The study employed a multiple probe design to investigate the effects of computer-based instruction (CBI) and a forward chaining procedure to teach manual spelling of words to three young adults with moderate intellectual disability in a small group arrangement. The computer-based program included a tablet PC whereby students wrote words directly onto a multi-touch screen. Words were projected onto a large screen in order to measure observational learning of other students' words. The study further evaluated acquisition of incidental information (reading target and observational spelling words) within the small group arrangement. Results indicated that students improved their spelling performance using the CBI package as well as their ability to read the grocery store words. Findings are discussed in the context of providing instruction in small group arrangements using commercially available technologies.
