Carbon Nanotube Thermal Interfaces And Related Applications, Stephen L. Hodson
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
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 …
The Relationship Between Teachers' Perceptions Of The Feedback They Receive And Their Teaching Efficacy In High-Performing Schools, Joshua D. St. John
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, …
It's Nothing Personal: Competing Discourses For Girls And Women In Mathematics, Shannon Dawn Bryant
It's Nothing Personal: Competing Discourses For Girls And Women In Mathematics, Shannon Dawn Bryant
Open Access Dissertations
This dissertation used a post-structural feminist theoretical lens to examine women’s under-representation in mathematics graduate programs and careers. Five dominant discourses that potentially influence women’s decision to enter mathematical careers were discussed, including how those discourses interact in competing and complementary ways to shape women’s and men’s ideas about the nature of mathematics. The study investigated the long-term impact of a single-sex reform-based summer mathematics program on high school girls. The study utilized a variety of data collection techniques including surveys, field observations, phenomenological interviews, and artifact collection. Nine participants who were enrolled in a summer mathematics program for high …
