Diane Bryant, director of the Mathematics Institute for Learning Disabilities and Difficulties, explored the “RTI: Mathematics” module during a presentation with Deb Smith and Naomi Tyler at the November conference of the Teacher Education Division of the Council for Exceptional Children. Bryant was a consultant for the module, serving as the mathematics response to intervention (RTI) expert. Created by the IRIS Center at Vanderbilt University, the module is available free online. According to the IRIS Center website, the module “describes the RTI framework as applied to mathematics … [including] discussions of instruction, assessment, and data-based decision making at the primary, secondary, and tertiary levels.”
