The aim of this study is to look into the meaning and sub-factors of spatial orientation, compare and analyze mathematics curriculums and textbooks of several countries with respect to spatial orientation and offer suggestions to improve teaching spatial orientation in elementary school mathematics in Korea. In order to attain these purposes, this study examined the meaning and sub-factors of spatial orientation through the theoretical consideration regarding various studies on spatial sense. Based on such examination, this study compared and analyzed mathematics curriculums and textbooks used in South Korea, Singapore, Japan, China, Hong Kong, Finland, United States of America, and Germany with respect to contents of mathematics curriculum and textbooks in grades, sub-factors of spatial orientation, and contexts for spatial orientation. In the light of such theoretical consideration and analytical results, this study provided suggestions for improving teaching spatial orientation in elementary schools in Korea as follows: extending content of spatial orientation in mathematics curriculum, emphasizing spatial orientation across the several grades, especially in the upper grades, providing opportunities to learn the sub-factors of location, direction, coordinates, route, and distance variously, and utilizing various familiar and realistic contexts in the world around students.

The purpose of this study is to identify the teaching professionalism of the two teachers for secondary science-gifted students in perspective of teaching orientations. Both teachers have been taught biology to secondary science-gifted students for more than six years and they have received in-service training in gifted education. Teachers' orientations were investigated through in-depth interviews and observing lessons. For the data collection, videotapes were recorded during two lessons and two in-depth interviews for each participant were conducted. All recorded data were carefully transcribed and analyzed. Some unique characteristics of teaching were identified from the class instruction of each participant. Both teachers revealed 'Open Inquiry' orientation. This was reflected by their educational goals and beliefs that they should help science-gifted students to grow themselves as scientists by enhancing their inquisitiveness and creative problem solving ability. However, each teacher had shown different teaching orientations such as 'Academic Rigor' and 'Discovery' that seemed to have influence on the level or the range of subject matter covered in the classes. Teachers' science teaching orientations have been changed by their subject of teaching and their experiences in teaching the gifted. In the process, teachers' educational philosophy about gifted education plays an important role in teaching orientation. Based on the ongoing teachers' efforts for enhancing his/her professionalism, the teachers seemed to critically review theoretical knowledge of the science teachers in gifted education through self-reflection on their own teaching methods. When teacher's educational philosophy about gifted education was established and internalized, science teaching orientations in teaching practice seemed to be consistent with his/her goal of teaching.

This dissertation aims to analyze various safety accidents taking place during physical education class according to physical education teacher's value orientation, to identify teacher's value orientation that can minimize safety accidents, and to provide basic materials for safe and smooth class management. For this purpose, data have been collected from 261 physical education teachers at some middle and high schools in G City in Kyung-Ki Province and Busan Metropolitan City. The materials were treated as follows: The variables on demographic characteristics of physical education teachers are determined by t-test ; The analysis of one-way ANOVA and relationship between value orientation and safety accident prevention activities was conducted through Pearson's linear correlation analysis and multiple regression; The analysis of the relationship between value orientation and actual conditions of safety accidents was conducted through logistic regression. First, there is almost no awareness difference of physical education teachers' value orientation according to demographical variables. The value orientation physical education teachers consider to be the most important is, however, mainly 'mastery of disciplinary lesson.' There is a statistically significant difference in safety accident prevention activities according to demographical variables. Teachers' focuses in class contents showed a significant difference according to teaching experience and working area, while the dependency on facility has a significant difference according to teaching experience and school type. Second, there is no correlation between physical education teacher's value orientation and safety accident prevention activities because there is virtually no statistically significant difference between them. It means that safety accident prevention activities are not related with on which teachers place emphasis among mastery of disciplinary lesson, social reconstruction, self-realization, ecological integration and value orientation on learning process. Third, the analysis of safety accident prevention activities according to physical education teachers' value orientation revealed that the lower value orientation in social reconstruction is, the more safety accidents teachers experience. It is also found that crashes among students, ball games and leg injuries are inter-related with social reconstruction in value orientation, over-motivation and unskilled motor function ; athletic sports with value orientation on learning process and safety prevention training ; unskilled motor functions with value orientation in ecological integration and disobedience to teacher's directions ; winter accidents with mastery of disciplinary lesson in value orientation. In conclusion, the research indicates that physical education teacher's value orientation according to demographical variables didn't show any significant difference, while one according to safety accident prevention activities showed significant difference. Besides, physical education teachers' value orientation is not related to safety accident prevention activities, but the relationship between value orientation and actual conditions of safety accidents showed correlations according to each variable. Especially, teachers with lower value orientation in social reconstruction experienced more safety accidents. Therefore, physical education teachers can manage physical education class more safely with more emphasis on value orientation in social reconstruction.

The purpose in this study is to identify beliefs about curriculum orientation of Korean secondary school home economics teachers for the development of home economics curriculum and the change of their curriculum orientation. The curriculum orientations explored were academic rationalism, technical, cognitive process, personal relevance, and social reconstruction. A mail questionnaire, Individual Curriculum Orientation Profile (ICOP), was used to survey randomly selected 525 home economics teachers. Home economics teachers agreed with the cognitive process as their predominant curriculum orientation. The second predominant type with which home economics teachers agreed most was personal relevance orientation. Home economics teachers’age, major, college type, and teaching years were significantly related to the academic rationalism curriculum orientation, and the college type for bachelor’s degree was significantly related to the technical curriculum orientation. Age and major in master’s degree were significantly related to the social reconstruction curriculum orientation.

This study aims at exploring the features of science teaching orientation (STO) and its relationships with other PCK (pedagogical content knowledge) components. To do this, based on the definition of STO by Friedrichsen, Driel, & Abell(2011) and PCK model by Magnusson, Krajcik, & Borko(1999), we observed one experienced elementary teacher's science lessons for 21 lesson hours (10 hours of 'Motion of Objects' and 11 hours of 'Light and Lens') and carried out qualitative analyses of the data obtained from lessons observation, teacher interviews, and CoRe (content representation) responses. We analyzed the teacher's three aspects of STO (i.e. beliefs about the goals and purpose of science teaching, beliefs about the nature of science, and beliefs about science teaching and learning) which can converge into an overall STO of 'inquiry'. And these aspects of STO appear to interact differently with four PCK components (i.e. curriculum knowledge, learner knowledge, instructional knowledge, and assessment knowledge) depending on the topic of the lesson. It is hoped that this in-depth understanding of the features of STO and its relationship with other PCK components would provide useful information on how to monitor and improve STO and PCK of elementary teachers.

The purpose of this study is to investigate beginning secondary science teachers' teaching practices in terms of motivating and understanding students. Six first-year teachers participated in this study. Data were collected by classroom observations and structured interviews. Instructional materials used during the class were also collected to understand teaching practice. Lessons observed were video-tape recorded and the teachers were interviewed. Video- and audio-tape recording were transcribed. The framework, developed by Knowles Project Team of Michigan State University, was adopted and revised according to Korean classroom context and employed as an analytical tool for teaching practices. The beginning secondary science teachers intention ranged from 'Managing Work' to 'School Science.' No teachers revealed 'Reform Science Teaching' orientation. For the execution of science lessons, one teacher with 'Managing Work' orientation showed 'expert' level of execution, but the others executed at a 'novice' level. Beginning science teachers need to be guided and informed about 'Reform Science Teaching' for motivating and understanding students to develop professionally.

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.

The purpose in this study is to determine the relationship between the curriculum orientations and professional teaching practices of Korean secondary school home economics teachers for the development of home economics curriculum. The instruments, Individual Curriculum Orientation profile(ICOP) and Professional Teaching Practice(PTP) were used to survey randomly selected 525 home economics leachers. The curriculum orientations explored were academic rationalism, technical, cognitive process, personal relevance, and social reconstruction. The professional teaching practices examined were customary-instrumental, interactive and reflective practices. Using canonical correlation, home economics teacher's teaching practices were found to be significantly related to their curriculum orientations. However, only 17.7% of the variability in professional teaching practices was explained by the five curriculum orientations.
