We attempted to develop a problem-based learning (PBL) module for integrated education in dental hygiene with the aim of helping students gain clinical competencies necessary for dental hygienist work. To develop the PBL Module for Clinical Dentistry in Dental Hygiene course, the researchers identified literature related to not only educational technology, but also medical science, nursing, dentistry, and dental hygiene. During the design phase of the PBL module, problem scenarios and a plan for the teaching and learning process were developed. Developing problem scenarios involved describing a problematic situation and three questions related with that situation. To cultivate competencies required in dental clinics, each question was related to the diagnosis of a dental disease, dental treatment, and dental hygiene procedures for care. Teaching-learning process plan included the designs of operating environment, operational strategies, learning resources, facilitation of problem-solving process, and evaluation. It is necessary to evaluate the PBL module for integrated education in dental hygiene to confirm its effectiveness.Key Words: Clinical dentistry, Education, Problem-based learning
IntroductionDental hygiene education in Korea began with the introduction of a 2-year curriculum in 1965 by the Severance Hospital affiliated with College of Medicine at Yonsei University, which was based on dental hygienist training program from Fones School of Dental Hygiene in the United States. Contrary to the goal of dental hygienist training that focuses on preventive duties, dental hygiene education at the time consisted of theoretical and practical education on assistance for care 1) . In 1994, dental hygiene education throughout Korea was converted to a 3-year curriculum, and the development of a 4-year curriculum in 2002 has led to an extension of the schooling, along with an increase in the number of well-qualified dental hygienists to date 1) .Existing dental hygiene education has several problems, such as the content being excessively segmented into too many courses, the courses not being focused on dental hygiene, courses being dentistry-based, focusing on the duties of dental care assistance, without any consideration for the various roles that dental hygienists play 2,3) .Course-based education may lead to content overlapping with other courses or certain lessons not being taught based on the belief that these would be taught in other courses 4) . Moreover, because the curriculum progresses in no logical order, blended learning between courses becomes difficult, which limits the students' ability to build interdisciplinary integrative thinking 4) . Additionally, dentistry-based education has the goal of disease treatment, and its focus on dental care assistance duties differ from the duties of dental hygienists, whose goal is health promotion. This presents difficulties for the dental hygiene students in gaining comprehensive understanding and in applying what they learn to actual work situations. This ultimatel...
