영재교육은 영재들이 창의적인 지식 생산자로서의 역할을 수행할 수 있도록 하여 개인의 잠재력을 최대한 계발시켜주어 자아실현을 도모할 수 있도록 해주고 더 나아가 국가 경쟁력을 높일 수 있으므로 학교와 지역사회에서는 영재교육의 활성화를 위하여 다양한 영재교육 프로그램을 개발하고, 영재에게 적합한 교수-학습 자료를 마련하여 그들의 흥미와 빠른 학습 속도를 충족시켜줄 수 있도록 심화된 학습 기회를 제공하기 위해 노력해야 한다. 그러나, 이미 연구된 자료들을 살펴보면 초등학교 고학년을 위주로 하는 영재 교육 프로그램이 대부분이어서 저학년 영재아동을 위한 자료는 전무한 실정이다. 따라서 본 연구에서는 초등학교 저학년 단계에서 수학분야에 영재성이 있거나 흥미를 가지고 있는 아동을 위한 수학 심화학습 프로그램을 개발하고자 한다.

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.

I apply it at early morning classes on elementary school students and analysis the responses of students to science communication activity. In order to achieve this goal, the review on preliminary studies and relevant documents were carried out and program called 'The aroma of science encountered in the forest of science' as the contents of daily life-centered theme that can be easily understood by students in elementary school was selected. Moreover, themes of total 15 episodes were determined by analyzing their contents. The materials were applied to science communication activity targeting 1 class with 21 students in second grade of elementary school. The survey on the responses toward the activity was conducted after the activity. The result of analyzing the survey, students displayed positive response toward science communication activity utilizing 'Science TV'. The result of the activity analysis and survey analysis after the activity displayed that students passionately participated in science communication activity utilizing 'Science TV' in early morning classes on elementary school. Also, students displayed positive response toward science communication activity utilizing 'Science TV' such as the increase in the understanding of science, and others.

Measurement is an imperative content area of early elementary mathematics, but it is reported that students' understanding of units in measurement situations is insufficient despite its importance. Therefore, this study examined lower-grade elementary students' quantitative reasoning of units in length measurement by identifying the levels of reasoning of units. For this purpose, we collected and analyzed the responses of second-grade elementary school students who engaged in a set of length measurement tasks using an open number line in terms of unitizing, iterating, and partitioning. As a result of the study, we categorized students' quantitative reasoning of unit levels into four levels: Iterating unit one, Iterating a given unit, Relating units, and Transforming units. The most prevalent level was Relating units, which is the level of recognizing relationships between units to measure length. Each level was illustrated with distinct features and examples of unit reasoning. Based on the results of this study, a personalized plan to the level of unit reasoning of students is required, and the need for additional guidance or the use of customized interventions for students with incomplete unit reasoning skills is necessary.

After we compared the Unaided visual acuity and the Corrected visual acuity who were wearing spectacles, all over elementary school in Iksan, we could get conclusions like these. 1. The grades are getting higher, there are more who are 0.6 unaided visual acuity, and getting higher Corrected who were wearing spectacles. 2. There are 30% who have to change their wearing spectacles. 3. Higher grade separated into good or worth visual acuity then lower grade. 4. When the first grade grow up third grade, change of unaided visual acuity increased at 0.2, decreased 0.7 and 1.0, but the case of fourth grade becomes sixth grade shown a little changes unaided visual acuity.

Science textbook is the most frequently used teaching material in elementary schools of the United States and Korea. Elementary science textbooks of the United States and Korea are analyzed to find out the educational objectives and characteristics of contents shown in textbooks. About 100 pages each in the first grade and fourth grade science textbooks each nations are selected randomly for educational objective analysis. Life science contents of 1st to 6th grade are analyzed from elementary science textbooks of the United States and Korea. The analyzed textbooks in Korea are 'Wise life,' an integrated subject with social studies and science, and 'science.' The analyzed elementary science textbooks of the United States are Harcourt Science, which is one of the frequently used textbooks. The educational objective framework used includes science knowledge, scientific inquiry, scientific attitude, STS, and philosophy and history of science. The results show science textbooks of the United States emphasize scientific knowledge more than scientific inquiry. Korean science textbooks emphasize scientific inquiry more than scientific knowledge. Elementary science textbooks of the United States present some life science topics redundantly and expose more difficult topics than Korean.

The objective of the paper is to analyze the extent to which elementary school students acquired, perceived, and practiced oral health knowledge provided by an elementary school-based oral health clinic (SBOHC). It is respectively investigated by gender and year of school. The paper will be relevant for developing specified oral health programs in elementary SBOHCs. By choosing three elementary schools that operate SBOHC in the school district of Daejeon Metropolitan City from April 11 to April 30, 2013, a self-administered questionnaire was given out to be answered directly by 350 students in the 4th, 5th, and 6th grades and their responses were collected. Of the collected responses, 326 responses were explored by using the SPSS 12.0. Those students' scores of oral health knowledge are found to be statistically meaningful for school year, not for gender. In them are included correct tooth brushing time, dental caries symptoms, gum disease symptoms, and correct tooth brushing method. Change in tooth brushing method after oral health education showed the statistically meaningful difference for gender and school year. In conclusion, every SBOHC should develop a variety of specified educational programs that depend on gender and grade in each elementary school.

This study examined the longitudinal relationship between academic achievement and school satisfaction using a data of the Seoul Panel Study of Children(SPSC). Fully autoregressive cross-lagged analysis and multi-group comparison were performed to measure the longitudinal relationship between two constructs as well as differences between poverty and non-poverty groups. The results showed that both academic achievement and school satisfaction were stable over time in non-poverty group. Academic achievement at the 4th grade significantly affected the school satisfaction at the 6th grade and it subsequently affected on the academic achievement at the 8th grade in non-poverty group. In contrast, academic achievement was not consistent over time in poverty group. Only the school satisfaction at the 6th grade affected the academic achievement at the 8th grade. The findings of this study have various practical implication for school interventions. It is more important to keep supporting the children to maintain the level of academic achievement in non-poverty group. While, in poverty group, it is essential to make school satisfaction and academic motivation increase with school attachment programs.
