Lord's (1980) equity theorem claims observed-score equating to be possible only when two test forms are perfectly reliable or strictly parallel. An analysis of its proof reveals use of an incorrect statistical assumption. The assumption does not invalidate the theorem itself though, which can be shown to follow directly from the discrete nature of…

This special issue brings together research in multilingualism within applied linguistics to delineate conceptualizations of multilingualism as constructs amenable for classroom and standardized testing systems operations. Specifically, for language testing and assessment, there have been multiple calls for the field to embrace multilingual…

What is the best way of discovering the underlying structure of a causal system composed of multiple variables? One prominent idea is that learners should manipulate each candidate variable in isolation to avoid confounds (sometimes known as the control of variables [CV] strategy). We demonstrate that CV is not always the most efficient method for…

Evolution causes biological and cultural diversity through adaptation to environmental conditions. This idea forms the cornerstone of recent research on the ecological origins of innovation and creativity, advanced prominently by Van de Vliert and Murray (2018) as the "ecotheory of creativity." Van de Vliert and Murray propose that heat…

The study examined Social Studies teachers' perception of values clarification strategy for curbing examination mal-practice in upper basic schools in Ilorin Metropolis, Kwara state. The study adopted a descriptive survey design. The population for this study was all teachers in Upper Basic schools while the target population was Upper Basic…

The Mantel-Haenszel delta difference (MH D-DIF) and the standardized proportion difference (STD P-DIF) are two observed-score methods that have been used to assess differential item functioning (DIF) at Educational Testing Service since the early 1990s. Latentvariable approaches to assessing measurement invariance at the item level have been…

Forced-choice (FC) measures are becoming increasingly common in the assessment of personality for high-stakes testing purposes in both educational and organizational settings. Despite this, there has been relatively little research into the reliability of scores obtained from these measures, particularly when administered as a computerized…

Calibration of an item bank for computer adaptive testing requires substantial resources. In this study, we investigated whether the efficiency of calibration under the Rasch model could be enhanced by improving the match between item difficulty and student ability. We introduced targeted multistage calibration designs, a design type that…

This article explores the comparability of assessment tools under different format conditions. Prior studies have not considered the interaction of format and device on time to complete an assessment and have instead treated each of them separately with conflicting results. This study assesses, by linear regressions using web-based data, the…

The purpose of the current study was to examine the differences between number and types of administration and scoring errors made by administration method (digital/Q-Interactive vs. paper-and-pencil) on the Wechsler Intelligence Scales for Children (WISC-V). WISC-V administration and scoring checklists were developed in order to provide an…

Formal empirical assessments of replication have recently become more prominent in several areas of science, including psychology. These assessments have used different statistical approaches to determine if a finding has been replicated. The purpose of this article is to provide several alternative conceptual frameworks that lead to different…

Compared with other learning strategies, retrieval practice seems to promote superior long-term retention. This has been found mostly in conditions where learners take tests after being exposed to learning content. However, a pre-testing effect has also been demonstrated, with promising results. This raises the question, for a given amount of time…

The rapid shift to an online instructional mode necessitated by COVID-19 has been a formidable challenge for most institutions but particularly for those in which online learning was not widely implemented before the pandemic. Assessment has been an additional challenge, coupled with the accreditation requirements that higher educational…

Recent research has found that maintaining an item in working memory improves subsequent long-term memory performance. The present study explored the role of working memory consolidation in long-term recognition. Participants completed a stimuli-identification task followed by a surprise delayed recognition task. Participants first identified…

Trust-based e-assessment systems are increasingly important in the digital age for both academic institutions and students, including students with special educational needs and disabilities (SEND). Recent literature indicates a growing number of studies about e-authentication and authorship verification for quality assurance with more flexible…
