The purpose of this study was to investigate the awareness of elementary school teachers on the socio-scientific issues. Fukushima Nuclear Power Plant Accident was used by concrete issue connected with SSI for this study. Participants in this study were twelve elementary school teachers studying at K University Graduate School of Education, located in the central region, who underwent a semi-structured interview. The study method was the phenomenological research method which is one of the qualitative research methods, and the interview papers had been examined by three scientific experts. As a result of the study, it was divided into twenty six themes, eight theme clusters, and two categories, and considered the thoughts on the Fukushima nuclear power plant accident, its influence on Korea, the relationship between science and society as a result of the Fukushima nuclear power plant accident, interested in social issues related to science, application in class, response from students and the influence on students. Teachers had a general understanding of science-related social issues, but did not have much interest in the subject. However, they mentioned that to apply the issues in the curriculum would have a positive influence and encourage scientific motivation in students and, furthermore, helped them to develop the awareness of science in their surroundings. A greater interest in socio-scientific issues need to require from teachers and, through including these issues in the curriculum, we should have positive influence in developing science education.

The purpose of this study was to compare characteristics of students lived in volcanic region or not while observing the igneous rocks basalt and granite. For the study we recruited 68 fifth-grade students in Jeju Island, 29 fifth-grade students in Ulleung Island and 61 fifth-grade students in inland area area. This study was conducted as follows: After observing of granite and basalt, the students wrote observations. At the end of observation they also wrote all knowledges about granite and basalt except for the observations. The results are as follows: First, igneous rocks observations did not show a statistically significant difference between regional characteristics variables. Second, the amount of knowledge that students knew about granite and basalt except for the observation facts also did not show significant differences. Third, in the results of qualitative analysis for knowledges about granite and basalt except for the observation facts, many students knew about the igneous origin and about the substance but there were few statements that reflected the characteristics of the location . This results will provide a meaningful implication that the science class must consist of the use a various examples associated with a real-life. 이 연구의 목적은 현무암과 화성암과 같은 화성암을 관찰할 때 화성암 지역에 살고 있는 학생들과 그렇지 않은 학생들 사이의 특징을 비교하기 위한 것이다. 연구를 위해 제주도에 살고 있는 5학년 학생 68명, 울릉도에 살고 있는 5학년 학생 28명, 그리고 화산지역과 직접적 관련이 없는 지역의 5학년 학생 61명을 선정하였다. 이 연구는 다음과 같이 진행되었다. 현무암과 화성암을 관찰하게 한 후 학생들은 관찰한 사실을 모두 적었다. 그리고 관찰이 끝난 후 관찰 이외에 현무암과 화성에 대해 알고 있는 사실 모두를 적도록 하였다. 연구를 통해 알게 된 사실은 다음과 같다. 첫째, 화성암 관찰에 있어서 학생들은 지역적 특성 변인에 의한 유의미한 통계적 차이는 보이지 않았다. 둘째, 화성암과 관련하여 학생들이 관찰 이외에 알고 있는 지식의 양 또한 지역적 특성과 관련되어 유의미한 차이를 보이지 않았다. 셋째, 화성암에 대해 관찰 사실 이외에 알고 있는 지식을 질적으로 분석한 결과, 많은 학생들은 화성암의 근원물질이나 생성과정에 대해 알고 있었으나 지역적인 특성을 고려한 진술은 많이 나오지 않았다. 이러한 연구 결과를 통해 우리는 학교에서 이루어지는 과학 수업이 현상을 탐구하는 것뿐만 아니라 현상과 관련된 여러 가지 구체적인 사례들과 함께 이루어져야 한다는 것을 알 수 있다.

The purpose of this study was to investigate the characteristics of high school students’ conceptual understandingabout minerals and rocks. A questionnaire was developed to examine students’ conceptions of minerals and rocks. Thedata were collected from 93 students in 10th and 119 students in 11th grades in a high school. The result showed thatstudents’ understanding of minerals and rock was on the moderate level. The 10th grade students showed a relativelyconcepts related with melting point in the rock domain was a little bit lower than the average. Although theunderstanding levels between the two grade levels were similar, there were some items for which students understandingseemed to be more sophisticated with the grade. In the questions about the characteristic of basalt surface, however, thefrequencies of non-scientific conceptions were not decreased, rather increased along with the grade. It was also found thatthe conceptions students acquired from other science lessons as well as earth science classrooms did rather interfere withstudents’ construction of the scientific concepts of minerals and rocks even though sometimes they were helpful forlearning. It was suggested that the teachers should understand that some specific terms in earth science have differentmeanings as they were used in other subjects.......... minerals, rocks, high school students, scientific concept. . : . ... ... ...... ... ... .. ... ... .... ... . .. ... ... ,

영남육괴 북동부 울진지역 화강암류의 지화학적 특성

위수민,김지영,임성만 한국지구과학회 2013 한국지구과학회지 Vol.34 No.4

Jurassic granitoids in the northeastern part of the Yeongnam Massif are possibly the result of intensivemagmatic activities that occurred in response to subduction of the proto-Pacific plate beneath the northeast portion of theEurasian plate. Geochemical studies on the granitic rocks are carried out in order to constrain the petrogenesis of thegranitic magma and to establish the paleotectonic environment of the area. Whole rock chemical data of the Uljingranitoids in the northeastern part of the Yeongnam Massif indicate that all of the rocks have the characteristics of calc-alkaline series in subalkaline field. The overall major element trends show systematic variations in each granitic body, butthe source materials of each granitoids seem to have different chemical composition. The Uljin granitoids are differentfrom other granitic rocks, which distributed vicinity of the study area, in the contents of Al2O3 and trace elements such asCr, Co, Ni, Sr, Y and Nb. The Uljin granitoids have geochemical features similar to slab-derived adakites such as highAl2O3, Sr contents and high Sr/Y, La/Yb ratios, but they have low Y and Yb contents. The major (SiO2, Al2O3, MgO)and trace element (Sr, Y, La, Yb) contents of the Uljin granitoids fall well within the adakitic field. The Uljin granitoidshave similar geochemical characteristics, paleotectonic environments and intrusion ages to those of the Yatsuo plutonicrocks of Hida belt located on northwestern part of Japan. Chondrite normalized REE patterns show generally enrichedLREEs ((La/Yb)CN=10.6-103.4) and are slight negative to flat Eu anomalies. On the ANK vs. A/CNK and tectonicdiscrimination diagrams, parental magma type of the granites corresponds to I-type and volcanic arc granite (VAG). Interpretations of the chemical characteristics of the granitic rocks favor their emplacement in a compressional tectonicregime at the continental margin during the subduction of Izanagi plate in Jurassic period. 영남육괴 북동부에 분포하는 쥐라기 심성암체들은 유라시아대륙의 동북부지역 아래로 고태평양판의 섭입에 의해서 야기된 활발했던 화성활동의 산물이다. 지화학적 연구를 통하여 이 지역에 분포하는 화강암류의 성인과 지구조환경을 유추하여 보았다. 영남육괴 북동부에 위치하는 울진화강암류는 비알칼리(subalkaline)영역에 속하는 칼크-알칼리(calc-alkaline)계열로, 분화에 따른 주성분원소의 변화 경향은 전반적으로 다른 지역의 쥐라기 화강암류의 분화 경향과 유사하게 나타나지만, 각 암체의 분화경향이나 화학조성을 살펴볼 때 각 암체의 마그마 근원물질은 서로 다른 것으로 사료된다. 울진화강암류는 연구지역 주변에 분포하는 다른 화강암류와 비교하여 Al2O3의 함량 및 Cr, Co, Ni, Sr, Y, Nb 등 미량원소의 함량에서 뚜렷한 차이를 보인다. 울진화강암류의 지화학적 특징은 높은 Al2O3, Sr 함량과 높은 Sr/Y, La/Yb비를 가지며, 낮은 Y과 Yb함량과 같은 슬랩용융(slab-melting)으로 생성된 아다카이트에서 흔히 관찰되는 지화학적 특성을 나타낸다. 울진화강암류의 주성분원소(SiO2, Al2O3, MgO) 및 미량원소(Sr, Y, La, Yb) 함량 범위는 아다카이트질 화강암의 범주에 포함되며, 지화학적 특성, 지구조환경 및 관입시기가 일본의 북서부 Hida belt에 위치한 Yatsuo심성암체와 유사하다. 연구지역의 암석의 희토류원소 패턴은 경희토류가 중희토류에 비해 부화((La/Yb)CN=10.6-103.4)되어 나타나며, Eu의 부(-)이상을 보이지 않는다. ANK vs. A/CNK과 지구조판별도에서 화강암류의 모마그마는 I-type의 화산호 화강암의 특성을 나타내며, 이자나기(Izanagi)판의 섭입에 의한 압축장 응력이 작용하는 대륙연변부에서 생성된 것으로 해석된다.

The purpose of this study is to analyze the degree of argumentation structure development and factors of development of preservice teachers through SSI related argumentative writings. The study was conducted with 16 preservice teachers that students taking elementary science education theory class in K university located in Chungbuk. The testees wrote six SSI related argumentative writings (once a week), and we examined the degree of argumentation structure development and the change in the recognition of SSI of the preservice teachers by comparing the writings before and after the experiments. The experimental results showed that argumentation structure of the preservice teachers’writings improved and argument level (argument capability) of them also increased as the number of writing was increased. Factors that affect the argumentation structure improvement are mainly argumentation structure education, a number of writings, feedbacks, and subjects related to SSI. In this aspect, the argumentative writing on SSI has the effect of developing scientific sophistication and enhancing the decision-making power of students, and it has positive impacts in science education.

진동화강암체의 아다카이틱한 특성

위수민,김윤지,최선규,박정우,유인창,Wee, Soo-Meen,Kim, Yun-Ji,Choi, Seon-Gyu,Park, Jung-Woo,Ryu, In-Chang 대한자원환경지질학회 2007 자원환경지질 Vol.40 No.2

The eastern extension of the Cordilleran-type orogenic belt continues from southeastern China to the Chukot Peninsula through the Korean Peninsula. The Gyeongsang basin, located in the southeastern part of the Korean Peninsula and the Inner Zone of southwest Japan are characterized by extensive distribution of Cretaceous to Tertiary I-type calc-alkaline series of intrusive rocks. These intrusive rocks are possibly the result of intensive magmatism which occurred in response to the subduction of the Izanagi Plate beneath the northeastern part of the Eurasian Plate. The Jindong granitoids within the Gyeongsang basin are reported to be adakites, whose signatures are high $SiO_2,\;Al_2O_3$, Sr, Sr/Y La/Yb and, low Y and Yb contents. The major and trace element contents of the Jindong granitoids fall well within the adakitic field, whereas other Cretaceous granites in the same basin are plotted in the island arc ADR area in discrimination diagrams. Chondrite normalized REE patterns show generally enriced LREEs (La/Yb)C = 3.6-13.8) and slight negative to flat Eu anomalies. The mean Rb-Sr whole rock isotopic age of the Jindong granitoids is $114.6{\pm}9.1$ Ma with an initial Sr isotope ratio of 0.70457. These values suggest that the magma has mantle signature and intruded into the area during Early Cretaceous. The Jindong granitoids have similar paleogeographical locations, paleotectonic environments and intrusion ages to those of the Shiraishino granodiorites of Kyushu Island and the Tamba granitoids of San'yo belt located on southwestern Japanese arc.

Geochemistry of Precambrian Mafic Dikes in Northern Michigan, U.S.A.: Implications for the Paleo-Tectonic Environment

위수민,Wee, Soo Meen The Korean Society of Economic and Environmental G 1991 자원환경지질 Vol.24 No.4

Petrological and chemical studies of Precambrian dikes in the southern Lake Superior region were conducted with the objects of evaluating magma source and constraining models for the paleo-tectonic environment. Forty-six samples were analyzed for major, trace, and rare earth elements. Chemical data of the studied dikes are typical of continental tholeiites and showing iron-enrichment fractionation trend. With wallrock contamination carefully evaluated, a series of tectonic discriminating methods utilizing immobile trace elements indicate that the source magma was a high-Ti tholeiitic basalt similar to present-day T-type MORB. Effect of chemical contamination from wallrock assimilation accmulates with increasing differentiation. Evolved rocks show LREE enriched patterns and have enhanced levels of LIL elements (e.g., Rb, K, Ba, Th), but low levels of high field strength elements (e.g., Nb, P, Ti) with respect to their neighboring elements. It is suggested from this study that this enrichment possibly due to a combination of a feature inherited from the subcontinental lithosphere and crustal contamination. Geochemical signatures of these rocks are distinctively different from those of arc-related volcanics. Comparisons with chemistries of modern magmas show a pattern of overlap between Within-plate and ocean-floor characteristics, and chemical signatures of these rocks favor a model of intrusion into a crustal environment undergoing lithospheric attenuation.

Interpretation of Subsurface Structure by 2-D Gravity Modeling Study

위수민,도성재,Wee, Soo-Meen,Doh, Seong-Jae The Korean Society of Economic and Environmental G 1991 자원환경지질 Vol.24 No.4

A gravity survey was conducted in the western Marquette district, Michigan, to delineate the subsurface structure and the relationship of the Proterozoic Marquette Range Supergroup rocks (Precambrian X) and Archean basement (Precambrian W) where the Republic, Michigan River, and Marquette troughs join. In order to accomplish these purposes, three hundred and forty gravity stations were established in the area of $380km^2$. Positive anomalies are associated with the Precambria X, metasedimentary sequence which has a higer density with respect to the Precambrian W, basement rocks. The dominant positive gravity anomalies follow the axes of the three troughs which are filled with Precambrian X rocks. Subsurface structure was modelled by using the Talwani method. Gravity model studies indicate that the Marquette trough is asymetrically shaped and steeply dipping at the north edge except in the eastern part of the study area. The interpretive results obtained from two dimensional model studies suggest that the basement structure of the study area is relatively flat, and that the troughs were formed contemporaneously.

위수민,조현준,김선홍,이효녕 경북대학교 과학교육연구소 2009 과학교육연구지 Vol.33 No.1

The purpose of this study was to investigate how the argumentations were affected by the students’ characteristics in the small groups. The level of self-concept and science related attitude were examined to the eleventh grade high school students in Daejeon city, and the twelve students were participated for this study. The participants were divided into homogeneous groups and heterogeneous groups. The argumentations under the condition of the interpretations about the experimental results in each small group were recorded by VCR. The recorded data were transcribed, then argumentation levels from transcripts m each small group were analyzed through Mitchell's parameters of argumentation. The results of this study were that the group which had higher level of both self-concept and science related attitudes achieved higher level of argumentation. Therefore, it is necessary for teachers to induce students to ask questions and present activities appropriately in order for those who have low self concept and science related attitudes to participate in argumentation. 이 연구의 목적은 학생특성에 따른 소집단 구성이 집단 내 논증과정의 수준에 주는 영향이 어떠한지를 알아보는 것이다. 이를 위해 대전시 소재 고등학교 11학년을 대상으로 자아개념과 과학적 태도 검사를 실시하였으며, 검사 결과를 바탕으로 연구에 참여할 12명을 선정한 후, 이들을 이질집단과 동질집단으로 구성하였다. 집단에 주어진 과제를 수행하면서 실험결과에 대한 해석 과정에서 나타나는 학생들의 논증과정을 VCR 자료로 촬영한 후 전사하였다. 전사된 자료는 Mitchell(2001)의 분류틀에 의해 분석되었으며, 그 결과는 다음과 같다. 소그룹 중 자아개념과 과학적 태도 특성이 모두 높은 집단이 나머지 집단보다 논증의 수준이 높았다. 따라서 수업 중 학생들의 논증활동을 증진시키기 위해 자아개념과 과학적 태도가 낮은 학생들이 논증활동에 적극적으로 참여할 수 있도록 적절한 발문 유도와 활동이 제시될 필요가 있다.
