Curriculum adaptation portrays the way teachers 'tweak' the curriculum. The findings of related studies are based solely on qualitative data, and there is no instrument that can determine curriculum adaptation patterns. Based on this gap, the aim of this study is to develop the Curriculum Adaptation Patterns Scale (CAPS). After examining the…

Technological advancements, particularly in artificial intelligence, significantly transform our society and work practices. Computational thinking (CT) has emerged as a crucial 21st-century skill, enabling individuals to solve problems more effectively through an automation-oriented perspective and fundamental concepts of computer science. To…

This investigation utilized publicly available data from the High School Longitudinal Study 2009 (HSLS:09) by the National Center for Educational Statistics (NCES) to examine any latent structures among variables which may empirically support the validity and reliability of a mathematical sense of belonging (MSB) construct. Using the nationally…

Concept mapping is a practical approach to meaningful learning, and emotion is one of the most important factors that affect students' learning. However, few studies have focused on learners' emotions of concept mapping. This research aims to develop and verify a CM-ES and to investigate university students' emotions of concept mapping with the…

The aim of this study is to develop a scale that measures the attitudes of physical education and sports teachers towards measurement and evaluation. In this study, scale development principles and steps of DeVellis (2017) were used. Initially, a literature review was conducted, 19 physical education and sports teachers were interviewed in written…

In this study, it is aimed to develop a scale to be used to determine the STEM career interest of high school students. Because, when STEM career studies in the literature are examined, the lack of STEM career scale for high school students is remarkable. In this research, developing STEM Career Interest Scale for high school students is important…

The purpose of this research is to prepare a valid and reliable measurement tool in order to determine the acquisition of teacher candidates under the hidden curriculum in teacher training process. The research is a field study of descriptive quality. In the development of the scale, firstly the related literature has been examined and a pool of…

The aim of this study is to adapt the scale of the factors affecting argumentation instruction into Turkish. A total of 143 preservice science teachers studying in two different universities located in the east and west of Turkey participated in this study.

Short forms of psychometric scales have been commonly used in educational and psychological research to reduce the burden of test administration. However, it is challenging to select items for a short form that preserve the validity and reliability of the scores of the original scale. This paper presents and evaluates multiple automated methods…

This study reports on the development, validation, and reliability of a geometry disposition scale (GDS) to measure pre-service teachers' (PSTs') attitudes to geometry learning. PSTs from two Colleges of Education (CoEs) in Ghana volunteered to participate in the study (N = 153). A principal component analysis (PCA) extracted four factors: deep…

The Council for the Accreditation of Educator Preparation Programs (CAEP), required evidence of reliability and validity of measures used in a university's Educator Preparation Program (EPP). This paper describes processes that provided this evidence for the Teacher Performance Assessment (TPA). Literature examined included Messick (1989), Linn…

The aim of this article is to report the validity and reliability of Teacher Leadership Inventory (TLI). The sample of the study consists of 244 trained teachers who are chosen using random sampling technique from 19 secondary schools in Perak. The content validity, criterion validity and construct validity analyses have been carried out by using…

The Additive Factor Model (AFM) is a cognitive diagnostic model that can be used to predict student performance on items in a context that allows for student learning. Within AFM, "skills" have a learning rate, and student acquisition of a skill depends only on the number of opportunities a student has had to exercise that skill and the…

Existing studies have defined and assessed disciplinary literacy, mathematical literacy, and general academic language. However, there is a need to define and assess mathematics discipline-specific language (MDL), particularly for elementary school teachers. Therefore, the purpose of this study was to develop a research instrument to assess the…
