An Investigation Of Students' Use And Understanding Of Evaluation Strategies, Abolaji R. Akinyemi

Electronic Theses and Dissertations

One expected outcome of physics instruction is that students develop quantitative reasoning skills, including evaluation of problem solutions. To investigate students’ use of evaluation strategies, we developed and administered tasks prompting students to check the validity of a given expression. We collected written (N>673) and interview (N=31) data at the introductory, sophomore, and junior levels. Tasks were administered in three different physics contexts: the velocity of a block at the bottom of an incline with friction, the electric field due to three point charges of equal magnitude, and the final velocities of two masses in an elastic collision. Responses …

A Multiplicity Of Journeys: Stem Education Ecosystems As Sources Of Cultural Sustenance, Christopher Louis Beauprey Cardiel

Dissertations and Theses

In this document, I outline the context and significance of a research problem faced by both formal and informal science, technology, engineering, and math (STEM) educators in the Portland metro area--specifically, the need for greater understanding of the individual and cultural motivations, needs, and agentic behavior of learners, as well as the ways in which these factors intersect with learners' experiences of cultural sustenance within their holistic STEM education ecosystems. I base the significance of this problem on the racial and gender inequities evident in the STEM fields and the social and cultural dynamics that discourage members of these groups …

Experiences Of Undergraduates And Graduate Teaching Assistants In Biology Course-Based Undergraduate Research Experiences, Emma Crystal Goodwin

Dissertations and Theses

Evidence of positive student outcomes from course-based undergraduate research experiences (CUREs) has sparked implementation of CUREs in introductory biology laboratory courses, as one approach to boosting student engagement in research. In a CURE, students collaborate with other students and instructors on a research project, where they conduct novel scientific research that has relevance to a local or scientific community. However, previous research rarely considers that graduate teaching assistants (GTAs) often teach introductory labs. The classroom role of GTAs expands in a CURE--they no longer need to simply teach a lab class, but also to serve as research mentors. GTAs, who …

Investigating The Attitudes, Beliefs And Practices Of High School Chemistry Teachers Regarding The Differentiation Of Instruction, Anna Tyrina

Differentiation of instruction (DI) is a broad term used for a group of pedagogical tools that teachers use to individualize instruction for students of different abilities and needs. Differentiation of instruction is a practice that has been researched and characterized to have a variety of instructional benefits, some of which include increased student motivation and engagement (Tomlinson, 2001). This study sought to characterize the attitudes, beliefs, and practices of ten high school chemistry teachers in Maine regarding the differentiation of instruction. Through a phenomenological approach, interviews with these teachers were analyzed to understand how high school chemistry teachers define differentiated …

Parent Involvement And Student Achievement: Effects Of Indirect Parent Involvement On Student Achievement In Mathematics, Sarah Ann Myers

Electronic Theses, Projects, and Dissertations

Parents are often seen through a deficit lens despite all that they do for their children. Parents want to do all they can to help their children be successful in school and in math specifically. This can be challenging due to the increasing pressure for students to perform well in math, the current methods for teaching math, and the math work students bring home. This quantitative study investigates how home-based parent involvement strategies predict student's math grade point average (GPA). The data in this study was derived from 23,503 participants within the High School Longitudinal Study of 2009 (HSLS:09). With …

Quality Assessment Of Composite Manufacturing Using Automated Visual Inspection System With Sem Images, Md Fashiar Rahman

Open Access Theses & Dissertations

The morphology of fibers (e.g., spatial uniformity, orientation, and length) plays a decisive role in determining the material properties or fabrication quality of fiber-reinforced nanocomposites. Hence, determining the morphology becomes a very critical issue in the field of nanocomposite quality control. The conventional way of quality inspection is to take the scanning electron microscopic (SEM) images of the cross-section of composite material and do the visual checking of these SEM images to evaluate the nanofiber alignment and length distribution. But this type of inspection is often subjective, inaccurate and time consuming. Moreover, the extremely small size of nanofibers makes the …

American Indian Culture And Secondary Science Curricula: Examining The Confluence Of Native Epistemologies And U.S. Public Education Science Standards, Molly Anne Wolk

Theses and Dissertations

Innate to the traditional science curricula taught under the auspices of United States public education are a Neoliberal axiology and Eurocentric epistemology (Howard & Kern, 2019) that do not meet the cultural needs of American Indian students (Cobern & Loving, 2001). It is inequitable that American Indian students do not see themselves and their cultures reflected in traditional public school science texts and curricula. At the confluence of often-undifferentiated science curricula and American Indian culture and language, there is a need for a responsiveness that benefits American Indian students. This present study illuminates the research question, “What is revealed about …

Understanding And Addressing Preservice Elementary Teachers’ Misconceptions In Science Education, Nicole Juliana Thomas

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prior research has demonstrated that both children and adults alike hold misconceptions about various scientific phenomena (Snyder & Sullivan, 1995; Driver et al., 1985). These misconceptions range from a variety of different fields, including astronomy and space science, environmental biology, and geology, among others (Miller & Brewer, 2010; Wandersee et al., 1994; Ritger & Cummins, 1991). Research suggests that the vast majority of misconceptions are formed early in a students’ educational career, and these misconceptions could be held throughout adulthood unless they are sufficiently addressed (Coley & Tanner, 2012; Posner et al., 1982; Nehm & Reilly, 2007; Sadler et al., …

The Activity Of Abstraction In Physical Chemistry Problem Solving And Instruction, Jessica M. Karch

Graduate Doctoral Dissertations

Productive problem solving, concept construction, and sense making occur through the core process of abstraction. Although the capacity for domain-general abstraction is developed at a young age, the role of abstraction in increasingly complex and disciplinary environments, such as those encountered in undergraduate STEM education, is not well understood. Undergraduate physical chemistry relies particularly heavily on abstraction because it uses many overlapping and imperfect mathematical models to represent and interpret phenomena occurring on multiple scales. To reconcile these models, extract meaning from them, and recognize when to apply them in problem solving requires processes of abstraction. This dissertation aims to …

Comparing Effectiveness And Perceived Characteristics Of Active Learning Methods In Undergraduate Biology Education, Linda R. Pesciotta

Dissertations - ALL

Although many undergraduates begin college as STEM majors, attrition rates from the field are high and numerous reports suggest that evidence-based teaching methods are critical for retention. Despite educators' research and near consensus that active learning is more effective than lecture, there are many types of active learning and the literature indicates their effects are not equivalent. The purpose of the current study was to directly compare different kinds of active learning by assessing their correlation with student performance (including learning gains) and understanding students' perceptions of them (including whether they contained Merrill's five principles of instruction and/or met three …

The Social Support Networks Of Students Who Identify As Black And Latino/A/X In Stem And Sbe Graduate Programs At Predominantly White Institutions, Kristi A. Tullis

Dissertations

Graduate students from historically underrepresented minority (URM) groups (those who identify as Black/African-American, Hispanic/Latino/a/x, Native American, Native Hawaiians/Pacific Islanders and/or Alaska Natives) encounter systemic and institutional hindrances to degree completion when enrolled in STEM doctoral programs at predominantly white institutions (Guiffrida & Douthit, 2010). Support networks have been identified as an important component for retention and success for graduate students from URM groups (Carlone & Johnson, 2007; Clewell, 1987; Johnson-Bailey, Valentine, Cervero, & Bowles, 2008; Joseph, 2012; Sweitzer, 2009). This study investigates the composition and structure of URM graduate students’ support networks, where their support comes from, in what capacity, …

Exploring The Nature Of The Co-Emergence Of Students' Representational Fluency And Functional Thinking, Nigar Altindis

Dissertations - ALL

Abstract In this dissertation, I explore ways to support secondary school students' meaningful understanding of quadratic functions. Specifically, I investigate how students co-developed representational fluency (RF) and functional thinking (FT), when they gained meaningful understanding of quadratic functions. I also characterize students' co-emergence of RF and FT on each representation (e.g., a graph, a symbolic equation, and a table) and across multiple representations. To accomplish these goals, I employed a design research methodology: a teaching experiment with eight Turkish-American secondary school students in an after-school context at a Turkish Community Center. I constructed the design principles and design elements for …
