Considerations related to generalization of a study's findings are often interconnected to researchers' judgements regarding the 'quality' of the methodology and methodological pluralism. Too often, researchers consider generalization as only possible with respect to quantitative studies with large numbers of randomly selected participants…

Eye gaze tracking has recently become indispensable for domains like virtual reality, augmented reality, human-computer interaction and advertisement. The commercial eye gaze tracking equipment is too expensive to be used by the masses. In this manuscript, a non-invasive, low-resolution ordinary camera-based system has been proposed for tracking…

The current study reviewed the practice and application of social validity assessments in single-case design (SCD) studies within the field of school psychology. Social validity refers to the acceptability of intervention or program goals, procedures, and outcomes to educators, families, and students. Understanding the ways social validity is…

This paper introduces the concept of logical consistency in students' thinking in mathematical contexts. We present the Logical in-Consistency (LinC) instrument as a valuable assessment tool designed to examine the prevalence and types of logical inconsistencies among undergraduate students' evaluation of mathematical statements and accompanying…

This article presents an inquiry-oriented lesson for teaching Lagrange's theorem in abstract algebra. This lesson was developed and refined as part of a larger grant project focused on how to "Orchestrate Discussions Around Proof" (ODAP, the name of the project). The lesson components were developed and refined with attention to how well…

In the early years, it has become essential to support the acquisition of computational thinking, which is seen as a 21st-century skill and new literacy. A valid and reliable measurement tool is needed to develop and evaluate educational practices related to these skills. "TechCheck" is a validated unplugged assessment of computational…

In recent years, lifelong learning has gained prominence, necessitating a continuous commitment from learners to enhance their skills and knowledge. During the lifelong learning process, it is essential to precisely assess the cognitive states of lifelong learners, as this will provide a learning report and further support subsequent learning…

This study aimed to develop and validate the Evaluator Competencies Assessment Tool (ECAT) Cultural Competencies Subscale, which measures cultural competence among evaluators. By addressing the scarcity of validated tools in this area, the study offers professionals a valuable resource to assess their strengths and areas for improvement. The…

Combining methods from earlier content validity and more contemporary content alignment studies may allow a more complete evaluation of the meaning of test scores than if either set of methods is used on its own. This article distinguishes item relevance indices in the content validity literature from test representativeness indices in the…

Although school psychologists often comment on examinee motivation in their reports, systematic evaluation of effort is not common practice. Empirical assessment of performance effort provides critical evidence for the validity of evaluations and will likely lead to more valid assessments, recommendations, and placements. This article focuses on…

Research capability is one of the essential capabilities of scholars for effectively conducting their work. Yet current research lacks a structured exploration and measurement scale for Chinese scholars on this matter. In the Chinese research context, this study conducted two questionnaires based on the Research Self-Efficacy Scale (RSES) among…

The Perceptions of Inclusion Questionnaire (PIQ) assesses the perceptions of inclusion in 3rd to 9th grade students through three scales: social inclusion, emotional inclusion, and academic self-concept. This study aimed to establish the psychometric properties of the Spanish version of the instrument (PIQ-Spa) since no prior formal validation of…

Considering the crucial role of education in offering mitigation and adaptation strategies for climate change, there is a clear need for objective tools to assess its impact on the understanding of the issue among secondary school students. This paper describes the methodological design used to build and validate an instrument that explores…

In this study, an attempt was made to develop a valid and reliable measurement tool to determine teachers' self-efficacy levels for teaching metacognitive listening strategies. The study group consisted of 205 teachers for EFA and 248 teachers for CFA. As a result of the analyzes, a scale consisting of 16 items with 4 factors was developed. It was…

In this paper, a simple proof of the Morley's Trisector Theorem is presented which involves basic plane geometry only. The use of backward geometric approach, trigonometry or advanced mathematical techniques is not required. It is suitable for introducing to secondary or undergraduate students, as well as teachers or instructors for learning or…
