The purpose of this study was to compare and analyze changes to the middle school mathematics textbooks of third mathematics curriculum period and seventh mathematics curriculum period. This study put the math curricula from the third to the sixth one in third mathematics curriculum period as those math curricula witnessed the maintenance of industrial society paradigm. And then it put the math curricula from the seventh one to current the 2009 revised mathematics curriculum in seventh mathematics curriculum period as the knowledge-based information society paradigm has continued throughout those math curricula. Based on those period categories, We compared and analyzed changes of the middle school math textbooks. For the comparison and analysis of math textbooks between the two periods, this study set the unit organization system, unit goal, task type and content development approach as analysis elements in the unit of 'Nature of Figures' in the second grade math textbooks for middle school. As a result of the research, it was confirmed that the textbooks of the two periods had many changes in the unit organization system, but the unit goal, task type, and content development approach stayed in low level goals and task type that require conceptual and procedural.

The purpose of this study is to present the direction of elementary school AI education by analyzing cases of classes related to AI education in actual school settings. For this purpose, 19 classes were collected as elementary school class cases based on AI education. According to the result of analyzing the class case, it was confirmed that the class was designed in a hybrid aspect of learning content and method using AI. As a result of analyzing the achievement standards and learning goals, action verbs related to memory, understanding, and application were found in 8 classes using AI from a tool perspective. When class was divided into introduction, development, and rearrangement stages, the AI education element appeared the most in the development stage. On the other hand, when looking at the ratio of learning content and learning method of AI education elements in the development stage, the learning time for approaching AI education as a learning method was overwhelmingly high. Based on this, the following implications were derived. First, when designing the curriculum for schools and grades, it should be designed to comprehensively deal with AI as a learning content and method. Second, to supplement the understanding of AI, in the short term, it is necessary to secure the number of hours in practical subjects or creative experience activities, and in the long term, it is necessary to secure information subjects.

This study investigates the contents of programming education in elementary information education textbooks in Busan and Zhejiang. Two textbooks identify the contents of elementary school information education textbooks on setting goals of programming education, selecting educational programming languages, and selecting and developing contents of programming education. Textbooks in the two regions are designed to select programming languages for elementary school levels and to select creative learning topics to help learners learn programming in the process of solving problems themselves. The textbooks identified in this study are designed so that learners can learn programming naturally in the process of solving problems.

Teacher librarians' teaching practice is a major training course to strengthen their expertise. The purpose of this study is to propose more systematic program for effective teaching practice of teacher librarian in Korea. For this, the course contents of teaching practice were derived from the teacher librarians' expertise standards published by Korea Institute for Curriculum and Evaluation. And the survey was carried out to decide which contents are regarded as more important or less. According to four selection criteria and the result of survey, 13 contents were selected. After all, this study proposed teacher librarians' teaching practice program consisted of practice objective, method of guidance, practice material and attentive point.

From 2011, newly developed Information textbook will be given to high school students. This research investigates contents of the new Information textbook and attempts to offer improvement of the book, which were compiled according to the 2007 Revised Curriculum. This thesis aims to make a comparative analysis of the contents and structure of six Information textbook which passed the screening. The structures of six textbooks were examined under four sections, which are overall structure, relative importance in the textbook, development method, and evaluation type. Moreover, for analyzing the contents, the research investigated the number of the major concepts that are dealt in the textbooks. The results show that there are too many difficult concepts for high school students and reveals that there are big difference in the contents and construction among textbooks. This research suggests how the textbook should be revised in the light of the contents, construction, terminology, and practical training.

홈 네트워킹 시대의 도래에 대한 낙관적인 견해 보고서가 나날이 증가하고 있다. 늦어도 3∼4년 후에는 가정내의 모든 전자제품들이 하나의 관리시스템을 통해 통제가 가능해지고, 디지털 TV를 통한 쌍방향 커뮤니케이션이 익숙해질 것이라는 내용들이다. 하지만 본격적인 홈 네트워킹 시대가 오기 위해서는 여전히 많은 선결과제들이 남아 있다. 세계적으로 많은 기업들이 표준화 작업에서 주도권을 확보하기 위해 서로간의 견해차이를 줄이지 못하고 있고, 전력선 네트워크와 무선네트워크 기술 역시 우리가 기대하는 홈 네트워킹 시대를 가져오기에는 아직 부족한 듯 하다. 최근의 홈 네트워킹 기술 현황과 향후 전개될 지역별 시장전망을 살펴본다.

지난 해 5월 정부가 그룹 VAN을 허용함에 따라 그룹사 정보처리 네트웍화의 길이 열렸다. 이로써 우리 나라에도 민간 VAN이 시작되었다. 민간 VAN은 이미 선진 각국의 주요 기업에 의해 산업화되어 급성장하고 있고, 국내에서도 근래들어 그룹사들에 의해 경영정보 공동활용과 새로운 유망 사업 분야로서 구상되기에 이르렀다. 이렇게 도입 욕구가 팽배된 적절한 시기에 민간 VAN이 허용됨에 따라 럭키금성을 비롯한 6개 그룹사가 이에 참여 하고 있는 가운데 제도상.기술상의 제반 문제점들이 도출되고 있다. 그룹 VAN 진출 기업들을 회원으로 하고 있는 본 협회는 국내 민간 VAN 사업의 활성화를 위하여 구랍 28일 문제점들의 시정을 정책 당국과 공중통신사업자, 그리고 진출기업에 건의 했다. 그 내용을 전개한다.
