Although decades of research attest to the importance of vocabulary teaching and learning, and recent research points to principles of effective vocabulary instruction, the small number of studies on actual classroom practice suggest that teachers continue to use the least effective approaches, often focusing on memorization of definitions.…

The purpose of this qualitative inquiry was to explore the implementation of the third pillar of dual language education (DLE), sociocultural competence. Teachers' perceptions of the structures both supporting and challenging implementation of the pillar were examined. An Elementary (K-5) two-way immersion DLE Program in the lower Hudson Valley…

This study explores elementary school teachers' perceptions of emotional intelligence (EI) influence on the academic development of African American elementary students within a charter school in North Carolina. Persistent academic disparities faced by Black students, exacerbated by systemic educational inequalities and socio-cultural challenges,…

Science museums conduct presentations for their audiences to attract and educate visitors, yet research on presentations has primarily concentrated on whether individual presentations were effective. This mixed-methods, quasi-experimental study looks at how the presenter's mental and physical engagements within a presentation affects audience…

The dominant image of mathematics as an abstract, universal, disinterested, and pure body of knowledge both misrepresents disciplinary practice and alienates many students. Undergraduate proof-based courses such as real analysis, which are supposed to introduce students to contemporary academic mathematics, often contribute to such idealized…

Teachers must meet a variety of students' mathematics learning needs but are often not trained to do so. Little is known about how teachers perceive their efficacy to meet diverse math learning needs. The purpose of this qualitative collective case study was to explore teacher attitudes and perceptions of professional development (PD) and…

While the second language (L2) teacher cognition literature has extensively documented what language teachers think, know, believe, and do (cf. Borg, 2006), far less is known about the dynamics of L2 teacher development arising from engagement with L2 teacher education pedagogies. Addressing this problem, Kubanyiova and Feryok (2015) contend that…

The purpose of this qualitative descriptive designed study was to explore how special education teachers from a private special education school with self-contained classrooms describe their experiences teaching and how they identify and select instructional strategies based on student's individual instructional and cognitive needs when teaching…

This dissertation is primarily concerned with nature-human relations -- how human people relate with and see themselves in relation to the rest of nature. Nature-human relations are part of how we make sense of the world around us, and these relationships therefore affect our broader reasoning and decision-making. The magnitude of environmental…

The purpose of this qualitative case study was to explore how teacher perceptions describe the effectiveness and the barriers to implementing Universal Design Learning tools in a proficiency-based system. The problem was that students with disabilities experience achievement gaps in the areas of reading, writing, and mathematics in some classes…

The improvement of music teacher education programs is inevitably tied to improvement of the quality of music instruction in schools. As such, one of the essential avenues for improving educational programs is conducting regular program evaluations. Given the ever-evolving national standards for school music, along with the changing socio-cultural…

Although pronunciation instruction (PI) has started to gain prominence in second language teacher professional development (PD) research (e.g. Nguyen & Newton, 2021), relatively less attention has been given to PD programs in an online format. Adopting a Sociocultural Theoretical (SCT) perspective, this dissertation explored the role of an…

Students with emotional and behavioral disorders are at risk for academic failure in general education-inclusive classrooms. The problem addressed in this study was that some students with emotional and behavioral disorders are not academically progressing in middle school-inclusive classrooms. This qualitative single case study aimed to explore…

Chemistry graduate teaching assistants (GTAs) play a unique but important role in undergraduate STEM education. As leaders of laboratory and discussion sections, GTAs teach fundamental experimental techniques and reinforce course content in classrooms and have more opportunities to interact with students one-on-one or in small groups. GTAs often…

Differentiated instruction (DI) is an effective approach to maximize students' academic success in diverse elementary classrooms. But a current concern in educational research is an insufficient understanding of how novice elementary teachers perceive and apply DI to support student success, especially as student diversity continues to increase,…
