Many studies of organizations that employ the servant leadership model have been conducted, but there is a lack of empirical research on the relationship between servant leadership and staff job satisfaction in religious educational institutions that do not pay their staff. Therefore, a study of the correlation between servant leadership style,…

The objectives of this dissertation include describing and analyzing the patterns of inequality in ALE participation at both the micro and macro levels. Special attention is paid to social origins of individual adults and their association with two groups of macro-level factors, social inequality (income, education, and skill inequality) and…

It is a common knowledge that student achievement is a product of multiple individual and environmental factors. The literature developed various models to organize and explain the relationship between some of these variables and student learning which translates into student achievement. Yet, no comprehensive model is able to capture all possible…

Because results from TIMSS 2007 showed a gap in mathematics and science achievement between students in the United States and those in the top-performing countries, TIMSS 2007 data were used to investigate how school effectiveness factors known to be strongly associated with higher STEM achievement operated in the United States compared to Chinese…

School principals have a small to moderate influence on student achievement; however, this influence is largely indirect via the behaviors, beliefs, knowledge, practices, and competencies of their teachers. Despite a growing number of studies examining the indirect influence of school principals on student achievement, there is still much to know…

Nonlinear multilevel latent variable modeling has been suggested as an alternative to traditional hierarchical linear modeling to more properly handle measurement error and sampling error issues in contextual effects modeling. However, a nonlinear multilevel latent variable model requires significant computational effort because the estimation…

International mathematics assessments have established students in East Asia as among the best in the world and their U.S. counterparts as mediocre. What is not clear is why this "achievement gap" exists. The last major study to address this question, Stevenson and Stigler's (1992) "The Learning Gap," was published prior to…

Maximum likelihood (ML) estimation of generalized linear mixed models (GLMMs) is technically challenging because of the intractable likelihoods that involve high dimensional integrations over random effects. The problem is magnified when the random effects have a crossed design and thus the data cannot be reduced to small independent clusters. A…

This study examined the multilevel factors that influence mathematics and English performance on the Primary Leaving Examinations (PLEs) among primary seven pupils (i.e., equivalent to the United States [U.S.] 7th graders) in Uganda. Existing student state test data from the Wakiso District were obtained. In addition, a newly created Teacher…
