The "Psychological Sense of School Membership" (PSSM) scale has been used for more than 20 years to measure students' sense of school belonging, yet its psychometric properties have had limited examination with pre-adolescent children. This study investigated the utility and psychometrics of the PSSM in three primary school samples from…

The purpose of this study was to examine the psychometric properties of the "Autism Program Environment Rating Scale" ("APERS"), an instrument designed to assess quality of program environments for students with autism spectrum disorder. Data sets from two samples of public school programs that provided services to children and…

This study describes the development and initial psychometric evaluation of a Recognizing Effective Special Education Teachers (RESET) teacher observation instrument. Specifically, the study uses generalizability theory to compare two versions of a rubric, one with general descriptors of performance levels and one with item-specific descriptors of…

The Strengths and Difficulties Questionnaire (SDQ) self-report form is a brief 25-item measure that assesses the psychological adjustment of youth. Although widely utilized as a screening tool, a lack of consistent psychometric evidence undermines the SDQ's utility as a sound diagnostic tool for all youth. This study focused on examining the…

The purpose of this study was to identify the factor structure of the Child Oral and Motor Proficiency Scale (ChOMPS) and to evaluate the psychometric properties, including internal consistency reliability, test-retest reliability, and construct validity as measured by convergent and known-groups validity. Principal component analysis with varimax…

In this study, the replicability of the factor structure of The School Liking and Avoidance Questionnaire [SLAQ] for Turkish preschool children and the psychometric properties of the scale were investigated. The SLAQ consists of 14 items and is used to assess children's emotional and behavioral participation in school based on children's…

Drawing valid inferences from modern measurement models is contingent upon a good fit of the data to the model. Violations of model-data fit have numerous consequences, limiting the usefulness and applicability of the model. As Bayesian estimation is becoming more common, understanding the Bayesian approaches for evaluating model-data fit models…

This study established a Chinese scale for measuring high school students' ocean literacy. This included testing its reliability, validity, and differential item functioning (DIF) with the aim of compensating for the lack of DIF tests focusing on current scales. The construct validity and reliability were verified and tested by analyzing the…

This article describes the development, initial validation, and psychometric evaluation of the mathematical modeling attitude scale (MMAS). Specifically, both qualitative and quantitative techniques were used to generate relevant items. The MMAS assesses K-12 teachers' attitude toward mathematical modeling and examines their experiences with…

Aim(s): School belonging is critically important for both school-based outcomes and psychosocial adjustment of adolescents. The purpose of this study is to present further validation evidence for the School Belongingness Scale (SBS) and investigate the predictive effect of the school belonging on school achievement and mental health outcomes (i.e.…

Current taxonomies of intelligence comprise two factors of mental speed, clerical speed (Gs), and elementary cognitive speed (Gt). Both originated from different research traditions and are conceptualized as dissociable constructs in current taxonomies. However, previous research suggests that tasks of one category can be transferred into the…

We review recent research about the development of creativity in South America focusing on studies of individual differences in creativity and educational and developmental studies of children and adolescents' creativity. Most South American researchers are influenced by mainstream psychometric approaches, although computational and cultural…

The aim of this study was to test the gender invariance of the Chinese version of the Achievement Goal Questionnaire (AGQ-C) utilizing a sample of 1,115 Chinese university students. Multi-group confirmatory factor analysis supported the configural, metric, and scalar invariance of the AGQ-C across genders. Analyses also revealed that the latent…

This report presents results on a parallel implementation of the expectation-maximization (EM) algorithm for multidimensional latent variable models. The developments presented here are based on code that parallelizes both the E step and the M step of the parallel-E parallel-M algorithm. Examples presented in this report include item response…

In recent years, substantial improvements were obtained in the effectiveness of data driven algorithms to validate the mapping of items to skills, or the Q-matrix. In the current study we use ensemble algorithms on top of existing Q-matrix refinement algorithms to improve their performance. We combine the boosting technique with a decision tree.…
