Cumulative Advantage And Student Performance In General Chemistry: An Empirical Study At A Midwest Tier 1 University (2016-2019), Nicole Barvian

Dissertations

General chemistry (GC) plays a crucial role in the academic and career outcomes of students interested in postsecondary science, engineering and medicine. As a whole, chemistry education research literature has reported student attrition rates averaging from 25% to 35% for nearly a century. Student attrition rates can be attributed to a number of factors, including high school preparation (e.g. Tai et al. 2006), opportunity to learn (Carroll, 1989) and accumulated time and practice in a domain (e.g. Ericsson et al. 1993). The factors, in turn, are affected by mechanisms of social stratification, in particular, the social mechanism of cumulative advantage …

Simulating Strongly Coupled Many-Body Systems With Quantum Algorithms, Manqoba Qedindaba Hlatshwayo

Dissertations

The complexity of the nuclear many-body problem is a severe obstacle to finding a general and accurate numerical approach needed to simulate medium-mass and heavy nuclei. Even with the advent of exascale classical computing, the impediment of exponential growth of the Hilbert space renders the problem intractable for most classical calculations. In the last few years, quantum algorithms have become an attractive alternative for practitioners because quantum computers are more efficient in simulating quantum physics than classical computers. While a fully fault-tolerant universal quantum computer will not be realized soon, this dissertation explores quantum algorithms for simulating nuclear physics suitable …

Promoting Equal Interactions In Early Childhood Settings, Daphne Snyder

Dissertations

In the United States, Black, Indigenous, and People of Color (BIPOC) students are more likely to face disciplinary action (e.g., exclusion, suspension, and expulsion from the classroom) for engaging in the same challenging behaviors as their white peers (Badger et al., 2018; Little & Tolbert, 2018; Noguera, 2003). Due to the discrepancy in disciplinary practices, students are at risk of continued negative interactions with their teachers (Decker et al., 2007; Wymer et al., 2020). One way to improve teacher interactions toward BIPOC students is through equity-focused performance feedback regarding praise and reprimand rates (Knochel et al., 2022). The purpose of …

‘Poor Hockey Behaviors’: Athletes’ Moral Acculturation Experiences In Youth Hockey, Zachary Colter Mccarver

Dissertations

Competitive youth sport requires athletes to persistently decide what the moral course of action is across situation (Boardley, 2020; Rest, 1984). Sport cultures that contain coaches who endorse a win at all cost mentality encourage athletes’ engagement in behaviors that are detrimental to their opponents to achieve competitive success (Boardley & Kavussanu, 2007). Bandura (1991) proposed that environmental processes can alter how an individual determines the moral course of action through the anticipation of behavior to produce self-referenced positive consequences, such as pride or satisfaction. The purpose of this study was to explore athletes’ moral acculturation experiences within hockey culture …

In order to offer a …

The Effect Of Parceling On The Measurement Invariance Of Us Students’ Trends In International Mathematics And Science Study (Timss) 2015 Math Attitude Scores, Kritika Thapa

Dissertations

Measurement invariance is crucial for making valid comparisons across different groups (Kline, 2016; Vandenberg, 2002). To address the challenges associated with invariance testing such as large sample size requirements, the complexity of the model, etc., applied researchers have incorporated parcels. Parcels have been shown to alleviate skewness, improve reliability, reduce the number of indicators, and produce a more stable solution (Bandalos & Finney, 2001; Matsunaga et al., 2021; Nasser & Takahashi, 2003). Despite these benefits, limited methodological research has been conducted on the effects of parcels on tests of measurement invariance. This dissertation investigated the effects of different total sample …

The Impact Of Historical Narratives On Students' Nos Understanding And Science Motivation, Peng Dai

Dissertations

Scholars over the past few years have drawn attention to the enormous potential role historical stories can play in promoting student understanding of issues associated with the nature of science (NOS). Such stories, often referred to as “historical narratives,” are thought to do so by providing a rich historical context within which students are acquainted with how scientists in the past reasoned about scientific phenomena. Klassen (2009) developed a theoretical framework that identifies ten essential elements that must be present to qualify as a historical narrative. Only a few studies have empirically assessed the merits of Klassen’s framework, and in …
