Polishing a die that has free-form surfaces is a time-consuming and tedious job, and requires a considerable amount of high-precision skill. Some workers tend to gradually avoid the polishing work because of the poor environment caused by dust and noise. In order to reduce the polishing time and cope with the shortage of skilled workers, a user-friendly automatic polishing system was developed in this research. The polishing system with five degrees of freedom is able to keep the polishing tool normal to the die surface. The polishing system is controlled by a PC-NC controller. To easily operate the developed polishing robot system, this study developed an integrated program in the Windows environment. This program consists of four modules: the polishing module, the graphic simulator, the polishing data generation module, and the teaching module. Also, the automatic teaching system was developed to easily obtain teaching data and it consists of a three dimensional joystick and a proximity sensor. The joystick is used to simultaneously drive the polishing system to an arbitrary orientation and the proximity sensor is used to obtain teaching points precisely. Also, to evaluate the stability of the driving program and the teaching system, polishing experiments of a die of saddle shape were carried out.

급변하는 사회 환경에 따라 학교교육도 다양성을 추구하고 있는 가운데 교실 내에서도 획일적인 수업이 아니라 학생의 수준에 따라 교육과정을 편성하여 운영하도록 요구되는 추세이다. 이에 본 연구에서는 초등학교 6학년 학급 내 기존의 수업방법에서 탈피하고, 개정 제7차 수학과 교육과정에서 강조하고 있는 수준별 수업을 현장에 적용하기 위해 실험집단을 상, 하 집단으로 편성하여 각 집단에 맞는 수준별 수업 프로그램을 구안하여 적용한 후, 수학 학업성취도 및 수학적 성향에 어떠한 영향을 미치는지 알아보았다. 이 연구는 개정 제7차 수학과 교육과정이 추구하는 목적을 사전에 적용하여 분석해 봄으로써 교실에서 수준별 수업의 방향을 제시하고자 한다.

New attempt has been made on Management Science (MS) education since the end of 1990s. The most distinctive feature of the new attempt is using spreadsheet program like Excel as a teaching tool for MS course. The spreadsheet program gives an excellent tool for modeling and solvina MS problems. In order to improve the pedagogical effect through using the spreadsheet program for MS course, new teaching model based on spreadsheet encompassing new course contents, effective instruction method, and examination method is needed. For this purpose, professors teaching MS should share their own teaching experiences and methods. So this paper explains remarkable functions of Excel and how to use them for the MS tools. This paper also stresses the importance of team project and case study to improve the effect of MS education through the use of Excel and presents some tips on MS education.

The purpose of this study is to develop and apply effective teaching strategies and program for the gifted-in-science. The teaching material for the gifted students was focussed on microscope. This study consists of three steps according to the enrichment triad model of Renzulli. Firstly, the gifted students investigate and express themselves for theological backgrounds, for examples, kinds, structure and use in various ways of microscope. It is to provide basic data for the effective ideas and interest which help students have the appropriate microscopic conceptions. In the second step, it contains understanding of a term and function of microscope, making of simple microscope, principle of a statue focusing and size estimation of an outline of subjects by scientific investigation activity. Lastly, it focussed on enlargement of post-learning through investigation of relationship with inter-science and experiments using microscope. Therefore, it was concluded that this study may help teachers reconsider scientific program development for the gifted or enriched students and to be successful in the teaching-learning processes.

The purpose of this article is to develop a program for teaching Type I and Type II errors in one sample. In this program, the concepts of two errors are visually explained, and the probabilities of two errors are also visually displayed as the rejection region changes or the sample size changes. Also, in this program, the power curve and the operating characteristic curve are visually displayed in terms of the parameter value of interest.

본 연구는 제 7차 교육과정이 도입되면서 수학교육에서 중요성이 증가하고 있는 구성주의 교수 학습 모형을 초등 수학영재 교육 프로그램에 적용한 결과를 분석한 것이다. 일반적으로, 영재들은 활발한 의사소통을 통하여 더 많은 지식을 구성해 나갈 수 있으며 또한 왕성한 호기심으로 스스로 문제를 해결하고 원리를 발견하고자 하는 욕구가 크다. 영재들의 이러한 특성을 살려 서로간의 의사소통과 합의를 통하여 보편적인 지식을 구성해가는, 사회적 구성주의를 그 이론적 배경으로 하고 있는 수업 모형을 바탕으로 개인적인 원리를 구성하고 발표와 질문을 통해 오류를 수정하여 보편적인 수학적 원리를 찾아가는 방식으로, 네트워크 문제와 관련된 3가지의 주제를 중심으로 구성주의 교수.학습 모형을 적용하여 학생들의 알고리즘적 사고 능력이 어느 정도인가를 분석하였다.

Purpose: The purpose of this study was to investigate the effects of an intensive teaching program on the knowledge level of MI in patients with a myocardial infarction. Method: The subjects were 47 patients with a myocardial infarction. Of the subjects 23 were assigned to the experimental group and 24 to the control group. The data were collected through a questionnaire (Lee, 1992; Nam, 1998) survey of knowledge level. The data collection was done about MI between September 15, 1999 and December 31, 2000 after hospital discharge. Data were analyzed using the SAS program and the results are as follows. Results: 1. There were no significant difference in knowledge level of the MI (P=0.621) between the two groups before the teaching program was given. 2. After 4 weeks the knowledge level about MI was significantly higher in the experimental group compared to the control group (P = 0.000). 3. After 12 weeks the knowledge level about MI was significantly higher in the experimental group compared to the control group (P= 0.000). 4. After 4 weeks the experimental group was at a higher scores of knowledge category about MI for nature of disease (P=0.000). risk factors, (P=0.000), diet (P=0.000), medication (P=0.000) exercise and daily activities (P=0.000) as compared to the control group. 5. After 12 weeks the experimental group was at a higher scores of knowledge category about MI for nature of disease (P=0.000). risk factors (P=0.001). diet (P=0.000), medication (P=0.000) exercise and daily activities (P=0.000) as compared to the control group. Conclusion: The above findings indicate that the intensive teaching program used for the experimental group in this study was effective in increasing the knowledge level about MI of the patients with a myocardial infarction.

This research has an intention of developing a professional development program. We proposed an alternative mathematics teacher training model based on the situated learning theory, community of practice, and reflective practitioner. The developed mathematics teacher professional development program recruited participation unit that was consisted of 3 or 4 teachers in same school and total of 28 teachers from 9 schools. Also, there were 18 mentors to support each school. In this sense, it can be called multi-tired teacher community professional development program. Through the program, the teachers improve their teaching competency. Also, the operation ability of teacher learning community was improved. Learning community culture has been formed in each school. It shows ability that the explorative learning community can be operated voluntarily although the program finished. Furthermore, community shared corporate responsibility about open class. They recognize open class as a new method to improve community teaching ability than a tool to evaluate individual teaching ability.
