In this study, we compared the effects of simulator-based virtual ultrasound scanning practice to classroom-based hands-on ultrasound scanning practice on participants' knowledge of FAST window quadrants and interpretation, and on participants' performance on live patient FAST exams. Twenty-five novice participants were randomly assigned to the…

Measures of rifle marksmanship skill and performance were developed using a prototype instrumented laser-based training system. Measures of performance were derived from laser strikes on a video-projected target. Measures of rifle marksmanship skill--breath control, trigger control, and muzzle wobble--were developed from shooters' breathing and…

The main purpose of this study was to examine the effects of the Reading Apprenticeship professional development program on several teacher and student outcomes, including effects on student learning. A key part of the study was the use of an enhanced performance assessment program, the Integrated Learning Assessment (ILA), to measure student…

The goal of this report was to test the use of sensor-based skill measures in evaluating performance differences in rifle marksmanship. Ten shots were collected from 30 novices and 9 experts. Three measures for breath control and one for trigger control were used to predict skill classification. The data were fitted with a logistic regression…

Assessment of complex task performance is crucial to evaluating personnel in critical job functions such as Navy damage control operations aboard ships. Games and simulations can be instrumental in this process, as they can present a broad range of complex scenarios without involving harm to people or property. However, "automatic"…

This cut score modeling study investigated whether changing the cut scores of language arts performance assessments (PAs) would differentially affect subgroups of students. Based on a data set of 227,817 students, hierarchical logistic regression analysis revealed that no sub-groups of students were found to have a higher or lower possibility of…

Assessment models support the design of quality performance assessments. Assessment tools are being developed to enable easy and effective application of the models. Based on representations of assessment design knowledge and domain knowledge in ontologies, the tools provide guidance to assessment designers, and through constraint processing check…

The purpose of this report is to provide the theoretical rationale for the approach to academic language that was adopted to meet the research goals of the second phase of this project as well as to report on the results from the pilot training program that was developed to create the conditions under which varying levels of direct instruction in…

The main goal of this report is to present evidence on the predictive validity of an English language arts (ELA) performance assessment (PA) administered in Grades 2-9 in a large urban school district. To account for the hierarchical structure of the data (students are nested within schools), we employed hierarchical linear modeling (HLM) to…
