Years of teaching experience have long been taken as an important indicator of teacher and school quality in primary and secondary schools. However, research on the effects of teacher years of experience on student outcomes has shown mixed results. To investigate the source of variation causing these mixed results, this study examined a broad range of student and classroom compositions that might affect the relationship between teacher years of experience and student outcomes, including standardized test scores in English Language Arts and Mathematics, Social-Emotional Test scores, and the count and severity of student disciplinary incidents. Using multilevel regression, this study analyzed longitudinal data obtained from the largest school district in the state of Arizona, Mesa Unified School District, which is classified as a mid-high poverty district. Despite the large sample size, a very weak and non-significant relationship was found for teacher years of experience on any student outcome. In contrast, student and family demographic backgrounds were significantly related to student outcomes. English and Math scores were significantly associated with student giftedness, home languages, and English learning status. Social-emotional test scores were significantly related to race/ethnicity, home languages, and special education status. Both discipline counts and severity were statistically associated with race/ethnicity, and gender, while special education status was significantly related only to discipline severity. In addition, classroom composition variables based on student and family demographics, and students’ prior year scores on the outcome were significantly related to student outcomes. These results suggest that student characteristics, contextual classroom composition variables arising from student backgrounds are more important in predicting student outcomes than teacher years of experience, at least in a mid-high poverty school district. Therefore, student placements might be a key to addressing educational inequity for high-need students in mid-high poverty schools, consistent with prior studies in high-poverty schools.

The production of “separate collections” (bieji 別集) or collected works in China is a social practice that emerged between the 1st and 3rd centuries CE. This research focuses on how the practice developed over the course of the Song dynasty (960-1279) in terms of literary materials involved, competences required, associated meanings, and its links to other social practices. I examine extant collected works, descriptions of them, and contemporary feedback on their production to create a series of snapshots that reveal its trajectory over time. Surveying the emergence of the practice in the early imperial period through its development in medieval times shows that pre-Song dynasty production of collected works was the result of several pre-existing conditions: competences related to bookmaking, the emergence of the idea of the inscription of authorial personality in literary works, the elevated status of belles-lettres, and several pre-existing tropes that lent it increasing importance. As the practice began recruiting scholars in 1020, it underwent a series of changes: attention to loss and variation between editions gave way to the search for missing works and the production of increasingly complete and authentic editions. This was followed in 1080 by several innovations, including the organization of works literary according to chronological order, rhyme, or topical category and insertion of annotations and a chronological biography. After 1180, compilers began synthesizing the accomplishments of previous editions to make editions that featured multiple annotators arranged in increasingly sophisticated ways for a new readership that were strongly associated with commercial printing. I identify six varieties of the production of the collected works of Song authors, each with distinct aims and associations that differed with respect to elements of practice, the practitioners they recruited, and how they linked with other social practices toward larger social goals. Findings contribute to Chinese book history by contextualizing change in formalistic trends over time. Identified as a social practice, the account of change and variation in the compilation of collected works during the Song presented in this research adds unique perspective to the subject of social change in this pivotal period of Chinese history.

This dissertation discusses how Confucianism was invented as the basis for culturalidentity of East Asia and how the “Confucian” Classics were circulated and translated in and beyond China proper. Penetrating the compelling forces behind four well-known and widely used texts—the Shijing, the Hanshu, the Shuowen jiezi, and the Erya—in relation to the power dynamics and negotiations among their writers and others in their times, this dissertation follows two tracks. The first investigates how the Classics—which were shared heritages in the pre-Han period (<202 B.C.E.)—became Confucian cultural capital, on the one hand, and how Confucius and his followers were described as authoritative transmitters of ancient culture and martyrs on orders from “anti-traditional” emperors (such as the China’s first Emperor, Qin Shihuangdi), on the other hand. These four early texts, therefore, set forth the framework within which later Confucian intellectuals studied the Classics and the ancient knowledge therein, and also understood their relationship with state power. The second track explores these texts’ Sinocentric and pedantic attitude toward the circulation of the Confucian Classics among people and cultural “Others” who lacked training in the archaic language of the Classics. Nowadays, in light of the fact that the Confucian Classics have become required texts in the curriculum of national learning in the People's Republic of China (PRC), this dissertation provides a lens through which one can see more clearly how Confucianism becomes part of nation building, even in the contemporary world.

Religions, following Max Müller, have often been seen by scholars in religious studies as uniform collections of beliefs and practices encoded in stable “sacred books” that direct the conduct of religious actors. These texts were the chief focus of academic students of religion through much of the 20th century, and this approach remains strong in the 21st. However, a growing chorus of dissidents has begun to focus on the lived experience of practitioners and the material objects that structure that experience, and some textual scholars have begun extending this materialist framework to the study of texts. This dissertation is a contribution in that vein from the field of Daoist studies. Now split between two separate texts, the Most High Scripture of the Rectifying Methods of the Three Heavens began as a 4th-century collection of apocalyptic predictions and apotropaic devices designed to deliver a select group of Chinese literati to the heavens of Highest Clarity. Later editors during the early medieval period (ca. 220-589 CE) took one of two paths: for their own reasons, they altered the Rectifying Methods to emphasize either the world’s end or its continuation. Detailed study of these alterations and their contexts shows how individuals and groups used and modified the Rectifying Methods in in ways that challenge the conventional relationship between religious text and religious actor.

This dissertation focuses on the corpus of Zang Maoxun’s literary creations in The Collection from the Fubao Hall and investigates his involvement in the cultural activities of the Jinling Poetry Society. Unearthing how Zang and this Society, as self and community, played an instrumental role in creating and sustaining a network of dramatists and drama critics in the Jiangnan region, a careful review of his poems and prose shows the extent to which text preparation, commentary, and printing were at the center of his communications with his social circle. Moreover, this dissertation unpacks Zang’s contribution to the promotion of dramatic texts through a thorough examination of his ardent editorial work in revising Tang Xianzu’s The Four Dream Plays from the Jade Tea Hall, the epitome of the southern musical drama. By using Zang’s 1618 Diaochong guan edition of his adaptations as a focal point, this dissertation compares it with three late Ming editions of Tang’s plays printed in the dual colors of red-and-black ink. In light of their innovative editorial designs, and the varying evaluations formed in their pages about Zang’s editorial work, this dissertation reveals the importance of Zang’s adaptations in the history of The Four Dream Plays’ textual transmission, as well as the interplay between the tradition of drama criticism and the new technology of multicolor printing and consequent innovation in editorial principles.

Teacher mobility is a policy issue that affects students and school across the country. Despite a long-standing body of research related to teacher mobility, relatively little is known about how teacher-school pairings affect teachers’ decisions to stay at or leave their schools. Therefore, this study tested a model of teacher-school fit with a focus on the value that teachers and principals place on standardized test scores. Survey responses were collected from 382 K-8th grade public school teachers from 22 schools in two school districts. The results show that teachers who placed higher values on standardized test scores reported slightly higher levels of teacher-school fit and were slightly less likely to leave their schools within five years. Additionally, teachers’ self-assessed teacher-school fit showed a strong, positive relationship with teacher retention. These findings suggest that a better understanding of the factors that affect teachers’ sense of teacher-school fit may help reduce teacher mobility.

This dissertation explores the history of ancestral rituals and the related political controversy in the Song China (960-1279). Considering the pivotal role played by ancestral rites in shaping Chinese identity and consciousness, this study contributes to a better understanding of how ancestral ritual has been politicized in Chinese history as a specific cultural apparatus to manipulate politics through theatrical performance and liturgical discussion. Through a contextual analysis of a variety of Song scholar-officials and their ritual writings, including memorials, private letters, and commentaries on the ritual Classics, this study demonstrates that Song ritual debates over the zhaomu 昭穆 sequence--that is, the positioning of ancestral temples and spirit tablets in ancestral temples with preparation for alternation or removal--differentiated scholar-officials into separate factions of revivalists, conventionalists and centrists. From a new perspective of ritual politics, this study reveals the discursiveness of the New Learning (xinxue新學) community and its profound influence on the Learning of the Way (Daoxue 道學) fellowship of the Southern Song (1127-1279). It examines the evolution of the New Learning fellowship as a dynamic process that involved internal tension and differentiation. Daoxue ritualism was a continuation of this process in partaking in the revivalist approach of ritual that was initiated by the New Learning circle. Nowadays, the proliferation of ritual and Classical studies crystallizes the revitalization of Confucianism and Confucian rituals in China. Taking zhaomu as a point of departure, this project provides a lens through which modern scholars can explore the persistent tension between knowledge and power by rethinking the modernization of ritual and ritual politics in contemporary China.

Methods to test hypotheses of mediated effects in the pretest-posttest control group design are understudied in the behavioral sciences (MacKinnon, 2008). Because many studies aim to answer questions about mediating processes in the pretest-posttest control group design, there is a need to determine which model is most appropriate to test hypotheses about mediating processes and what happens to estimates of the mediated effect when model assumptions are violated in this design. The goal of this project was to outline estimator characteristics of four longitudinal mediation models and the cross-sectional mediation model. Models were compared on type 1 error rates, statistical power, accuracy of confidence interval coverage, and bias of parameter estimates. Four traditional longitudinal models and the cross-sectional model were assessed. The four longitudinal models were analysis of covariance (ANCOVA) using pretest scores as a covariate, path analysis, difference scores, and residualized change scores. A Monte Carlo simulation study was conducted to evaluate the different models across a wide range of sample sizes and effect sizes. All models performed well in terms of type 1 error rates and the ANCOVA and path analysis models performed best in terms of bias and empirical power. The difference score, residualized change score, and cross-sectional models all performed well given certain conditions held about the pretest measures. These conditions and future directions are discussed.

In investigating mediating processes, researchers usually use randomized experiments and linear regression or structural equation modeling to determine if the treatment affects the hypothesized mediator and if the mediator affects the targeted outcome. However, randomizing the treatment will not yield accurate causal path estimates unless certain assumptions are satisfied. Since randomization of the mediator may not be plausible for most studies (i.e., the mediator status is not randomly assigned, but self-selected by participants), both the direct and indirect effects may be biased by confounding variables. The purpose of this dissertation is (1) to investigate the extent to which traditional mediation methods are affected by confounding variables and (2) to assess the statistical performance of several modern methods to address confounding variable effects in mediation analysis. This dissertation first reviewed the theoretical foundations of causal inference in statistical mediation analysis, modern statistical analysis for causal inference, and then described different methods to estimate causal direct and indirect effects in the presence of two post-treatment confounders. A large simulation study was designed to evaluate the extent to which ordinary regression and modern causal inference methods are able to obtain correct estimates of the direct and indirect effects when confounding variables that are present in the population are not included in the analysis. Five methods were compared in terms of bias, relative bias, mean square error, statistical power, Type I error rates, and confidence interval coverage to test how robust the methods are to the violation of the no unmeasured confounders assumption and confounder effect sizes. The methods explored were linear regression with adjustment, inverse propensity weighting, inverse propensity weighting with truncated weights, sequential g-estimation, and a doubly robust sequential g-estimation. Results showed that in estimating the direct and indirect effects, in general, sequential g-estimation performed the best in terms of bias, Type I error rates, power, and coverage across different confounder effect, direct effect, and sample sizes when all confounders were included in the estimation. When one of the two confounders were omitted from the estimation process, in general, none of the methods had acceptable relative bias in the simulation study. Omitting one of the confounders from estimation corresponded to the common case in mediation studies where no measure of a confounder is available but a confounder may affect the analysis. Failing to measure potential post-treatment confounder variables in a mediation model leads to biased estimates regardless of the analysis method used and emphasizes the importance of sensitivity analysis for causal mediation analysis.
