We revisit the empirically observed positive correlation between DIF and difficulty studied by Freedle and commonly seen in tests of verbal proficiency when comparing populations of different mean latent proficiency levels. It is shown that a positive correlation between DIF and difficulty estimates is actually an expected result (absent any true…

In this study, it was claimed that ROC analysis, which is used to determine to what extent medical diagnosis tests can be differentiated between patients and non-patients, can also be used to examine the discrimination of binary scored items in cognitive tests. In order to obtain various evidence for this claim, the 2x2 contingency table used in…

This study aimed to evaluate the item model fit by equating the forms of the PISA 2018 mathematics subtest with concurrent common items equating in samples from Türkiye, the UK, and Italy. The answers given in mathematics subtest Forms 2, 8, and 12 were used in this context. Analyzes were performed using the Dichotomous Rasch Model in the WINSTEPS…

Academic procrastination, the tendency to delay academic tasks without reasonable justification, has significant implications for students' academic performance and overall well-being. To measure this construct, numerous scales have been developed, among which the Academic Procrastination Scale (APS) has shown promise in assessing academic…

One of the most important indicators of artificial intelligence applications used to improve quality, effectiveness, and student success by optimizing instructional processes is readiness. Readiness is the cognitive, affective, and behavioral state of performing a behavior or using a technology. In this context, the development of a data…

The intricate relationship between representational competence and content knowledge in organic chemistry has been widely debated, and the ways in which representations contribute to task difficulty, particularly in assessment, remain unclear. This paper presents a multiple-choice test instrument for assessing individuals' knowledge of fundamental…

This study discusses the characteristics of test specifications (specs) and item writer guidelines (IWGs), their role in item development of English as a Second Language (ESL) reading tests, and the use of the CEFR for specs development. This mixed-method study analyzed specs, IWGs, tests, and the Pearson Test of English General test statistics.…

Completing questionnaires is a complex task in which multiple cognitive processes play an important role. Despite critiques of the reliability of questionnaires, our research strived to gain more insight into the process of completing questionnaires by using eye-tracking. We investigated how both the question and the categories of answers were…

This article presents generalizations of SIBTEST and crossing-SIBTEST statistics for differential item functioning (DIF) investigations involving more than two groups. After reviewing the original two-group setup for these statistics, a set of multigroup generalizations that support contrast matrices for joint tests of DIF are presented. To…

Free text answers to short questions can reflect students' mastery of concepts and their relationships relevant to learning objectives. However, automating the assessment of free text answers has been challenging due to the complexity of natural language. Existing studies often predict the scores of free text answers in a "black box"…

The present study examined the relationship between working memory capacity (WMC) and comprehension on a multiple text assessment from the ACT test for college preparedness in which texts are available during question answering. Specifically, it was of interest whether differences in relations would be seen across different question types. Only…

The idea of student engagement as a predictor of student success was first introduced by Alexander Astin (1974; 1984) who studied student involvement. The connection of student involvement and student success has led to the focus on student and how we measure it to ensure that institutions are doing all they can to improve outcomes. Nothing has…

E-assessments are becoming increasingly common and progressively more complex. Consequently, how these longer, more complex questions are designed and marked is imperative. This article uses the NUMBAS e-assessment tool to investigate the best practice for creating longer questions and their mark schemes on surveying modules taken by engineering…

The adaptive learning environment provides learning support that suits individual characteristics of students, and the student model of the adaptive learning environment is the key element to promote individualized learning. This paper provides a systematic overview of the existing student models, consequently showing that the Elo rating system…

Screening items for parameter drift helps protect against serious validity threats and ensure score comparability when equating forms. Although many high-stakes credentialing examinations operate with small sample sizes, few studies have investigated methods to detect drift in small sample equating. This study demonstrates that several newly…
