Children with developmental disabilities are trained using different teaching arrangements. One of these arrangements is called small-group teaching. It has been ascertained that a small-group teaching arrangement is more effective than a one-to-one teaching arrangement. In that sense, teaching academic skills to pre-school children in small-group…

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…

A progressive time-delay and a trial-and-error strategy were compared in teaching sight word acquisition to two children with severe behavior disorders. Observational learning was also studied. Results found direct and observed instruction both effective, and progressive time delay somewhat more effective than trial and error. (Author/PB)

Effects of constant time delay in teaching sight word reading to four disabled preschoolers were evaluated. The method was reliably implemented in a group setting, effectively taught all targeted stimuli in near-errorless fashion, promoted observational learning across students, and resulted in greater expressive labeling and receptive…

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)

A progressive time delay procedure used in a small group instructional arrangement was successful in teaching four high school students with severe handicaps to read community-referenced words. Two of the students learned additional words by observing their peers. (Author/DB)

This study compared effects of two variations of the constant-time-delay (CTD) procedure on the observational learning of content area vocabulary by seven primary grade students with learning disabilities in a small group instructional setting. Both conditions (every student writes all words or only target student writes) were equally effective…

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 report summarizes the results of research studies on instructional practices that significantly affect the cognitive, language, or mental abilities of students with disabilities. The investigation reviewed current research on instruction of students with moderate disabilities and sought to identify effective instructional practices. The steps…
