The Application of Performance Feedback in Simulator Training: Its Effects on the Acquisition of Shiphandling Skills in Unfamiliar Waterways


Book Description

The purpose of this experiment was to determine whether providing performance feedback can improve the effectiveness of simulation in imparting shiphandling skills. Further, the relative effectiveness of two different levels of performance feedback was examined. Two groups of six subjects made eight simulator runs through the Valdez Narrows Channel. The 2nd, 3rd, 6th and 7th were training runs and the others were used as test runs. During the training runs one group called the augmented feedback group, was given a simulation display which highlighted the perceptual cues available to the subject. The other group, called the supplemental feedback group, had the same situation display and in addition was coached by an instructor after reach training run. During the test run, no feedback was provided. As a control, the data from six subjects who had performed the same task in a previous study were used. These subjects had received no enhanced feedback and were called the intrinsic feedback group. Learning was evaluated by comparing three groups on the test runs over a battery of shiphandling measures. Differences found between the groups prior to training were covaried out. A clear superiority in learning was exhibited by the augmented and supplemental feedback groups over the intrinsic feedback group using a one-way ANOVA procedure. The difference between the augmented and supplemental groups on individual performance measures were not significant.

Adaptive Feedback in Simulation-based Training


Book Description

Feedback is essential to guide performance in simulation-based training (SBT) and to refine learning. Generally outcomes improve when feedback is delivered with personalized tutoring that tailors specific guidance and adapts feedback to the learner in a one-to-on environment. Therefore, emulating by automation these adaptive aspects of human tutors in SBT systems should be an effective way to train individuals. This study investigates the efficacy of automating different types of feedback in a SBT system. These include adaptive bottom-up feedback (i.e., detailed feedback, changing to general as proficiency develops) and adaptive top-down feedback (i.e., general feedback, changing to detailed if performance fails to improve). Other types of non-adaptive feedback were included for performance comparisons as well as to examine the overall cognitive load. To test hypotheses, 130 participants were randomly assigned to five conditions. Two feedback conditions employed adaptive approaches (bottom-up and top-down), two used non-adaptive approaches (constant detailed and constant general), and one functioned as a control group (i.e., only a performance score was given). After preliminary training on the simulator system, participants completed four simulated search and rescue missions (three training missions and one transfer mission). After each training mission, all participants received feedback relative to the condition they were assigned. Overall performance on missions, knowledge post-test scores, and subjective cognitive load were measured and analyzed to determine the effectiveness of the type of feedback. Results indicate that: (1) feedback generally improves performance, confirming prior research; (2) performance for the two adaptive approaches (bottom-up vs.top-down did not differ significantly at the end of training, but the bottom-up group achieved higher performance levels significantly sooner; (3) performance for the bottom-up and constant detailed groups did not differ significantly, although the trend suggests that adaptive bottom-up feedback may yield significant results in further studies. Overall, these results have implications for the implementation of feedback in SBT and beyond for other computer-based training systems.







Minding the Helm


Book Description

Large ships transporting hazardous cargoes, notorious marine accidents, and damage to marine ecosystems from tanker spills have heightened public concern for the safe navigation of ships. This new volume offers a complete, highly readable assessment of marine navigation and piloting. It addresses the application of new technology to reduce the probability of accidents, controversies over the effectiveness of waterways management and marine pilotage, and navigational decisionmaking. The book also explores the way pilots of ships and tugs are trained, licensed, and held accountable. Minding the Helm approaches navigational safety from the perspectives of risk assessment and the integration of human, technological, and organizational systems. Air and marine traffic regulation methods are compared, including the use of vessel traffic services. With a store of current information and examples, this document will be indispensable to federal and state pilotage and licensing authorities and marine traffic regulators, the Coast Guard, pilot associations, and the shipping and towing industries. It will also interest individuals involved in waterway design, marine education, and the marine environment.




Simulation Training: Fundamentals and Applications


Book Description

Drawing on decades of industrial experience, this insightful and practical guide uses case studies and an interdisciplinary perspective to explain the fundamentals of simulation training to improve performance of high-risk professional activities. It seeks to identify those conditions under which simulation training has been shown to improve professional practice while employing extensive real examples. Simulation Training: Fundamentals and Application helps readers to develop their own synthesis of the simulation learning method and to use such training to enhance their skills and performance. Case studies demonstrate five specific theatres of professional practice - the nuclear-power industry, aeronautics, surgery, anesthesia and metallurgy – and then detailed analysis highlights the common factors and key results. The author’s background as a Human Factors Consultant, Physicist and Physiologist has enriched studies of humans in work situations, work organization and management and he has also been involved in pedagogical conception of experimental training on simulators based on his experience as a safety expert on nuclear power plant. The book is useful to practitioners, researchers and students, both in industry and in university. It is clearly cross disciplinary as it presents and discusses applications in engineering, professional practice (airline pilots) and medicine.

A Software Framework for Simulator Training Evaluation and Performance


Book Description

It is di cult to objectively measure performance of complex tasks such as a surgical operation and surgical simulators require the ability to evaluate performance whether to predict surgical outcome, determine competence, provide learning feedback, etc. With no standard software framework for collecting, analyzing and evaluating performance data for complex tasks in simulations, it is investigated whether a solution can be implemented that allows for custom data collection schemes, all while being general enough to be used across many simulation platforms and can be used in a simple simulator. It is also investigated whether the implemented framework can perform its functionality while leaving a small performance footprint on the simulator. Hierarchical task analysis is investigated as a means to decompose complex tasks into their simpler sub-tasks, where data can be collected for each task and evaluated. The framework is based on hierarchical task representation to allow robust performance data of a complex task to be collected and evaluated for any type of application. A client application is developed and allows for the generation of custom scenario parameters for the task, robust performance data collection and the ability to playback previous performances for evaluation purposes. It is shown that the implemented framework has a small peformance footprint and does not a ect the performance of the simulator that is using the framework for performance data collection and evaluation.




Fundamentals of Surgical Simulation

Medicine is currently at a tipping point in terms of how physicians in procedural based medicine are trained. Fundamentals of Surgical Simulation helps drive this change and is a valuable resource for medical trainers and trainees alike. For trainers, this book gives explicit theoretical and applied information on how this new training paradigm works thus allowing them to tailor the application of simulation training to their program, no matter where in the world they work. For the trainee, it allows them to see and understand the rules of this new training paradigm thus allowing them to optimize their approach to training and reaching proficiency in as efficient a manner as possible. For the simulation researcher, engineer and medical profession Fundamentals of Surgical Simulation poses some difficult questions that require urgent unambiguous and agreed answers.
