本研究旨在探究問題本位學習模式是否能有效提高學生減塑行為的認知與態度。另外也想瞭解性別、同儕影響、具體環境知識、獲得環境資訊的媒介、在地環境參與度、父母的影響、環保意識等因子對學生減塑行為認知與態度決策改變之影響。本研究採準實驗研究設計,實驗組58人(兩組不同的實驗介入)及控制組28人,共計85人。研究結果發現:(1)本課程能有效提高學生的認知和態度;(2)同儕影響、具體環境知識、獲得環境資訊的媒介為影響學生減塑行為認知表現的重要因子;(3)性別為影響學生減塑行為態度的重要因子;(4)在地環境參與度、父母的影響、環保意識對認知和態度皆無影響。依研究結果及對未來的研究提出多項研究建議。
This study explored whether the environmental protection curriculum designed with PBL could effectively improve students' awareness and attitudes of plastic reduction behavior. The researcher investigate into whether gender, peer influence, specific environmental knowledge, media exposure to environmental information, participation in local environmental activities, and environmental awareness were essential factors affecting students' cognition of plastic reduction behavior and decision-making attitude. In this study, the researchers applied quasi-experimental design and cluster sampling. A total of 85 people participated, with 58 people in the experimental group (divided into two groups due to different experimental interventions) and 28 people in the control group. The results are as follows: (1) This course can effectively improve students' cognition and attitude; (2) Peer influence, specific environmental knowledge, and media exposure to environmental information are important factors that affect students' cognitive performance in plastic reduction behavior; (3) Gender is an important influencing factor on students' attitudes towards plastic reduction behavior; (4) Participation in local environmental activities, parental influence, and environmental awareness have no effect on cognition and attitude. The results provided valuable pedagogical suggestions for future research.
