The Technology Integration Matrix (TIM) provides a framework for describing and targeting the use of technology in any subject, not just mathematics, to enhance learning. The TIM incorporates five interdependent characteristics of meaningful learning environments: active, collaborative, constructive, authentic, and goal-directed. These characteristics are associated with five levels of technology integration: entry, adoption, adaptation, infusion, and transformation. Together, the five characteristics of meaningful learning environments and five levels of technology integration create a matrix of 25 cells. Developed by the Florida Center for Instructional Technology (FCIT), the TIM is in its second version.
