This note is concerned with the benefits that can result from the use of the maximal reliability and optimal linear combination concepts in educational and psychological research. Within the widely used framework of unidimensional multi-component measuring instruments, it is demonstrated that the linear combination of their components that…

In response to the prevalence of perceived internship Pick-up Artist(PUA) behaviours and the lack of appropriate measurement tools, the purpose of this study was to develop and validate a new self-designed questionnaire, the Perceived Internship PUA Scale (PIPUAS), to assess college student interns' perceptions of internship PUA behaviours. The…

With technology integration efforts expanding to early childhood education globally, assessing preschool teachers' technological competence beliefs is imperative. However, most existing tools measuring teachers' information and communication technology (ICT) competence beliefs focused on primary through secondary grades. This study examined the…

Online self-learning became widespread after the onset of the COVID-19 pandemic, and during this period, learners' self-leadership became an important measure of their competency. This study aims to verify the validity and reliability of the tool by translating the Abbreviated Self-Leadership Questionnaire (ASLQ) into Korean. Through web-based…

This paper aims to describe the development process of the Observation Protocol for Teaching Activities in Mathematics (POAEM) and to report the findings from the qualitative and statistical analyses used to provide evidence of validity and reliability of the information collected with the first version of the POAEM. As part of this development…

Scholarly debate about student evaluations of teaching (SETs) often focuses on whether SETs are valid, reliable and unbiased. In this article, we assume the most optimistic conditions for SETs that are supported by the empirical literature. Specifically, we assume that SETs are moderately correlated with teaching quality (student learning and…

Non-formal adult education (NFE) provides adults of all ages with the opportunity to acquire skills, knowledge, and expertise. However, there is currently a lack of validated instruments that measure the factors of NFE non-participation in European countries, particularly their barriers. One exception is the Non-participation in Non-formal…

The Expectancy-Value model has been extensively used to understand students' achievement motivation. However, recent studies propose the inclusion of cost as a separate construct from values, leading to the development of the Expectancy-Value-Cost model. This study aimed to adapt Kosovich et al.'s ("The Journal of Early Adolescence", 35,…

The objectives were to examine the factorial structure of the Academic Procrastination Scale-Short Form (APS-S) and the measurement invariance across gender and educational levels, to determine possible differences in procrastination across gender, educational levels, and grades. The sample was formed of 1486 Spanish primary and secondary school…

The measurement error in principal components extracted from a set of fallible measures is discussed and evaluated. It is shown that as long as one or more measures in a given set of observed variables contains error of measurement, so also does any principal component obtained from the set. The error variance in any principal component is shown…

Existing measures of test anxiety used with the college student population are old with old norms and old items, and they do not capture the multiple dimensions of the test anxiety construct or assess facilitating anxiety. In the present study, the validity of the scores of a new, multidimensional measure of test anxiety with a facilitating…

Adoption of new instructional standards in science demands high-quality information about classroom practice. Teacher portfolios can be used to assess instructional practice and support teacher self-reflection anchored in authentic evidence from classrooms. This study investigated a new type of electronic portfolio tool that allows efficient…

Moral psychology has been moving toward consideration of multiple kinds of moral concepts and values, such as the Ethics of Autonomy, Community, and Divinity. While these three ethics have commonly been measured qualitatively, the current study sought to validate the long and short forms of the Ethical Values Assessment (EVA), which is a…

Being an expert involves explaining how things are supposed to work, and, perhaps more important, why things might not work as supposed. In this study, researchers surveyed scholars with expertise in value-added models (VAMs) to solicit their opinions about the uses and potential of VAMs for teacher-level accountability purposes (for example, in…

As educational practitioners and policymakers expand the range of student outcomes they assess, student perception surveys--particularly those targeting social-emotional learning--have grown in popularity. Despite excitement around the potential for measuring a wider array of important student outcomes, concerns about the validity of the…
