The Use Of The South Carolina School Improvement Model - Quick Cycles In Sixth-Grade Science Classrooms, Jennifer Gnann

All Dissertations

Using data to make informed decisions about instruction strengthens a teacher’s delivery of content within the classroom. However, many teachers have not been taught how to properly use a model of rapid improvement cycles to analyze data and apply it to their classroom instruction. I modified the South Carolina School Improvement Model so that it could be used in short cycles to see how teachers used it to plan for, monitor, and adjust instruction in their classrooms.

I conducted a single case study over a six-week period in which I instructed two sixth-grade science teachers on how to use the …

From Experiences To Beliefs: An Exploratory Case Study On Science Teachers’ Attitudes Towards Emergent Bilinguals, Yamil Ernesto Ruiz

All Dissertations

Emergent bilingual (EB) students in the US are those who are in the process of developing academic English proficiency. EBs are some of the fastest growing populations of students in American public schools. There exists a great deal of research geared towards developing both curricular resources and instructional strategies to best support EBs in the science classroom, however many of these professional development studies lament the lack of growth in terms of achievement in science learning outcomes of EBs. It is possible that due to a lack of transformation in their beliefs that the teachers in these studies do not …

Exploring Transfer Students’ Perceptions Of Their Transition Experience In Calculus 2 At A Research Intensive Institution: A Schlossberg’S And Tinto’S Theory Approach, Steven Edalgo

All Dissertations

This study explored the lived experiences of eleven transfer students as they described their experiences in Calculus 2 at very high research land grant institutions (R1). This qualitative investigation focused on the psychological phenomenon of transition as the transfer students perceived, reflected, made sense, and understood their transition experience. Furthermore, this study explored transfer students’ understanding of how they perceive the attributes of their success or lack of success in Calculus 2.

Employing the use of Schlossberg’s Transition Framework along with Tinto’s Persistence/Departure Framework, the perceptions of the transition experience was analyzed through the lens of this conceptual framework. The …

Use Of Vocabulary Strategies To Aid English Language Learners In A General Education Biology Classroom, Virginia Perry

All Dissertations

The demographics of the typical American classroom continue to present as a more diverse student population with the increase of English Language Learners (ELL) entering public schools. General education teachers on a secondary level are challenged with incorporating academic language instruction into content instruction for ELLs. Many of these teachers seek appropriate instructional strategies to teach ELLs academic language skills related to literacy to comprehend the specific content taught at the secondary level. A deeper understanding of language and skill acquisition within a secondary classroom can help guide future efforts in implementing effective literacy strategies to address ELLs’ academic language …

Using In Vitro, In Silico, And In-Classroom Techniques To Address The Gender Data Gap In Health Care, Kelsey Watts

All Dissertations

Cardiovascular diseases (CVDs) are the leading cause of death worldwide in males (XY) and females (XX). Prior to menopause, females have a relative protection against serious cardiac pathologies compared to age-matched males. This phenomenon is widely attributed to the ovarian hormone estrogen. Unfortunately, hormone replacement therapy to maintain estrogen levels in postmenopausal females has overall adverse effects, and it is not recommended for long-term use or as a preventative measure for eCVDs. A major driver of CVDs, specifically heart failure, is cardiac fibrosis: the continued buildup of scar tissue that reduces the heart’s ability to pump. There are currently no …

An Exploratory Multiple-Case Study Of Nepal’S Science Teacher Educators’ Knowledge And Practices Of Active Learning And Culturally Responsive Teaching, Sunil Pokhrel

All Dissertations

The benefits of implementing active learning (AL) embedded with culturally responsive teaching (CRT) practices are well established: students’ deep learning of science is promoted and the achievement gaps between students of majority and minority backgrounds are reduced. Unfortunately, the acceptance for AL and CRT in Nepal’s science teacher programs is low and implementation is superficial. Using a qualitative multiple-case study, the study examined the understanding of seven Nepali science teacher educators (STE) of AL and CRT practices. The challenges faced by the STEs to implementing these two pedagogies at three of Nepal’s science education-focused Bachelor of Education (B.Ed.) programs were …

Chasing Polys: Interdisciplinary Affinity And Its Connection To Physics Identity, Tyler Scott

All Dissertations

This research is based on two motivations that merge by means of the frameworks of interdisciplinary affinity and physics identity. First, a goal of education is to develop interdisciplinary abilities in students' thinking and work. But an often ignored factor is students interests and beliefs about being interdisciplinary. Thus, this work develops and uses a framework called interdisciplinary affinity. It encompasses students interests in making connections across disciplines and their beliefs about their abilities to make those connections. The second motivation of this research is to better understand how to engage more students with physics. Physics identity describes how a …

The Effects Of A Course On Statistical Literacy Upon Students' Challenges To Statistical Claims Made In The Media, Rose Martinez-Dawson

All Dissertations

Statistical literacy involves critically evaluating and questioning statistics encountered in everyday life. The purpose of this study was to evaluate students' questions (challenges) concerning statistics encountered in everyday life and how these challenges differed before and after taking an undergraduate statistics course, entitled Statistics in Everyday Life 200 (SIEL), which focused on statistical literacy. One hundred forty-four students were given three media articles to indicate questions they had concerning statistics cited in the articles and explain why these questions were important to ask. Students' responses were categorized based on the topic and were assessed using the Statistics Literacy Components Rubric …

Exploring Teacher Perceptions Of Influential Facilitators Of Elementary Mathematics Professional Development: A Mixed Methods Investigation, Sandra Linder

All Dissertations

This dissertation examines the role of the facilitator in elementary mathematics professional development. An exploratory sequential mixed methods design was utilized to answer the central research question: How do United States elementary school teachers perceive an influential facilitator of elementary mathematics professional development (EMPD)? Phase one of this study explored teacher perceptions through a phenomenological design, which informed the second phase of the study, the implementation of a survey instrument to elementary school mathematics teachers on a larger scale. This dissertation is divided into six chapters. Chapter One presents a rationale for examining the role of the facilitator in professional …
