Book excerpt: Expand your teaching repertoire with this unique collection of instructional ideas. Author Frank T. Lyman, Jr., esteemed educator and creator of the Think-Pair-Share model, offers ways to help students think critically, encounter puzzling phenomena and seek explanations, think before responding, listen to responses from others, create their own questions, visualize a scene, employ problem solving strategies, and more. Appropriate for teachers of all grades and subjects, the ideas address the pursuit of true learning--wanting to learn, how to learn, and enabling to learn--and can easily be adapted and applied to a wide variety of contexts. The book's format allows you to pick and choose activities for your own professional development journey and make them your own, so you can expand your teaching toolbox and bring more students to deeper levels of learning.
