數學簡報系統的構圖環境之研究

Abstract

摘 要

數位落差是資訊科技融入教學最大的障礙，本研究嘗試建立一個輔助系統，提供教師們一個容易上手、功能強大的環境，以協助教師們開發數位教材。 本論文參考MathPS的系統架構，以OpenOffice為系統平台，融合它的簡報系統Presentation的特點，設計一套外掛於Presentation的構圖輔助系統，建立一個以數學教學為導向的工作環境。這個環境以幾何為理論基礎，以定位概念為構圖核心，嘗試讓使用者可以達到「模糊操作，準確定位」的目的。處理的對象包含點、線、面及相關數學繪圖物件等。系統結構主要分為四個單元：Viewer觀察物件屬性，Geometer操作幾何特性，Structure處理基本結構及複雜結構，Converter處理物件結構之轉換。 本研究所開發的構圖輔助系統，經過初步的測試，此一環境除可當作教師的工作平台之外，同時也可當作學生幾何教學活動及視覺設計的工作平台。這顯示本系統可以降低教師製作教材的門檻、節省時間及技術方面的成本，進而達到縮短教師數位落差的目的。對於未來推動數位內容視覺化有更大的助益。

Abstract Digital divide has been regarded as one of the largest obstacles to put information technology into teaching practice. This study attempts to build a support system for the provision of easy to access and powerful environment to assist the development and design of digital teaching material. Based on the structural frame of MathPS, this paper built the system platform of OpenOffice to take advantage of the features of its Presentation and designed a drawing support system plug-in Presentation to set up a math teaching oriented working environment. This environment centers on geometric theory and drawing positioning concept attempting to achieve the aim of “fuzzy operation and precise positioning.” The subjects in process include dot, line, dimension and relevant math drawing objects. System structure covers four units:：Viewer Properties, the Operation of Geometer, Basic Composition and Complicated Composition of Structure, and Structure of Converter. After the primary testing, the drawing support system developed by the Graduate is able to be used as the working platform of teachers and students for further geometric learning and visual designs. This indicates that this system is able to reduce the difficulty of teaching material making as well as saving more time and technical costs to close the digital divide. It is also believed that this system is also beneficial for the promotion of the visualization of digital contents.
