國中生活科技正投影圖學課程應用3D電腦輔助演示之可行性研究

Abstract

本研究旨在探討於國中生活科技圖學課程之正投影單元中，使用3D電腦圖形來進行教學演示之可行性，分別針對教師及學生部分進行探討。在教師方面，從文獻整理出教師進行資訊融入教學的問題，再以此檢核3D電腦圖形輔助演示之可行性；在學生方面，以教學實驗的方式，探討比較不同演示方式之學生之學習結果，藉以瞭解學生之接受程度情形。根據兩部分結果，得出3D電腦圖形輔助演示之教學可行性。 而本研究獲致以下結論： 一、使用3D電腦圖形演示方法於生活科技正投影圖學課程中，以目前環境對於教師使用軟體與設備的支援度是具備的，並且由於其在資訊融入教學的層次上偏屬於教師端的出發角度，對於教師的教學準備負擔是低的。因此，在教師方面，在意願配合下是具有可行性的。 二、使用3D電腦圖形演示，教師在能力上必須具備3D電腦圖形之概念與操作，因此對相關能力缺乏之教師，必須有接受電腦圖形資訊的訓練進修的意願。新一代生活科技教師，由於已接受過電腦資訊素養的相關培育課程，因此在使用3D電腦圖形演示於課程的門檻較低。 三、在學生方面，學生對於使用3D電腦圖形演示方法的接受度，從與實體模型演示實驗組別的學習結果來看，兩者在後測成績結果並無差異，因此兩組學生對於兩教學方式的接受度是相同的，因此，可推論採用3D電腦圖形演示的方法在學生方面的因素是可行的。The purpose of this study were to understand the feasibility of demonstrating 3D computer graphics on orthographic projection drafting courses at high school. It was made from two parts: the caused problem for teachers and the student’s acceptance. We collected the teacher’s problems of integrating information technology into teaching and checked if it would be problems when using demonstrating 3d computer graphics on orthographic projection drafting courses at high school. Moreover, We made an experiment of two different teaching methods to gain the students’ achievements, so as to understand students’ acceptability. Then made conclusions of feasibility base on the information. The conclusions as the follows: 1.）The Software and equipments can be provided in current school conditions. And the method of demonstrating 3D computer graphics is a basic way when integrating information technology into teaching. For teachers, the loads are low. It is feasible when teachers will. 2.）Teachers must know the conception and manipulation of 3D software when demonstrating 3D computer graphics on courses. The teacher lacked needs to be willing to upgrade. New technology teachers had learned them at teacher’s school, for them, it would not be hard to integrating information technology into teaching. 3.）There were no significant difference among the post-test scores in experimental group and controlled group. It means the method of demonstrating 3D computer graphics can be accepted by students as Solid demonstrating.
