Constant time delay (CTD) and simultaneous prompting (SP) are effective response prompting procedures for teaching students with moderate to severe disabilities. The purpose of this study was to compare the efficiency of CTD and SP when teaching functional sight words to four students, 8-11 years of age, with moderate intellectual disability (ID)…

The effects of SMART Board technology, an interactive electronic whiteboard, and a 3s constant time delay (CTD) procedure was evaluated for teaching sight word reading to students with moderate intellectual disabilties within a small group arrangment. A multiple probe design across three word sets and replicated with three students was used to…

This study compared the effectiveness of SMART Board, interactive whiteboard technology and traditional flash cards in teaching reading in a small-group instructional arrangement. Three students with moderate intellectual disabilities were taught to read grocery store aisle marker words under each condition. Observational learning (students…

Primary-aged students (N=5) with moderate mental retardation were taught to read environmental sight words and assessed for observational cross-learning of other students' words. Results indicate that the constant time delay method was effective in teaching sight words to four students and all students acquired some information targeted for other…

The study, with four mildly retarded primary-age students, found that constant time delay was an effective instructional strategy when students were taught to read sight words and that incidental learning also occurred as each student acquired some nontargeted spelling information. (Author/DB)

This final report of the Group Errorless Teaching Strategies Research Project is organized by the project objectives and covers planned and actual activities and outcomes. Objective 1 involved a review of the literature related to teaching students with mild and moderate mental handicaps in group settings and resulted in three articles which…
