This study investigated how three fifth-grade students' understanding of fraction and decimal magnitude evolved over the course of a five-week teaching experiment. Students participated in teaching and learning sessions focused on developing concepts of fraction and decimal magnitude. The following questions guided this study: (1) How do fifth…

This dissertation investigates the impact of cross-modal binding on word reading skills among English Language Learners (ELLs). Using Baddeley's updated working memory model, which includes the Episodic Buffer, this study examines how the ability to bind visual and phonological information in memory influences the reading development of ELL…

Geometry education is an important aspect of STEM education and career development, but it is often overlooked in K-12 education in the United States. Although there is some research on teaching geometry to students with learning difficulties at the elementary level, there is a lack of research on teaching advanced geometry skills at high school…

Second language learners constitute a significant and expanding portion of the global population and there is a growing demand for tools that facilitate language learning and instruction across various levels and in different countries. The development of large language models (LLMs) has brought about a significant impact on the domains of natural…

Reading difficulties during childhood often continue during adulthood and result in adverse effects (e.g., unemployment, poverty). A common method to teach early literacy skills is via multisensory instructional programs, which use combinations of mnemonic devices, such as visual, auditory, tactile, and kinesthetic movements. The current…

The purpose of this qualitative descriptive study was to explore the perceptions of transition specialists on effective teaching techniques for developing work-readiness and self-determination skills for individuals with intellectual disabilities (ID) participating in a post-secondary transition program. For this study the theoretical framework…

Generalization is the ability to apply regularities to novel instances, for example, correctly guessing that the plural for the novel English word 'wug' should be 'wugs'. Early language learners make overgeneralization errors like 'mouses', applying regularities beyond their attested uses. Theories concerned with the question of how learners learn…

Adults with developmental disabilities may not learn the safety skills needed to maintain the safety of those within their communities. Basic life-saving skills are valued by community members and increase independent and integrated living and employment opportunities. This study used an instructional package consisting of modeling, task analysis,…

In many U.S. states, there is a growing population of academically, culturally, and linguistically diverse English learners enrolling in the public educational system. It is important that collaboration occurs between content area teachers and ESL specialists at the secondary level for supporting and equipping teachers with the skills that they…

For the purpose of this research, a concurrent multiple baseline design was used to measure the effects of a Constant Time Delay (CTD) intervention. CTD was implemented as an intervention to support four transition students' abilities to recognize functional sight words. The sessions were held during a summer transition program on a large…

Students with disabilities benefit from opportunities where skills learned through direct instruction can be practiced and experienced within nontraditional social contexts. Direct instruction methods are important in special education, however one of the challenges with it is that students with disabilities might not gain the understanding to…

The purpose of this exploratory collective case study is to discover how geospatial education can meet the geospatial workforce needs of the Commonwealth of Virginia, in the emerging intelligent web mapping era. Geospatial education uses geographic information systems (GIS) to enable student learning by increasing in-depth spatial analysis and…

Research suggests that high school aged individuals with developmental disabilities are at a higher likelihood of lacking the prosocial behaviors necessary for successful transition into post high school life and a work environment. Decreased vocational success often leads to increased likelihood of mental health issues for individuals with…

Recently, professional learning communities (PLCs) have been advocated as a promising approach in higher education (Eaker & Sells, 2015) for faculty development that can improve student learning outcomes and help students graduate with demonstrable skills, yet the field is still lacking in research on this phenomenon within higher education…

Research examining the relationship between teachers' beliefs and classroom practice has been on the rise. While several researchers (Buehl & Beck, 2015; Fang, 1996; Pajares, 1992) have examined the relationship between teachers' beliefs and practice, there is not one agreed upon conclusion. This dissertation, presented as two studies, seeks…
