The Modeling Self-Efficacy Scale was developed to measure students' confidence in understanding and solving modeling tasks. The scale was administered to 225 eighth- and ninth-grade students. Participants read modeling tasks adapted from Programme for International Student Assessment's 2003 problem-solving assessment and rated their confidence on…

Objectives: Despite advances in understanding associations among attention-deficit hyperactivity disorder (ADHD), emotion dysregulation (ED), and related outcomes, there is incongruity between ADHD-relevant conceptualizations of ED and available measures of ED. To assess the psychometric properties of a parent-report questionnaire of ED…

Aim: To evaluate the psychometric properties of a new measure of school belonging. Rationale: The sense of belonging to the school (organisation) as opposed to individuals within a school (peers) plays a significant part in pupils' behaviour and wellbeing. To date, few psychometrically robust, theoretically driven and brief scales exist.…

The present study assesses the factor structure, psychometric adequacy, and invariance across sex and age of the Relational Provisions Loneliness Questionnaire (RPLQ). Discriminant validity with an external criterion was also tested. In a sample of Portuguese adolescents, from 7th to 9th grade (N = 817), Confirmatory Factor Analyses (CFA) were…

This study evaluates a 12-item instrument for subjective measurement of mental load (ML) and mental effort (ME) by analysing different sources of validity evidence. The findings of an expert judgement (N = 8) provide "evidence based on test content" that the formulation of the items corresponds to the meaning of ML and ME. An empirical…

The purpose of this report is to describe the technical qualities of the 2018-2019 operational administration of the English language arts/literacy (ELA/L) and mathematics summative assessments in grades 3 through 8 and high school. The ELA/L assessments focus on reading and comprehending a range of sufficiently complex texts independently and…

The purpose of this report is to describe the technical qualities of the 2018-2019 operational administration of the English language arts/literacy (ELA/L) and mathematics assessments in grades 3 through 8 and high school. New Meridian, in coordination with multiple states and vendors, developed an alternate form of the summative assessment to…

In two studies (ns = 312 and 1,149) with 9- to 12-grade students in pre-International Baccalaureate (IB) and IB Diploma programs, we evaluated the reliability, factor structure, measurement invariance, and criterion-related validity of the scores from the School Attitude Assessment Survey-Revised (SAAS-R). Reliabilities of the five SAAS-R subscale…

In two studies (ns = 312 and 1149) with 9-12 grade students in pre-International Baccalaureate (IB) and IB Diploma programs, we evaluated the reliability, factor structure, measurement invariance, and criterion-related validity of the scores from the School Attitude Assessment Survey-Revised (SAAS-R; McCoach & Siegle, 2003a). Reliabilities of…

The authors aimed to propose a valid and reliable diagnostic instrument by developing a three-tier test on simple electric circuits. Based on findings from the interviews, open-ended questions, and the related literature, the test was developed and administered to 124 high school students. In addition to some qualitative techniques for…

Self-determination theory provides an integrated conception of school- and academic motivation. The theory proposes a continuum comprising three types of motivation: intrinsic motivation (IM), extrinsic motivation (EM), and amotivation (AM), characterised by seven dimensions (IM = to know, to accomplish and to experience stimulation, EM = external…

This study is a means of validating the Harter's Social Support Scale for Children on a sample of Mexican and Mexican American ninth-grade students to assist researchers and practitioners to more accurately assess this variable on this specific Latino group. The psychometric information was obtained through intercorrelations and Cronbach's alpha.…

In this study, the Resilience Scale for Adolescents (READ) was developed with confirmatory factor analysis and cross-validated factor model. The results show that the READ has sound psychometric qualities and that it measures all the central aspects of the psychological construct of resiliency. (Contains 4 tables.)

The purposes of this study were to: (1) examine the psychometric properties of the Ball Aptitude Battery (BAB) on a high school freshman sample; (2) develop BAB norms for high school freshmen; (3) develop and evaluate four memory tests and a vocabulary test appropriate for freshmen; (4) examine level and structure differences for the BAB tests…
