This study aims to conduct the Turkish adaptation, validity, and reliability study of the Theory of Mind Inventory-2 (TOMI-2) developed by Hutchins and Prelock (2016) for 3-5-year-old children. The study group consists of 310 mothers with children in the 3-5 age group in Konya city center. Personal Information Form and Theory of Mind Inventory-2…

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…

I created the 15-item Learner-Centered Syllabus Scale (LCSS) based on the work of Cullen and Harris. The purpose of this study was to assess the factor structure, reliability, and validity of the LCSS. Four blind coders assessed 175 syllabi using the LCSS with 92% inter-rater agreement. To establish concurrent validity, each blind coder rated the…

This study aims to validate a Korean version of the Brief Version of the Child Abuse Potential Inventory (BCAP-K) for use with childcare providers in South Korea. By employing a stratified sampling method, 808 childcare providers in charge of infants' classes were selected for participation. Participants completed a questionnaire that included…

Motivation impacts student academic performance. A performance task to directly assess writing motivation in young children is needed. The purpose of this investigation was to evaluate the validity of the Writing Challenge Task (WCT), a task-oriented assessment created to measure writing motivation with 106 kindergarten students in the rural…

In an attempt to engage more students in Science, Technology, Engineering and Mathematics (STEM) subjects, schools are encouraged by STEM educators and professionals to introduce students to STEM through projects which integrate skills from each of the STEM disciplines. Because little is known about the learning environment of STEM classrooms, we…

Successful early mathematical development is vital to children's later education, employment, and wellbeing outcomes. However, established measurement tools are infrequently used to (i) assess children's mathematical skills and (ii) identify children with or at-risk of mathematical learning difficulties. In response, this pre-registered systematic…

We compared the influence of open-book extended duration versus closed book time-limited format on reliability and validity of written assessments of pharmacology learning outcomes within our medical and dental courses. Our dental cohort undertake a mid-year test (30xfree-response short answer to a question, SAQ) and end-of-year paper (4xSAQ,…

Drawing from the developmental and cognitive mathematics literature, the purpose of this study was to investigate the reliability, validity, and diagnostic utility of a widely-researched number line task in kindergarten. Specifically, the Number Line Assessment 0-100 (NLA 0-100) as compared to an established kindergarten screening measure was…

This paper reports an investigation into the psychometric properties of the COR-Advantage1.5 (COR-Adv1.5) assessment tool, a criterion-referenced observation-based instrument designed to assess the developmental abilities of children from birth through kindergarten. Using data from 8534 children participating in a state-funded preschool program…

This study was an initial psychometric investigation of the Universal Behavior Screener (UBS), a nine-item screening measure developed by psychologists within the Hawai'i Department of Education (HIDOE) to identify elementary school youth at risk for social, emotional, and behavioral concerns. Data from nine teachers reporting on 230 students at…

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…

The purpose of this study was to evaluate the psychometric properties of an Arabic version of the Career Adapt-Abilities Scale (CAAS) using a Jordanian sample. The sample included 233 Jordanian citizens with Arabic as their native language. The final model revealed a moderate fit (root mean square error of approximation = 0.072) and was within the…

Motivation for reading is important to comprehension and has been studied extensively in offline reading contexts. However, little is known about the role of motivation in online reading, a new and increasingly important context for reading, largely because of a lack of valid and reliable instruments to estimate a student's motivation for online…

Background: Child anxiety sensitivity (AS) is measured almost exclusively using the Childhood Anxiety Sensitivity Index (CASI). Yet, in the context of significant discrepancies regarding the CASI factors and how they are scored and reported, it remains unclear whether the CASI reliably and validly assesses the purported multifactorial AS…
