The Replacement, Amplification, Transformation (RAT) framework is a technology integration model that helps instructors assess how their technology use serves their students and themselves. The RAT model was developed by Dr. Joan Hughes in 1998 to study how teachers integrated technology into their teaching practices. The framework identifies three primary purposes for technology integration: replacing existing practices, amplifying existing practices, and transforming teaching and learning through digital practices.

The RAT framework is organized around three themes and dimensions: instructional methods, student learning, and curriculum goals. Each of these themes has sub-dimensions that provide a more detailed understanding of how technology can impact teaching and learning. For example, under the instructional methods theme, there are dimensions for creating and organizing digital content, using technology to facilitate communication and collaboration, and leveraging technology to support student engagement and motivation.

The RAT framework provides a useful lens for evaluating the impact of technology on teaching and learning. By understanding the purposes behind technology integration, instructors can make more intentional decisions about how they use technology to support their students' learning. The framework also acknowledges that technology integration is not always transformative, and it is important to consider the benefits and drawbacks of technology use.

In summary, the RAT framework provides a structured approach to understanding the impact of technology on teaching and learning. By identifying the purposes behind technology integration, instructors can make more intentional decisions about how they use technology to support their students' learning.
