Chung, Gregory K. W. K.; Gyllenhammer, Ruth G.; Baker, Eva L. – National Center for Research on Evaluation, Standards, and Student Testing (CRESST), 2011
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…

Espinosa, Paul D.; Nagashima, Sam O.; Chung, Gregory K. W. K.; Parks, Daniel; Baker, Eva L. – National Center for Research on Evaluation, Standards, and Student Testing (CRESST), 2009
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…

Nagashima, Sam O.; Chung, Gregory K. W. K.; Espinosa, Paul D.; Berka, Chris; Baker, Eva L. – National Center for Research on Evaluation, Standards, and Student Testing (CRESST), 2009
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…

Goldschmidt, Pete; Martinez, Jose Felipe; Niemi, David; Baker, Eva L. – Educational Assessment, 2007
In this article we examine empirical evidence on the criterion, predictive, transfer, and fairness aspects of validity of a large-scale language arts performance assessment, referred to as the Performance Assignment (PA). We use multilevel models to avoid biased inferences that might result from the naturally nested data. Specifically, we examine…

Niemi, David; Wang, Jia; Steinberg, Diane H.; Baker, Eva L.; Wang, Haiwen – Educational Assessment, 2007
Validation of assessments intended to improve instruction and learning should include evidence of instructional sensitivity. This study investigated the instructional sensitivity of a standards-based ninth-grade performance assessment that required students to write an essay about conflict in a literary work. Before administering the assessment,…
