The aim of this study was to develop and validate a psychometrically-sound instrument to assess students' perceptions about class cohesion. Two studies were conducted. In Study 1, four steps were established: (1) development of the Class Cohesion Questionnaire (CCQ); (2) item selection; (3) item compression; and (4) exploration of psychometric…

The content validity ratio (CVR), which is suggested by Lawshe (1975), is a widely used index to quantify content validity. In this study, the Bayesian approach is used to determine the minimum number of experts required to agree an item is essential, and then the CVR is calculated.

The purpose of this study was to develop and validate a scale designed to measure physical educators' self-efficacy and sources of information to teach students with disabilities across different types of instructional placements for physical education. Scale construction consisted of four phases: (a) item development, (b) content validity, (c)…

The purpose of this study was to develop a questionnaire to assess body posture habits in adolescents' daily activities. To develop and assess the instrument we used the Delphi method, and a test-retest reliability design. The questionnaire consisted of 31 questions with 4-level Likert scale. One hundred and sixty-eight students were studied, 72…

Digital competence is a basic skill for citizens and should be systematically assessed, taking into account characteristics such as knowledge, skills and attitudes. However, measuring and identifying the digital competence of students is still a major challenge. To this end, the indicator model (INCODIES) has been developed and validated following…

Introduction: Self-regulation is the ability to adequately plan and manage one's own behavior in a flexible manner. It is a predictor of well-being, health, academic performance, among others. The psychometric characterization of the Self-Regulation Questionnaire-Abbreviated (CAR-abr.) composed of 17 items is presented. A versatile instrument,…

While previous studies on assessments focused on measurement of principles and constructs, existing attention is given to content validation involving vocational education and skills. The emphasis on content validation has prompted a holistic perspective of teaching and learning to demand alternative research approaches. Using evidence of content…

There is a growing recognition of the need for interventions to improve the healthcare of autistic adults. However, there is a dearth of validated measures to evaluate such interventions. Our objectives were to use a community-based participatory research approach to create an accessible set of patient- and proxy-reported instruments to measure…

The Content Proximity Project was designed to improve the content validity of the MAP® Growth™ assessments while retaining the ability for the test to adapt off-grade and meet students wherever they are in their learning. Two main features of the project were the development of an enhanced item selection algorithm, and a spring pilot study…

This article aims to explore the symptoms and characteristics of dyscalculia. This is a qualitative study. Five experts in the field of special education took part in a focus group interview. Each expert had more than ten years of experience in their area of expertise. To determine the content validity of the protocol, three experts in special…

The majority of students from elementary to tertiary levels have misunderstandings and challenges acquiring various statistical concepts and skills. However, the existing statistics assessment frameworks challenge practice in a classroom setting. The purpose of this research is to develop and validate a statistical thinking assessment tool…

The research aims to redesign and develop the Imagineering MOOC Instructional Design model (I-MOOC ID model) to enhance creative thinking and creative health media innovation. The exploratory sequential design mixed-method research method was used, and it was divided into three phases: (1) investigation and synthesis of the composition of the…

The progress of the nation is based on the competencies of the citizens, and the overall development of the person depends on the effectiveness of the educational system implemented in the country. The teacher is a key factor in the implementation of educational programs. Without a favorable attitude toward the teaching profession, teachers cannot…

Definitions of effective teaching focus on three primary areas: performances, essential knowledge, and critical dispositions. While no one measure provides a complete picture of teacher effectiveness, empirical inquiry into critical dispositions lags behind what is known about essential knowledge and performances. We found this underdevelopment…

The COVID-19 pandemic has transformed teaching and learning in ESL education, particularly through the integration of artificial intelligence (AI) technologies into current English Language Teaching (ELT) practices. However, to ensure the seamless integration of these technologies into ELT practices, a proper framework needs to be developed and…
