| Summary: | Purpose: The goal of this study is to develop and apply learning modules to help community dental hygienists acquire the necessary competencies and verify the effectiveness of the modules.Methods: On the basis of 12 domestic and international reference papers, the concept of a community dental hygiene process of care was defined, and 393 learning goals were found to perform the primary and secondary categorization processes. The final 52 learning goals were assigned as a 15-week module series to develop project-based learning modules. The modules were used in 2018 during the first semester of the community dental hygiene practicum at G University (bachelor's degree) and H University (associate's degree). Surveys were performed before and after the application of the modules to evaluate the method's effectiveness.Results: Confidence in problem-solving abilities, project value, teamwork competency, and community dental hygiene competency were compared before and after the application of the modules. Students at both G and H universities showed statistically significant improvements across all 4 indices. Project authenticity and learning outcomes were analyzed in students at G and H universities after applying the modules; the results demonstrated that project authenticity and learning outcomes were positive.Conclusion: The learning modules can be presented as systematic educational modules, which have inherent academic significance for dental hygiene, and in turn can strengthen students' competency in community practice areas.
