近年來，由於寫作教學實施的成效不彰，造成國小學生寫作能力普遍低落。因此，徹 底落實寫作教學理論，並融入相關資訊科技作爲輔助，已是刻不容緩之事。有鑑於此，本 研究首先分析並統整國內外有關寫作教學、網路與寫作之相關理論。接著，本研究將介紹 「網路寫作系統」的發展目的與理念。此系統的功能主要是依據上述分析之寫作理論而設 計，其目的在於利用網際網路提供學生一個公開發表文章與同儕相互回饋的環境。本研究 以質性與個案研究的方式，探討此系統在一個國小六年級的班級中實施狀況。主要的研究 結果如下： 1. 教師認爲實施網路寫作可提供學生發表、觀摩文章與相互回饋的環境，但在執行上發 現學生較缺乏網路著作權與網路倫理的觀念。另外，提出增設榮譽榜機制以激勵學生 學習的建議。 2. 在網路寫作系統中，這班級的同儕間書寫互動可歸納成「文章段落格式」、「文字修 改」、「標點符號」與「文章內容」等類別。其中以文章內容的回應意見次數最多。 3. 三位焦點學生均喜愛以網路寫作的方式寫文章。此外，三位焦點學生之作品呈現不同 風格。寫作程度較成熟的學生，其作品偏向傳統正規的寫作形式。而寫作程度較不成 熟者，其作品中呈現非正式、口語化的寫作形式。 最後，依據研究結論，提出教學及後續研究的建議，以供參考。

In recent years, due to the ineffectiveness of writing instruction, most elementary school students are not able to achieve a satisfactory level of writing skills. Therefore, there is an emergent need to implement the writing instruction based on some well-developed theories and strategies, and to assist the process of writing with some technology tools. As a result, this study first analyses and summarizes some of the current theories of writing and summarizes. Then, the theoretical underpinnings and practice of a “ web-based system for writing” will be described. This system is designed and developed based on the theories of writing and writing instruction. The purpose of this system is to provide an on-line writing environment for students to present their compositions publicly and receive feedback from their peers. The study discussed the current implementation of this system by qualitative research methods. The findings from the research were as follows : 1. The teacher and students made suggestions about interfaces and functions.The teacher considered this system could provide an on-line writing environment for students to present their compositions and receive feedback from their peers. But student have no conception of the copyright conception. In addition to a points - accumulating system to encourage students' motivation. 2. The peers of writing interactions could be inducted some categories, such as “paragraph format , words-revised , punctuation marks and paragraph content . 3. Three students like writing by the web-based system. Besides, their works presented different styles. The more mature writer of modes writing was traditional and standard. The more mature writer of modes writing was informal and colloquialism. Finally, based on the finding, the researcher presents pedagogical implications and topics for further research in the future.
