This study examined the content validity and preliminary structural validity of the Sensory Integration Infant Routines Questionnaire (SIIRQ), a tool designed to screen for behaviors reflecting possible sensory integration concerns in children aged between 8 and 24 months. This study included two main phases. In phase 1, we examined content…

The aim of this study is to characterize ways of reasoning and arguing that first year university mathematics students exhibit in problem-solving activities from a course that emphasizes the importance of formulating conjectures and the search for different ways to support or validate them. The use of a Dynamic Geometry System in the…

Understanding how students reason with logical implication is essential for supporting students' construction of increasingly powerful ways of reasoning in proofs-based mathematics courses. We report on the results of an NSF-funded case study with a mathematics major enrolled in an introductory proofs course. We investigate the epistemological…

As survey research in second language acquisition grows in popularity, the adherence to best practices associated with questionnaire quality is critical for a better understanding of factors that influence second language (L2) development. To ensure that a self-report scale targets the construct of interest and does it consistently and accurately,…

High quality of teacher-student relationships is widely recognized as fundamental part of good education. Moreover, students' self-efficacy beliefs, or their confidence to succeed within different domains at school, are important impact factors to achievement. Although there is support for an association between student-perceived teacher-student…

This study aims to adapt the revised Metacognitive Awareness of Reading Strategies Inventory (MARSI- R) into Turkish. MARSI-R is a self-report instrument designed to assess students' metacognitive awareness of reading strategies and perceived strategy use when reading school-related materials. 525 students (65% female, 35% male, Mage = 13 years…

Approximate mathematical treatments are commonly taught in undergraduate chemistry, but the validity ranges of these approximations have rarely been properly defined. We present error contour plots of commonly used quadratic approximations for calculating equilibrium proton concentrations of monoprotic acids. Students and instructors can easily…

Improving teacher selection is an important strategy for strengthening the quality of the teacher workforce. As districts adopt commercial teacher screening tools, evidence is needed to understand these tools' predictive validity. We examine the relationship between Frontline Education's TeacherFit instrument and newly hired teachers' outcomes. We…

Scale validation is vital to psychological research because it ensures that scores from measurement scales represent the intended construct. Factor analysis fit indices are commonly used to provide quantitative evidence that a proposed factor structure is plausible. However, there is mismatch between guidelines for evaluating fit of factor models…

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…

We elaborate on a new approach of assessing content-based epistemic clarity of college physics students in terms of their ability to discriminate between different epistemic warrants for propositions in a chained argument in physics. A threefold classification (nominal, physical, and mathematical) of warrants is used, with each class split into a…

Recent national research on the validity of the SAT shows that students with higher SAT scores are more likely to earn higher grades in college, and that SAT scores add about 15% more predictive power above high school grade point average (HSGPA) to estimate students' college performance (Westrick, Marini, Young, Ng, Shmueli, & Shaw, 2019).…

Validity of a measurement refers to appropriate test score meanings, uses, and interpretations (Messick, 1989; Kane, 1992). There are different approaches to validity: an evidentiary aspect of validity is one requiring gathering statistical evidence to evaluate test score meaning. A common approach to validation is comparisons of test score equity…

Purpose: This study aims to gain insights into how students perceive online examination practices and evaluation, as well as identify the key factors that impact their intentions toward online exams. Design/methodology/approach: This empirical study conducted in India utilized an online survey method between May 24 and June 14, 2022. The data were…

The COVID-19 epidemic has precipitated a rapid and widespread adoption of online education, leading to its normalization in contemporary society. Online education is evident across several educational levels. However, assessing the efficacy and effectiveness of these training programs can only be achieved by implementing a suitable evaluation…
