The way in which validity has been conceptualized has changed throughout the years. The focus in validation studies shifted from evaluating distinct components of validity to developing a comprehensive argument for the use and interpretations of test scores. The argument-based approach to validity incorporates the distinct types of the…

Two novel proofs show that the sum of a specific pair of normal random variables is not normal are established in this note. This is one of the most often misunderstood facts by first-year students in probability theory and statistics. The first proof is concise using the moment generating function. The second proof checks whether the moments of…

This chapter discusses the history of source evaluation methods within the ever-changing field of information literacy, including a critical assessment of one popular approach, the CRAAP Test. The author then endorses an alternative approach, lateral reading, which encourages students to engage more deeply when evaluating digital resources in an…

This article is part of a special LDRP research-to-practice series introducing key concepts to enable special education practitioners and other nonresearchers to be more informed research consumers. In the article, we explore how social validity is assessed in special education research and how to interpret social validity assessments. Rather than…

Missingness due to not-reached items and omitted items has received much attention in the recent psychometric literature. Such missingness, if not handled properly, would lead to biased parameter estimation, as well as inaccurate inference of examinees, and further erode the validity of the test. This paper reviews some commonly used IRT based…

Given its centrality to assessment, until the concept of validity includes concern for racial justice, such matters will be seen as residing outside the "real" work of validation, rendering them powerless to count against the apparent scientific merit of the test. As the definition of validity has evolved, however, it holds great…

An interesting geometric conservation problem is presented. Here proof is presented in a 'proof without words' style, with the aim of developing the reader's visual proof ability. The study of the task and its expansion is accompanied by a dynamic sketch to highlight the conservation property.

In this perspective, the authors critically examine "rater training" as it has been conceptualized and used in medical education. By "rater training," they mean the educational events intended to "improve" rater performance and contributions during assessment events. Historically, rater training programs have focused…

In this article Antti Moilanen assesses criticisms of Wolfgang Klafki's model of exemplary teaching made by Meinert Meyer and Hilbert Meyer and by Chi-Hua Chu. "Exemplary teaching" is a style of discovery-based teaching in which students study concrete examples of general principles in such a way that they acquire transferable knowledge…

This paper scrutinizes the increasing trend of using international large-scale assessment (ILSA) data for causal inferences in educational research, arguing that such inferences are often tenuous. We explore the complexities of causality within ILSAs, highlighting the methodological constraints that challenge the validity of causal claims derived…

Despite agreement about the central importance of validity for educational and psychological testing, consensus regarding the definition of validity remains elusive. Differences in the definition of validity are examined and reveals that a potential cause of disagreement stems from differences in word use and meanings given to key terms commonly…

In this article, we argue that automated scoring engines should be transparent and construct relevant--that is, as much as is currently feasible. Many current automated scoring engines cannot achieve high degrees of scoring accuracy without allowing in some features that may not be easily explained and understood and may not be obviously and…

This editorial explores the intersection of equity and validity in language assessment, focusing on language-minoritized test-takers. Recognizing that tests often perpetuate inequitable power dynamics, our special issue, 'Equity Orientations for Validity Frameworks: Exploring the Intersections of Language and Assessment for Language-Minoritized…

I consider recent attempts to establish standards, principles, and goals for artificial intelligence (AI) through the lens of educational measurement. Distinctions are made between generative AI and AI-adjacent methods and applications of AI in formative versus summative assessment contexts. While expressing optimism about its possibilities, I…

The purpose of this paper is to present a conversation about how impact has been seen and felt by youth and adult co-researchers in a long-term, school-based youth participatory action research (YPAR) project, "Courageous Conversations." To stay true to the epistemological commitments of YPAR, and in an effort to speak back to…
