Direct teaching is an essential function for collaborative robots for easy use by non-experts. For most robots, direct teaching is implemented only in joint space because the realization of Cartesian space direct teaching, in which the orientation of the end-effector is fixed while teaching, requires a measurement of the end-effector force. Thus, it is limited to the robots that are equipped with an expensive force/torque sensor. This study presents a Cartesian space direct teaching method for torque-controlled collaborative robots without either a force/torque sensor or joint torque sensors. The force exerted to the end-effector is obtained from the external torque which is estimated by the disturbance observer-based approach with the friction model. The friction model and the estimated end-effector force were experimentally verified using the robot equipped with joint torque sensors in order to compare the proposed sensorless approach with the method using torque sensors.

This paper recommends to teach technical writing as a part of the curriculum of engineering design courses. Some features of both engineering design and keystone design course as well as capstone design course for engineering students are studied before the relationship of those features with written communication are investigated. After the characteristics of collaborative writing are reviewed, some aspects of integration of teaching technical writing into engineering design courses are evaluated. Technical writing for engineering students is best taught by collaborative writing approach in engineering design courses.

본 연구의 목적은 도서관 활용수업에서 사서교사와 교과교사의 협동수업을 향상하기 위한 교수설계전략을 개발하는 것이다. 협동수업은 학교 공동체에서 사서교사의 교수자로서의 역할을 강화할 수 있는 중요한 경영 활동이다. 그러나 협동수업의 실천 전략인 도서관 활용수업은 협력수준에서 이루어지고 있으며 자료 선정을 제외하고는 교과교사가 교수-학습활동을 주도하고 있는 실정이다. 도서관 활용수업은 자원기반학습이기 때문에 정보활용교육의 방법적 지식과 교과의 학습주제가 통합되도록 설계되어야 한다. 그리고 수업 준비 과정에서 나타날 수 있는 시행착오를 줄이고 성공을 확산시킬 수 있어야 한다. 이러한 측면에서 도서관 활용수업용 협동수업 설계 전략을 '협동수업 상황기술-공동설계-공동수업-공동평가'와 같이 설정하였다

This study aimed to develop a new convergence course applying project-based learning (PBL) and collaborative teaching methods and identify its educational effects. The course development proceeded as follows: First, three instructors collaborated to define course goals, plan objectives, content, and methods, and create a syllabus for a PBL-based fashion studio course. Roles were divided to maximize expertise: one instructor focused on fashion design, another on three-dimensional cutting, and the third on flat cutting, and digital techniques. Second, the classes were conducted and feedback on student progress was shared, enhancing class quality and engagement. Third, teaching effectiveness was assessed through learner evaluation questionnaires, reflection journals, and performance assessments. Lastly, based on the results from these evaluations, positive aspects of the course were reviewed, and ways to modify it and enhance course quality for continuous improvement were explored. The results showed high satisfaction with the learning effects on major competencies, indicating that students not only effectively learned major skills but also improved their communication and teamwork. The students perceived the teaching methods positively allowing them to be more active in class. Instructors noted that the course produced higher-quality design and production outcomes compared to previous courses. Overall, the course applying PBL and collaborative teaching methods was found to improve educational quality and effectiveness, making it a valuable approach for learner-centered education.

The purpose of this study was to evaluate a group activity, reciprocal peer tutoring (RPT), in order to investigate advantages and challenges of RPT in promoting cooperative and collaborative learning environment for EFL University reading instruction. The participants in this study were 89 students taking an English reading course at a Korean university. RPT is a learning strategy whereby learners help each other and learn by teaching. This program was supported by a Vygotskyan perspective which assumes that learners gain mastery and develop cognitive skills through social interaction with more proficient others and their environment. This study relied particularly on participant perceptions through questionnaire survey and Anonymous Online class Report of the course. This study showed various advantages for tutors such as learning through teaching and becoming more autonomous and responsible for their own learning. Non-threatening and highly motivating learning atmosphere are parts of benefits for tutees. Other advantages for tutees included improved level of academic self-confidence, and motivation. This study also revealed several drawbacks associated with the problem of inaccuracy in students' production and students' demand for more direct teacher role. (182 words).

This study explored the contents of practical knowledge about educational planning in early childhood curriculum as constructed by kindergarten teachers at early career stages and then developed a collaborative model of educational planning. Subjects were 6 teachers at early career stages. Using the ethnographic method, data were collected by in-depth interviews. Research outcomes were : (1) teachers specifically worked on 'difficulties in adapting to the teaching job', 'age of children that the teacher cares for', 'integration of theory and practice', and 'variety of actual teaching situations.' (2) A model for collaborative educational planning was constructed on the basis of review of the literature on teachers' knowledge, educational planning for early childhood curriculum, and learning of community.

본 연구에서는 대학의 연구진들이 구성주의적 원리에 따라 설계한 교사-연구자간 협력적 연수 프로그램에 참여한 중등 과학 교사들이 구성주의적 수업을 내면화하는 과정을 탐색하였다. 연수 프로그램은 강의와 워크숍 및 소집단 활동 과정으로 구성되었다. 강의에서는 과학교육계의 동향 및 과학수업 프레임웍을 소개하고,워크숍에서 녹화된 실제 과학 수업 분석을 통하여 프레임웍에 대한 이해를 심화하였다. 소그룹 활동에서는 연구자와 참여 교사가 협력하여 프레임웍을 적용한 수업 모듈을 설계하였다. 지구과학을 전공한 4명의 중등 과학 교사가 자발적으로 워크숍에 참여하였다. 협력적 연수 프로그램은 전 과정을 녹화하였으며,반구조화된 면담을 연수 전과 후에 실시하였다. 녹음 및 녹화된 자료는 모두 전사하여 분석하였다. 참여 교사들은 프레임웍을 내면화하는 과정에서 주목하는 대상이 서로 달랐으며,다양하고 구별되는 교사의 경험과 교육 신념,교육 현실인식 등과 같은 다양한 요소들이 내면화 과정에서 갈등을 일으키거나 또는 그 과정을 촉진하였다. 수업 설계시 고려 요소를 결정하는 데에는 교사의 수업 경험과 학습자에 대한 인식이 중요한 영향을 미쳤다. 한편 참여 교사들은 주로 논의되었던 '탐구','적용', '모델' 등의 개념에 대해서 일상적인 의미로 받아들이거나,자신이 기존에 가지고 있던 개념으로 해석하는 경향을 보였다. 참여 교사들은 수업 시간에 비해서 기르칠 내용이 과다하다고 인식하고 있어서 수업 모듈을 설계하는 과정에서 내용은 강의식으로 전달하고,실험은 구성주의적 방식으로 설계하는 등 수업 구조를 이분화하려는 경향을 보였다. 본 연구 결과는 구성주의적 교사 연수와 교사 전문성 발달 과정에 의미있는 시사점을 제공할 것이다.

본 연구는 초등학교 6학년 수학수업에서 수업인터넷을 기반으로 한 협력학습의 다양한 수업사례를 제시하는데 그 목적이 있다. 이를 위해 수업인터넷 기반을 위한 수업환경의 설계 방법을 안내하고 다양한 수업방법에 대한 사례를 제시하였다. 본 연구는 D 광역시의 초등학교 6학년 한 개 반을 대상으로 2016년 3월부터 11월까지 약 9개월간 수업인터넷 기반으로 한 협력학습을 실시하여 대표적인 수업사례 유형을 정리하였다. 그 유형으로는 수업인터넷을 기반으로 한 교실 내 협력학습, 교실-교실 간 원격협력학습, 실시간 참여수업, 프로젝트 협력학습, 가상현실을 이용한 협력학습 등으로 구분할 수 있었으며, 다른 지역의 학생들과 동시간대에 협력학습을 실시할 수 있거나 Youtube를 이용한 학부모 및 교사 참관수업이 가능하다는 점이 기존의 협력학습과 차이가 있다는 것을 알 수 있었다. 이러한 수업사례는 교실 안에서 이루어지는 전통적인 수학수업을 벗어날 수 있는 사례로 제시할 수 있다는 점에서 미래교실에서의 스마트 기기와 인터넷을 활용한 수업방법에 대한 시사점을 제공할 수 있을 것이다.

Little has been known about the process of the language teacher professional development. The present study aims to investigate an assumption that anybody who has subject matter knowledge will be a good language teacher. A teacher with rich linguistic knowledge started to question the effectiveness of his online class. The teacher, in collaboration with a teacher trainer, became involved in the critical examination of his online class, seeking for more effective ways of teaching. The trainer provided the teacher with clinical supervision, which is characterized as developmental, collaborative, non-judgemental, interactive, and teacher-centered. The data collected at the multi-facets of the online teaching shows how the process of the teacher's decision-making became principled on the basis of recent developments in English language teaching, and how the teacher has gained pedagogical knowledge through reflection upon his teaching. The feedback from the students reveals that such teacher professional development is beneficial to student learning. These findings suggest that language teacher's professional development can take place when they are engaged in reflective teaching and classroom investigation. It is also suggested that the process of teacher development can be enhanced through collaborative supervision with trust, openness and congeniality between parties involved.
