이 연구에서 우리는 초등학교 교사들이 생각하는 ‘지층’ 단원에서 배워야만 한다고 생각하는 용어와 개념들에 대해 조사하였다. 특히, 개정된 교육과정의 변화에 따라 새롭게 등장하거나 사라진 개념들에 초점을 맞추어서 현직 교사들의 생각을 알아보았다. 또한 우리는 2007, 2009, 2015 개정 교육과정에서 제시된 각각의 성취 기준들과 각각의 교육과정 상의 교과서 탐구 활동 중에서 ‘지층’ 단원을 가르치기에 적절한 것은 무엇인지 알아보았다. 연구는 101명의 초등학교 교사들을 대상으로 이루어졌으며 그 결과는 다음과 같다. 첫째, 교사들은 ‘지층’, ‘퇴적암’, ‘화석’, ‘암석’과 같은 용어들은 배워야만 한다고 생각하였다. 개별적인 암석명의 경우는 암석명에 따라 의견이 조금씩 달랐다. 둘째, 교사들은 ‘암석’, ‘단층’과 같은 개념들은 기본적이며 이해 가능한 개념들이기 때문에 학생들이 배워야하는 개념이라고 생각하였다. 셋째, 학생들의 수행 가능성은 적절한 성취기준을 결정하는 가장 중요한 기준이었다. 넷째, 교육과정 성취기준과 관련 탐구활동 간의 상관관계가 매우 낮았다. 연구 결과, 교사가 가르치는 데 필요하다고 생각하는 용어, 개념, 성취기준, 탐구활동 등은 현재 적용되는 교과서에서 제시한 내용과 차이가 있는 것으로 나타났다. 그러나 현행 교육과정에서는 학습 내용과 교수법이 지나치게 엄밀하게 제시되어 있기 때문에 교사가 원하는 방식으로 학생을 가르칠 수 없고 그 결과 학생들의 수업에 부정적인 영향을 미칠 수 있다. In this study, we investigated the terms and concepts that form part of instruction in the stratum unit, as indicated by elementary school teachers. In particular, we examined the ideas of in-service teachers, focusing on concepts that disappeared or appeared for the first time in the course of revision of the curriculum. We also looked at what was appropriate to teach the stratum unit in the revised curriculum achievement criteria for 2007, 2009, and 2015 and the accompanying textbook inquire activities. In this study, a total of 101 elementary school teachers participated, and the results were as follows. First, the teachers believed that the terms stratum, sedimentary rock, fossil, and rock must be explicitly taught. For the individual rock names, they presented a range of opinions depending on particular rock. Second, because concepts such as rock and fault are fundamental and understandable concepts they thought that the concepts must be learned. Third, students’ ability to perform was the most important criterion in determining appropriate achievement criteria. Fourth, the correlation between the curriculum achievement criteria and the associated inquire activities was very low. As a result of the research, it was found that the terms, concepts, achievement criteria, and inquiry activities that teachers reported needing to teach differ from what is found in currently textbooks. However, in the current curriculum, because learning content and teaching methods are presented too rigorously, teachers cannot teach students in the way they want, which can negatively affect students’ instruction.

과학 탐구 활동의 유형과 과학 탐구의 특징에 대한 초등학생의 인식

This study investigated elementary students’ perception of the suitability of inquiry activities related to the science inquiry, essential features of the inquiry and essential features of the inquiry by science inquiry activities. First, 5-6th grade elementary students’ perception of the suitability of inquiry activities to the science inquiry was positive in this study and especially the score of experiment and field trip was high. The lowest score was on the discussion and elementary students thought that discussion might be wrong, because they just talked when they participated in the discussion. Second, perception of the essential features of science inquiry was positive. Especially, engaging students in evaluating their explanations in the light of alternative explanations was the highest. Students thought that explanation is important, but it is too hard to perform the science inquiry with only the explanation. Third, the score of research and experiment was high in essential features of science inquiry by science inquiry activities. The score of the field trip was low, so a more meaningful field trip should be carried out in the school.

한일 국교 정상화 전후 부산의 일본인 유골 문제를 둘러싼 위령(慰霊)의 정치

This study aims to examine how the private and national levels of both Korea and Japan have responded to a series of incidents, such as the disposal of remains and memorial tablets left in the Japanese cemetery due to Busans urban development plan, before and after the normalization of diplomatic relations between Korea and Japan. Until now, many studies have been conducted in both Korea and Japan regarding deaths during the Asia-Pacific War, but these have primarily focused on soldiers. Specifically, in Korea, the focus has been on Korean remains, with Japanese remains in Korea only incidentally mentioned in relation to Korean remains research. Therefore, this study acknowledges that both Countries have overlooked research concerning the investigation and repatriation of the remains of colonists who died in the colonial city of Busan. It aims to expand the scope of the study beyond the existing focus on the politics of Japanese dead, primarily centered on the relocation of comforting the spirits of deceased Japanese, to encompass the significance of rituals related to Japanese civilian deaths in colonies. Before and after the political agreement between the two countries to normalize diplomatic relations between Korea and Japan, the civilian level of Korea and Japan consoled the dead against the backdrop of their own view of death. On the contrary, at the national level, both contries are responding to and dealing with Japanese remains based on political judgment. Meanwhile, the Japanese side has been continuing the politics of comforting the spirits by putting a private organization composed of Japanese individuals in Busan at the forefront as the organizer.

연구의 목적은 과학 체험학습을 운영하는 과정에서 초등교사가 겪는 어려움과 학교 현장의 분위기를 심층적으로 알아보고자 한 것이다. 본 연구를 위해 과학 체험학습의 활동 경험이 풍부한 5명의 초등교사와 초점집단 면담을 진행하였다. 면담을 통해 체험학습의 운영실태, 과학체험학습의 운영, 계획 수립 및 진행, 평가에 걸쳐 자료를 수집하였다. 본 연구의 주된 결과는 다음과 같다. 교사들은 예산에 대한 고민을 가장 먼저 꼽았으며, 과학교과와 연계하여 체험학습을 운영하고자 하는 경우 교육과정 재구성에 대하여 부담을 지니고 있었다. 또한 과학 체험학습시 과학지식에 대한 전문적 이해가 부족하다고 생각하고 있었으며, 과학교과 전담 교사가 있을 경우 협업의 어려움을 꼽았다. 전체적으로 과학 체험학습의 교육적 효과보다 예산이나 장소, 행정적 편의성 등을 먼저 고려하는 경향이 있었다. 본 연구는 기존의 연구들에서 확인하기 어려운 체험학습 주제 선정과 방법, 교육적 기대효과, 고민사항을 확인한 연구로서 의미가 있다. The purpose of this study is to identify the difficulties that elementary school teachers face and the atmosphere of school fields in depth in the course of conducting science experiential learning. For this study, we conducted focus group interviews with five elementary school teachers who have had rich experiences in science field studies. Through interviews, the actual state of experiential learning operation, the operation of science experiential learning including planning, progress and evaluation of experiential learning operation. The main results of this study are as follows: Teachers were most concerned about budget, and were burdened with curriculum reconstruction for science experiential learning. In addition, teachers expressed their lack of expert scientific knowledge with science experiential learning, and difficulties with collaboration with science-specialized teachers. In sum, teachers consider budget, site, and administrative convenience first, rather than effects of science experiential learning. The significance of this study is identifying the selection of topics, methods, educational expectations, and problems of science experiential learning topics, which were difficult to identify in previous studies.
