The purpose of this study is to design and practice teaching and learning method for routing algorithm among computer science principle which is difficult to be taught to elementary school students and understood by students. And we find out whether elementary school students can understand those learning contents. Intellectual area was assessed through equivalent test paper before and after the test and emotional area was assessed through students' impressions after class. The test showed that routing algorithm could be taught to children. Therefore, this study presents the learnability of routing algorithm as a learning element of elementary school computer education.

In this study, we develop the mathematical modeling teaching materials focused function units of mathematics textbooks and establish the appropriate teaching and learning model. Using mathematical modeling materials and developed instructional materials for teaching high school students is aimed to improve the academic achievement, mathematical attitude and fear. The problem of this study is as follows : First, between the groups using mathematical modeling and a traditional textbook teaching academic achievement groups showed that there is a difference? Second, between the groups using mathematical modeling and a traditional textbook teaching mathematics between groups showed that there is a difference of mathematical attitude and fear? Third, what are the lessons for the students' responses using mathematical modeling?

초등학교 인공지능(Artificial Intelligence, AI) 교육은 학교급별 특성과 수준을 고려하여 놀이 및 체험 활동 중심으로 계획되고 있다. 그러나 교육 현장의 수요 및 AI 리터러시 연구에서 AI 개념의 지도 필요성이 제시되고 있다. 초등학생에게 어렵고 생소한 AI 개념을 교육하기 위해 학습자의 발달 특성을 고려한 교수학습 전략이 필요하다. 선행조직자는 개념 지도 시 학습자의 인지적 부하를 줄일 수 있는 효과적인 교수학습 전략 중 하나로 이미 초등학생을 위한 인공지능 교재에 널리 사용되고 있다. 그러나 교재 분석 결과 선행조직자는 학생별 경험과 양육환경의 차이로 인해 선행조직자로서 기능하지 못할 가능성이 있다. 이를 해결하기 위해 본 연구는 초등학교에 널리 활용될 수 있는 선행조직자를 초등 교육과정에서 추출하여 AI 교육 프로그램을 개발하였다. 본 프로그램은 초등학교 5~6학년 AI 교육 내용 기준에서 AI 개념 요소를 추출하여 초등학교 1~4학년 교과 교육과정에서 선행조직자를 선정하였고 4차시의 교육 프로그램을 개발하였다. 본 연구를 통해 개발된 프로그램이 초등학생의 효과적인 AI 개념을 학습과 AI 리터러시 향상에 도움이 될 것으로 기대된다.

최근 컴퓨터 교육의 초점은 컴퓨터 내용학으로 소양 교육에 대한 관심이 고조되면서 컴퓨터 과학 요소 및 정보통신윤리 분야를 강화하며 소양 교육과 교과 활용교육 간의 연계를 통하여 효과적으로 교육 목표를 달성할 수 있도록 하였다. 이에 따라 일선 학교에서 컴퓨터, 컴퓨터 통신, 멀티미디어, 인터넷 등의 첨단 정보 매체를 교수 학습에 어떻게 활용할 것인가에 대한 관심을 넘어 정보 교육 본질적인 관점에서 교육 방법을 찾고자 노력이 고조 되고 있다. 본 연구에서는 초등학생들에게 지도하기 어렵고 학생들이 이해하기 힘든 컴퓨터과학에 기본이 되는 컴퓨터 내용학 중 자료구조의 검색과 정렬 중 정렬 알고리즘에 대해 교수 학습방법을 설계해 이를 지도해 보고 이러한 학습내용이 초등학교 학생들에게 효과적으로 학습되는 모형을 적용하여 실효성과 이해를 높일수 있으리라 기대한다.

If students can use mathematics to solve their problems and learn the mathematical knowledge through it, they may think mathematics useful and valuable. This study is for the teaching through problem solving in mathematics education, which I consider in terms of the problem-based learning and mathematical modeling. 1 think mathematical modeling is applied to teaching mathematics as a problem-based learning. So I developed the teaching model, and showed the example that students learn the formal and hierarchic mathematics through mathematical modeling.

A new teaching-learning method is needed to improve creative problem-solving ability of the gifted students at mathematics. In response to this demand, I applied mentor-project studying to the mathematically gifted class students of Chungnam Science High School. The purpose of this monograph is to analyze in what situations they demonstrated mathematical creativity and whether the interactions among the gifted in the process of studying were of great help toward improving creativity. The effectiveness of mentor-project studying was especially verified by the analysis of creative problem-solving test results.

The research aims to provide information about the most applicable education-method by assessing learner's objective and condition, and also by searching case studies. Even though education system is introduced in various web-sites, questions about which system being most appropriate for the learner has not been answered. Therefore, instead of only providing education contents, this research paper is to create a system that contains information about academic contents, education templates, reuse of abundant educational resources and an education system specified based on the level of the learner.

This study aims at developing and evaluating the cohousing teaching/learning plan for middle and high school. The plan was developed into 5 stages such as data collection and analysis, design, development, implement, and evaluation_ It was composed of 3 lessons with various teaching materials; the concept and necessity of cohousing, spatial composition, and making a cohousing village as the main theme. The 3 home economics teachers carried out the plan for 28 classrooms (1125 students) in 2 middle and I high school, during 23th, Aug., to 17th, Sep. 2010 in Kyunggido. The high level of understanding, learning processes, interest, satisfaction with the class reported by the students showed that the plan might be adequate to both high and middle school students. The teachers carried the lessons reported the similar positive responses to the plan with some suggestions to increase teaching hours, prepare class appliances, and prepractice the teaching materials.

Open education is carried out and studied in both phases of theory and practice in Korean elementary schools in these days. 1 introduced three open teaching and learning methods which we can use practically in elementary school mathematics education. They are the teaching and learning by open-end-approach, From problems to problems and Problem posing. First, I illustrate each meaning of three teaching and learning methods. Next, I presented the concrete plans of each teaching and learning method, and exhibited some examples of students' own works.
