The purpose of this study is to analyze pre-service science teachers' pedagogical content knowledge. For this study, two senior education students were selected. The data of this study were collected through interviews, CoRe questionnaire, and classroom observation recordings during the period of student-teacher practice. Data were analyzed using the constant comparative method. The results indicated that the two pre-service science teachers had low level pedagogical content knowledge. Two pre-service science teachers' knowledges of science curriculum were different from each other. Orientations toward teaching science shifted to undesirable direction after the experience of a student-teacher's practice-teaching. Their subject matter knowledges were imperfect. They also had low levels of knowledge of students' understanding.

With the growing acceptance of the educational benefits for the use of robot- based teaching, their use in classrooms is increasing. However, the vast majority of studies taking place are based within normal classroom environment. Therefore, this study was focused on the adaptations that need to be made for the use of robot-based teaching within a special-needs environment, specifically a program for pre-service teachers of a special needs Elementary school. The results indicate robot-based teaching has a place within special education and it is hoped that this study will spur further investigation into the field.

Rapid development of educational technology requires fundamental changes not only in the form of instruction and role of teachers in school education but also in the competency development of students. Specifically, the emergence of new technologies such as makerspace, virtual reality (VR), and robotics has made it more challenging for teachers and students in the 21st century. However, even with the argument for the changes, less has been discussed about how much in-service teachers are aware of and how they are preparing for such changes. Therefore, this study intends to explore what would be required to students and teachers, and for instructional changes with more technologies available through the lens of elementary school teachers. The study results suggest, similar to previous studies, in-service elementary teachers recognize that student competencies such as creativity, collaboration, communication, and problem-solving skills are important. They also perceived that teacher change in role and attitude, and for instructional method and classroom culture are crucial as catalysts of change. Unique and interesting finding from this study is about the importance of nurturing digital citizenship in technology-infused learning environment. The digital citizenship has been less highlighted in the past, but this study revealed it should be treated as a priority.

The purpose of this study was to analyze the professionalism of elementary school teachers and to draw out factors which elementary teachers should try to improve their professionalism for environmental education. For the study, both Quantitative analysis and qualitative methodologies were applied: First, randomly selected 483 elementary teachers from Seoul and Gyeonggi self responded to 5 evaluation areas by Hungerford et al. (1994) to evaluate their environmental education professionalism through the use of five point Likert scale. Second, 2 elementary teachers' environmental classes were observed for the purpose of analyzing strengths and weaknesses in classroom instruction, and then the results of self-evaluation on environmental education professionalism and teacher professionalism as shown in the classes were compared. It was found that 483 elementary teachers including 2 teachers fer analyzing classroom instruction who performed a self-evaluation gave themselves mid-scores on the Hungerford et al.'s 5 evaluation areas. However, the result of self-evaluation did not correspond with the result of actual class observation and teacher interview. That is, the actual environmental classes conducted by 2 teachers did not seemed to reflect the evaluation areas which were the foundation of the study: the conceptual awareness, the investigation & evaluation, environmental action skills, and educational application. The results of this study can be used as the basis reference to develop teaching-learning program and in-service programs for professional development of teachers for successful application of environmental education in elementary school classes.

Recently, many universities have used various electronic attendance systems such as NFC, QR code, Sound-QR, Bluetooth BLE authentication, and face recognition to process attendance. However, existing methods have various problems such as attendance errors due to deformation of authentication signals, mis-recognition attendance from outside the classroom, and difficulty to process seat absence during class. Therefore, this study proposes a high-frequency signal-based electronic attendance system to solve these problems and manage more accurate electronic attendance. As the high-frequency signal replaces the BLE signal, and the transmission range of the signal is limited to the classroom, and the signal value can be immediately changed if a change of the signal is needed. To verify the performance of the proposed system, we conducted a comparative experiment with the Bluetooth based electronic attendance system, and as a result, the proposed method showed high accuracy. Thus, the proposed method will be a useful service that can be immediately used in smart device-based electronic attendance system.

This study is the field of mathematics education on the assumption that they can extend outside the classroom. Recent mathematics education is increasing the importance of field experience and various activities based on real-life math education. Thus, it is necessary to consider this situation in pre-service teacher's education. The purpose of this study is to apply the 'Mathematics Field Trips Activities' in the pre-mathematics teacher education. So the specific case of 'Mathematics Field Trips Activities' was analyzed. Mathematics teachers conducted preliminary exploration activities on the historical cultural property which were effective in the following four aspects. First, cognitive effects and second, definitive effect. Third, cultural-mathematical effect. Fourth, the effect on improving math class. Finally they were summarized and divided into classes target content knowledge and teaching knowledge both sides. As a result, the 'Mathematics Field Trips Activities' were found to have significant effects on pre-service math teacher. Finally, ongoing research is needed to settle into a new teaching and learning methods.

Nowadays a lot of schools carry out open education and the school libraries have to seek the ways how they can participate efficiently in the instructional design process in the system of open education. For these purposes, a spatial relationship of school library and the process of cooperative program planning and teaching is investigated with a case study. Cooperative program planning and teaching is a school library service program which has to be developed as an instructional program related to classroom teaching. However the tendency is that teacher-librarians are not active to do it in the open education system.

Prospective teachers need to have an opportunity to critically examine their initial perception with regard to effective mathematics instruction during the teacher education period. This study analyzed the perception in relation to good mathematics instruction by a total of 265 prospective teachers from four institutes for elementary teacher education using a survey. The results of this study showed that the pre-service teachers regarded learner, teaching and learning method, selection of content, and construction of curriculum as important for high-quality mathematics instruction. However, they revealed relatively low levels of agreement against the importance of instructional materials, classroom environment and atmosphere, and assessment. On the basis of teachers' perception on each element of effective mathematics instruction, this paper raises issues for discussion and includes some implications for teacher education.
