The present study assessed children's perceptions of risk of sexual abuse before and after participation in a sexual abuse prevention program, and investigated the effects of the sexual abuse prevention program on the children's emotional response. The subjects for this study were 135 3rd and 145 6th graders, attending elementary school in Seoul. Instruments were the Sexual Abuse Situational Risk (Jacobs, Hashima, & Kenning, 1995) and the Children's Emotional Response Questionnaire (Garbarino, 1987). The results of this study were that (1) children's perceptions of the risk of sexual abuse by a stranger decreased, relative to those by familiar persons which increased after the program. Especially, 6th graders had higher perceptions of the likelihood of abuse by familiar persons than 3rd graders. Girls had higher perceptions of risk than boys. (2) Children perceived adults as more dangerous than adolescents both before-and after-program. (3) Children's perceptions of the risk of sexual abuse in public settings decreased, relative to perceptions of risk in private settings which increased after the program. Girls had higher perceptions of the liklihood of abuse in private settings than boys; no significant difference was found by grade. (4) Children's emotional response did not reveal a significant change between pretest and posttests.

프로그래밍 교육은 문제 해결 능력과 논리적 사고력 향상에 긍정적인 영향을 끼친다. 하지만 초등학교에서의 프로그래밍 교육은 아직 활성화되고 있지 않다. 그 원인 가운데 하나는 체계적인 교육과정의 부재이다. 본 논문에서는 교육용 프로그래밍 언어인 스크래치를 사용하여 초 중등학교 정보통신기술 교육 운영지침 개정안의 '정보처리의 이해' 영역의 교육과정을 설계하였다. 학습자의 인지부담을 최소화하기 위하여 1~2학년은 4차시, 3~4학년은 5차시, 5~6학년은 6차시 분량으로 교수 학습 지도안을 작성하여 제시했다. 전문가 집단을 선정하여 제시한 교육과정과 교수 학습 지도안을 검증하였다. 검증 결과 학습 대상, 교육요소, 학습내용, 학습량, 교수학습지도안의 적정성 등 거의 모든 영역에서 적절하다는 결론을 얻었다. 본 논문에서 설계한 교육과정을 실제 수업에 적용한다면 초등학교 프로그래밍 교육을 효율적으로 수행할 수 있을 것이며, 더 나아가 초등학생들의 논리적 사고력, 문제해결력, 창의력, 정보처리능력 등을 신장시킬 수 있을 것이다.

The purpose of this study was to examine the awareness level of the prolonged sound rules in elementary school students. The participants in this study were 148 elementary school students in grades 1 through 6. Their awareness level of the prolonged sound rules was evaluated on reading tasks composed of 40 words and sentences. An one-way ANOVA followed by Scheffe hoc tests showed the showed the statistically significant difference between the groups for the awareness level of prolonged sound rules. The younger the children, the larger differences in the awareness of prolonged sound rules. The awareness might affect their cognitive development and a systematic instruction may be helpful especially in lower graders. In conclusion, the findings of this study showed significant differences in the awareness level of the prolonged sound rules at both words and sentences level. It was also found that as the age of children increases, the awareness level of the prolonged sound rules tends to increase which appeared to be completed by the 3rd grade.

The purpose of this study is to investigate how $3^{rd}$ and $4^{th}$ grade elementary students view about 'Science story', which is recently inserted in the new version of science text books. For the study, four hundred $4^{th}$ graders at four schools were considered in the area of Cheonan city, Chungnam province. The degree of student's preference, preferable science topics from the 'Science story', the reason for their preference, and their attitudes toward general science were examined. The study was initiated after student's reading of the 'Science story' (Advanced science, Science in the life, Science in the history, and Future science directions). The student attitudes toward general science were examined using questionnaire survey prior to others. The results of the study are summarized: First, the students who have more interests and affirmative attitudes about science subjects with high scores are more favored about 'Science story'. Second, generally the students prefer reading topics in the order of 1) Science in the life, 2) Advanced science, 3) Science in the history, and 4) Future science directions. However the order was flexible depending on student's gender, preference, and attitudes. Third, the student's interests about 'Science story' was mostly raised from the new scientific topics in the book. And it was also raised partly from their personal interests and usefulness for science learning. Based on the results of our study, we included some suggestions for the improved 'Science story' and their utilizations.

The purpose of this study was to investigate the influence of the energy campaign environmental education of 3rd graders in elementary school in Seoul. The students were divided into an experiment group and a control group. A reconstructed questionnaire through Kim(2005) and Lee(2005)'s test tool was used to survey the effects of applying the energy campaign environmental education program. The i-STATistics program was used to analyze the results. The major results of this study are as follows. First, the researcher was able to develop and apply teaching-learning model for energy campaign environmental education by extracting and recreating the energy education-related contents from the lower grades(1, 2, 3 grade) in 2007 elementary school curriculum. Second, this program had a positive effect on pro-environmental altitudes of elementary school students. Third, this program had a positive correlation among the 3 subdomains of cognitive, affective and behavioral. Fourth, according to qualitative analysis, the students appear to be more concerned in the overall environmental problems containing energy problem and showed a higher will to act while participating in the environmental education through energy campaign program. In conclusion, this program is more directly effective than lectures on energy following the curriculum to improve student's pro-environmental altitudes. Therefore, more intensive research on teaching and learning activities should be highly considered.

This study was conducted to develop a nutrition education workbook to improve picky eating in children and to evaluate the effect of nutrition education using this developed workbook. The developed workbook focused on 2nd and 3rd grade students and consisted of five units. The contents included: multi-grain, vegetables (2 units), fish, and milk. The activities, including observation, and learning the roles and names of the foods, were developed mainly to increase motivation for eating a balanced diet. This workbook was developed from April to December 2008, and was applied at 15 elementary schools containing 1,674 students from April to September 2009 in Changwon City, Korea. We evaluated changes in knowledge before and after education on nutrition, eating behavior, dietary habits, and educational activities using self-administered questionnaires. The children demonstrated significant improvements in nutritional knowledge (P<0.001), eating behavior (P<0.001), and dietary habits (P<0.001). Most of the children answered that the education program was helpful and exciting. Based on these results, we believe that the developed workbook is suitable for children picky eaters, and hope it will be used in the field of child nutrition education.
