CiNii 図書 - Teaching for Understanding with technology

Teaching for Understanding with Technology shows how teachers can maximize the potential of new technologies to advance student learning and achievement. It uses the popular Teaching for Understanding framework that guides learners to think, analyze, solve problems, and make meaning of what they've learned. The book offers advice on tapping into a rich array of new technologies such as web information, online curricular information, and professional networks to research teaching topics, set learning goals, create innovative lesson plans, assess student understanding, and develop communities of learners.
