마이크로티칭은 교사들의 모의수업을 녹화한 후 피드백 평가 성찰의 과정을 통하여 수업 스킬을 개선하도록 돕는 교수-학습방법이다. 마이크로티칭과 관련된 선행 연구를 분석한 결과, 마이크로티칭을 진행하면서 발생하는 시간적 물리적 부담을 줄이고, 더욱 의미 있는 성찰의 기회를 제공할 필요가 있음을 알 수 있었다. 이를 위하여 본 연구에서는 웹 기반 마이크로티칭 지원 시스템을 개발하였다. 개발된 시스템을 통해 마이크로티칭 동영상을 공유하고, 전체 절차와 단계별 활동을 구조화할 수 있으며, 수업 계획서 업로드 체크리스트 등을 통해 마이크로티칭 활동이 보다 체계적이고 심도 있게 이루어지도록 하였다. 또한 다양한 유형의 피드백을 원하는 시점에 정확하게 입력할 수 있는 기능을 지원하였다. 이 시스템은 교사들의 수업스킬 증진뿐만 아니라 프레젠테이션, 면접 스킬을 향상시키는 데 활용될 수 있을 것으로 기대한다.

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 improve robot motion control in teaching and operating the expert system/world coordinate system (TOES/WCS) constructed in the previous study. The major contribution of this study is reduction of the inaccuracy in coordinated reading and the movement time of robots in macro motion control. This study also reduces undesirable time of micro motion control by using an unit control (UC) and a micro unit control (MUC) in micro motion control.

21세기 지식기반사회로의 변화는 대학의 역할과 성격에도 혁신을 요구하고 있다. 최근 대학들은 산업화 사회에서 산학연을 중요시하여 전문 기술자의 양성이라는 교육 목적을 갖고, 고등교육 수준의 질적 수월성과 직업교육에 대한 교육 책무성을 확보해야 한다는 인식을 하고 있다. 그러나 대학교수들이 실제적으로 수업 전문성을 제고할 수 있는 기회가 충분하지 않다. 따라서 교수들이 풍부한 현장성을 갖고 있어도 수업에서 실제적인 수업내용에 접근하여 이를 제대로 발휘하지 못하는 경우가 있다. 이는 교수직에 진입한 이후의 수업 전문성에 개발 기회가 충분히 주어지지 못했기 때문이다. 그러므로 대학은 교수들에게 수업 전문성을 능력을 향상시킬 수 있는 기회를 제공해야 한다. 본 논문에서는 이러한 방안의 일환으로 수업개선 멘토링 프로그램과 아울러 수업개선을 위한 포토폴리오와 마이크로 티칭 방법론을 제안한다.

This article discusses the teaching of listening and reading skills through enhancing the awareness of pronunciation. First, it examines the problems which take place in listening comprehension, and seeks the ways in which we can teach the skill rather than simply practise it. The approaches proposed are based on micro-listening exercises which practise individual subskills of listening, especially by using the cloze test and tracking. The issue of using authentic materials is then examined for teaching recognition of the features of natural speech. Finally, it is argued that classroom activities need to take account of the true nature of real-life L2 listening.

This study gives opportunity for investigating how student teachers view the teaching profession and how they transfer their pedagogical knowledge into practice. The aim of the study is to investigate the teaching skills student teachers gained in the assessment of micro teaching of their peers. The participants are 30 mathematics student teachers enrolled in the teacher training program in a state university. Document analysis and semi-structured interviews are the research instruments and inferential & descriptive statistics are used for the data analysis. The findings suggest that the qualitative and quantitative peer assessments of student teachers were graded differently which results from the difference of perceptions about teaching and different conceptualizations of the teaching qualifications.

For the current study, five Asian English teachers participated in their case studies to investigate an in-depth understanding of their beliefs about teaching and learning English as a foreign language. Data were collected through structured and unstructured interviews, written documents, observations of teacher-participants' micro teaching, a research methodology journal and a self-reflection journal. This study described the beliefs that Asian English teachers brought to the teacher preparation program and examined to see if these teacher-participants who were involved in case studies perceived change in their beliefs. The study found that formal and informal learning experiences greatly shaped the way teacher-participants' beliefs about the way learning and teaching ought to be. In addition, early experiences of learning and teaching influenced teacher-participants' change in beliefs.

This paper presents the design, fabrication, and calibration of a piezoelectric polymer-based sensorized microgripper. Electro discharge machining technology is employed to fabricate super-elastic alloy based micro gripper. It is tested to present improvement of mechanical performance. For integration of force sensor on the micro gripper, the sensor design based on the piezoelectric polymer PVDF film and fabrication process are presented. The calibration and performance test of force sensor integrated micro gripper are experimentally carried out. The force sensor integrated micro gripper is applied to perform fme alignment tasks of micro opto-electrical components. It successfully supplies force feedback to the operator through the haptic device and plays a main role in preventing damage of assembly parts by adjusting the teaching command.

Online and offline mixed teaching mode has become an important way to promote the connotative development of higher education. Under the background that offline teaching has become mature, in order to further promote the development of online education, and promote the implementation of the mixed teaching mode, to mix and to provide basis for the construction of the mixed teaching mode, this study takes the online learning effect as the evaluation basis, adopts the online questionnaire survey to conduct statistical analysis of the online learning behavior of 2213 college students, and discusses the differentiation phenomenon of online learning groups from the micro, meso and macro perspectives. It is found that there are significant differences in the online learning effect of college students in terms of the type of learning platform, whether the school implements the online offline mixed teaching mode, education background, grade (bachelor's degree), and region. Colleges and universities should strengthen the promotion of online and offline mixed teaching mode; The online learning platform should improve the platform function and strengthen the functional differentiation design of learning resources for students. Education departments pay attention to the learning effect of online learners in different regions, and bridge the gap in regional education.
