Strengthening Stem Performance And Persistence : Influence Of Undergraduate Teaching Assistants On Entry-Level Stem Students., Stephanie B. Philipp Aug 2013

Strengthening Stem Performance And Persistence : Influence Of Undergraduate Teaching Assistants On Entry-Level Stem Students., Stephanie B. Philipp

Electronic Theses and Dissertations

Increasing retention of students in science, technology, engineering, or mathematics (STEM) programs of study is a priority for many colleges and universities. This study examines an undergraduate teaching assistant (UTA) program implemented in a general chemistry course for STEM majors to provide peer learning assistance to entry-level students. This study measured the content knowledge growth of UTAs compared to traditional graduate teaching assistants (GTAs) over the semester, and described the development of peer learning assistance skills of the UTAs as an outcome of semester-long training and support from both science education and STEM faculty. Impact of the UTA program on …


Satisfying Stem Education Using The Arduino Microprocessor In C Programming, Brandyn Moore Hoffer Aug 2012

Satisfying Stem Education Using The Arduino Microprocessor In C Programming, Brandyn Moore Hoffer

Electronic Theses and Dissertations

There exists a need to promote better Science Technology Engineering and Math (STEM) education at the high school level. To satisfy this need a series of hands-on laboratory assignments were created to be accompanied by 2 educational trainers that contain various electronic components. This project provides an interdisciplinary, hands-on approach to teaching C programming that meets several standards defined by the Tennessee Board of Education. Together the trainers and lab assignments also introduce key concepts in math and science while allowing students hands-on experience with various electronic components. This will allow students to mimic real world applications of using the …


How Do Stem Minority Faculty Members Describe Their Experiences Of Graduate Student And Faculty Socialization?, Ayana Milele Johnson Jan 2012

How Do Stem Minority Faculty Members Describe Their Experiences Of Graduate Student And Faculty Socialization?, Ayana Milele Johnson

Electronic Theses and Dissertations

To remain globally competitive in science, technology, engineering, and mathematics (STEM), we must increase our number of underrepresented minority scientists (URMs) as our country's population becomes more diverse. For URMs to move up the educational and professional ranks, they need to be properly socialized as graduate students and faculty members (Tierney & Rhoads, 1994; Weidman, Twale, & Stein, 2001). Programs such as the Alliance of Graduate Education in Mississippi (AGEM) are designed to assist in the socialization process of doctoral students and, in turn, increase the numbers of the URMs in faculty roles. Therefore, the purpose of this study was …


Gender Differences In Career Satisfaction Among Postsecondary Faculty In Stem Disciplines, Cynthia L. Martin Apr 2011

Gender Differences In Career Satisfaction Among Postsecondary Faculty In Stem Disciplines, Cynthia L. Martin

Electronic Theses and Dissertations

While years of effort to attract more women into higher education careers in science, technology, engineering, and mathematics (collectively known as STEM disciplines) has shown some success, retaining women faculty once they are hired has been much less successful. Their retention is essential in order to maintain diversity among faculty. Understanding the complex factors affecting faculty career satisfaction and, ultimately, their retention at a particular institution and in higher education is needed to guide policies and practices as academic instituions strive to retain highly qualified professors and maintain diversity at all ranks. This study explored salient factors related to faculty …


Psychological Sense Of Community And Retention: Rethinking The First-Year Experience Of Students In Stem, Melissa Dagley Falls Jan 2009

Psychological Sense Of Community And Retention: Rethinking The First-Year Experience Of Students In Stem, Melissa Dagley Falls

Electronic Theses and Dissertations

This investigation looks at the relationship between a STEM learning community's co-curricular activities and students' perceived sense of community (SOC)to determine which activities most influence SOC and, in turn, retention. This investigation shows that SOC can be impacted by a multitude of factors found within the college environment. The most influential of these factors are open acceptance, student academic support services, and residential experiences. Most importantly there were significant differences for African American students participating in the STEM learning community on the measures of SOC, retention, and being on-track in mathematics. Additional data suggested higher levels of being on-track in …


Quantitative High-Angle Annular Dark Field Scanning Transmission To Electron Microscopy For Materials Science, Rumyana Petrova Jan 2006

Quantitative High-Angle Annular Dark Field Scanning Transmission To Electron Microscopy For Materials Science, Rumyana Petrova

Electronic Theses and Dissertations

Scanning transmission electron microscopy (STEM) has been widely used for characterization of materials; to identify micro- and nano-structures within a sample and to analyze crystal and defect structures. High-angle annular dark field (HAADF) STEM imaging using atomic number (Z) contrast has proven capable of resolving atomic structures with better than 2 A lateral resolution. In this work, the HAADF STEM imaging mode is used in combination with multislice simulations. This combination is applied to the investigation of the temperature dependence of the intensity collected by the HAADF detector in silicon, and to convergent beam electron diffraction (CBED) to measure the …
