Immersive Ocean Education in a Public Science Hall: A Holographic Interaction-Based Study on Children's Pro-Environmental Behavior

Plastic pollution is gradually becoming one of the most urgent threats to marine ecosystems, and traditional education methods often difficult to promote people's awareness of environmental protection into practical actions. In this regard, we try to explore a more immersive and interactive educational method to help children understand the importance of marine protection more deeply. In this study, a teaching mode named “Interactive Multi-sensory Space (IMS)” is introduced, and the real marine environment is simulated by holographic projection technology to create an immersive learning experience. Based on the “Fogg Behavior Model (FBM)”, we design an IMS system that integrates gamification tasks and instant feedback. In the holographic projection exhibition hall of a garbage incineration plant in Zhuhai, China, we invited 30 primary school students aged 9 to 11 to participate in the experience and evaluated their changes in motivation, understanding and behavior through on-site observation, student interviews and family visits. From the results, children generally show stronger emotional input, have a deeper understanding of marine pollution problems, and show positive environmental protection behavior both inside and outside the classroom. For example, some students take the initiative to discuss the use of plastics with their families, and some children are willing to share their learning experiences on social media. These findings show that when immersion technology is reasonably designed and combined with the principles of behavioral science, it can not only transfer knowledge but also stimulate real action. This educational model provides a new idea for future sustainable development education and shows a practical path that can be popularized and full of potential so that more young people have the opportunity to become guardians of the ocean.
