應用X3D建製教學範例-以材料力學為例

Abstract

土木工程領域涵蓋甚廣，主要探討各種力學的應用。「力」是抽象的，在土木工程教學上，往往讓學習者於學習過程中遭遇困難，而自暴自棄。若透過3D的模擬，將「力」具體的表達出來，將有效提高學習者的學習效率及興趣。

本研究以材料力學為例，應用X3D建製3D動態教學範例，配合MathML顯示數學公式、科學記號，再使用XHTML網頁格式整合，最後套用CSS樣式表呈現網頁色彩、字型、背景……等屬性，使教學網頁更加豐富、生動。本研究教學的主題包含軸力、剪力、扭力、彎矩等四部份，以3D的方式模擬、展示，提供使用者學習。

本研究成果得知，以 3D方式呈現教學內容，可以增加使用者的學習效率，用較輕鬆的態度面對材料力學，達到電腦輔助教學的目的。

The Civil Engineering domain covers really broadly, mainly discusses the application for each mechanics. The "force" is abstract. In civil engineering education, often lets the learner feel difficult in the learning process and will be backward and have no urge to make progress. Per the simulation with 3D, if we can present the "force" specific that can enhance the learner's interest and study efficiency.

This research was given an example on Mechanics of Materials. It applies X3D to contribute the 3D dynamic teaching model and uses the MathML to show mathematical formula and scientific symbol. And integrates form by using XHTML homepage. Finally, shows the color, the font, and the background of the homepage by using CSS, makes it more vivid and abounding. The subject of the research teaching contains four parts, includes of the axial, the shear, the torsion and the moment. This research provides the users to learn by simulating and displaying in 3D way.

The results of this research show that, present the instruction per 3D, it might increase user's study efficiency. With a relaxed attitude to face the Mechanics of Materials, it can achieve the goal for computer assistance instruction.
