從民族誌取向評量Petrosains科學中心「科學童軍」長期方案的影響

An Ethnographic Approach to Measuring the Impact of the Petrosains Science Scouts, a Long-Term Science Centre Program

你知道你的長期教育方案有何影響嗎？科學中心的評量常常調查可測量的成果，調查方式通常是在活動後進行取樣調查。然而，對於執行多年的長期方案之影響，如何瞭解呢？本文分享對於至今已邁入第5年的Petrosains科學童軍計畫影響的研究發現，該計畫是為7歲至17歲學童所舉辦的長期課後活動。本研究採用民族誌方法論，在參與者家中透過非結構觀察、非正式訪談、攝影與社交活動進行資料收集。研究進行流程包括「探索」階段（瞭解參與者的基本與背景資料）、「定義」階段（瞭解參與者對科學與科技的興趣）、「確認」階段（瞭解參與科學童軍計畫是否增進參與者對於科學、技術、工程、數學的覺知，以及對於參與者學習行為的影響）。本研究結合民族誌研究的質性資料與家長調查、訪談的量化資料，提出具有洞見與可永續運用來評量長期影響的模式，並且，本研究評量過程展現的主要機制，亦有助於其他科學中心規劃長期方案影響評量之參考。

Do you know the impact of your long-term programs? Evaluation in science centres often investigate measurable outcomes, usually sampled immediately after the experience, but what about the impact of programs conducted over years? This study shares the findings of an investigation into the Petrosains Science Scouts, a long-term after school program for children from ages 7 to 17 which is currently in its 5th year. The study adopts an ethnographic methodology with data collection done through unstructured observations, informal interviews, photographs, and socializing, all at the respondent's own home. The flow of data comprises of the ‘Explore’stage (to study respondents' profile and background), the ‘Define’ stage (to establish respondents' interest in science and technology) and the ‘Confirm’ stage (to determine whether program participation has shaped respondents' perception of STEM and the influence on their learning behaviours). The qualitative data from the ethnography study is combined with quantitative data from parent surveys and interviews to come up with an insightful and sustainable model for measuring long-term impact. This study will also present the broad mechanics of this evaluation process which will be useful for other Science Centres who are planning to evaluate their long-term programs.
