본 연구는 문제중심학습(PBL) 수업을 2018년 2학기 ‘간호과정과 비판적사고’ 교과목에 적용한 후, 비판적 사고성향, 문제해결능력과 전문직 자아개념에 대한 효과를 규명하기 위하여 단일군 전⦁후 설계를 활용한 원시실험 연구이다. G도에 소재한 간호대학생 59명을 대상으로 자가보고식 설문을 실시하였다. 문제중심학습(PBL) 수업은 전통식 강의 8주, 문제중심학습(PBL) 수업 4주로 진행하였다. 자료분석은 SPSS/WIN 23.0 프로그램을 이용하였으며 일반적 특성은 빈도와 백분율, 두군 간에 차이는 평균, 표준편차, Paired t-test를 시행하였다. 연구결과, 간호대학생의 비판적 사고성향은 문제중심학습(PBL) 수업 전 (3.41±.40)보다 수업 후(3.71±.36)에 유의하게 증가하였다(t=4.39, p<.001). 문제해결능력은 문제중심학습(PBL) 수업 전(3.36±.38)보다 수업 후(3.70±.59)에 유의하게 증가하였다(t=3.97, p<.001). 전문직 자아 개념은 문제중심학습(PBL) 수업 전(2.92±.28)보다 수업 후(3.22±.50)에 유의하게 증가하였다(t=4.84, p<.001). 따라서 문제중심학습(PBL)을 간호교육에 더욱 확대하여 적용한다면 간호대학생이 갖추어야 할 핵심역량을 높이는데 효과적일 것이라고 사료된다.
This study applied the PBL class to the 'Nursing Process and Critical Thinking' courses in the second semester of 2018, and is a primitive research that utilized a single-group, pretest-posttest experimental design in order to examine the effects of the class on Critical Thinking Disposition, Problem Solving Ability, and Professional Self-Concept. Self-report questionnaires were administered to 59 nursing college students in G province. The PBL class consisted of 8 weeks of traditional lectures and 4 weeks of PBL classes. The SPSS/WIN 23.0 program was used for data analysis. Frequency and percentage were used to analyze the general characteristics, and mean, standard deviation and paired t-test were used to analyze the difference between the two groups. As a result, the Critical thinking Disposition of nursing college students was significantly increased(t=4.39, p<.001) after PBL class(3.71±.36) than before PBL class(3.41±.40). The Problem Solving Ability was notably improved(t=3.97, p<.001) after PBL class(3.70±.59) than before PBL class(3.36±.38). The Professional Self-Concept was considerably increased(t=4.84, p<.001) after PBL class(3.22±.50) compared to before PBL class(2.92±.28). Therefore, applying Problem-Based Learning in nursing education to a greater extent is estimated to be effective in increasing the core competencies of nursing college students.
