This dissertation proposal examines how mobile technology can be used to inform and support a Response to Intervention (RTI) process for early literacy development in kindergarten students. The study will focus on how kindergarten teachers adopt and progress in their use of assessment technology to monitor student literacy skills. Data will be collected through teacher interviews, observations of technology use, student assessment scores, and surveys over the course of 5 months. The goal is to answer how mobile technology can support data-driven RTI and facilitate teacher adoption of assessment technology to improve early literacy.
