Abstract
3R education for high school students is one of the effective measures to cope with the increasingly severe plastic waste pollution in Vietnam today. Research results show that students in high schools in the Central region have a relatively high awareness of plastic waste. However, their knowledge, behavior, and level of access to education about plastic waste are still limited. From there, the article analyzes the ability of 3R education to reduce plastic waste for students through experiential activities in high schools, demonstrated through educational content, design process, organization, and implementation method. The research results can be a reference for high schools to conduct educational activities to reduce plastic waste and build “green, clean, beautiful schools”.
