從民族誌取向評量Petrosains科學中心「科學童軍」長期方案的影響

Abstract

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.
