摘要 討論對於學習者是一個萌生對議題想法必經的過程，透過討論可提升對於議題的瞭解，過程中可針對資訊進行篩選、消化以及吸收，有效的討論有助於提升學習成效。為求即時與便利，透過網路討論已是無可避免的趨勢。因此，本研究設計「語義分析網路即時回饋系統（Semantic Network Instant Feedback System，簡稱SNIFS）」，希望透過呈現學習者討論內容中的詞彙語意網絡，輔助學習者掌握問題討論方向，進而有效提升網路學習成效。

本研究採用準實驗研究，隨機選取台北市某高中二年級兩班共64名學生為研究對象，進行「核能發電與燃煤發電選擇」主題之線上討論。其中採用「SNIFS輔助討論區」輔以線上討論的實驗組學生32名，僅採用一般傳統線上討論區輔以線上討論的控制組學生32名，探討兩組學習者在學習成效與科技接受度上是否具有顯著差異。此外，也以先備知識、電腦中介溝通（Computer-Mediated Communication， 簡稱CMC）能力以及認知風格作為背景變項，探討兩組具三種不同背景變項的學習者，在學習成效及科技接受度上是否具有顯著差異。

研究結果發現，相較於使用一般傳統線上討論區，採用「SNIFS輔助討論區」對於低先備知識以及高CMC能力學習者的學習成效具有顯著的助益。SNIFS能夠幫助低先備知識的學習者產生更多的觀點，也能夠幫助高CMC能力學習者提高討論的複雜度，使其對討論議題有更深入地認識。而在科技接受度上，實驗組與控制組的分數普遍偏低，顯示兩組學習者對於系統的科技接受度都不算高。在兩組科技接受度皆不高的情況下，整體控制組學習者或是文字型學習者在科技接受度及認知易用性上顯著優於實驗組。此外，本研究之質性資料分析顯示，造成控制組學習者科技接受度優於實驗組的可能原因，為學習者認為本研究所採用之討論區不完全符合需求，而實驗組除了討論區外，還需要使用SNIFS，因此增添了系統的複雜性，進而影響到實驗組學習者使用SNIFS系統進行討論的流暢度。

最後基於研究結果，本研究提出SNIFS以及一般線上討論區設計上的改進建議，以及未來可以繼續發展的研究方向。整體而言，本研究發展的SNIFS系統有助於發展出結合線上討論區及討論詞彙語意視覺化之創新線上討論工具，對於促進網路學習之線上討論成效具有貢獻。
Discussion is the process for a learner coming up with ideas about an issue. Discussion could enhance the understanding of issues and selecting, digesting, and absorbing information in the process. Effective discussion could enhance learning effectiveness. For the immediacy and convenience, online discussion has become an inevitable trend. The “Semantic Network Instant Feedback System (SNIFS)” is therefore designed in this study, expecting to present the semantic network of words used in learners’ discussion contents, assist learners in grasping the question discussion direction, and further effectively enhance online learning effectiveness.

With quasi-experimental research, a total of 64 Grade 11 students from two classes of a senior high school in Taipei City are randomly selected as the research subjects for the online discussion of “options of nuclear power generation and coal-fired power generation”. “SNIFS assisted discussion” is applied to 32 students in the experimental group, and general online discussion is used for another 32 students in the control group. The learning effectiveness and technology acceptance of the learners in two groups are discussed the differences. Furthermore, prior knowledge, computer-mediated communication (CMC) ability, and cognitive styles are used as the background variables to discuss the effects on learning effectiveness and technology acceptance.

The research results discover that “SNIFS assisted discussion”, compared to general online discussion, shows significant benefits on the learning effectiveness of learners with low prior knowledge and high CMC ability. SNIFS could help learners with low prior knowledge generate more points of view as well as assist those with high CMC ability in enhancing the discussion complexity to have deeper understanding of the discussed issue. In terms of technology acceptance, both the experimental group and the control group present lower scores, revealing low technology acceptance of learners in both groups. In this case, learners in the control group or verbalizers remarkably outperform those in the experiment group on technology acceptance and perceived ease of use. Furthermore, the qualitative data analysis in this study reveals that learners in the control group outperforming those in the experimental group on technology acceptance possibly because learners consider the applied discussion not completely conforming to the demands. The experimental group, on the other hand, has to use SNIFS beyond discussion that increases the system complexity and further affects the fluency in the discussion with the SNIFS system.

Based on the research result, suggestions for improving the design of SNIFS and general online discussion and future research directions are proposed in this study. Overall speaking, the SNIFS system developed in this study could help develop the innovative online discussion tool combining online discussion and semantic visualization of discussed words to contribute to the online discussion learning effectiveness.

dc.description.abstract (摘要) 討論對於學習者是一個萌生對議題想法必經的過程，透過討論可提升對於議題的瞭解，過程中可針對資訊進行篩選、消化以及吸收，有效的討論有助於提升學習成效。為求即時與便利，透過網路討論已是無可避免的趨勢。因此，本研究設計「語義分析網路即時回饋系統（Semantic Network Instant Feedback System，簡稱SNIFS）」，希望透過呈現學習者討論內容中的詞彙語意網絡，輔助學習者掌握問題討論方向，進而有效提升網路學習成效。

本研究採用準實驗研究，隨機選取台北市某高中二年級兩班共64名學生為研究對象，進行「核能發電與燃煤發電選擇」主題之線上討論。其中採用「SNIFS輔助討論區」輔以線上討論的實驗組學生32名，僅採用一般傳統線上討論區輔以線上討論的控制組學生32名，探討兩組學習者在學習成效與科技接受度上是否具有顯著差異。此外，也以先備知識、電腦中介溝通（Computer-Mediated Communication， 簡稱CMC）能力以及認知風格作為背景變項，探討兩組具三種不同背景變項的學習者，在學習成效及科技接受度上是否具有顯著差異。

研究結果發現，相較於使用一般傳統線上討論區，採用「SNIFS輔助討論區」對於低先備知識以及高CMC能力學習者的學習成效具有顯著的助益。SNIFS能夠幫助低先備知識的學習者產生更多的觀點，也能夠幫助高CMC能力學習者提高討論的複雜度，使其對討論議題有更深入地認識。而在科技接受度上，實驗組與控制組的分數普遍偏低，顯示兩組學習者對於系統的科技接受度都不算高。在兩組科技接受度皆不高的情況下，整體控制組學習者或是文字型學習者在科技接受度及認知易用性上顯著優於實驗組。此外，本研究之質性資料分析顯示，造成控制組學習者科技接受度優於實驗組的可能原因，為學習者認為本研究所採用之討論區不完全符合需求，而實驗組除了討論區外，還需要使用SNIFS，因此增添了系統的複雜性，進而影響到實驗組學習者使用SNIFS系統進行討論的流暢度。

最後基於研究結果，本研究提出SNIFS以及一般線上討論區設計上的改進建議，以及未來可以繼續發展的研究方向。整體而言，本研究發展的SNIFS系統有助於發展出結合線上討論區及討論詞彙語意視覺化之創新線上討論工具，對於促進網路學習之線上討論成效具有貢獻。		zh_TW
dc.description.abstract (摘要) Discussion is the process for a learner coming up with ideas about an issue. Discussion could enhance the understanding of issues and selecting, digesting, and absorbing information in the process. Effective discussion could enhance learning effectiveness. For the immediacy and convenience, online discussion has become an inevitable trend. The “Semantic Network Instant Feedback System (SNIFS)” is therefore designed in this study, expecting to present the semantic network of words used in learners’ discussion contents, assist learners in grasping the question discussion direction, and further effectively enhance online learning effectiveness.

With quasi-experimental research, a total of 64 Grade 11 students from two classes of a senior high school in Taipei City are randomly selected as the research subjects for the online discussion of “options of nuclear power generation and coal-fired power generation”. “SNIFS assisted discussion” is applied to 32 students in the experimental group, and general online discussion is used for another 32 students in the control group. The learning effectiveness and technology acceptance of the learners in two groups are discussed the differences. Furthermore, prior knowledge, computer-mediated communication (CMC) ability, and cognitive styles are used as the background variables to discuss the effects on learning effectiveness and technology acceptance.

The research results discover that “SNIFS assisted discussion”, compared to general online discussion, shows significant benefits on the learning effectiveness of learners with low prior knowledge and high CMC ability. SNIFS could help learners with low prior knowledge generate more points of view as well as assist those with high CMC ability in enhancing the discussion complexity to have deeper understanding of the discussed issue. In terms of technology acceptance, both the experimental group and the control group present lower scores, revealing low technology acceptance of learners in both groups. In this case, learners in the control group or verbalizers remarkably outperform those in the experiment group on technology acceptance and perceived ease of use. Furthermore, the qualitative data analysis in this study reveals that learners in the control group outperforming those in the experimental group on technology acceptance possibly because learners consider the applied discussion not completely conforming to the demands. The experimental group, on the other hand, has to use SNIFS beyond discussion that increases the system complexity and further affects the fluency in the discussion with the SNIFS system.

Based on the research result, suggestions for improving the design of SNIFS and general online discussion and future research directions are proposed in this study. Overall speaking, the SNIFS system developed in this study could help develop the innovative online discussion tool combining online discussion and semantic visualization of discussed words to contribute to the online discussion learning effectiveness.		en_US
