Dr. Ted Hasselbring is a Professor of Special Education at Peabody College of Vanderbilt University and author of READ 180, System 44, and FASTT Math. Over the past 25 years, Dr. Hasselbring has conducted research on the use of technology for enhancing learning in students with mild disabilities and those who are at-risk of school failure. Dr. Hasselbring developed the research-validated FASTT algorithm (Fluency and Automaticity through Systematic Teaching with Technology) to build fact fluency—retrieval of facts with accuracy, automaticity, and understanding—which is incorporated in READ 180, System 44, and FASTT Math. For MATH 180, Dr. Hasselbring shares his expertise in adaptive technology to build a personalized learning experience for struggling math students.
