Although many mathematical teaching/learning materials are already developed in the web, diverse utilization of this materials such as calculation, searching, or reusing of expressions are limited since the expression is actually a figure. To cope with this, MathML which describing mathematical notation was developed. In the paper, we proposed the methods of developing teaching materials using MathML, making learning assistance tools which utilize MathML, and applying MathML to information exchange community for Mathematics courses in ICT environment. Using MathML to develop a teaching material makes easy to correct and reuse the mathematical notations conveniently. Furthermore, learning assistance tools made by placing MathML help teachers reorganize and utilize these materials in the classroom as well as enhancing the connection between mathematical notations and concepts. The web-board that can make a use the mathematical notations using MathML enables the teachers and students to exchange information actively. It also helps to fulfill different types of teaching using ICT such as "discussion on the web".

Represent of mathematical formula used within system handling document that is nonstructural in existent document editing system that is used in electron document processing that use computer is represented or processed by method that is nonstructural of image or text or etc. Such mathematical formular causes relative inconvenience to readablility and reusability of document and processing and exchange of document. Therefore, document editing system is required that can overcome such nonadvantage and apply MathML mathematical formula structure on efficiently structural document. Therefore, designed and implemented that document editing system for structural document creation of XML base that can mathematical formular editing of MathML base in this paper.

본 논문에서는 Mathematical Markup Language(MathML) 형식으로 작성된 수학식 분류를 위해 필요한 자질과 성능 향상에 기여하는 자질 조합을 비교 평가한다. 이것은 MathML 형식의 수학식을 분석하기 위한 전처리 작업으로, 연산자의 모호성을 해소하기 위한 가장 기본적인 단계에 해당한다고 볼 수 있다. 실험에 사용되는 기본자질(Baseline)은 MathML 태그 정보와 연산자이고, 여기에 다른 자질들을 추가하며 가장 높은 분류 성능을 가지는 자질을 찾는 방식으로 진행하였다. 학습은 지지벡터기기(Support Vector Machine: SVM)를 사용하였고 분류하고자 하는 단원은 '수학의 정석' 책을 토대로 총 12개(집합, 명제, 미분, 적분 등)로 나누었다. 실험을 통해 MathML 문서 안에서 가장 유용한 자질이 '식별자&연산자 바이그램'인 것을 알 수 있었고, 여러 가지 자질들을 조합하여 수학식을 분류한 결과 92.5%의 성능으로 분류하는 것을 확인할 수 있었다.

Digital talking books have been developed to enhance reading experiences for reading-disabled people. In the existing digital talking books, however, it is difficult to read special contents such as math expressions, images, etc. In this paper, we define reading rules for Contents MathML. Based on this rules, we implemented a program for reading the mathematical contents of Contents MathML, using XSLT. We conducted a confirm test to prove the accuracy of the program, and an usability test to measure understanding of reading text of math expressions.

Recently, many kinds of XML based application services are widely used in internet. And the markets for mathml editor are needed for the technology combined with other text editor. We are developing a system for MathML based browser and editor for the service of internet application. MathML based browser is applicable for e-book service and many kinds of document system. This system is composed of document editing module and displaying processing module. This system is useful for the processing of MathML tag by unexperienced users with MathML syntax. Users can edit the math tag's document with ease and efficiently. Based on XML, many parser functions are optimized for the speed of document processing. This system can afford to the development of internet world.

Internet has been widely spread out and the need of convenient mathematical expression in the internet has been in need. In this paper, we discvss how MathML and JAVA have been developed for mathematical expressions in the internet. And we introduce our JAVA applet tools that adapted the object oriented programming techniques of the MathML and JAVA. Most of our JAVA toots have been developed for linear algebra course whose method can be applied to other subject as well. Then we discuss how we use those tools and output from the use of them in our class.

In this paper, we propose an authoring methodology of differentiated instruction-learning materials in mathematics course using MathML and XSLT, and give utilizing suggestions of these materials as differentiated textbook and individual learning. Incorporating MathML into instruction-learning materials, there are many advantages such that view of the materials in web browser is improved since mathematical expressions are compatible with text, and an expression can be modified in more convenient way since the expression is represented in text format not an image. In authoring of differentiated materials, the author provides one document for various levels of students. Then, each level of materials is generated from the document via XSLT transformation. This enables author-driven progress control rather than student-driven which does in previous approaches, since students don't need to select components of the material.

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.
