Problem-based learning and the workplace: do dental hygienists in Hong Kong continue to use the skills acquired in their studies?

Problem-based learning (PBL) has been implemented in the dental hygiene program at the University of Hong Kong since 2001, but research is lacking to address the level of retention in the workplace. The purpose of this study was to explore whether dental hygienists continue to use their PBL skills and how well those skills are being applied in the workplace. A total of eighteen dental hygienists from the 2006 program were invited to participate in this study. A survey was conducted and follow-up group interviews carried out in 2008. The results revealed that dental hygienists continue to use the PBL skills of communication with the patient, patient education, and independent learning, but seldom use dental knowledge, teamwork, and communication with colleagues. Critical thinking, self-evaluation, and lifelong learning skills showed contradictory results. Besides, stressors under individual work environments, including certain Chinese cultural values, affect the way in which dental hygienists utilize PBL skills. This study concludes that the PBL approach is a worthwhile learning process for dental hygiene. However, many different variables affect the effectiveness of applying PBL skills after academic training, especially under the influence of Chinese culture in Hong Kong.
