Critical Experiments (CE) in science classrooms mean, tentatively, critical situations as comparable to anomalous cases in scientific revolutions where the results of science experiments in schools are unclear, differ from the theory, or students misunderstand the purpose of the experiments. The purpose of this research is to identify what CE occurred during science classes and to investigate how elementary teachers handled them. To analyze how teachers recognized and handled CE, we selected nine typical CE from the $7^{th}$ Korean science curriculum. 125 teachers were selected from 8 districts' elementary schools in a local city. A questionnaire with photos of the nine CE above-mentioned was distributed to these teachers. The focus in this research was the way that each teacher handled the CE. We discovered that there were three basic ways in which teachers handled CE. When CE occurred, 51% of elementary teachers explained the correct result of the experiment (what should have happened) to the students while 40.7% of the teachers repeated to get the correct results. The focuses of handling CE varied. 57 % of the teachers focused on the 'materials' while 30% of the teachers focused on the 'theory'. The other focus was 'thinking'. Only 7.6% of the teachers answered that they gave students a chance to think about the reasons why the CE happened. By analyzing our survey results, we could determine what each teacher did as a follow up to the CE and their focus and reasoning for handling the CE this way. When the CE happened in the science class, few handled the CE with the point of view about purpose of doing experiment. As a result, students could not gain educational experience from the CE. If we use CE as a new method to teach science, it will be a good subject incorporating the nature of science in science education.

다이어그램은 수학 문장제의 구조를 표현하고 추론을 하여 문제를 해결하는 데 유용하다. 다이어그램에 관한 교사의 관념과 실행은 학생들에게 큰 영향을 미친다. 그러므로 예비교사교육 프로그램에서 예비교사들이 다이어그램 관련 역량을 기를 기회를 제공해야 한다. 관련하여, 예비교사들이 다이어그램에 대한 어떤 사전 경험과 관념을 가지고 교사교육 프로그램에 입문하는지, 프로그램을 거치면서 어떤 변화가 일어나는지, 프로그램에 어떤 개선이 필요한지 연구할 필요가 있다. 이 논문에서는 그 출발점 작업으로, 교육대학교의 수학교육 프로그램에 입문하는 초등예비교사들의 다이어그램에 대한 관념과 수행을 조사하였다. 조사 결과, 초등예비교사들은 다이어그램 유용성 인식과 다이어그램 교육 의지 영역에서 긍정적인 응답을 보였으나, 수학 문장제 해결에 다이어그램을 자발적으로 사용하고 있지 않았고 학교에서의 다이어그램 학습 경험에서도 부정적인 응답을 보였다. 또, 초등예비교사들이 그린 다이어그램을 분석한 결과, 해를 구하는 추론 (풀이) 과정을 나타내는 다이어그램을 그린 초등예비교사는 소수였다. 이러한 결과는 다이어그램에 관한 경험과 지식이 부족한 상태로 수학교육 프로그램에 입문하는 초등예비교사가 많음을 시사한다.

The purpose of this study was to analyze students', preservice teachers and inservice teachers' images of scientists. For the purpose of this study, we selected 711 people. The results generally was showed the students, preservice teachers and inservice teachers have the stereotyped image of scientists. When we group the subject of investigation as elementary-school students, middle-school students, high-school students, preservice teachers, inservice elementary-school teachers, and looked into whether there were meaningful differences among them by the method of ANOVA, we could see the meaningful differences (p<0.05). And also elementary-school students showed the meaningful difference from other groups when examined on the $Scheff{\acute{e}}$ test.

Although constructivist assessment has been emphasized by many science educators, most elementary school teachers are still not familiar with this. In order to investigate the causes of this problem, we examined the perceptions of pre-service elementary school teachers toward constructivist science assessment and the relationships among the perceptions toward constructivist science assessment, the views on science teaching and learning, science teaching efficacy beliefs, and the perceptions toward constructivist science learning environment. Analyses of the results revealed that the perceptions of pre-service elementary school teachers toward constructivist science assessment were higher than those of the elementary school teachers reported previously. The results of a stepwise multiple regression analysis indicated that the views on constructivist science teaching and learning and personal science teaching efficacy beliefs were the significant predictors of the perceptions toward constructivist science assessment.

This study used questionnaires to investigate how pre-service elementary teachers understand ocean acidification. As a result of gender, female teachers were more aware of ocean acidification than male teachers, but male teachers had a higher average rate of correct answers, with a lower standard deviation. Teachers from the natural sciences knew more about ocean acidification than did teachers the liberal arts. Teachers ranked environmental crisis in order of most dangerous to least dangerous as follow: global warming and the greenhouse effect, ozone depletion, ocean acidification, and acid rain. About 46.7% of teachers learn about ocean acidification through education, followed by broadcasts, school lectures and the internet. The educational materials most desired for teachers were videos related to ocean acidification. Pre-service elementary teachers have two broad perspectives on ocean acidification. Firstly, they refer to economic loss and food shortages, and secondly, they note that there is a need for improved awareness and publicity about ocean acidification. The role of elementary school teachers is important because their awareness of environmental issues has a considerable effect on teachers perception of the environment. Revitalizing education on ocean acidification and government support are necessary to effectively communicate the seriousness of ocean acidification. Lastly, we need to study ocean acidification in detail so as to be able to persevere toward protecting our ocean ecosystem.

The purpose of this study was to investigate the environmental awareness and attitude of elementary school teachers. For this study, 100 elementary school teachers from H graduate school of education were sampled. The results of this study were summarized as follows. First, the biggest concern of environmental problems were water-pollution and garbage problems by the lack of understanding about the environment and injudicious development. Second, most teachers recognized the need for environmental education and they answered that they were doing best to teach students with the main purpose of helping them develop values of environmental preservation. Third, most environmental education was carried out during class using current events and the emphasis on garbage separation and recycling. They also showed the lack of teaching materials and field trips for environmental education. Fourth, it appeared to come from media-oriented environmental education. Most teachers mainly used newspapers and visual materials. 1'hey were obtaining knowledge and information related to environmental education through the media. Since in-service teachers' conceptions could directly effect present education, it is necessary to establish a more systematic educational system for environmental education, for in-service elementary school teachers.

The purpose of this study was to analyze field application of science subject competences of the 2015 revised curriculum for the second year of application. For this purpose, a survey with 133 elementary school teachers, and in-depth interviews with 10 teachers were conducted. According to the results, elementary school teachers had a positive awareness toward the science subject competence, which is a characteristic of the 2015 revised science curriculum, and teachers were applying the science subject competence to their own classes. This tendency was stronger in teachers in science-leading schools than in teachers in regular schools. Teachers wanted support for applying science subject competencies to their classes. To support this, it is necessary to provide the curriculum materials focused on science subject competencies, reinforce teacher training on competence-related curriculum, and activate the professional teacher community.
