In order to examine the statistical significance from pretest to posttest in knowledge of electrophoresis …

A Quantitative Analysis Of Whether Elementary Teachers’ Science Kit Usage And Beliefs Can Predict State Science Assessment Scores, Tony E. Rice

Dissertations

The purpose of this survey was to describe and analyze the perceptions of elementary school teachers’ in a Midwestern state concerning their use of a science kit program, including to what extent a school’s state science assessment scores can be predicated from the level of science kit usage.

Prior research indicates that elementary school teachers lack the confidence in teaching science primarily because of their weak undergraduate training in inquiry-based instruction and the lack of a strong science background. Authors such as Dickerson et al. (2006) and Riggs and Enochs (2006) argued that science kits and the materials included in …

Females In Automotive Careers: Career Decision-Making Influences And Experiences During University Preparation And Beyond, Russell A. Leonard Jr.

Dissertations

Today, women fill nearly 50% of the jobs in the U.S. economy (U.S. Dept. of Labor, 2014). While women are making progress in many careers once considered male only, they are still underrepresented in the male-dominated Science, Technology, Engineering, and Math (STEM) careers, filling only 25% of available STEM jobs (Beede et al., 2011). The problem is not a lack of interest in STEM subjects, but a “leaky pipeline” that develops early in adolescence. By the eighth grade, half as many girls are interested in STEM careers as boys (National Science Foundation [NSF], 2007). Even after graduation from college, women …

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 …

Supplemental Action Learning Workshops: Understanding The Effects Of Independent And Cooperative Workshops On Students’ Knowledge, Kathryn M. Morris

Dissertations

Community colleges enroll more than half of the undergraduate population in the United States, thereby retaining students of varying demographics with extracurricular demands differing from traditional four-year university students. Often in a collegiate lecture course, students are limited in their abilities to absorb and process information presented by their instructors due to content-specific cognitive gaps between the instructor and the student (Preszler, 2009). Research has shown implementation of instructor-facilitated action learning workshops as supplemental instruction may help bridge these cognitive gaps allowing better student conceptualization and dissemination of knowledge (Drake, 2001; Fullilove & Treisman, 1990; Preszler, 2009; Udovick et al., …

The data indicated that administrators believed that 8^th grade student performance …

Assessing The Impact Of Historical Story Telling On Student Learning Of Natural Selection, Janice Marie Fulford

Dissertations

Research suggests that because of its historical nature, the learning of evolutionary biology is problematic compared to that of other science disciplines. While explanations used in historical sciences often employ historical narratives, which are distinct from narratives in other contexts, such as stories, the two types of narratives have structural similarities that suggest the potential role of stories based in the history of science for the teaching of evolutionary biology. Stephen Klassen, a prominent science educator, has studied how stories from the history of physics can promote the learning of and attitudes towards science. Klassen’s pioneering work identifies structural components …

Transformative Models In K-12 Education: The Impact Of A Blended Universal Design For Learning Intervention, Kai Monet Mathews

Dissertations

Accountability measures, by way of standardized curriculum and assessments, have played a large part in the attempt to ensure that students from all backgrounds receive equal access to quality education. However, the inherent disadvantage of a standardized system is the implied assumption that all students come in with the same knowledge, learn at the same pace, and learn the same way. In the wake of an increasingly diverse K-12 population, educational researchers, learning theorists, and practitioners agree that the concept of the average student is, in fact, a myth. Students come to school with different needs, norms, interests, cultural behavior, …

Investigating The Impact Of Reflexive Practices On College Students In A Science Laboratory Course, Chandrani Mishra

Dissertations

Emphasis on professional practices to develop students’ professionalism is currently a major focus of higher education. Studies have shown the benefits of reflexive practices in classroom to facilitate the development of students’ professional attitude or identity in some fields. Reflexive practices involve students in self-reflection where he/she reflects on his/her own actions. Little investigation about the benefits of reflexive practices in the development of students’ scientific identity in a science class led to my investigation. Development of a scientific identity of students and their overall interest and motivation in science is deemed essential for retaining students in STEM fields.

My …

Identities And Motives Of Naturalist Development Program Attendees And Their Relation To Professional Careers, Jennifer A. Mraz

Dissertations

In recent years, there has been much concern over the decline of biologists who actually identify themselves to be naturalists, which negatively impacts the field of conservation and the study of biology as a whole. This could result in a decrease in individuals who participate in naturalist-like activities, such as informal environmental education and environmental volunteerism. The purpose of my study was to determine what discourse identities were held by naturalist development program participants, how these discourse identities related to their volunteer motives in environmental settings, and how discourse identity related to professional careers. I defined identity through the lens …

Investigating How Students Communicate Tree-Thinking, Carrie Jo Boyce

Dissertations

Learning is often an active endeavor that requires students work at building conceptual understandings of complex topics. Personal experiences, ideas, and communication all play large roles in developing knowledge of and understanding complex topics. Sometimes these experiences can promote formation of scientifically inaccurate or incomplete ideas. Representations are tools used to help individuals understand complex topics. In biology, one way that educators help people understand evolutionary histories of organisms is by using representations called phylogenetic trees. In order to understand phylogenetics trees, individuals need to understand the conventions associated with phylogenies.

My dissertation, supported by the Tree-Thinking Representational Competence and …

Secondary Mathematics Teachers’ Attitudes And Beliefs Toward Statistics: Developing An Initial Profile, Christina M. Zumbrun

Dissertations

Over the last several decades, mathematics education researchers have given increased attention to students’ and teachers’ attitudes and beliefs toward mathematics and statistics, but no work has been done that examines practicing secondary mathematics teachers’ (SMTs’) attitudes and beliefs towards statistics in light of the GAISE framework and the Common Core State Standards for Mathematics (CCSSM). This study begins to address this gap in the research by creating the Teacher Attitude and Beliefs toward Statistics Survey (TABSS), a synthesis of items taken from the Survey of Attitudes Toward Statistics (Schau, 2003), the Statistics Course Attitude Scale and newly developed items …

A Study Of Conceptual And Language Issues Surrounding Weight, Weightlessness, And Free Fall: Textbook Analysis, Instructional Design, And Assessment, Rex Taibu

Dissertations

Science education is an interdisciplinary field that has developed from and continues to rely on research in the fields of cognitive science, philosophy, psychology, sociology and history. This clearly reflects that learning and teaching can be studied from multiple perspectives. Despite these wide ranging roots, contemporary science education by and large is not informed by the work of research on linguistics, and in particular, the role of language in mediating conceptual understanding. The term “weight” has multiple meanings in both science and everyday language, and this unfortunately creates inherent difficulties for teaching and learning. The present study addresses a need …

The Relationship Between Students’ Applied Mathematics Skills And Students’ Attitudes Towards Mathematics, Taylor Andrew Kilman

Dissertations

Mathematics is a subject with which many students struggle. It has been noted that students’ attitudes towards mathematics can often affect their performance in related courses. The goal of this research is to explore the relationship between students’ basic applied mathematics skill and students’ attitudes towards mathematics. That is, do students, as they learn how to use mathematics in the real world, tend to develop a more favorable outlook towards mathematics? Or, on the other hand, do the attitudes towards mathematics of students remain unaffected as their ability to use mathematics in the real world increases? The current research seeks …

Moving College Students To A Better Understanding Of Substrate Specificity Of Enzymes Through Utilizing Multimedia Pre-Training And An Interactive Enzyme Model, Mounir R. Saleh

Dissertations

Scientists’ progress in understanding enzyme specificity uncovered a complex natural phenomenon. However, not all of the currently available biology textbooks seem to be up to date on this progress. Students’ understanding of how enzymes work is a core requirement in biochemistry and biology tertiary education. Nevertheless, current pre-college science education does not provide students with enough biochemical background to enable them to understand complex material such as this. To bridge this gap, a multimedia pre-training presentation was prepared to fuel the learner’s prior knowledge with discrete facts necessary to understand the presented concept. This treatment is also known to manage …

Integrating Formative Assessment Into Physics Instruction: The Effect Of Formative Vs. Summative Assessment On Student Physics Learning And Attitudes, Chaiphat Plybour

Dissertations

Of many instructional strategies used to improve teaching and learning in science, formative assessment is potentially one of the most effective. A central feature is timely feedback during learning, giving students the opportunity to benefit and improve while also enabling teachers to adjust instruction to learner needs. By contrast, conventional assessment tends to be mostly summative, assigning point scores, grading and ranking students, and providing extrinsic motivation. For maximum effectiveness in enhancing learning, formative assessment should be designed into instruction from the start rather than being an add-on. This project comprised development, teaching, and research aspects. Two physics topic modules, …

Under-Represented Students' Engagement In Secondary Science Learning: A Non-Equivalent Control Group Design, Joy J. Vann-Hamilton

Dissertations

Problem.

A significant segment of the U.S. population, under-represented students, is under-engaged or disengaged in secondary science education. International and national assessments and various research studies illuminate the problem and/or the disparity between students’ aspirations in science and the means they have to achieve them. To improve engagement and address inequities among these students, more contemporary and/or inclusive pedagogy is recommended. More specifically, multicultural science education has been suggested as a potential strategy for increased equity so that all learners have access to and are readily engaged in quality science education. While multicultural science education emphasizes the integration of students’ …

The Leadership Efficacy Of Graduates Of North Carolina School Of Science And Mathematics: A Mixed-Methods Analysis, Renee Mason Letita

Dissertations

This study examines the leadership efficacy amongst graduates of NCSSM from the classes of 2000–07 as the unit of analysis. How do NCSSM graduates’ perceptions of their leadership efficacy align with research on non-cognitive variables as indicators of academic performance using the unit of analysis as a performance outcome? This study is based on the theoretical construct that non-cognitive psychological (also called motivational) factors are core components of leadership self-efficacy, indicative of NCSSM graduates (who had high academic performance and attained STEM degrees). It holds promise for increasing both student interest and diversity in the race to strengthen the STEM …
