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.

This study aims to provide answers to two questions regarding the supervision of pre-service mathematics teachers: 'Who should carry out the work of supervision?' and 'How can it most skillfully be done?' The answer to the first question seems to be that, for a variety of reasons, university teachers and mentors appear best suited to do the supervision in a cooperative relationship with pre-service teachers. The assumption that seems to underlie the collaborative supervision is that field-based experiences are necessary and useful components of professional development in pre-service teacher preparation programs. With respect to the second question, it is suggested that a non-judgemental approach should be considered, along with strategies and techniques for judgemental supervision, as a way to make math teacher supervision more meaningful and helpful for the improvement of teaching and long-term professional development. It is hoped that a continued exploration of models of teacher supervision and evaluation of their effectiveness will help pre-service math teachers, supervisors and mentors learn more about teaching and improve their own teaching.

This study is to investigate the meaning of pre-service educare teachers' leadership experience about program development. The participants were 41 juniors in college, majoring in Child Welfare. They attended an 'infant & young childhood educare program development and evaluation' class for 15 weeks. During the given period they made documents from reflective journals and 5 participants among them were interviewed individually. Analyzing the documents sheds light on the meaning of the pre-service educare teahcers' experience. The results are as follows. First, pre-service educare teachers got a deeper understanding and attachment about communities. Second, they did a critical analysis about well-known home and abroad educare programs. Third, they had a opportunity of reflection about their education philosophy and competences. Forth, they experienced diverse leadership that is needed from educare teacher. The results showed the implications and suggestions about pre-service teacher education for educare teacher's curriculum leadership development.

This investigation studied 1)the correlations among pre-service child care teachers' behavioral characteristics, social support and self-efficacy, and 2)the mediating effects of pre-service child care teachers' behavioral characteristics and social support on self-efficacy. The subjects were 240 pre-service child care teachers working at S-center for nursery teacher education or I-center for nursery teacher education in the Incheon area. The findings are as follows. First, the relationships among pre-service child care teachers' behavioral characteristics, social support and self-efficacy were examined by showing correlations. Second, we found that in terms of the mediating role of social support in the relationship between pre-service child care teachers' behavioral characteristics and self-efficacy, type D and type S show self-efficacy; they also have a direct impact on the social support indirectly affected through. Thus, social support can be seen as having a partial mediating effect.

The purpose of this study was to get an implication on teacher education program, by exploring the difficulties pre-service elementary teachers have with their science lessons. 37 pre-service teachers were requested to write an anecdote about their science lessons during their 4 week practicum. By analyzing these anecdotes, the difficulties were grouped into several categories by the researcher, and then reconfirmed by the pre-service teachers themselves. The result showed that there were far more difficulties with practical work (cases: 48), than with content knowledge teaching (cases: 17). Among practical work related difficulties, the most frequent cases were: 1) when they have unexpected result different from scientific theory (cases: 10), 2) when they teach process skill and usage of lab equipments (cases: 8), and 3) when they do not have enough preparation for practical work (cases: 7). Unlike the result of preceding research on secondary pre-service teachers, there was no affective aspect problems. These difficulties also can be divided into 'problems' and 'dilemmas'. Whereas 'problems' can be settled by removing obstacles, 'dilemmas', a conflict-filled situation, require choices between competing values or aims. The use of scientific language, the decision on the level and amount of knowledge they teach, and disposal of unexpected experiment results caused such dilemmas in science lessons. The research results imply practical work should be more strengthened in the elementary teacher education program. And both teacher educators and pre-service teachers need to understand that practical teaching is a complex enterprise accompanying some 'dilemmas'. The role of science teachers as managers of dilemmas could be considered.

This study aims to investigate noticing of pre-service secondary mathematics teachers. For the purpose of this study, we analyzed journals of four pre-service mathematics teachers. Our analysis was based on a framework including three categories such as Aware, Interpret, and Response. As results, we found a tendency that pre-service secondary mathematics teachers have more general awareness of students and relatively fewer interpretations of students' mathematical thinking than other categories. In addition, in the category of Response, the pre-service secondary mathematics teachers were more likely to explain to students than to promote students' thinking through questions. Based on these results, we would like to discuss implications for pre-service secondary mathematics teacher education.

The purpose of this study is to investigate and analyze the understandings of elementary pre-service teachers about 'estimation' in the elementary mathematics. Together with this analysis, we identify elementary pre-service teacher's Mathematical Pedagogical Contents Knowledge(MPCK), especially focusing to Subject Matter Knowledge(SMK). In order to this goals, we investigate contents relating to 'estimation' from $1^{st}$ curriculum to 2009 revised curriculum and compare 'rounding up', 'rounding off', 'rounding' in the elementary mathematics textbooks. As results of investigations, 'estimation' has been teaching at the 'Measurement' domain from $3^{rd}$ curriculum, but contexts of measuring weaken from $7^{th}$ curriculum. 'Rounding up(off)' is defined three types in the textbooks from $1^{st}$ to 2009 revised curriculum. And we examine elementary pre-service teachers through the questions on these 'estimation' contents. On the analysis of pre-service teacher's understanding relating MPCK, four themes is summarized as followings; the understanding of '0' in the 'rounding up', the cognitive gap between 'rounding up' and 'rounding off', the difference of percentage of correct answers according to types of question in the 'rounding up', and the difference between the definition of 'rounding up' and the definition of 'rounding'.

The purpose of this study is to analyze the questions generated by elementary school pre-service teachers when reading the teacher's guide for the refraction of light, and to analyze the difficulties in understanding the concept and in making instructional plans. A total of 592 meaningful questions were generated by 283 elementary school pre-service teachers after reading the teacher's guide of 'light and lens' unit in the 6th grade of the 2015 revised curriculum. Of these, 306 questions are for understanding the concept of physics and 286 are pedagogical questions. As a result of the analysis, in terms of understanding the concept of physics, the elementary school pre-service teachers encounter difficulties in understanding the concept of the 'cause' of the phenomenon suggested in the textbook, such as the cause of refraction, the reason for scattering light, and the cause of the image change depending on the focal length of the convex lens. In terms of instructional planning, it was followed by questions about how to explain concepts, questions about not being able to explain concepts to elementary school students and having to teach only phenomena, specific explanation methods for specific concepts, and experimental methods. Although the teacher's guide contains various explanations and supplementary materials to help teachers understand the concept, it can be seen that there are many elementary pre-service teachers who cannot answer questions about some concepts even after reading the guide. For concepts with a high frequency of questions, it is necessary to prepare a tutorial that is more understandable. In the instructional plan, there were many questions about teaching methods and experimental methods, so it is necessary to provide more examples and specific experimental methods for explaining concepts in the teacher's guide.

The perception of pre-service teachers who participated as liaison teachers in the gifted education organization's different operating styles and the differences in the thoughts of these teachers were analyzed in this study. The inquiry survey was performed for 74 liaison teachers who had participated in the observational activities in the university annexed science gifted education center and the dormitory based gifted students education center supported by education of administration in Chungbuk Province. The individual in-depth interview was performed with 7 teachers based on the analyzed data. The perception of pre-service teachers who participated in as liaison teachers in the university annexed science gifted education center and the dormitory based gifted students education center was different from important element of the gifted and qualification of the teacher for gifted education. It was revealed that the differences between the education parts, education schedule and education methods of two the education centers, which were performed during the semester, influenced the perception of pre-service teachers who participated as the liaison teachers. The necessity of the systematic training on the observational skills and class contents were suggested as the essential support system for liaison teachers. The results of the study indicate that the gifted education organizations operating styles, the activities of liaison teachers, and pre-service teacher training program for gifted education emphasizes the long term actual guide experience at the education field for the gifted.
