Impact of Learning Outcomes of National Park Science Popularization and Education Volunteer Activity on Daily Pro-Environment Behavior: Mediating Role of Meaningfulness and Environmental Passion.

Volunteer activities based on national parks represent a crucial pathway for public participation in the construction of ecological civilization, as well as an important means for national parks to achieve public welfare goals. Hainan National Park science popularization and education volunteers were invited to participate in a questionnaire survey, yielding 437 valid responses. PLS-SEM was employed to test the conceptual model of "learning outcomes–meaningfulness/environmental passion–daily pro-environmental behavior". The findings indicate that learning outcomes (knowledge accumulation, skill cultivation, changes in environmental attitude, and self-reflection) positively influence both meaningfulness and environmental passion; meaningfulness positively influences environmental passion; and both meaningfulness and environmental passion positively affect daily pro-environmental behavior. Specifically, meaningfulness mediates the relationships between knowledge accumulation, changes in environmental attitude, self-reflection, and daily pro-environmental behavior, while environmental passion mediates the relationships between knowledge accumulation, skill cultivation, changes in environmental attitude, self-reflection, and daily pro-environmental behavior. This study clarifies the connotations and dimensions of learning outcomes from national park science popularization and education volunteer activities and enriches research on the mechanisms promoting pro-environmental behavior. Moreover, it provides valuable practical implications for national parks. [ABSTRACT FROM AUTHOR]
