Doctor of Education / Department of Special Education, Counseling and Student Affairs / James Teagarden / This study investigated the effectiveness of an early literacy program for first grade students classified as at-risk for emotional and behavioral disorders, who were nonresponsive to previous schoolwide interventions, and who performed in the bottom one-third of their class on a standardized reading assessment. This study, which consisted of a multiple-probe across intervention groups experimental design aimed to produce literacy and behavior results previously obtained by other well-known researchers. Results indicated growth in oral reading fluency for all five participants, in nonsense word fluency for four out of the five participants, and a decreased display of total disruptive behaviors for all. Findings reaffirm outcomes obtained in previous investigations; specifically, improved early literacy skills are concomitant with ongoing decreases in disruptive classroom behavior. Limitations are discussed and suggestions for future research are provided.

This study was done to evaluate the simultaneous prompting procedure when teaching math skills during play time to young children with disabilities. The research included 5 students who participated in a special education resource classroom and general education classroom. The researcher used a design similar to a multiple probe design. The study found all participants who began intervention met criterion. The research also found students who participated in maintenance and generalization met criterion during those stages.

Five elementary age students with moderate to severe intellectual disabilities were taught shape identification. A multiple probe design across behaviors, replicated across participants, was used to determine the effectiveness of constant time delay to determine the effectiveness of Constant Time Delay to teach shapes. Nontarget information was included in praise statements. All students met criterion on target information of shape identification. All students increased their ability to identify shape words, spell shape words, tell the number of sides of the shapes when presented and tell the number of angles of shapes presented. Generalization occurred during daily walks through the school and community as well as during the probe sessions.

Several research studies have suggested that individuals with ID are at an increased risk of being a target of victimization (Hughes et al., 2012; Wilson et al.,1992). Therapists, caregivers, primary care providers, and school staff may also undervalue or fail to teach critical safety skills early in childhood or in the adolescent years, which increases risk of victimization in adulthood (Dembo et al., 2018). The purpose of the current study was to evaluate the effectiveness, generalizability, and maintenance of the use of behavior skills training to teach stranger safety skills to young adults with intellectual disabilities. Specifically, a two-step safety response in the presence of a lure from a stranger. Overall, the current study’s results demonstrate that the intervention was effective at teaching this population stranger safety skills. Results of the current study also suggest that the target skill was generalizable across settings and maintained at a 13 week follow up. Furthermore, the intervention was rated high for social validity among most participants. Future studies should continue to explore the effectiveness, generalizability, and maintenance of these results.

Children with limited speech using graphic symbols for communication often express themselves predominantly through single symbols rather than symbol combinations. This study aimed to investigate the effect of an intervention strategy that was incorporated into shared storybook reading on the production of graphic symbol combinations. Three children between the ages of 7;9 (years;months) and 10;8 with limited speech and physical impairments participated in the study. A multiple probe design across behaviours (3 different types of semantic symbol combinations) was used, replicated across the 3 participants. Intervention entailed prompting the production of strategic symbol combinations (generated from a matrix) during shared storybook reading by using a prompting hierarchy. The participants’ production of combinations targeted during intervention as well as their ability to generalize to nontarget combinations from the matrix was monitored using a probe test (picture description task). All 3 participants showed some gains in acquiring the combinations and generalizing to nontarget combinations, as measured by the probe test. While 1 participant showed convincing effects, the other 2 showed lower effects. Lower effects may be partly ascribed to participant characteristics as well as to the discrepancies between the intervention and probe contexts. All participants performed better within the shared storybook reading context. Results suggest that the production of symbol combinations can be facilitated during shared storybook reading and that the matrix strategy promotes generalization to untrained semantic combinations. However, participant gains may not reflect immediately in formal testing situations. / Thesis (PhD)--University of Pretoria, 2012. / Centre for Augmentative and Alternative Communication (CAAC) / unrestricted
