Abstract
This study evaluated the effectiveness of using a 5 s constant time delay (CTD) procedure to teach the written spelling of social studies vocabulary words taken from the general education social studies content to students with mild disabilities. Subjects were 3 elementary students with mild disabilities. Instruction was delivered in a small group setting. Vocabulary words were different for each student, which allowed for observational learning by the other students in the group. Assessments of observational learning were conducted when each student attempted to spell their group-mate's words. Related instructive feedback (meaningful sentences containing the social studies vocabulary words) was presented in the consequent event of instructional trials. A multiple probe design across word sets was implemented to evaluate the effectiveness of the procedure. Results indicated that (a) CTD was reliably implemented and all students acquired the spelling of their own sets of 12 social studies vocabulary words with 100% accuracy and maintained this accuracy over time, (b) all students generalized their target spellings across settings and instructors, and (c) some observational and instructive feedback learning occurred for all students. Additionally, long-term maintenance of observational spellings decreased over time, and minor fluctuations in long-term maintenance of instructive feedback occurred.
