Due to the fast changing social and physical environment, the clothing behaviour of elementary school students should have been changed. Since previous research was completed a long time ago, new research must be conducted to understand the relationships of the clothing behaviour of elementary school students in terms of the time of research, gender and grades. Third and sixth grades in Susan were sampled in 2002; the secondary data in 1988 was used. Factor analysis and Lisrel's group analysis were conducted. The results indicated as follows: 1. As there was an increased interest in clothes, the comfort of the clothes was decreased at the higher grades in 1988, and the low and high grades in 2002, and the clothes of boys in high grade increased in the manageability in 2002, but nor with boy students in the low grade neither all types of students in 1988. 2. As there was an increased manageability in clothes, all types of girl students became more independence in choosing their own clothes. However, boy students in the low and high grades only increased their independence in choosing their own clothes in 1988. 3. As there was an increased comfort of clothes, there was not a significant relationship with the independence of students for choosing their clothes concerning the gender, the grades and the period of research. 4. As there was an increased interest in clothes, the low grade girl and boy students in 1988 increased in their independence in choosing their clothes. However, the high grade boy students in 1988 significantly decreased their independence. Thus there are different results in the clothing behavior in the elementary school student concerning the time of study, gender and grades.

The purpose of this study was to explore North Korean immigrant elementary students' cognitive and affective characteristics related to science education. A total of 68 North Korean immigrant students enrolled in 3 to 6 grades and 133 South Korean students in 4 and 6 grades in 3 South Korean elementary schools participated in the study. A short version of Group Assessment of Logical Thinking(GALT) was used to investigate the students' levels of logical thinking, and the Enjoyment of Science Lessons Scale(ESLS) of the Test of Science Related Attitudes(TOSRA) was administrated to examine their attitudes towards science lessons. The statistical analysis of data revealed that the level of logical thinking of the North Korean immigrant elementary students was very low and that this was also the case for the South Korean students. Especially, the mean score of logical thinking of the North Korean immigrant 6 graders was much lower when compared with that of the South Korean counterparts. For both the North Korean immigrant students and South Korean students, the enjoyment of science lessons decreased as they progressed through higher grades. This decreasing trend, however, turned out to be more serious in the South Korean elementary students. Based on these results, suggestions were presented to help successful science learning of North Korean immigrant elementary students.

Background and objective: This study was conducted to find out the status of plant utilization in the current textbooks by analyzing the plants by grade and subject in the national textbooks for all elementary school grades in the 2015 revised curriculum in Korea. Methods: The data collected was analyzed using Microsoft Office Excel to obtain the frequency and ratio of collected plant data and SPSS for Windows 26.0 to determine learning content areas by grade and the R program was used to visualize the learning content areas. Results: A total of 232 species of plants were presented 1,047 times in the national textbooks. Based on an analysis of the plants presented by grade, the species that continued to increase in the lower grades tended to decrease in the fifth and sixth grades, the upper grades of elementary school. As for the number and frequency of plant species by subject, Korean Language had the highest number and frequency of plant species. The types of presentation of plants in textbooks were mainly text, followed by illustrations and photos of plants, which were largely used in first grade textbooks. In addition, as for the area of learning contents in which plants are used, in the lower grades, plants were used in the linguistic domain, and in the upper grades, in the botanical and environmental domains of the natural sciences. Herbaceous plants were presented more than woody plants, and according to an analysis of the plants based on the classification of crops, horticultural crops were presented the most, followed by food crops. Out of horticultural crops, flowering plants were found the most diversity with 63 species, but the plants that appeared most frequently were fruit trees that are commonly encountered in real life. Conclusion: As a result of this study, various plant species were included in elementary school textbooks, but most of them were horticultural crops encountered in real life depending on their use. Nevertheless, plant species with high frequency have continued a similar trend of frequency from the previous curriculums. Therefore, in the next curriculum, plant learning materials should be reflected according to social changes and students' preference for plants.

The purpose of this paper was to analyze the characteristics of Korean science curriculum and the differences with the other country. For this purpose, the USA was selected as the target country for comparison. The comparison focused on goals and contents in science curriculum document. The goals for science education in both countries were similar. But the goal setting level was different. Also, four objectives were suggested in Korean curriculum and nine objectives in the USA to achieve the general objective. Korean curriculum was composed of such grades system as 3rd & 4th grades, 5th & 6th grades and content area as 'materials and energy', 'life and the earth' in content system. And the USA composed in the such grade system as K, Grade 1, 2, 3, 4 and 5. Also the elements to be learned is suggested in the strand. And in the area of the earth and space in the Korean Curriculum, there are elements emphasized in the content area, cognitive area, context category and practical activities learning objective category. But the USA covered most of those elements evenly. Korean curriculum focused on learning of certain elements in certain grades, but the USA curriculum is to learn several elements evenly in every grade. It will be future topics of research to investigate the effect of curriculum with different emphasis of improving students' scientific knowledge and learning through further study.

본 연구는 초등학교 학생들의 학년과 성적에 따른 실태를 조사하였다. 공간 능력은 크게 공간관계와 공간시각화로 나누고 그 하위요소들을 각각 3가지와 5가지로 두어 자세하게 분석하고자 하였다. 학년에 따른 공간능력의 실태를 살펴보면 고학년일수록 그 능력이 높았으며, 성적에 따른 공간능력의 경우, 성적 우수 아동이 그 능력이 더 높은 것으로 조사되었다. 그러나 교육과정에서 해당 공간능력을 다루느냐, 다루지 않느냐에 따라 상이한 차이를 보였다. 따라서 본 논문은 이와 관련하여 교수학습 과정 및 현재 교육과정에 시사점을 제공하고자 한다.

이 연구는 학년이 상승하면서 초등학생들의 자연수 계산 오류가 어떤 양상을 띠며 변해 가는지를 알아보고, 이를 통해 효율적인 계산 지도를 위한 시사점을 도출하고자 시도되었다. 이를 위해 수도권의 한 초등학교 3, 4, 5, 6학년 580명을 대상으로, 동일한 뺄셈, 곱셈, 나눗셈 검사지를 풀게 하였으며, 미리 설정한 오류유형틀에 입각하여 학생의 오답 반응을 분석하였다. 학생들의 반응을 분석한 결과, 세 계산 영역에서 학년 상승에 따른 계산 수행능력의 향상이 통계적으로 유의미한 수치로 나타났으며, 계산 절차를 처음 배우는 시점에서 차년도까지의 향상 폭이 가장 큰 것으로 나타났다. 그러나 초등학생들의 계산 오류는 일회 혹은 이회 정도 반복되지만 삼회이상은 잘 반복되지 않는, 체계성이나 고착성이 비교적 낮은 것으로 드러났다. 마지막으로, 이러한 내용을 바탕으로 계산 지도의 효율성을 높이기 위한 지도 전략을 제안하였다.
