In this study, we investigated science teacher's guidance of teaching practice in the perspective of the CHAT. Two science teachers working for schools affiliated with a college of education in Seoul took part in this study. Visiting the entire teaching practice, we observed the processes of guidance and the lessons and collected related materials. Semi-structured interviews were also conducted before, during and after teaching practice. All the data were analyzed by using the constant comparative method. The analyses of the results revealed that student guidance during the lessons was also important. And the curriculum orientation needed to be carried out before teaching practice. The division of labor with pre-service teachers relieved teachers of work burden. Teachers failed to guide assessment of students due to influences of community element such as students who were sensitive to grades. In both cases, teaching practice were so collaborative that those were valuable not only for pre-service teachers but also for teachers and students. Two teachers' activity system showed contradictions due to the lack of specific manuals for guidance and the lack of understanding of pre-service teachers. These contradictions brought about difficulties in their guidance, which in turn led to the difficulties experienced by pre-service teachers during teaching practice. They attempted to resolve contradictions in alternative ways and required standardized manuals for guidance, environments in which teachers could collaborate, and close connections with a college of education. Based on the results, we suggest some ways to improve teaching practice.

This study is to implicate for analyzing the expertise of Education for Sustainable Development (ESD) dealing with science-related social issues by reorganizing educational materials on climate crisis topics and analyzing in-depth class performance preparation and actual class by pre-service science teachers. As a result of the study, it was found that pre-service science teachers have the expertise to analyze the curriculum horizontally and extract subject-integrated elements, but it is difficult to perform convergent science classes by incorporating them into the social problem-solving process in actual classes. In addition, it was analyzed that through this study, pre-service science teachers came to think about the importance of having their own specialized expertise when they become school teachers through preparation for their classes integrating science-related social issues. Through the application of the reciprocal peer teaching applied in this study, giving pre-service science teachers of various expertise an opportunity to experience the process of designing and implementing integrated science classes while sharing their expertise will greatly help them improve their convergence education.

The purpose of this study is to explore the role and effectiveness of argumentation structure and the developmental characteristics of science PCK with Earth science preservice teachers who used argumentation structure as a pedagogical reasoning tool. Since teachers demonstrate PCK in a series of pedagogical reasoning processes using argumentation structures, we explored the characteristics of future-oriented family resemblance-PCK shown by preservice science teachers using argumentation structures. At the end of the semester, we conducted in-depth interviews with 15 earth science preservice teachers who had experienced lesson design and teaching practice using the argumentation structure. Qualitative analysis including a semantic network analysis was conducted based on the in-depth interview to analyze the characteristics of preservice teachers' family resemblance-PCK. Results include that preservice teachers organized their classes systematically by applying the argumentation structure, and structured classes by differentiating argumentation elements from facts to conclusions. Regarding the characteristics of each component of the argumentation structure, preservice teachers had difficulty finding warrant, rebuttal, and qualifier. The area of PCK most affected by the argumentation structure is the science teaching practice, and preservice teachers emphasized the selection of a instructional model suitable for lesson content, the use of various teaching methods and inquiry activities to persuade lesson content, and developing of data literacy and digital competency. Discussed in the conclusion are the potential and usability of argument structure as a pedagogical reasoning tool, the possibility of developing science inquiry and reasoning competency of secondary school students who experience science classes using argumentation structure, and the need for developing a teacher education protocol using argumentation structure as a pedagogical reasoning tool.

For teachers, noticing refers to paying attention to something, indicating they interpret it and how they are willing to react to it in the context of their own instruction. Analysis of noticing features enables us to understand the overall characteristics of the teacher's lesson design, practice, and reflection, which are core agents in the educational design and implementation. This can also be taken to be the basis of education design for competency reinforcement for teachers. Therefore, in this study, the characteristics of noticing shown in teachers' reflections after class design and demonstration were identified. For this purpose, the self-reflection journals of 106 elementary pre-service teachers enrolled in the College of Education in Gangwon-do were analyzed. In particular, the journals were gathered that were written after the demonstration dealing with the change of gas volume by temperature in science class. After designing a noticing analysis frame consisting of the five dimensions 'agent', 'stage', 'topic', 'focus', and 'stance', the frequency and ratio of noticing by each dimension's components were derived. The frequency and ratio of noticing for the dimension of 'focus' were analyzed for the dimensions of 'stage' and 'topic'. The results of the study were as follows. For the dimension of 'agent', the frequency of teacher and student was the highest, and for the dimension of 'stage', inquiry activity was the highest. For the 'topic' dimension, class design according to the teaching strategy appeared most frequently, and in the 'focus' dimension, the cases that did not specify the goal of the class and the competencies to be achieved by the students appeared most frequently. In the 'stance' dimension, description showed the highest frequency. From the analysis of how the 'focus' changes according to the 'stage' and 'topic', it was found that a characteristic focus appeared for each component of the dimension. From these results, the implications of the noticing characteristics of pre-service teachers for the design and implementation of teacher education were discussed.

The purposes of this study are to understand pre-service science teachers' areas of practice concern and reflections on the science classes during student-teaching, and to grasp the factors affecting their concerns and reflections. Four pre-service science teachers participated in this study. Data were collected from four pre-service science teachers' practice journals, instructional materials, and semi-structured individual interviews after their student-teaching. The results are as follows: firstly, the pre-service teachers' concern is focused on the teaching environment and strategies, particularly classroom atmosphere and class management. On the other hand, they pay little attention to science content. Secondly, pre-service teachers' reflections are confined within the limited areas such as classroom management, the proper role as science teachers, or various teaching materials. The level of their reflections is low, mostly concentrated on 'routine' or 'technical' level. Higher levels of reflections, such as 'dialogic' or 'transformative' are not revealed at all. Thirdly, the mentor teachers have the biggest influence upon the concerns and reflections of pre-service teachers during student-teaching.

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.

It has recently be emphasized in science education that lessons that can develop "scientific participation and action" should be implemented to scientifically recognize various problems and respond to them as well as risks that occur in real life. This study aims to analyze the characteristics of scientific participation and action lessons as perceived by the preservice primary school teachers. To do that, the researchers collected and analyzed the lesson plans designed by the preservice teachers based on the achievement standard related to noise for grades 3-4 in 2022 revised science curriculum. Focusing on the stages of "problem recognition," "data collection and analysis," and "implementation and sharing," the results identity the four main characteristics as problem-solving activity, inquiry activity, investigative activity, and activity that encourages practical actions. The two or three features were found to be combinated in a lesson depending on its context. In some cases, only one feature was seen in a lesson. Based on the results, educational implications were discussed in terms of the teaching and learning methods and teacher education for implementing scientific participation and action.

The purpose of this study is to investigate the perception of pre-service elementary teachers on the educational approach to metaverse. Questions about metaverse were asked to 71 pre-service elementary teachers who were taking the course 'Study of Textbooks in Elementary Science II'. The results of analyzing the contents of the questions are as follows. The results and conclusions were presented through numerical analysis and static analysis based on the responses to questions presented using the university's LMS system. First, the level of understanding of the metaverse of pre-service elementary teachers is very high. Pre-service elementary teachers, as the MZ generation, are already living in a very fast IT environment that can be the basis of the metaverse, so it would have been helpful to understand the metaverse. Second, the need for the metaverse of pre-service elementary teachers is very high. There was a tendency to think that the perception of pre-service elementary teachers is because the metaverse has many factors that can provide higher quality education beyond the current educational environment. Third, in the question of applicability exploration in the 'Earth and Space' domain of Pre-service elementary teachers, there have been few cases in which instructional design was planned based on instructional design principles. Based on these results, if the possibility of metaverse application is proposed in the 'Earth and Space' domain, educational contents using virtual space that can transcend time and space will be very necessary. Based on these results, suggestions are made as follows. First, educational content incorporating the metaverse technique based on instructional design should be developed and utilized. Second, financial support should be provided so that the metaverse can be implemented in the educational environment. Third, it is necessary to provide training opportunities for teachers (including Pre-service elementary teachers) to give lectures on metaverse.

In this study, we investigated the perceptions and the educational needs of pre-service primary and secondary teachers on cooperative learning in science. The survey was administered to 102 seniors at the department of science education in three universities of education and 64 seniors at the department of chemistry education in three colleges of education. The results revealed that the pre-service primary and secondary teachers learned the theories and experienced the practices on cooperative learning through various methods in the several subjects, and especially had many difficulties in appling cooperative learning to the demonstrations and/or the actual science classes. The degree of their understanding on cooperative learning was comparatively high, and the perceptions on the advantage/disadvantage of cooperative learning in science, the willingness practicing it, and the outside aids influencing on implementing it were relatively positive. They highly perceived on the necessities of diverse educations related on cooperative learning in science in pre-service teacher education processes. The willingness implementing cooperative learning in science class was significantly correlated with the necessities of diverse educations. These were also significantly correlated with the perceptions on the advantage/disadvantage of cooperative learning in science, the educational assessments on the advantage/disadvantage of it, and the educational assessments on the outside aids influencing on implementing it, respectively. Educational implications of these findings are discussed.
