台灣早期的幼教發展，於政府長時期疏於管理下，導致現今幼教界存在諸多糾結複雜的問題，這些客觀外在環境條件所產生的問題，直接衝擊幼教核心之一「教師」角色的生存空間。在高師資流動性特質之幼教場域中，那些資深專業工作者如何能夠在所處的社會情境脈動中，長時期持續朝向自我選擇之幼教職業道路推進，為本研究的核心關注。透過一位資深幼教工作經歷的園長之生命視窗—她的工作經驗世界，理解幼師職業生涯運轉歷程的樣貌；並從主體生命故事敘說之縱向歷史回顧中，理解其中透露的重要社會結構變遷訊息。 本研究採取質性研究方法中的傳記研究取向，以德國社會學者Fritz Schütze所發展之「敘述訪談法」(narrative interview)進行資料採集工作，訪談一位具有二十九年幼教工作經歷的幼兒園園長。訪談結果整理為敘述文本後，並參照Fritz Schütze所提出的理論建構分析方案，對文本進行結構描述以及概念抽象化分析的整體形塑，以回應欲探究的問題。 經過資料分析過程，逐漸釋出本研究主體—杏芬園長「不成長就會被淘汰」的生命信念意涵，文本透露出自我完成性在主體生命開展歷程中，為一種突破環境限制與期望朝向更好的動力，促使主體一再超越現實環境的限制，萌生其積極性意義。「不進則退」生命觀於時間流動中架構出主體的生活經驗世界，形成生命能量內塑與外推之上揚動力，於接受工作挑戰與追求成長歷程中蛻變。於是可以看出，環境或自我本身的未確定性，雖然帶來了限制，卻也充滿無限可能性。最後，研究者就文本解析之內容，提出「公私幼消長生態下幼師的生存處境」議題進行探討；並且參照Csikszentmihalyi創造力系統論觀點，建立一個類似的系統原型，從個人、學門及領域三個面向，闡釋研究主體長期安身立命於幼教職業工作中的可能因素。 / “Either growing or eliminating”— A description analysis of a kindergarten teacher’s life revolving Due to the lack of management by the government in Taiwan in early years, there are many problems that exist in the field of early childhood education. Those impact the survival of the key personnel, the teachers, in this field directly. In the social context of high turn over ratio of the teachers in this field, how senior teachers keep standing fast at the post and moving forward is the center concern of this research. By interviewing a senior teacher’s working experience, the researcher gets to know the different patterns of the career of a kindergarten teacher; further more, to comprehend the transition of the social structure from reviewing the history in which the story happened. This research adopts biographic study under the qualitative methodology, and collects the data with “narrative interview” developing by Fritz Schűtze, a Germany sociologist. After interviewing a kindergarten principal, Sin-feng, who has been working for twenty-nine years in the early childhood education field, researcher followed Schűtze’s theory construction and analysis to analyze and shape the structure description and abstract concepts. After the process of data analysis, “either growing or eliminating” shows up to be Principal Sin-feng’s belief. The text shows that in one’s life process, self-completion is a motivation that can break through constrains of environment and head to a better situation. Therefore, we can see that although the uncertainty of environment and oneself can be constrains, it can also bring the unlimited possibility. At the end, researcher raised the topic of “kindergarten teachers’ subsistence in the growth and decline of public and private kindergartens” for discussion. Researcher revised and constructed a similar system from the creativity systematic viewpoint raised by Csikszentmihalyi, to explain the possible reasons, from personal, subject, and field aspects, that make the research object stay in the same career for such a long time.
