Carbon Nanotube Thermal Interfaces And Related Applications, Stephen L. Hodson

Open Access Dissertations

The development of thermal interface materials (TIMs) is necessitated by the temperature drop across interfacing materials arising from macro and microscopic irregularities of their surfaces that constricts heat through small contact regions as well as mismatches in their thermal properties. Similar to other types of TIMs, CNT TIMs alleviate the thermal resistance across the interface by thermally bridging two materials together with cylindrical, high-aspect ratio, and nominally vertical conducting elements. Within the community of TIM engineers, the vision driving the development of CNT TIMs was born from measurements that revealed impressively high thermal conductivities of individual CNTs. This vision was …

Exploring The Role Of Feedback And Its Impact Within A Digital Badge System From Multiple Perspectives: A Case Study Of Preservice Teachers, Erin D. Besser

Open Access Dissertations

The purpose of this qualitative case study is to examine the role feedback plays within the instructional process, and how students are using feedback to inform their course work within Digital Badge contexts. Educators are looking toward Digital Badges as a way to increase student engagement (Abramovich et al., 2013; Glover & Latif, 2013), develop mastery with critical concepts (Mehta et al., 2013), and reduce gaps in student knowledge (Bowen & Thomas, 2014; Guskey, 2007). Feedback is emphasized as a critical component (Bloom, 1968, 1976; Guskey, 2007; Kluger & DeNisi, 1996; Slavin & Karweit, 1984). Instructors need to be able …

Beliefs About Toddler And Care: A New Measure For Infant Toddler Teachers, Treshawn L Anderson

Open Access Dissertations

The first three years in a child's life are particularly important, as this is a critical time for development in all learning domains, however some of the settings in which infants and toddlers are learning and developing (i.e., child care) have been found to be of despairingly low to mediocre quality, with teacher qualifications also being minimal (Burchinal, Roberts, Nabors, & Bryant, 1996; Howes, Whitebook, & Phillips, 1992; Ruzek, Burchinal, Farkas, & Duncan, 2014; National Survey of Early Care and Education [NSECE] Project Team, 2013, 2014; Vandell & Wolfe, 2000).

The Effects Of A Model-Eliciting Activity On High School Student Design Performance, Tanner J Huffman

Open Access Dissertations

Modeling allows students to become more effective designers. High school technology and engineering students engage in engineering design challenges as part of traditional instructional practices. Model-eliciting activities (MEA) present students with opportunities to elicit mathematically thinking that facilitates modeling. Students (n=266) from four schools completed a model-eliciting activity (MEA) and design challenge procedure. The research design utilized a quasi-experimental method, post-test only, with homogenous matching comparison groups based on possible confounding variables. A rubric was used to measure student design performance. Students in the comparison group (n=124) completed a traditional design challenge and were assessed on their design performance. Students …

English Language Learning Kindergartners' Dynamic Responses To Picturebook Reading, Jiyoung Yi

Open Access Dissertations

This study explores the nature of English language learning by kindergartners as they engage in multimodal literacy practices in response to picturebook readings in a mainstream classroom. Three focal Spanish-speaking kindergartners and their classroom teacher took part in this study. Data were collected daily for four months in a half-day morning kindergarten program. The participants' verbal and nonverbal classroom interactions during picturebook readings were coded and analyzed to characterize the nature of ELL kindergartners' multimodal responses to picturebook readings. Findings indicate that the classroom instruction did not fully address the differences in the focal children's levels of English language proficiency. …

A Sociosemantic Examination Of Secondary English Teacher Written Feedback, Ryan Angus

Open Access Dissertations

The purpose of this study was to provide a functional linguistic based description of teacher writing comments in secondary ELA classrooms. Based within a case study methodology, this study used analytical tools from Systemic Functional Linguistics (SFL) and Legitimation Code Theory (LCT) in order to discover the various meanings that teachers make through their commenting practices. The findings of the study show that teacher comments focus on the content of the student writing, but also, significantly, help teachers to discursively realize various teacher identities. It was also found that teacher comments tended to either be concrete in their reference to …

The Relationship Between Teachers' Perceptions Of The Feedback They Receive And Their Teaching Efficacy In High-Performing Schools, Joshua D. St. John

Open Access Dissertations

As reform efforts are prescribed in every state through mandates and regulations in an effort to better prepare students to compete in a global economy, and as states like Indiana implement new evaluation plans for teachers based on a rigorous rubric and objective measures of student achievement, close attention to the ripple effects must be involved. While efforts such as professional learning communities and instructional coaches are aimed at building teacher capacity, maximum results can only be achieved when school leaders balance how they leverage their evaluative power while promoting these formative experiences. Absent in the drive for heightened accountability, …

Alternative Teacher Certification: Secondary School Principals' Perceptions In Indiana, Jane Corinne Newblom

Open Access Dissertations

As teacher recruitment intensifies to locate qualified teachers for our nation's classrooms, alternative teacher certification programs are becoming prevalent. Initially these programs were designed to attract professionals and college graduates to enter urban classrooms. However, what has occurred is that over 140 alternative certification programs are available to teacher candidates. Some of these programs are well designed with education courses and content area methodology along with pre-service teaching internships while others may not provide the opportunities for new teachers to be successful in their first years of teaching. This study investigated the perceptions of secondary school principals regarding the effectiveness …

Systems Of Accountability As A Technology Of Governmentality: Policy, Preparation, And Inclusive Practice, Denise Lavoie Lafrance

Open Access Dissertations

Neoliberal ideology frames the discourse of the current political rhetoric of education as an economic investment in the preparation of students to compete in a global economy. These discourses that emanate from policymakers shape the construct of schooling and control the trajectory of education in the US. As education policy becomes centralized, accountability systems are assumed to be the driver of positive educational outcomes and higher student achievement; however, the impact of these systems of accountability shape teaching practice and may be pushing students with disabilities out of the competition and violating their right to access and participate in general …

Circles And Lines: Complexities Of Learning In Community, Sara Lynne Schupack

Open Access Dissertations

Following is a study that explores learning in community in a fully-integrated, team taught course at a community college in New England. These classes, Learning Communities (LCs) represent rich opportunities for exploring and practicing democratic education. From a theoretical grounding in social learning theories and an exploration into learning and community as active, ongoing phenomena, I present narrative, relational research as enactment. Data from field notes, interviews, focus groups and researcher reflections inform findings and analysis. I represent this as an experience parallel to -- not claiming either to mirror or replace -- the experiences of the other participants. In …

Racialized Spaces In Teacher Discourse: A Critical Discourse Analysis Of Place-Based Identities In Roche Bois, Mauritius, Elsa Marie Wiehe

Open Access Dissertations

This eleven-month ethnographic study puts critical discourse analysis in dialogue with postmodern conceptualizations of space and place to explore how eight educators talk about space and in the process, produce racialized spaces in Roche Bois, Mauritius. The macro-historical context of racialization of this urban marginalized community informs the discursive analysis of educators' talk at school. Drawing on theories of race that call for the non-deterministic exploration of race relations as they occur in different contexts and times (Hall, 2000; Pandian & Kosek, 2003; Essed & Goldberg, 2000), I explore the spatial racialization of children in Roche Bois as a process …

Production Of Third Spaces For Immigrant English Language Learners: (Re)Negotiating Identity And Discourse In The Secondary Classroom, Andrew W. Habana Hafner

Open Access Dissertations

This study explores theoretical and pedagogical implications of space, language, and power in renegotiating identity for immigrant English Language Learners (ELLs) in secondary schools in the United States. The primary research question explored in the study is: How does spoken and written language and discourse shape the production of third spaces for renegotiating immigrant student identity in the ELL writing classroom? I adopt an epistemological lens of space from a postmodern geographic perspective that contends that space is socially produced and is co-constituted by material, abstract and lived spaces. The theoretical framework draws on constructs of social space, space-time, and …

The Voice Of Elementary School Principals On School Climate, Suzanne Elayne Scallion

Open Access Dissertations

School climate has been described as "the set of internal characteristics that distinguish one school from another and influence the behaviors of each school's members" (Hoy, Smith & Sweetland, 2005). In the landmark study by Brookover, Schneider, Beady, Flood and Wisebaker (1978), school climate was found to be a more significant factor in student achievement than the variables of race and socioeconomic status. Principals need training in the phenomena of school climate and to develop the skills needed to alter it as needed for the benefit of students. This phenomenological study explored the conceptual understanding of school climate by experienced …

The Tactical Games Model Sport Experience: An Examination Of Student Motivation And Game Performance During An Ultimate Frisbee Unit, Eric John Carpenter

Open Access Dissertations

Students benefit from positive sport experiences in physical education. If designed well, sport provides a social avenue for physical activity and strengthens student achievement in psychomotor (e.g., motor skill), cognitive (e.g., decision-making), and affective (e.g., personal and social responsibility) learning domains. Unfortunately, not all students receive quality sport instruction and many students fail to have positive sport experiences in physical education. The Tactical Games Model (TGM, Griffin, Mitchell, & Oslin, 1997) is an instructional model focused on improving student sport experiences. As a constructivist approach to teaching and learning sport, TGM reshapes sport lessons to allow students to experience small-sided …

Data were collected from teacher interviews, teacher questionnaires, classroom and school artifacts, and descriptive field notes from observations. Data were analyzed using content analysis and open, axial, and …

Engaging Students In Mathematics Conversations: Discourse Practices And The Development Of Social And Socialmathematical Norms In Three Novice Teachers' Classrooms, Mary T. Grassetti

Open Access Dissertations

Research on learning to teach mathematics reveals that mathematics teaching is a complex process (Lerman, 2000) and classroom teaching and learning is a “multifaceted, extraordinarily complex phenomenon” (O’Connor, 1998, p. 43). Moreover, research reveals that the mathematics reform agenda has had an impact on what happens in the mathematics classroom, however, the impact has been superficial (Kazemi & Stipek, 2001) with teachers often retaining their pre-reform habits and attitudes in regards to mathematics teaching and learning (O’Connor, 1998). This study examined the reform discourse practices that three novice teachers, who had been enrolled in a reform based methods course during …
