The purpose of this study is to develop a measurement tool quantifying the degree of high school students' scientific experience. Based on previous studies, we divided the factors that compose school scientific experience into three categories: general activity experience, scientific inquiry experience and laboratory apparatus experience. While, outside of school scientific experience was divided into general activity experience, interesting activity experience and field trip experience. Items consisting each factor were selected from scientific experience measurement tools used in previous researches, most frequent answers showed in open questionnaire about scientific experiences, and exploratory analysis of textbooks. After the measurement tool developed by pilot-questionnaires and previous researches were preliminary tested and then was secondarily tested for a group of 413 high school students. The content validity and construct validity of the measurement tool was evaluated by two school teachers and two experts in science education and by factor analysis, respectively. The reliability of the tool was estimated with Cronbach Alpha. The results of validity and reliability revealed that the tool was appropriate for measuring scientific experience.

This qualitative study investigated how a music therapy program was experienced by juvenile offenders of school violence who were under a conditional suspension of indictment. Six adolescents participated in 12 consecutive weeks of group music therapy sessions, and were interviewed individually based on open-ended questions addressing key constructs of self-determination theory, which are autonomy, competence and relatedness. Using this framework, data was deductively analyzed using a modified grounded theory. The analysis also investigated how such impact of music therapy transferred or expanded to their everyday life. The analysis revealed that the properties of autonomy included making choices of songs and instruments, deciding how to play, and expressing opinions about music. Competence was associated with developing skills on musical instruments, creating own music, concentrating on their own project, and demonstrating their abilities. Relatedness were related to collaborating, exchanging opinions, and playing a part in musical projects. In addition, it was found that they also experienced shifts in consciousness and behavior, expanded self-awareness, and mutual exchange and group support. Lastly, it was revealed that the positive emotional and behavioral changes they experienced in music also appeared in their school life.

Education researchers have been continuously interested in the teacher's ability to design lessons and conducted various studies in order to improve the teacher's professionalism in determining the quality of school instruction. So, this study explored the change of instructional design through the lesson reflection of pre-service mathematics teachers who participated in practicum settings. As a result, in the lesson plan prepared by pre-service mathematics teachers, the motivation to induce learning in the introduction stage, to present the learning contents in the development stage, and to reconstruct the formative evaluation of the closing stage was the highest rate. And the categories of the reconstructed contents appeared intensively in terms of curriculum contents and teaching and learning methods. This result can be attributed to the lack of experience in designing and performing lessons by pre-service mathematics teachers, so it suggests that the opportunity to design and conduct classes that take into account the practical aspects of education should be provided in the preparation process for pre-service mathematics teachers.

This study explored the changes in the elementary science teaching expertise of teachers who participated in an in-school professional learning community for elementary science instructional research. Six elementary school teachers from grades 4, 5, and 6 at an 18-class S elementary school in a medium-sized city in Chungcheongbuk-do conducted collaborative instructional research on elementary science lessons as part of an in-school professional learning community, which was held 26 times over 7 months in 2020. During the professional learning community, video and audio recordings of the activities, research lessons, course materials, and professional learning community reflection activities were collected for analysis. The collected data were analyzed using qualitative research methods; data processing, reading, note-taking, description, classification, interpretation, reporting, and visualization; and the instructional professionalism elements were extracted based on the instructional professionalism framework. In the early professional learning community activity stages, the participating teachers first discussed their teaching perspectives, their experiences, and their goals for teaching science, which resulted in a selection of research questions. The teachers then collaboratively designed and implemented research lessons for each grade level, after which lesson reflections were conducted. The teachers' abilities to engage in qualitative reflection on the research questions improved after each reflection iteration. It was found that this professional learning community collaborative lesson study experience positively contributed to teaching expertise development. Based on the study findings, the implications for using professional learning communities to improve elementary teachers' science teaching expertise are given.

The "Figure Equation" chapter of current high school curriculum prevents students from relating the concept with what they studied in middle school Euclidean geometry. Woo(1998) concerns that the curriculum introduces the concept merely in algebraic ways without providing students with opportunities to relate it with their prior understanding of geometry, which is based on Euclidean one. In the present study, a sequence of GeoGebra-embedded-geometry lessons was designed so that students could be introduced to and solve problems of the Analytic Geometry by triggering their prior understanding of the Euclidean Geometry which they had learnt in middle school. The study contributes to the field of mathematics education by suggesting a sequence of geometry lessons where students could introduce to the coordinate geometry meaningfully and conceptually in high school.

The purpose of this study was to explore the meaning of the teaching experience of middle school physical education teachers, listening to in-depth statements related to teaching experience based on the physical education teacher's teaching identity, and analyzing the meaningful content and meaning structure found therein. The study participants were four current middle school physical education teachers. The research method used Colaizzi's phenomenological method to analyze the meaning structure through in-depth interviews with research participants, group interviews, additional interviews, and field records. In order to solve the research questions, the interviews were conducted as semi-structured interviews, and the individual interviews were terminated when there were no more duplicate cases or similar phenomena related to teaching experience. As a result of the study, the meaning of experience was constructed based on narrative statements through interviews with research participants, and a collection of 2 items, 6 categories, and 12 themes were extracted by exploring concepts from the constructed meaning. The reasons for going into the teaching profession were categorized into 'motivation' and 'beliefs', and the meaning of teaching experience was categorized into 'mission', 'relationships', 'exhaustion', and 'overcoming'. In conclusion, although the research participants faced numerous difficulties, they experienced challenges and recovery by pursuing the joy and value of sharing within the school community.
