본 연구는 마음빼기 명상이 중학생의 학교 및 일상 생활에 가져온 변화를 파악하기 위하여 개념도 분석을 실시하였다. 19명의 학생들이 직접 작성한 진술문을 바탕으로 수집된 자료는 엑셀을 사용하여 개인 유사성 행렬표와 집단 유사성 행렬표(Group Similarity Matrix: GSM)로 정리 되었다. GSM을 이용하여 SPSS에서 다차원척도(Multidimensional Scaling: MDS) 분석을 실시하여 각 진술문이 2차원 좌표 상의 어디에 위치하는지를 확인하였다. 본 연구에서는 MDS의 결과로 산출된 차원(Dimension)을 바탕으로 Ward 방법으로 위계적 군집 분석(Hierarchical Cluster Analysis: HCA)을 실시한 후 덴드로그램을 체크하였다. 연구결과는 학교기반 마음빼기 명상의 효과는 4개의 군집으로 묶을 수 있는 것으로 나타났다. 이 4개의 군집은 자기성찰력 향상(내면의 성장), 대인관계향상(친구, 가족), 수업태도 향상(집중, 성실), 그리고 긍정적 정서(스트레스, 화 감소)로 명명되었다.This study conducted a concept mapping analysis in order to find out the effects of Mind-Subtraction Meditation practiced by 19 middle school students as part of a school-based meditation program. The program was carried out for 17 weeks, twice a week with each session lasting 45 minutes, under the guidance of two trained meditation teachers. For the purpose of the research, the six steps of concept mapping process proposed by Trochim were employed. Two rounds of data collection were carried out. First, the students were solicited to write about the effects of the Mind-Subtraction Meditation, and 61 statements were generated as a result of the first survey. Second, the students were asked to rate the importance of each statements generated by themselves while categorizing each statements. These data were analyzed by SPSS using Multimensional Scaling(MDS) technique. The MDS analysis showed a visual point in which each statement was located in two dimensional graph and Hierarchical Cluster Analysis(HCA) helped to determine the number of cluster of the statements. The HCA resulted in four clusters as the effects of Mind-Subtraction Meditation. The four clusters were labelled as the improvement of self-reflection(inner growth), of interpersonal relationships(friends, family), of attitude towards class(concentration, diligence) and of positive affect(diminishing stress and anger). The implications of the results were discussed along with the potential of the concept mapping as a research methodology useful in capturing subjective perceptions or phenomena in a systematic way.
