Teach pendant is the most widely used means of robot teaching at present. Despite the difficulties of using the motion command buttons on the teach pendant, it is an economical, robust, and effective device for robot teaching task. This paper presents the development of a force/moment direction sensor named COSMO that can improve the teach pendant based robot teaching. Robot teaching experiment of a six axis commercial robot using the sensor is described where operator holds the sensor with a hand, and move the robot by pushing, pulling, and twisting the sensor in the direction of the desired motion. No prior knowledge of the coordinate system is required. The function of the COSMO sensor is to detect the presence f force and moment along the principal axes of the sensor coordinate system. The transducer used in the sensor is micro-switch, and this intuitive robot teaching can be implemented at a very low cost.

The purpose of this study is to compare learners' view on Korean and native teachers of English with regard to competence of teaching skills. A total of 166 high school students attending the same high school in Korea participated in a questionnaire survey. The students were asked a series of questions about their five Korean teachers of English and three natives. The analysis of the results indicates that the learners believed Korean English teachers would be better in teaching vocabulary, grammar and reading than native English teachers. The learners answered native English teachers would be better in teaching speaking, listening, and writing. In the areas of the accuracy of classroom language, the level of teacher-centeredness, and the amount of cultural information given in a classroom, there were no significant differences in the learners' responses between Korea and native teacher of English. By recognizing the differences of the learners' views on two different types of ELT teachers, we suggest that it would be beneficial for learners if we would utilize their views in designing and administrating a team-teaching program.

교사의 수업자신감은 학생들의 성취도 향상에 영향을 줄 뿐만 아니라 교사의 직업 생활의 질을 높이는 데도 중요한 변인임에도 불구하고, TIMSS 결과에서는 다른 국가에 비해 우리나라 중등 수학 교사의 수업자신감이 낮은 것으로 나타났다. 교사들의 수업자신감을 높이기 위한 방안을 탐색하고자 본 연구에서는 교사경력, 수업준비도, 교사협력, 수업제한의 네 가지 맥락변인이 우리나라 중등 수학 교사의 수업자신감에 미치는 영향과 이 변인들이 수업자신감의 변화에 대해 갖는 설명력을 살펴보았다. 분석 결과 네 가지 예측 변인을 투입했을 때 수업준비도, 교사협력, 수업제한의 세 가지 변인이 수업자신감에 영향을 주고, 수업자신감의 변화에 대한 설명력의 경우 다른 변인이 합성되지 않은 수업준비도의 고유 효과가 가장 큰 것으로 나타났다.

본 논문은 수업을 위한 수학적 지식과 수업의 질에 대한 상관관계를 보고하는 연구이다. 선다형 평가 문항 유형의 설문지를 이용하여 교사들의 수업을 위한 수학적 지식을 수집하였고, 촬영된 그 교사들의 수업을 수학 수업 분석 도구를 이용하여 수업의 질을 평가하였다. 두 점수들의 상관관계를 통계적으로 분석하여, 유의미한 양적 상관관계가 있음을 보고한다. 또한, 수집된 수업 영상과 교사들의 인터뷰 자료의 분석을 통해 수업을 위한 수학적 지식이 중재하지 못하는 수업의 질과 관련된 요소를 찾아내었다. 이러한 결과를 기반으로 수학 교사 교육에 대해 논의한다.

In the past half century little effort has been made for the improvement of teaching and learning statistics compared with other parts of school mathematics. But recently data analysis has begun to play a prominant role in the national reform efforts of mathematics curricula in the United States of America and the United Kingdom. In this paper we overview modern statistical thinking differed from mathematical thinking and examine the problems of current old-style teaching of statistics. And, we discuss the current data handling(or data analysis) emphasis in the national curriculum of mathematics in the countries mentioned above. We explore the reform direction of statistics teaching; changing the philosophy of teaching statistics, teaching real data analysis, emphasis of using computer, and teaching statistical inference not as mathematics but as intuitive data-centered approach.

Complement is a special grammatical phenomenon in Chinese. There is no complement in Korean, so complement teaching is a difficulty. There are some similarities between the degree complement with "de" and the modality complement. For a long time, there has been a phenomenon of fuzzy classification in the academic circle, which also affects the teaching of Chinese as a foreign language. There are several different views on these two kinds of complements in the current textbooks. This makes students and teachers feel very confused. From the perspective of Chinese teaching, the author analyzes the characteristics, classification and grammatical significance of these two kinds of complements, and investigates the four sets of current teaching materials. It is found that: some teaching materials are confused in terms of terms and classification; some teaching materials are not fully reproduced in terms of knowledge points; the students are prone to have partial errors, and the situation of the clutch words with modal complements is ignored by most teaching materials. Some textbooks overemphasize Verb Copying in the arrangement of modal complements. Most textbooks are lack of context. The author puts forward some teaching suggestions. In class, teachers should concentrate on speaking and practicing, and focus on the types of errors that students are prone to make. The textbooks should be arranged according to the outline, the two kinds of "similar" complements should be clearly classified, the context should be added appropriately, and the textbooks compiled in South Korea can be nationalized. Students should listen carefully, participate in classroom activities and interact with teachers. Ask for advice in case of any problem you don't understand..

To produce well-qualified medical doctors, clinical training is a crucial part of medical education. To this end, teaching hospitals should be carefully selected and professionally managed. However, in Korea, there are no regulations or standards for training hospitals. Instead, some of the regulations that target teaching interns and residents are applied to teaching hospitals. In this study, we reviewed standards and regulations for training hospitals in other countries as a basis for proposing new standards for teaching hospitals in Korea. These new standards take into account the current environment of Korean medicine with the aim of designing appropriate educational programs for students and professional development systems for professors as well as providing educational resources and addressing the local community and international exchange opportunities.

This study set out to investigate the challenges to science teacher's teaching practices in the Anglophone sub-system of education in Cameroon secondary schools. A sample of 331 of these teachers was selected using the purposive sampling method. Data was collected by use of a questionnaire and was subjected to inferential analysis. The major findings from the multiple regression were challenges associated with the size and management of a science class have an effect on the teaching practices of a science teacher. However, challenges with availability of instructional resources did not have an effect on science teaching practices. Recommendations to solve the identified drawbacks include the provision of more classrooms to accommodate the ever growing population of students and the organization of many seminars through which teachers could be educated on how to handle classroom problems and improvise when necessary.

This study was conducted to find out the relationship between teaching presence and self-directed learning readiness in e-learning environment. 219 cyber university students finished the web-formatted questionnaires. The Self-Directed Learning Readiness Scale-Adult Based Education instrument and Teaching Presence Scale instrument were used. The results of the present study can be concluded as follow. First of all, teaching presence and self-directed learning readiness have a very high relationship in e-learning environment. Secondly, all five components of teaching presence have significant correlations with self-directed learning readiness. Thirdly, depending on the results of multiple regression analysis, only components of instructional contents and facilitating communication predict the self-directed learning readiness.

이 연구의 목적은 우리나라의 초등학교 수학과 문제해결 교육은 어떠했는지를 반추해보기 위해 그동안 우리나라 초등학교 문제해결 지도의 역사를 되돌아보고, 초등학교 수학과 교육과정과 교과서 분석을 통해 문제해결이 어떻게 다루어졌는지를 알아보기 위한 것이다. 그 결과 제4차 교육과정부터 2009개정 교육과정 현재까지 문제해결이 계속 강조되어 왔으나, 그에 따른 교과서에서는 교육과정을 제대로 반영하지 못한 경우가 많음을 알 수 있었다. 또한 제6차 교육과정에서 문제해결에 대한 교육이 양적으로 가장 많은 부분을 차지하다가 그 이후 조금씩 약화되고 있으며, 2007, 2009 개정 교육과정에서는 문제해결을 위한 교육으로 전환하려는 움직임이 있음을 알 수 있었다. 문제해결을 통한 지도는 제대로 이뤄지지 못하고 있다.
