Objective: This study aimed to validate the Cultural Humility and Enactment Scale (CHES) through (a) examining its factor structure with multiple samples; (b) employing item response theory (IRT) analysis to examine its item-level characteristics; (c) reducing potential redundancies among items; and (d) conducting measurement invariance (MI)…

Objective: This study examines the validity of the ASRS-5 as a new screening tool for ADHD and evaluates its proposed screening cut-off in a general population context. Method: A nationally representative sample of 2,002 individuals aged 18 to 80 years was surveyed using the ASRS-5, with complete data obtained from 714 participants. Psychometric…

This study aimed to expand the psychometric properties of the Theory Evaluation Scale (TES), specifically its structure, construct validity, and internal consistency. A demographically diverse sample of 113 social work faculty (N = 113) utilized the TES to appraise a social work theory and their responses were used for exploratory factor analysis…

Background: For decades, education researchers have relied on the work of Campbell, Cook, and Shadish to help guide their thinking about valid impact estimates in the social sciences (Campbell & Stanley, 1963; Shadish et al., 2002). The foundation of this work is the "validity typology" and its associated "threats to…

Diagnostic tests have been developed previously to measure algebraic thinking skills; however, the tests do not specifically address algebraic problem-solving. Thus, an Algebraic Thinking Test (ATT) Instrument was developed to measure algebraic thinking skills in problem-solving involving linear equations. ATT comprises nine open-ended questions…

This study focused on the development and validation of the Sense of Online Community Scale (SOCS), which includes 28 Likert-type scale items across six subscales: (1) program community; (2) program academic activities; (3) program social activities; (4) institutional academic activities; (5) institutional social activities; and (6) affiliation.…

This study compares the psychometric properties of two popular teacher self-efficacy scales, namely, Teachers' Sense of Efficacy Scale (TSES) and Teacher Efficacy Scale (TES). This study was quantitative in nature and distributed the two scales to 287 preservice teachers in the USA and in Australia. Findings indicate that the two scales function…

The Cognitive Test Anxiety Scale (CTAS) is a unidimensional scale designed to measure the cognitive aspect of test anxiety. The instrument has been adapted in several countries, and convincing psychometric properties have been found; however, uncertainties remain regarding its factor structure. Therefore, the aim of this study is twofold: to…

As implementation of green chemistry into university-level courses increases, it is vital that educators have a tool to rapidly measure student knowledge of green chemistry principles. We report the development of the Assessment of Student Knowledge of Green Chemistry Principles (ASK-GCP) and evaluation of its sensitivity and effectiveness for…

Organization, time management, and planning (OTMP) skills are behavioral manifestations of executive functioning linked to academic outcomes. Interventions to improve OTMP skills have shown favorable outcomes. The Children's Organizational Skills Scale parent and teacher forms (COSS-P, COSS-T) are widely used for assessing OTMP skills, but there…

Proponents of learning styles-based instruction recommend using learning styles inventories in school settings. One such inventory is Kolb's Learning Style Inventory (LSI). Critics, on the other hand, discourage the use of such questionnaires because of some challenges associated with learning styles-based instruction. Despite these challenges,…

Despite the importance of evolution to understand biology, there is significant evidence that many biology teachers have difficulties to successfully teach this topic. The purpose of this study is to describe procedures by which a paper-and-pencil instrument to assess teachers' pedagogical content knowledge for evolution (PCK[subscript evo]) was…

Background: To examine levels of reading self-efficacy in college students and further understand sources that foster reading self-efficacy at the postsecondary level, there is a need for a valid scale that can be used for college student populations. Methods: In Phase 1, 160 items were generated and reviewed by a panel of experts and a group of…

Introduction: Research suggests that one of the most pervasive consequences of traumatic events is the resulting dysregulation of emotions. Educators, including teachers, administrators, and student services staff, are instrumental in supporting students as they navigate overwhelming emotions by modeling and teaching skills to regulate emotional…
