Measures of academic engagement and disruptive behavior in students are strong predictors of social, academic, and lifelong career outcomes. Educators need a measurement tool that is feasible, accurate, and cost-effective in order to identify students who may be in need of additional behavioral support. Direct Behavior Ratings (DBRs) offer a…

The aim of this study is to compare the results of correlation coefficient estimation of reliability with those obtained through the Bland-Altman plot technique. The scale was first divided into two halves using three different approaches. A linear and high-level relationship was found between the scale scores obtained from the halved forms.…

The goal of this study was to advance the conceptualization and measurement of adolescent popularity by exploring the commonly used composite score (popularity minus unpopularity). We used standardized peer nominations from 4,414 early adolescents (ages [approximately equal to] 12-14 years) from three samples collected in two countries. Popularity…

The importance of improving teachers' use of culturally responsive practice (CRP) in the classroom setting has been widely recognized. Although quantitative data on teachers' use of CRP has potential to be a helpful decision-making tool in advancing that goal, little is known about the psychometrics of classroom-based CRP measures, their utility…

The purpose of this study was to adapt the Expectancy Value Scale, Students' Motivation for Homework Scale, Homework Interest Scale, Homework Affective Attitude Scale, Math Homework Purposes Scale into Turkish and to develop the Homework Self Efficacy Scale. 1555 middle school students of 5th and 8th grades participated in the study. The students…

The present article describes the development and validation of the Informational and Normative Conformity Scale (SKI-N), a brief self-report tool capturing adolescents' general propensity to adopt a conformist attitude, and the underlying motives for doing so. The presentation includes a description of scale construction and an assessment of the…

The teaching and learning of quantum physics has recently become a topic of increasing interest in physics education research. In particular, the study of two-state systems is gaining importance as a means of teaching quantum physics at various educational levels. Meanwhile, a number of approaches have been developed that are also suitable for…

Childhood social and emotional competencies are recognized as teachable skills affecting well-being and developmental outcomes across the life span. This study sought to develop and validate a brief self-report measure of social-emotional competencies in middle childhood. The study used items from the 2015 Middle Childhood Survey, administered to…

Assessing students' conceptions related to independence of events and determining probabilities from a sample space has been the focus of research in probability education for over 40 years. While we know a lot from past studies about predictable ways students may reason with well-known tasks, developing a diagnostic assessment that can be used by…

Measurement of mental rotation presents a serious challenge to cognitive researchers owing to the lack of a single comprehensive measure that can be applied across the developing age groups. Objective of the present study was to develop and validate a new measure of mental rotation for preadolescent and adolescent age groups. Items were…

This article examined the psychometric properties and validity of a new self-report instrument for assessing the social norms that coordinate social relations and define self-worth within three normative systems. A survey that assesses endorsement of honor, face, and dignity norms was evaluated in ethnically diverse adolescent samples in the U.S.…

Students with learning disabilities (LD) represent a vulnerable population and are at higher risk for social and emotional challenges compared to their peers without LD. A strengths-based orientation is recommended to encourage building resilience factors to counteract the negative effects of LD over the lifespan. To identify areas of strength and…

We tested the reliability and construct validity of a Chinese translation of one of the forms of the Behavior Assessment System for Children (3rd Edition)--Self-Report of Personality for adolescent 11- to 21-year olds (BASC-3-SRP-A). The BASC-3-SRP-A yields 16 subscales that form four composite scales. Data were obtained from 444 12- to 14-year…

School bullying is a significant public health problem and a widespread type of school violence. Empirically validated evaluation scales are needed for use in research and practice to explain the nature and scope of adolescent bullying. The current study investigated the multilevel factor structure and measurement invariance of the Olweus…
