程式設計電子教科書之輔助理解功能開發

Abstract

本研究旨在發展一套能輔助理解的程式設計電子教科書系統，並了解學生使用此一系統之成效。系統功能重點在於發揮電子媒體可動態改變圖文屬性的特色，在學生閱讀教材的過程中，將說明文字與被說明對象之間的關連性清楚標示出來，使得文字說明與圖解、程式碼能緊密結合，以達到輔助閱讀與理解的效果。輔助功能設計完成後，我們採用改良式的實驗組與控制組前測、後測的實驗設計，針對高中生進行實驗研究，同時以觀察單記錄學生使用本系統時的閱讀行為，並藉由群組訪談了解學生對系統中輔助理解功能的觀感。研究結果顯示本電子教科書系統對於幫助中、高學習成就群的學生理解教材內容有正面的效果。參加實驗的學生普遍認為本電子教科書系統具有便於理解、提高學習動機、提升閱讀速度等各項優點，同時也認為本系統適合於課後自行複習之用。The purpose of this study was to develop an electronic programming textbook system with comprehension-improving features. Our design took advantage of the dynamic nature of electronic media by highlighting the relationship between textual description and the target it describes, resulting in better congruence of text, graphical illustrations, and program code in the learning material. A modified randomized-groups pretest-posttest design was used to investigate the effect of the use of our electronic textbook system on learners’ comprehension of pointers in C programming. Reading behavior of students in the experimental group was also recorded on the observation sheet during the experiment. This was followed by a group interview to collect the participants’ opinions about the design features. Results revealed that our electronic textbook system was effective in facilitating comprehension for higher and medium achievement group of participants. In addition, students in the experimental group found the reading-aid features helpful in enhancing their understanding of the material, in motivating learning and enabling faster reading speed at the same time. They also suggested that our electronic textbook was appropriate for after-class reviews.
