The Effects of Email Performance-Based Feedback on Teacher Candidate Implementation of a Multiple Stimulus without Replacement Preference Assessment

The purpose of this study was to evaluate the effects of performance-based feedback delivered via email on teacher candidates' implementation of a multiple stimulus without replacement (MSWO) preference assessment with an adult confederate. Six participants enrolled in a special education teacher preparation program were recruited to participate. After exposure to an introductory MSWO training video, participant fidelity of MSWO administration was measured. Following baseline, performance feedback was delivered via e-mail to each participant after the completion of each research session. Results indicate that performance feedback delivered via e-mail improved fidelity of implementation for all six participants. Implications and future directions are discussed.
