Unidimensionality is an important assumption of measurement but it is violated very often. Most of the time, tests are deliberately constructed to be multidimensional to cover all aspects of the intended construct. In such situations, the application of unidimensional item response theory (IRT) models is not justifieddue to poor model fit and…

The present study examines the relative importance of attributes within and across items by applying four cognitive diagnostic assessment models. The current study utilizes the function of the models that can indicate inter-attribute relationships that reflect the response behaviors of examinees to analyze scored test-taker responses to four forms…

In this study, we revised the "Metacognitive Awareness of Reading Strategies Inventory" (MARSI), a self-report instrument designed to assess students' awareness of reading strategies when reading school-related materials. We collected evidence of structural, generalizability, and external aspects of validity for the revised inventory…

This paper provides a summary of a novel and integrated way to think about the item response models (most often used in measurement applications in social science areas such as psychology, education, and especially testing of various kinds) from the viewpoint of the statistical theory of generalized linear and nonlinear mixed models. In addition,…

The purpose of this study is to validate a test anxiety scale for Italian students. The scale is part of a questionnaire administered after the students' annual competence test by the National Institute for the Educational Evaluation of Instruction and Training (INVALSI). The aim of the scale is to explore the anxiety levels of Italian students…

Latent class modeling procedures were used in exploratory and confirmatory analyses of the prerequisite relations among five types of text-based inference question tasks for good and poor sixth-grade readers. All tasks types provided separate manifestations of the same underlying attribute for both good and poor readers. (Author/BS)

Multiple-choice reading comprehension items from a conventional, norm-referenced reading comprehension test were successfully analyzed using a simple latent class model. Results support the use of latent class, state mastery models with more heterogenous item pools than has been previously advocated. (Author/PN)

A model of verbal performance was developed which defined cognitive processes thought to underlie performance on the Word Knowledge and Paragraph Comprehension subtests of the Armed Services Vocational Aptitude Battery (ASVAB). The items from two forms of these ASVAB verbal subtests were rated on five conceptualized cognitive storage processes:…

Recent assessment research joining cognitive psychology and psychometric theory has introduced a new technology, item generation. In algorithmic item generation, items are systematically created based on specific combinations of features that underlie the processing required to correctly solve a problem. Reading comprehension items have been more…
