Abstract

Oceanic current and circulation have played an important role as regulators of the earth's energy distribution. The science and earth science textbooks for secondary schools based on the 2015 revised curriculum included a misconception of the seasonal variation of the North Korea Cold Current (NKCC) among the currents around the Korean Peninsula. To analyze this, the contents related to the NKCC were collected in the textbooks of five middle and six high schools, and a questionnaire survey was conducted on 30 middle school science teachers. The survey consisted of questions about whether the textbook mentions the NKCC and whether there is an error in the concept of the temporal variation of the NKCC, and the teachers' free opinions related to the NKCC were collected. The textbooks suggest that the NKCC is strongest in winter, which is not consistent with scientific findings so far. In fact, there is scientific evidence that the NKCC is the strongest in the summer. In this study, the causes and processes of misconceptions were investigated. According to an analysis of the survey, most teachers had an knowledge that the NKCC is stronger in winter. These errors began with a misconception of the terms, which teachers had imprinted on their memory as firm knowledge. These misconceptions originated from the knowledge that teachers themselves acquired from their secondary school years and have long been transferred back to teachers and students without revising the misconceptions of textbooks. This situation is expected to have a seriously recurrent structure that produces students' serious misconceptions in the future. Therefore, this study summarizes existing results on the seasonal variability of the NKCC and suggests the necessity for re-education to improve teachers' professionalism and to eliminate the misconceptions of teachers and students.

해류와 해양 순환은 지구의 에너지를 분배하는 조절자로서 중요한 역할을 하고 있다. 2015 개정 교육과정에 기반한 중등학교 과학 및 지구과학 교과서에는 한반도 주변 해류 중 북한한류의 계절변동성에 대한 오개념을 포함하고 있는 것으로 드러났다. 이를 분석하기 위하여 중학교 5종, 고등학교 6종 교과서에 제시되어 있는 북한한류와 관련된 교과내용을 수집하였으며, 중등학교 과학교사 30인을 대상으로 해류와 북한한류에 관한 설문 조사를 실시하였다. 설문 내용은 교과서에서 북한한류에 대해서 언급하고 있는지, 북한한류의 시간변동성에 대한 개념의 오류가 있는지에 관한 질문으로 구성하였고, 북한한류와 관련된 자유로운 의견을 수집하였다. 교과서에서는 북한한류의 유속이 겨울에 강하다고 제시되어 있는데, 이는 그동안 장기간의 과학계의 연구 결과와는 정반대로 배치되는 결과이다. 북한한류의 세기는 여름에 강함에도 불구하고 겨울에 강하다고 교과서에서 제시하고 있는 것에 대한 오개념의 원인과 형성 과정을 조사하였다. 교사대상 설문을 분석한 결과, 대부분의 교사들이 북한한류의 세기가 겨울에 강하다는 지식 오류를 가지고 있었다. 이는 교사들이 가지고 있는 용어에 대한 오개념에서 출발하여 교사들의 확고한 지식으로 각인되어 있었다. 이러한 오개념은 교사 자신이 중등학교 재학시절부터 획득한 지식에서 기원하였고, 교과서의 오개념은 수정되지 않은 상태로 오랫동안 교사와 학생들에게 전달되고 있었다. 이러한 상황은 향후 학생들의 오개념을 재생산하는 구조를 가질 수 있을 것으로 예상된다. 따라서 본 연구는 교사 및 학생들이 가지고 있는 북한한류의 계절변동성에 관한 오개념을 단절하기 위하여 기존의 과학적 연구 결과들의 요약하였고, 교과서 수정의 필요성과 교사 전문성 신장을 위한 재교육의 필요성을 제안하였다.
