An appraisal of the sequential coherence between primary-secondary curriculum : A study on the organization and presentation of content knowledge in the primary science curriculum

본 연구에서는 초․중등 교육과정 간 연계성 문제를 초등 과학교육과정에서 교육내용이 제시되는 방식을 중심으로 살펴보기로 한다. 본 연구는 과학교육과정의 경우 초․중등 학교급간 교육과정상의 연계성에 있어서 괴리가 비교적 뚜렷하다고 가정하고, 그러한 괴리를 초래하는 한 가지 이유를 과학교육내용을 선정하는 논리에서 발견할 수 있는 과학교과 지식의 성격을 파악하는 관점에까지 거슬러 찾아보고자 하였다. 그리고 그러한 관점이 교육과정 문서나 교과서에서 해당 교육내용을 제시하는 방식에 어떻게 반영되어 있는지 논의하고자 하였다. At the time of transfer from primary to secondary schooling, many students experience difficulties because of extreme differences in curriculum between the two sectors. With pursuing such interest, this study investigates the sequential coherence between primary and secondary curriculum. This study focuses on different forms of curriculum organization in science curriculum. This study examines such different forms in three level, curriculum document, textbook and classroom lesson of curriculum organization and presentation of subject contents. First, it is discussed that curriculum developers in science education tend to use rhetoric dichotomy to organize curricular contents, which is activity-based contents and conceptual knowledge in the subject matter. These two criteria have undoubtedly been legitimated to make cohesively sequential the organization of primary-secondary science curriculum. This study discusses that such a dichotomy reflects a partial viewpoint of the respective subject knowledge, and moreover it disrupts the sequential order for transfer between the two sectors. Second, this study identifies, in primary science curriculum materials and textbooks, such a dichotomy in the way of how those materials present subject contents. Implications about different ways of organizing primary science curriculum with an integrated form of the curricular knowledge are reformulated

Habitat characteristics of Scutopus sp.-K (Mollusca: Caudofoveata: Limifossoridae) and its appearance in the East Sea of Korea

Starting from November 2013 to April 2015, collection of sediments as well as biological specimen was carried out at 45 sampling stations to understand inhabitation and distributional pattern of species belonging to Class Caudofoveata in coastal waters of Korea. The results indicated that 1 species belonging to Class Caudofoveata were collected with a range of 10 mm in length and those were identified as Scutopus sp. (Family Limifossoridae). This finding was meaningful in that 2 species in total belonging to Family Limifossoridae were found besides Chaetoderma japonicum which was previously identified. Most Scutopus sp.-K collected in this study was appeared at the depth of 150-160 m in southern part of the East Sea, especially in the depth of 1,600 m central part of the East Sea and 90 m in northern part of the Yellow Sea. Therefore, it can be concluded that Scutopus sp.-K was distributed at the range of 90-1,600 m in depth and sediments where the species in habitat had 6.23 φ in the mean grain size.22Nkc

4차원 N=1 초중력 이론 라그랑지안으로부터 부드럽게 초대칭을 깨는 항들의 계산

학위논문(석사) - 한국과학기술원 : 물리학과, 2003.2, [ iv, 47 p. ]We construct 4D N=1 supergravity Lagrangian in terms of component fields in Weyl-compensator formalism. Next we compute soft terms from this model with hidden sector and Weyl-compensator breaking SUSY at an intermediate energy scale. Additionally, we derived the soft terms from the 1PI effective action and show that super-Weyl anomaly effect generate one-loop gaugino mass, one-loop trilinear A-term and two-loop scalar mass squared.한국과학기술원 : 물리학과

Latitudinal Variation of the Number of Species and Species Diversity in Shelled Gastropods of Eastern Coast of Korea

In the present study we examined latitudinal trend of the number of species and species diversity of rocky subtidal shelled gastropods. Specimens were sampled from four wave-exposed sites along the eastern coast of Korea between Sockcho (38°14″N) and Busan (35°06″N), covering a range of over ca. 440 km and 4° of latitude. At a small local scale, the number of species showed a latitudinal trend, decreased with decreasing of latitude, even though no clear trends in species diversity were detected. The present result, consequently, suggest that regulation of small-scale local diversity presumably results from the difference of the local micro-environment.22Nkciothe
