This research aims to develop an instrument for the evaluation of impulsivity traits in children and to examine the psychometric features of the developed scale. The process of developing the scale involved three main phases: namely, item generation, evaluation of content validity, and analysis of psychometric properties. The study sample…

The study took a Rasch measurement theory approach to validating the 10-item Digital Literacy Scale (DLS) using the unidimensional rating scale model (RSM). To that end, the study used the data from a sample of online Turkish university students. The study began the Rasch analysis with all 10 items in the scale and, to improve in the local…

Many researchers have separately developed instruments to measure environmental characteristics such as attitudes, values, and knowledge. However, there is no instrument used to measure all these aspects in one comprehensive instrument. This study is meant to develop and validate a green character instrument which reveals student behavior and…

Objective: This study aimed to develop and test a scale for measuring the quality of blended learning models in higher education. Methods: This research adopts a sequential mixed-method approach to construct a new measurement scale. The first phase consisted of the inductive approach to identify the items, followed by exploratory factor analysis.…

This study uses a rigorous research process to explore the psychometric properties of the Gifted Rating Scale-School Form (GRS-S) within the Qatari educational context. We employed stratified cluster sampling of 326 students (aged 6-13 years, M = 10.9) from 25 public schools in Doha. Data was collected in the second semester of the 2023-2024…

The aim of this research is to develop a reliable and valid scale to determine the mathematical thinking skills of gifted students. In addition, with the developed scale, thinking skills of gifted students was examined in terms of various variables. In this context, the research was carried out on two different study groups. The first stage of…

While numerical bipolar rating scales may evoke positivity bias, little is known about the corresponding bias in verbal bipolar rating scales. The choice of verbalization of the middle category may lead to response bias, particularly if it is not in line with the scale polarity. Unipolar and bipolar seven-category rating scales in which the…

The purpose of this study was to develop a reliable and valid rating scale for the use of the assessment and evaluation of lesson plans and teaching practices that are based on argumentation-based inquiry (ABI). The study covered two academic years (four academic semesters). Qualitative and quantitative methods were utilized throughout the…

This article focuses on the psychometric properties and characteristics of the Assessing School Settings: Interactions of Students and Teachers (ASSIST), an observational assessment administered by trained external observers of teacher practices, classroom context, and student behaviors at the classroom level. Study 1 examines variability,…

Augmented Reality (AR) is increasingly being adopted in education to foster engagement and interest in a variety of subjects and content areas. However, there is a scarcity of instruments to measure the instructional impact of this innovation. This article addresses this gap in two unique ways. First, it presents validation results of the…

Teacher rating scales (TRS) often play a part in service eligibility decisions for gifted services. Although schools regularly use TRS to identify gifted students either as part of an informal nomination process or through behavioral rating scales, there is little research documenting the between-teacher variance in teacher ratings and the…

Objective: To develop a short version of the Spanish 18-item ADHD-Rating Scale IV.es (sADHD-RS-IV.es) to be used as a potential screening tool in pediatric population. Methods: We recruited 652 subjects, ages 6 to 18 (mean ± SD = 11.14 ± 3.27): 518 patients with ADHD (per DSM-IV criteria); and 134 healthy controls. We performed a stepwise logistic…

This study aims to develop a valid and reliable measurement instrument to identify university students' attitudes towards flipped learning model. The research sample was composed of 487 pre-service teachers who attended a university. Relevant literature was reviewed a pool of items was formed and content and construct validity analyses as well as…

Background and Context: As computer science (CS) education expands and the need for well-prepared CS teachers grows, understanding what motivates teachers to teach CS can help address challenges to recruiting, preparing, and retaining teachers. Objective: The goal of this work was to develop and validate a scale that measures teachers' motivation…
