  • 과학교육에서 효과적인 과학 수업을 위하여 과학사 도입의 중요성이 계속 강조되어 왔다. 이에 따라 과학 교과서에는 많은 과학사 자료가 사용되고 있다. 하지만 과학 교과서에 사용된 과학사 자료가 어떤 유형과 맥락에서 어떠한 역할을 하고 있는 지에 대한 면밀한 분석은 이루어지지 못한 실정이다. 이에 본 연구에서는 선행 연구와 관련 문헌 분석을 통해 과학 교과서에 사용된 과학사 자료를 분석하기 위한 3차원 틀을 개발하고, 이를 제 7차 교육과정의 과학 교과서 지구과학 내용을 대상으로 적용하였다. 개발된 분석틀은 수업맥락, 역할, 제시유형의 3개 차원으로 구성된다. 수업맥락 차원은 흥미, 사회-문화적, 인식론적, 개념적 맥락의 4가지 영역으로 세분되며, 제시유형 차원은 에피소드/일화, 발견/고안, 선형적인 발전, 역사적 실험의 4가지 영역으로 세분된다. 역할 차원은 기본적, 보충적, 탐구적의 3가지 영역으로 세분된다. 개발된 3차원 분석틀을 적용하여 과학 교과서의 지구과학사 자료들을 분석한 결과, 수업맥락 차원에서는 개념적 맥락의 과학사 자료가 모든 학년별 과학 교과서에서 가장 많았다. 역할 차원에서는 기본적 역할이 압도적으로 많았으며, 탐구적 역할의 경우에는 매우 적었다. 제시유형 차원에서는 발견/고안과 선형적인 발전 유형이 대부분이었고, 에피소드/일화 유형의 자료는 주로 흥미 맥락과 연계되어 극히 일부만 사용되고 있었다. 3차원 각 영역들을 48개의 조합으로 분석한 결과, '개념적 수업맥락-기본적 역할-발견/고안 유형'과 '개념적 수업맥락-기본적 역할-선형적 발전 유형' 2개 조합에 집중되었으며, 나머지 조합들의 빈도는 매우 낮았다. 전체적으로 3차원 분석틀 각 영역에 부합하는 과학사 자료가 과학 교과서에 다양하게 포함되지 못하고 일부 영역에만 집중되는 것으로 나타났으며, 이러한 연구 결과는 앞으로 다양한 수업맥락, 역할, 그리고 유형으로 과학사 자료들이 개발될 필요가 있음을 시사한다.

  • In this study, we classified word problems related to real life presented in elementary mathematics textbooks into five types of context problems(location, story, project, scrap, theme) suggested by Freudenthal(1991), and applied context problems to mathematics class to analyze the influence on students' mathematical belief and attitude. Also, we examined the types of context problems preferred according to academic performance and the reasons of preference within a group experiencing context problems. The results of the study are as follows. First, almost lessons in the mathematics textbook presents word problems related to real life, but the presenting method is inclined to a story type. Also, the problems with a story type are presented fragmentarily. Therefore, although these word problems are familiar to the students, they don't include contextual meanings and cannot induce enough mathematical motives and interests. Second, a lesson using context problems give a positive influence on their mathematics belief and attitude. It is also expected to give a positive influence on students' mathematics learning in the long run. Third, the preferred types of context problems and the reasons of preference are different according to the level of academic performance within the experimental group.

  • In this paper, we analyzed the types of tasks presented in the 'Probability and Statistics' textbooks and how the cognitive competences required to perform the tasks provide students with opportunity-to-learn. To this end, the analysis of the 9 books of the 'Probability and Statistics' test textbooks according to the 2015 revised mathematics curriculum showed that the context-based tasks(CF type, RE type) ranged from 67.5% to 78.0% of the total number of tasks in each textbook, but the ratio of relevant and essential tasks related to real life is from 0.4% to 2.0%, it was found that most of the context-based tasks presented in the textbooks were disguised as real life materials. The cognitive competences of context-based tasks ranged from 29.6% to 50.0% in reproduction category, from 33.8% to 54.3% in connection category, and from 8.8% to 20.0% in reflection category. As a result, there was not enough opportunity-to-learn for students to experience reflective cognitive processes.

  • This study investigates human-robot interactions in a museum environment. Unlike robots in movies, robots in real life do not have 'personality,' but instead have a specific purpose and function. This research is primarily about the assignment of specific and appropriate personalities to robots in different contexts. Methods by which a definite personality can be imparted on a robot are discussed in this research. Previous research has addressed attempts to assign a robot personality based on the task context. However, the discussion of robot personality is incomplete. Therefore, we assumed that a robot's character was dependent on the characteristics of its location of use. We planned a $2{\times}2$ comparison of various robot personalities, i.e., introverted or extroverted paired with either a traditional museum or a process-oriented experiential experience. Based on Schmitt's (1999) strategic experiential modules, experiential factors were derived for each set of conditions. To achieve the objectives of the research, theoretical and empirical research were conducted simultaneously. The software JMP 9 was used to verify the research model and hypotheses.

  • The purpose of this study investigate the differences in children's reading abilities of environmental print according to children's age and types of parental literacy interaction. The subjects comprised 111 illiterate children, 3 to 4 years of age, and their mothers. The Children's Reading Abilities of Environmental Print Scale (CRAEPS), Parent's Literacy Interaction Rating Scale (PLIRS) as developed by Son (2012) were used in this study. The collected data are analyzed by means of descriptive analysis, K-mean cluster analysis, Correlations, and two-way ANOVA. The results of this study are as follows : Illiterate Korean children, aged 3 to 4 years, can read environmental print which are familiar to them, and an 'open interaction style' plays an important role in developing the child's reading ability of environmental print. Therefore, in order to develop child literacy, it is necessary to research, not only teaching methods for using environmental print in the home, child care centers, and in kindergarten, but also parent education programs regarding the importance of the mother's literacy interaction style.

  • Visual communication based on socio-cultural context, such as emoticons on social media, is increasing. Therefore, it is necessary to study the visual expression of metonymy as a means to correctly understand the communication method in the age of visual culture. The purpose of this study is to explore how metonymy is visualized within a cultural context. Specifically, , a typical underlying phenomenon of metonymy expression, and the expression principles of various reproduced through it are identified by pairing them with the cultural context. Based on context theory, which is a representative discourse in the social science field, emoticons from in high context and emoticons in in low context were selected and compared as case study subjects. The major findings are: First, a visual application model of metonymy was proposed regarding the process through which metonymy is reproduced as a visual result. Second, the types of metonymy and their salience attribute applied to the emoticon expression method was identified in detail. Third, based on the contextual theory, how the characteristics of high-context visual metonymy differ from that of low-context visual metonymy were presented. In the future, the results of this study can be used as a criterion for judging the local acceptability and local suitability of design results in the design development process that requires the use of localization strategies.

  • This study tried to verify the context effect in cosmetics advertisements by examining the cosmetics advertisement effect according to whether the brand image and the model image matched, and whether the brand image and the advertisement copy were harmoniously perceived. To this end, data were collected using the brand value type (3) × advertisement copy type (3) factorial design. The results are as follows. First, as a result of confirming the advertising effect according to the matching of the cosmetic brand image and the model image, it was found that both the advertising attitude and purchase intention were significantly high when the model image and the brand image matched. Second, it was confirmed whether there was a difference in the advertisement effect according to whether the cosmetic brand image and copy type matched. As a result, consumers who perceived that the cosmetic brand image and copy type matched had significantly higher advertising attitudes and purchase intentions than consumers who perceived that the copy type did not match. It is expected that it will provide validity as to whether the copy strategy should be established by incorporating the context effect when setting up a copy strategy for cosmetics advertisements in the future.

  • 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.
