Qualitative thematic analysis is a commonly used and widely applicable form of qualitative analysis, though it can be challenging to implement. Due to its use across research questions, qualitative traditions, and fields, thematic analysis is also prevalent in mixed methods studies. Despite its widespread use, the term "thematic…

Research has shown that multiple-indicator multiple-cause (MIMIC) models can result in inflated Type I error rates in detecting differential item functioning (DIF) when the assumption of equal latent variance is violated. This study explains how the violation of the equal variance assumption adversely impacts the detection of nonuniform DIF and…

Problem solving and proofs have always played a major role in mathematics. They are, in fact, the heart and soul of the discipline. The using of a number of different proof techniques for one specific problem can display the beauty, and elegance of mathematics. In this paper, we present one specific, interesting geometry problem, and present four…

Introduction: There are numerous instruments for the measurement of gender awareness. However, there are relatively few validated instruments with a broad overarching holistic vision of gender that do not approach the issue from an adult perspective. For this reason, this study puts forward validated scale for measurement of Gender Awareness…

This study aimed to adapt and validate the Parents Education Anxiety Questionnaire (PEAQ) for the Indonesian context. The sample included 222 parents of school-aged children, predominantly mothers (84.7%) and fathers (15.3%). The results indicated that the adapted questionnaire exhibited good reliability, with a Cronbach's alpha coefficient of…

The purpose of this study was to assess the validity of School-Level Environment Questionnaire (SLEQ) in the Vietnam context. The study tested the nomological validity of the main measurement model and a competing model. The participants included 29 interviewees and 408 Vietnamese high-school teachers in Ho Chi Minh City. Interview data were used…

This work is devoted to exploring proof abilities in Graph Theory of undergraduate students of the Degree in Computer Engineering and Technology of the University of Seville. To do this, we have designed a questionnaire consisting of five open-ended items that serve as instrument to collect data concerning their proof skills when dealing with…

In clinical and forensic evaluations, clinical neuropsychologists measure performance validity using standalone and embedded measures. Given the need to capture neuropsychological functioning through a variety of cognitive tests, newer, more sensitive measures should be evaluated for their utility in comparison to already established measures.…

This methodological study aimed to assess the validity and reliability of the Turkish version of the Evaluation of the Impact of Hearing Loss in Adults (ERSA) questionnaire for individuals with treated hearing loss. The study involved 200 participants, and both exploratory factor analysis and confirmatory factor analysis were used to examine…

Most teacher education assessments are criticized for lacking validity and reliability. This study describes the process of developing the Observation of Field Performance rubric to assess initial teacher candidates' classroom performance and establishing the content validity as well as reliability of the rubric. A panel of content area experts…

The purpose of this study was to compare the classification accuracy of data produced by the previous year's end-of-year New York state assessment, a computer-adaptive diagnostic assessment ("i-Ready"), and the gating combination of both assessments to predict the rate of students passing the following year's end-of-year state assessment…

The Pearson Test of English Academic (PTE-A), a widely used high-stakes language proficiency test for university admissions and migration purposes, underwent a notable change from a three-hour to a two-hour version in November 2021. The implementation of the new version has prompted inquiries into the washback effects on various stakeholders.…

The urgent need for teachers and students for innovative learning media that integrates local context (ethnoscience), and technology (STEM) to improve students' science process skills is the main basis for the development of this electronic module. This study aims to produce an interactive STEM ethnoscience science electronic module. The…

Grit--"perseverance and passion for long-term goals" (Duckworth, Peterson, Matthews, & Kelly, 2007, p. 1087)--has attracted the attention of researchers in fields ranging from psychology to business to education (e.g., Robertson-Kraft & Duckworth, 2014; Robins, 2019). Continuing the line of research that explores the domain…

The development of attitudes toward science instruments has recently emerged in science education research. However, a comprehensive review of their psychometric properties, using currently accepted assessment standards, has not yet been completed. Consequently, this review discusses the validity and reliability of 18 measures published between…
