In this article, we review approaches to modeling a connection between spatial and mathematical thinking across development. We critically evaluate the strengths and weaknesses of factor analyses, meta-analyses, and experimental literatures. We examine those studies that set out to describe the nature and number of spatial and mathematical skills…

Measurement invariance of the Wechsler Intelligence Scale for Children--Fourth Edition (WISC-IV) was investigated with a group of 352 students eligible for psychoeducational evaluations tested, on average, 2.8 years apart. Configural, metric, and scalar invariance were found. However, the error variance of the Coding subtest was not constant…

Multiple-group confirmatory factor analysis (MG-CFA) is among the most productive extensions of structural equation modeling. Many researchers conducting cross-cultural or longitudinal studies are interested in testing for measurement and structural invariance. The aim of the present paper is to provide a tutorial in MG-CFA using the freely…

Objectives: To demonstrate how the bootstrap method could be conducted in exploratory factor analysis (EFA) with a syntax written in SPSS. Methods: The data obtained from the Texas Childhood Obesity Prevention Policy Evaluation project (T-COPPE project) were used for illustration. A 5-step procedure to conduct bootstrap factor analysis (BFA) was…

The purpose of this study was to develop a valid and reliable scale to identify the perception management tactics used by school administrators. For this purpose, a 42-item measurement tool, which was developed based on interviews with 6 School Principals, 11 Assistant Principals and 28 Teachers from different branches, was presented to eight…

Evidence of cultural comparisons of gender-identity-measurement scales is scarce. The present study aims to assess the scalar invariance of two dimensions of a widely used gender identity scale (Egan and Perry's Multidimensional Gender Identity Inventory) across two cultural contexts. Fourth, sixth, and fifth graders from Barranquilla (Colombia)…

This study investigated the dimensionality of bilingual phonological awareness (PA) in English and Spanish by replicating a kindergarten model in Grade 1, and presents alternatives to modeling clustered data. English and Spanish tasks were analyzed from previously collected samples totaling 1,586 first grade Spanish-speaking English learners. Four…

The Multidimensional Teacher Victimization Scale (MTVS) was developed to provide schools with a comprehensive and psychometrically sound self-report scale to assess teachers' perceptions of teacher-targeted aggressive and violent behaviors perpetrated by students. Using a cross-sectional survey-based research design, data were collected on a…

Educational organizations in institutionalized environments may try to reflect a legitimate image of the environment in their internal structure. However, there may be loosely coupled relationship between anticipated legitimacy and the performed actions in the schools. Thus, that lack of congruence between rhetoric and the behaviors constitutes…

This study investigates the effects of web-based scaffolding in comparison with teacher scaffolding (TS) and no scaffolding (NS) on students' metacognitive skill development in web-search process. The study utilized a static-group pretest--posttest quasi-experimental design. The first experimental group received web-based Internet search…

This quantitative study examines whether and to what extent affective factors (i.e. motivation, self-confidence, risk-taking, L2 speaking anxiety, and grit) and virtual intercultural experiences are linked to willingness to communicate in a second language (L2 WTC) in in-class, out-of-class, and digital settings. Participants included 176 Korean…

The internal/external (I/E) frame of reference entails high, positive association of mathematics and verbal achievements with matching academic self-concepts but negative or near-zero correlation with their nonmatching self-concepts. This study aimed to extend the traditional I/E model by contrasting the mathematics domain with two foreign…

Position effects may occur in both paper--pencil tests and computerized assessments when examinees respond to the same test items located in different positions on the test. To examine position effects in large-scale assessments, previous studies often used multilevel item response models within the generalized linear mixed modeling framework.…

All stake holders in competency based teacher training systems share an interest in the consistency of assessment outcomes and practice. Assessment data from more than 200 trainees participating in Initial Teacher Training/Education (ITT/E) programmes and partnerships at a Higher Education (HE) provider in the Northwest of England were analysed…

We examined the reliability, validity and factor structure of the Eye Contact Avoidance Scale (ECAS), a new 15-item screening tool designed to measure eye contact avoidance in individuals with fragile X syndrome (FXS). Internal consistency of the scale was acceptable to excellent and convergent validity with the Social Responsiveness Scale, Second…
