In addition, this study also examined the change and factors of change in aspects of the participant’s affinity for nature that directly relate to marine and coastal resources and environments.

Comparisons of overall mean scores were used to determine if affinity for nature changed due to participation in the environment education program. Analysis of variance was used to determine which participant characteristic and experiential variables had a significant influence on affinity for nature index scores. Findings indicated that participation in environmental education experience had a positive change on affinity for nature scores. Residence, ethnicity/language, and gender were also found to significantly influence sense of community various affinity for nature index scores.
