본 연구에서는 중학교 수학·과학 영재학생을 대상으로 하는 원격교육 자료를 개발하고 원격교육을 실시하여 학생의 반응을 분석하였다. 원격교육은 4가지 유형 - 원격강의용 프로그램을 이용한 강의형, 시뮬레이션 프로그램을 통한 실습형, 토론식 과제해결형, 문제해결형 - 으로 개발하였고, 학생의 반응은 8개 영역 - 자극, 난이도, 구성, 학습환경, 참여, 상호작용, 학습결과, 다른 수업과의 비교 - 에서 조사되었다. 조사 결과, 난이도는 모두 높게 나타났지만 원격교육이 학생에게 주는 자극은 모두 긍정적인 것으로 나타났고 개발한 원격교육이 창의성, 논리적 사고, 지적능력, 정보탐색 능력 향상에도 도움이 된다고 응답 하였다. 영재학생들은 학습내용을 상세하게 설명해 주는 방식보다는 적절한 안내 후에 스스로 실습해 보게 함으로써 인지적인 도전을 유발하게 하는 것이 참여도를 높이는 것으로 나타났다. 또한 토론식 과제해결형과 같이 토론을 유도한 경우에서만 상호작용이 있는 것으로 나타났다.

The purpose of this paper was to develop manipulative materials to teach the angle concepts and construct a teaching-learning program by using that. Furthermore, this study analyzed how does the program affect students understanding of the angle concepts. To check the effects of learning activities with manipulative materials on the understanding of an angle concepts, applied observation during class and write a mathematics journal writing, a description of students impressions at the end of the class and analyzed before and after test paper. We find that students approached the subject more friendly and knew well about the mathematical concepts by using materials. Furthermore, this activity helped that way to solve add and subtract of the angle, estimate ability, round angle concept, positive response in mathematics learning.

In recent years, an increasing number of viewpoints hold that students should be engaged in a learning environment where understanding and knowledge transfer take place. This study introduces Mathematics Created by You (MCY)-mentoring program, which allows students to construct artefacts that are required to learn. This program is online-based and so can be shared by several people and mathematics leaning takes place through interactions within this carefully designed environment. Also, MCY intends to provide students a series of sequential activities related to creative play, creative learning and creative inquiry based on a Constructive and interactive environment. Furthermore, a creative activity- constructing a creative product using building blocks- was presented as an example. Finally, we investigate the pedagogical implications and suggest directions for the further development.

This research has an intention of developing a professional development program. We proposed an alternative mathematics teacher training model based on the situated learning theory, community of practice, and reflective practitioner. The developed mathematics teacher professional development program recruited participation unit that was consisted of 3 or 4 teachers in same school and total of 28 teachers from 9 schools. Also, there were 18 mentors to support each school. In this sense, it can be called multi-tired teacher community professional development program. Through the program, the teachers improve their teaching competency. Also, the operation ability of teacher learning community was improved. Learning community culture has been formed in each school. It shows ability that the explorative learning community can be operated voluntarily although the program finished. Furthermore, community shared corporate responsibility about open class. They recognize open class as a new method to improve community teaching ability than a tool to evaluate individual teaching ability.

Nowadays the use of computer has a tendency to be being increased in classroom. Also, Many mathematics teachers are attempting to use computer efficiently in classroom. Computer has unique functions such as graphic, animation, and error correction. As graphic and animation can make the content of mathematics visible and make it easy for learners to study mathematics, it is desirable to develop the computer educational program and use it in teaching and learning mathematics. Especially, before concepts study on the unit of Figure or Function, the use of graphic or animation is efficient by being able to understand easily the content. The purpose of this thesis is to produce the computer program on the Movement of Figure in the unit of Equation of Figure which is in mathematics curriculum for the first grade of high school. In teaching and learning mathematics by use of this program, the educational effects are expected as follows: 1. It is expected that this program will stimulate the interest of learners by using animation and acoustic (sound) effect and so learners' voluntary and active thinking activity will be shown. 2. It will be helpful to form exact concept because it is possible to understand intuitively the basic concepts on the Movement of Figure by using graphic and animation. 3. It is expected that the repeated study of this program already designed will remove the fear of incomplete parts and help review them. 4. It is possible to change from teacher-centered instruction, which is the blind point of recent mathematics education, to the learner-centered instruction. However, it is necessary to realize that using the educational engineering (computer) in mathematics education cannot always cause learners to study mathematics very well and that computer cannot take the place of mathematics teacher. Accordingly, computer will be treated as aids which help learners study difficult part.

This study examines the effects of reflective journal writing on the mathematics self-efficacy in reciprocal peer tutoring. Participants were 38 high school students in Gyeonggi province who attended at a summer intensive mathematics course for 4 weeks. This study used a mixed method. SPSS 21.0 program was used to analyze the quantitative data, and the interviews, observational journals and reflective journals of 6 students were used to analyze qualitative data. According to the results, all the subcategories of mathematics self-efficacy, - mathematics problem-efficacy, mathematics success-efficacy, mathematics learning-efficacy, and mathematics subject-efficacy - improved except mathematics occupation-efficacy. In case of mathematics success-efficacy and mathematics problem-efficacy, students revealed the greatest improvement. In conclusion, reflective journal writing in reciprocal peer tutoring could be suggested as a treatment program to improve students' mathematics self-efficacy.

본 연구에서는 지역아동센터라는 경제적 빈곤과 교육의 사각지대에 놓인 저소득층 아동 청소년의 자기 주도적 수학학습 능력을 함양하기 위한 방법으로 EBS 콘텐츠의 활용이 저소득층 아동 청소년의 자기 주도적 수학학습 능력을 함양하는데 어떻게 영향을 주는가를 알아본다. EBS 동영상과 학습자의 수준에 맞춘 수준별 학습 자료를 이용한 자기 주도적 수학학습 프로그램이 청소년들에게 수학에 대한 적극적인 학습 태도를 갖게 해 주며, 수학 개념 형성을 용이하게 해 주며, 의사소통능력과 인격함양에 도움을 주며, 수준별 학습을 강화시켜 주고 문제해결력을 신장시키고 스스로 객관적 평가를 할 수 있도록 하여 자기 주도적 수학학습에 긍정적 영향을 줄 수 있다는 것을 본 연구의 과정과 내용 및 결과물을 통하여 확인하고자 한다.
