The purpose of this study is to analyze the TPACK differences between pre-service and in-service teachers in China, and determine demographic influence variables on the differences between them. The participants of this study were 567 teachers, including 335 pre-service teachers and 232 in-service teachers from Ningxia, China. The results are as follows: First, The in-service teachers in the seven areas of TPACK scored higher than those of pre-service teachers; Second, The comparison of the average difference between teacher division and gender shows that the two factors have an interactive effect on TK. This study is meaningful because it compared the TPACK differences between pre-service and in-service teachers, and found out the effect of gender interaction on the differences in China; It provides practical suggestions for improving the TPACK ability of Chinese teachers. Finally, the discussion was conducted based on the results, and a follow-up study was suggested.

This study provides a concrete example of the development of the task in collaboration with the in-service teacher and the pre-service teacher. In the process, the roles of pre-service teachers and in-service teachers were analyzed and the possibility of cooperation was grasped. As a result, pre-service teachers and field teachers considered the level and interest of the students and considered mathematical contents in the process of developing the tasks. Each subject did not directly consider the interaction of the students and contents, but they could confirm the improvement of the tasks as their roles affected each other.

This study is to make an effective forecasting model for turn-out rates of the candidates with their visibilities, which are measured in their names on the media during the election period. I make a regressive model, with the data of 2010 gubernatorial election in Korea, where turn-out rate is dependent variable and each candidate's visibility, incumbency effect, local control party effect, corruption effect, strategy voting effect, restrain effect as a mid-term evaluation, and policy effect are independent variables. I got the model, T = -4.65 + 1.02V + 16.90 I + 16.78L - 9.12 R, where T is turn-out rate, V is candidate's visibility, I is incumbent effect, L is local control party effect, and R is restrain effect. This function can be used to predict turn-out rates of the candidates in the forthcoming gubernatorial election in Korea at a small outlay.

We investigated whether divergent thinking attitudes mediate the relationship between self-esteem and creative teaching beliefs among teachers. We examined differences in the mediating model we proposed in the groups of pre-service and in-service child care teachers. We found differences in the pre-service and in-service child care teachers in the proposed mediating model. Especially in the pre-service child care teachers, the mediating effect of divergent thinking attitudes was confirmed. There was a significant effect from self esteem to creative teaching beliefs and also a significant effect from divergent thinking attitudes to creative teaching beliefs. But in-service child care teachers, there was neither direct nor indirect effect of self-esteem to creative teaching beliefs. Suggestions for more studies and for better in-service education for the pre-service and in-service child care teachers are recommended for the future.

The purpose of this study was to analyze the problem solving strategies of ordinary students, gifted students, pre-service teachers, and in-service teachers with the 'chicken and pig problem,' which has multiple strategies to obtain the solution. For this study, 98 students in the 6th grade elementary schools, 96 gifted students in a gifted institution, 72 pre-service teachers, and 60 in-service teachers were selected. The researcher presented the "chicken and pig" problem and requested them the solution strategies as many as possible for 30 minutes in a free atmosphere. As a result of the study, the gifted students used relatively various and efficient strategies compared to the ordinary students, and there was a difference in the most used strategies among the groups. In addition, the percentage of respondents who suggested four or more strategies was 1% for the ordinary students, 54% for the gifted students, 42% for the pre-service teachers, and 43% for the in-service teachers. As suggestions, the researcher asserted that various kinds of high-quality mathematical problems and solving experiences should be provided to students and teachers and have students develop multi-strategy problems. As a follow-up study, the researcher suggested that multi-strategy mathematical problems should be applied to classroom teaching in a collaborative learning environment and reflected them in teacher training program.

Major countries in the world have established strategies for educating about artificial intelligence(AI) and with large investments are actively implementing these strategies. With this trend, domestic ministries have made efforts to establish national strategies to better educate students about AI. This paper presents the syllabus of AI classrooms which has been developed and presented to pre-service and in-service elementary school teachers for their use. In addition, the AI education tools they particularly preferred and their future plans for utilizing them in the elementary school classroom were investigated. Through this study, it was found that pre-service and in-service elementary school teachers strongly prefer lectures about AI education tools that can be immediately applied in the classroom, rather than learning about the theoretical basis of AI. At issue, however, is that the ability to utilize AI is usually based on a sufficient understanding of the theory. Thus, this paper suggests further study to identify better pedagogical practices to improve students' understanding the theoretical basis of AI.

This study reviewed the current status of in-service education programs for infant care teachers in early childhood education and care settings. In addition, the training program(titled "infant specialist program") which had been developed in one district of Seoul in order to assist the job performance and speciality for infant care teachers was discussed. The focus in the development of the training program, its teaching content and method were addressed in detail. The results related to evaluation of the training program of interest were reported. The infant care teachers who had participated in the training program reported that the levels of their teaching efficacy and those of knowledge of infant development from post-tests were significantly increased over time. In line with the main results of this study, implications for practice and policy were discussed.

For the wide spread of cyber education, it is important to understand the instructional characteristics of cyber education and its applications in the educational sites which help to cope with the practical needs and problems. This study was conducted to analyze the experience of cyber classes(working hours, tasks and evaluation, satisfaction level and instructional effectiveness, suggestions for cyber education) and use of instructional methodology (instructional activities, interaction frequencies, cooperative learning activities, instructional activities toward knowledge building). The data was collected from pre-service teachers(403) and in-service teachers(318) in June 2004. The results were that pre-service and in-service teachers all consider the satisfaction level and academic achievement level of cyber classes lower than that of FTF classes. Particularly the boring presentation of instructional materials and the inadequate instructional strategies for cyber classes were the biggest complains, and lack of interaction among peer groups and with instructors, lack of learning opportunity for cyber instructional strategies, limited group activities, lack of interaction with experts were followed. Limited types of evaluation also showed that cyber classes focus on results more than the process of students' academic achievement.

In this study, we developed the filed-experience learning support application. Because teachers want to use LBS in education area. In order to select fit functions, we carried out survey about functions that teachers want. Then, we analysed the result of survey and implemented the functions. Also, for survey about application's effectiveness, we selected elementary school teachers. Then we demonstrated and explained the application to them. The result of survey about application's effectiveness shows that application have higher utilization in education area.
