Prior research has documented a general decline in children's learning value and self-concept (i.e., expectation for success), beginning in the first years of school. Students who demonstrated patterns of low academic value and low...
Multivariate meta-analysis methods typically assume the dependence of effect sizes. One type of experimental-design study that generates dependent effect sizes is the multiple-endpoint study. While the generalized least squares (GLS)...
Aging is associated with a decline in cognitive and psychomotor functions, resulting in difficulties with daily activities such as driving. Cognitive function has been found to be associated with arterial stiffening. These age-related...
It is beneficial for Chinese English-learners to improve their communicative competence through being taught in a communicative-based class (especially with the use of task-based language teaching, Nuevo, 2006). However, previous studies...

A Path Analysis of the Relationships among Mindsets, Academic Writing Anxiety, and Self-Satisfaction with Academic Writing of Chinese Graduate Students
Extant literature indicates that Chinese graduate students experience academic writing anxiety when writing with English as their second language (Cheng, 2014b; Ho, 2016; Huang, 2014; Liang & Turner, 2021). Writing anxiety exerts...
Meta-analytic techniques have gained great attention in educational, social and behavioral sciences to synthesize and summarize related study results. Most common tradition is to use primary studies with similar designs (correlational or...

In this dissertation, a DIF detection method for testlet-based data was developed and evaluated. The proposed DIF model is an extension of a bi-factor multidimensional IRT model for testlets. Unlike other IRT-based DIF detection models, ...
This dissertation proposes an approach for synthesizing the Mantel-Haenszel (MH) Differential Item Functioning (DIF) index. It is shown that meta-analytic summaries of MH DIF estimates have potential implications for test development...
Many studies have been conducted to evaluate the performance of DIF detection methods, when two groups have different ability distributions. Such studies typically have demonstrated factors that are associated with inflation of Type I...
Elementary school children with academic challenges are often provided special education services. These services are meant to support children in their academic goals, through either academic intervention (e.g., reading or math) or...
A Structural Equation Modeling Analysis of Chinese Undergraduate English Language-Learners' Personal Factors and Contextual Factors Based on Self-Determination Theory
This study investigated the relationships among Chinese undergraduate English learners' motivation for learning English (i.e., students' internal choice, students' external pressure), integrative orientation (i.e., students' engagement...
The Comparison of Standard Error Methods in the Marginal Maximum Likelihood Estimation of the Two-Parameter Logistic Item Response Model When the Distribution of the Latent Trait Is Nonnormal
A Monte Carlo simulation study was conducted to investigate the accuracy of several item parameter standard error (SE) estimation methods in item response theory (IRT) when the marginal maximum likelihood (MML) estimation method was used...
Since Schommer first introduced a survey-approach to assess students' personal epistemology, there has been a proliferation of quantitative research on this topic area. Unfortunately, most of the previous studies did not differentiate...
Deane (2011) proposed a multi-layer cognitive writing model. The 2009 Cognitively Based Assessment of, for, and as learning (CBAL) Writing pilot assessment was designed to support that multi-layer model of writing. One of the features of...
While strategic self-talk interventions' positive effects on sport performance and performance-related processes are well documented, little is known regarding naturally occurring self-statements, or organic self-talk. Previously, eight...
In research synthesis, researchers may aim at summarizing peoples' attitudes and perceptions of phenomena that have been assessed using different measures. Self-report rating scales are among the most commonly used measurement tools to...
This research investigated freshman college students' motivation beliefs and motivation regulation strategies (to manage their effort and persistence) in the context of an authentic college-level academic task such as studying for an...
SES related differences in children’s early language skills influence their later language development. Parent-child verbal interactions during the initial years of children’s life play an important role in children’s early language...
Cultural capital is a key term from the Social Reproduction Theory, and it is defined as the codes and practices that parents pass on to their children (Bourdieu, 1984). Previous empirical studies have confirmed the importance of...
The Impact of Unbalanced Designs on the Performance of Parametric and Nonparametric DIF Procedures: A Comparison of Mantel Haenszel, Logistic Regression, SIBTEST, and IRTLR Procedures
The current study examined the impact of unbalanced sample sizes between focal and reference groups on the Type I error rates and DIF detection rates (power) of five DIF procedures (MH, LR, general IRTLR, IRTLR-b, and SIBTEST). Five...
Sport officials represent a ‘third team’ in sports that have the potential to change the outcome of games, seasons, and careers. The existing research on officials is sparse and disjointed with many studies going uncited as their...
The process of evaluating teachers has existed for many years and in a myriad of designs. Teacher evaluations are often a rating of instruction in a single observation. Teachers and other stakeholders strive to ensure that students are...
A new approach to representing data from multiple regression designs is presented in this dissertation. The index, denoted as rsp, is the semi-partial correlation of the predictor with the outcome of interest. This effect size can be...
Primary studies are using complex models more and more. Slopes from multiple regression analyses are reported in primary studies, but few scholars have dealt with how to combine multiple regression slopes. One of the problems in...
