  • The purpose of this study was to assess pro-environmental behavior of elementary school students by school year and gender and to investigate the relationships of their emotional affinity toward and intellectual curiosity about life, and experiences about nature and life with the pro-environmental behavior. A total of 436 elementary students participated in the study: 189 3rd grade; 247 6th grade students, and 233 boys; 203 girls. The variables were measured by using a self-report questionnaire with 5-point Likert scale items. The results showed the levels of pro-environmental behavior of the 3rd grade students and the girls were higher than that of the 6th grade and the boys, respectively. Their pro-environmental behavior was significantly related with all measured variables. However, it was found that the direct predictors of their pro-environmental behavior were the intellectual curiosity and the indirect experience, while the emotional affinity and the direct experience did not have a direct impact on the behavior. The predictive power of the intellectual curiosity and the indirect experience for their pro-environmental behavior was higher in 3rd grade than 6th grade. While the indirect experience was a stronger predictor of the boys' pro-environmental behavior than the intellectual curiosity, the curiosity was a stronger predictor of the girls.

  • 급격한 산업 성장 시기 전문기능·기술인을 양성하던 특성화고등학교가 학령인구의 감소, 노동시장의 인력수요 변화, 기능직에 대한 차별 등으로 인해 입시경쟁에서 밀려난 하위권 학생들이 진학하는 고등학교로 변하였다. 중학생들이 특성화고등학교에 진학을 결정하는데 타인의 영향을 받았을 때 중학교 교사의 영향(23.69%)을 가장 크게 받는다고 선행 연구에서 밝히고 있다. 즉, 중학교 3학년 담임교사들의 조기 진로지도를 통하여 성적이 아니라 적성과 소질에 따라서 특성화고등학교 진학을 결정할 수 있도록 도울 수 있다. 이를 위해 중학교 3학년 담임교사의 일반적인 특성과 인식에 따른 학생의 특성화 고등학교 진학 결정률의 관계를 조사하였으며, 2018년 대전광역시에 있는 중학교 3학년 담임교사를 대상으로 조사 연구를 하였다. 그 결과 담임교사가 남자일 때 21.01%(M=.2101)의 학생들이 특성화고등학교에 진학하는 것으로 나타났으며, 남녀 교사 간에도 학생들의 특성화고 진학률에 통계적으로 유의미한 차이가 있었다. 그리고 비사범대 출신(M=.2110), 박사인 경우(M=.3064) 상대적으로 특성화고등학교에 진학을 결정할 확률이 높았다. 교사의 인식에 따라서는 '특성화고등학교 학과에 대한 이해(β1)'와 '고졸 취업에 대한 긍정적 인식(β2)'이 같이 높아질 때 '특성화고등학교 진학 결정(y)'에 긍정적인 영향을 미치는 것으로 나타났으며 그 설명력은 10.1%이고, 이를 바탕으로 도출한 회귀식은 y = -0.56 + 0.037*β1 + 0.025*β2 10.1%(R2=0.101)이었다.
