Free! The ARIZONA TECHNOLOGY INTEGRATION MATRIX provides a concrete framework and useful examples for fusing technology with pedagogical practice. The vertical axis of the 5x5 matrix takes its cues from Learning to Solve Problems with Technology: A Constructivist Perspective. The book, co-authored by a group of University of Missouri ed school professors, defines "five interdependent characteristics of meaningful learning environments": active, collaborative, constructive, authentic, and goal directed. The horizontal axis defines five levels of technology integration: entry, adoption, adaptation, infusion, and transformation. Each cell includes a teaching objective unique to its position within the matrix as well as sample lesson plans and videos for K-4, 5-8, or 9-12 classrooms.
