기존 웹상에서의 수학식 처리 및 표기에 관련된 문제점을 보완하고, 수학식의 효율적인 표기 및 저장, 공유를 가능하게 하기 위해 W3C(World Wide Web Consortium)에서는 XML(extensible Markup Language) 애플리케이션인 MathML(Mathematical Markup Language)을 제정하였다. 본 논문에서는 MathML 문서를 보다 쉽고 효율적으로 편집할 수 있도록 사용자 중심의 다양한 인터페이스 제공을 통해, MathML 지식이 없는 사용자라도 쉽게 편집이 가능하도록 하였으며, 내부적으로는 처리속도 향상을 위해 기존 XML 파서의 기능 다수를 설계 및 구현하였다. 본 편집 시스템은 웹상에서의 MathML 사용의 보편화에 기여하고, XML을 기반으로 하고 수학식을 포함하는 문서의 효율적인 처리 등에 유용하게 사용될 것이다.

본 논문은 한글로 입력된 질의어를 이용하여 웹상의 MathML (Mathematical Markup Language) 수학식을 검색하는 시스템을 제안한다. 웹상의 수학식은 과거 이미지를 이용하여 표현되는 경우가 많았지만, 현재는 대부분 MathML과 같은 수학식 표현 마크업 언어로 작성되고 있다. 그러나 이러한 수학식을 검색하기 위해서는 해당 언어를 알고 있거나 수식 입력 툴을 이용해야 하는 경우가 대부분이기 때문에, 일반 사용자들이 수학식 검색을 하는 데에는 제약점이 따랐다. 본 연구에서는 사용자들이 전통적인 검색 방법을 이용하여 특정 마크업 언어가 아닌 일반 평문으로 작성된 질의어를 입력하여 수학식을 검색 가능 하도록 하기 위해, 평문 질의어를 MathML 표현으로 변환시키는 방법을 사용한다. 질의어로 입력될 수 있는 다양한 수학식 표현을 미리 구축한 사전을 이용하여 MathML 표현으로 변환하는 간결한 기법만으로도 MRR 0.495 의 높은 성능을 얻을 수 있었다.

This study was performed in part with the task to find measures to improve the defining characteristics of feelings, value, interest, self-efficacy, and others aspects in regards to learning math among elementary and middle school students. For this study, it was essential to understand the appropriate questions that are needed to be asked during a consultation at a math clinic, for students that are having a hard time learning math. As a method for performing this study, the content of scheduled counseling over 2 years from a math clinic were collected and the questions that were given and taken were analyzed in order to figure out the types of questions needed in order to effectively examine students that are facing difficulty with learning math. The analysis was performed using Grounded theory analysis by Strauss & Corbin(1998) and went through the process of open coding, axial coding, and selective coding. For the paradigm in the categorical analysis stage, 'attitude towards learning math' was set as the casual condition, 'feelings towards learning math' was set as the contextual condition, 'confidence in one's ability to learn math' was set as the phenomenon, 'individual tendencies when learning math' was set as the intervening condition, 'self-management of learning math' was set as the action/interaction strategy, and 'method of learning' was set as the consequence. Through this, the questions that appeared during counseling were linked into categories and subcategories. Through this process, 81 concepts were deducted, which were grouped into 31 categories. I believe that this data can be used as grounded theory for standardization of consultation in clinics.

A Bayes estimator of the scale parameter in an exponential distribution will be considered by a LINEX error, then the risk of the Bayes estimator using a LINEX loss will be compared with that of a Bayes estimator using a square error.

In teaching statistics in the secondary school, most math teachers do it and students enjoy it well before 11th grade. But, both of teachers and students feel statistics hard at 11th grade, which has been contained permutations, combinations, random variables, probability distributions, hypotheses and tests for normal distribution. In this study, we explore the efficient teaching methods of statistics for math teachers and also find many students enjoying it.

Math classes has been regarded as an independent area of a teacher and his/her students of a particular class. In Recent discussions about the professional development of teachers, for the improvement of practices, the point of view of that the community of teachers must work together is spreading. What are the considerations in organization and operation of learning communities for professional development of teachers? In this study, we analyzed the case of the learning community of math teachers in a Science Academy for the purpose of improving math classes to promote the participation of learners. Research results show that teachers share the principles and goals of mathematics teaching through the learning community. Also, through participation in learning communities, the members were practicing the lessons improved by reflection on the lessons of his/her and their colleagues. These results provide implication that it is important to provide opportunities for objectifying his/her classes through the learning community for a substantial improvement in math classes.

The study focuses on what to consider and do for the improvement of math education of Korean Universities by comparing freshmen and seniors of department of math education in their beliefs in mathematics and math. education. The major comparing topics in the beliefs are composed of perception of mathematics as a science, learning methods of mathematics, teaching methods of mathematics, and roles and qualifications of math. teachers. The results of the study show that junior students tend to be more positive in their beliefs, especially in math education area than that of mathematics, compared to the freshmen. It implies that how important the role of topics covered in math education during college years is for changing the future teachers' beliefs in math and math education more positively. The supposed influencing contents of the curriculum of math. education are composed of learning reflection method based on problem-based learning, understanding mathematics as originated from the real world, mathematical pedagogy, text analysis, practice in classroom, and understanding various concepts in math. education area.

The purpose of the study were to analyze MathThematics textbooks and Korean middle school mathematics and to investigate the difference among the textbooks in the view of mathematical communication. According to the results, the textbook developers made a variety of efforts to develope students' mathematical communication ability. Students were encouraged to communicate with others about their mathematical ideas or problem solving processes in words or writing by means of discussion, oral report, presentation, journal, etc. MathThematics textbooks provided student self-assessment opportunity to improve student performance in problem solving, reasoning, and communication. In communication assessment, students can assess their use of mathematical vocabulary, notation, and symbols, the use of graphs, tables, models, diagrams and equation to solve problem and their presentation skills. The assessment activities would make a positive impact on the development of students' mathematical communication ability. MathThematics textbooks provided a variety of problem situation including history, science, sports, culture, art, and real world as a topic for communication, however, the researcher found that some of Korean textbooks depends heavily on mathematical problem situations.

In this study, we made the analysis of the relation with mathematical tests and scholastic attainments of gifted students using the results of entrance end comprehensives exams and so on in science education center for gifted youths. For this, we firstly made an analysis of correlation between math and math, math and science and science and science using the test results. And then, we interviewed four students. From this, we found followings. First, in every assessment except for those carried out during the semester in the center, we saw a very low or negative correlation between the students' grades in math and that in science. Second, in contrast to the correlations among other assessments, a high correlation of the students' grades in math and science appeared in regard of the assessments carried out during the semester in the center. Third, correlations between the grades of assessments in mathematics were much lower than that in science. Fourth, many students thought the assessments in the center were not as valuable as those in their schools, which are referred to in getting into a school of high grade. So some of the students who gained excellent grades showed a relatively low achievement. Fifth, students in the center regarded a vigorous communication and inquiry learning on enriched themes as the biggest merit of attending the center.
