Many school districts are discovering that providing computer technology and using technology to improve student learning are two very different things. In this book, national experts use concrete examples to describe specific knowledge, beliefs, and strategies that will enable teachers and district leaders to support meaningful learning using technology. Chapters examine the intersection between course content, types of technology, and the supports and professional development required to effectively implement technology in the K-12 classroom. This authoritative volume: explores how technology can contribute to meaningful learning, achieving deep understanding of complex ideas that are relevant to students' lives; chronicles the effectiveness of specific technology-based curricula in the sciences and social studies, with a focus on history; and, suggests models and approaches for teacher professional development, including a "Meaningful Learning Toolbox" where teachers can co-author web-based curriculum units.
