<p>過往在婦幼傳播裡,醫療專家論述往往指導其中,建構母職典範;今日,隨著社會變遷與知識普及,母職實踐已多所變化,社群媒體與平台更讓這種情況蓬勃開展,但也帶來風險與挑戰。本文以兩個婦幼官網討論區資料進行文本分析,提煉共能知識(co-empowermental knowledge)。研究發現有三:(一)在閱聽人研究上,媽媽閱聽人以社群網路共構的母體知識,實踐主體意識共同覺醒,以及科學知識相互賦能等多重意義;(二)在媒體傳播演變裡,她們的知識來源與主體性再轉移,從口耳相傳到媒體中介,反映出臺灣母職非正式支持系統的演變;(三)在醫用關係中,新世紀女性可以在更自由的環境中使用知識、參與消費、實踐自我,然而也需要新時代的各類專家協助,共能知識將開展新一波的「醫」用協商。</p> <p>&nbsp;</p><p>Within the discourse of motherhood, medical expertise often played a dominant role, possessing the power to construct the image of ideal motherhood. However, the rise of social media altered the way people receive information and complicated the relations between expert opinions and actual mothering practice. This paper employs text analysis to examine the &ldquo;co-empowermental knowledge&rdquo; shared by the users of two online mothering forums. The major findings are as follows: first, in terms of audience studies, the mothers in the forums are practicing collective consciousness awakening and mutual empowerment by using knowledge they have co-constructed on social media. Second, along with the evolution of media, the sources of knowledge of the mothers and their subjectivity have shifted again and again, from oral tradition to media-based knowledge. This shift also illustrated the evolutionary path of informal support systems for mothers in Taiwan. Third, in terms of professional-user relationship, women in the new era enjoy more freedom to apply knowledge, to participate in consumption, and to pursue self-realization. At the same time, they also need help from the experts of the new era. The co-empowermental knowledge will begin a new wave of professional-user negotiation.</p> <p>&nbsp;</p>
