本研究以社會網絡分析，調查93位大學生在一線上課程之學期初、學期末的實體互動網絡、以及學期中在線上的互動網絡，並嘗試歸納與描繪出：在校園線上學習脈絡下，線上與線下世界的不同樣態，以及兩個世界如何彼此發生交錯的整體圖像描述。研究結果顯示：在校園線上學習場域之脈絡中，線上世界的「弱聯繫、打破原實體社會邊界、中心主流與邊陲多元並存」經驗，對實體網絡產生了一定的改變與影響，包括：弱聯繫之替代效果；虛擬世界邊陲的失落，引發實體小群體強聯繫之補償效果；虛擬意見領袖之弱移轉效果。

Using social network analysis, this paper explored three 93*93 social networks and their relationships: an online network within a school term, two offline networks both before and after the term. We try to describe the holistic social configuration in the on-line and off-line world of campus e-learning, and explore the difference and influence between on-line and off-line worlds. Results show that: in the context of campus-kind of on-line learning, the structural features of on-line network, which is most different to offline network, including: weak ties, breakthrough the offline social boundary, and “mainstream-centered ＆ diversified border groups” configuration. Those structural features had significantly changed some aspects of the offline network, including: the supplement effect of offline weak information ties, compensating the online mainstream-centered dominance by intensify the offline cliques with stronger within group intimacy and interaction, and the weak transfer from online opinion leader to offline one.
