This investigation examined the effectiveness of teaching letter sounds in a small group arrangement using computer-assisted instruction with SMART Board technology and a 3s constant time delay procedure to three students with learning disabilities. A multiple probe design across letter sound sets and replicated across students evaluate the effectiveness of the program and students' acquisition of other students' letter sounds through observational learning. In addition, students were assessed on their acquisition of incidental information presented in the instructive feedback statements following correct responses to target and nontarget stimuli. Results indicate that (a) the program was effective in teaching letter sounds to three students and (b) students acquired some letter sounds targeted for other students and incidental information (letter names) presented in the instructive feedback statements for their own and other group members' target stimuli. Findings are discussed in terms of presenting small group instruction through interactive white board technology. (Contains 3 tables and 3 figures.)
