectives of education. The book is divided into six parts which include: (1) "The Design of Infusion Lessons"; (2) "Skillfully Engaging in Complex Thinking Tasks"; (3) "Skills at Clarifying Ideas: Thinking for Understanding"; (4) "Skills at Generating Ideas: Creative Thinking"; (5) "Skills at Assessing the Reasonableness of Ideas: Critical Thinking"; and (6) "Designing and Teaching Infusion Lessons".
