Purpose: To incorporate evidence-based practice into clinical settings, there is a need for efficient, effective ways to share information from research to speech-language pathologists (SLPs) and to students preparing to become SLPs. The purpose of this study was to implement and evaluate a method for teaching undergraduate student clinicians to use empirically supported practices in vocabulary instruction during shared storybook reading with preschoolers. Method: Undergraduate students enrolled in a semester-long preschool practicum participated in the study. In Study 1, 11 students participated in a multiple-baseline, single-case design. In Study 2, an additional 10 students were included in a quasi-experimental group design. All students completed prerecorded, online teaching modules that taught empirically supported practices for teaching vocabulary during shared storybook reading. Half of the students received weekly e-mails with performance feedback. Targeted practices included selection of appropriate vocabulary targets, explicit teaching, and use of interactive teaching strategies. Results: In Study 1, treatment effects were observed for targeted practices for many of the student clinicians. In Study 2, group comparisons indicated an effect of e-mail performance feedback for 1 of 3 outcomes with a large effect size. Conclusion: Prerecorded teaching modules may be an efficient, effective way to teach specific empirically supported practices to undergraduate student clinicians. E-mail feedback might improve use of taught practices for some students or for some practices. Future studies can examine the potential of these types of teaching modules for other outcomes or with groups of practicing SLPs.
