The chemical and kinematic properties of stars in the Galactic halo provide crucial information on the origin of the Galactic halo as well as the assembly history of the Milky Way. In this study, we present metallicity distribution functions (MDFs) in different regions of the Galactic halo as well as the kinematic characteristics in each region. The different MDFs and kinematic properties of stars in investigated regions allow us to associate them with the possible progenitor dwarf galaxies discovered to date; hence the assembly history of the Galactic halo.

History of science (HOS, hereafter) has been considered as a useful tool for achieving a variety of objectives in science lesson. The purpose of this study was to develop three dimensional framework for effectively analyzing HOS content in science textbook. In addition, using this framework, we analyzed HOS content in science textbooks of the 7th curriculum by focusing on the history of Earth science. Developed framework consists of three dimensions; instruction context, role, and type. Each dimension has several sub-domains. The results of textbook analysis revealed that science textbook didn't include diverse HOS materials that are appropriate to three dimensions and its sub-domains of the framework. Based on the results, we proposed that three dimensional framework is an effective tool to develop materials for teaching and learning materials of HOS with multiple coordinations of various contexts and purposes.

Using recently emerging quantitative methods, this article provides a comparative study of the diachronic changes in the narrations of novel, history, and science from the early 18th-century to the 20th-century. To trace the narrative changes in different genres, this article discusses how text-mining methodology can be introduced in literary studies. We compared the traces of narrative in three genres—novel, history, and science—as a pilot study, with the three major grammatical elements of narrative: pronoun, subordinating conjunction, and action verbs in past tense. The results of data-mining show that the use of pronoun and action verb has increased in the genre of novel toward the $20^{th}$ century, while history and science has developed less story-like writing styles.

In order to organize various places for science experience study, this study gathered and analyzed prior research on science experience study and various science experience perated in school. To that end, a total of 162 relevant prior studies of literature published from 2000 to 2016 were collected and 2,201 cases of science experience study conducted in 2015 were collected and analyzed. The place where the science experiential learning was done is divided into three areas of natural ecology, cultural history, facility experiential learning study, and the characteristics of participating subjects are examined. In terms of the number of articles published in the field of science-related experiential learning areas, 83 ecological experience study sites (51.2%), facilities institution experience study sites 56 (34.6%), and cultural history experience study books 23 (14.2%). Through this study, it was found out that research tendency to analyze science - related attitudes became prominent by setting study subjects using natural objects around and learning to play while playing and playing in nature. There was also an analysis by subjects of participation in science related experience learning centers. Cultural history experiential learning field was significantly lower than previous studies. In the lower grades, nature ecological experience learning was mainly performed. Combining the above findings, it can provide implications for the development of science-related experience activities. First, it is necessary to develop a technology-related experience learning center using local community resources. Second, it is necessary to expand the culture and history experience learning center related to science. Third, we need an education support center to support the expansion and operation of such a technology-related cultural history learning center.

Recently, a topic of Archival Science can be said 'paradigm shift'. Therefore, this study aims to establish a relationship between oral record and Archival Science through concept of the archiving 'social memory' related to paradigm shift of Archival Science. In addition, an active role theory by an archivist as main agent of archival oral record management reflecting the characteristics of oral record based on this will be supported. Especially, even if it has already been handled through previous studies, it will be focused on drawing new meaning by applying creative perspective. Main content of this study is as follows. Firstly, discussion will be progressed by establishing the concept of the archiving 'social memory'. This is related to the topic of 'paradigm shift' in the Archival Science. Despite that active research has been conducted among mainly archival researchers overseas, it has not been handled yet in Korea. Therefore, this study aims to determine to organize this part as detail purpose. Secondly, the point will be progressed with a special focus on collecting and planning stages among the stages of records management. A viewpoint of the Archival Science should start from the stage of collecting and planning the previous record of production point of time, and then should be reflected for acknowledging the subsequent stages. Therefore, collecting and planning are the most important, and this is closely connected with a characteristic of oral record which production means collecting. Thirdly, the concept of 'oral record' is established with the viewpoint of the Archival Science. The various documents have been producted through oral interview has been known to many oral history researchers as 'oral source'. It aims to conceptualize them as 'oral record' with the viewpoint of the Archival Science. Fourthly, it is an establishment of meaning why oral history should be handled in the Archival Science. It is necessary to rationalize the purpose and its appropriateness handling oral history in the Archival Science. It should clarify the reason why oral history is important in the Archival Science and what it means. This will help examine the meaning of the recording of 'oral record.' A characteristic of the oral record can be effectively revealed through the recording, and ultimately, it aims to be able to shed new light on the value of oral history and oral record. Finally, it defines the role of archivist in oral history. A point that archivist in oral history is not just an assistant who organizes and preserves oral records collected by researchers will be emphasized and persuaded. In this study, oral history study in the Archival Science which has obtained appropriateness by the theoretical discussion as above should be conducted in a connection with other studies without occupying oral history by the Archival Science and in a direction of the leap of Korean oral history study. If this is possible, it will contribute to development of the Archival Science and of study area expansion, enhancement of the role and potential of archivist, at the same time, eventually it will positively influence on oral history study.

This study was to investigate effects of instruction using the history of science on elementary school students' science learning motivation. Subjects were 48 students of two groups in the 5th Grade in Bucheon City. A Experimental group of 24 was instructed 20 lessons in Unit 1~7 using the history of science for a 11-week period. In this study, the instructional contents were selected by stories about scientists, discoveries or anecdotes about natural phenomena and related learning topics in national science curriculum. And they are presented by writings with pictures, cartoons, PPT materials and a script. Students play various learning activities such as exchanging opinions after reading instructional content, making a book or a newspaper, playing in a drama and representing by picture. A control group of 24 was instructed by traditional teaching methods in same period. To compare difference of instruction effects of the two groups, the score of pre-test and post-test were both estimated by t-test. The results of the study were as follows. Students of experimental group showed statistically a more significant increase in the science learning motivation than control group students (p<.05). Each of attention (A), relevance (R), satisfaction (S) sub-elements of learning motivation were higher in the experimental group and it was showed the instruction using the history of science was effective in improving of science learning motivation.

In this study, we analyzed the learning elements and achievement standards, and explored the appropriateness and hierarchy of content were analyzed related to the nine types of traditional astronomical instruments presented in the traditional science unit of the History of Science course to improve the problematic situation in which students show low selection rates for the History of Science, one of the elective courses in high school science. Based on the results of this analysis, we suggested ways to utilize each astronomical instrument for teaching and learning in science curriculum with different grade bands. Using the results of this study as a starting point, if a follow-up study that develops specific achievement standards or inquiry activities related to traditional astronomical instruments can be conducted, students' awareness of Korean traditional science culture can be improved, and furthermore it is expected to increase the student's selection rate for the History of Science course.
