The study is to research their parenting efficacy and parenting practices of a parent teacher as a volunteer(PTV) in the kindergarten. The subjects were mothers (N=127) in Choongbuk Province who had had volunteer education as a teacher assistant. The data were collected by their completing a questionnaire about Parenting efficacy and a Parent As A Teacher inventory (PAAT). The results include as follows: firstly, in PTV's parenting efficacy, 'the type of educational institution children are attending' is an important variable. Secondly, 'mother's educational background', 'father's educational background', and 'the type of educational institution children attending' are important variables in volunteer parents' parenting practices. Besides, 'mother's educational background' and 'participation motivation in volunteer activity' are important variables in parenting practices of 'control/permission' and of 'teaching/learning', and in general parenting practices. Finally, 'parenting efficacy', 'mother's educational background', and 'the sex of children' are important variables in volunteer teachers' parenting practices.

This study examines whether the reinforcement theory would be effectively applied to teaching assistant robots between a robot and a student in the same way as it is applied to teaching methods between a teacher and a student. Participants interact with a teaching assistant robot in a 3 (types of robots: positive reinforcement vs. negative reinforcement vs. both reinforcements) by 2 (types of participants: honor students vs. backward students), within-subject experiment. Three different types of robots, such as 'Ching-chan-ee' which gives 'positive reinforcement', 'Um-bul-ee' which gives 'negative reinforcement', and 'Sang-bul-ee' which gives both 'positive and negative reinforcement' are designed based on the reinforcement theory and the token reinforcement system. Participants' task performance and reaction rate are measured according to the types of robots and the types of participants. In task performance, the negative reinforcement robot is more effective than the other two types, but regarding the number of stimulus, the less the stimulus is, the more effective the task performance is. Also, participants showed the highest reaction rate on the negative reinforcement robot which implies that the negative reinforcement robot is most effective to motivate students. The findings demonstrate that the participants perceive the teaching assistant robot not as a toy but as a teaching assistant and the reinforcement interaction is important and effective for teaching assistant robots to motivate students. The results of this study can be implicated as an effective guideline to interaction design of teaching assistant robots.

Science festivals have occupied a very important axle in informal science education that enables students to experience the amazement of scientific experiments to think over scientific principals beyond the formal education in the classrooms. Among the concerned person, the most benefit-taken group may be the assistant who help the participants experience the activities in the festival. In order to find out the ways to make the student assistant's participation into a meaningful education experience, we analyzed the types of the activities in the science festival as well as the characteristics of the interaction between the student-assistants and the participating students are studied. The research findings are as follows: First, most activities in the science festival had related to the scientific concepts or principals; however, the understanding of the concepts and principals didn't highly affect the procedure of the activities. In many cases the students operated and made results without checking the related concepts or principals. Second, the student-assistants showed the consistency of operation in guiding their activities. They were explaining mainly the process of the experiments without giving a chance to think of related concepts or principles. We suggest that teacher should consider the student-assistants' learning in the festival as well as that of the participants.

What is the life of an assistant professor working at a college of education look like? The purpose of this paper is to describe and understand the life of an assistant professor as a science education researcher and as a teacher educator from exploring his life in a local national university. The researcher (I) conducted an autobiographic research in which I reconstructed and reflected my life by myself. I collected data/records on the life of myself, and developed a framework to classify them. The life of an assistant professor was categorized into the official life at the university and the personal life, and the former was sorted into education, research, and service and the latter was divided into personal and family. From the various profiles of my life, I found the main theme of 'change' and 'learning,' from which I reconstructed my life in narratives. I can express myself as an assistant professor with 'from myself to others,' 'balancing society and isolation,' and 'increasing room to maneuver through continuous learning.' I reflected my life and the role of a professor at a college of education, and discussed the educational implication of the result.

Objective: The purpose of this study was to investigate the condition of career happiness according to personal and organizational variables of childcare teachers. Methods: For this purpose, a total of 1,035 teachers were surveyed. The validity of the career happiness survey tool was examined through previous research, expert review, and factor analysis. Results: The results of the study are as follows. The individual variables influencing career happiness of childcare teachers were mainly age, and there was a difference in the career happiness of teachers over 40 years old and teachers under 29 years old. Second, the teachers at home daycare centers showed a high level of interpersonal relationships and working hours. The teachers at workplace daycare centers have a good balance between work and life, and teachers at corporate group daycare centers have a high sense of happiness about income. The childcare teacher's career happiness was generally higher than infant teachers, and the support of the assistant teacher had an effect on the career Happiness of the teachers. Conclusion/Implications: The results suggest that separate teacher support is needed to increase the career happiness of teachers according to their age and institutional variables.

The purpose of this study was to analyze Early Childhood Teachers' awareness of R-Learning. The Subjects were 6 Early Childhood Teachers who experienced to use Robot in their teaching and learning. The data was analyzed through semi-structured in-depth interview and teachers' journals. The results showed possibilities and limitations of R-learning. As possibilities of R-learning, it was found that robot is am attractive teaching materials. In addition, it was found that robot might be an assistant teacher. Third, robot helps children improving their social development. Fourth, teachers might get confident while using robots in their teaching and learning. However, there were limitations of R-learning. First, teachers need to understand what R-learning means. Second, there are some functional problems of R-learning. Third, there are lack of qualitative contents of R-learning. Finally, robots need to be general to every children.

The purpose of this study was to investigate the nature of pre-service elementary teachers' metaphors on mathematics textbooks. Their metaphors describe individual and collective patterns of thinking and action on mathematics teaching and learning. To analyze their metaphors, qualitative analysis method based on Lakoff and Johnson's theory of metaphor (1980) was adopted. Metaphors on mathematics textbooks were elicited from 161 pre-service elementary school teachers through writing prompts. The writing prompt responses revealed three types and thirteen categories: As Type I, there were (1) 'Principles', (2) 'Summary', (3) 'Manual', (4) 'Encyclopedia', (5) 'Code', (6) 'Guidelines', and (7) 'Example'. As TypeII, there were (9) 'Assistant', (10) 'Friend', (11) 'Scale', and (12) 'Ongoing'. As TypeIII, there was (13) 'Trap'. Among these categories, 'Guidelines', 'Assistant', and 'Ongoing' were the most frequently revealed. These results indicate that the relations of mathematics curriculum, textbooks, and classrooms are not a unilateral way but should communicate with each other.

The purpose of this research is to design and develop teacher assistant contents 'My Class' for an intelligent robot iRobiQ, using in early childhood educational setting. After observing daily activities and correspondence role of teachers in educational settings, we selected the robots' target contents as 6 main functions (Attendance, Activity, Gallery, Learning, Role Calling, and Timer). We designed the contents according to the PLU (Player-Learner-User) model which suggests importance of entertainment, education, and enabling features to meet player, learner, and user requirements. We also considered 'emotional' features to satisfy 'companion' requirements. The developed contents in this study was deployed in kindergarten classrooms consisting of five-years-old for 4 weeks to see how they response and use the contents. We found that both teachers and children were likely to show positive responses to the contents. Especially, young children responded to the entertainment and emotional features more actively than to the other features. And they continually explored for something new inside the contents. Finally, this paper discusses what should be considered to develop more useful teacher assistant contents for iRobiQ.
