The purposes of this study were to analyze the PCK of pre-service chemistry teachers and to know the changes of in PCK before and after the educational practice. For this study, four pre-service teachers majoring in chemistry education were selected as proteges and one professor of chemistry education department participated as a mentor. For the analysis of pre-service teachers' PCK, proteges' instructions, mentoring process, and semi-constructed interviews were collected. According to the results, most of the elements of the PCK were lack of proteges' instructions before the mentoring, because they didn't know the necessary practical knowledge for instructions. They also didn't know how they could apply their knowledge to the instructions. However, most of the pre-service teachers developed their PCK through the mentoring. This study shows that pre-service teacher's PCK could develop effectively by well-formed programs of mentoring before and after the educational practice in college education for pre-service teachers.

As the importance of technology increases, the need for TPACK, an knowledge for pre-service teachers, to integrate technology into education has increased. In order to improve TPACK of pre-service teachers, programming-based TPACK education program was developed. However, the developed educational program did not affect the self-efficacy of pre-service teachers. In order to solve this problem, in this study, the improved TPACK-P education program was applied to pre-service teachers to verify the change of self-efficacy. As a result, the improved TPACK-P education program was effective in the development of self-efficacy of pre-service teachers. In detail, pre-teacher's self-confidence and preference of task difficulty were significantly improved than previous. The TPACK-P education program, which is improved through this, confirms that the pre-service teacher promotes the integration of technology into the classroom rather than the existing education program.

In this study, we created, implemented, and evaluated the impact of proportional reasoning authentic investigative activities on the mathematical content and pedagogical knowledge and attitudes of pre-service elementary and middle school mathematics teachers. For this purpose, a special teaching model was developed, implemented, and tested as part of the pre-service mathematics teacher training programs conducted in Israeli teacher colleges. The model was developed following pilot studies investigating the change in mathematical and pedagogical knowledge of pre- and in-service mathematics teachers, due to experience in authentic proportional reasoning activities. The conclusion of the study is that application of the model, through which the pre-service teachers gain experience and are exposed to authentic proportional reasoning activities with incorporation of theory (reading and analyzing relevant research reports) and practice, leads to a significant positive change in the pre-service teachers' mathematical content and pedagogical knowledge. In addition, improvement occurred in their attitudes and beliefs towards learning and teaching mathematics in general, and ratio and proportion in particular.

The sense of happiness of early childhood teachers has a great influence not only on teaching but also on infants. The purpose of this research is to investigate how prospective pre-service teachers' sense of happiness influence their teacher professionalism and teacher efficacy. The subjects were 264 pre-service teachers' in Gwangju metropolitan city and Jeollanamdo province. Statistical analysis of this study was done by Pearson's correlation coefficient and multiple regression analysis using SPSS WIN 22.0 program. The results of this study were as follows. First, there were significant positive relationships among the sense of happiness on teacher professionalism and teacher efficacy. There was a significant positive correlation between external happiness, inner happiness, and self-regulated happiness, which are indicating that there is a meaningful correlation between pre-service teachers' sense of happiness, teacher professionalism and teacher efficacy. Second, the sense of happiness was an important factor for predicting the teacher professionalism and teacher efficacy of pre-service early childhood teachers. The results of this study show that the pre - service teacher 's sense of happiness is a predictor variable that positively affects teacher professionalism and teacher efficacy. In conclusion, It is meaningful in seeking ways to improve teacher education by enhancing the euphoria of prospective pre-service teachers during school life and strengthening positive aspects of the educational contents and processes of the institutions that train infant teachers.

The purpose of this study was to investigate the astronomy-related concepts formed by elementary school pre-service teachers and analyze the distribution of misconceptions. The study was conducted on 43 pre-service teachers enrolled in the second year of an elementary teacher training college located in the central region of Korea. As a result of the study, first, pre-service elementary school teachers' misconceptions about astronomy concepts showed a diverse distribution. In particular, pre-service elementary school teachers still had misconceptions regarding seasonal changes, which were pointed out in many previous studies. Second, pre-service elementary school teachers had formed concepts at the level of simple memorization of astronomy concepts and were having difficulty applying the concepts they knew to various cases. Based on these research results, future astronomy-related education should be directed toward understanding astronomical phenomena through the application and application of various cases rather than simple memorization, and astronomy education in teacher training courses and teacher training should also reflect this content.

The study aims to find out and examine the variables that make a difference between pre-service teachers' child care efficacy (CCE) and general self-efficacy (GSE). The subjects were 232 pre-service child care teachers going to an educational institution and a college. The results are as follows. First, the variables of "age", "teacher training facilities", "field experience in child care centers", and "experience of child care" and "paraprofessional teachers" are important variables in pre-service teachers' CCE. Second, the variables of "age", "level of education", "teacher training facilities", "field experience in child care center", and "experience of child care or paraprofessional teachers" significantly affect the pre-service teachers' GSE. Third, the "age" variable is essential in explaining pre-service teachers' GSE. The Pre-service teachers' GSE is significantly related to the pre-service teachers' CCE.

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.

In this study, the educational effect was investigated by providing a teaching program so that pre-service chemistry teachers could apply model ignorance education to teacher training practice. The teaching program was constructed in consideration of the sensemaking concept proposed in the study of Odden & Russ and the process of teacher sensemaking proposed by Asli et al. The subjects of this study were 23 pre-service teachers in the 4th year of chemistry education department at a teacher training university in the central region of Korea. In order to form a sensemaking for the model's ignorance education, the teaching program consisted of four stages; the initial idea generation stage, cognition of model's ignorance stage in a inconsistent situation, the lesson strategy construction stage for model ignorance education, and lesson plan & practice stage during teacher training practice. In the first stage of this program, pre-service teachers' initial ideas about the Arrhenius model and Bronsted-Lowry model of acid-base reaction, and the electron transfer model of the oxidation-reduction reaction were investigated. In the second stage, inconsistant situation that cannot be explained by the knowledge of model was presented to recognize the ignorance of the model. The third stage was to develop the teaching ability of model's ignorance through textbook analysis and lesson strategy composition activities. As a final stage, during the teacher training practice, the pre-service teachers were asked to plan and practice the implementation of the model's ignorance education. Through the teaching program to form a sensemaking for ignorance education of the models, pre-service teachers had come to recognize the ignorance of the model, acquired ability to organize and execute lesson strategies reflecting model ignorance, and acquired recognition of the educational value and necessity of teaching the ignorance of models.
