論證（Argumentation）於科學教育中是相當重要的一環，透過不斷的與人溝通，培養學生的表達能力，學會站在不同的立場思考，藉以提升學生思考的能力。但隨著時間的不斷變遷，我們面對的問題越來越複雜，教師藉著一己之力引導全班學生變得相當困難，因此本篇論文使用自然語言處理（Natural Language Processing, NLP）技術引入線上合作論證系統，致力於開發友善的論證空間以及學習歷程分析的功能，期望能促進論證小組間溝通的意願以進行良性的討論，提升學生思考上的進步，培養解決問題的能力。CoArgu線上合作論證平台的設計主要涵蓋了論證輔助鷹架、論點分析、情緒分析等，協助學生進行線上合作論證活動，目的在於讓學生提出自己的看法，引導學生以合作、友善的方式進行想法上的交流。待系統建置完成後，本研究針對68位高中生，採用問卷調查法，進行學生對於CoArgu線上論證平台的整體知覺有用性、整體知覺易用性、整體使用意願以及鷹架功能及輔助工具知覺有用性之初步評估。研究結果發現，多數受測高中生對於CoArgu線上論證平台的整體知覺有用性、整體知覺易用性、整體使用意願以及鷹架功能及輔助工具知覺有用性皆給予正向的回饋。並期望未來研究者能夠透過本研究之系統評估及學生給予的使用建議與回饋，作為未來改善系統的參考。;Argumentation is a very important part of science education. Through continuous communication with others, students′ expressive skills are cultivated, and students learn to think from different perspectives, so as to enhance students′ thinking ability. However, as time goes on, the problems we face become more and more complex. It is quite difficult for teachers to guide the whole class by their own efforts. Therefore, this researcher uses natural language processing (NLP) technology to introduce an online collaborative system. The participants were 68 students from high schools. The results of the study showed that most of the student expressed positive feedbacks on perceived usefulness, perceived ease of use, intention to use the system. Moreover, they expressed positive perception towards the scaffolds and tools within this platform . Suggestions for the improvement of the system and future study were also discussed.
