This study examined the psychometric properties of the Positive and Negative Affect Schedule for Children-Short Form (PANAS-C-SF) in a diverse sample of 15-year-olds in the United States [N = 4382]. Multiple measurement models, including a one-factor model, two-factor orthogonal and oblique models, a three-factor model (PA, Fear, and Distress),…

This study aimed to develop a comprehensive tool to assess underachievement in gifted students, incorporating input from parents, teachers, and students themselves. A total of 285 participants, including 95 gifted students, their parents, and teachers, were involved in the study. The results have revealed a four-factor structure for the Gifted…

The Kaufman Test of Educational Achievement, 3rd edition (KTEA-3) is a popular battery for the assessment of students' academic skills. Its manual includes a series of confirmatory factor analyses to support construct validity. Its five-factor model did not include all available subtests in the battery and required covarying residuals between…

The Woodcock-Johnson Tests of Achievement, Fourth Edition (WJ IV ACH) is purported to align with Cattell-Horn-Carroll (CHC) theory and offers upward of 20 scores within its interpretive and scoring system. The Technical Manual does not furnish validity evidence for the scores reported by the scoring system, suggesting that evidentiary support may…

The Wechsler individual achievement test, third edition (WIAT-III) is a popular individually administered achievement battery. Despite its ubiquity in assessment practice, scant research into its structure exists. We analyzed the structure of the WIAT-III in a sample of students in Grades 3-12 referred for special education evaluations (n = 355).…

The purpose of this research is to examine measurement invariance of collaborative problem solving skills measured by PISA 2015 Xandar subtest for Singapore, Norway, and Turkey. The research was conducted with 2990 participants' data obtained from Turkey (1032), Norway (923), and Singapore (1035) on PISA 2015 collaborative problem solving study.…

International surveys are increasingly being used to understand nonacademic outcomes like math and science motivation, and to inform education policy changes within countries. Such instruments assume that the measure works consistently across countries, ethnicities, and languages--that is, they assume measurement invariance. While studies have…

Theories of reading and writing development suggest that the factor structure of achievement batteries could change across development. As a result, it is important to test achievement batteries for invariance across development. The purpose of these analyses is to determine whether the factor structure of reading, writing, and oral language…

The present study examines the measurement property of instructional quality in mathematics education, building on data from teachers and students, by combing TALIS 2013 and PISA 2012 linkage data from seven countries. Confirmatory factor analysis was applied to examine the dimensionality of the construct instructional quality in mathematics…

The aim of the study is to develop an achievement test consisting of the questions in verbal intelligence games whose validity and reliability have been ensured and which are in accordance with the learning outcomes of the states of substance and knowing the properties of substance via the five senses taking place in the unit "Let's Know…

Given the ongoing development of computer-based tasks, there has been increasing interest in modelling students' behaviour indicators from log file data with contextual variables collected via questionnaires. In this work, we apply a latent regression model to analyse the relationship between latent constructs (i.e., performance, speed, and…

The authors evaluated measurement-level, factor-level, item-level, and scale-level revisions to the "Gifted Rating Scales-School Form" (GRS-S). Measurement-level considerations tested the extent to which treating the Likert-type scale rating as categorical or continuous produced different fit across unidimensional, correlated trait, and…

In the current study, we aimed to develop a reliable and valid scale to address individual cognitive load types. Existing scale development studies involved limited number of items without adequate convergent, discriminant and criterion validity checks. Through a multistep correlational study, we proposed a three-factor scale with 13 items to…

To better understand the writing skills of juvenile offenders and the components of their writing abilities, this study explored extant data from six measures of adolescents' writing skills administered upon their entrance into a juvenile justice facility. Overall, the 235 students (ages 13-16; Grades 5-11) exhibited low scores on all writing…

The "GRE"® Psychology test is an achievement test that measures core knowledge in 12 content domains that represent the courses commonly offered at the undergraduate level. Currently, a total score and 2 subscores, experimental and social, are reported to test takers as well as graduate institutions. However, the American Psychological…
