  • In this study, various scientific viewpoints of 'motion of objects' were analyzed from the Aristoteles age to the Newton age. From the analysis, a questionnaire was developed which was including causes of motion, forms of motion, and preservation quantity of movement. The conceptions of pre-service science teachers were researched by the questionnaire developed in this study based on the science historical viewpoints. The subjects were twenty sophomore students of physic education major and thirty four of other science education major who majored common science education also in a college. Most of the pre-service teachers of physical education major had inertia and Newton's force conception related to the question situations of 'causes of motion' and 'forms of motion'. But a lot of the pre-service teachers of physic education major and other science education major had viewpoints of Descartes or Huygens related to the question situation of 'preservation quantity of movement'. Only few pre-service teachers regardless of major had Newton's viewpoint which represented in current Korean science curriculum for secondary school.

  • This study aimed to analyze the historical evolution of general ideas concerning the particles that represent matter properties and matter changes divided into physical change and chemical change. In the science historical viewpoint, the general ideas of the base that represent matter properties has been variously revised the 5types. The definition of the matter change have also changed the 3 types. From the analysis of the definitions in secondary school science textbooks and general chemistry textbooks, we found that a lot of confusion of eras in the contents that define the concepts. Sometimes, the definition presented in one textbook was contradictory to the definitions in other textbooks. This tendency has been sustained in the textbooks from the 4th to 7th science curriculum.

  • In this research, a questionnaire was developed to investigate high school students' viewpoints, originating from science history, on 'motion of on object', the subjects were seventy- five 10th grade students and sixty-five 11th grade students. Results found that the highest percentage among the types of 10th grade students' thoughts was related to the Middle Ages 'Impetus' viewpoints. Percentages of 11th grade students' thoughts were highest for Middle Ages and Newton views. These results provided proof that the development of student thoughts' based on science history' are consistent with school year. Furthermore, student thought regarding 'object motion' under the conditions of no force, vacuum, or air under a weightless stage were related to progressive viewpoints on science history. However, the percentage of thoughts related to earlier viewpoints were considerable. Student thoughts on parabolic motion, circle motion, and conservation amount of motion were found to be highly significant in similarity to the viewpoints of Galilei, Descartes, and Huygens; view cultivated before Newton. Consequently, this study determined that educational efficiency could be raised by providing historically more progressive views to cope with conflictory student thoughts-thoughts related to past views in science history.

  • In this study, we identified the conceptions of heat and temperature on a basis of the science history, and analyzed the explanation types in elementary, and secondary school science textbooks. From these data, we tried to discover the cause of students' misconceptions. The results revealed that the explanation types of the textbooks don't include modem sight. Different conceptions developed in different era mixed in the textbooks. We can infer that students who learn heat and temperature concept by the textbooks could have misconceptions because of the above problems.

  • Most student misconceptions about evolution are similar to misconceptions and disputes which early scientists had in science history. The aim of this study was to analyze student evolution conceptions based on science history, there by revealing for effectively teaching strategies on evolution. A test was developed according to Lee's three dimensional framework (2004) on evolution concept changes. Lee's framework had been constructed according to 4 stages of evolution concept changes in history in three-dimensional aspects such as mechanism, time, and subject: before Lamarck (stage 1), Lamarck (stage 2), Darwin (stage 3), and after Darwin (stage 4). Major results were as follows. First, the evolution conceptions of students appeared fixed to stage 2 regardless of grade. Moreover, students usually possessed Lamarckian thought and did not show consistency in evolution concepts among the three dimensional aspects of mechanism, time, and subject. Therefore, students were found to apply different conceptions of evolution to each different situation.

  • The purpose of this study was to survey the secondary science teachers' viewpoints of basic particles conceptions addressed in science course. The first content of this study was to analyze the secondary science teachers conceptions related to basic particles founded on scientific history viewpoints. The second content was to investigate their understanding of relations between atom, element, and molecule concepts. The third content was to search the factors influenced on basic particles conceptions of science teachers. For this study, 96 secondary science teachers were selected. The data of this study were collected through a questionnaire developed for this study and were analysed using the method of constant comparative analysis. The results showed that their viewpoints towards basic particles were similar to each other regardless of their majors and their conceptions belonged to the past viewpoints. The teachers lacked linking understand among basic particles conceptions because they applied different viewpoints on different problems. Most of the teachers were influenced on science textbooks, guidebooks for teachers, and reference books to form confusing viewpoints of basic particles.

  • This study analyzes Korean childcare policy from a caring democracy perspective by using the normative policy analysis method. In the midst of emergent new social risks engendered by low fertility and aging population, feminist scholars proposed a transformative paradigm shift from economic growth to caring oriented development on a macro scale but researches on how this grand principle can be reflected into each policy have hardly been discussed. Thus, this study intends to contribute to such policy-driven discussion by analysing childcare policy on the basis of three normative values of freedom, equality and justice re-interpreted by caring democracy theory. Following are key findings. First, childcare policy does not guarantee public value and social solidarity due to the limitations of free choice from the perspective of freedom. Secondly, gender and class stratification has been worsened in a multiple and more complicated way by adding generational and racial dimensions to the existing gender inequality and vicious circulation of private care is observed from equality perspective. Thirdly, structural inequality aggravated injustice previously accumulated in the past rather than providing flat ground by adjustment.

  • 한국전쟁기 북한 소설에 대한 북한의 문학사적 평가는 남한의 문학사와 비교할 경우 매우 큰 차이를 보여주고 있다. 남한에서 나온 대부분의 문학사에서는 한국전쟁기 남한 소설에 대해 대체로 부정적인 평가를 내리고 있으나, 북한에서 나온 문학사의 경우에는 한국전쟁기 북한 소설을 매우 긍정적으로 평가하고 있는 것이다. 물론 이러한 평가는 남북한 문학사의 문학에 대한 관점의 차이에서 비롯되었다고 할 수 있다. 그러나 북한에서 나온 북한문학사의 경우에는 정치적 목적에 따라 작품을 왜곡하여 평가하고 있는 경우가 많으므로 사실에 대한 면밀한 검토가 필요하다. 이태준, 김남천, 임화 등 남로당 계열 작가의 작품에 대한 북문학사의 평가는 특히 그러한데, 남한에서 이루어진 북한문학에 대한 논의들은 이러한 사실을 지적하면서 한국전쟁기 문학에 대한 실증적인 자료조사와 과학적 연구의 필요성을 제기 하고 있다.

  • This study aims to examine the prospecting view of future society from a critical perspective, and to explore the direction of home economics education that can lead to transformation of future society from Habermas's critical theory. For this, Habermas's critical theory was understood, and the direction was explored in which field should act to guide future society when home economics education took a critical science perspective. Direction for praxis of home economics education was explored in both lifeworld and system area of society based on the critical theory that individuals, families and society are mutually beneficial and continue through interactions. The praxis of home economics education from a critical science perspective has been found through examples of IFHE's advocacy and policy participation activities. In conclusion, it supported the reason that home economics education as a critical science should form a social, political and economic system as well as lifeworld with valued human conditions and practice professional activities in academic, daily life and societal areas which will lead to the critical and participatory changes in individual and family life.

  • This study is for better understanding about the process of students' conceptual change. As a starting point, it is assumed that the process of students' conceptual change can be viewed as the process of the successive refinement and articulation of students' conceptual framework. Based on the theoretical review of conceptual change literature, various processes, which can be involved in the above assumed process, can be found. And also, by analyzing the process of development of scientific knowledge about Planck's blackbody radiation law and Bohr's atom, six types of processes of refinement and articulation of scientific knowledge can be found. It is hoped that these theoretical discussions can guide the direction for obtaining and interpreting the students' real responses during the process of conceptual change.
