The effect of project-based learning modules on a community dental hygiene practicum in South Korea.

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.
