As multi/plurilingual research advances understandings of plurilingual speakers' fluid language use, particularly in multilingual settings, new research methods and pedagogical orientations that address this complex phenomenon are needed. The present study considered the development, reliability, and validity of the Plurilingual and Pluricultural…

The objectives were to examine the factorial structure of the Academic Procrastination Scale-Short Form (APS-S) and the measurement invariance across gender and educational levels, to determine possible differences in procrastination across gender, educational levels, and grades. The sample was formed of 1486 Spanish primary and secondary school…

Intercultural Teaching Competence (ITC) is essential for teaching in increasingly diverse primary schools. However, research has not sufficiently addressed the meaning and development of ITC, including whether study abroad during teacher education contributes to the dimensions included. Therefore, this study seeks to determine which dimensions of…

The purpose of this study is to develop Education Value Perception Scale (EVPS) based on Bronfenbrenner's Ecological Theory and to investigate its psychometric properties according to Classical Test Theory (CTT) and Item Response Theory (IRT). The data were collected from 2872 secondary school students by stratified purposeful sampling method.…

This study introduces the signal weighted teacher value-added model (SW VAM), a value-added model that weights student-level observations based on each student's capacity to signal their assigned teacher's quality. Specifically, the model leverages the repeated appearance of a given student to estimate student reliability and sensitivity…

Much of the science reported in the media depends on correlation coefficients. But the size of correlation coefficients depends, in part, on the reliability with which the correlated variables are measured. Understanding this is a statistical literacy issue.

Raters must score accurately and consistently for classroom observation scores to be valid. This requires (a) a standard defining when scoring is accurate and consistent enough and (b) measuring and remediating rater performance against that standard. Current practice has focused on this second problem to the exclusion of the first. My goal here…

From a theoretical perspective, most discussions of statistical learning (SL) have focused on the possible "statistical" properties that are the object of learning. Much less attention has been given to defining what "learning" is in the context of "statistical learning." One major difficulty is that SL research has…

The patterns of cumulated structured volleyball practice and other structured sports activities of elite adult Brazilian players, considering age of specialization in volleyball and achievement of international competition representing the national team, were examined using Bayesian multilevel models. Elite volleyball players (n = 78) with an…

A total of 248 students from one Southeastern U.S. middle school responded to measures of global and domain-based life satisfaction on three occasions, reflecting 5-month, 7-month, and 1-year time intervals. Alpha coefficients were all above 0.80 for each global and domain-based score on each occasion. The test--retest coefficients were variable,…

The high level of attrition and low rate of certification in Massive Open Online Courses (MOOCs) has prompted a great deal of research. Prior researchers have focused on predicting dropout based upon behavioral features such as student confusion, clickstream patterns, and social interactions. However, few studies have focused on combining student…

Network meta-analysis (NMA) combines direct and indirect evidence comparing more than 2 treatments. Inconsistency arises when these 2 information sources differ. Previous work focuses on inconsistency detection, but little has been done on how to proceed after identifying inconsistency. The key issue is whether inconsistency changes an NMA's…

Introduction: Given that people rely heavily on their party affiliation to make their political decisions, an interesting dilemma occurs when people are exposed to counter-attitudinal information from the party they identify with. This paper examines how exposure to counter-attitudinal messages from the party an individual identifies with…

Research Findings: The present study provides an initial descriptive comparison of the Early Childhood Environment Rating Scale-Revised (ECERS-R) and the Early Childhood Environment Rating Scale-Third Edition (ECERS-3) in a relatively large sample in 1 state that uses the Environment Rating Scales within its Quality Rating and Improvement System…

The aim of this study was to develop a continuous professional development training module based on multicultural counselling competency for professional counsellors in Malaysia. The research methodology comprised three phases: (i) training need assessment using survey method, (ii) module design and development and (iii) module evaluation using an…
