This study investigated the prospective teacher's noticing of students' mathematical thinking from the perspective of how the prospective teacher pays attention to, interprets, and responds to the student's responses related to variables. The prospective teachers were asked to infer the students' thinking from the variables related to the tasks and suggest feedback accordingly. An analysis of the responses of 26 prospective teachers showed that it was not easy for prospective teachers to pay attention to the misconception of variables and that some of them did not make proper interpretations. Most prospective teachers who did not attend and interpret were found to have failed to provide an appropriate response due to a lack of overall understanding of variables. even though prospective teachers who did proper attend and interpret were found to have failed to respond appropriately due to a lack of empirical knowledge, even with proper attention and interpretation.

This study investigates the science teacher identity of pre-service science teachers (PSTs) in the context of a teaching practice course. Twenty-two PSTs who took the 'Biological Science Lab. for Inquiry Learning' course at the College of Education participated in this study. Artifacts created during the course were collected, and the teaching practices and reflections were recorded and transcribed. In addition, semi-structured interviews were conducted with nine PSTs, recorded, and transcribed. We found the science teacher identity was not well revealed at the beginning of the course. Authoritative discourse appeared in the early oral reflections of PSTs, indicating that the PSTs perceived oral reflection activities as 'evaluation activities for teaching practice'. This perception shows that pre-service teachers participate in teaching practice courses as students attending a university, performing tasks and receiving evaluations from instructors. After the middle of the course, discourses showing the science teacher identity of the PSTs were observed. In the oral reflection after the middle part, dialogic discourses often arose, showing that the PSTs perceive the oral reflection activities as a 'learning activity for professional development'. In addition, in the second half, discourse appeared to connect and interpret one's experience with the teacher's activity, indicating that the PSTs perceive themselves as teachers at this stage. In addition, the perception of experimental classes was expanded through the course. During the course, the practice of equalizing the authority of the participants, providing a role model for reflection, and experiencing various positions from multiple viewpoints in the class had a positive effect on the formation and continuation of the teacher identity. This study provides implications on the teacher education process for teacher identity formation in PSTs.

The purpose of this study is to analyze and present what aspects of the concept of function prospective mathematics secondary teachers emphasize when designing a class that introduces the concept of function using curriculum and textbooks. For this purpose, virtual instruction and reflections on virtual instruction were analyzed. The results are as follows. The prospective mathematics secondary teachers consider and introduce the concepts of function as correspondences and processes. Their conception of function was consistently observed during virtual instruction and reflections on virtual instruction. The prospective mathematics secondary teachers' conception of function was closely related to the form of expressing functions. These results provi e implications for prospective mathematics secondary teachers' education for introducing the concept of function based on the dependent relation between variables presented in the 2015 revision of the national mathematics curriculum.

In this study, we investigated preservice secondary science teachers' uses of curriculum materials in curriculum design through a case study. Two preservice science teachers at a college of education in Seoul participated in this study. We interviewed them about their beliefs on teaching and learning prior to their teaching students. We then observed their teaching and collected all of the teaching/learning materials. Semi-structured interviews were also conducted before and after the instructions. Their uses of curriculum materials were systematically analyzed in the aspects of reading, evaluating and adapting curriculum materials. The analyses of the results revealed that their uses of curriculum materials had a significant difference in curriculum design. There was a difference in the way of reading curriculum materials that derived from different perspectives of curriculum reconstruction. The perspectives of curriculum reconstruction also affected the way of adapting curriculum materials. While the 'adding' was an important adaptation in curriculum design with active perspectives, the 'changing' was an important one with passive perspectives. In addition, the degrees of evaluating curriculum materials from the learners' views depended on their beliefs on teaching and learning. It was also connected to qualitative differences of adaptation in 'increasing student control over an activity' and 'increasing teacher control over an activity'. Educational implications of these findings are discussed.

In this case study, we investigated the characteristics of pre-service secondary science teachers' curriculum design for teaching in science museums. Three pre-service secondary science teachers at a college of education in Seoul participated in this study. We have observed and recorded their teaching practices in science museums, collected all of their teaching materials, and conducted semi-structured interviews before and after teaching. All the data collected were analyzed by using the constant comparative method. The analyses of results revealed that the pre-service teachers structured their teaching in a series of pre-visit, during-visit, and post-visit as continuous activities. They attempted to reinforce students' learning experiences during the visit by providing post-visit activities, and also properly considered the principle that activity should be personally meaningful or relevant to students. However, they lacked the perceptions as well as the practical knowledge of reducing student's novelty of the science museum by providing activities prior to the visit, encouraging to engage in joint productive activities, promoting diverse social interactions, and providing students with choices and controls on their learning. On the bases of these results, we made some suggestions in pre-service teacher education for the professional development of teaching in science museum.

The image of scientists that learners have has an important impact on science learning and on science-related career choices. The image of the scientist was mainly analyzed using the drawing analysis method. Drawing analysis has limitations on drawing, mainly analyzing the external image of scientist. Science teachers' images of scientists and their perception of science-related careers are important factors in students' science learning and science-related career choices. However, research on science teachers is lacking. Therefore, the purpose of this study is to investigate the usefulness of measurement tools by developing and applying a scientist image measurement tool through the semantic analysis method, and to discuss the educational implications of the research by investigating the image of scientists and science-related professions of secondary pre-service science teachers. The subjects of the study were 79 male and 55 female for a total of 134 students in the 2nd and 3rd grades majoring in science education at a teachers college. The results of the research show that the image measurement tool consisted of four components: 'ability,' 'evaluation,' 'activity,' and 'emotion,' in 24 items. As a result of applying the developed measurement tool to the secondary pre-service science teachers, the image of the 'evaluation,' 'ability,' and 'activity' elements of the scientist were high, but 'emotion' was low. There was no statistically significant difference according to gender. It is found that science-related career perceive them as 'hard,' 'professional,' 'smart,' and 'complex.' In particular, male students perceive themselves as 'hard and difficult' while female students perceive it as 'challenging and complicated'. Finally, we discussed the usefulness of using the image measurement tool of the scientists, the image of the scientists of the secondary pre-service science teachers, and the educational implications on science-related career.

The aim of this study is to explore effective teaching strategies through an investigation of the problem-solving abilities and reasons for the unsuccessful problem solving of pre-service teachers. The participants of the study were 60 pre-service teachers who were expected to teach earth science in elementary school (40) and secondary school (20). The participants had taken a course in astronomy before they took part in the present study. The instruments for the study were a paper-and-pencil test and interviews. The results demonstrated that the pre-service teachers' abilities to solve problems were low. The pre-service teachers of the elementary school were inferior to those of the secondary school in their problem solving abilities. The causes for the unsuccessful problem solving were identified as follows: (1) lack of prerequisite knowledge to understand the motions of the moon and the planets, (2) failure to represent problems based on solution principles, (3) failure to apply the knowledge acquired in one setting to another, different setting, (4) frames of reference the frameworks for everyday life situation and for earth science problem situation, and (5) rote-memorization of facts rather than understanding the cause-and-effect relationships. The above causes for unsuccessful problem solving seemed to be related to the characteristics of novice problem solvers in general and of the tasks about the motions of the moon and the planets. Suggestions are made to enhance pre-service teachers' problem solving abilities based on the result of the study.

The purpose of this study is improving the teachers' self-efficacy for pre-secondary music teachers. The research questions for this study were the improvement for teachers' self-efficacy for pre-secondary music teachers and the pre-secondary music teachers' perception about peer mentoring. In this study performed the interview and analyzed the in self-reflection journal in order to identify the improvement effect of teachers' self-efficacy and the participants' perception change in the peer mentoring. As the results from analyzing the change in participant's perception about peer mentoring the mentors had the opportunity to review previous learning contents and practice experiences while developing their team activity and for the mentees. Mentees said that they were given various help from the mentors' advices and their interactions and communication with mentors. From these results, it could identify that there was positive change in participant's perception about the peer mentoring. Based on these results, this study analyzed that it would need to require some chances for pre-secondary music teachers to be given some educational practice and field experience utilizing various teaching methods in order to improve their self-efficacy and the perception of peer mentoring.
