隨著社群媒體的熱潮持續延燒，許多科學新聞機構也開始透過臉書的粉絲專頁來發佈自己的新聞以增加新聞曝光率。過去有關於媒體粉絲專頁的研究多探討行銷行為，鮮少針對新聞機構的臉書專頁做研究，對於粉絲專頁社群編輯的引言所形成的框架效果研究也付之闕如。本研究包含兩個實驗法，將兩則不同主題的科學新聞（基因改造、奈米科技）各自配上三種不同框架的臉書引言-技術性框架、爭議性框架、和人情趣味框架，來探討臉書的引言對於科學新聞閱聽眾的影響。 結果發現，人情趣味的臉書引言只會增進讀者想要點擊新聞全文的慾望，卻不會對新聞主文的詮釋造成影響。爭議性臉書引言除了增進讀者閱讀新聞全文的慾望之外，也會再強化讀者對新聞全文的認知。然而這兩種框架對於讀者的新聞注意度、理解度和議題相關性沒有影響。 / As social media continue to gain popularity, scientific news agencies also adopt the trend to increase online presence and fuel exposure because of the growing need to strengthen the communication between scientists and the general public. This study investigated the potential power of the current most popular social media- Facebook in fostering public understanding of science by employing two one-factor between-subject web-based experimental factorial designs. Experiment 1 used genetic modification news and experiment 2 used nanotechnology news. Each piece of science news had three different Facebook framed leads: technique, conflict and human interest. Research results found human interest frame only served to arouse reader’s situational interest to click on the news feed to access to the full story but didn’t affect how readers interpret the main theme of the science news articles. On the other hand, conflict frame not only enhanced reader’s intention to click on the news feed but also reinforced how they perceive the main theme of the news story. However, the two soft news frames have no effect on reader’s perceived news attention, understanding and relevance. This study aimed to contribute to the literature as one of the first studies on the use of the social media in the realm of the public understanding of science.
