This article presents a synopsis of an interdisciplinary asynchronous online science service-learning course for upper undergraduates and graduate students. The design process, structure of the course, pedagogical approaches, and specific goals are described. Discussions, analyses, and evaluations from both students and university faculty highlight the experience and lessons learned from the process. Our study shows that our approach impacted students positively, including developing a more positive attitude toward biodiversity protection and some behavioral changes in their personal life as well as their professional life.
