In this case study, we investigated teaching strategies of science teacher's teaching in science museum. Two secondary science teachers who completed a teacher training course on teaching in science museums participated in this study. We conducted interviews about their perceptions on teaching in science museum and their teaching plans before teaching. Then, we observed and recorded their teaching practices in the science museum throughout one semester, and collected all of the teaching materials. The interviews were also conducted after every lessons and at the end of the semester. For the analysis of teaching strategies, we used a framework that was revised from the framework for museum practice (FMP). The analysis of results revealed that the teachers understood the significance of planning the activities in a series of pre-visit, during-visit, and post-visit, so that they structured their teaching as continuous activities, not as an one-time event. However, they showed differences in the extent of connecting the activities with the national science curriculum according to their teaching objectives. In addition, there were differences in strategies such as promoting social interaction, evoking students' curiosity and interest, providing students with choices and control, and inducing engagement and challenge depending on each teacher's perceptions and experiences on teaching in science museum. These results suggest that science teacher education for the professional development of teaching in science museum should systematically provide knowledge and experiences on teaching strategies based on appropriate perceptions on teaching in science museum.

This study aims to understand science education conducted in North Korea by analyzing the PCK components shown in two science teacher's guidebooks: (1) Guidebook for 1st grade elementary school and (2) Guidebook for 1st grade middle school. These were published after 2013, when "the first 12-year Universal Compulsory Curriculum" was implemented in North Korea. The analysis shows that both elementary and middle school guidebooks had the highest percentage of content in "Knowledge of Subject Matter", followed by "Knowledge of Instructional Strategies in Science" and "Knowledge of Science Curriculum". On the other hand, "Knowledge of Assessment in Science" and "Knowledge of Students" were significantly low in content. Within the "Knowledge of Subject Matter", both elementary and middle schools had the highest proportion of content in "Concepts and Theories", along with "Experiments and Inquiries" that was also significantly higher than other PCK components. Science teacher's guidebooks in North Korea advocates constructivist teaching style by using "discussions" as the main activity when conveying scientific concepts and theories to students or conducting scientific inquiry classes. Furthermore, "Knowledge of Instructional Strategies in Science" was mainly focused on guiding the "Instruction sequence and method" from the "Topic-specific Strategies", while only a small part of the "Subject-specific Strategies" was being presented. Also, Science teacher's guide books in North Korea included only a few theoretical elements of science education in both the general outline and the particular sections of guidebooks. "Knowledge of Science Curriculum" was mainly composed of "Lesson Objectives" with some inclusion of "Vertical Articulation" and "Horizontal Articulation". "Knowledge of Assessment in Science" and "Knowledge of Students" accounted for a small portion compared to the science teacher's guidebooks in South Korea.
The purpose of this study is to examine not only students' cognition in the mathematical error-finding activity of the concept of irrational numbers, but also the students' learning stance regarding the use of errors and a teacher's questioning strategies that lead to changes in the level of mathematical discourse. To this end, error-finding individual activities, group activities, and additional interviews were conducted with 133 middle school students, and students' cognition and the teacher's questioning strategies for changes in students' learning stance and levels of mathematical discourse were analyzed. As a result of the study, students' cognition focuses on the symbolic representation of irrational numbers and the representation of decimal numbers, and they recognize the existence of irrational numbers on a number line, but tend to have difficulty expressing a number line using figures. In addition, the importance of the teacher's leading and exploring questioning strategy was observed to promote changes in students' learning stance and levels of mathematical discourse. This study is valuable in that it specified the method of using errors in mathematics teaching and learning and elaborated the teacher's questioning strategies in finding mathematical errors.

Secondary schools in Korea have been faced with with several critical problems with regard to science education, with one of the most fundament problems being associated with secondary school science teacher education and in-service training. Therefore this study, which is a part of project for the improvement of science teaching in secondary schools, had its purposes to inquire into the following are as. ${\circ}$systems for science teacher education ${\circ}$curricular contents and its operations of science teacher education ${\circ}$systems for in-service teacher training and its operations ${\circ}$analyses of problems associated with science teacher education and in-service teacher training. In order to fulfill these objectives this study used methods of literature review, survey, and interviews. The major findings are as follow: ${\circ}$curricular hours of subject matter education are not sufficient for competent science teacher. opportunities for self-training in major are as are seldom given to the most of the science teachers ${\circ}$systematic organization for in-service traings is in urgert need. In addition to there-findings strategies for improving science teacher education and in-service trainings are suggested in this paper.
This study aims at investigating Korean EFL students' writing strategies through their rhetorical patterns and meaning-making for a writing task in an English writing classroom at a Korean university. The participants were the students and teacher in the course, and the data comprised nine pieces of students' opinion writing and interviews with the teacher. To analyze the data, a 'Claim-Support' pattern was adopted. The findings show that most students, 89%, demonstrated the same or similar elements in the 'Claim-Support' pattern for their textual structures and many parts of the meaning-making in their writing were originated from the textbook. These findings reflect that the students pursued the strategy of 'accommodation' in order to succeed in their academic writing regardless of the teacher's intention which focused on creativity and imagination in writing. The conclusion suggest that the students tend to establish their own ways of strategy to cope with the recontextualized setting for writing in English.

This study aimed to analyze cases of online class design by pre-service science teachers to identify the teaching strategies employed for online classes. For this purpose, the real-time online class lesson plans of 12 pre-service science teachers, who had experienced education utilizing online teaching tools for a semester, were collected and analyzed. The pre-service science teachers considered all the elements that were essential in traditional face-to-face class designs, including prerequisites, statements of learning objectives, stimulating motivation, teaching and learning methods, wrapping up, teacher-student interaction, and assessment. They devised teaching strategies that could overcome the limitations of online teaching and were not feasible in face-to-face classes for each element. Additionally, they were considering new instructional strategies tailored to the online teaching environment, such as creating a conducive environment for using online teaching tools and strategies related to checking the online teaching environment. However, for statements of learning objectives, stimulating motivation, and wrapping up, most of the pre-service science teachers predominantly utilized teaching strategies from traditional face-to-face classes, especially those involving the presentation of visual materials through online tools. Student-centered approaches were rarely implemented in stimulating motivation or wrapping up. These findings imply that one semester of exposure to the utilization of online teaching tools may be insufficient in teacher education. Thus, there is a need for a continuous and expanded educational program on the utilization of online teaching tools as part of pre-service teacher education.

The purpose of this study is to figure out the characteristics of teacher's scaffolding that can promote the social construction of scientific models by analyzing a teacher's scaffolding that actually promoted the social construction in a real classroom context, so that we can better understand the teacher's scaffolding. For this study, a total of 32 middle school students and their science teacher in Seoul were observed and videotaped. The level of social construction were categorized in four stages. We divided the teacher's scaffolding by whether the level of social construction has changed or not, and analyzed teacher's scaffolding in each group. Teacher's scaffolding were categorized based on its object, purpose and means. The object were categorized into two types; small-group and individual. The purpose were categorized into two types; process-help and product-help. The means were coded into Diagnostic strategies(Reading, Listening, Questioning), Checking diagnosis and Intervention strategy(Instruct, Explain, Hint, Confirm). The result show that teacher's scaffolding is helpful in the social construction of scientific models when it supports small-groups more than individuals, and process-help more than product-help. It also shows that in diagnostic strategies, questioning and listening are effective. Finally, using checking diagnosis promoted interactions among students and a 'confirm' intervention strategy should be avoided because it has no positive effect on changes in the level of social construction. This study provides the features of the teacher's scaffolding that promotes social construction of scientific models in middle school classes.

This study is to explore degree of childcare teacher's teacher efficacy and the factors influencing of knowledge related to disease, self-esteem and job stress on teacher efficacy of those surveyed. A descriptive study was conducted with a survey of 257 childcare teacher in G city. The data were analyzed with t-test, ANOVA, Pearson's correlation coefficients and Hierarchial multiple regression using SPSS WIN/21.0 program. The mean score of the was teacher efficacy $78.70{\pm}8.28$. The teacher efficacy was had a positive correlation with self-esteem (r=.493 p<.001) and a negative correlation with job stress(r=-.247, p<.001). But the teacher efficacy was had a not correlation with knowledge related to disease. (r=.046, p=.257) The result of the hierarchial regression indicated that self-esteem, job stress and position explained 30.0% of variance in teacher efficacy. The result suggest that it is necessary to interventional strategies to promote teacher efficacy for childcare teacher in childcare centers to improve teacher efficacy.
This study investigated the effect of student-perceived teacher's calling on student's well-being and the mediating effects of student-perceived emotional support and adaptive cognitive emotion regulation strategies. We analyzed data from 494 high school students in South Korea by using structural equation modeling. The results showed that student-perceived emotional support from the teachers mediated the relationship between student-perceived teacher's calling and adaptive cognitive emotion regulation strategies. Also, adaptive cognitive emotion regulation strategies mediated the relationship between student-perceived emotional support and student's well-being. Furthermore, student-perceived emotional support and adaptive cognitive emotion regulation strategies sequentially mediated the indirect positive relationship between student-perceived teacher's calling and student's well-being. Based on these results, implications and recommendations for future research are discussed.
In this study, we analyzed the PCK components in the materials units of the third and fourth grades of the Korean government-authorized teacher's guides for elementary school, developed in the 2015 revised national curriculum. The results showed that the PCK components were presented in a relatively balanced manner compared to the teacher's guides for middle school. Knowledge of the subject matter accounted for the highest proportion, and knowledge of instructional strategies in science accounted for a higher proportion than knowledge of the science curriculum. The knowledge of assessment in science showed the greatest deviation among publishers, and knowledge of students tended to show the lowest. By subcomponents, experiments and inquiries had a higher proportion than concepts and theories. The ratio of horizontal articulation was lower than that of vertical articulation or lesson objectives, and lesson objectives were presented in various ways, such as in core competencies and achievement standards for science. As questioning was emphasized, teaching strategies and questioning appeared at a similar rate. Motivation and interest, misconceptions were linked to teaching strategies and questioning. In some cases, assessment items and assessment criteria were presented at each level, and various PCK components were linked to these two components. Components with relatively large differences among publishers were supplementary or in-depth concepts, inquiry in textbooks, instruction sequence and method, subject-specific strategies, and assessment items. From the results, the implications for the development of teacher's guides were discussed.
