The purpose of this study was to find out the effectiveness of metacognitive instruction model on the changes of science concepts, when it was applied to 6th grade students. To do this, students were tested with the achievement of molecules and molecular motion concepts and metacognitive self-regulation test as a pretest Based upon metacognitive instruction model and student's conception, instruction program were developed. This metacognitive strategy Program was applied to the experimental group and expository teaching was applied to the comparison group (followed the order and method in authorized science textbook and teachers handbook). When planned lessons were finished, students were given a post-test to find conceptual change. After six months students were given a test again to find retention effect. There was a significant difference in conceptual change and retention between comparison group and experimental group by treatment at p< .05 level, The difference between comparison group and experimental group was especially significant, when the situation of test item wasn't similar to that of the textbook Metacognitive instruction model was more effective to high group than low group in metacognitive self-regulation level on conceptual change and retention. So the metacognitive strategy Played an important role in conceptual change and retention. And we can recognize that the students who take part in the metacognitive lesson can apply the corrected concept to the other concrete situation because they can understand new concept accurately by metacognitive strategies. And we can guess that high group in metacognitive self-regulation level can team metacognitive strategy easily but relatively low group student have some trouble in learning new strategy.

The COVID-19 pandemic has changed everything, even education. Last year when distance learning was introduced, science teachers faced many challenges to overcome. However, teachers adapted quickly, and in this year, it became the 'new normal'. In this situation, teachers are likely to habitually repeat past practices, but the context of the second year of distance learning is changing constantly, and teachers are asked to interpret the problem occurring in a situation and to adjust their practice for solving the problem with their teacher agency. In this study, we explore the emergence of science teacher agency and factors shaping teacher agency in the second year of distance learning and we focus on teachers' agentic practice that did not follow their past practice without reflection. For this purpose, we mainly analyze the semi-constructed interview of three science teachers. In the first year of distance learning, two teachers maintained their practice, not much different to face-to-face learning. However, one teacher reflected upon herself and started to recognize and solve her problems. Reflection for her practice can support this process. Another teacher changed her practice due to external suggestions, but it evolved her practice to fit the situation better, and her experience of last year helped her to adapt to the change. The other teacher who modified her practice to persist her professional purpose last year was consistently practicing in the second year and collaboration and autonomy can support her. This study shows the teachers' dynamic change of agency and the emergence for the relational interaction between teacher and context.

The modern society is rapidly changing, and accordingly, the required teacher image is changing as well. Middle school students are immature, when they undergo major changes both physically and mentally, and teachers have a great influence. How students perceive the teacher determines the relationship between teachers and students. Therefore, it is necessary to analyze what kind of teacher image middle school students want. The purpose of this study is to analyze the image of a science teacher who prefers and avoids each class situation perceived by middle school students. To this end, 502 middle school students were divided into five classes: class type, class material presentation method, subject instruction method, subject content explanation method, and class atmosphere, and the image of science teacher who prefers and avoids is described in an open format. Concepts presented by middle school students were analyzed through semantic network analysis (SNA). The conclusions of this study are as follows: first, in order to make middle school students interested in science, an inquiry-centered experiment class should be conducted. Second, the change of class by science teacher can change it into preferred science class. Third, student-centered classes should be conducted according to the level so that students can understand. Finally, science teachers continue to strive through communication between science teachers and students, and students and students, and look forward to changes in science classes through this.

This study investigated how pre-service mathematics teaches' experience in microteaching influences their motivations toward teaching behaviors and changes by analyzing their teaching records and class reports. Although respondents planned to conduct various strategies pertaining to motivations, some of them were not used. Also, motivations toward their teaching behavioral changes leaded to positive aspects, but also leaded to negative ones. These findings imply that only two times microteaching experiences would not be sufficient to lead to positive teaching behavioral changes through their motivations. However, pre-service mathematics reported a high level of intention to change their teaching behavior through a comprehensive review process regarding their teaching. Therefore, teacher eduction institutions should develop well structured educational programs and apply them to pre-service mathematics teachers for a better understanding of their teaching and its review through motivations. In addition, providing opportunities for pre-service mathematics teachers to experience various educational programs including microteaching would be necessary for improving their teaching behavior through motivations.

This study examined how the use of learning apps in Zoom-based classes affects learners' English achievement and assessed the efficiency of app use in Zoom-based English classes. The study utilized the English Central (EC) app to induce learners to actively participate in zoom-based classes. To assess the app's efficiency, two rounds of achievement tests and an open-ended questionnaire were administered. The two tests showed that Zoom-based EC app utilization classes positively affected learners' English achievement and the questionnaire revealed that the learners were highly satisfied with using the EC app in Zoom-based classes. The participants praised this approach for "complementing insufficient class content" and facilitating "immediate feedback" (on the EC app), "English practice," and "real-time communication and sharing of opinions" (on Zoom-based classes), describing it as "not boring" and "4 skill training in English." Instructors should strive to efficiently use such new teaching tools in the evolving environment of the untact era.

The purpose of this research is to find factors that affect high school science teachers' class compositions. In this research, we developed the class composing factor analysis framework and we observed teachers' class to figure out the class composing factors. The results from this research were as follows: First, the class composing factor was classified with 'positive motive factor' and 'negative motive factor'. It is the positive motive factor that teachers' voluntary motives operate to teacher for class compositions. It is the negative motive factor that outer demands operate to teacher for class compositions. Second, both positive and negative motive factors were shown in all the steps, which included preparing a class, progressing a class, and after a class. Also, according to the circumstances, each factor changed. Minimizing and overcoming negative motive factors will lead to positive interaction between the teacher and students. It will also increase a teachers' achievements in class and maximize the effectiveness of class. Therefore, it is expected that this will be a great help for teachers to enhance their teaching professionalism.
