언어는 모든 교육에서 중요한 역할을 담당하므로 국어 교과목은 교육의 기본 목표인 언어사용의 신장을 위해서 중요하게 다루어지고 있다. 언어발달을 위한 국어 교육활동은 듣기, 말하기, 읽기, 쓰기의 네 가지 영역에 기초를 두고 있으며 학생들의 흥미를 유발할 수 있는 쌍방향 멀티미디어를 이용하면 이러한 영역의 학습효과를 증가시킬 수 있다. 그러나 기존의 웹사이트의 개발 사례를 살펴보면 교과서 중심인 일방적인 제사만이 구현되어 있다. 따라서 본 논문에서는 흥미와 자발적인 참여를 유발하고 행동한 것에 대해 즉각적인 반응(Feedback)을 주는 애니메이션과 음성, 효과음, 높이, 학습, 게임으로 결합된 오락적인 쌍방향 멀티미디어 웹 컨텐츠를 개발하여 언어를 배우는 어린이들의 학습능력의 향상과 창의적인 언어 활동의 증대에 기여하고자 한다. 특히, 이 시스템의 큰 특징은 학생에 대한 학습 결과를 도출하고 이에 대한 해결책 및 각종 정보를 추출하여 학습진단 결과, 재학습, 학습독력의 형태로 학생 개개인에게 메일로 보내는 학습 통합관리 기능을 포함하고 있다는 것이다.

A talented person in a knowledge based society is the person who has ability to create intellectual property value. This intellectual property comes from invention. According to several researches, invention and creativity have a strong correlation. And a manifestation of creativity is related to family background and parenting styles of a student. This narrative research is to understand creativity factor, family background and parenting styles of five foreign inventors in elementary textbooks. As a result of study, all of the inventors had intellectual curiosity, originality and sophistication. And despite economically difficult environment, they grew up in houses where gives an educational opportunity and their relationships with family members were good. Also at least one of their parents supported their decision and they participated in the education for their children.

We have compared Korean and American mathematics curriculums in 5 areas: whole number(concepts and its operations); geometry; pattern and relations; measurements; statistics and probability. We have found significant differences in geometry area. Korean curriculums contain simple planar figures (circles, triangles, rectangles, and squres) and some of the spatial figures until 3rd grades. But in America they learn various planar and spatial fugures(cone, pyramid, triangular prism, etc) since the 1st grade starts. They also start the 1st grade by dealing with topological concepts like open/closed, inside/outside, order, etc. As the grade goes on, students learn other geometrical concepts like congruence, symmetry, 3-dimensional views. We also found that American curriculum focuses on students' activities and courages communication through projects, groupwork, journal writing, etc. It's also superior in respects of motivation, and connections with real life and other subjects. Korean curriculum needs more improvements in these aspects. Furthermore for lower graders reviewing sections need to be enhanced for feedback.

This paper is to study theorems related with congruence of triangles in Lobachevskii's and Hadamard's geometry textbooks, and to compare their proof methods. We find out that Lobachevskii's geometry textbook contains 5 theorems of triangles' congruence, but doesn't explain congruence of right triangles. In Hadamard's geometry textbook description system of the theorems of triangles' congruence is similar with our mathematics textbook. Hadamard's geometry textbook treat 3 theorems of triangles' congruence, and 2 theorems of right triangles' congruence. But in Hadamard's geometry textbook all theorems are proved.

Purpose of this study is to analyze the validity of textbook content on practical arts for the 6th curriculum, to grasp the content problems and to propose the strategy of reformation to be satisfied with consumer better than supplier. The data collected from 196 elemantary school teachers who lived in Gyungsang-namdo and analized by SPSS/PC(sup)+ package program. The statistical methods used for analysis were frequency, descriptives, validity, t-test, oneway ANOVA. The major findings can be summarised as follows： 1. The textbooks on practical arts for 3rd, 4th, 5th and 6th grades showed unbalanced division for picture, figure, table unite and evaluation type of all units doesn’t show diversity. 2. The validity of textbook contents on practical arts was found to be the highest for 3rd grade textbook and the lowest for 6th grade one. Among the validity of the evaluation items,‘differentiation with other subject’and ‘usefulness of living’showed high scores, wheres ‘fitness of child level’marked lowest score. 3. There was no significant difference Among the validity contents of teachers based on socio-demographic variables.

The purpose of this research is to analyze the narratives of elementary school history textbooks of Korea and US. The research problems are as follows. Firstly, what are the form and content of narratives of Korea's elementary school history textbook of Korea and US. Secondly, what are the characteristics of narratives of American elementary school history textbook of Korea and US. The content analysis method was utilized for analyzing narratives of textbooks. Research results are summarized as follows. Firstly, the features of Korea's elementary school history textbook are described. Secondly, the features of American elementary school history textbook are described. Thirdly, the common features and differences between both countries' textbook narratives are analyzed. Lastly, the implications for diversifying the narratives of Korea's elementary school history textbook are recommended.

수학은 추상적인 학문이다. '추상'은 몇 개 또는 무한히 많은 사물의 공통성이나 본질을 추출하여 파악하는 사고작용이다. 그리고 이 추상들이 모여 분류(유사성을 기초로 해서 우리의 경험을 함께 묶는 것)가 되고 그 다음에 이름이 붙여진다. 이것이 바로 개념(concept)이 형성되는 과정이고 수학자가 수학을 하는 과정이다. 그리고 이 개념들은 여러 가지 모양으로 결합하여 스키마(Schema)라고 부르는 개념 구조를 형성하게 되는데, 이 스키마(Schema)는 수학적 사고를 하는데 매우 중요한 역할을 한다. 본 논문에서는 기존의 초등학교 교과서의 소수의 관한 내용에서 교차연결고리가 부족한 부분을 보충한 스키마식 수업 모델을 제시하여 수학의 연계성과 위계성을 강조함으로써 학생들로 하여금 수학의 구조를 파악하게 하여 수학에 대한 흥미와 필요성을 알게 하는데 그 목적을 두고 있다.

A large part of students' difficulties with fractional division algorithms in the current algorithm textbooks, seem to be due to self-induction methods. Through concrete analysis of surveys and interviews, we confirmed the educational value of fractional algorithms used to elicit alternative ways of context of determination of a unit rate. In addition, we suggested alternative methods based on the results of the teaching methods and curriculum configuration.

Since 2022, textbooks in elementary school mathematics have been converted from national textbook system to authorization system, but it is pointed out that the composition of these new textbooks is almost the same as the existing national textbooks and the advantages of the authorization system cannot be utilized. Therefore a need has been raised to find out the composition of foreign textbooks. In order to compare the internal system of elementary mathematics textbook composition in Korea and Japan, Wakuwaku Sansu, one of Japan's elementary mathematical textbooks was analyzed and compared with Korean textbooks. As a result of the analysis, it was found that Japanese textbooks have more flexibility in the composition of the unit, the number of hours of the unit, the introduction of special lessons, and emphasis. This analysis will promote the diversity and creativity of the composition of elementary mathematics textbooks in Korea, providing implications for more efficient textbook compilation.

본 논문에서는 사전학습모델을 활용한 수학학습 도구 자동 생성 시스템을 제안한다. 본 시스템은 사전학습모델을 활용하여 수학학습 도구를 교과과정 및 단원, 유형별로 다각화하여 자동 생성하고 사전학습모델을 자체 구축한 Dataset을 이용해 Fine-tuning하여 학생들에게 적절한 학습 도구와 적절치 않은 학습 도구를 분류하여 학습 도구의 품질을 높이었다. 본 시스템을 활용하여 학생들에게 양질의 수학학습 도구를 많은 양으로 제공해 줄 수 있는 초석을 다지었으며, 추후 AI 교과서와의 융합연구의 가능성도 열게 되었다.
