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…

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…

Eight students (ages 9-12) with mild mental retardation were instructed in sight-word reading in 2 small groups. Results showed that the time delay procedure was effective, that students learned other students' words through observation, and that students learned some incidental information. (Author/JDD)

Three fifth grade students with learning disabilities were taught to recognize multisyllabic basal vocabulary words using constant time delay in a small-group instructional arrangement and were assessed on ability to recognize, spell, and define both their own target words and observational words. The procedure was effective in establishing…

A study examined the acquisition of incidental information and observational learning of incidental information by 12 adolescents with moderate intellectual disabilities during school-directed systematic instruction. Results found participants learned 51.6% of the incidental information they observed during community-based or simulated dyadic…

Constant time delay was found to be an effective strategy in teaching targeted facts to four secondary-age students with mild and moderate mental retardation. Students also learned other students' target facts through observation and learned incidental information embedded in the consequent event following correct responding. (Author/JDD)

This study of two groups of four children (ages 6-9) with learning disabilities evaluated the effects of two contingencies (independent and interdependent) on the learning of students with learning and behavioral disabilities when conducted in small groups with constant time delay. Measures were collected on the rapidity with which children…

This study found that constant time delay was effective in teaching word reading to four students (ages seven to eight) with mild handicaps. Individual attentional response was more effective and efficient in learning to spell words than in choral attentional response. Observational and incidental learning occurred for all students.
