We investigated whether and to what extent different scoring instructions, timing conditions, and direct feedback affect performance and speed. An experimental study manipulating these factors was designed to address these research questions. According to the factorial design, participants were randomly assigned to one of twelve study conditions.…

The report is the first systematic evaluation of the sentence equivalence item type introduced by the "GRE"® revised General Test. We adopt a validity framework to guide our investigation based on Kane's approach to validation whereby a hierarchy of inferences that should be documented to support score meaning and interpretation is…

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…

Items previously described as "negatively worded" are redefined as "connotatively inconsistent" because this term has a broader base for generalization. Using generalizability theory with a sample of 102 graduate students, the study showed that connotatively consistent and reversed connotatively inconsistent items were not…

The appropriate analysis of students' responses to an assessment is an essential step in improving the quality of the assessment itself as well as staff teaching and student learning. Many academics are unfamiliar with the formal processes used to analyze assessment results; the standard statistical methods associated with analyzing the validity…

The feasibility of using item response theory (IRT) as a psychometric model for the Graduate Record Examination (GRE) Aptitude Test was addressed by assessing the reasonableness of the assumptions of item response theory for GRE item types and examinee populations. Items from four forms and four administrations of the GRE Aptitude Test were…

Reliability and validity of 4-point and 6-point scales were assessed using a new model-based approach to fit empirical data from 165 graduate students completing an attitude measure. Results suggest that the issue of four- versus six-point scales may depend on the empirical setting. (SLD)

Evaluated a computer-delivered response type for measuring quantitative skill, the "Generating Examples" (GE) response type, which presents under-determined problems that can have many right answers. Results from 257 graduate students and applicants indicate that GE scores are reasonably reliable, but only moderately related to Graduate…

"Item models" (LaDuca, Staples, Templeton, & Holzman, 1986) are classes from which it is possible to generate/produce items that are equivalent/isomorphic to other items from the same model (e.g., Bejar, 1996; Bejar, 2002). They have the potential to produce large number of high-quality items at reduced cost. This paper introduces…

The study evaluated the invariance of the construct validity and thus the interpretation of Graduate Record Examinations (GRE) Aptitude Test scores. A systematic procedure for investigation of test bias from a construct validity frame of reference was developed and applied. Invariant construct validity was defined as similar patterns of loadings…

We describe the item modeling development and evaluation process as applied to a quantitative assessment with high-stakes outcomes. In addition to expediting the item-creation process, a model-based approach may reduce pretesting costs, if the difficulty and discrimination of model-generated items may be predicted to a predefined level of…
