The aim of this study was to evaluate the body composition difference and obesity prevalence in grade 5 to 8 by gender. A total of 1,333 students, 707 boys and 631 girls, were recruited from one elementary and one middle school in Seoul, Korea. Anthropometric measurements including height, weight, lean body mass, and body fat were assessed. Height and weight were increased by grade, but Body Mass Index (BMI) by grade showed no significant difference among boys. Lean body mass had growth spurt between 7 and 8 grade among boys compared to gradual increase among girls. Overweight and obesity prevalence were higher among elementary schoolers than middle schoolers. Overweight (BMI for age> $85^{th}$ percentile) prevalence was about $44\%$ among $5^{th}$ grade boys compared $29\%$ among same grade girls. These results provided that there were prominent difference regarding body growth and obesity prevalence in gender and grade. Further studies for children and adolescents should be considered their body composition change.

Whether and when naturalistic or supernaturalistic explanations of the origins of sun and earth, humans, life and species change with development was explored in a questionnaire and interviews with 32 first graders and 32 second graders, and in a questionnaire with 34 third graders, 32 sixth graders and 38 eighth graders. Participants were also asked about factors affecting their explanations in the questionnaires. Even the first and second graders could consistently provide supernaturalistic or naturalistic explanations on both the origins of sun and earth, and of humans. There was an age-related developmental shift from supernaturalistic to naturalistic explanation. As for origins of species, most of the first and second graders held the spontaneous generationist explanation, and after the third grade their views divided into evolutionist and creationist explanations. Students' explanations of species origins were established by the sixth grade through a transitional stage in the third grade. At the first and second grade levels, books and the children's own reasoning mainly influenced the views of origins, whereas parents and school were not perceived as being important. For the third graders and higher-grade levels, several factors, including parents and religion, were perceived as being important. These results show that explanations of origins start to develop earlier than or during the first grade, and are established by the sixth grade; moreover, the formation of these views is affected by several factors in addition to development.

수학 학업성취도에 영향을 미치고 있는 교사의 성취압력과 열의는 끊임없이 변화하면서 수학 학업성취도 영향을 미치므로 그 변화양상이 학업성취도의 변화양상에 미치는 영향력을 살펴볼 수 있는 종단연구가 필요하다. 본 연구는 한국교육종단연구2013의 초등학교 5학년(2013년)부터 중학교 3학년(2017년)까지의 학생 데이터를 활용하여 수학 학업성취도에 대한 종단적인 변화양상이 유사한 하위 그룹으로 분류하여 그룹별 교사의 성취압력과 열의에 대한 종단적인 변화양상이 수학 학업성취도의 종단적인 변화양상에 미치는 영향력과 그 경로를 비교·분석하였다. 분석결과 수학 학업성취도의 종단적인 변화가 유사한 4개의 하위그룹 모두 교사의 성취압력은 초등학교 5학년부터 변화가 적은 반면에 교사의 열의는 초등학교 5학년부터 지속적으로 떨어지는 것으로 나타났다. 또한, 그룹별 학생들이 인지하는 교사의 성취압력과 열의가 수학 학업성취도에 미치는 영향력은 다르게 나타났다. 이것은 수학 학업성취도의 향상을 위해서는 학생들의 특성과 성향을 반영한 교수 학습의 지원이 필요하다는 것을 시사한다.

Though the investigation of the suggested references proverbs related weather were collected and considered the probability of the usage on science instruction. The results are as follows. 130 proverbs related to weather were collected through the investigation of the suggested references. Most of weather proverbs are based on the states of sky, clouds, wind, precipitation, actions of animal, states of plants and the condition of people in daily life. they were classified according to weather types, natural phenomena and seasons. According to the results of analysing the students' recognition and interests on weather proverbs, most of students heard weather proverbs in their elementary school years firstly through their parents, books, and teachers. However they have only heard a few. Also many students also tend to think weather proverbs have a scientific base because weather proverbs have been told by many people through the ancient time and correspond to their personal experiences. Students responded that weather proverbs are useful for science learning on weather and can teach heritage and wisdom. After reading the suggested weather proverbs, their interests on weather proverbs were increased more than before reading. This is one of reasons why weather proverbs can be introduced to science classes. Weather proverbs were considered related to science curriculum. The third grade has a Unit "Fine days and Cloudy days", the fifth grade, "Unit of Weather Change", the Sixth grade, "Unit of Weather Forecast" , the Ninth grade, "Unit of Water cycle and Weather Change" and the tenth grade has "Unit of Earth". So the author consider that weather proverb materials can be used so effectively to bring about interest and motive in science learning.

In the present study, in order to improve elementary students’ nutrition knowledge and form correct eating habits, dietitian in charge executed nutrition education for 4th-, 5th- and 6th-grade students at Namchang Elementary School in Suwon, Gyeonggi-do using various educational media for five weeks and two sessions a week (a total of 10 sessions) through discretional activity classes. As for change in nutritional knowledge after nutrition education, 4th-grade students showed improvement by 24.3points(p<0.001), 5th-grade ones by 18.0(p<0.001), and 6th-grade ones by 16.7(p<0.001). With regard to change in dietary habits after education, no effect was observed in the improvement of dietary life but the score of dietary habits was improved as a whole. Nutritional knowledge and dietary habits were in a positive correlation with each other before education(r=0.406, p<0.001), but in no correlation after education. Nutritional knowledge and dietary habit practice plan were in a positive correlation after education(r=0.310, p<0.01). With regard to nutritional knowledge after nutrition education by children’s body type measured using Rohrer Index, knowledge increased significantly in normal children(p<0.001), obese children(p<0.001) and highly obese children(p<0.05) but not in slim children. the effect of education was not significant for children’s dietary habits. Practice plan showed significant changes in all of children(p<0.001). This suggests that nutrition education should be executed from early age. It is necessary to define the goals of systematic nutrition education fit for children’s level and to develop various education programs and teaching materials.

This study was conducted to investigate the effects of 10-week dietary education on elementary students in an after-school program in Seoul. Participants were 20 1-2 grade students and 283-6 grade students, and the dietary program consisted of dietary education and activities focused on children's levels of understanding. The results were as follows: Total participant's food habit scores and nutrition knowledge significantly increased (p<0.05) after dietary education. Food habit and nutrition knowledge scores of lower grade participants (grade) increased desirably (p<0.05). Meanwhile higher grade participants' (grade) food habit scores also changed (p<0.05), but their nutrition knowledge scores were changed. Boy's food habit scores significantly changed (p<0.05), whereas girl's food habit scores did not change significantly. Further, female participants' nutrition knowledge scores did not changesignificantly after education. Participants' obesity knowledge scores significantly changed after the education (p<0.05), but their attitudes on obesity increased insignificantly. Lower grade participants' attitudes on obesity significantly and desirably changed (p<0.05), whereas higher grade participants' attitudes on obesity changed insignificantly. Girl's knowledge and attitudes on obesity significantly and desirably changed (p<0.05-0.01). This study revealed the correlation between food habit scores and attitudes on obesity (p<0.01), demonstrating that participants with high food habit scores have advisable attitudes on obesity. The result of this study shows that lower grade participants' food habit scores, nutrition knowledge, and attitudes on obesity changed desirably after dietary education. Therefore, this study promote the development of adequate nutrition education and materials focused on lower grade students and the need for systematic and continuous dietary education programs based on elementary school.
