Development of Learning Support System for Considering Analysis Model on Dynamics through Design-Production-Experiment of Real Model

重要的是要知道如何运用科学技术知识来解决技术设计问题，如何学习“制造”的基本原理。为阐明这一点，开发了《动力学与设计》电子学习教材。具体的设计主题是设计一款可以举起150克质量的汽车模型。本设计主题包括动力学和技术知识：力、力矩、摩擦力、重心、电机和齿轮。利用该教材，理工学院、教育学院的技术课程和理工高中的学生学习了动力学的基础知识和汽车模型的设计。实践结果表明，学生在设计汽车模型时，需要掌握动力学基础。如果学生不掌握动力学基础，他们就不能从动力学的角度分析和解决汽车模型的问题。虽然这本教材对学生来说很难，但他们对这门课很感兴趣，也很努力。他们用教材解决了这个设计题目。开发的教材是支持设计学习的有效工具，学生解决了用基于实验的归纳教材、基于基础理论分析的演绎教材和用物理模型进行模拟来设计汽车模型的问题。教材中需要包含解决问题所需的各种信息，通过传授动力学基础和实际应用相结合的方式，使学生有效地掌握动力学的基本知识。开发的集基础与应用于一体的网络学习教材是一种实用的技术教育教学手段。

It is important to know how to solve technical design subjects through application of the knowledge of science and technology and how to learn essential principles of 'manufacturing'. E-learning teaching materials of dynamics and design were developed to clarify these. The concrete design subject is designing a car model that can raise a 150-g mass. This design subject includes knowledge of dynamics and technology : force, moment of force, friction, centre of gravity, motors, and gears. Students of the college of technology, the technology course in education faculty and the science-technology high school learned the basis of dynamics and the design of a car model using of this developed teaching material. Results of practice clarified the followings.Students need to master the basis of dynamics when they solve the problem of designing a car model. If students don't master the basis of dynamics, they can't analyze the problem of car model from the viewpoint of dynamics and solve it. Although this teaching material was difficult for students, they were interested in and grappled with this subject. They solved this design subject using the teaching material. The developed teaching materials are effective tools to support the design learning.Students grappled with the problem solving of designing a car model using all teaching materials of inductive teaching materials based on an experiment, deductive teaching materials through analysis based on fundamental theories and the simulation using physical models. The teaching material needs to include various kinds of information which is necessary to solve the problem.Students can master the basic knowledge of dynamics effectively through teaching the basis of dynamics and the practical application at the same time. The developed e-learning teaching material integrated the basis and the application is a useful teaching method for technology education.
