Training teachers and paraprofessionals to detect and record putative antecedents and consequences of problem behavior in the classroom has a number of potential benefits. In this study, we evaluated the outcomes of a computer-based training program consisting of lectures, models, and practice. A total of 39 teachers and paraprofessionals participated. Participants scored videos of teacher-student interactions after completing components of the instruction. The study was designed to evaluate the incremental contribution of instruction focused on (a) single exemplars of antecedents and consequences, (b) multiple exemplars of antecedents and consequences, and (c) simultaneously occurring antecedents and consequences. Training to detect simultaneously occurring events was necessary for the majority of participants to reach high levels of performance. The findings support the efficacy of computer-based training and indicate the necessary and sufficient components of this training.
Sight-word instruction can be a useful supplement to phonics-based methods under some circumstances. Nonetheless, few studies have evaluated the conditions under which pictures may be used successfully to teach sight-word reading. In this study, we extended prior research by examining two potential strategies for reducing the effects of overshadowing when using picture prompts. Five children with developmental disabilities and two typically developing children participated. In the first experiment, the therapist embedded sight words within pictures but gradually faded in the pictures as needed using a least-to-most prompting hierarchy. In the second experiment, the therapist embedded text-to-picture matching within the sight-word reading sessions. Results suggested that these strategies reduced the interference typically observed with picture prompts and enhanced performance during teaching sessions for the majority of participants. Text-to-picture matching also accelerated mastery of the sight words relative to a condition under which the therapist presented text without pictures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
