  • In this study, the experimental apparatus for boiling point and melting point in science textbooks of various curriculums were analyzed. Science teachers' views on the difference between the experimental value and the value written in textbooks were inquired, too. Their views on the experimental apparatus, nd results of freezing point,melting point, boiling point, fractional distillation, and thermometer calibration were also investigated. The results of this study showed that the types of experimental apparatus for boiling point and melting point were somewhat dif-ferent with science textbooks and curriculum. The teachers' views were also various according to their background. In the experiment of the fractional distillat ion, a large number of teachers recognized mismatch between the exper-imental value and the value written in textbooks as mistake of textbook contents or problem of experiment itself. The teachers of chemistry background take higher recognition of the requirement of thermometer calibration than those of non-chemistry background in middle school.

  • With recent surge of Internet use, many people become concerned with side effects of Internet. Especially Internet addiction has become a significant issue. As Internet users become much younger than before, Internet addiction is salient even among elementary school students. While much research has been conducted on adolescents' addiction, only a little research has been conducted on elementary students' Internet addiction. In addition, it is necessary to use a standardized and reliable evaluation tool that is designed to assess the level of children's and adolescents' Internet addiction. The purpose of this study is to grasp the realities of elementary students' Internet addiction using an evaluation tool developed for elementary and secondary students, and to analyze the factors affecting Internet addiction. A survey was conducted to 1,382 5th and 6th graders selected from nationwide schools. The results of this study shows that 5.5% of the sample students are in the stage of serious addiction, and 12.4% in the stage of early addiction. In addition, the degree of Internet addiction significantly differs by various variables such as demographic factors, the experience of Internet use, family-related traits, and social activities.

  • The purpose of this study is to examine how the learning experience understanding degree and radian as the measurement of arc affects the conceptual understanding of radian and measuring angle. For this purpose, we investigated pre-service teachers' understanding about measurement of angle using a length of arc, and then conducted a teaching experiment with two middle school students. The results of analyzing pre-service teachers' and students' response are as follows. Students' experience interpreting the concept of degree into measurement of arc had a positive effect on understanding of radian and students' learning process in which they got measurement of angle as measurement of arc enabled conceptual understanding of 'linear measuring'. Also a circle context and a strategy dividing by arc operated as effective strategies for solving various problems about an angle. Finally, we confirmed that providing direct manipulative activities as a chance to explore relationships between an angle and arc measure can help students' conceptual understanding of measuring angle.

  • 우리들은 초 중등교육을 통해 암석의 종류와 특징, 지질형태와 퇴적구조, 그리고 화석에 대해 지속적으로 교육 받아왔다. 그러나 암석이나 노두를 보고 학교에서 배운 지식을 바르게 적용할 수 있는 학생은 매우 드물다. 또한 아름다운 경관을 보며 지질학적으로 형성과정을 해석할 수 있는 사람도 매우 드물 것이다. 여기서는 지질경관에 대한 정보를 어떻게 제공하고 있는가에 대한 연구 성과를 정리해보고 문제점을 도출하고자 한다. 현재까지 지질경관을 알려주는 연구 성과를 크게 나누면 3종류가 있다. 첫째, 지질학습장의 개발 및 활용에 관한 연구이다. 이 부류의 수집된 자료는 학위논문(29편)과 전문학술지(27편)로 현재 56편이나 검색에 따라 더 늘어날 것이다. 이들은 야외 노두에 대한 효과적인 지질학습을 위한 자료개발을 위주로 하고 있다. 이러한 내용들은 전문가 양성에는 대단히 좋은 프로그램이지만 청소년이나 일반대중들에게 너무 어려운 내용으로 구성되어 있다. 또한 교육청에서 주관하는 탐방계획으로 "경기도 지구과학교사 연구회"가 있는데, 주로 경기도 한탄강유역을 대상으로 하고 있다. 이 연구회 자료에서는 지역의 특성을 살린 야외지질학습장을 개발하고 현장에 적용하기 위한 노력을 볼 수가 있다. 두 번째로 과학전람회 자료로서 현장교사와 학생들의 야외학습에 대한 인식이 잘 나타나 있다. 수집된 자료는 총 55편으로 야외지질조사를 통해 관찰 자체에 중점을 두었는데, 최근에는 노두관찰에 덧붙여 탐구학습 태도와 창의성을 함양하는 쪽으로 옮겨가고 있다. 세 번째 자료는 일반대중을 위한 서적이다. 이 서적들은 저자들의 전공에 따라 그 내용이 다소 다르다. 즉 일반여행안내 책자는 노두나 암석은 소개하고 있으나 지질학적 설명이 전혀없으며(예, 남도해안 2000리), 지리학자들의 저술에는 지형의 형성을 지질학적으로 설명하려 애쓴 흔적이 보인다(예, 한국지리이야기). 다음으로 지구과학들의 저술은 전형적인 지질답사 안내서에 가까워 내용 자체는 좋으나 흥미가 다소 떨어진다(예, 가족이 함께 떠나는 지질여행, 제주도 지질여행). 지질학과 흥미를 적절히 혼합한 책으로 '우리 땅 과학 답사기'정도가 있다. 최근 한국암석학회에서는 "우리의 명산"을 지질과 경관의 관점에서 해석하려는 심포지엄을 2차례 가졌다. 그러나 그 내용면에서는 경관지질이라는 개념을 정립했다고 보기에는 다소 미흡 하나, 황상구 교수의 주왕산에 관한 내용은 앞으로 경관지질 연구에 대한 발전의 여지를 보여주었다. 앞으로 지질경관에 대하여 지질학적 야외답사나 과학지식 습득에 국한시키지 말고, 그 지역의 특성을 살린 관광 또는 민속과 연계하여 지구과학적 학습효과와 더불어 인성교육에 도움이 되는 학습 콘텐츠를 개발하도록 노력해야 할 것이다. 일반 대중이 우리나라의 빼어난 지질 경관을 손쉽게 이해하고 즐기게 되면, 세계자연유산이나 세계지질공원을 지정 받는 과정도 더 쉬워질 것이다.

  • This study was conducted to evaluate the effectiveness of a polar literacy education program for elementary and middle school students, and to derive implications for new education to respond to climate change. We developed modular education programs based on the seven principles of polar literacy established by the Polar-ICE team. We divided them into two courses, one emphasizing science concepts and another emphasizing humanities and sociological issues. We then selected and structured detailed programs suitable for the two courses. These two courses were applied to 26 elementary and middle school students for approximately 69 hours in a Saturday science class hosted by the Department of Science Education at a university in Seoul. The 26 students were divided into three groups. Two groups completed the science education program for polar literacy and a humanities and social studies education program for polar literacy, respectively. The third group, the control group, received general science education unrelated to polar literacy. Before and after running the programs, all three groups responded to a polar literacy test and questionnaires that used vocabulary and presented scenes associated with polar regions. The test results were expressed using Wilcoxon signed ranks, which is a non-parametric test method, and improvements made upon completion of the program were analyzed. From a cognitive aspect, all three groups showed improvement after completing the program in the knowledge area; however, the experimental groups showed a greater degree of improvement than the control group, and there was a clear difference in the contents or materials explicitly covered. From an affective aspect, the difference between before and after the program was minor, but the group that focused on humanities and social issues showed a statistically significant improvement. Regarding changes in polar imagery, the two experimental groups tended to diverge from monotonous images to more diverse images compared to the control group. Based on the above results, we suggested methods to increase the effectiveness of polar literacy education programs, the importance of polar literacy as appropriate material for scientific thinking and earth system education, measures to improve attitudes related to the polar region, and the need to link to school curriculums.

  • Teachers play a key role in designing a students' learning experience. Teachers are asked to interpret the context in which they are located and to adjust their practice to fit circumstantial needs based on their teacher agency. In this study, we explore the emergence of teacher agency in distance learning caused by COVID-19 and we analyze factors shaping the teacher agency. For this purpose, we interviewed six secondary science teachers who practiced distance learning in 2020. Semi-constructed interviews and their artifacts were collected and analyzed. This study shows that teacher agency is captured when they respond to circumstantial change and modify their practice to achieve their professional purpose or adjust their practice in space for maneuvering or keep their practice consistent. This study also analyzes the factors that affect the emergence of teacher agency in two dimensions. One is individual and the other is contextual. In the individual dimension, educational values shaped by his/her experiences and short/long-term goals for the future support the emergence of teacher agency. In the contextual dimension, there are collaborative and flexible culture shared by the community, co-operation within the teacher community, and material support. On the other hand, in the individual dimension, the teachers' sense of their role, and no reflection for own practice constrain the emergence of teacher agency, and in the contextual dimension, performativity discourse and strong requirement without guidance constrain the emergence of teacher agency. We suggest an effective lens for establishing a strategy that support teachers' professional practice and the emergence of teacher agency.

  • This program aimed at preparing the pre-service teachers to teach about North Korean family life culture to secondary school students, by promoting the understanding and acceptance of cultural differences between the two Koreas. Based on the literature review, the educational contents were developed to reflect general aspects of North Korean family life. The program was implemented with 35 undergraduate students in a home economics teacher education program. The program consists of 15 units of 150-minute instructional sessions. The first three introductory sessions dealt with the definitions of family life culture and multiculturalism, as well as a historical review of South-North relationship. The following nine sessions were devoted to North Korean family life culture in five different domains: consumption and leisure, family and child-caring, food and dietary life, housing and neighborhood life, and clothing/fashion. During the final two weeks, pre-service teachers conducted mock-teaching. For evaluation, pre- and post-session scores on general teaching efficacy and understanding of cultural differences were compared using paired t-tests. The pre-/post-test results confirmed that the program was successful in promoting the understanding and acceptance of cultural differences between two Koreas of pre-service teachers.

  • This study is to develop teaching materials for geological fieldwork around Bonghwabong area in the national park of the Byeonsan Peninsula, Buangun, Jeonbuk. The developed materials are applied in the geological fieldwork of science high school students to maximize the effects of use. The sedimentary succession of the Bonghwabong area in the Cretaceous age, Mesozoic, represents large-scale and distinctive sedimentary structures on the sea cliffs, which are utilized as teaching materials for earth science fieldwork. The area of Bonghwabong also comprises various geological structures related to advanced learning programs as well as those within the curriculum of high school earth science. A five-step fieldwork model was applied to 15 students in clubs related to earth science in a science high school. This study used a qualitative methodology to analyze students' responses that were gathered about the process of fieldwork. During the activity, a qualitative analysis was carried out by using discussions and interviews both with the students and the teacher. Results indicated that the fieldwork activity using teaching materials was effective in helping the students improve their self-directed learning and practical understanding of earth science.

  • This study is to analyze on territorial education described in geography textbooks in Korea and Japan. The following is the result that shows similarities and differences of the geography textbooks when it comes to territorial education. Korea and Japan have a contrasting territorial background. However, both countries start their territorial education by learning the location and shape of their country. Japanese geography textbooks focus on what people in the world think of Japan, but in case of Korea, the geography textbooks focus on how Koreans look at the world. In short, the territorial education in Japan try to emphasize Japan from the view point of the world. The next common ground is that the two countries provide territorial models in their geography textbooks in order to increase understanding. However, the Japanese students are provided with these territory models much earlier than Korean students and these models help them visualize and solidify their concept of territory. And, the two countries both put great importance on teaching territorial sea. In Japan, they try to include EEZ(Exclusive Economic Zone) in their territory. Considering these facts, it can be concluded that Japan is enlarging their concept of national territory as maritime territory. Lastly, after learning of territory the two countries both treat on territorial problems. But Korea treats passively territorial problem as such Dokdo, but Japan treats actively their territorial problems. Like that, the contents of territorial education described in geography textbooks in Korea and Japan are similar in terms of selection, but differ in quality in terms of organization. Therefore, future territorial education in Korea will be actively and successively done through succession and sequence of geography curriculum.
