本研究主要目的在探究知識翻新活動對小學生節能減碳概念理解的影響。以知識翻新理論 (knowledge building) 作為教學核心理念，並以知識論壇(Knowledge Forum，KF)─電腦支援協作學習工具─來輔助與紀錄學生的學習。研究方法採個案研究法，研究對象為台北市某國民小學五年級某班學生(N=34)，研究時程為一學年，課程以節能減碳為主題。資料來源包括：(1) 知識論壇上之想法討論與互動歷程；(2)知識論壇平台之溫室效應與節能減碳想法貼文；(3)節能減碳概念理解之測驗。資料分析包括：(1)以知識論壇的分析工具(Analytic Toolkit, 簡稱ATK)分析學生在平台上想法討論與互動的行為；(2)分析學生在平台上所發表的貼文內容之階段性發展，並將學生所討論的概念與環保署所提供的溫室效應與節能減碳國中教材進行比較，以檢測學生所提的概念之完整性與豐富度；(3)使用創造力概念的流暢性、變通性、獨創性、精密性等四個面向，檢驗學生共構的知識品質；(4)分析課程結束後所進行的節能減碳概念測驗，檢測學生在知識翻新活動下對節能減碳概念的理解。研究結果發現：(1)知識翻新教學有助於促進以「想法」為單位的學習與互動模式；(2)知識翻新的學習環境有助於學生共創豐富的知識；(3)在知識翻新的學習環境中，呈現學生的想法數量漸趨減少但品質漸趨提升的情況；(4)讓學生自己翻新知識以主動學習，相較於被動的學習方式，更有助於提升學生在科學學習上的成效。根據上述結論，本研究提出下列幾點建議：（1）教師應重視學生的想法；(2)教師應鼓勵以想法為中心的互動與學習；（3）教師應幫助學生發展創新知識的關鍵能力；(4) 教育相關單位在設計課程與測驗時，更應重視學生的深層理解；(5)教師在教學上應善加利用網路學習資源。 / The purpose of this research was to investigate the effects of knowledge building activities on elementary students’ concepts of energy saving and carbon reduction. Knowledge building pedagogy and Knowledge Forum (KF)─an computer-supported collaborative learning environment─was employed in this study to document the process of students’ idea generation and development. This study employed a case-study design. Participants were a class of fifth graders from an elementary school in Taipei (N=34). They participated in a natural science class for a year and the topic of inquiry was about energy saving and carbon reduction. Data sources included: (1) Students’ online discussion recorded in a KF database; (2) Student’s ideas about energy saving and carbon reduction; (3) Students’ final test about energy saving and carbon reduction. Data analysis include: (1) descriptive analysis using Analytic Toolkit (ATK) and Social Network Analysis to document students’ interactive processes online; (2) qualitative analysis on the content of notes posted in KF; (3) content analysis, using the four aspects of creativitiy--fluency, flexibility, originality, and elaboration--to examine the quality of ideas generated by students; (4) learning assessment using the final comprehension test to evaluate students’ level of understanding about energy saving and carbon reduction in knowledge building environment. The main findings were as follows: (1) Knowledge building instruction was found helpful for supporting students’ work with “ideas”; (2) Knowledge building environment was conducive to knowledge advancement; (3) In the process of knowledge building, it showed the number of ideas was decreasing but the quality of ideas was improved; (4) Knowledge building environment was helpful for students to enhance science learning. Building on the findings, this study made the following suggestions: (1) Teachers should value students’ ideas; (2) Teachers should encourage students to interact and work with ideas; (3) Teachers should help students develop capacity for creating new knowledge; (4) When designing instruction, it is essential to emphasize deeper understanding; (5) Teachers should make good use of the online learning resources.
