  • The purpose of this study was to analyze the understanding of the sighting and hearing elementary school students have through drawing. For this purpose, we conducted a questionnaire survey of 602 elementary school students. The questionnaire was composed with open-ended question developed by West et al.(2008). This questionnaire was presented only appearance of face. And let them express the sensory pathway by drawing and writing. The students' responses for questionnaire were classified by 5 levels. Inner-researcher consistency was 0.89, inter-researcher consistency was 0.83. The data analyzed were ${\chi}^2$ by using SPSS. The result of this study were as following: First, elementary school students have misconception of sighting and hearing. There were no difference among the grade. In spite of becoming upper grade, students have still misconception. Second, scientific concept that male students have were significantly more than female. Third, the concepts of the anatomically organs are more exposed in real-life situations, students known better. Within these results, it would be used for developing teaching-learning strategies which can use misconceptions students have.

  • The purposes of this study were grasping the degree of students' understanding for course contents through the concept mapping strategy as meaningful learning in science and measuring the effect for change of conception and changing the misconception. The results of the study were as follows: 1. Before the lesson, only 10.7% of students had scientific conception of molecular motion. Other students had various kinds of misconceptions. 2. The extent of concept formation after lesson through the using concept mapping strategy was tested. As a result, compared with the controlled group, the experimental group showed higher extent of sound concept formation (statistical significance level 0.05). 3. The differences between the experimental group and the control group were analyzed into quantitative and qualitative points of view. The results of the comparison showed that the maps of the students were well configured in the categories of the relationship, the hierarchy and the examples; while students showed lower abilities in the category of the cross-links. 4. The student's attitudes to ward concept mapping was positive. Most of the students answered that teaching strategy of concept mapping benefits them in meaningful learning outcomes.

  • This study researched the concepts that elementary school students have after having learned volcano and earthquake. The reacher collected and adjusted the journals related to this study, and sampled the concepts included in Chap. One "Moving Earth", the first term of the elementary school sixth year. The students' descriptive responses were analyzed after subjective questions on the basis of above were developed and put into. After the contents described in the answer sheets were categorized by key words and the types of concept were made out by qualitative analysis, it was showed what was differences between the sexual, regional and achievement levels. The results of this study were as follows; first, though the types of concept about volcano and earthquake were found variably, it was showed that wrong preconception was not corrected, especially the exact understanding about terms not attained to, which led to the trouble in conceptual readjustment of students. Second, though the response rate about the types of scientific concept was found high that volcano was made out of explosion and eruption of magma and lava, there were also children who described not the interior factor of globe but the surface factor. Third, according to the results divided into the interior factor of globe and the surface factor and analyzed about earthquake, there were a great number of children who responded as the surface factor though most of the students responded to the interior factor of globe. Fourth, through some types of concept, it was found that the formation of concept was much influenced by experience of children's life, curriculum, and the method of study. Fifth, In the most test question, the scientific concept was found that boys were higher than girls in the distinction of sex, the children of cities than those of town and island, and the upper group than the lower group in the achievement levels.

  • Some would argue that the search for the origin and treatment of this disease will continue over the next quarter century in much the same manner as it has in the recent past, by adding further layers of complexity to a scientific literature that is already complex almost beyond measure. But we anticipate otherwise: those researching the cancer problem will be practicing a dramatically different type of science than we have experienced over the past 25 years. Surely much of this change will be apparent at the technical level. But ultimately, the more fundamental change will be conceptual.

  • 이 연구에서는 불일치 사례의 맥락이 인지 갈등 전략을 이용한 개념 변화 과정에 미치는 영향을 인지 갈등, 상황 흥미, 주의집중, 노력, 개념 이해도 등의 인지적․정의적 변인 측면에서 조사하였다. 중학교 1학년 536명을 대상으로 선개념 검사를 실시했다. 이후 불일치 사례에 대한 반응 검사와 상황 흥미 검사를 실시했다. 과학적 맥락이나 일상적 맥락의 불일치 사례는 학생들에게 무작위로 제시되었다. 밀도 개념 학습 후, 주의집중과 노력, 개념 이해도 검사를 실시했다. 목표 오개념을 지닌 194명의 응답을 분석한 결과, 과학적 맥락의 불일치 사례가 일상적 맥락의 불일치 사례보다 더 높은 인지 갈등을 유발하는 것으로 나타났다. 그러나 불일치 사례의 맥락은 상황 흥미, 주의집중, 노력, 개념 이해도와 유의미한 상관관계를 보이지 않았다. 경로 분석 결과, 불일치 사례의 맥락은 인지갈등에 직접적으로 영향을 주고, 인지 갈등을 매개로 개념 이해도에는 간접적인 영향을 주는 것으로 나타났다.

  • This paper proposes an approach in Southeast Asian studies using a post-colonial framework in the study of post-colonial Southeast Asia. This framework is based on the sociology of knowledge that analyzes the dialectical relationship between science, ideology, and discourse. Post-colonial studies is critical of the concept of universality in science and posits that a scientific statement of a society cannot stand alone, but is made by authors themselves who produce, use, and claim the so-called scientific statement. Several concepts in post-colonial theories can be used to develop area studies, i.e. colonial discourse, subaltern, mimicry, and hybridity. Therefore, this study also explores these concepts to develop a more comprehensive understanding of Southeast Asian culture. The development of post-colonial theories can be used to respond to the hegemony of social theories from Europe and the United States. The main contribution of area studies in the field of the social sciences and humanities is in revealing the hidden interests behind the universal social sciences.

  • 이 연구의 목적은 고등학생들의 광물과 암석에 대한 개념 이해의 특징을 알아보는 것이다. 연구 목적을 위하여, 광물과 암석에 대한 개념 질문지를 개발하였다 질문지는 4개의 영역으로 총 12문제로 구성되어 있었다. 고등학교 10학년 학생 93명, 11학년 학생 119명을 대상으로 자료를 수집하였다. 수집된 자료의 분석을 통해 고등학생들의 광물과 암석에 대한 이해 수준 및 특징은 다음과 같이 나타났다. 전체적으로 고등학생들은 절반정도의 이해 수준을 보였으며, 10학년 학생은 화성암 영역에서, 11학년 학생들은 암석 영역에서 평균보다 약간 낮은 이해 수준을 보였으나, 광물의 녹는점과 관련된 특정 개념에서 매우 낮은 이해를 나타냈다. 둘째, 10학년과 11학년 학생의 이해수준은 대체로 비슷하여 과학적 개념 형성 비율이 유사함을 나타냈으나, 몇몇 문항에 대해서는 학년이 올라감에 따라 과학적 개념 형성 비율이 증가한 경우도 있었다. 그러나 학년이 올라갔음에도 통계적으로 유의하지는 않았지만, 현무암의 표면적 특징을 묻는 문항에서 오히려 비과학적 개념의 빈도가 줄어들지 않고 늘어나는 경향을 보인 것도 있었다. 셋째, 학생들의 과학적 개념 형성에 지구과학 교과에서 배운 개념뿐만 아니라 주변 과학교과에서 배운 개념이 광물과 암석 개념 형성에 도움을 준 것도 있었지만 오히려 방해된 것도 있었다. 이 결과를 통해 학생들에게 지구과학 교과에서 사용되는 특징적인 용어들에 대한 교육을 할 경우 타 교과에서 사용되는 의미와는 별도로 이해되어야 한다는 것을 염두에 두고 가르칠 필요성이 제시되었다.
