The purpose of this study is to examine the influences certain factors have on the mathematical motivation beliefs of students in a predominantly African American setting. Mathematical motivation beliefs, for the purpose of this study, are defined as the components mathematical self-efficacy and mathematical value, both represented as dependent variables in the study. 4 independent variables were studied as potential influences regarding mathematical motivation beliefs. The variables included parental influences, teacher influences, mathematical anxiety, and the environment/setting. This research was conducted using 2 high schools in a rural area in East Mississippi. The 1st high school was predominantly African American and the 2nd high school was predominantly Caucasian. 4 scales were selected for this research study. The Mathematics Confidence Scale, developed by Dowling (1978), Mathematics Problems Performance Scale (Dowling, 1978), Fennema-Sherman Mathematics Attitude Scale (Fennema, 1976), and My Class Activities Survey (MCA, Schweinle & Mims, 2009) were all used. Findings revealed that teacher influence predicted the mathematical motivation beliefs of students in a predominantly African American school environment the most. Findings also indicated that math anxiety significantly predicted math value and self-efficacy in both classroom environments. Lastly, findings revealed that mathematical problem solving was significantly predicted by mathematical self-efficacy for students in a predominantly African American environment.

Thesis advisor: Andrew Miller / Despite reform, de facto segregation is still prominent in cities and towns across the country, and schools are no exception. White students are likely to attend schools that are 70% White, Black and Latinx students are likely to attend schools that are at least 50% Black or Latinx. Research has shown that predominantly White schools (>70% White) tend to perpetuate structural racism through tracking, inequitable grading practices, and parents’ opportunity hoarding. Furthermore, students of color in predominantly White schools often experience deficit thinking, racial spotlighting, microaggressions, and isolation. Since true integration of America’s public schools is not likely, it is important to determine how, if at all, school leaders perceive the emergence of anti-racism in predominantly White schools, especially given the disproportionate racial impact of the COVID-19 pandemic and raised consciousness around structural racism. It is also important to identify the conditions that support or constrain anti-racist initiatives in these mostly White spaces. Using qualitative methods, this case study of a predominantly White school district finds that anti-racism in predominantly White schools can be enacted, most notably in the areas of grading practices, leveling, curriculum, and student support programs. However, the findings also demonstrate that resistance from White teachers and parents, combined with a fear of burning teachers out, did not allow for accountability for anti-racist practices, which ultimately slowed the pace of systemic anti-racist change. / Thesis (EdD) — Boston College, 2022. / Submitted to: Boston College.

Current literature on Latino college student retention and attrition suggests that Latinos as a whole are becoming more successful at gaining admission to institutions of higher education. However, there is a need for support, guidance, and mentorship in order to ensure success once admitted. This study sought to test the effectiveness of a brief intervention for first year Latina/o undergraduate students at UT Austin, a predominantly White university. Sixty-nine participants were randomized into two groups, an experimental group (Educational Capital Guide Group) (n = 34) and a control group (n = 35). The intervention was based on Bourdieu’s Social Capital Theory and was designed to facilitate adjustment to college for Latinas/os. The two forms of Bourdieu’s capital addressed in this study were: the embodied state (i.e., knowledge individuals acquire via social membership), and the objectified state (i.e., physical resources accessible to an individual). Effects of the intervention were measured by observing changes in five outcome variables (i.e., academic worry, academic self-efficacy, anxiety, depression, and perceived university environment) from pre- to post-intervention for each group, as well as a comparison of GPA and novel on-campus resource use. Changes in outcome variables across college generation status for intervention participants were also assessed. Results indicated a statistically significant difference in perceptions of the university environment between experimental groups from pre- to post-intervention, but on no other outcome variables. Participants in the intervention group marginally outperformed control participants in end-of-semester GPA by the completion of their first semester. Similarly, participants in the intervention group used slightly more novel on-campus resources at posttest. Among intervention participants, although second generation college students reported statistically greater anxiety at both assessment periods, no between-group differences were found in responses to the intervention. Cultural and demographic variables that were found to be predictive of outcome variables, as well as a description of participant responses to their first semester at UT are discussed. The findings of this study offer implications for future intervention studies using social capital with Latinos as well as practices that should be addressed on an institutional level to support ethnic minority students’ success in higher education. / text

The focus of this study was to examine the relationship between principal ethnicity and other chosen demographics (community type of the school, average years of teacher experience, and percent of students qualifying as economically disadvantaged) and student achievement as measured by the Texas Education Agency?s (TEA?s) accountability rating system in predominantly Hispanic public high schools in Texas. The study sought to identify causal factors in relation to campus accountability rating and principal ethnicity in an effort to determine if principal ethnicity had an impact on student achievement in predominantly Hispanic public high schools in Texas. The study examined data obtained from the Texas Education Agency for the 2007-2008 school year. There were 335 schools that met the criteria set forth for the study. The findings of the study stated there was no statistically significant relationship between principal ethnicity and student achievement as measured by the TEA?s accountability system. There were some significant statistical findings in relation to principal ethnicity, accountability rating and indicators of community type of school, years of teacher experience, and percent of students qualifying as economically disadvantaged. Moderate relationships were found between community type and accountability rating and between community type and ethnicity of the principal. There were also significant relationships found between accountability rating and average years of teacher experience as well as principal ethnicity and percent of students qualifying as economically disadvantaged. There was no significant finding between principal ethnicity and average years of teaching experience. There was also no significant finding in relation to accountability rating and percent of students qualifying as economically disadvantaged. The growing number of Hispanic students entering schools is leading to more campuses becoming predominantly Hispanic in student population. The achievement gap between Hispanic students and White students has continued to be an ongoing problem and important issue. The findings of this study show that ethnicity of the principal does not have an impact on student achievement in predominantly Hispanic public high schools in Texas. Hiring administrators should focus on hiring school leaders who possess identified characteristics that lead to improved student achievement.

One area of identity that challenges dominant ideals of professional, neat, or appropriate appearance is Black hair. Although Black hair expression is frequent in media, politics, and pop culture, there still remains a perceived stigma surrounding its presence in positions and environments (e.g. tenure positions or predominantly White institutions) that ironically promote a mission of diversity and inclusion. Black women, no matter their rate of graduation, level of intellect, status or achievement are not exempt from the challenges of bias, perception, stigma, stereotype or marginalization within majority White hierarchal spaces such as the academy. This includes Black female faculty who hold positions of high status, such as tenure. The presence of Black hair expression in these positions challenges others, as well as Black women, to accept images of Black beauty and Black identity. This study aims to explore how tenured Black female faculty navigate professional challenges with hair expression surrounding identity (i.e. sexism and racism) and the value of the Black visage in the academy. In addition, this study investigates and brings attention to current thoughts on Black hair perception, microaggressions, stigma, stereotype, and assimilation issues that Black female faculty experience with their hair as they navigate the academy.

Nonverbal Learning Disability (NVLD) is a syndrome characterized by impaired social perception, visual-spatial skills, fine motor coordination, and mathematics abilities. Researchers have found that children with NVLD often have significant symptoms of inattention, and there is evidence that the majority of children with NVLD also meet clinical criteria for Attention Deficit/Hyperactivity Disorder, Predominantly Inattentive Subtype (ADHD:PI) (Brown, 2000; Gross-Tsur & Shalev, 1995; Voeller, 1996). Although significant overlap is observed between NVLD and behavioral symptoms of ADHD, little research has focused on the specific attention problems of children with NVLD. Given the high incidence of co-morbid attention problems with NVLD (Brown, 2000), many researchers have proposed that overlapping neural regions are responsible for the similarity in attention impairments observed in both NVLD and ADHD:PI (Denckla, 2000; Stefanatos, 2001). Other researchers suggest that there are distinct neurological impairments in children with NVLD and both subtypes of ADHD that result in attention problems. Specifically, Rourke (1995) suggested a developmental sequence that results in generally intact auditory attention with impaired attention for visual stimuli in children with NVLD. This study sought to reconcile the discrepancy between conceptualizations of attention problems in children with NVLD. It was hypothesized that children with NVLD would exhibit distinct profiles of strengths and weaknesses on neuropsychological measures of attention compared to children with ADHD, Predominantly Inattentive Subtype (ADHD:PI) and ADHD, Combined Subtype (ADHD:C). Specifically, it was expected that the three diagnostic groups would differ on the neuropsychological measures depending on the attention modality (auditory vs. visual). Extant neuropsychological data from 88 children between the ages of 9 and 15 years of age with diagnoses of NVLD, ADHD:PI, and ADHD:C were analyzed. Neuropsychological measures of processing speed, working memory, vigilance, and inhibition were examined to compare specific domains of attention functioning in the three groups. Evidence from the current study supported the model in which NVLD and the two ADHD subtypes represent a continuum of dysfunction dependant on overlapping neural regions. Moreover, specific attention strengths and weaknesses in children with NVLD compared to children with ADHD:PI, ADHD:C, and normative data were identified in order to inform clinical diagnosis and intervention. / text

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most commonly diagnosed of child clinical syndromes and is associated with poor academic achievement, poor peer and family relations, and an elevated risk for anxiety, depression, and conduct disorder (Barkley ,1990; Barkley, Guevremont, Anastopoulos, DuPaul, & Shelton, 1993; Barkley, Murphy, & Kwasnik, 1996; Beiderman, Faraone, & Lapey, 1992; Fischer, Fischer, et al., 1990; Hinshaw, 1994; Nadeau 1995; Weiss & Hechtman, 1993). Although ADHD is one of the most commonly diagnosed and widely researched disorders, the diagnostic criteria and defining characteristics of ADHD remain controversial (Wolraich, 1999). The current diagnostic formulation, as specified by the DSM-IV-TR, includes three distinct subtypes: Attention Deficit Hyperactivity Disorder- Predominantly Hyperactive Impulsive Type (ADHD-H), Attention Deficit Hyperactivity Predominantly Inattentive Type (ADHD-PI) and Attention Deficit Hyperactivity Disorder- Combined Typed (ADHD-C). Perhaps the most controversial aspect of the current nosology is the inclusion of the inattention symptoms within the family of ADHD diagnoses (Milich, Balentine, Lynam, 2001). Researchers and clinicians have further posited that ADHD-PI represents a distinct disorder with two subtypes: inattentive-disorganized and sluggish cognitive tempo. This study explored the relation between reading fluency, sluggish cognitive tempo symptoms, disorganized symptoms, processing speed and ADHD diagnosis. This study examined performance of children diagnosed 77 children diagnosed with ADHD (i.e. 53 participants met criteria for ADHD-PI and 24 participants met criteria for ADHD-C) on measures of cognitive functioning, processing speed, behavioral reports, sluggish cognitive tempo, disorganization and reading fluency. Significant group differences did not emerge on measures of processing speed, sluggish cognitive tempo symptoms or disorganized symptoms. Path analysis was employed to examine the simultaneous effects of processing speed on inattention symptoms, hyperactive/impulsive symptoms, SCT symptoms, DO symptoms, reading fluency, and internalizing symptoms. In addition, the paths from SCT symptoms, DO symptoms, inattention symptoms, and hyperactive/impulsive symptoms to reading fluency and internalizing symptoms were also be examined. Processing speed had a significant direct effect on SCT symptoms, Inattention Symptoms and Reading Fluency. In addition, SCT symptoms had a significant direct effect on anxiety symptoms. In summary, findings from the study provide important information about the link between processing speed, attention written, and reading fluency. Limitations of the study and implications for future research and practice are discussed. / text

The purpose of this phenomenological study was to explore the lived experiences of economically disadvantaged, Black students attending predominantly White, elite private boarding schools. Data were collected utilizing semi-structured interviews with 9 participants, with each interview lasting approximately 90 minutes. The recursive method of data collection and analysis was informed by six steps outlined by Creswell (1998), as well as Consensual Qualitative Research (CQR) methods (Hill, Thompson, & Williams, 1997). Findings revealed 9 themes associated with participants' experiences: classroom experiences, value of Black peer networks, caught between two worlds, racial perceptions, desire to connect with people of all races, socioeconomic challenges, living away from home challenges, impact of peers on level of success, and significance of relationships with Black faculty. Practice and research implications for Black students attending private school, as well as for private school faculty and administrators, are discussed.

abstract: Black male students experience a number of issues related to identity during the persistence process, which have potential to deter them from graduating. Some of these issues include feeling isolated and lack of access to resources due to their ethnic and/or racial identities. Recent statistics indicate that though there is an increase in college enrollment for Black students, the graduation rate is disproportionate to their enrollment. Using critical race theory, co-cultural theory, and communication theory of identity, this study investigated the role of identity in the persistence of Black male students’ graduation rates. Specifically, the central question was ‘What role, if any, do identity processes play in Black male students' decisions to continue or depart from a Predominantly White Institution?’ In order to answer this question, fifteen first-generation Black male college students were interviewed in order to understand the specific experiences that impacted them in relation to graduation. The study sample included a subset of Black male athletes who were found to have distinct differences in college experiences based solely on their athlete status. The overall results indicate that Black male students have expectations of the persistence process and that their personal identity also plays a significant role in the persistence process. In order to maintain their identities and continue with coursework, Black males enacted persistence strategies that were consistent with an overall goal of graduating. Research findings suggest that Black males must maintain a strong personal identity in order to maintain their personal commitment to graduation and college institutions can support them in this endeavor. Research outcomes also suggest that Black males should have a plan of persistence upon entering college, which is constantly reinforced as a graduation motivator. / Dissertation/Thesis / Doctoral Dissertation Communication 2015

Abstract Stickler and Marshall syndromes are genetic disorders both inherited in an autosomal dominant manner. The genotype-phenotype correlation was performed in ten Stickler/Marshall syndrome patients with mutations in the COL11A1 gene. Four patients had a phenotype classified as Marshall syndrome based on early-onset severe hearing loss and characteristic facial dysmorphism. A splice site mutation in intron 50 of COL11A1 was found in these patients, while the remaining six patients had an overlapping Marshall-Stickler phenotype with a mutation elsewhere in the gene. These results indicate exon 50 as a hot spot for splice site mutations leading to a phenotype of Marshall syndrome rather than Stickler syndrome. Collagen II (COL2A1) precursor mRNA undergoes alternative splicing resulting in two different isoforms, IIA including exon 2 and IIB excluding exon 2. Recent evidence indicates that premature termination codon mutations in exon 2 cause Stickler syndrome with no or minimal extraocular manifestations. Two mutations were observed in this study: Cys64Stop, and a novel structural mutation, Cys57Tyr. Results from the COL2A1 mini-gene studies suggested that both mutations altered positive cis elements for splicing resulting in a lower IIA:IIB ratio. The results further emphasize the importance of exon 2 in the development and normal function of the eye. In addition, patients displaying eye phenotypes in the absence of extraocular manifestations should be analyzed first for exon 2 mutations. Linkage analysis identified a new locus for autosomal recessive nonsyndromic hearing loss (DFNB32) on chromosome 1p13.3-22.1 in a Tunisian family with congenital profound autosomal recessive deafness. The COL11A1 gene is located in this region and was analyzed as a candidate gene. No disease causing sequence variation was observed. The analysis of 85 English and 40 Finnish subjects with high myopia resulted in the identification 23 sequence variations in the SLRP genes LUM, FMOD, PRELP, and OPTC. The two intronic variations and seven amino acid changes, one synonymous and six non-synonymous, were not found in the 308 controls analyzed. Five changes were detected in opticin, and all but one were shown to co-segregate with high myopia in families with incomplete penetrance. The results suggested that sequence variations in the SLRP genes expressed in the eye are genetic risk factors underlying the pathogenesis of high myopia.
