Therefore, the study is significant both theoretically and practically. As a result, the studying aim of this paper is to establish a practical and complete system for the prediction of ship maneuvering motion, taking into account of the influence of the environmental factors, such as the wind, wave and current, establish a practical and complete system for the prediction of ship maneuvering motion. In this paper, the OpenGL virtual reality simulation technique is introduced into the field of ship maneuver and control, and using the MMG mathematical model, the three dimensional dynamic simulation system of the ship motion is established and good results are achieved. In the process of the system development, firstly, the maneuvering motion equations for ship in the still water are established, based on the MMG module mathematical model and serial experimental result. After compiling the program, the calculation results are compared with the experimental data, the coherence between them validate the mathematical model.

在系统开发过程中，首先采用MMG分离式数学模型及相关的系列化试验结果，建立单桨单舵海洋运输船舶在静水中的船舶操纵运动方程，并编制计算程序，经与试验结果比较，证实了计算结果的正确性；为了解MMG数学模型中模型参数变化对操纵性指数的影响程度，作者在上述已有程序基础上，对有关模型参数进行偏移修正，探讨了相应参数变化后的操纵性指数，对船舶操纵性指数对模型参数的灵敏度进行了详细的分析与探讨，所得结论与工程实际相吻合，具有实际应用价值，并为进一步提高船舶操纵性预报的精度打下了基础；然后，在已有的船舶静水操纵运动模型基础上，考虑双桨双舵的影响，建立了内河双桨双舵船舶的操纵运动模型；最后，综合考虑风浪流作用力的影响，进行了船舶的操纵运动仿真计算。

The purposes of this study were:(1) to explore whether there were interactions between "Feedback" and "Goal-setting" on both students' mathematical performance and test anxiety;(2) to compare the differences of students' mathematical performance and test anxiety between students' self-set goals and teacher-assigned goals;(3) to compare the differences of students' mathematical performance and test anxiety between students of different predicting abilities.

本研究的目的有三：一为探讨「回馈方式」与「目标设定」二因子之间是否有交互作用效果存在；二为比较学生自订目标与教师指定目标间，学生在数学作业表现或是数学测试焦虑分数上的差异；三为分析学生自订目标中，不同预测能力的学生在数学作业表现或是数学测试焦虑分数上的差异。本研究的受试来自台北市、台北县六所国小261名五年级学生，使用的工具有数学乘除法测验及数学测试焦虑量表。
