SDGs12「責任消費與生產」旨在確保永續的消費與生產模式，因此這堂課Ian老師帶著大家透過專題報告的方式，探討各種循環經濟的實際案例，了解現行中小企業對地球永續的貢獻。

在報告過程中，老師發現同學們的演說技巧有明顯的進步，也懂得增加與觀眾的互動，讓報告內容更加生動吸睛。報告結束，老師也讓大家進行同儕互評，學習彼此的優點，更深入討論報告的主題內容。

In this unit, the teacher, Ian, guided students in learning about SDGs 12: Responsible Consumption and Production. This Grade 11 project focused on recycling, upcycling, and downcycling as part of the circular economy. Students investigated real-life examples from companies and explored ways to reduce waste by reusing and repurposing materials.

Through presentations, students improved their speaking and interaction skills by asking questions to engage the audience, while the audience provided helpful feedback to their peers.

After the presentations, students wrote argumentative essays to practice critical thinking and organizing their ideas clearly. The goal was to inspire students to notice their surroundings and start using sustainable practices in their daily lives.
