| 摘要: | 本研究的主要目的在於探討課程論壇中，學生討論內容的知識建構層次和行為模式。我們以中央大學計算機概論課程論壇為研究對象，對論壇中學生的討論內容進行分析。首先，根據互動分析模型(Interaction Analysis Model ,IAM)的知識建構階層，對論壇中學生發表的留言進行編碼分類；接著，將編碼完的結果分別利用定量內容分析(quantitative content analysis)和滯後序列分析(lag-sequential analysis)，說明產生的結果。本研究結果顯示以不同的編碼單位對討論內容進行編碼，結果大致上是一致的，所以若將研究結果與其他相同性質的結果比較，就算研究使用不同的編碼單位，並不會造成研究間比較結果的變因。將本研究的結果跟先前一些同質性的研究結果做對照，結果大致相仿，學生們討論的知識建構層次，大部份集中於K1層次，主要內容為分享、比較資訊或提出相同的看法。 本研究的另一個目的在於探討老師適時的介入學生的討論，是否可以提升學生討論過程中的知識建構層次，以增加學生的學習成效。侯惠澤(2007)發表的文章中，建議老師主動提供學生討論的方針與回饋，以提升學生討論過程中的知識建構層次。本研究的結果顯示，有老師適時地介入學生的討論，適時地給予學生討論方向，或引導學生進入更深更廣的討論，可以促進學生較高知識建構層次(K3、K5)的討論，可有效地提高學生的學習成效。 此外，研究者發現以往觀察線上非同步討論平台的研究，幾乎都是針對特定某一族群於特定某一短時間內的討論內容進行分析，而這般特定族群的結果是否能夠代表整體的表現？群體間特性的差異是否會造成不同的結果？本研究結果顯示，不同的學生族群進行討論的模式不盡相同，所以於短時間內某一群學生的討論行為，不足以代表整體學生討論的行為表現。 最後，根據以上結果，本研究針對要以課程論壇讓學生進行討論的老師，以及往後要研究線上非同步討論平台的研究者提出一些具體的建議。The main purpose of this study is to explore the level of knowledge construction and behavior of students’ discussion in the course forum. We analyzed the content of students’ discussions in the course forum of Introduction to Computer Science course of National Central University. According to the classifications of knowledge- construction, Interaction Analysis Model (IAM), coding the post messages of students in the course forum. We illustrate the results with quantitative content analysis and lag-sequential analysis. The results of this study would be encoded and counted in different units, articles and paragraphs. Then we got that using different coding units encode the contents of students’ discussion, the results generally are consistent. In view of this, put the results of similar studies together, even if studies using different coding units, it would not cause any changes in the comparison between studies.Comparing the results of our study with findings of some previous similarly studies, the results shows that, the knowledge-construction of students’ discussions are concentrated in K1 level - the main contents are sharing, comparing of information or raised the same views.Another purpose of this study is to explore that if teachers involve in the discussions timely, would it enhance the level of knowledge-construction or no in order to increase students’ learning during the discussion. Hou (2007) found that if teachers did not involve in the discussion, the knowledge-construction are mostly in the lower levels, K1and K2. He recommends that teachers actively provide guidance and feedback to students, to enhance the level of knowledge-construction during the discussions. The results of this study showed that teachers involved in students’ discussions timely, and gave students the direction of discussions timely or guided students into deeper and broader discussions, it could promote a higher level of knowledge-construction (K3, K5) of discussions between students, and may improve students’ learning effectively.Besides, we found that the previous research of observing discussions in online asynchronous platforms; almost all analyses are focused on the content of specific group in a particular short time. We want to know whether the results of such a particular group can represent the overall performance or no, and if the difference between groups will cause different outcomes or no. We recount the data of each academic year separately, and it showed that there are different behavior patterns between the discussions of different groups in the short term. So we got that the behavior of a group of particular students’ discussions in the short term could not represent the behavior of overall students. Finally, according to the above results, this study proposes concrete suggestions to the teacher who allow students to discuss in a course forum and to the researchers study asynchronous online discussion platform in the future. |
