This article builds upon a proiminent definition of construct validity that focuses on variation in attributes causing variation in measurement outcomes. This article synthesizes the defintion and uses Rasch measurement modeling to explicate a modified conceptualization of construct validity for assessments of developmental attributes. If…

The procedures of carrying out factorial invariance to validate a construct were well developed to ensure the reliability of the construct that can be used across groups for comparison and analysis, yet mainly restricted to the frequentist approach. This motivates an update to incorporate the growing Bayesian approach for carrying out the Bayesian…

Assessment literacy is an essential competency area for professional counselors who administer tests and interpret the results of participants' scores. Using factor analysis to demonstrate internal structure validity of test scores is a key element of assessment literacy. The underuse of psychometrically sound instrumentation in professional…

Across the world, teacher quality has come to be recognised as one of the most important variables affecting student outcomes; consequently, the regulation of entry into the profession is the subject of iterative review. The traditional 'one-off' interview, involving an interviewee and two or more interviewers, is a common, but not unproblematic,…

Professor Gordon argues for a significant reorientation in the focus and impact of assessment in education. For the types of assessment activities that he advocates to prosper and positively impact education, serious attention must be paid to two important topics: (1) the conceptual underpinnings of the assessment practices we develop and use to…

Despite the importance of evolution to understand biology, there is significant evidence that many biology teachers have difficulties to successfully teach this topic. The purpose of this study is to describe procedures by which a paper-and-pencil instrument to assess teachers' pedagogical content knowledge for evolution (PCK[subscript evo]) was…

An increased focus on transparency and replication in science has stimulated reform in research practices and dissemination. As a result, the research culture is changing: the use of preregistration is on the rise, access to data and materials is increasing, and large-scale replication studies are more common. In this article, I discuss two…

Applying qualitative comparative analysis (QCA) to large Ns relaxes researchers' case-based knowledge. This is problematic because causality in QCA is inferred from a dialogue between empirical, theoretical, and case-based knowledge. The lack of case-based knowledge may be remedied by various robustness tests. However, being a case-based method,…

Researchers, theorists, and practitioners have expressed a renewed interest in the longitudinal dynamics of personality characteristics in adulthood, including organic life span trajectories and their amenability to volitional change. However, this research has apparently not yet expanded to include the Dark Triad (psychopathy, narcissism,…

This article describes the development and initial testing of the "Elementary Literacy Coach Self-Efficacy Survey", a new instrument designed and created to assess literacy coaches' efficacy for coaching-specific tasks. A synthesis of literature on literacy coaching tasks and experts in the coaching field were used to craft the…

In using the Rasch model to improve the quality of an instrument, analysis purports to determine if the sample collaborates well with the items in the instrument such that the results are measuring a single underlying variable. The relevant properties of Rasch analysis are reliability and validity which are key indicators of the quality of a…

Developed as an integral component of many higher education programs, internships provide a multitude of benefits for participating students. However, there is a lack of tools designed to measure internship-related learning outcomes. Therefore, this article will present the process of constructing and validating a scale that can be used to…

The redesigned "TOEIC Bridge"® tests were designed to evaluate test takers' English listening, reading, speaking, and writing skills in the context of everyday adult life. In this paper, we summarize the initial validity argument that supports the use of test scores for the purpose of selection, placement, and evaluation of a test…

In Australia, one of the key findings of the Teacher Education Ministerial Advisory Group was that not all graduating pre-service teachers possess adequate pedagogical content knowledge (PCK) to teach effectively. The concern is that higher education providers working with pre-service teachers are using pedagogical practices and assessments which…

The article serves as a guide for researchers in developing evidence of validity using bivariate correlations, specifically construct validity. The authors outline the steps for calculating and interpreting bivariate correlations. Additionally, they provide an illustrative example and discuss the implications.
