Effects Of A Self-Management Procedure Using Student Feedback On Staff Members' Use Of Praise In An Out-Of-School Time Program, Cade T. Charlton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Out-of-school time (OST) programs are under increasing pressure to improve student achievement. However, OST program administrators face a number of challenges to improving program effectiveness including inconsistent student participation, inexperienced staff members, and a lack of high-quality professional development. OST program administrators can address these challenges by implementing staff development practices that encourage the use of effective instructional strategies.

Specific praise is a simple and effective instructional strategy that has been linked to improved student engagement, enhanced academic achievement, and stronger student-teacher relationships. Unfortunately, there have been very few studies examining the effects of interventions designed to increase OST staff …


Self-Determination Training: A Collaboration Model For Schools And Vocational Rehabilitation, Shannon M. Williams May 2016

Self-Determination Training: A Collaboration Model For Schools And Vocational Rehabilitation, Shannon M. Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Transitioning from high school to postsecondary education and employment is often difficult for students with disabilities. Research has shown that students with increased self-determination skills have a greater likelihood of being successful in a postsecondary setting and in obtaining employment.

Students with disabilities often receive extensive specialized instruction in the areas of English and math, but their teachers have not historically been given training in teaching self-determination. Vocational Rehabilitation counselors are trained to give career guidance and encourage self-determination skills, but are not experienced teachers.

The purpose of this thesis was to determine whether or not a self-determination curriculum created …

An Evaluation Of A Stimulus Preference Assessment Of Ipad Applications For Young Children With Autism, Lyndsay D. Nix

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The process researchers use to determine what children with disabilities like and dislike is called preference assessment. Studies have been conducted with preference assessments using different types of materials (e.g., food, toys, music). In this study, we used a preference assessment on the iPad for children with autism. The purpose was to see if iPad applications (apps) could be used to increase responding. The preference assessment ranked iPad apps for each participant in order of most-preferred to leastpreferred. Participants’ responding increased when they could receive the most-preferred iPad app for completing the task (i.e., stringing beads). These results show that …


The Effects Of Didactic Instruction On The Rate Of Preservice Teachers' Low-And High-Level Questions, Monica Lewis May 2016

The Effects Of Didactic Instruction On The Rate Of Preservice Teachers' Low-And High-Level Questions, Monica Lewis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Evaluation Of Interactive Computerized Training To Teach Paraprofessionals How To Implement Errorless Discrete Trial Instruction, Kristina R. Gerencser May 2016

Evaluation Of Interactive Computerized Training To Teach Paraprofessionals How To Implement Errorless Discrete Trial Instruction, Kristina R. Gerencser

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As special education classrooms continue to rely on paraprofessionals to implement interventions, provide instructions, and monitor student progress— it is imperative paraprofessionals are well trained. Without adequate training, paraprofessionals can unintentionally create prompt dependency, limit academic growth, and reinforce problem behavior. However, providing quality training to paraprofessionals can be costly to school districts. Interactive computerized trainings may be a solution. The current study investigated the effectiveness of an interactive computerized training to teaching paraprofessionals a commonly used teaching strategy for children with Autism Spectrum Disorder and other related developmental disabilities called discrete trial instruction. Often procedures to reduce student errors …


Negative Reinforcement Through Contingent Easy-Task Presentation, Cicely Irene Nickerson May 2015

Negative Reinforcement Through Contingent Easy-Task Presentation, Cicely Irene Nickerson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Escape from instructional demands is one of the most common functions of problem behavior. Some research suggests that a switch from difficult to easy tasks may function as a reinforcer for problem behavior. This is of particular concern for situations in which easy tasks are part of the intervention procedure to reduce problem behavior. This project examined the reinforcing effects of a switch from low-probability (low-p) to high-probability (high-p) tasks for individuals whose problem behavior was maintained by escape from demands. It also provided preliminary evidence as to the quality of reinforcement provided by a switch from low- high-p tasks. …


Teacher- And Student-Developed Summaries Of Performance: Perceptions Of Teachers And Vocational Rehabilitation Counselors, Heidi S. Preece May 2015

Teacher- And Student-Developed Summaries Of Performance: Perceptions Of Teachers And Vocational Rehabilitation Counselors, Heidi S. Preece

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Special education students often struggle to access services upon graduation from high school. A summary of performance is a document that should ease this transition, but often is nothing more than a meaningless piece of paper. This study sought to use a student-completed portfolio as a summary of performance.

A student-completed portfolio and a teacher-completed summary of performance document was evaluated by special education teachers and Vocational Rehabilitation counselors. Results indicate the usefulness of a student-completed portfolio for person centered planning.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the impact of a framework for implementing social skills training, entitled BLISS, on the social vocalizations of students with autism spectrum disorder.

The number of students with autism spectrum disorder is on the rise and many of these students are being served predominantly in general education settings. However, there is a serious lack of social skills training interventions that have been effectively integrated into the typical school setting, including the use of typically available school personnel as interventionists. The developers of the BLISS approach take a step closer to the ideal by integrating brief social skills instruction …


Perceptions Of Customized Employment Among Employers: A Survey And Focus Group, Melanie D. Adams May 2015

Perceptions Of Customized Employment Among Employers: A Survey And Focus Group, Melanie D. Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Employment for individuals with significant disabilities can be achieved through customized employment. Unfortunately the employer perspective of customized employment is often overlooked. This study sought to identify employer's feelings about customized employment.

A focus group developed a list of barriers and facilitators to customized employment. The list was turned into a survey that was given to a different group of employers. The results showed that employers were unfamiliar with customized employment and were most concerned with the cost of accommodations. Researchers found that employers considered support from other agencies, financial incentives and increased productivity to be upsides to customized employment.

Therefore, the purpose of this study was to determine the effects that a targeted, unidirectional tutoring intervention had on the math outcomes for students with learning disabilities in a Secondary Mathematics I class. High school students that had advanced skills in mathematics served as interventionists (i.e., peer tutors) and were trained to deliver the unidirectional …


A Translational Investigation Of Positive And Negative Behavioral Contrast, Megan A. Boyle May 2015

A Translational Investigation Of Positive And Negative Behavioral Contrast, Megan A. Boyle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Applied behavior analysts implement research-based techniques to improve behavior. However, research with nonhumans suggests that intervening to improve behavior in one context may result in a worsening of that same behavior in another context (behavioral contrast). Although there are clinical implications of behavioral contrast, the vast majority of research on contrast has been conducted with nonhuman animals. Results from basic research suggest that contrast is influenced differentially depending on whether a change in conditions follows versus precedes a given context. For example, a child might encounter three contexts each day: home, school, and daycare. An intervention to reduce the child’s …

Assessing Preference For Home Language Or English Praise In English Language Learners With Disabilities, Casey James Clay May 2015

Assessing Preference For Home Language Or English Praise In English Language Learners With Disabilities, Casey James Clay

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Assessing preference for stimuli has been shown to be of value when determining potential rewards for individuals with disabilities. Researchers have found that preference for forms of social interaction can be identified for persons with disabilities. Furthermore, these same social interactions can be used as rewards for these same persons. This study conceptualized different languages as different types of social interactions. Assessing preference for languages may be of use to identify forms of social reinforcement that can be used with English Language Learners (ELLs) with disabilities. Identifying reinforcers may be of value for this population to inform how to structure …

Supporting Students With Psychiatric Disabilities In Postsecondary Education: Important Knowledge, Skills, And Attitudes, Scott I. Kupferman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Students with psychiatric disabilities are the largest subgroup of students with disabilities enrolled in postsecondary education. However, their high enrollment rate does not equate to a high retention rate. Approximately 86 percent of students with psychiatric disabilities withdraw prior to degree completion. As a result, calls for improved disability services in postsecondary education have been plentiful. In an effort to take a step toward answering these calls, the current study began the exploratory process of identifying knowledge, skills, and attitudes that are important for disability service professionals to possess in order to provide beneficial services to students with psychiatric disabilities …

The Development And Exploratory Validation Of The Awareness Of Social Justice For Individuals With Disabilities Scale, Daniel J. Kelsey May 2012

The Development And Exploratory Validation Of The Awareness Of Social Justice For Individuals With Disabilities Scale, Daniel J. Kelsey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Individuals with disabilities (IWDs) continue to experience stigma, prejudice, and discrimination that result in social injustice. Counselors of all specialties and theoretic orientations provide services to IWDs. However, there is little discussion about disability-related social justice in the counseling and psychology literature. Counselors, psychology professionals, rehabilitation counselors, and society as a whole, must first be aware of the social injustices that IWDs experience and the role that society has in maintaining them; otherwise, counselors risk perpetuating these social injustices. However, there are no instruments that measure the awareness of social justice issues as they relate to IWDs. By creating and …

Evaluating The Effects Of Reinforcer Choice And Reinforcer Variation On The Response Rates Of Children With Autism, Alice Ann Keyl Austin May 2011

Evaluating The Effects Of Reinforcer Choice And Reinforcer Variation On The Response Rates Of Children With Autism, Alice Ann Keyl Austin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Motivating individuals with autism can be challenging for clinicians and educators seeking to increase skills or decrease problem behaviors. Even when highly preferred reinforcers have been identified, they tend to lose their effectiveness over time. Over the years, several strategies have been developed to maintain the effectiveness of reinforcers. Reinforcer variation has been demonstrated to attenuate decreases in responding associated with repeated exposure to a single reinforcer. Another strategy that has been used to help maintain responding is allowing an individual a choice among reinforcers. Several researchers have suggested that providing choice among several reinforcers may produce the same effects …
