Investigating The Relationship Between Departmental Support Structures, Self-Efficacy And Intention To Persist: An Examination Of Students' Experience In 19 Physics Graduate Programs Across The United States, Diana Sachmpazidi

Dissertations

Science, Technology, Engineering, and Mathematics (STEM) graduate programs experience consistently high attrition rates. Moreover, persistent disparities exist in racial and gender representation. Women and People of Color are significantly underrepresented and have higher attrition rates than men and white and Asian American students. To date, little work is done to understand graduate student attrition or persistence. There is also a lack of information regarding the causes of demographic disparities in attrition. Most past studies in this context have focused on students' attributes, undergraduate preparation, and mentoring relationships. Moreover, student self-efficacy is a contributing factor for undergraduate student retention. Yet, there …

Impacts Of Cohort Membership On Teacher Candidates In An Alternative Certification Program, Katherine Eaton

Dissertations

Post baccalaureate teacher education programs are an effective way to increase the teaching pool with candidates who are content experts (Beijaard et al. 2004; Brantlinger, A., & Smith, B., 2013; Zeichner, K. M., & Schulte, A. K., 2001; Schultz, K., & Ravitch, S. M. 2013; Humphrey et al., 2008). Many of these programs utilize a cohort model design where students progress through the program together as a group (Maher, M. A. 2005; Jorissen, K. T., 2002; Ross et al., 2006; Mandzuk, D. et al., 2005). In his book, Deep Knowledge (2013), Larkin describes the complex nature of preparing candidates for …

Guided Educational Tourism As Informal Science Education: An Empirical Study, Joseph Martin Lane

Dissertations

The scientific research and education communities have long had the goal of advancing the publics’ understanding of science. Informal science education is a powerful mechanism for shaping human conduct, enhancing quality of life, and advancing the publics’ understandings and values regarding science. Guided educational tours (that present science content) provide visitors with unique opportunities to observe and discuss scientific phenomena in the field. Available empirical research related to learning science from guided educational tours is, at best, limited. Research leading to the development of effective guided educational tours that present and interpret scientific information is of interest to both non-profit …

Evaluating The Use Of The Math Reasoning Inventory For Improvement In Fraction Instruction, Kathy Huffman Boyer

Dissertations

In an attempt to close the mathematic achievement gap between students from the United States and students from other countries, a new national set of standards, the Common Core State Standards for Mathematics, was developed and adopted by the state of Michigan in 2010. These standards emphasize mathematical reasoning and application, rather than the previous emphasis on performing calculations. Unfortunately, teachers generally have had little training in how to assess students’ mathematical reasoning, how to teach mathematical reasoning, or how to provide remediation to those students who show need. The purpose of this study was to see if use of …

Eliciting Elementary School Students’ Informal Inferential Reasoning Through Storytelling, Dustin Owen Smith

Dissertations

One growing area of research on statistical learning is Informal Inferential Reasoning (IIR). Makar and Rubin (2009) describe IIR as having three components: making and evaluating inferential claims, supporting claims explicitly with data, and attending to the inherent uncertainty present in statistical inference-making. This dissertation study was built around developing a method for providing opportunities for elementary school students (Grades K, 2, and 4) to engage with IIR within the context of stories and storytelling through a method called Storytelling-Questioning. After interacting with and discussing two separate stories, it was found that students of each grade level were able to …

Instructional Change In Academic Departments: An Analysis From The Perspective Of Two Environment-Focused Change Strategies, Kathleen M. Quardokus

Dissertations

Numerous reports demand changes in college and university teaching practices. This is especially true for science, technology, engineering and mathematics (STEM) disciplines. STEM stakeholders are concerned about student retention within STEM majors, as well as the lack of sufficient graduates with the knowledge to advance these fields. A common conclusion of these reports is that teaching practices must change. Although these calls for change have occurred for decades, STEM fields have yet to experience widespread change. Thus, there is a need for more effective change strategies. Recently, researchers have suggested that effective change strategies should focus on changing the environments …

Chemistry Graduate Teaching Assistants: A Comparison Of The Classroom Discourse Within Expository And Problem-Based Learning Laboratories, Kelley M. Current

Masters Theses

Graduate Teaching Assistants (GTAs) commonly function as instructors within undergraduate chemistry laboratories. This study sought to explore and describe GTA classroom discourse within two distinct instructional modes, using discourse analysis as the theoretical framework. Theclassroom discourse within a series of verification style labs was comparedto the classroom discourse produced within a set of Problem-Based Learning (PBL) labs. The results suggest three primary findings: (1) the apparent relationship between the instructional mode and form of GTA classroom discourse, (2) the patterns in classroom discourse observed within a given instructional mode repeat, irrespective of content, and (3) the classroom discourse observed within …

Using Case Method To Explicitly Teach Formative Assessment In Preservice Teacher Science Education, Amy Elizabeth Bentz

Dissertations

The process of formative assessment improves student understanding; however, the topic of formative assessment in preservice education has been severely neglected. Since a major goal of teacher education is to create reflective teaching professionals, preservice teachers should be provided an opportunity to critically reflect on the use of formative assessment in the classroom. Case method is an instructional methodology that allows learners to engage in and reflect on real-world situations. Case based pedagogy can play an important role in enhancing preservice teachers’ ability to reflect on teaching and learning by encouraging alternative ways of thinking about assessment.

Although the literature …

A Method For Assessing And Describing The Informal Inferential Reasoning Of Middle School Students, Joshua Michael Goss

Dissertations

Informal Inferential Reasoning (IIR) has emerged in the last decade in the study of statistics education. Developing students’ IIR ability is seen as a way of preparing students for the important topic of Formal Statistical Inference (FSI); however, research is still needed in order to investigate how students transition between informal and formal statistical reasoning. A primary difficulty is that we do not have a way of assessing and describing students’ IIR ability levels. In order to address this, an Assessment of Informal Inferential Reasoning (AIIR) was developed, along with a Structure of Observed Learning Outcomes (SOLO) taxonomy (Biggs & …

An Exploration Of Worldview And Conceptions Of Nature Of Science Among Science Teachers At A Private Christian High School, Kara M. Kits

Dissertations

Both worldview and conceptions of nature of science (NOS) are important components in teaching and learning science. However, few empirical studies have examined the interplay between both of these components for teachers or students. Therefore, this study examines the possible relationship between worldview and conceptions of nature of science for secondary science teachers who currently teach at a Christian school.

Qualitative methodologies developed a rich description of the worldview beliefs and conceptions of NOS for teachers in this study. Eight secondary science teachers employed at a private Christian school participated in the study. A Views of Nature of Science (VNOS) …

The Effects Of An Inquiry-Based Earth Science Course On The Spatial Thinking Of Pre-Service Elementary Teacher Education Students, Kevin Douglas Weakley

Dissertations

This study examined the effectiveness of two geography courses at improving student spatial thinking skills. Spatial thinking is an important cognitive skill in the sciences and everyday life. A taxonomy of spatial thinking was constructed by Gersmehl (2008) in geography education which included core modes assessed in this study: comparison, region, transition, analogy, pattern, and association. Two additional modes related to space over time, change and movement, were also assessed. The central research question in this study is: What are the effects of a pre-service teacher education earth science content course (Geography 1900) that is conceptually designed and inquirybased on …

Analyzing The Effects Of Inquiry-Based Instruction On The Learning Of Atmospheric Science Among Pre-Service Teacher Education Students, Robert James Ruhf

Content proficiencies were tested at the beginning of the semester (the pretest) and again at theend of the semester (the posttest). A sample of students participated in post-test interview sessions designed to examine in depth their knowledge, …

Understanding Photosynthesis And Plant Cellular Respiration As “Nested Systems”: The Characterization Of Pre-Service Teachers’ Conceptions, Mary H. Brown

Dissertations

This dissertation project focused on pre-service elementary teachers' conceptions of the plant processes of photosynthesis and cellular respiration as being connected, occurring at multiple ecological levels, and working within "nested systems." Participants enrolled in a biology course designed for elementary education majors provided their views of the processes through a series of tasks with a peer, a semi-structured interview, and clarified both photosynthesisand plant cellular respiration directly following classroom instruction on the two topics. The instructor of the course was interviewed after a preliminary analysis of the participants' responses. Data were analyzed using the qualitative analysis computer program The Ethnograph …
