This two-part study included a content analysis of an AP art history text and a survey together with interviews with AP art history teachers that embraced both quantitative and qualitative research methodologies. The first phase of the study examined one of the more popular art history survey texts in the AP art history program, Gardner’s Art through the Ages, in terms of how inclusive it is in addressing issues of sexual orientation and, particularly, same-sex perspectives. In addition, the text was examined for evidence of sexual orientation ignored – particularly same-sex perspectives ignored and for heteronormative hegemonies. The second phase investigated the understandings and opinions of AP art history teachers toward the inclusion of sexual orientation and same-sex perspectives in their curriculums and classrooms. Recent recognition of gay, lesbian, and same-sex perspectives in the study of art history has challenged art educators and art historians to begin to consider opening up their curriculums and writings to include these perspectives. These ignored perspectives produce important understandings that enrich and deepen the discourse of art history. The inclusion of gay and lesbian content and same-sex perspectives to the study of AP art history, not only effectively serves the needs of AP art …

Spatial ability is the skill associated with mental relations among objects, the process of maintaining the physical aspects of an object after mentally rotating it in space. Many studies report a strong association of spatial ability with success in various areas of health care, especially surgery, radiology and dentistry. To date, similar investigations in professional nursing could not be located. Registered nurses, employed in an acute care multi-hospital setting, were surveyed using the Shipley-2Block Pattern Test, the Group Embedded Figures Test, and a newly created test of general nursing knowledge. The sample size of 123 nurses was composed of 31 male nurses and 92 female nurses. Data was collected between May and August of 2013 and analyzed using R, version 2.15.2. The present study did not demonstrate a statistically significant effect for gender differences on two measures of spatial ability. However, Cohen’s d effect sizes for mean gender differences in the present study are consistent with prior studies. This may suggest the nursing profession is comparable with other professions where males perform higher than females on spatial ability. The present study should be considered an initial step toward evaluating the relevance of spatial ability in the performance of nursing care.

Since the time of Pythagoras, philosophers, educators, and researchers have theorized that connections exist between music and mathematics. While there is little doubt that engaging in musical or mathematical activities stimulates brain activity at high levels and that increased student involvement fosters a greater learning environment, several questions remain to determine if musical stimulation actually improves mathematic performance. This study took a qualitative approach that allowed 24 high school students to express their direct experiences with music and mathematics, as well as their perceptions of how the two fields are related. Participants were divided into four equal groups based on school music participation and level of mathematic achievement, as determined by their performance on the Texas Assessment of Knowledge and Skills (TAKS). Students participated in a series of three interviews addressing their experiences in both music and mathematics, and took the Multiple Intelligences Developmental Assessment Scales (MIDAS). TAKS data and MIDAS information were triangulated with interview findings. Using a multiple intelligence lens, this study addressed the following questions: (a) How do students perceive themselves as musicians and mathematicians? (b) What experiences do students have in the fields of music and mathematics? (c) Where do students perceive themselves continuing in the …

Religion and spirituality are vital aspects of many people’s lives both in the United States and across the globe. Although many constructs and measures exist to describe and assess the experience of pursuing the sacred, the complexity of religious and spiritual experience leads to mixed results in relation to well-being and psychopathological traits. However, in broad terms, the relationship appears positive. Over the past 30 years the need for more refined and useful approaches to the study of religious and spiritual behavior has been repeatedly acknowledged. Although authors wisely caution development of further measures without due cause, extant constructs and measures do not provide clear and consistent results for understanding the influence of one’s relationships to religion and spirituality upon behaviors of clinical interest. The present project drew from the functional contextual concept of psychological flexibility, which provides clarity to understanding the encouragement and maintenance of psychological well-being. A new construct of religious and psychological flexibility is explicated as a functional approach to understanding religious and spiritual behavior in a manner that is useful in research and clinical settings alike. The development and evaluation of the Measure of Religious and Spiritual Flexibility (MRSF) is described. The MRSF evidenced adequate internal …

The purpose of the study is to describe the current status of and the relationships between teacher self-efficacy and in-service teachers’ perceptions and/or attitudes of (a) the quantity and quality of feedback from formative evaluation, (b) toward feedback from formative evaluation, and (c) the impact of feedback from formative evaluation on teacher self-efficacy. In addition to calculating correlation coefficients, 6 teachers were interviewed – 2 each from high, medium, and low efficacy schools. The quantitative data reported low, positive correlations between all of the factors. Statistically significant correlations were found between 8 of the 12 factors including teacher attitudes toward feedback from formative evaluation and: overall Teacher Sense of Efficacy Scale (r = .302), student engagement (r = .309), instructional strategies (r = .237) and classroom management (r =.266). Other statistically significant correlations were found between teacher perceptions of the impact of feedback from formative evaluation and its relationship to self-efficacy and: overall Teachers’ Sense of Efficacy Scale (r = .295), Student Engagement (r = .300), Instructional Strategies (r = .209), and Classroom Management (r = .282). The face-to-face interviews and online focus group supported the quantitative findings as the participants reported that they value formative evaluation and feedback and …

The City of Dallas Environmental Education Initiative (EEI) is a hands-on, inquiry-based, K-12 water conservation education program that teaches students concepts about water and specific water conservation behaviors. Few descriptions and evaluations, especially quantitative in nature, of water conservation education programs have previously been conducted in the literature. This research measured the quantitative effects and impacts of the education program on water use in single-family homes in Dallas, Texas. A total of 2,122 students in 104 classrooms at three schools in the Dallas Independent School District received hands-on, inquiry-based water conservation education lessons and the average monthly water use (in gallons) in single-family homes was analyzed to measure whether or not there was a change in water use. The results showed that over a period of one calendar year the water use in the single-family homes within each school zone and throughout the entire research area in this study experienced a statistically significant decrease in water use of approximately 501 gallons per home per month (independent, t-test, p>0.001). Data from this research suggests that EEI is playing a role in decreasing the amount of water used for residential purposes. Additionally, this research demonstrates the use of a quantitative tool by …

Crocodilians and birds comprise sister taxa of archosaurs, the development of these vertebrates occurs within an egg case that leaves developing embryos susceptible to fluctuations in the nesting environment. Studies suggest that sub-optimal conditions alter morphological growth and cardiovascular physiology. Regulation of the cardiovascular system is immature in the subjects studied, and embryos may rely on humoral rather than neural control of the cardiovascular system. The primary focus of this dissertation was to assess regulatory mechanisms responsible for maintenance of arterial pressure and heart rate. Dehydration stress had marked effects on embryo growth, and altered baseline cardiovascular parameters, while leaving the response to humoral regulator, angiotensin II (Ang II), unaffected. However, dehydrated alligator embryos developed cholinergic tone on heart rate. Hypoxic incubated chicken embryos were reduced in embryo mass, and altered response to humoral regulatory components Ang I and adenosine in addition identifying a novel regulatory component of the cardiovascular response to acute hypoxia. Collectively, these studies add to the existing knowledge of cardiovascular physiology in embryonic archosaurs and suggest that some components of cardiovascular regulation are plastic following developmental stress.

This present study examined the structural validity of a Chinese version of Multidimensional Work Ethic Profile (MWEP-C), using a large sample of Chinese parents and their young adult children (N = 1047). Confirmatory factor analysis (CFA) was applied to evaluate the model fit of sample data on three competing models using two randomly split stratified subsamples. Measurement invariance for these two generational respondents was checked using differential item functioning (DIF) analysis. The results indicated that MWEP-C provided a reasonable fit for the sample data and the majority of survey items produced similar item-level responses for individuals that do not differ on the attributes of work ethic across these two generations. DIF items were detected based on advanced and successive iterations. Monte Carlo simulations were also conducted for creating threshold values and for chi-square probabilities based on 1,000 replications. After identifying the DIF items, model fit improved and generational differences and similarities in work ethic between parents and their young adult children were also identified. The results suggested that the younger Chinese generations have higher work ethic mean scores on the dimensions of work centrality and morality/ethics while they have similarities on time concept, self-reliance, delay of gratification, and hard work …

“In what ways does teaching with folk arts inspired visual arts-based instruction enhance community building among elementary students in a Title I school?” was the primary research question in this study. Agreeing with past and present day research that the construct of community is vital to social and cultural capital, this research attempts to determine how the notion of community benefits both students and teachers in the elementary art classroom. Folk art was utilized because this genre was accessible in terms of locality and familiarity among students and teachers. The purpose of this investigation was to produce teaching strategies and methods that show how community can be formed in the art classroom. The participants were elementary students, Grades 2 and 3, in a Title I school located in Denton, Texas. This investigation was conducted under an action research methodology. This approach to research is intended to be transformational, emergent, and accommodating. I recorded observations, field notes, and conversations from the participants. Emergent themes were discovered through content analysis and conceptual maps. Results from this investigation concluded transformation is only possible if the person wants change to happen. Data also showed that community and art education are symbiotic. Transformation, growth, and …

Individual personality traits of pre-service teachers may have a significant influence on their confidence in teaching. Confidence in teaching does not always align with the experience of pre-service teachers. simSchool enables transformational experiences for teacher candidates to improve in general teaching skills, connect learning theories in the classroom, and develop confidence to be an effective teacher without the ill impacts of practicing on real students. This study executed a quasi-experimental design to explore the personality traits of 152 pre-service teachers and examined how their perceptions of teaching confidence and teaching experience were related in the context of simSchool. A treatment and comparison group completed the Survey of Teaching Skills pre/post tests and the OCEAN survey for quantitative data analysis to investigate four research questions: 1. Is there a difference between treatment and comparison groups on educator’s gains in confidence and experience? 2. Is there a relationship between personality type and perceived teaching effectiveness? 3. Is there a relationship between personality attributes and pre-service educator ratings of teaching experience in a simulated teaching environment? 4. Is there a relationship between personality attributes and pre-service educator ratings of teaching confidence in a simulated teaching environment? Findings from repeated measures MANOVA tests indicated …

Baroque music is an area largely neglected in the music education of young horn students and wind players in general. Baroque horn repertoire is very demanding primarily due to the range. Baroque composers wrote for horn using the uppermost register of the instrument. In this range the partials are closer together, allowing for more melodic writing. This music requires an advanced level of technique, endurance, and ability. Often this repertoire is not suitable for students until they are well into their collegiate years of study. Frequently this music is performed on descant horns. Since only a small number of middle school and high school horn students continue to play after they leave their school band programs, they many never get first hand experience performing Baroque music. Vocal students are often introduced to Baroque arias early in their training. Purcell’s songs and arias are an excellent example of the literature that young voice students use. These arias and songs can be the perfect portal to Baroque music for horn students as well. Here I have created an edition of Henry Purcell’s songs and arias for young horn students. Each aria used the text as a guide for the “affect” and its …

The current study replicated and extended previous research by examining empirically the direct and indirect influence of social pressure (to lose weight and diet), social body comparisons, internalization of the thin ideal, body dissatisfaction, self-esteem, and cardiorespiratory fitness on self-reported dietary restraint in a diverse sample of middle school boys (n = 663); Mage was 12.49 years (SD = .99). With IRB approval, parental consent, and child assent, during annual FITNESSGRAM testing, participants completed questionnaires that measured the study’s constructs. Cardiorespiratory fitness (CRF) was determined by the boys’ performance on the PACER running test. The proposed model was examined using structural equation modeling (SEM). Because measures demonstrated univariate and multivariate normality, the maximum likelihood procedure within EQS to examine the measurement and structural models was used. Fit was determined using a two-index procedure. Participants were randomly split into exploratory (Sample A - 331) and confirmatory (Sample B - 332) samples. For Sample A, the measurement and structural models fit the data well. The structural model was confirmed in Sample B, with the same paths being significant and nonsignficant. For both Sample A and Sample B, 35% of the Dietary Restraint variance was explained. These findings support a multifactorial approach to …

The purpose of this study is to identify novice teachers’ perception of their preparedness to teach a class designed for students with autism spectrum disorder (ASD) after graduation from a traditional university-based special education program or from a special education alternative certification program. Teacher preparedness and the need for highly qualified teachers of students with ASD are relevant topics, as the prevalence rate of ASD continues to increase. This phenomenological qualitative study explores novice teachers’ perceptions of preparedness to teach students with ASD and their knowledge about teaching students with ASD. Semi-structured, in-depth interviews were conducted with six novice special education teachers of students with ASD. Results indicated that novice teachers of students with ASD have knowledge of autism and evidence-based practices (EBP), which they ascertained primarily through experiences such as; working directly with students with ASD, however, preservice education programs provided the participants with cursory information related to knowledge of ASD and EBP.

Estimates of healthy years of life lost due to mental illness are increasing, calling greater attention to the provision of effective psychotherapy services. Hypothesized to be the key mechanism through which competencies are developed in trainee clinicians and subsequent client outcomes, clinical supervision is deserving of greater attention. Drawing on a sample of supervisors, trainees, and clients from a training clinic, the present study sought to clarify the relational factors that could facilitate the asserted supervisor-client outcome link and to better understand if, and how, clinical supervisors influence client outcomes. With the exception of supervisor openness to experience, supervisor factors did not predict meaningful variance in client outcomes. Trainee extraversion and openness to experience predicted significant variance in leader-member exchange and supervisory working alliance. Dispositional trainee factors (e.g., personality) appear to impact trainee perceptions of the supervisory relationship. Implications for training and development are discussed, in addition to directions for future research.

Penderecki made a tremendous variety of contributions to the cello repertoire. His profound respect for tradition and for his past is deeply appreciated by both performers and audiences. In each individual composition, he explored the cello’s sonorous possibilities and created a new technical and musical palette for the instrument. He worked with legendary, world-renowned cellists who not only gave the premieres of his works but also established deep friendships with him. The Divertimento/Suite for Cello Solo (1994-2013), a compilation of miniature movements, each with its sophisticated structure, demonstrates Penderecki’s three compositional style periods. Baroque and Romantic elements in each movement are achieved within their style characteristics. Penderecki’s Divertimento/Suite for Violoncello Solo is composed of eight contrasting movements that were written during a nineteen-year period. The work is characterized by a Neo-Romantic aesthetic and utilizes the cello’s dark lyrical tones with a variety of timbre and tonal contrasts. The purpose of the present study is to create a practical performance guide to this important musical work with a detailed stylistic, textural, and motivic analysis of all eight movements. Although there are many published documents and analyses of Penderecki’s orchestral, choral, chamber and other solo pieces, the Divertimento/Suite for Cello Solo has …

This study explored the beliefs of pre-service secondary mathematics teachers about project-based learning (PBL), as they encountered a project-based learning high school where they implemented a project-based unit of instruction. A qualitative study was conducted with one undergraduate cohort in a higher education science, technology, engineering, and mathematics (STEM) national initiative that has 40 U.S. replication sites. Using teaching philosophy statements and focus group discussions, the beliefs of STEM pre-service secondary teachers are made visible. The findings from this study reveal a recurring theme: the process of how these pre-service teachers seemed to evolve and mature as teachers, from novice toward becoming an expert, as they asked themselves internal questions that are common to developing teachers. These pre-service STEM teachers experienced 1) internal questions about their own growth as a potential teacher, as evidenced through their verbal and written statements; 2) tension between PBL content and pedagogy; and 3) tension between practice and theory. The findings also infer that there are potential critical variables that may contribute to pre-service teachers’ beliefs. Those variables identified were the following: 1) the sequence of when the project-based instruction (PBI) course was taken; 2) time, as related to when the participant took the PBI …

This phenomenological study investigated the transition experiences of clinical respiratory therapists who pursued second careers as respiratory faculty. Situated Learning Theory and Workplace Learning Theory were the frameworks for interviews with 11 second career respiratory faculty who had taught fewer than five years in baccalaureate degree programs. The goal of this study was to identify the major themes of their experiences. Thematic analysis revealed five common experiences: under-preparation, challenges, overwhelmed feelings, personal responsibilities, and rewards. The common theoretical framework for all participants was the critical need to understand their communities of practice within their organizations. From this study, respiratory department chairs and administrators may better understand the challenges and needs of clinical therapists as they transition into faculty positions. Positive experiences such as improved orientations and continued effective faculty support may promote a more rewarding and long-term practice.

The student success rates for three developmental mathematics courses (prealgebra, elementary algebra, and intermediate algebra) taught through four instructional methods (lecture, personalized system of instruction [PSI], hybrid, and online) were examined. The sample consisted of 9,211 students enrolled in a large Texas community college from fall 2009 through spring 2011. Student success was defined as a grade of C or better. Chi-square tests were used to compare the three developmental mathematics courses success rates. Statistically significant differences in student success were found between all four methods of instruction for all three mathematics courses (prealgebra: χ2 [df = 3] = 107.90, p < 0.001; elementary algebra: χ2 [df = 3] = 88.39, p < 0.001; intermediate algebra χ2 [df = 3] = 254.18, p < 0.001). Binary logistic regression modeling was used to determine to what extent age, gender, ethnicity, residency, Pell eligibility and mode of instruction accounted for the community college students’ course success for each of the three developmental mathematics courses. For prealgebra, the independent variables of gender, race, age, residency, and mode of instruction made statistically significant contributions to the model (χ2 [df = 14, n = 1,743] = 159.196, p < .001; Nagelkerke R2 = .119), with …

This study investigated the beliefs of teachers at a particular elementary campus in North Texas during its first year of implementation of a social emotional curriculum regarding teaching social emotional skills and the influence of those beliefs on their classroom practices. The study drew from the works of Dewey and Bandura in the development of a framework for teacher decision making. A case study design incorporating multiple cases within the case study utilized a mixed-methods approach for data collection and analysis. Ten teachers volunteered and participated in the quantitative data collection, and four of those ten participated in the qualitative data collection through interviews and classroom observations. Data collection methods also included a demographic survey, a questionnaire on teacher beliefs about social emotional learning, and a self-ranking scale of practices related to teaching social emotional skills. Results indicated that although all participants believed social emotional skills instruction was part of their duties as teachers, their practices in teaching social emotional skills varied. Additionally, there was a mismatch between participants’ self-identified practices and the practices that were observed during the study. Administrative support for program implementation was high, but did not necessarily translate to effective practices during the first year of …

This study examined parental perceptions of marketing to young children using a feminist post-structural theoretical framework to specifically examine the following questions, 1) To what extent are parents aware of the marketing tactics being directed toward young children? 2) How do power/knowledge relations and practices produce parent’s multiple subjectivities as they parent their children in regards to commercial culture? 3) How can early childhood educators adapt pedagogy and practice in order to meet the needs of children growing up within the context of a commercialized childhood? In-depth unstructured interviews revealed that parents within this study tend to view themselves as solely responsible for their children and do not support governmental regulation of the advertising industry. In most cases, the parents in the study empathized with marketers trying to sell their products to children. Furthermore, while participants in this study were concerned about how consumer culture influences children’s subjectivities, they were more concerned about “adult content” than corporate access to children. Many of the parental perceptions uncovered mirror neoliberal discourses including an emphasis on individual responsibility, the belief that government regulation is censorship and the privileging of economic rationale by systematically representing children as sources of profit. This study utilized Deleuzean …

The aim of this dissertation is to lay the groundwork for an integrated approach to violin instruction for children who are not being groomed explicitly for professional careers as instrumentalists. The study presents a particular focus on the age of middle school children, in order to showcase a more specialized and definitive result of research without, however, distinguishing between advantages and limitations of different age groups of children who study music and learn to play the violin. My first goal is to craft a sample method of teaching with a premise that not all students studying music must or need to become professional musicians in their future. I promote an approach based on the premise that music has universal value available to all and that any kind of music education encourages the growth, personality development, and imagination of children. My second goal is to explore how music education functions in 21st century western culture. Research is based on teachings and methods established by Suzuki, Kodaly, Jaques-Dalcroze, and Orff, among others.

This study applies an empirical research method determine whether Texas public school principals’ leadership styles, coupled with their use of real time data in a data warehouse, influenced their leadership ability as measured by student achievement. In today’s world of data rich environments that require campuses and districts to make data-driven decisions, principals find themselves having to organize and categorize data to help their school boards, campuses, and citizenry make informed decisions. Most school principals in Texas have access to data in multiple forms including national and state resources and a multitude of other data reports. A random sample of principals was selected to take the Multi Factor Leadership Questionnaire (MLQ5x) and the Principals Data Use Survey. The MLQ5x measured principals’ leadership styles as transformational, transactional, or passive avoidant. The Principals Data Use Survey measured how principals use data to inform campus decisions on student achievement, shaping the vision of the campus, and designing professional development. Data obtained from the survey were correlated to determine the relationship between principals’ use of data warehouses and their leadership styles on student achievement as measured by the Texas Assessment of Knowledge and Skills. The results yielded significant relationships between student achievement, principals’ leadership …

As non-institutional digital image collections expand into social media, independent non-professional image curators are emerging, actively constructing alternative naming conventions to suit their needs in a social collecting environment. This project considers how independent user-curators are developing particular sense-making behaviors as they actively contribute names to large, unstructured social image collections. In order to capture and explore this evolving language adaptation, Pinterest names are analyzed using a matrix composed of Panofsky’s three strata of subject matter, Rosch’s levels of categorical abstraction, Shatford Layne’s image attributes and Wittgenstein’s language game constructions. Analyzing Pinterest image names illuminates previously unnoticed behaviors by independent user-curators as they create shared collections. Exploring the various language choices which user-curators select as they apply this new curating vocabulary helps identify underlying user needs not apparent in traditionally curated collections restricted to traditional naming conventions.

This quantitative study utilized secondary data from one large four-year, state university in the southwestern US. The relationship between registration time and academic performance was examined as well as the relationship between registration time and retention of first-time-in-college (FTIC) undergraduate students during their first semester of enrollment at the university. The differences between decided and undecided students were tested regarding students’ academic performance and retention of the same population. The study population for the fall 2011 semester included 6,739 freshmen, and the study population for the fall 2012 semester included 4,454 freshmen. Through multiple and logistic regression models, registration time was shown to statistically have a relationship with academic performance and retention (p < .05). Later registrants showed to have a negative relationship with GPA and were less likely to return the following spring semester. The explained variance (R2) for both measures of academic performance and retention along with descriptive statistics are also presented. A Mann Whitney U test and chi square test indicated that a statistically significant association between decided and undecided students exists for academic performance and retention (p < .05). Decided major students performed better as measured by semester GPA performance and were more likely to return …
