Previous empirical studies have shown that information along visual contours is known to be concentrated in regions of high magnitude of curvature, and, for closed contours, segments of negative curvature (i.e., concave segments) carry greater perceptual relevance than corresponding regions of positive curvature (i.e., convex segments). Lately,…

"Methods and Procedures in PIRLS 2016" documents the development of the Progress in International Reading Literacy Study (PIRLS) assessments and questionnaires and describes the methods used in sampling, translation verification, data collection, database construction, and the construction of the achievement and context questionnaire…

Due to the growing importance of the professional role of teachers, effective evaluation practices are essential to ensuring highly qualified educators. The problem addressed was how Volusia County School teachers in the state of Florida experienced the teacher evaluation process and how that impacted the effectiveness of instructional practices…

The main purpose of this study is to improve estimation efficiency in obtaining maximum marginal likelihood estimates of contextual effects in the framework of nonlinear multilevel latent variable model by adopting the Metropolis-Hastings Robbins-Monro algorithm (MH-RM). Results indicate that the MH-RM algorithm can produce estimates and standard…

Problem Statement: Today, immobility and resulting weight gain constitutes one of the greatest problems among young people. The greatest problem for individuals spending a lot of time on the Internet is immobility. The result of this status is spending less energy than the amount required daily. Immobility is considered a cause of being…

Evidence-based practices (EBPs) are supported as generally effective for populations of learners by bodies of high-quality and experimental research and, when aligned with stakeholder values and practical needs, should be prioritized for implementation. However, evidence-based practices are not currently available for all learner types in all…

Cognitive Diagnostic Models (CDMs) aim to provide information about the degree to which individuals have mastered specific attributes that underlie the success of these individuals on test items. The Q-matrix is a key element in the application of CDMs, because contains links item-attributes representing the cognitive structure proposed for solve…

The need to understand the settings in which students drink represents an ongoing challenge for universities. Undergraduate students (N = 2,146) completed an online multicampus survey to capture the perceptions of off-campus party guests regarding common party behaviors and events.

The study was conducted in order to detect critical thinking dispositions and learning styles of the students of school of physical education and sports, to explore whether there was a significant difference in terms of gender variable and academic department variable and, to discover the correlation between critical thinking tendencies and…

A multilevel meta-analysis can combine the results of several single-subject experimental design studies. However, the estimated effects are biased if the effect sizes are standardized and the number of measurement occasions is small. In this study, the authors investigated 4 approaches to correct for this bias. First, the standardized effect…

Transitions are a critical time for executives at all types of higher education institutions. Some vice presidents for student affairs sail through the transition period, while others stumble because they could not navigate the complexity of the new role. Vice presidents who appropriately match their leadership and management style to the new…

This dissertation performed an investigation of the psychometric properties of six instruments used in the 2012 Happiness Project research study. The project revisited the 2010 study conducted by Holder, Coleman, and Wallace. Holder et al. (2010) investigated the relationships among variables relating to student happiness and spirituality while…

The main purpose of this study is to improve estimation efficiency in obtaining maximum marginal likelihood estimates of contextual effects in the framework of nonlinear multilevel latent variable model by adopting the Metropolis-Hastings Robbins-Monro algorithm (MH-RM; Cai, 2008, 2010a, 2010b). Results indicate that the MH-RM algorithm can…
