Models and frameworks help us better understand complex ideas and processes by providing a simplified explication of a concept, phenomenon, relationship, structure, system, or aspect of the real-world that allows us to focus on essential aspects of that which is being modeled. Relative to classroom technology integration, models can be useful in helping us understand and explain how technology integration occurs, allow us to better make decisions about how to effectively utilize technology resources, and provide insights that support development of strategies to more effectively and efficiently promote the kinds of pedagogical reforms that reformers hope to see in schools. The purpose of this chapter is to provide an overview of current models and frameworks that inform teacher adoption of technologies that support the integration of technology into student learning experiences in K-12 school settings, and to link them to theories of diffusion, adoption and change that underpin them.
