Drape程式的編修及應用

Abstract

Drape(DRAwing Programming Environment)是荷蘭教授Mark Overmars為兒童學習程式設計而開發出來的繪圖軟體，相當易學易用，研究者希望能利用此軟體教導國中生學習基本的程式設計概念。因為原作者不再開發此軟體，為了學習上的需要，經原作者同意後研究者將軟體英文介面加以中文化，並對程式原始碼加以修改，增加數學函數功能及顯示變數的功能，以提高其應用的廣度。而經過研究者教授國中生Drape軟體後發現，學生有能力使用指令來畫圖，多數學生肯定此軟體的功能，透過教學省思後研究者也嘗試利用Drape程式設計解題活動，作為Drape解題應用之初探。透過功能的增加及修改，使原來處理整數運算為主的程式也能夠處理實數運算，原來以繪圖為主的程式也能夠進行數值方法計算。 根據研究結果，研究者認為：一、Drape軟體可以作為認識程式設計之入門軟體。二、Drape可以作為學習數學之輔助工具。後續研究上，Drape軟體可在數學函數、運算精確度、對話框與陣列變數上作編修加強。

Drape (DRAwing Programming Environment) is a drawing software developed by Mark Overmars. Originally it was used to teach children programming design. The researcher found it is easy to use and learn, and thought to use it to teach junior high school students basic programming design concept. Because Overmars will not develop the software anymore, for research purpose the researcher received his agreement to modify the source code. Reflections from teaching and feedback from students, Drape was modified to increase its appropriateness. Now, Drape was modified into a Chinese interface, and a few basic mathematics functions and setting variables were added to extend its applications. After these modifications, Drape can also be used to do numeric analysis and solve problems. Some examples were discussed in chapter 4. Most students gave positive responds to the use of Drape. The researcher believes that Drape can be used as a basic programming design software for junior high school students and as a tool to learn mathematics. Improving prevision of operations, and adding functions such as showing a dialogue box, setting array variable and other advance mathematics functions can be the directions for future study.
