Numerous studies have evaluated and confirmed many benefits of errorless learning and fluency-based procedures. The purpose of this study was to evaluate the benefits of combining an errorless learning procedure, stimulus shaping, and fluency-based procedures to teach see/say letter sound discriminations to three preschool children. Participants were taught 6 letter sounds using a hear/point stimulus shaping procedure followed by a see/say fluency-based procedure. A second letter set was taught using only the fluency-based procedure. Results showed that combining the procedures reduced the amount of teaching time by up to 40% and the percent of errors by up to 50%. This preliminary evidence shows exceptional promise in application of this combination of procedures to teach letter sounds to preschool children.
