Preknowledge cheating jeopardizes the validity of inferences based on test results. Many methods have been developed to detect preknowledge cheating by jointly analyzing item responses and response times. Gaze fixations, an essential eye-tracker measure, can be utilized to help detect aberrant testing behavior with improved accuracy beyond using…

When researchers code behavior that is undetectable or falls outside of the validated ordinal scale, the resultant outcomes often suffer from informative missingness. Incorrect analysis of such data can lead to biased arguments around efficacy and effectiveness in the context of experimental and intervention research. Here, we detail a new…

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…

Based on the framework of testlet models, the current study suggests the Bayesian random block item response theory (BRB IRT) model to fit forced-choice formats where an item block is composed of three or more items. To account for local dependence among items within a block, the BRB IRT model incorporated a random block effect into the response…

Research Findings Research suggests children from low-income environments have vocabularies that differ from those of their higher-income peers. They may have basic knowledge of many words of which children from higher income environments have acquired sub- or supra-ordinate knowledge. This study sought to determine if children from low-income…

When self-administered surveys or questionnaires are administered, there is often a question of whether respondents have attended to the items in a thoughtful manner. This paper examines the results of three different surveys to investigate the occurrence of nonattending behaviors such as missing items, patterns that indicate lack of…

This guide is designed to help teachers create test items that measure a variety of higher level thinking abilities. Part One, "Foundations for Item Writing," provides a context for item writing. Chapter 1 provides an overview of the book and defines basic concepts, principles, and terminology. Chapter 2 integrates research literature to…

This study assumes that multiple choice test items generally provide the testee with several solutions, one of which is correct and the others of which are wrong. If pupils are unable to answer a question, one would expect that the wrong choices have equal chances of being selected. In many multiple choice items on stoichiometric calculation which…
