Mediation analysis is an important statistical tool in many research fields, where the joint significance test is widely utilized for examining mediation effects. Nevertheless, the limitation of this mediation testing method stems from its conservative Type I error, which reduces its statistical power and imposes certain constraints on its…

Recent research on achievement in science asserts that motivation, emotion, and metacognition are important driving forces for learning. This study sought to examine the relationships between two physics class emotions (hope and anxiety), their motivational predictors (instrumentality and self-efficacy), and their effects on metacognitive problem…

In this study, we provide a contemporary examination of the similarities and differences between early childhood general educators (ECEs) and early childhood special educators (ECSEs) within a theoretically driven model that accounted for the associations of beliefs and knowledge with practice. We used structural equation modeling to examine the…

This study compared student engagement and achievement levels between students enrolled in a traditional college algebra lecture course and students enrolled in a "flipped" course. Results showed that students in the flipped class had consistently higher levels of achievement throughout the course than did students in the traditional…

Interaction and quadratic effects in latent variable models have to date only rarely been tested in practice. Traditional product indicator approaches need to create product indicators (e.g., x[superscript 2] [subscript 1], x[subscript 1]x[subscript 4]) to serve as indicators of each nonlinear latent construct. These approaches require the use of…

Based on Astin's (1993) theory of involvement and Astin's (1991) college impact model a model of college student leader development was developed to examine the process of leader development among students who participated in sport during college. In addition, the differences between students who participated in different levels of sport…

School leadership has been shown to exert a positive but mostly indirect influence on school and student outcomes. Currently, there is great interest in how quality leadership preparation is related to leadership practice and improved teacher outcomes. The purpose of the study was to understand the moderating influence of leadership preparation on…

Background: The prevalence of obesity among high school students has risen in recent decades. Many high school students report trying to lose weight and some engage in disordered eating to do so. The obesity proneness model suggests that parents may influence their offspring's development of disordered eating. This study examined the viability of…

This exploratory study examined the influences of student, teacher, and setting characteristics on kindergarteners' early reading outcomes and investigated whether those relations were moderated by type of intervention. Participants included 206 kindergarteners identified as at risk for reading difficulties and randomly assigned to one of two…

A theory-driven approach to evaluation (TDE) emphasizes the development and empirical testing of conceptual models to understand the processes and mechanisms through which programs achieve their intended goals. However, most reported applications of TDE are limited to large-scale experimental/quasi-experimental program evaluation designs. Very few…

The purpose of this study was to (a) determine the extent to which Latina/o students' perceptions of support from high school teachers and counselors, as well as acculturation, predict enrollment in AP coursework; (b) examine Latina/o students' perceptions of different forms of support that appear to play a role in academic success (Hassinger…

The purpose of this study was to determine if the frequent use of LanguageLinks: Syntax Assessment and Intervention (LL), produced by Laureate Learning Systems, Inc., as a supplemental classroom activity, affected morphosyntax structures (determiners, tense, and complementizers) in participants who are Deaf/Hard of Hearing (DHH) and use American…
