摘要

本研究旨在探討3D電腦繪圖技術應用於國小生活科技課程之可行性，3D技術的快速進展，繪圖工具之使用障礙已然降低；而Google等亦提供了3D繪圖軟體下載，其它市售軟體也提供試用版，故軟體取得非常容易。近年來國中小教學環境的改善，數位教學設施已明顯增多，但傳統工藝製作設施卻相形簡陋，而電腦輔助繪圖恰可將原先須應用手工製作之作品，轉化為數位設計與組裝之視覺化過程，進而呈現出3D化且包含材質與燈光陰影等的視覺模型，故科技教育強調實作的能力與歷程可於電腦輔助繪圖工具中獲得體現。英國的「設計與製作」教學課程及美國的k-12工程教育，其範疇早已發展至初等教育，台灣應重新評估並調整課程內容，以擴展學生的全球化視野。本研究以國小學童為研究對象，並發展教材以實施電腦輔助繪圖課程，該課程將進行設計與製作。評量工具包含自編的「電腦輔助繪圖軟體運用能力測驗」、「電腦輔助繪圖評量」等。研究結果發現：一、本研究所開發的小學電腦輔助繪圖課程，確可協助學生建立3D設計之繪圖概念並培養其應用能力。二、本研究於國小生活科技課程中，應用電腦輔助繪圖設計之學習成效良好並且確為可行，亦能激發學生正向之學習動機與興趣。最後，本研究根據研究結果提出相關建議。

The study was discussing feasibility that applies Computer Aided Drawing (CAD) technique to elementary technology education course. As the 3D CAD technology has been rapid and novelty development, many drawing tools already reduced the use of barriers. Now not only the CAD software of software provides many resources to get from the internet, even the software of genuine have been support trial version to many users.The present was great opportunity that applies 3D CAD technique course in elementary. The D&T (Design and Technology) teaching programs in the UK and the K-12 EiE (Engineering is Elementary) programs in the USA are cases indicating that technological development has extended to primary schools. Therefore, it is crucial for schools in Taiwan to re-evaluate and adjust the curricula and contents to cope with the challenges of the new era.The 30 students in the fifth grade were chosen as the research subject. The CAD instruction materials was developed by the researcher, due were instruction weekly for study. Both qualitative and quantitative data were collected and sorted during the research. The findings are as follows:1. This research has developed CAD technology education course suitable for the fifth grade students in primary schools. In addition that can bring up the concepts of design and drafting for students.2. The study has achieved better learning effects of CAD instruction in technology education course. Besides, the effects have inspired better learning motives.
