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.

Problem-based learning (PBL) is an effective teaching-learning strategy for enhancing students' motivation, problem solving ability, and creativity. Its educational values coincide with the aim of open-inquiry activity introduced in 2007 revised national curriculum. From this aspect we designed the PBL open-inquiry program and implemented to 202 first year middle school students in Gyeonggi provincial office of education for one semester. We developed an energy related PBL problem. The program was designed in four steps: 'understand the problem,' 'investigate information,' 'solve the problem,' and 'present and evaluate the result.' Through the program, students did such activities as 'make Know/need to know chart,' 'group discussion,' 'search information,' and 'preparation of group report.' After completing the program, a survey was conducted to understand the students' perception of the program. The results are as follows: First, 40.6% of students showed positive attitude toward the program. Especially, students responded that 'make Know/need to know chart' was very useful. However, some students responded that 'search information' and 'preparation of group report' were difficult to perform. Second, male students showed positive attitude toward the PBL program compared to female students. Also students had higher scores in attitude toward science, showed more positive attitude toward the PBL program. Third, there was a significant correlation between attitude toward science and perception of PBL steps. Based on survey results, some suggestions were made for teachers who were planning to implement PBL in open-inquiry program.

This study aims to analyze how pre-service science teachers' reflective thinking is presented during the microteaching process. The subjects of this study were 13 students who attended a lecture course on science teaching methods offered by the Department of Science Education of the College of Education at a national university. The simulated lessons that were performed during the microteaching process went through peer assessment and self-assessment. Then, the next set of lessons was conducted based on the assessment results. After the first set of simulated lessons, the pre-service teachers' reflection at the routine and technical levels was most remarkable in the focus dimension. In the inquiry and change dimensions, technical reflection stood out. Dialogic or transformative reflection was rarely presented. In addition, most of the pre-service teachers displayed mingling patterns of reflection levels in all of the three dimensions. The results of this study, in particular, prove that microteaching has a high level of applicability in terms of reflective thinking and instructional technology. Accordingly, there is a need for subsequent studies to create a new model that can encourage pre-service teachers' reflective thinking by structuralizing peer and self-assessment during the process of microteaching.

The purpose of this study is to examine the anxiety arising from the budgetary and mental problems of graduate school students. Three graduate students majoring in Earth science examined conflict situations by using a narrative inquiry technique. First, participants become psychologically unstable due to a lack of knowledge in the field of Earth science, lack of mentors, lack of information related to academic schedules, late start compared to others, financial difficulties, and discrimination in the scholarship system. Second, participants felt hope from the perception that their lives are valuable, that they can change students for the better, and that they are developing themselves. Third, with their hope, the study participants bore the previously mentioned inferior situation mentioned above. They are, however, torn between becoming secondary school teachers and attempting to reroute their career path due to certain circumstances. Based on the results of the examination, the following conclusions were drawn. First, there should be improvements from graduate school management based on collecting and scrutinizing the demands of students in the to fulfill their needs. Second, providing psychological counseling for students who have problems overcoming their anxieties. This study expects graduate schools to not only emphasize training of incumbent teachers, but also suggest ways that can satisfy students to make better learning environment for all its members.

We studied the effects of science high school students on the change of epistemological beliefs in chemistry and the academic achievement of chemistry by completing 'advanced chemistry'. For seven months from July 2023 to January 2024, 80 first-year students at G Science High School in Gyeongnam were surveyed and analyzed for epistemological beliefs about chemistry before and after classes in advanced chemistry. Chemistry academic achievement was classified by 'upper' and 'lower' levels based on the end-of-semester grades of 'advanced chemistry' in the second semester of the first year and analyzed with the SPSS 28 program. After completing advanced chemistry, the epistemological belief in chemistry increased in the proportion of favorable responses. After completing advanced chemistry, the proportion of favorable responses increased in detailed factors such as 'effort', 'math link', 'outcome', 'reality link', and 'concepts', while the 'visualization' factor decreased. Although completing 'advanced chemistry' positively changed students' epistemological beliefs about chemistry, visual expression showed little contribution to understanding chemical concepts. Based on the above results, we will have to focus on the design of instructors' teaching-learning, such as learner-centered inquiry experiments, creative visual expressions, etc., for successful chemistry teaching-learning.

In this study, we comprehensively investigated the cases of science teachers who implemented NOS assessments in Science Inquiry Experiment. Two science teachers working at high schools located in Seoul who taught and assessed NOS in Science Inquiry Experiment according to the 2015 revised curriculum participated in the study. We collected lesson and assessment materials and observed NOS lessons and assessments. We also conducted interviews. Based on the collected data, we analyzed the processes of the teachers' NOS assessments. The analyses of the results revealed that the teachers constructed the assessments by themselves due to a lack of NOS assessment experience and related materials. They had difficulties in selecting an appropriate assessment method and constructing assessment questions and criteria. Both teachers found it difficult to assess an understanding of NOS because it concerns the subjective views of individual students. Therefore, they had difficulties in setting detailed assessment criteria, which also led to difficulties in the overall assessment process. There was a difference in the reflective level of the assessments between the two teachers. In the reflective activities of low levels, the assessments were not properly enacted because it was difficult to infer students' understanding. Orientation toward teaching NOS influenced the perceptions of NOS assessment and overall lessons, resulting in a difference in NOS assessments. Finally, the absolute evaluation of Science Inquiry Experiment also affected teachers' NOS assessments. Based on the above results, implications for effective NOS assessments in schools are discussed.

The purpose of this study is to identify the teaching professionalism of the two teachers for secondary science-gifted students in perspective of teaching orientations. Both teachers have been taught biology to secondary science-gifted students for more than six years and they have received in-service training in gifted education. Teachers' orientations were investigated through in-depth interviews and observing lessons. For the data collection, videotapes were recorded during two lessons and two in-depth interviews for each participant were conducted. All recorded data were carefully transcribed and analyzed. Some unique characteristics of teaching were identified from the class instruction of each participant. Both teachers revealed 'Open Inquiry' orientation. This was reflected by their educational goals and beliefs that they should help science-gifted students to grow themselves as scientists by enhancing their inquisitiveness and creative problem solving ability. However, each teacher had shown different teaching orientations such as 'Academic Rigor' and 'Discovery' that seemed to have influence on the level or the range of subject matter covered in the classes. Teachers' science teaching orientations have been changed by their subject of teaching and their experiences in teaching the gifted. In the process, teachers' educational philosophy about gifted education plays an important role in teaching orientation. Based on the ongoing teachers' efforts for enhancing his/her professionalism, the teachers seemed to critically review theoretical knowledge of the science teachers in gifted education through self-reflection on their own teaching methods. When teacher's educational philosophy about gifted education was established and internalized, science teaching orientations in teaching practice seemed to be consistent with his/her goal of teaching.

The self-directed inquiry to improve students' core scientific competency is an important teaching method. Students experience a variety of difficulties in carrying out their inquiry tasks, sometimes fail to produce the desired results, or fail to perform a meaningless inquiry. This study was conducted to identify the causes of difficulties and failures in students' self-directed scientific inquiry. The study involved 16 high school students with experience in science research at science high schools and science-focused high schools. The data collection consisted of in-depth interviews centered on semi-structured open questions. Qualitative data analysis was imputed by finding paragraphs from the interview material that might reveal the difficulties and failures experienced by participants and the reasons for them. The study found that most of the causes of failure were lack of ability, incomplete procedures, and selection of complicated tasks. A variety of cognitive biases, such as overconfidence, planning fallacy, and groupthink, were also analyzed as causes. Based on the results of the study, it is necessary to develop an educational strategy that students can be fully prepared to reduce their trials and errors in a self-directed inquiry maximally.
