以小組與時間分析網路專題導向學習社群線上討論之實證研究

An Empirical Study of Analyzing Online Discussions in Web-Enabled Project-Based Learning Community based on Team and Time

本研究目的旨在以小組與時間為基礎，探討網路專題導向學習期間各小組每週線上討論分享次數表現的變化趨勢。本研究以師資培育中心修習教學媒體課程的15位學生為對象，進行為期七週的網路專題導向學習之個案實證研究。資料蒐集方式為利用網路學習紀錄蒐集登入系統次數、討論次數等資料。研究結果顯示，每週平均及各小組每週平均的登入系統、公共討論、專題討論、專家討論、及線上討論總次數在七週專題學習過程中的變化曲線，皆呈現先上揚再下滑的趨勢，以中間時段的參與最為踴躍，開始與結束時段則較不熱烈。
