The purpose of this study is to analyze how pre-service teachers perceive mathematics problems by making good mathematics problems at the elementary school level and applying them to elementary school students. In this study, 86 pre-service teachers enrolled in the second and third grades of A University of Education presented good mathematics problems they thought of. In addition, these pre-service teachers predicted the solution strategies of elementary school students for the proposed mathematics problem and described the teacher's expertise while observing the problem-solving process of elementary school students. As a result of the study, pre-service teachers preferred mathematical problems needed for using mathematical concepts or algorithms, motivation, and open-ended problems as good mathematics problems, and thought that students' in-depth observation and analysis experiences could help improve teachers' problem-solving expertise. In order to enhance teachers' expertise in solving mathematics problems, the researcher proposed for pre-service teachers to observe students' mathematics problem-solving processes, to experience in developing high-quality mathematics problems, and also to distribute high-quality mathematics problems linked to textbook problems.

The purpose of this study is to analyze the experiences of teachers who participated in the development of online science class videos in the context of covid-19, their perception of online science class, and the characteristics of the online science class content developed by teachers. A survey and interviews were conducted with ten elementary school teachers who made online science class videos themselves. Also the characteristics of the online science class were investigated by analyzing the online science class video produced by the participants. As a result, participants in the study recognized the lack of production time, difficulty in filming and editing, concerns over misconceptions, the problem of solving copyrights for existing materials, and the burden of external disclosure. Although it was a teacher who had experience producing online science class video contents, no research participants actively answered the merits of online science class. On the other hand, the study participants cited that the shortcomings of online science classes were that students had fewer opportunities for inquiry and lack of communication or interaction. In particular, these shortcomings were thought to have a great influence on the quality of online science classes, especially in making inquiry classes difficult. Some teachers took a negative view that online science classes could not completely replace face-to-face classes. However, if multiple teachers are presented with supplementary teaching activities that complement the content-based online teaching method, the method of combining online science classes and face-to-face classes is not. Through the analysis of the contents of the online science class, the introduction and arrangement steps of the online science class were similar to the process of the face-to-face science class, but the inquiry step and the conceptual explanation step showed a big difference from the face-to-face science class.

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.

This study analyzed the perception of prospective elementary school teachers in relation to using the history of Korean mathematics. The results of this study showed that the pre-service teachers realized using the history of Korean mathematics more importantly than the history of mathematics. They thought that the contents of the history of Korean mathematics should be increased in mathematics education and pre-service teacher education. The participation experience in teacher education about the history of Korean mathematics had a positive effect on the perception of pre-service teachers. Finally, this paper asserted that teacher education is the key to the teacher perception on and using of the history of Korean mathematics.

The purpose of this study was to determine the perception and understanding of Free Learning Semester (FLS) in home economics teachers and to provide basic informations for effective implement of FLS in future school curricula. Home economics teachers perceived that the objective of FLS was to help students explore their careers and make preliminary decisions. In addition, teachers thought that FLS should be run by active students' participation to find out their dreams and talents. However, teachers felt difficulties in obtaining information or documents related to implementing FLS. Moreover, there were lack of connected activities with local communities to operate FLS. Teachers recognized that it is necessary to receive FLS-related education. Regarding home economics teachers' role in FLS implement, they should provide career education with a perspective of lifelong career and nurture students' capability to lead their lives by themselves. In that sense, FLS should help students find out their dreams and talents, think about their career, set up lifelong career plan through home economics education, and nurture capability to lead their lives. In addition, home economics teachers should provide continuous career education in home economics education at academic semesters.

The purpose of this study is to identify characteristics of secondary school teachers' perceptions and experiences of school libraries and to suggest strategies for its' activation. In order to achieve this aim, the questionnaire survey was conducted for 229 secondary school teachers who participated in K university qualification training in 2017. As a result, they recognize that school libraries are an essential facility and that continuous support and investment are needed. They think that the effectiveness of the school library is very helpful for creating a leisure and cultural life and for stimulating reading atmosphere and education, and this perception is stronger at lower ages. The number of school library use of them is as low as once a month, and the purpose of use is mainly for cultivation and leisure. The discomfort of the school library is mostly due to lack of materials and space for them. In particular, they have a lack of knowledge and necessity about the method of library-based instruction and insufficient preparation time and poor materials. Teachers are highly aware of the need and utility of training, and prefer training with peers. Therefore, it is necessary to develop strategies such as remodeling space and increasing collections for their study and instruction, and foster peer supervision so that they can actively utilize school library in subjects management.

This study involved an investigation of prospective elementary teachers' preconceptions and experiences of diagrams and their ability to draw diagrams in solving math word problems. A questionnaire and two math word problems were administered to prospective elementary teachers who began to taking an introductory mathematics education course. The results from the analysis of their responses to the questionnaire items indicate that prospective elementary teachers appreciate the value of diagrams as tools for problem solving and communication. In addition, prospective elementary teachers have the will not only to teach their future students how to use diagrams but also to encourage them to draw diagrams in solving math word problems. However, the results also indicates that prospective elementary teachers neither use diagrams spontaneously in their math problem solving activities nor have confidence in drawing useful diagrams. Prospective elementary teachers also manifested low scores on the questionnaire items asking whether they were taught how to draw useful diagrams or encouraged by their teachers to use diagrams in their previous learning experiences. The results from the analysis of the diagrams that prospective elementary teachers drew in solving math word problems showed that most of them had difficulty drawing diagrams that represent their reasoning and solving process.

In this study, we investigated teachers' experiences in teaching with the science museum as well as their confidence, their perceptions, educational needs, and their willingness to practice the instructions using science museum. A survey was administered to 225 elementary and secondary school teachers. The analyses of the results revealed that few teachers had training for the instructions using the science museum and not many teachers had experience in teaching with the science museum. Many teachers were also found to have low confidence in teaching with the science museum. Although the teachers had a relatively good understanding of the educational effects, nature and teaching strategies for the instructions using the science museum, they tended to apply the formal views on science teaching/learning to learning with the science museum. The levels of willingness to use the science museum in their instructions and educational needs of the instructions using the science museum were high. They wanted the information about practical aspects to use in the instructions using science museum most. Educational implications of these findings are discussed.

현재 과학교육의 목표는 과학적 소양의 함양이며 이를 구현하기 위해서는 교실에서의 과학탐구의 실현을 필수로 하고 있다. 과학자들이 경험하는 과학탐구는 "실질적 과학탐구(ASI)"라고 하여 필수적인 5가지 탐구요소(문제제기, 자료수집, 설명형성, 설명평가, 발표 및 정당화)를 포함하고 있다. 현재 사용하고 있는 지구과학내용의 교과서를 이 ASI 관점으로 분석하여 5가지 탐구요소의 분포도를 분석하고 이를 이용하여 지구과학탐구를 가르치는 초임교사를 대상으로 탐구에 대한 인식 및 교수실천을 같은 ASI관점으로 분석하였다. 탐구요소 2,3,4 에 해당하는 '증거수집', '설명형성' 그리고 '설명평가'는 빈번하게 나타났으나 탐구요소 1에 해당하는 '문제제기'나 5에 해당하는 '발표 및 정당화'의 기회는 나타나지 않았다. 특히 다른 과학(화학)과목 경우에 '증거수집'이 가장 빈번한 것에 비해 지구과학의 경우에는 '설명형성'이 주를 이루는 것은 지구과학탐구의 특징이라 할 수 있겠다. 또한 교과서 탐구기능은 SAPA로 분석한 결과 일반화, 의사소통, 예상, 그래프작성, 자료해석이 주를 이루었다. 과학적 소양을 함양을 위한 실질적인 과학탐구의 실현하기 위해서는 자유탐구와 같은 부차적인 기회를 통해서 경험하지 못한 ASI의 탐구요소의 기회를 학생들에게 부여해야 할 것이다. 또한 이 연구에 참여한 지구과학 초임교사의 과학탐구 인식 및 교수실천 또한 ASI로 분석한 결과 탐구요소 2번째에 치우친 경향을 보여주고 있었다. 실질적인 과학탐구의 실현을 위해서는 교과서에서 강조되는 탐구요소뿐만 아니라 다른 탐구요소를 경험할 수 있는 자유탐구를 개발하여 실용화해야 할 것이며, 관련 초임교사연수를 통해 초임교사들의 과학탐구에 대한 인식 및 교수실천의 반영 및 이들의 새로운 형성이 추진되어야 할 것이다.

This study was to investigate the perception, performance, and difficulties of process-based assessment for high school mathematics teachers. As a qualitative case study, two in-depth group interviews were conducted with 6 high school mathematics teachers working in Incheon area. The two groups were one with more experience in process-based assessment and the other with less experience. As results, there were differences between the participant teachers' perception of process-based assessment and their actual performance depending on the experience. All six math teachers thought that the process-based assessment was intended to confirm the learner's characteristics, to evaluate the process, and to provide feedback on a regular basis immediately and individually. However, in the practical performance shared by teachers, the purpose of assessment was to create a school record. A group with a lot of experience prepared assessment criteria according to the national curriculum achievement standards, established affective assessment plans, and tried to provide individual feedback on a regular basis. On the other hand, the inexperienced group recorded the affective characteristics discovered by chance and provided temporary and large-scale feedback regardless of the achievement criteria. Finally, we suggested some implications based on the study results.
