Research has suggested that changing one's answer on multiple-choice examinations is more likely to lead to positive academic outcomes. This study aimed to further understand the relationship between changing answer selections and item attributes, student performance, and time within a population of 158 first-year medical students enrolled in a…

This study investigates how interactive features embedded in the illustrations of storybook apps influenced young readers' story enjoyment and comprehension. Kindergartners and second graders (N = 91) were randomly assigned to read storybook apps in an interactive or noninteractive condition. Findings showed that children's self-reported enjoyment…

As a high-stakes standardized test, IELTS is expected to have comparable forms of test papers so that test takers from different test administration on different dates receive comparable test scores. Therefore, this study examined the text difficulty and task characteristics of four parallel academic IELTS reading tests to reveal to what extent…

The POWERSOURCE[c] intervention is intended as a generalizable and powerful formative assessment strategy that can be integrated with any mathematics curriculum. POWERSOURCE[c] includes both a system of learning-based assessments and an infrastructure to support teachers' use of those assessments to improve student learning. The core undertaking…

To rule out the need for a two-parameter item response theory (IRT) model during item analysis by Rasch models, it is important to check the Rasch model's assumption that all items have the same item discrimination. Biserial and polyserial correlation coefficients measuring the association between items and restscores are often used in an informal…

In this research, we investigated the suitability of implementing "e-rater"® automated essay scoring in a high-stakes large-scale English language testing program. We examined the effectiveness of generic scoring and 2 variants of prompt-based scoring approaches. Effectiveness was evaluated on a number of dimensions, including agreement…

This comprehensive "Handbook" focuses on the most used polytomous item response theory (IRT) models. These models help us understand the interaction between examinees and test questions where the questions have various response categories. The book reviews all of the major models and includes discussions about how and where the models…

Reviews the most recent version of the BILOG computer program, which estimates item and trait level parameters for the one-, two-, and three-parameter logistic unidimensional Item Response Models for dichotomously scored data. Finds this version useful. (SLD)

Reports on the potential problems in scoring responses to sequencing tests, the development of a computer program to overcome these difficulties, and an exploration of the value of scoring procedures. (Author/VWL)

Differential item functioning (DIF) is an important consideration in assessing the validity of test scores (Camilli & Shepard, 1994). A variety of statistical procedures have been developed to assess DIF in tests of dichotomous (Hills, 1989; Millsap & Everson, 1993) and polytomous (Penfield & Lam, 2000; Potenza & Dorans, 1995) items. Some of these…

A multi-purpose, multi-user evaluation system was designed to improve the quality of the reporting of information gathered in testing and evaluation practices. One part of the system, the reporting system for information resulting from a district standardized testing program, was described. The Student-Problem Package software was modified to…

This paper describes teacher usage of the microcomputer programs Test Analysis Package (TAP) and Student Problem Package (SPP) to analyze students' test item responses. These methods of organizing, analyzing, and reporting test results have proven useful to classroom teachers. The TAP consists of four integrated microcomputer programs to edit,…
