The purpose of this study was to examine the impact of performance feedback on preservice teachers’ use of recommended practices within inclusive early childhood classrooms. A multiple baseline design across behaviors was used to examine the relation between performance feedback delivered via email and practicum students’ use of target-recommended practices across settings and over time. Results indicate performance feedback delivered via email is an effective method for increasing practicum teachers’ use of target behaviors; however, generalization and maintenance varied across teachers. Implications for professional development and future research are discussed.
