In this study, we analyzed the effects of data visualization education with using Python on the improvement of computing thinking ability of the 6th grade students of elementary school. Based on the results of the needs analysis of 60 elementary school teachers and 120 elementary school students, we developed the data visualization education program. In the developed educational program, 24 elementary school students were trained for 6 days and 36 hours in total. Thereafter, students were subjected to pre- and post-comparison tests. As a result of the analysis, it was found that the data visualization education with using Python is effective in improving the Computational cognition, Fluency, Originality, Elaboration of the 6th grade students in elementary school.

We must know computer terms to use, learn, and understand efficiently. It is important for the elementary school students who learn computer for the first time to understand computer terms correctly. This study investigates a computer terms in the elementary school computer textbook which have been used currently at the elementary school, selects suitable computer terms for the elementary school student, analyzes and classifies them as a 1 2th grade, a 3 4th grade, 5 6th grade by the elementary school computer curriculum, and also classifies those as information ethics, computer basic, application software, computer communication by the category. The expectations of this study are as follows. First, the result of this offers teacher to a computer terms guidance for usability which is essential to elementary school's computer class. Second, this can be used as a reference in making a elementary computer textbook or studying and training textbook for teachers. Third, this offers teachers to an important criteria when they select a computer textbook for elementary student in elementary school.

Mathematical justification is essential to assert with reason and to communicate. Students learn mathematical justification in 8th grade in Korea. Recently, However, many researchers point out that justification be taught from young age. Lots of studies say that students can deduct and justify mathematically from in the lower grades in elementary school. I conduct questionnaire to know awareness and steps of elementary school students and middle school students. In the case of 9th grades, the rate of students to deduct is highest compared with the other grades. The rease is why 9th grades are taught how to deductive justification. In spite of, however, the other grades are also high of rate to do simple deductive justification. I want to focus on the 6th and 5th grades. They are also high of rate to deduct. It means we don't need to just focus on inducing in elementary school. Most of student needs lots of various experience to mathematical justification.

21세기의 세계화, 정보화 시대를 주도할 자율적이고 창의적인 한국인을 육성하기 위하여 제7차 교육과정은 자율과 창의에 바탕을 둔 학생 중심의 교육과정을 표방하고 자기 주도적 학습 능력의 신장에 역점을 두고있다. 이에 따라 자기 주도적 학습 능력신장을 위한 수학과 교수 학습 자료들이 제작되어 보급 활용되고 있으나 구체적 조작기 아동의 특성에 맞는 초등학교 저학년 수학교과의 자기 주도적 학습 능력 신장을 위한 효과적인 프로그램은 부족한 실정이다. 이에 본 연구는 선행 연구 사례들을 분식하여 나타난 단점들을 수정, 보완하고, 초등학교 '확률과 통계'영역 중 3학년 나 단계의 '자료 정리하기' 단원을 재구성하였다. 그리고 이를 웹기반 학습 프로그램으로 개발하여 현장에 적용해 봄으로써 그 효과를 검증하고자 한다.

This study examined elementary students' reading attitudes to identify the state of feeling related to reading. For this, 523 elementary students from the forth to the sixth of 'model schools for reading' participated and completed questionnaires. The results show that the average score of reading attitudes was 3.8 out of 5, and there were differences between schools, gender and grade levels. Girls' reading attitudes were more positive than boys and sixth-grade students' reading attitudes were the most negative of all grades. The students' attitudes of the school which emphasized reading for pleasure were better than that of reading for academic achievement.

Purpose : Traditional herbal medicines may be overused in Korea. Expenditures and inaccuracies of hospital prescription are increasing gradually. So we investigated the frequency and nature of herbal medicine use among elementary school pupils. Methods : We interviewed students of three elementary schools located in Gwangju with survey papers. We analyzed 905 returned surveys. Results : They consisted of 421 males and 484 females. Five hundred ninety (65.2 percent) of pupils who have taken herbal medicines since birth. First grade made up 74.1 percent, 2nd grade 63.0 percent, 3rd grade 64.8 percent, 4th grade 63.3 percent, 5th grade 65.5 percent, and sixth grade 61.9 percent, respectively. The mean frequency of herbal medicine use was 3.2 times. 6th grade was 3.3 times, 5th grade 3.9 times, 4th grade 3.7 times, 3rd grade 2.7 times, 2nd grade 2.7 times, and 1st grade 2.6 times, respectively. The mean cost of herbal medicine use was from 50,00-100,000 won. The mean age of pupils who took their 1st herbal medicine was 55 months, 6th grade 67 months, 5th grade 58 months, 4th grade 54 months, 3rd grade 55 months, 2nd grade 51 months, and 1st grade 47 months. The most common reason of herbal medicine use was "looking weak, without disease." The rate of elementary pupils who had good effects was 63.7 percent; the rate of side effects was 4.5 percent. Conclusions : The rate of elementary pupils who took herbal medicines was high and gradually higher in lower grades. So, clinicians have to cope directly with this situation and to educate parents about herbal medicines.

The purpose of this study was to identify latent classes in executive function difficulty of first graders depends on evaluations from their mother and teacher and to investigate how its related with their school adaption and academic performance in second grade. Based on the model of the latent profile analysis, the 8th and 9th wave data from Korean Children and Youth Panel Survey were analyzed. The results of this study were as following. First, results showed that there were three types of latent classes in the executive function difficulty depend on evaluations from their mother and teacher: 'low executive function,' 'students who were highly evaluated by mother,' and 'students who were highly evaluated by teacher.' Second, students' executive function difficulty had a direct effect on the students' school adaption and academic performance in their second year of school. Especially students who were evaluated as having the lowest executive function difficulty showed significant higher means than students who were evaluated higher by mother and teacher. This study emphasized the importance of multiple evaluation in students' executive function difficulty to provide an educational intervention.

'Sentence posing' is newly given in the third through sixth grade mathematics textbooks of the revised 2007 curriculum to confirm students' understanding on mathematical concepts of definitions. In this paper, we discuss the role of the sentence posing in the third grade mathematics textbooks on the basis of the problems occurred in third graders' sentence posing activities. Overall, it turned out that the role of the sentence posing was somewhat restrictive. Hence the sentence posing needs to be applied to check whether students can properly use the definitions in real life situations. In addition, it is necessary to employ the present role of the sentence posing to confirm students' understanding on mathematical concepts of definitions selectively according to the concepts of definitions.
