  • The 'core concepts', 'generalized knowledge', and 'skills' are newly introduced in the 'contents system' of the 2015 revised national curriculum, and the 'skills' are not clearly defined in the science curriculum. There is a problem of uniformly presenting 'skills' in all 'areas' of science subjects. In this study, it was intended that the teachers' clear understanding of the 'skills' and the philosophy of the revised curriculum would be applied to the school classrooms through the critical problem recognition and consideration of 'skills' newly introduced in the 'contents system' of the 2105 revised science curriculum. First, we reviewed 'science and engineering practice' in the NGSS, which was a reference to the introduction to the curriculum, and identified the problems of 'skills' presented in the science curriculum. It also analyzed critically by comparing 'skills' and 'practices' with other subjects and previous curriculum. Based on this critical analysis, we suggested the following. First, introduce 'skills' items that can implement scientific key competencies, and clearly define each item. Second, present 'skills' that are appropriate according to the subject, 'area', 'core concept', and grade(group) and describe in detail how to apply 'skills' and, third, present 'skills' directly in 'achievement standards'.

  • The present study tested the hypothesis that adolescents' performance on scientific reasoning tasks and their ability to change theoretical concepts during instruction are mediated by prefrontal-cognitive functions, such as planning and inhibiting. Subjects sampled from four Korean secondary schools were administered a test of scientific reasoning ability and tests of the prefrontal lobe functions. A series of lessons on theoretical concepts was also administered. Subjects' performance on the test of scientific reasoning and pre- to posttest gains in the concept test were used as dependent variables. This study found that students' planning and inhibiting abilities were highly correlated with and they significantly predicted their scientific reasoning ability and conceptual gains. Further, principal component analysis showed prefrontal lobe functions were categorized into two main components. Component 1, which was loaded by planning and working memory functions, was termed as the representing process. Component 2, which was loaded primarily by the inhibiting functions, was termed as the inhibiting process. Scientific reasoning and conceptual change were also linked to these two components, indicating that these cognitive processes are mediated by both representing and inhibiting processes.

  • 과학상은 과학자 사회를 유지하는 중요한 기제인 보상체계의 한 요소로 과학사회학에서 많은 연구가 이루어졌다. 전통적으로 보상의 기능은 과학적 업적에 대한 인정의 배분으로 간주되었다. 그러나 머튼 이후 여러 학자들은 과학상을 비롯한 보상이 당대의 인지적 규범에 순응하게 만드는 사회적 통제의 과정이기도 하다는 주장을 제기했다. 이 논문은 우리나라 과학상의 역사적 변천과정과 그 특성에 대한 분석을 통해 과학상이 인정의 적절한 배분으로 과학자 사회 내에서 작동했는지 살펴본다. 분석을 통해 드러난 우리나라 과학상의 특성은 다음과 같이 요약된다. 첫째, 우리나라 과학상은 정부에 의해 주도되었고, 상의 가시성의 원천은 정부 또는 국가에서 나온다. 둘째, 과학상은 과학자 사회 내부의 인정 배분이라는 전통적 기능보다 정부의 정책 목표달성을 위한 통제 방식으로 기능하는 경향이 있다. 셋째, 최근 과학상은 연구비와 결합되면서 과학엘리트를 형성하고 그 구조를 강화시키는 하나의 통로가 되고 있다.

  • This study aims to explore, using both quantitative and qualitative data analyzing the structural relationship between creative process and product, the types of elementary students' scientific creativity. For this, 105 fifth-graders responded to a scientific creativity test that assesses creative process and product, and four students who scored the highest were interviewed. In the interview, they were asked about the cognitive process they used in generating the creative product. Then, correlation analysis and structural equation modeling were used, along with the interview data, to type the students. The main findings of the study are as follows. First, the structural equation modeling of creative process and product gave satisfactory results in absolute and incremental fit indexes. Second, among the three components of creative process - knowledge, inquiry skill-observation, and creative thinking skills -, only creative thinking skills had significant effects on creative product. Third, divergent thinking skills had the strongest correlation with the creative product, followed by convergent thinking skills. Associational thinking skills did not have significant correlation. Fourth, elementary students' scientific creativity could be categorized into Creative Type, Useful Type, Original Type, and Non-creative Type, based on their creative product. The Non-creative Type could be further classified into Common Type, Repetitive Type, Non-response Type, Irrelevant Type, and Abstract Type. Fifth, most students used either knowledge or observation in their creative process, making them either Knowledge-oriented Type or Observation-oriented Type. In addition, there were DT Type, DT-CT Type, and DT-CT-AT Type among the students, based on the kinds of creative thinking skills they mainly used in the process. This study provides implications for educators and researchers in scientific creativity education.

  • This study analyzed the science texts covering 'air pressure' and 'wind' in common with every curriculum from the syllabus period to the $7^{th}$ curriculum in terms of Systemic Functional Linguistics. Important findings revealed in this study were as follows: In the aspect of ideational metafunction, the texts including much scientific information were reduced by curriculum revision. Most forms of information were 'definition' and 'fact' rather than 'principle'. In the aspect of interpersonal metafunction, the gap between students and texts were getting closer and the social position of students were concerned gradually by curriculum revisions. In the aspect of textual metafunction, the ratios of technical terminology and notation were reduced, however the amount of texts in science textbooks were reduced as well. While the subject was presented in the early texts, it was omitted as time went on. The consistency of subject and theme were reduced in the $7^{th}$ curriculum remarkably.

  • In this study, we investigated the philosophical background and progress of the 2022 revised curriculum development in the high school earth science field. Research that was not covered in the research report includes the relevance of the transformative competency of OECD Education 2030, and that core ideas and achievement standards are organized around knowledge understanding, process functions, and value attitudes that constitute the learning compass needle. In addition, the composition of core ideas and Earth science electives in light of the understanding-centered curriculum, and IB type inquiry-based teaching and learning. Main research results include that the 2022 revised Earth science curriculum emphasized the student agency to foster the transformative competency and scientific literacy, and the curriculum document system in the field of earth science uses a learning compass needle. In addition, based on the understanding-centered curriculum, core ideas of Earth science were derived, and elective courses were organized to help students reach these core ideas. Also, IB-type inquiry-based teaching and learning was emphasized to foster student agency with knowledge construction competency. Based on the research results, slimming of the national and general level curriculum, the need to develop process-centered assessment methods for value and attitudes, the need for curriculum backward design, and ways to develop student agency through inquiry-based teaching and learning were suggested.

  • Inscriptions are integral parts of the current science textbooks, and become medium that makes sense of scientific concepts effectively. This study analyzed the inscriptions from five science textbooks at the secondary level in terms of its type, function, and structures. Analyzing types of inscriptions resulted that the ratio of frequently used photographs and illustrations were much higher than that of graphs and tables used. In case of function analysis, illustrative and complementary functions were dominant in terms of frequency and ratio, whereas explanatory, decorative and inquisitive functions were relatively rare. Inscriptions of single structure was much more than multiple structure. Multiple structure of pair and series were mainly used for representing contrast and sequence, respectively. The proportion of inscriptions in type, function and structure across the textbooks was significantly different. Based on the results, it was suggested that semiotic study about the function and the structure of inscriptions need to be carried out in earth science area to better understand the pedagogical implications of inscriptions in school science.

  • In an advanced computer and information network technologies, users are rapidly approaching environment in which information will be created, delivered, managed and stored, using vastly different methods to traditional pap r based systems. Information seeking behavior contains not only physical access, but also cognitive process in which reading, viewing, analyzing, reasoning etc. The most Important factor determining the usability of electronic documents is cognitive process. But, currently Navigation tools for using electronic documents depend on physical searching without considering cognitive process. Therefore, this study examined feasibility of using overal cognitive process in developing navigation tools. Six cognitive process style have been analyzed to find common skill of information seeking process. Also this study suggests skills that needs to introduce to functions of navigation tool, such as searching, filtering, visualization, traversal, content structure.
