The purpose of this study is to analyze the contents of pi of Chosun-sanhak and organize the teaching and learning activities to help to understand the concept of pi deeply using the analysis results. The results of this study are as follows. First, Chosun-sanhak used various approximate values of pi and those were represented as the form to reveal the meaning of the ratio of radius and circumference. Second, There were the freedom of selection of the approximate values of pi suitably. Lastly, the enriched leaning about pi need to draw a distinction pi from approximate values of pi, choose the suitable approximate values of pi and compare the method of calculation of circumference and the area of circle of Chosun-sanhak and today's mathematics. In conclusion, I proposed several issues which is worth exploring further in relation to pi and Chosun-Sanhak.

최근에 들어 교육현장에서 수준별 교육의 중요성이 대두되고 있다. 그러나 적은 수의 교사로 많은 수의 학습자를 수준별로 교육하는 것은 쉽지 않은 일이다. 조별 이동이나 급간 이동으로 수준을 나누어 교육하고 있으나 변화하는 학습자의 정확한 수준 측정 및 이동이 어렵다. 또한 CAI(Computer Aided Instruction) 프로그램이 많이 보급되었지만 수업 외 시간에 학습자 스스로 반복 훈련을 통한 학습을 강조하므로 교실 수업에 적용하기는 어렵다. 따라서 본 논문에서는 이러한 문제점을 해결하기 위하여 수업시간 교사의 지도하에 웹을 기반으로한 교수-학습을 통해 각 학생들의 수준을 평가한 후 수준에 맞는 학습과 보충 및 심화학습이 이루어질 수 있는 웹기반 수준별 교수-학습 시스템을 설계하고 구현하였다.

Geometry having long history of mathematics have important role for thinking power and creativity progress in middle school. The regular polygon included in plane geometry was mainly taught convex regular polygon in elementary school and middle school. In this study, we investigated the denotation's extension of regular polygon by mathematical basic knowledge included in school curriculum. For this research, first, school mathematical knowledge about regular polygon was analyzed. And then, basic direction of research was established for inquiry. Second, based on this analysis inductive inquiry activity was performed with research using geometry software(Cabri Geometry II). Through this study the development of enriched learning material and showing the direction of geometry research is expected.

This study aimed to explore the geo-educational value of Deokmyeong-ri in Goseong-gun, Gyeongsangnamdo, through field research. The study area comprises well-exposed outcrops, which can be used as field sites during field trip for studying sedimentary structures (normal grading bedding, cross bedding, ripple, and desiccation crack), coastal depositional environments (coastal cliff, shore platform, and gravel beach), basic principles of relative dating (unconformity, fault, intrusion, and xenolith), and columnar joints. This study evaluated the field sites based on the achievement standards and textbooks used in the science curriculum. The field sites have a high educational value because they exhibit typicality, as mentioned in the textbook, and provide study materials for enrichment learning. Furthermore, Deokmyeong-ri Area has well-developed tourist and educational infrastructures; thus, it is a safe place for geological education.

The purpose of this study is to analyze the actual realization of the opportunity to learn given to students by examining students' cognition for enrichment mathematics textbook tasks' levels of cognitive demand. First, we analyze characteristics and limitations based on the theoretical framework. Second, we examine students' cognition about the distribution of the mathematics textbook tasks' levels of cognitive demand. And we analyze how the opportunity to learn actually work. Third, in the sense that enrichment textbooks are textbooks for science school students, we analyze whether the opportunity to learn for gifted is offered. The conclusion is as follows: First, with respect to levels of cognitive demand, PNC tasks account most. Second, students also cognize that PNC tasks account most. Third, tasks for gifted are not offered and students also cognize that opportunity to learn for gifted is lacked.

제 7 차 교육과정에서 경제지리 과목이 심화 선택 과목으로 새롭게 설정되었다. 그러나 제 6차 교육과정 한국지리 과목의 경제지리 교육내용을 단순 확대.심화시켜 구성하였기 때문에, 그 동안의 비판과 문제점을 해결하지 못하고 있다. 지리교육에서 경제 지리교육내용의 선정 및 조직 바법은 산업별 분류방법, 주제 중심방법, 경제과정 중심방법으로 분류할 수 있는데, 기존은 교육과정은 산업별 분류방법을 근간으로 하고 있다. 본 연구에서는, 공급자의입장에서 나열적으로 교육내용을 선정.조직하고 있는 기존 방법의 문제점을 개선하고, 실생활에서 학습의 유용성을 확인시켜 학습자의 관심과 흥미를 갖게 하며, 다양한 형태의 교수-학습 활동이 가능하도록 하면서, 심화 선택 과목의 특성을 살릴 수 있는 경제 지리 과목의 교육내용 선정 및 조직 대안으로 지역문제 중심방법을 제안한다.

Providing gifted education should be based on the principle of differentiation, that is, paying close attention to the individual characteristics of the gifted. The gifted are known to be the fast learners with autonomous studying ability and high levels of thinking and creativity, which certainly differentiate them from the ordinary others. Thus, the program for the gifted should fundamentally differ from other general programs. The need for gifted education is growing as our society has turned into the knowledge-based society. Fortunately, on December 28th, 1999, a law in favor of gifted education was passed. According to the law, gifted education will be actively provided under the government's support from the year 2002. In this context, this study is intended to search for the model of developing instructional materials for the gifted. The output materials of this study are to be used in gifted schools which will be built in the near future. The curriculum for the gifted consists of three parts: basic curriculum, in-depth curriculum, and optional curriculum. The learning and instructional materials developed in this study are to be used for the in-depth curriculum. In order to develop the materials, various theoretical models related to gifted education were reviewed. Finally, a theoretical model was developed. On the basis of the model, several instructional materials are developed and the possibility of application are considered.

The purpose of this study is to develop the enrichment curriculum connected to a Revised Version of 7th National Informatics Curriculum in Middle School for gifted students in IT education. This study uses a Delphi Method to develop a curriculum which is comprised of educational objectives, educational contents, teaching-learning method and educational evaluation. This study carried out a three-round delphi survey in 'The problem-solving method and its procedure' field from grade 1 to grade 3. In this study, first, the responses of the experts about educational objectives, educational contents, teaching-learning method and educational evaluation of each grade were analyzed. Second, organized items were designed. Finally, important items were selected by statistics.

This study was conducted to evaluate the effects of simulation integrated with problem based learning in terms of critical thinking, problem solving, learning motivation according to Myers-Briggs type indicator(MBTI) personality type in advanced nursing course students. This study was a non-equivalent control posttest only design. Students were all enrolled in advanced nursing course which included 1) 6 weeks problem based learning 2) 5 weeks simulation integrated with PBL and debriefing. Total 19 students' data were collected and analyzed on SPSS win 21.0. The results showed students who have out patients working experience were significantly higher learning motivation(${\chi}^2=9.85$, p=.044), no experienced simulation were significantly higher critical thinking(${\chi}^2=4.44$, p=.035) and as temperament of MBTI, NT types were significantly higher on critical thinking(${\chi}^2=8.53$, p=.036). Students show various personality types and it might be impact on attitudes of learning and the results. Thus we need to understand their diversity and consider it to apply teaching methods on nursing education.

2000년 1월 28일에 영재교육진흥법이 제정 ${\cdot}$ 공포되었고, 2002년 4월 18일에 영재교육진흥법시행령이 공포됨에 따라 본격적으로 공교육 차원의 영재교육이 실시되고 있다. 그에 따라 영재교육의 목적을 이룰 수 있는 적절하고 다양한 교수-학습 자료의 개발이 시급한 쟁점으로 부각되었고, 비로소 2002년 6월 15개 시${\cdot}$도 교육청이 한국교육개발원에 위탁해 영재학급과 영재교육원에 투입할 학년별 50차시 분의 초등학교 4${\sim}$6학년 영재 심화 교수-학습 자료를 개발하게 되었다. 하지만 영재교육의 내실을 기하고 활성화를 위해서는 좀 더 다양한 교수-학습자료가 지속적으로 개발되어야 하며 많은 시도가 있어야 한다. 따라서 본 연구에서는 영재학급용으로 개발된 심화 교수-학습 자료에 제시되지 않은 내용을 중심으로 영재학급에 활용할 수 있는 초등학교 5${\sim}$6학년 수학 영재교육을 위한 학습자료를 개발하고자 한다.
