本研究基於知識翻新理論設計「線上同步合作論證學習平台」(Synchronize Collaborative Argumentation Learning System，以下簡稱SCALS)，平台設計目的在於讓學生能夠透過此平台，完成小組論證，提出自身的想法與看法，持續改進與反思，進而提升學生的論證能力、反思思考能力、合作學習能力等。在完成平台開發後，本研究讓學生使用SCALS平台進行討論，並相互給予意見與回饋，研究者依據學生給予的意見與回饋，以評估SCALS，本研究採用調查研究法的問卷調查法，針對42名的高中學生進行問卷調查，評估學生對於SCALS的整體知覺有用性、整體知覺易用性、整體使用意願，以及鷹架功能與論證互動工具的知覺有用性。研究結果發現多數受測學生對於SCALS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與互動工具的知覺有用性皆給予正面的回饋，多數學生提及，SCALS平台提供之功能，具備有用性與易用性，亦願意使用系統進行論證活動，最後根據本研究的研究結果顯示，提出SCALS的建議與未來研究建議。;The main purpose of this study is to develop the "Synchronous Collaborative Argumentation Learning System"（SCALS）based on Knowledge Building Theory to. By using the SCALS platform, the students are expected to improve argumentation skills and to have the opportunity to continuously reflect on their collaborative argumentation activity. After completing the development of the SCALS, a total of 42 Taiwanese high school students participated in the platform evaluations of SCALS. A modified questionnaire was used for the platform evaluations in terms of the students’ perceived usefulness of the SCALS, overall perceived ease of use, and willingness to use the SCALS. The research results indicated that the students expressed positive and satisfying perception regarding the usefulness and ease of use regarding the SCALS. Also, they expressed high willingness of using the SCALS for synchronous collaborative argumentation. Besides, they also indicated that the functions provided by SCALS were useful and user-friendly. Finally, from this research results of the data analysis, this study proposed suggestions and future research work for the improvement on SCALS.
