操舵操船に関する視覚教材の開発とその教育効果

Abstract

The fundamental knowledge and understanding about ship handling are indispensable for students of navigation course. Especially in steering, different movement such as kick, turn, heel, will arise simultaneously for a short time in a transition stage until it goes into steady turning motion immediately after taking rudder. In order to realize more effective education about steering, we developed a simulation system as an educational teaching material, which enables display of many phenomena in accordance with turning motion. In this integrated simulation system (ISS) of steering, output data obtained from a shiphandling simulator were processed and displayed on the animation, which is easy to understand visually. Five sub-windows are displayed on the main screen of the ISS of steering : hull movement and vector ; locus of hull ; position of pivoting point ; heeling ; time series data such as ship's speed, turn rate, heel angle, drift angle and transition of pivoting point. Concerning with the educational effect of this steering simulation system, the experiment was conducted and the effectiveness was verified by the test and the questionnaire. It can be said that the group, which received the lecture using the ISS of steering was able to understand the simultaneity more correctly about the phenomenon simultaneously generated in the initial stage of turning motion comparing with the group, which received the lecture in classroom without using this simulation system.
