The projects conducted at the Tennessee Reading Research Center address all aspects of literacy across the lifespan and in different settings. Drawing upon the expertise of our faculty and staff, we conduct studies that examine how reading and writing develop among different learners, what instruction is most effective for improving literacy under what conditions, and how to measure students’ literacy skills in appropriate ways. These studies contribute to the body of knowledge referred to as the “science of reading.” We also are concerned with the preparation and ongoing support of literacy educators, so we conduct research on how to ensure that educators can implement effective practices in their classrooms, what models of preparation or professional development are most effective for strengthening literacy instruction, and how to measure educators’ literacy knowledge and skills in appropriate ways. These studies contribute to the body of knowledge referred to as “implementation science.”
