Changepoints are abrupt variations in a sequence of data in statistical inference. In educational and psychological assessments, it is pivotal to properly differentiate examinees' aberrant behaviors from solution behavior to ensure test reliability and validity. In this paper, we propose a sequential Bayesian changepoint detection algorithm to…

An achievement test was prepared to determine students' caricature reading skills. In the first draft of the achievement test, 32 test items and four choices were prepared for each question. The item analysis of the data obtained from the pre-application was made and the internal consistency coefficient (KR-20) was calculated as 0.67 for the…

This cognitive interview study aims to improve the content validity of a newly developed reading motivation instrument for English learners. Previous research has shown there is a significant need for survey developers to conduct cognitive interviews to ensure that in real world settings survey respondents interpret the items as the framers…

We investigated how item formats influence test takers' response tendencies under uncertainty. Adult participants solved content-equivalent math items in three formats: multiple-selection multiple-choice, grid with forced-choice (true-false) options, and grid with non-forced-choice options. Participants showed a greater tendency to commit (rather…

The present study tries to investigate the fairness of an English reading comprehension test employing Kunnan's (2004) test fairness framework (TFF) as the most comprehensive model available for test fairness. The participants of this study comprised 300 freshman students taking general English course chosen based on the availability sampling,…

This paper investigates the validation of the computer-based listening subtest in the "Certificate of English for Primary Teachers" (CEPT), which is addressed to in-service primary teachers who work in state Italian schools. Since 2004, these teachers, specialists in other subjects, have been asked by the Italian Ministry of Education to…

Comparatively little research exists on single-skill math (SSM) curriculum-based measurements (CBMs) for the purpose of monitoring growth, as may be done in practice or when monitoring intervention effectiveness within group or single-case research. Therefore, we examined a common variant of SSM-CBM: 1 digit × 1 digit multiplication. Reflecting…

This review of the literature analyzed twenty-eight survey instruments that were designed and validated by different researchers in order to measure teachers' technological pedagogical content knowledge. The analysis was done to find out the nature and synthesis of survey items across domains of the technological pedagogical content knowledge…

This study focuses on developing the new level of scientific argumentation skills and new items that are feasible and valid for used. There are 195 science students at Islamic State School 1 (MAN 1) Yogyakarta as participant in this study. Random sampling technique was used from the three schools of Islamis State School (MAN) in Yogyakarta,…

In this digital ITEMS module, Dr. Jeffrey Harring and Ms. Tessa Johnson introduce the linear mixed effects (LME) model as a flexible general framework for simultaneously modeling continuous repeated measures data with a scientifically defensible function that adequately summarizes both individual change as well as the average response. The module…

Data simulation and Monte Carlo simulation studies are important skills for researchers and practitioners of educational and psychological measurement, but there are few resources on the topic specific to item response theory. Even fewer resources exist on the statistical software techniques to implement simulation studies. This article presents…

Assessments that aim to evaluate student understanding of chemical reactions and reaction mechanisms should ask students to construct written or oral explanations of mechanistic representations; students can reproduce pictorial mechanism representations with minimal understanding of the meaning of the representations. Grading such assessments is…

Medical school selection is currently in the paradoxical situation in which selection tools may predict study outcomes, but which constructs are actually doing the predicting is unknown (the 'black box of selection'). Therefore, our research focused on those constructs, answering the question: do the internal structures of the tests in an…

In large-scale educational assessments, it is generally required that tests are composed of items that function invariantly across the groups to be compared. Despite efforts to ensure invariance in the item construction phase, for a range of reasons (including the security of items) it is often necessary to account for differential item…

Research has shown that the context of practice tasks can have a significant impact on learning, with long-term retention and transfer improving when tasks of different types are mixed by interleaving (abcabcabc) compared with grouping together in blocks (aaabbbccc). This study examines the influence of context via interleaving from a psychometric…
