The purpose of this study is to analyze the science history materials presented in middle school 'Science' textbook according to the 2015 revised curriculum. The subjects of this study were 14 middle school 'Science' textbooks. The analysis used the three-dimensional framework. The results of analysis show that the number of science history materials presented in textbooks tends to increase as the grade goes up. It was also found that science history materials were presented in a specific unit for each grade. The three-dimensional analysis of science history materials showed that conceptual-fundamental-discovery/device types were most commonly presented in all grades. At the instruction context level, the conceptual context was the most common, and the basic role was the main at the role level. The discovery/device type was the most common type of presentation. The results of the study show that the science history materials presented in science textbooks were concentrated in some areas. Also, the instruction context and role were concentrated in some factors in terms. This suggests that various science history materials need to be developed in the future. It is also necessary to explore concrete methods to ensure that science history materials presented in textbooks can be used in various roles in different contexts.

Researchers have observed one student who had difficulty in formulating a division equation. In the context of determination of a unit rate problem based on one student's case and previous research, we tried to examine in detail how students expressed the division formula, how to select the dividend and the divisor, and how they learned about those. First, a questionnaire was developed to analyze student's reactions and applied to the research participants. Interviews were conducted to discover how the participants choose the dividends and divisors derived from their cognitive characteristics corresponding to their selection method. The research exposed that the majority of the participants had difficulty in deciding the dividends and divisors. Moreover, the research indicated information that teaching methods need to be reformed. Finally, we obtained suggestions to place emphasis on how to decide a dividend and a divisor, why they made such selection and what the equation means. We proposed a learning method for the research above.

The purpose of this study is to identify the context and pattern of Korea's self-sufficiency program based on the experiences of self-sufficiency program practitioner. To this end, this study applied the context-pattern analysis method, which was known as one of the qualitative research approaches, to provide proper and effective evaluations of self-sufficiency program. The analysis shows that the context of the self-sufficiency program consists of such sub-contextual components as 'market economy', 'social service system', 'self-sufficiency system', 'self-sufficiency program', 'self-sufficiency program participant', 'procedural experiences of the program', 'outcomes of self-sufficiency program', and 'meaning of the self-sufficiency program'. Furthermore, such patterns as 'decreased vitality of self-sufficiency system', 'service flow', 'journey to the self-sufficiency', and 'sequences to small success', were also presented. Based on these findings, this study suggests policy and practice implications, and subsequent related research topics.

The fourth industrial revolution and creative economy are in the center of today's economic environments. In this context, venture companies make great efforts in achieving innovative capability for sustainable growth. Especially, in order to create the innovative capability or innovation performance, they are very much interested in obtaining such characteristics of organizational ambidexterity as exploration and exploitation. Thus, this study aims to study the organizational contextual ambidexterity as a key factor to create SMEs' performance and to conduct an empirical research with the data collected from domestic SMEs in order to find the antecedent and consequence of this ambidexterity. In so doing, we selected as an antecedent of contextual ambidexterity quality management practice, which is an innovative method of enterprise innovation and enterprise level, innovation performance (radical and incremental Innovation performance) as a consequence and ran a series of regression analyses. As a result, quality management practices such as quality circle activities have had positive effect on organizational ambidexterity, that is, exploration and exploration, and contextual ambidexterity has affected positively on innovation performance. It is also found that the contextual ambidexterity plays a full mediating role in the relationship between quality management practices and innovation performance. The results of this study suggest that contextual ambidexterity is essential to achieving organizational innovation performance and quality management activities such as quality circle should be preceded in order to stimulate or stimulate contextual ambidexterity.

디지털콘텐츠 산업분류체계를 비롯한 기존 방식으로는 현재의 디지털콘텐츠를 통찰력 있게 보기 힘듭니다. 이는 디지털콘텐츠 일반에 대한 인식의 틀이 부실한 탓입니다. 넓은 의미의 텍스트에서, 시점(視點)은 인식의 틀입니다. 문학과 미술, 영화와 관련된 콘텐츠 하부영역에서는 시점 연구가 체계적으로 이루어져 왔습니다. 이러한 시점 연구결과들을 통합하고 정리하여 디지털콘텐츠에 접목시켰습니다. 연구자는 콘텐츠와 그것의 사용자에 대한 관계를 두가지 기준으로 구분하였습니다. 하나는 콘텐츠와 사용자 자아인 페르소나 사이에 성립되는 '맥락인지적시점(ContextualView)'이고 나머지 하나는 콘텐츠를 비추는 눈인 '시각적시점(CameraView)'입니다. 맥락인지적시점은다시 '인물', '상대', '관객'으로 구분하였고 시각적시점은 '일인칭', '이인칭', '삼인칭'으로구분하였습니다. 그리고 이를 씨실과 날실로 연결하여 'CCmatrix'라 하였습니다. 그리고 월드 오브워크래프트를 'CCmatrix'로 분석하고 캐릭터 수준별로 일정한 패턴을 발견하였습니다. 또 다른 활용으로는 디지털콘텐츠의 시점역사를 정리하고 활용가능성을 보였습니다.

In this study, we observed the characteristics of students' small group discussions concerning the four friction problems. Participants in this study were 22 students of upper-level mechanics course and their small group discussions have been transcribed. As a result, we found that the phenomenon in this study is well defined by 'common context.' The process of formation of the common context was explicitly observed when students discussed about the identification of the problem situation (especially the movement of A in the second problem), the nature of friction and various forces, inertial frame, and noninertial reference frame. Meanwhile, the formation of common context was tacit when students thought they already had a common context. For example, students did not discuss about the friction rule itself because they had confidence about the knowledge. We also found that the presence of the questioner, receiver, and the other opinion were important for positive group discussions. The result of this study would be meaningful because it analyzed how the theme affects the group discussion beyond the limit of previous studies of just analyzing the form or pattern of discourse.

The purpose of this study was to compare rock descriptors used by students in two different task contexts and to suggest the characteristics of a task suitable for learning of rocks. Twenty-four 3^rd grade students were given descriptive and inferential tasks about three types of sedimentary rocks, and the rock descriptors used by the students were analyzed from a resources-based view (RBV) about students' conceptions. The result showed that the number of students using everyday descriptors to describe properties of the rocks and the frequency of using the everyday descriptors decreased in the inferential task. It was also revealed that the students using disciplinarily more appropriate descriptors were more likely to infer the process of rock formation in scientifically valid ways. By contrast, student inferences lacking scientific validity were mostly those that used everyday descriptors to express properties of the rocks. Based on these findings, it was concluded that inferential tasks would be suitable for student learning of rocks which is to be authentic to the essential features of earth science practices.

Analogy, a plausible reasoning on the basis of similarity, is one of the thinking strategy for concept formation, problem solving, and new discovery in many disciplines. Statistics educators argue that analogy can be used as an useful thinking strategy in statistics as well. This study investigated the characteristics of students' analogical thinking in statistics. The mathematically gifted were asked to construct similar problems to a base problem which is a statistical problem having a statistical context. From the analysis of the problems, students' new problems were classified into five types on the basis of the preservation of the statistical context and that of the basic structure of the base problem. From the result, researchers provide some implications. In statistics, the problems, which failed to preserve the statistical context of base problem, have no meaning in statistics. However, the problems which preserved the statistical context can give possibilities for reconceptualization of the statistical concept even though the basic structure of the problem were changed.

This study intended to examine the nature of image which uses the network as the medium in the context of 'post-internet art' and categorize and analyze the cases of applications within art images. In the post-internet art which embraces the background of Web 2.0 and extended digital and network environment, image is transformed and re-mediated into various formats beyond fixed forms. Hito Steyerl defined the image, copied, downloaded, and reedited digitally in low quality as 'poor image.' Young artists, the digital native generation, capture and re-contextualize the changed network environment and depict it in various images. In this context, the application of image in post-internet art can be categorized and analyzed into the 'Image Collected as Material' produced by collecting and recomposing images found in social media, operating system, and website, 'Image Processed through Work' which is newly processed and re-contextualized by using editing programs, and 'Combined Digital-Reality Image' which represents the section of the digital society as the film and image that combine virtuality and reality.

이 글은 싱가포르에 거주하는 한국인 기혼 여성을 대상으로 영구 이민이 아닌 체류이주 맥락에서 일과 가족 양립 문제의 어려움과 그 대응전략을 살펴보는 탐색적 질적 연구이다. 지난 십여 년간 꾸준히 증가한 해외 거주 한국인 중장기 체류자(sojourner)의 수는 2007년 기준으로 1백5십만 명을 넘어섰다. 그 중 상당수는 한국계 기업 파견 직원('주재원')이나 비한국계 다국적기업 혹은 현지기업 종사 이주자로 파악된다. 고학력 전문 기술직 이주자(highly educated professional/high skilled migrant)에 대한 연구가 매우 드문 한국의 맥락에서, 전문 기술직 체류자 중심으로 이주 한국인 사회가 구성된 싱가포르는 전문 기술직 이주자의 일과 가족 양립 문제뿐만 아니라, 체류자 사회(expatriate community) 전반적인 연구의 중요한 대상지로서의 장점이 크다. 연구 질문은 다음과 같다. 체류자로서 외국에서 일하며 살아가는 어려움은 무엇인가? 특히, 이러한 맥락에서 기혼 여성의 일은 어떠한 의미를 지니며 어떠한 대응전략을 마련하는가? 이 연구는 2006년부터 2007년 사이 수행한 전일제 전문직종 종사자, 파트타임 종사자, 전업주부 등 자녀를 둔 26명의 기혼 여성에 대한 심층면접 자료에 근거하여, 아내이자 어머니로서의 일과 가족 양립에 관한 체험적 경험(lived experience)을 탐색적으로 파악하였다. 연구결과는 다음과 같다. 전일제 전문직 종사자의 경우 가정친화적 근무 환경을 갖춘 직장으로의 이직, 남편과의 야간근무 조정 등을 포함한 다양한 전략들을 채택하였다. 파트타임 종사자의 경우 과거 한국에서 전일제 근무를 경험하고 현재 상대적으로 경제적 여유가 있는 경우는 전일제 근무로부터 벗어나는 '일시적 행복감'을 느끼는 경우가 많았다. 비교적 경제적 여유가 없는 경우, 어머니 역할 부족을 발견하는 계기가 되기도 했다. 이러한 어머니로서의 역할은 친지를 비롯한 한국어 구사를 할 수 있는 가사 보조 네트워크가 결핍된 체류이주 맥락에서 일하며 살아가는 것에서 있어, 비교적 쉽고 저렴하게 가사노동자를 고용하더라도, 어머니로서의 역할을 보조하는 데 큰 도움이 되지 않는다는 생각을 확인시켜준다.
