项目摘要

This research aims at developing the teaching materials to understand the property of wood. Three teaching materials were developed by this research. The nature that wood dimension changed by absorbing and releasing water was used in developing a smiling and tear-stained face teaching material and a water drinking bird teaching material. Interest and concern were shown when this teaching material was shown to a schoolchild.We noticed that much wood were being used for the musical instrument material and so on, and fundamental nature about the sound was examined. The sound pressure level of sound which rose when a blow does ten kinds of wood was measured with a noise meter, and the element of the sound was analyzed by a FFT analyzer as to the frequency. As that result, a high sound pressure level was shown with the hinoki material, red lauan material and the maple material. A peak magnitude was observed with much wood near about 2,000Hz in the frequency analysis. Next, the sensitivity e … More valuation was done for the ten kinds of same wood test materials when fifty testees were made to have a blow. The evaluation whose a red lauan material and a maple material were synthetically high was shown from the physical quantity by the meter and the amount of sense by the person. Two wood kinds were adopted as a material for the teaching material of the sound emission body to make a sound teaching material as this result. The difference was observed in the sound which rose remarkably by the form of the sound emission body. By making the plural sound emission body of different size in joint learning, the high effect on education was cleared.The microphotograph of the Japanese wood, the microphotograph of the cutting side, and so on were input to the computer, and a database about the wood was made. Then, when they were necessary, the system which could look them up was built. Class practice was done by using this system in the time of the junior high school technology, and high evaluation was taken as a teaching materials. It became clear that the knowledge of the wood was fixed for a junior high school student by using this database in the class of wood processing.We must strongly impress the various property of the wood on the ordinary consumer to promote manufacturing education, and the spread of wood must be widely active in the society through the lecture, the open class, the exhibition, and so on. It can be said that the teaching materials developed by this research is effective in these events. Less

本研究旨在开发教材，以了解木材的性质。本研究开发了三套教材。利用木材吸水、释水而改变尺度的性质，研制了笑脸、泪痕面教材和饮水鸟教材。当这本教材被展示给一个小学生时，我们表现出了兴趣和关注。我们注意到，许多木材被用于乐器材料等，并考察了声音的基本性质。用噪声计测量了10种木材受到打击时所产生的声压级，并用FFT分析仪分析了声音的频率成分。结果，扁柏材料、红柳桉材料和枫木材料显示出高声压级。在频率分析中，在2, 000 Hz附近观察到一个峰值幅度，其中有很多木材。其次，灵敏度E ...更多信息对10种相同的木材试验材料进行了50名受试者的冲击评价。红柳桉材和枫木材的综合评价从仪表物理量和人的感官量两个方面表现出来。采用两种木材作为用于声音发射体的教材的材料，从而制作声音教材。在通过声音发射体的形式显著升高的声音中观察到差异。通过在共同学习中制作不同尺寸的多个声音发射体，在教育上获得了高效果。将日本木材的显微照片、切削面的显微照片等输入计算机，制作了关于木材的数据库。然后，当他们是必要的，系统，可以查找他们建立。利用该系统在初中技术课进行了课堂实践，并作为教材进行了评价。利用该数据库在木材加工课上对初中生的木材知识进行了固定化的教学，使普通消费者对木材的各种属性有了深刻的印象，从而推动了制造业教育，通过讲座、公开课、展览会等形式，在社会上广泛传播木材知识，可以说，本研究所开发的教材在这些事件中是有效的。少
