Item Using Discourse to Improve the Quality of Student Talk and Historical Argumentative Writing(2024) Otarola, Josue; De La Paz, Susan; Special Education; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Frameworks that connect to the Common Core State Standards for English Language Arts and Literacy in Social Studies, such as the College, Career, and Civic Life (C3) Framework for Social Studies States Standards, highlight the need to engage in inquiry-based instruction (NCSS, 2013). Participation in such inquiry requires students to engage in disciplinary thinking and to articulate that thinking to others, both verbally and in writing. However, such disciplinary thinking does not come natural to students (Wineburg, 1991). Thus, students require instruction in disciplinary thinking to learn its complexities and nuances. Once students can engage in disciplinary thinking, they can communicate it and participate in valuable discourse. Therefore, the current dissertation was conducted to explore how students use discourse to engage in argumentation and historical thinking. Chapter 2 of the dissertation is a research synthesis of studies that use discourse to improve learning outcomes in primary and secondary science and social studies classrooms. The purpose of the synthesis was to determine the impact of argumentative discourse on students’ learning outcomes and to understand the instructional components teachers use when holding discourse. Asterhan & Schwarz’s (2016) Argumentation for Learning (AFL) framework guided the research synthesis and the subsequent multiple-case study. Results indicate that discourse can be improved by using multiple instructional groupings, incorporating explicit instruction, modeling, graphic organizers and technology, and engaging students in deliberation. Chapter 3 offers findings from a multiple-case study that was designed to explore how argumentation inhibitors and enablers moderate dialogue characteristics and learning outcomes and to provide a rich description of discourse in ninth-grade US History classrooms with academically diverse students. More specifically, the study captured how students engaged in argumentative discourse and historical thinking using two different discourse structures. The study used a cross-case analysis (Yin, 2018) to compare the discourse across three cases. Each case included a teacher and four students. The first case occurred in a co-taught class, the second case included the same teacher in an honors class, and the third case included a different teacher in an honors class. The first and second case used a modified structured academic controversy (SAC), while the third case used Johnson and Johnson’s (1988) approach to SAC. The multiple-case study and the research synthesis informed the practitioner manuscript provided in Chapter 4. The manuscript details how teachers can use structure and supports to improve student participation and historical thinking in classroom discourse, especially for students with disabilities (SWD) and other struggling learners. The current dissertation provides several important findings. First, my synthesis indicated that students achieve higher learning outcomes when teachers use multiple instructional groupings, students engage in deliberative discourse, and teachers provide students with explicit instruction, modeling, and graphic organizers. Second, the findings from the multiple-case study offered insight into how students of differing academic abilities engage in argumentative discourse and historical thinking. Students of all academic abilities participated at high levels and engaged in deliberative argumentation, though there were differences in the quality of historical thinking skills. The instructional approach used in the multiple-case study is further expanded in the practitioner manuscript. Areas for future research are discussed in the dissertation.Item Implementing Universal Design to Support Neurodivergent Students in Undergraduate Introductory Computer Science Classes(2024) Kaplitz, Emily Mae; Weintrop, David; Computer Science; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)There has been an increase of both neurodivergent students and enrollment in Computer Science programs in higher education. These increases have brought attention to two separate challenges: neurodivergent college students struggle more compared to their neurotypical peers and many students struggle in introductory computer science courses. This study considers both of these realities by investigating the impact of using Universal Design for Learning (UDL) strategies to revise introductory computer science courses. In doing so, it seeks to understand if and how UDL strategies can support neurodivergent students, along with their neurotypical peers, in succeeding in historically challenging academic contexts. This study focused on three questions: How can universal design for learning principles be implemented into an introductory programming course?, How does updating an introductory programming course to follow the universal design for learning framework affect the experience of students?, and What are the experiences of neurodivergent and neurotypical students after updating an introductory programming course to follow the universal design for learning framework? This study was conducted over three semesters of introductory programming courses. The first semester served as a control for the study where no changes were made to the course. In the following semester, the course's lecture slides were updated to be more accessible following Universal Design for Learning principles. In the third and final semester, the course’s lecture slides were updated to be more accessible, and supplementary slides were created for the projects to help students understand what is being asked of them. To assess the interventions, student surveys, interviews, and grades were analyzed. The findings serve as a demonstration of how to modify lecture slides and create programming project slides to apply universal design for learning principles and show the students had considerably better experiences and greater academic success in the course that applied universal design for learning principles. These benefits were recorded for both neurodivergent and neurotypical students, showing that universal design for learning principles benefits all students. The implications of these findings are considered and recommendations for improving introductory programming instruction are discussed. This work advances our understanding of how to help students comprehend foundational computer science concepts and develop the necessary computer science practices to excel in the field.Item Problems and Possibilities: The identities and challenges of early career science teachers(2024) Mesiner, Jennifer Elizabeth; Levin, Daniel M; Elby, Andrew; Education Policy, and Leadership; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Learning to teach is multifaceted and dynamic resulting in a turbulent, fast-changing era of professional life for early career science teachers (ECSTs). Teaching practice is uncertain and tensions are endemic to the profession (Ball, 1993). This dissertation connects to and extends current research of the challenges ECSTs face and how those challenges affect ECSTs’ work, identity, and experience. In the first chapter, I introduce my research focus and offer a personal narrative to provide context of my positionality and experiences between myself and my research. In Chapter 2, I offer a systematic review of the literature to provide a contemporary update to Davis and colleagues’ (2006) review Challenges New Science Teachers Face to answer the question: What challenges do ECSTs face while navigating their first years of teaching? Chapter 3 describes the research design, data sources, and general analysis for the longitudinal case study of an ECST, Alexa. The remaining body chapters build upon Chapter 2 and each other in answer to my remaining research questions: What challenges does Alexa face as an ECST? How does Alexa’s teacher role identity develop over time? In what ways do challenges shape Alexa’s teacher role identity? Chapter 4 builds upon the themes drawn from Chapter 2’s systematic review to explore the challenges Alexa experiences. Chapter 5 describes how Alexa’s identity develops across her early years as an ECST using a Dynamic Systems of Role Identity framework (Kaplan & Garner, 2018). Chapter 6 explores how those challenges impacted Alexa’s science teacher identity using a productive friction framework (Hagel & Brown, 2005a). In Chapter 7, I close by summarizing the research, describing its implications, and offering future directions for research and practice.Item Trends in the Educational Differences in U.S. Mothers’ Paid Work and Child Care Time-Use and Implications for Mothers’ Well-Being(2024) Gao, Ge; Cohen, Philip N; Sociology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation explores U.S. mothers’ time allocation to employment and child care post-2000 and its implications for their well-being, addressing three empirical questions: (1) How have educational disparities in mothers’ developmentally adaptive child care time evolved in recent decades? (2) How have paid work-child care time divisions shifted differently for less-educated versus more-educated mothers? (3) What are the trends in educational disparities in mothers’ well-being, and to what extent do mothers’ time-use patterns contribute to these changes? This dissertation found that there has been a significant historical decline in educational disparities in mothers’ developmentally adaptive child care time investment over the past two decades. Second, mothers with different educational attainments have gradually adopted divergent paid work-child care time coordination strategies: while high school and less educated mothers saw an increased tendency to spend high volumes of time on child care without employment, college-educated mothers became more likely to invest moderate time on child care while maintaining full-time professional jobs. Finally, college-educated mothers, who were initially at a disadvantage, have experienced significant improvements in the quantity and quality of downtime over the past two decades. Some evidence suggests that the shifting distribution of paid work-child care time coordination patterns contribute to the enhancements in leisure quality for college-educated mothers. This dissertation offers an updated understanding of how US mothers with varying educational backgrounds balance work and family, the potential trade-offs between mothers’ well-being and children’s development, with suggestive impacts on the intergenerational transmission of advantage.Item SUPPORTING EQUITABLE CLIMATE CHANGE DECISIONS IN A RURAL COMMUNITY THROUGH EXPANDED NOTIONS OF CLIMATE DATA: USING CRITICAL DATA PERSPECTIVES AND PRACTICES TO SUPPORT CLIMATE LEARNING WHILE CO-DESIGNING AN ONLINE, MAP-BASED, EDUCATIONAL RESOURCE(2024) Killen, Heather Ann; Clegg, Tamara; Education Policy, and Leadership; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Climate change threats are ever increasing, forcing communities to ask: what do they value and how are they going to protect it? Community-based climate education should play a central role in supporting equitable local decisions regarding local responses to climate challenges. However, there is little research about how to best support communities, especially rural communities that may be skeptical of climate change, to see how climate change is affecting their landscapes. In my dissertation I explore a community-based effort to build a map representing a valued local landscape feature and how this effort can act to convene knowledge about local landscape and climate, ratify that knowledge through inclusion onto a map, and ultimately inform community decision making. Guided by the perspectives and practices of critical data science and storylistening I frame my research around data and story. Prior work has considered the role of climate data within environmental education and story within community scholarship, but there is still a need to explore expanded notions of data within community learning and the role of community-held stories in local decision making. My dissertation focuses on how local, personally held landscape and climate data might complement and extend local, institutionally held data and how map building might support data-rich storytelling and listening. Working within a conservative-leaning, rural community and using the ArcGIS StoryMap web application, I engaged six community members over six design sessions to collaboratively design an online, public map of a creek and associated nature trail at the center of their town. I find that participants engaged in six key map-building design processes as they interacted with their local landscape in new ways. I also find that participants used the knowledge they brought into the design space to collaboratively expand, challenge, and occasionally transform their shared understanding. Together these processes allowed local, often generationally held, climate and landscape knowledge to become community-held understanding that could be included as data within the map. Using this analysis, I present my Evidentiary Landscape Learning (ELL) framework, placing my insights into a community-based learning context. The ELL framework demonstrates a pathway for engaging community members to understand how local and beyond-local socio-cultural values and systems are physically embodied in their local landscapes.Item UNDERSTANDING HOW AFRICAN AMERICAN ENGLISH-SPEAKING CHILDREN USE INFLECTIONAL VERB MORPHOLOGY IN SENTENCE PROCESSING AND WORD LEARNING(2024) Byrd, Arynn S; Edwards, Jan; Huang, Yi Ting; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This research examined how linguistic differences between African American English (AAE) and Mainstream American English (MAE) impact how children process sentences and learn new information. The central hypothesis of this dissertation is that these linguistic differences adversely impact how AAE-speaking children use contrastive inflectional verb morphology (e.g., was/were, third person singular -s) to process and comprehend MAE sentences, as well as to infer word meanings when they depend on dialect-specific parsing of sentence cues. To test this hypothesis, this dissertation conducted three experiments on how linguistic mismatch impacts spoken language comprehension and word learning in school-age MAE- and AAE-speaking children. The first study examined how children used the auxiliary verbs was or were to comprehend MAE sentences in an offline spoken language comprehension task. In contrast, the second study asked the same question in an online sentence processing task. The final study examined how children used inflectional verb morphology (i.e., third-person singular -s, was/were) to infer information about novel verbs. Each study examined how participants’ dialect, either MAE or AAE, predicted performance on listening tasks produced in MAE. Furthermore, each study examined how individual differences such as age, dialect density, and vocabulary size influenced children’s performance.Across all studies, results demonstrated that when there were redundant linguistic cues that were not impacted by dialect differences, AAE- and MAE-speaking children used available linguistic cues to process and comprehend spoken language and infer verb meanings in a similar manner. However, when linguistic redundancy was decreased due to perceptual ambiguity, there were group differences in how AAE- and MAE-speaking children used inflectional verb morphology on spoken language tasks. The second study showed that AAE-speaking children were sensitive to contrastive verb morphology in real-time processing, but they were less likely than their MAE-speaking peers to use it as an informative cue to revise initial parses when processing spoken language. The results of the final study indicated that individual characteristics such as age and dialect density influence how dialect impacts a learning process. These results demonstrate that linguistic mismatch can affect spoken language processes. Furthermore, the findings from this research highlight a complex relationship between the effects of linguistic mismatch and individual differences such as age and dialect density.Item “THIS WILL NOT KILL US:” A REFLECTIVE EXPLORATION OF HOW BLACK WOMEN DOCTORAL STUDENTS AND ALUMNAE STRIVED FOR HOLISTIC MENTAL HEALTH AND WELLNESS(2024) Stone, Joakina; Kelly, Bridget T; Counseling and Personnel Services; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The purpose of this qualitative research study was to develop a better understanding of the factors that influenced the holistic mental health and wellness of Black women doctoral students and recent alumnae during their doctoral journey. Although research is emerging on the wellness of graduate students, there is limited literature on Black women doctoral students’ wellness. From 2020 to 2023 there were national events involving Black women that underscored the necessity to understand and prioritize the holistic wellness of Black women doctoral students (e.g. Black women in higher education leaving their high-ranking positions and Naomi Osaka and Simone Biles taking a break from their respective sports and citing mental health as a factor). Using narrative inquiry as a methodological approach, and a conceptual framework comprised of Black feminist thought (Collins, 1986, 1989) and Hettler’s (1980, 1984) six dimensions of wellness, the experiences of nine Black women doctoral students and recent alumnae (who were no more than six-months post-graduation) were explored. This research sought to understand the strategies Black women doctoral students and recent alumnae used to manage and maintain their holistic mental health and wellness. The specific research questions that guided this study are: (1) How do Black women doctoral students and recent alumnae at Research 1 (R1) or Research 2 (R2) institutions in the mid-Atlantic region describe their mental health and wellness while pursuing their doctoral degree? (2) What contributed to and interfered with the holistic mental health and wellness of Black women doctoral students and recent alumnae during their doctoral programs?Co-narrators (participants of the study) participated in two semi-structured interviews, each ranging from 60 to 90 minutes in length. Data collection also included co-narrators submitting memes or gifs that represented their mental health and wellness during their doctoral journey. There were several themes that emerged from the data. First, the visual data revealed that co-narrators experienced exhaustion, anguish, fluctuation between joy and stress, and the need to keep moving forward despite what was happening around them. The images submitted served as a visual representation for the overall experiences of the women in the study and enhanced the understanding of the factors that contributed to or interfered with the holistic mental health and wellness of Black women doctoral students (i.e., Research Question 2). The additional findings that emerged from study are as follows: (a) “Wellness for Your Whole Body:” Co-Narrators Definitions of Holistic Mental Health and Wellness; (b) Factors that Contributed to Holistic Wellness, including the subthemes “They Needed the Sisterhood:” The Importance of Community with Other Black Women, and “Finding Those Pockets:” Intentionally Choosing Wellness in the PhD Journey; (c) Positive and Negative Contributing Factors to Holistic Mental Health and Wellness, which included the subthemes “All Skin Folk Ain’t Kinfolk:” Interactions with Challenging Black Faculty and Administrators, and “My Advisor . . . Was Super Supportive:” How Relationships with Black Faculty and Non-Black Faculty and Administrators of Color Can Influence Wellness; (e) Detractors From Holistic Mental Health and Wellness, which included the subthemes “The PhD Program Is Good About . . .Letting You Know You Don’t Belong:” Impostorism and Lack of Belonging in the Academy and “What Is the Benefit of . . . Being Productive, If You’re Literally Killing Yourself?”: Negotiating Wellness to Finish the PhD. The study concluded with implications for practice and research, followed by a letter from the author directly addressing Black women doctoral students.Item PRIORITIZING NEW TEACHER RETENTION FOR PRINCIPALS IN HARD TO STAFF DIVERSE SCHOOLS(2024) Lane-Pettway, Kimberly; Eubanks, Segun; Education Policy, and Leadership; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Teacher attrition is a major challenge for public school districts across the country, especially in poor, urban and/or high needs schools. Sixty-one percent of school district superintendents identified teacher retention as a top concern. The majority of the teachers who leave are the new, well-prepared, successful teachers and the mid-career teachers. The study design used a mixed methods approach, with an improvement science methodology and an action research design to explore the principal’s role in the retention of non-tenured effective teachers. The design incorporated a focus group, implementing a teacher retention change strategy/change idea, and a survey to assess the potential influence of the teacher retention change strategy/change idea. The research was conducted in three phases. Phase 1 consisted of a qualitative focus group and brief training. Phase 2 consisted of a qualitative and quantitative implementation of a Plan-Do-Study-Act (PDSA) cycle and the completion of a PDSA instrument. Phase 3 consisted of a quantitative survey. The findings supported that principals do consider the retention of effective teachers to be important, however they are not implementing effective strategies. Findings highlighted that when principals implement specific, research-based retention strategies it can enhance the focus on retaining effective teachers; and it shows promise that it may help to retain new teachers. Two recommendations of this study include identifying new and innovative teacher retention strategies and providing principals with targeted training opportunities in order to enhance collaboration and retention strategy implementation at the school level.Item "I'm a dual language teacher": Examining Teachers' Identities in Dual Language Bilingual Education(2024) Cataneo, Amanda; Martin-Beltran, Melinda; Education Policy, and Leadership; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Dual language bilingual education (DLBE) seeks to promote the goals of bilingualism and biliteracy, academic achievement, and sociocultural competence, upon a foundation of critical consciousness (Howard et al., 2018; Palmer et al., 2019). Due to the unique blending of content and language instruction (Cammarata & Tedick, 2012) in these programs, DLBE teachers need specialized skills and knowledge to effectively meet the goals of the program. However, research has found that teachers in DLBE programs lack DLBE-specific training (Amanti, 2019; Cammarata & Tedick, 2012; Freeman et al., 2005; Freire & Valdez, 2017; Lachance, 2017a, Lachance, 2017b) and instead have backgrounds of mainstream or content teaching (de Jong & Barko-Alva, 2015) which would not otherwise prepare them to teach language learners. For DLBE programs to meet their goals to be equitable for MLs, qualified teachers are needed. This dissertation study examines how teachers DLBE conceptualize their identity as language teachers within their DLBE programs, the factors that contribute to a language teacher identity, and the subsequent effect that their identity has on instruction. This qualitative, multiple case study (Yin, 2018) examines the teacher identities and pedagogies of eight DLBE teachers in two different schools and districts. Drawing on language teacher identity and professional learning frameworks, I developed a framework to guide my investigation of DLBE teacher identity (Bunch, 2013; Cammarata & Tedick, 2012; Lave & Wenger, 1991; Martin & Strom, 2016; Yazan, 2018). Data collection included interviews with focus teachers and observations of classroom and collaborative planning meetings, triangulated with interviews with two school administrators. Findings reveal that DLBE teachers’ professional identity acknowledges the distinct focus on language in DLBE contexts and displays nuanced levels of understanding of DLBE goals, especially about the roles of language and sociocultural competence in teaching. Findings also reveal the complex intersection of factors that contribute to the formation of a DLBE teacher identity, including teacher backgrounds, contextual influences of the program, and teacher beliefs. I discuss implications for research and teacher education in understanding and developing professional identity among current and future DLBE teachers.Item TEACHER RETENTION AS A PREDICTOR OF STUDENT PERCEPTIONS OF SCHOOL CLIMATE(2024) Miller, Julie Elizabeth; Brantlinger, Andrew; Education Policy, and Leadership; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation examines the relationship between teacher retention and student perceptions of school climate in an urban school district, both in individual school years and across multiple school years. This secondary analysis uses a school-level measure of teacher retention from New York City (NYC) public schools and measures of school climate constructed from the student version of the NYC School Surveys for 2014-2015 through 2018-2019. Specifically, I constructed an overall measure of school climate that was a school-level, unweighted mean and I used exploratory factor analysis which resulted in three factors (Teacher Support, Classroom Behavior, and School Safety). Using linear regression for individual school years, I found teacher retention rates collected in the fall were a significant, positive predictor of school-wide averages of student school climate survey scores collected in the spring. Using a fixed effects regression model of repeated measures I also found a significant, positive relationship between teacher retention and student perceptions of school climate over the five-year period. Teacher retention was a significant positive predictor of the Teacher Support factor in the fixed effects regression of repeated measures for 2015-2016 through 2018-2019 and also in three of the five individual school years. Teacher retention had a significant, positive relationship with the Classroom Behavior factor in each individual school year but was not significantly related in the multi-year model. Teacher retention was not significantly related to the School Safety factor in any individual school year nor in the multi-year model.
