Study on Multimedianizing of Learning and Teaching Body Movement by Applying Bio-Mechanics

首先，我们拍摄了关于熟练工人和非熟练工人的两种手工刨床和手锯锯的视频图片。在拍摄完这些视频照片后，我们测量了手工锯切出的切屑的形状和厚度。从这些结果可以清楚地看出，技术熟练者和非技术熟练者之间的技术技能存在质的差异。研究结果对制作两种木工动作的多媒体学教软件具有重要意义。其次，我们拍摄了关于三项运动的视频图片。他们分别是剑道（日本剑术）的出拳动作、篮球的投篮动作和掷球动作。从这些视频图片中可以清楚地看出，熟练人员和不熟练人员在技术技能上的本质差异。研究结果对开发多媒体计算机学教学软件具有重要意义。利用这些成果和资料，我们成功地制作了三种多媒体计算机软件，用于木工肢体动作和运动肢体动作的学习和教学。多媒体计算机软件由语音、彩色图片和彩色动画组成。通过这些软件，学习者可以感兴趣地学习木工和运动中身体运动的许多要点。

First we took video-pictures about two kinds of planing by hand plane and sawing by hand saw about skilled and unskilled persons. After taking these video-pictures, we measured the shape and thickness of chip produced by hand sawing. From these results, it became clear that the difference of technical skill between skilled and unskilled person qualitatively. Also these results were significant to produce multimedia computer softwares of learning and teaching material about two woodworking motions.Second we took video-pictures about three items of sport motions. They were Shomen-uchi motion of Kendo (Japanese fencing), shoot motion of basketball and jarerin throw motion as to skilled and unskilled persons. From these video-pictures, it became clear that the qualitative difference of technical skill between skilled and unskilled persons. Also these results were significant to produce a multimedia computer software of learning and teaching material.By using these results and materials, we succeeded in producing three multimedia computer software to learn and teach about woodworking body motion and sport body motion. Three multimedia computer sofoware were consisted of voice, color picture and color animation. By these software, learner could study interestedly many important points of body motion about woodworking and sport.
