Parameter recovery was assessed within mixture confirmatory factor analysis across multiple estimator conditions under different simulated levels of mixture class separation. Mixture class separation was defined in the measurement model (through factor loadings) and the structural model (through factor variances). Maximum likelihood (ML) via the…

Background/Context: Little research has directly examined whether principal leadership can increase the degree to which teachers work together regularly in focused ways around content. Prior research has shown that reform efforts seeking to alter the process of teaching can be successful if teachers collaborate to build capacity and improve…

Of the several measures of optimism presently available in the literature, the Life Orientation Test (LOT; Scheier & Carver, 1985) has been the most widely used in empirical research. This article explores, confirms, and cross-validates the factor structure of the Chinese version of the LOT with ordinal data by using robust weighted least…

Multiple linear regression and ANOVA models are widely used in applications since they provide effective statistical tools for assessing the relationship between a continuous dependent variable and several predictors. However these models rely heavily on linearity and normality assumptions and they do not accommodate categorical dependent…

Teachers are the primary agents for creating and maintaining a positive classroom climate--and promoting healthy interpersonal relations with, and among, their students (including the prevention of school bullying) is key to achieving this goal. For this study it was posited that students' willingness to report bullying to their teachers is an…

A scale was developed to measure perceptions of sexual abuse in youth sports by assessing (a) the perceived prevalence of sexual abuse committed by pedophilic youth sport coaches, (b) the perceived likelihood that a coach is a pedophile, (c) perceptions on how youth sport organizations should manage the risk of pedophilia, and (d) media influence…

The Epistemic Beliefs Inventory (EBI), as a theory-based and empirically validated instrument, was originally developed and widely used in the North American context. Through a strict translation procedure the authors translated the EBI into Chinese, and then administered it to 451 students in 7 universities in mainland China. The construct…

This paper presents a structural equation modelling (SEM) approach for blended synchronous teacher training workshop. It examines the relationship among various factors that influence the Satisfaction (SAT) of participating teachers. Data were collected with the help of a questionnaire from about 500 engineering college teachers. These teachers…

A latent variable modeling approach for examining population similarities and differences in observed variable relationship and mean indexes in incomplete data sets is discussed. The method is based on the full information maximum likelihood procedure of model fitting and parameter estimation. The procedure can be employed to test group identities…

A Metropolis-Hastings Robbins-Monro (MH-RM) algorithm for high-dimensional maximum marginal likelihood exploratory item factor analysis is proposed. The sequence of estimates from the MH-RM algorithm converges with probability one to the maximum likelihood solution. Details on the computer implementation of this algorithm are provided. The…

In the present study the longitudinal relations between quantity of centre-based child care (in months) and teacher reports of internalising and externalising behaviour in the first and second grades were examined for 325 Slovenian children. The socio-political context of affordable, accessible and homogenously high-quality child care is quite…

Despite potential applications to educational contexts, the working alliance concept has largely been confined to psychotherapy intervention research. Some have explored theoretically related concepts (e.g., immediacy, rapport), but no measure currently exists of the working alliance between a teacher and student within an academic course. The aim…

In the structural equation modeling literature, the normal-distribution-based maximum likelihood (ML) method is most widely used, partly because the resulting estimator is claimed to be asymptotically unbiased and most efficient. However, this may not hold when data deviate from normal distribution. Outlying cases or nonnormally distributed data,…

The purpose of this study was to examine the underlying structure of the second edition of the Test of Gross Motor Development-2 (Ulrich, 2000) as applied to Chinese children. The Test of Gross Motor Development-2 was administered to 626 Hong Kong Chinese children. The outlier test with standard scoring was utilized. After data screening, a total…

Microblogging social networks (µBSNs) provide the opportunity to communicate worldwide while using a small number of characters; this is an apparent limitation that forces users to share only essential information when linking to the world with which they interact. These platforms can serve to motivate students by narrowing the physical and…
