This study examined the construct validity of the Autism Classification System of Functioning: Social Communication (ACSF). Participants included 145 parents of children with autism (2-19 years). The degree of convergent and discriminant validity between parent reported ACSF and subscales from Social Responsiveness Scale 2nd edition and Behavior…

The aim of this study is to examine 8th grade students' Van Hiele geometry thinking levels, proof writing and justification skills. The research was carried out with sixteen eighth grade students of a private school in Sivas. Participants were selected based on an easily accessible sample. The data were collected from the students who participated…

Parental monitoring (PM) is a key construct in research on children's well-being and healthy development referring to the attention parents pay to their children's activities and whereabouts. However, existing literature suggests that the psychometric properties of its measurement tools are still perfect. For this study, a revised Italian parental…

The purpose of this study was to examine the psychometric properties of the Self-Efficacy Questionnaire (SEQ), a self-reported questionnaire using Rasch analysis, a one-parameter logistic probability model based on scientific measurement principles. Rasch analysis was completed using the rating scale model. The various analyses allow researchers…

An online intro-to-proof course provided an unexpected opportunity for a series of email exchanges that yielded insights into one student's mathematical thinking and the ambiguous role of mathematical jargon in miscuing this student's reasoning. The jargon deals with the notation [limit value of a function], which encapsulates multiple conceptual…

Researchers continue to extend the community of inquiry (COI) framework, highlighting its utility in online and blended learning environments for providing a successful learning experience. Recent studies have added the learning presence dimension to the classic COI framework which contains teaching, social, and cognitive presences, to represent…

Background: The objective of this systematic review is to identify characteristics, trends, and gaps in measurement in Science, Technology, Engineering, and Mathematics (STEM) education research. Methods: We searched across several peer-reviewed sources, including a book, similar systematic reviews, conference proceedings, one online repository,…

In this paper, we discuss the development and initial validation of an instrument, namely IV-SOPRA (Index of Violence Suffered and Practiced), measuring levels of violence suffered and practiced by students in Higher Education institutions; thus, seeking to advance research into the issue of violence connected to Higher Education. Participants are…

Geometric constructions present an opportunity to help students develop geometric proofs and justifications while actively creating mathematical representations (Mariotti, 2001). Though traditionally carried out with paper and pencil, dynamic geometry software allows students to produce more precise constructions with greater certainty…

Early college high schools (ECHS) in North Carolina are small public schools of choice on college campuses that seek to promote attaining postsecondary credits in high school, college readiness, and postsecondary enrollment for underrepresented groups. Evidence from randomized control trial (RCT) has shown positive effects of the ECHS model on…

Early college high schools (ECHSs) in North Carolina are small public schools of choice on college campuses that seek to promote attaining postsecondary credits in high school, college readiness, and postsecondary enrollment for underrepresented groups. Evidence from randomized control trials (RCTs) has shown positive effects of the ECHS model on…

The present study explored the development and initial validation of a measure of doctoral student self-efficacy for students in Health Profession Training (HPT) programs. There is a gap in existing scales that measure the full spectrum of tasks that contribute to doctoral self-efficacy. The scales that do exist focus on broad self-efficacy (Chen…

Purpose: The purpose of this study is to validate the psychometric properties of the Self-Perceived Employability Scale in the context of the United Arab Emirates (UAE-SPE) and to verify the model fit of the UAE-SPE and University Commitment Scale (UC) (Rothwell "et al.," 2008) for undergraduate students. Design/methodology/approach: A…

This study fills a gap with TPACK instrumentation by validating a survey instrument for use specifically with secondary mathematics in-service teachers in the United States using an instrument originally developed in Australia (Handal et al., 2012). A comparable national sample was surveyed in the U.S. to the original Australian instrumentation…

To ascertain whether lecturers had the pedagogical competency skill needed in impacting students with necessary skills they need outside school, this study developed a scale to measure Lecturers' Pedagogical Competence (LPCS) in universities using item response theory. The pedagogical competence of university lecturers was assessed using a set of…
