Abstract: Developing curiosity in elementary school students requires learning resources that encourage active participation and exploration during learning activities. However, teaching materials that integrate curiosity development with sea transportation civilization through project-based learning remain limited. This study aimed to develop a Project-Based Learning (PjBL)-based textbook on sea transportation civilization to foster curiosity among elementary school students. The study employed a Research and Development (R&D) method using the ADDIE model. Product effectiveness was examined through a quasi-experimental pretest-posttest non-equivalent control group design involving 52 fourth-grade students, consisting of 26 students in the experimental group and 26 in the control group. Data were analyzed using Analysis of Covariance (ANCOVA) and Krippendorff's Alpha to examine inter-rater reliability. The findings showed that the textbook achieved a very good validity category and required no revision. The ANCOVA results revealed a significant difference in curiosity between the experimental and control groups after accounting for students' initial abilities. The reliability analysis indicated an adequate level of agreement among raters. These findings suggest that the PjBL-based textbook can serve as an alternative learning resource to foster curiosity through project activities and exploration of sea transportation civilization in elementary school.
