本研究目的探討兒童對「轉惡為善」的觀感以及環境整潔的敏感度。研究問題有二： （一）學童是否認同「惡轉善」的現象？（二）學童是否產生環境保護的態度? 研究對象為163 位觀賞兒童音樂劇演出的花東國小學童，研究方法採用兒童音樂劇學習單、兒童口頭分享及現場觀察紀錄。研究資料分析結果有四：（一） 學童普遍對髒亂環境的厭惡；（二）學童認同「善」的程度大於認同「惡」的程度；（三）學童對「惡人」的嫌棄情感亦含悲憐惡人「缺愛」的痛苦；（四）學童願意相信「轉惡為善」的可能。故本研究建議：（一）兒童音樂劇的展演方式，順暢學童道德情感的投射，值得推廣；（二）兒童音樂劇的展演方式，能潛移默化學童對環境整潔的敏感度，未來可配套環境保護行動日誌，發展知行合一的行動學習。

The purpose of this study was to explore children's perceptions of changing evil for good and their sensitivity to clean environments. This study targets two research questions: (1) Do students identify with the change from evil to good? (2) Do students develop an attitude of environmental protection? The subjects were 163 children in east Taiwan, who watched the performance of a children's drama. The study was conducted through students' learning logs and oral sharing, as well as on-site observations. Four findings concluded the study: (1) children popularly hold disgusting views of filthy environments; (2) more children express favorable impressions with good than with evil; (3) children's resentments of evil also carry pitiful feelings about evil's suffering of wanting more love; (4) children believe the possibility of changing evil for good. The study presents two suggestions: 1) promote applying children's drama to ease children's reflections on moral affection; 2) add a daily action log of environmental protection along with children's drama presentations, in that children's sensitivity to clean environments can be practiced in action learning.
