Multimedia technology offers a more interactive approach to instruction than the traditional classroom lectures. Through computer-aided instruction (CAI), a number of teaching styles can be used that take into account the different preferences of the students. The Biomechanics Tutorial program that the authors have written is a CAI that incorporates audio, video, simulations, and graphics to: review concepts of mechanics (kinematics and kinetics of interconnected rigid bodies), familiarize students with functional anatomy, and allow students to interactively evaluate the law of mechanics applied to physical performance of activities modeled by a set of biomechanical models of the joints. Principles of ergonomics are reinforced by enabling the student to perform numerous numerical experiments within the context of workplace or task redesign and see the real time consequences of these alterations. For example, the task of holding a load is simulated by allowing the student to change elbow and shoulder angles and the orientation and magnitude of the load. The consequences of these in terms of required muscle forces and joint reaction forces at the elbow and shoulder will be updated on the screen. The detailed rationale of developing this Biomechanics Tutorial which integrates a variety of learning styles will be presented.
与传统课堂讲授相比，多媒体技术为教学提供了一种更具互动性的方法。通过计算机辅助教学（CAI），可以采用多种教学方式，这些方式考虑到了学生的不同偏好。作者编写的生物力学教程程序就是一种CAI，它结合了音频、视频、模拟和图形，以：复习力学概念（相互连接刚体的运动学和动力学），使学生熟悉功能解剖学，并让学生交互式地评估应用于由一组关节生物力学模型模拟的活动身体表现的力学定律。通过让学生在工作场所或任务重新设计的背景下进行大量数值实验，并查看这些改变的实时结果，强化了人体工程学原理。例如，通过让学生改变肘部和肩部角度以及负载的方向和大小来模拟握持负载的任务。这些操作在肘部和肩部所需肌肉力量和关节反作用力方面的结果将在屏幕上更新。本文将介绍开发这种整合多种学习方式的生物力学教程的详细原理。
