This article reports on the design of the Professional Development Needs Analysis Questionnaire for Deputy Principals (PDNAQ) to measure the problems they experienced and the skills they needed. In the literature, no validated questionnaire to measure the problems experienced and skills needed by deputy principals in South African schools was…

Several previous factor-analytic studies on the construct validity of grammaticality judgment tests (GJTs) concluded that untimed GJTs measure explicit knowledge (EK) and timed GJTs measure implicit knowledge (IK) (Bowles, 2011; R. Ellis, 2005; R. Ellis & Loewen, 2007). It has also been shown that, irrespective of the time condition chosen,…

This study aims to develop a measurement tool that will enable the determination of school administrators' and teachers' opinions on educational technologies. The items prepared by scanning the literature were presented to the opinions of the experts. Following the opinions, the 51-item trial form was applied to a total of 406 administrators and…

Context-based learning (CBL) approaches have been recommended and expanded in science education to make science more relevant to students by connecting science content with students' daily life. Subsequently, in order to implement CBL at school, a group of scenarios has been produced by several stakeholders. However, there is a lack of resources…

The current study aimed to adopt and assess the psychometric properties and measurement invariance of Grit-S among Omani and American students (N = 487) using Exploratory Factor Analysis (EFA) and Multi-Group Confirmatory Factor Analysis (CFA). The scale's construct validity was estimated by investigating its associations with achievement goal…

The central purpose of this paper is to examine validity problems arising from the multiple-choice items and technical passages in the Test of English as a Foreign Language Internet-based Test (TOEFL iBT) reading section, primarily concentrating on construct-irrelevant variance (Messick, 1989). My personal TOEFL iBT experience, along with my…

The purpose of this study was to validate a new inventory designed to measure epistemic beliefs concerning the justification of knowledge claims encountered on the Internet. Confirmatory factor analysis of the scores of 394 preservice teachers showed that a three-factor model including justification by authority, justification by multiple sources,…

This study developed and validated an instrument for assessing teachers' perceptions of culturally responsive teaching (CRT) in technology-supported learning environments. The construct validity of this instrument was examined via confirmatory factor analysis and the multiple dimensional partial credit model (MPCM) for item responses. Results…

Teachers play an important role supporting young people to form their career identities and to make successful transitions into further learning and work. In England, there has been limited research that has looked specifically at the role of teachers and none of which has tried to establish a measure of teacher attitude toward careers work. This…

This research aims to complete Turkish adaptation, validity and reliability studies for the Math and Me Survey developed by Adelson and McCoach for use in determining the students' attitudes towards mathematics in the transition from primary school to middle school. Within the scope of validity and reliability studies for the scale, data gathered…

This paper describes procedures by which two types of measures of Pedagogical Content Knowledge (PCK) were developed and validated: (a) PCK Survey and (b) PCK Rubric. Given the topic-specificity of PCK, the measures centered on photosynthesis as taught in high school classrooms. The measures were conceptually grounded in the pentagon model of PCK…

The current study describes the development and validation of a novel scale (BILEX) designed to assess young bilingual children's receptive vocabulary in both languages, their conceptual vocabulary, and translational equivalents. BILEX was developed to facilitate the assessment of vocabulary size for both of the children's languages within one…

This study aimed to develop Academic Motivation Scale for Learning Information Technology for university students. For this purpose, 120 randomly selected university students studying in different classes and faculties at KSU were invited to the study during the 2016-2017 academic year. To define the scale indicators students were asked to answer…

Following previous research which showed the significance of learners' self-efficacy and dispositions towards progression in school and university transition, we developed and validated similar measures for use in modelling undergraduate students' Learning Gain (LG). We validated three dimensions of confidence using data from a sample of (mainly…

Given the centrality of argumentation in the Next Generation Science Standards, there is an urgent need for an empirically validated learning progression of this core practice and the development of high-quality assessment items. Here, we introduce a hypothesized three-tiered learning progression for scientific argumentation. The learning…
