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 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 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…

In this study we examined the role of anxiety on novices' performance on the psychomotor task of rifle marksmanship. The stages-of-skill-development model suggests that aptitude influences performance while learning a skill; however, the model does not address the role of affect. Assessments for state anxiety and state worry were administered to…
