ABSTRACT This study aims to assess the impact of the Coastal Marine Science Fieldwork (CMSF) Program in enhancing students' systematic thinking. To prepare students for their role as future global citizens, it is essential to expose them to socioscientific issues and provide first-hand experiences that reveal the interconnectedness of Earth's systems and human activities. Our research yielded the following insights: (1) Students demonstrated a significant increase in systems thinking, environmental nature of science views, and citizen science literacy after the CMSF program, (2) The program afforded students the opportunity to immerse in scientific investigations in ecological environments, effectively bridging the gap between textbook knowledge and the natural world, and (3) Fieldwork opportunities empowered students to assess their compatibility with scientific research, aiding them in making informed career choices in the field of science. This study holds educational significance for students pursuing majors in marine science or related fields at the higher education level. The integration of fieldwork into the learning process allows students to fortify their perspectives on the nature of science, ultimately promoting a greater number of students to consider science as a profession or actively participate in civic action.
