The Test Design And Evaluation

Decent Essays

Test design and evaluation Participants 16 drilling personnel working at an oil and gas corporation in Perth will be recruited. The recruitment is restricted only to one company to minimise confounds due to different company regulation and training. These personnel consist of eight ‘experts’, with more than five years working experience in drilling and eight ‘novice,’ with less than five years drilling experience. This sample size was chosen based on high internal consistency and predictive validity in a prior study for testing practical trauma skills (Hogan et al. 1996), with coefficients mentioned in previous section. Design The design of this test is two-level between-subject design, with SA scores as the dependent variable and expertise (expert, novice) as the independent variable. Materials and Measures Software Pressure Upon Rig Simulator - SPURS (Bamfort & Wang, 1994). This video-based drilling simulator is displayed in a personal computer, which has been equipped by custom software and interface equipment connected to mud pumps. The scenario is made corresponding to the goal of test: solving formation kicks. The input from the rig equipment will be decoded to the simulator through interface, and the output will be exerted to the real rig gauge. The simulation lasts for two hours, where three freezes consists of SAGAT items are randomly introduced. This scenario was chosen because it possesses good predictive validity when compared with workers’ real well test
