The purpose of this synthesis study was to assess the reliability and validity of the Draw-A-Scientist Test (DAST) and its variations across multiple studies, aiming to understand limitations and propose modifications for future application within and beyond the science domain. Given the existence of multiple DAST versions, this study quantified…

The aim of this study was to initially validate the REDFLAGS model, 8 cautionary warning signs of mental distress in college students. A test of internal consistency reliability and factor analysis supported the model's reliability and construct validity. Hierarchical logistic regression models endorsed the model's predictive validity; students'…

The aim of this study is to adapt the Statistics Anxiety Scale (SAS) developed by Vigil-Colet et al. (2008) to Turkish. This study is expected to fill an important gap in the literature since no valid and reliable specific statistics anxiety scale developed or adapted in Turkish for undergraduate students in the literature is available. The sample…

Much of the research that has examined the writing knowledge of school-age students has relied on interviews to ascertain this information, which is problematic because interviews may underestimate breadth and depth of writing knowledge, require lengthy interactions with participants, and do not permit a direct evaluation of a prescribed array of…

Grit--"perseverance and passion for long-term goals" (Duckworth, Peterson, Matthews, & Kelly, 2007, p. 1087)--has attracted the attention of researchers in fields ranging from psychology to business to education (e.g., Robertson-Kraft & Duckworth, 2014; Robins, 2019). Continuing the line of research that explores the domain…

Instruments for assessing secondary students' conceptual understanding of core concepts in biology are needed by educational practitioners and researchers alike. Most instruments available for secondary biology (years 9 to 12) focus only on highly specific biological concepts instead of multiple core concepts. This study describes the development…

"Research Findings": The Problematic Media Use Measure (PMUM) assesses young children's excessive or problematic media use. The current study aims to translate the original English version of PMUM into a Chinese version and validate it with Chinese preschoolers (ages 3 to 6). The instrument was translated, back-translated, pretested, and…

The present study aimed to empirically examine the validity of grit among language learners and its relation to vocabulary knowledge. Grit is defined as a trait that is characterised by a tendency to be passionate about and persevere towards the achievement of long-term goals. A newly developed questionnaire, L2-Grit Scale, which assesses…

Measuring the quality of classroom-based interactive shared book reading within the early childhood classroom represents a specific dimension of teacher-child interactions that is of great interest to researchers. This interest reflects decades of research demonstrating the benefit of reading to young children in both the home and the classroom.…

Introduction: One of the many notions that have been introduced in education in the last 50 years is that of learning styles. This idea is very popular and enjoys good acceptance. However, from a scientific perspective this notion is very controversial. In this sense, Coffield, Moseley, Hall, and Ecclestone, made the first systematic review on the…

This paper reviews the International English Language Testing System's speaking sub-test in the East Asia region with reference to theoretical and practice-based perspectives and identifies future research opportunities to enhance the measures of test qualities found. The test's construct validity was seen to accurately measure the abilities…

The Scylla and Charybdis in this discussion of teacher evaluation are standardized achievement test data on the one hand, and classroom observational systems on the other. These are the two most common methods used to judge teachers' competency. Both have serious flaws: the former primarily with validity, the latter primarily with reliability. At…

Purpose: This study examines the psychometric properties of the Teamwork Scale for Youth, an assessment designed to measure youths' perceptions of their teamwork competency. Methods: The Teamwork Scale for Youth was administered to a sample of 460 youths. Confirmatory factor analyses examined the factor structure and measurement invariance of the…

There is empirical evidence to suggest that oral language and vocabulary on entering kindergarten are the best predictors of later reading success. Identifying skills that are predictive of later achievement using psychometrically sound measurement methods is a necessary component of early intervention efforts. Currently, there are limited methods…

To efficiently assess multiple psychological constructs and to minimize the burden on respondents, psychologists increasingly use shortened versions of existing tests. However, compared to the longer test, a shorter test version may have a substantial impact on the reliability and the validity of the test scores in psychological research and…
