웹의 장점을 활용하기 위한 수학교과 교수-학습 자료들은 이미 많이 개발되어 있으나 수학교과 자료에서 사용하는 수식이 대부분 수식 자체가 아닌 그림 형태로 표현되어 있어 수식의 계산이나 검색, 재사용 등 다양한 활용이 불가능하였다. 이를 극복하기 위하여 수식 표현을 위한 마크업 언어인 MathML이 개발되었다. 본 논문에서는 수학교과 ICT 활용 교육에서의 교재 개발, 교수-학습 도구 개발, 그리고 정보교환을 위해 MathML을 활용할 수 있는 방안을 제시한다. 교재 개발에 있어서 MathML을 이용하는 것은 수식의 수정을 편리하게 하고 재사용을 가능하게 한다. 그리고 MathML을 표준으로 사용하는 교수-학습 도구들은 수식과 수학적 개념간의 연결을 강하게 해 주고, 교사들이 이와 같은 도구들을 보다 쉽게 재구성하여 수업에 활용할 수 있도록 해 준다. MathML을 이용한 수식을 사용할 수 있는 게시판은 교사와 학생간의 정보 교환을 활발하게 하고, 이를 이용한 $\ulcorner$웹토론하기$\lrcorner$와 같은 다양한 형태의 ICT활용 수업을 가능하게 한다.

This research aims to analyse implementation effects of the Real mathematics Education(RME) in the high school probability and statistics For this aim, two research questions are estabilished as fellows. (1) Is there any improvement of mathematical achievement in the class by RME's lecture than in the class by the mathematics text's lecture ? (2) Is there any improvement of mathematisation level in the class by RME's lecture than in the class by the mathematics text's lecture ? Before answering the above research questions, RME.`s lecture notes and ordinary lecture notes are developed based on the learning principles of the RME and mathematics textbook respectively. Two classes are randomly chosen from a high school located at midium size city and assigned as the experimental group and the control group respectively. The 20 hours of the RME's lecture notes is administerd to the experimental group and the 20 hours of the odinary lecture notes is administerd to the control group. It is shown that the class by RME's lecture is more effective in both of the mathematical achievement and the mathematisation activity than the class by the ordinary lecture. Hence, it is urged from the result of this research that RME's context will be developed and the RME's lecture will be implemented in the other field of high school mathematics.

시대적 흐름과 정부의 정책 시행 노력에도 불구하고 수학학습에 어려움을 호소하는 학생들이 많이 늘어나고 있다. 이를 반영하여 수학교육에서 수학학습부진아와 관련된 연구가 많이 시행되었다. 하지만 이러한 연구들의 대부분은 수학학습부진아의 원인을 밝혀내거나 교수학적 처치를 시행하고 그 효과를 알아보는 실험연구가 대부분이었다. 따라서 본 연구에서는 학위논문 및 학술지 논문 49편을 메타분석하여 수학학습부진에 대한 교수학적 처치가 학업성취도 향상에 얼마나 큰 효과크기를 갖는지 분석하였다. 이러한 분석의 결과 수학학습부진아에게 교수학적 처치는 전반적으로 중간 정도의 효과크기를 갖는다는 것을 알게 되었다. 또한 여러 중재요인을 분석하여 어떠한 환경에서 가장 큰 효과를 거둘 수 있는지에 대한 제안점도 얻을 수 있었다.

본 연구에서는 현실주의 수학교육 이론을 바탕으로 '비율그래프' 단원을 재구성한 수업이 학생들의 수학 학업성취도와 수학적 성향에 어떤 영향을 주는지를 알아봄으로써 교실 수업을 개선하기 위한 것이다. 연구 대상은 6학년 학생 68명(실험반 34명, 비교반 34명)이었으며, 수업은 MiC 교재를 참고하여 재구성한 프로그램을 8차시에 걸쳐 실시하였다. 본 연구를 통해 얻은 결론은 다음과 같다. 첫째, 현실주의 수학교육론에 근거하여 재구성한 교재를 활용한 수업이 학습자의 수학 학업성취도 향상에 긍정적인 영향을 미치는 것으로 확인되었다. 둘째, 현실주의 수학교육론에 근거하여 재구성한 교재를 활용한 수업이 학습자의 수학적 성향에 긍정적인 영향을 미치는 것으로 확인되었다.

본 연구에서는 의사소통 중심의 수학 쓰기 학습 전략을 활용한 수업이 학생들의 수학 학업 성취도와 수학적 성향에 어떤 영향을 주는지 알아보고자 하였다. 그 목적을 달성하기 위하여 동질성이 검증된 실험집단과 비교집단을 선정하여 실험집단에는 자신의 생각과 느낌 쓰기, 문제해결 과정쓰기, 개념 설명쓰기 등 3가지 유형의 의사소통 중심 수학 쓰기 학습 전략을 활용한 수업을 하고, 비교집단에서는 교과서 및 지도서에 준한 일반 수업을 진행하였다. 그 결과 비교집단에 비교하여 실험집단의 학생들의 수학 학업 성취도가 유의미하게 향상되었으며 수학적 성향에도 긍정적인 영향을 준 것으로 나타났다.

Today the high school mathematics lesson has an effect on the scholastic achievement internationally, but fails to lead to the interest in the mathematics which stimulates the intellectual curiosity. Due to this, 2015 revised curriculum includes the effort to improve the emotional aspect of mathematics positively. It is needed that the teaching method through discussion and debate must be introduced to accomplish the objective of the mathematics in 2015 revised curriculum focused on the improvement of the ability and attitude to solve the problems creatively by increasing the mathematical communication skill of the students. The purpose of this study is to investigate the effect of mathematical essay-typed lesson focused on discussion and debate on the mathematical disposition and attitude of high school student. The findings from this study provided that the essay-typed lessons focused on discussion and debate improved the subject students' mathematical achievement and disposition and attitude, but it is not significant change.

Recently, as deep learning technology has developed, various deep learning technologies have been introduced in handwritten recognition, greatly contributing to performance improvement. The recognition accuracy of handwritten Hangeul recognition has also improved significantly, but prior research has focused on recognizing 520 Hangul characters or 2,350 Hangul characters using SERI95 data or PE92 data. In the past, most of the expressions were possible with 2,350 Hangul characters, but as globalization progresses and information and communication technology develops, there are many cases where various foreign words need to be expressed in Hangul. In this paper, we propose a model that recognizes and combines the consonants, medial vowels, and final consonants of a Korean syllable using a multi-label classification model, and achieves a high recognition accuracy of 98.38% as a result of learning with the public data of Korean handwritten characters, PE92. In addition, this model learned only 2,350 Hangul characters, but can recognize the characters which is not included in the 2,350 Hangul characters

In its seventh revision to start in 2001, mathematics will have a new emphasis in the middle school curriculum. Mathematics subject is now composed of practical things in the use of mathematics. Also, the future of new generation, which has been known as the information age, places much focus on problem-solving in order to collect, analyze, synthesize, and judge various kinds informations. This demand of problem-solving ability is not only related with mathematical education but, along the entire educational process, its related to actual life. With this change of social structure, the importance of school education is increasing rapidly. Therefore, in order to grow abilities and create new knowledge, adapted this new method of self-oriented learning in groups to middle school 2nd graders for one year, the results were as follows : 1. Students developed their ability of the use of mathematical terms and signs correctly. 2. Students' mathematical knowledge and problem-solving ability improved as they had increased interest in mathematics. 3. Students' peership was enhanced through their communication and cooperative activities in groups during the class. 4. Students themselves were more willing to volunteer and participate during the class.

The purpose of this study is to provide an opportunity for better understanding and application of 2009 revised elementary school mathematics textbooks through survey data and focus group interview on structures of textbooks. First, We collect online survey results which 2333 elementary school teachers participated. Next, We interview focus group(8 teachers) about shapes of textbooks, quantity of learning contents, activities and problems for evaluation in the mathematics lessons. Storytelling is especially issued in the 2009 revised mathematics curriculum. We intensively discuss learning and teaching methods with application of storytelling textbooks; interests of students, role of storytelling textbooks etc. As results of analysis, the positive rate to use the 2009 revised textbooks is relatively high about shapes and activities of textbooks. But there is more considered about storytelling method. Storytelling may be positive on improvement of learning interests and participation of students. In order to develop these advantages, studies in relation of storytelling are more proceeded and teaching materials for teachers are required effectively in order to applicate to the elementary school.

The purposes of this study were to investigate the perceptions of teachers and students on the implementation of the intensive course completion system in mathematics courses and to provide suggestions for the improvement of the system. Five high school mathematics teachers and 338 10th graders and 87 11th graders in 2 high schools located in Gyeonggi-do participated in this study. The results of this study indicated that the intensive course completion system is more appropriate to the subjects which require less time allotment or practical exercise than mathematics courses. For better implementation of the intensive course completion system in mathematics courses, first of all, enough time allotment for teaching and learning mathematics should be guaranteed. Otherwise, the system can make students feel more burden of learning due to increase in learning volume of mathematics courses.
