Fidelity-adaptive sonar modeling and simulation for game-based learning

Abstract

Simulation of sonar systems is now a component of training regimens of navies worldwide. Improvements in understanding of physical phenomena, together with better models and innovations in simulation techniques have enabled simulation- based training to augment in-situ training. Yet, the ability to sustain such progress is compromised by a critical shortage of students choosing to study for careers in science, technology, engineering and mathematics (STEM). In this work, algorithms and techniques first developed for sonar modeling and simulation are adapted for development of an educational game aimed at teaching secondary-school students how sound is used to explore and communicate in the undersea environment. This requires a new paradigm in modeling and simulation, as fidelity requirements must be evaluated in terms of pedagogical goals. While simulations and the underlying models must accurately represent functional relationships in the physical world as those concepts are being taught, they must sometimes exclude unnecessary or confusing levels of detail. Therefore, fidelity must be adaptive both to the particular lesson and to the level of proficiency of the learner. In this paper, use of modeling and simulation and selection of models for use in the educational game are described together with techniques for interfacing simulations and games. © 2012 Acoustical Society of America.
