Validity is broadly defined as how well something measures what it's supposed to measure. The reliability and validity of scores from assessments are two concepts that are closely knit together and feed into each other.

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…

The 2-minute step test (2MST) requires minimal resources and is valid in adults older than 60 years. Here we investigate if the 2MST can be used to estimate peak oxygen consumption (VO[subscript 2]peak) in healthy middle-aged adults (40-59 years old). Thirty-six participants completed the 2MST and a maximal graded treadmill test with…

The continuous testing framework, where both successful and unsuccessful examinees have to demonstrate continued proficiency at frequent prespecified intervals, is a framework that is used in noncognitive assessment and is gaining in popularity in cognitive assessment. Despite the rigorous advantages of this framework, this paper demonstrates that…

In order to ensure content validity by covering a broad range of content domains, the testing times of some educational large-scale assessments last up to a total of two hours or more. Performance decline over the course of taking the test has been extensively documented in the literature. It can occur due to increases in the numbers of: (a)…

Research Findings: Childcare provider stress and job satisfaction has been found to influence childcare quality in high-income contexts, but this phenomenon has yet to be studied in a low- or middle-income country. In 2019-2020, we tested the reliability and validity of the Child Care Center Work Environment Scale (CCCWES) with 416 childcare…

The objective of this research is to construct a scale for assessing the extent of parents' 'sharenting' behavior and to assess its psychometric characteristics. The development of the Sharenting Scale commenced with a comprehensive review of relevant literature. Subsequently, a preliminary version of the scale was administered to 300 parents who…

Black teachers experience racialized microaggressions at varying levels in their professional settings. Existing measures of these microaggressions are not context specific. We developed items following a critical quantitative research inquiry approach. Item response theory (IRT) provided validation evidence for the Teacher Experiences of…

Most internationally recognized instruments for the screening and diagnosis of autism spectrum disorder have been developed in the USA, which calls into question the degree of their cultural adaptation to diverse populations. The aim of this study is to examine the characteristics of social communication in typically developing Croatian-speaking…

Online learning has grown due to the advancement of technology and flexibility. Online examinations measure students' knowledge and skills. Traditional question papers include inconsistent difficulty levels, arbitrary question allocations, and poor grading. The suggested model calibrates question paper difficulty based on student performance to…

The rapid evolution of AI technologies has reshaped our daily lives. As AI systems become increasingly prevalent, AI literacy, the ability to comprehend and engage with these technologies, becomes paramount in modern society. However, existing research has yet to establish a comprehensive framework for AI literacy. This study aims to fill this gap…

Student identity measures in Science, Technology, Engineering, and Mathematics (STEM) fields are a strong predictor of future persistence in those disciplines. However, there is a paucity of studies with validated measures of students' computer science (CS) identity. The aim of the present study was to assess the reliability and validity of a…

There is a strong and growing focus on self-determination in French-speaking countries, and this pilot study reports the technical adequacy of the Self-Determination Inventory: Student Report (SDI:SR) French Translation. Data were collected with 471 French-speaking youth with and without disabilities in Canada (Quebec), Switzerland, France, and…

The aim was to determine the validity and test-retest reliability of the Sit to Stand App variables (rising time, vertical velocity, and power) for measuring single-leg sit-to-stand (STS) test compared to those derived from ground reaction force data. Twenty-seven female athletes performed the single-leg STS test over three consecutive sessions…

Anxiety, depression, and suicidality are major concerns among college students, though less is known about these constructs in autistic college students. Given the rising number of autistic individuals entering post-secondary education, adequate measurement and diagnosis of anxiety, depression, and suicidality is necessary to provide clinical care…
