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 aims to describe, explain, and understand the process of coteaching instruction in which two pre-service science teachers plan, perform, and reflect the instruction in a university lecture. Pre-service science teachers exchanged their perspectives on teaching, selected the learning model and the science content to teach, and prepared the teaching material together. They performed the coteaching using the lecture room effectively and exchanging the role of leading the instruction. The professor and other pre-service science teachers participated to the coteaching instruction directly or indirectly with the role of students or lesson critics, and shared the evaluation and reflection on the instruction. We discussed the meaning and implication of the coteaching instruction on the secondary education field, the science teacher education, and the science education.

The purpose of this study was to find out what pre-service teachers' views of as a good science class in evaluating class demonstrations. The study was conducted on 32 students in the second year of college who are attending teacher training schools located in central region, Korea. 32 pre-service teachers demonstrated the class with a group of 2 students, and a total of 16 lessons were demonstrated. They also evaluated the class by participating in 15 lessons except ones own class. Therefore all the collected evaluation papers were 480 sheets. This study analyze this evaluation paper and find out the good science class that earth science pre-service teachers think. As a result, the pre-service teachers' views of good science class analyzed by 3 categories. The three categories were 'Highly Engaged Instruction', 'Well-structured class design', and 'Qualitatively superior class materials'. In other words, the pre-service teachers' views that well-structured class design and active interaction were the requirements of good science class. This study confirmed that pre-service teachers can draw images of good science class through experience of class demonstration and class evaluation.

As a case study on the use of mentoring as a method of improving novice teachers' teaching professionalism in secondary science-gifted education, this study investigated the characteristics of mentoring science instructions for science-gifted students at the plan, performance, evaluation, and post-mentoring stages of the classes. One mentor and two mentees were selected, and mentoring in each mentee's instructions was conducted during nine classes over three times. We observed the total classes, and analyzed taped videos, the materials, the transcripts for mentoring and in-depth interviews, and field notes. The analyses of the results indicated that the characteristics of mentoring instructions, at the planning stage of the classes, exhibited the construction of more systematic classes, the escape from the schema that science instructions for science-gifted students were instructions using somewhat difficult experiments and the uses of diverse teaching strategies, the influence of the psychological burdens on developing science-gifted education programs, and the increase of the time preparing the classes. At the performance stage of the classes, the characteristics included the improvement in the quality of the classes, the influence of the psychological burdens on teaching the classes, and the inducements of some confusion on performing them. At the evaluation stage of the classes, the characteristics included the provision of the opportunities in deeply reflecting my own classes, and the provision of the practical power for improving the classes. Finally, the characteristics at the postmentoring stage could be attributed to the increase of mentees' self-confidence about their instructions and some development of mentors' teaching professionalism/mentoring skills.

This study investigated the current science teaching evaluation system implemented in schools and directions for improving teaching evaluation using literature review, survey, and teacher interview. The first part of this paper analyzed the types, roles, and major issues of the current science teaching evaluation. In-service teachers argued that the current teaching evaluation system was discredited because of the bureaucratic procedures of teacher performance review, showcase classrooms, teachers' views on classroom as their own personal space, low ratio of teaching component in the current teacher evaluation, untrained evaluators, and the absence of professional teaching standards. The second part of the paper investigated the need for a formative teaching assessment, an ideal type of teaching assessment, and the role of participants in the teaching evaluation processes. The way forward, therefore, is to start not at the level of the administrative superstructure but at the level of teachers who will assume responsibility for developing standards of practice as the basis for evaluating their own work and improving their own professional learning to provide quality assurance.

The teacher plays important role at students' achievement. This study analyses science class by pre-service science teacher. An survey tool for analysis of science class was composed of the lesson, student behavior, teacher behavior and questioning techniques. Pre-service science teacher analyzed the science class of 100 science teacher. The results of this study showed that pre-service science teacher analysis that current science class did not focused on inquiry-oriented. The score of science class did not statistically significantly difference by science teacher's characteristics as gender and age. Also, they analyses that science teacher use concept-oriented and teacher-oriented method.

The purpose of this study is to investigate the possibilities of science ethics education with history of science (HOS) and to develop its teaching and learning model for secondary school students. A total of 72 cases about science ethics were extracted from 20 or more HOS books, journal articles, and newspaper articles. These cases were categorized into 8 areas, such as forgery, fabrication, violation of bioethics in testing, plagiarism and stealth, unfair allocation of credit, over slander, conjunction with ideologies, and social responsibility problems. The results of this study are as follows. First, research forgery, occurring in the process of the research, was the most frequent in HOS. Second, we developed eight teaching lesson plans for each area. Third, we proposed a teaching and learning model based on the developed lesson plans as well as related teaching and learning models in the fields of science ethics education, ethics education, and history education. Our model has five steps, 'investigating-suggesting casesclarifying problems-finding alternatives-summarizing'.

The purpose of this study is to investigate secondary science teacher's concepts of good science teaching. To do these, I have developed a questionnaire composed of 32 good teachings on education content, instructional method, instructional environment and atmosphere and assessment categories. 136 secondary science teachers have participated in the questionnaire and were requested to show agreement. Additionally, they were requested to describe the best science teachings that they have experienced. Results are as follows: First, the best science teaching that science teachers thought is a teaching that is in full accord with students' level in education content category, a teaching with an energetic interaction in instructional method category, a teaching in a trustful atmosphere in instructional environment and atmosphere category, a teaching in which students could learn something through a teaching-related assessment in assessment category. Second, secondary science teachers thought that a self-directed learning, a differentiated instruction and a teaching with diverse materials are not important factors in good science teaching. Third, there is a difference between good teaching that secondary science teachers have conceived and good teaching that they have experienced. It shows that science teachers did not precisely understand what good science teaching is. Additionally, I discussed the need of finding a case on good science teachings and a support of an interaction-focused teaching.

Recently, there has been a dramatic increase in the number of cases that have formed and operated teachers' learning communities through cross-curricular consulting at the school level. The purpose of this study is to explore cross-curricular instructional consulting as an activity of teachers' learning communities at the school level, and investigate the effect of cross-curricular instructional consulting on middle school science teaching. We analyzed features and limitations of cross-curricular instructional consulting revealed in three case studies in middle school, including open classes and instructional consulting sessions, and conducted additional instructional consulting on the same videotaped science classes with science experts from outside. According to the results, science inquiry experiments are often replaced with text reading and interpreting, students' misconceptions and exact scientific representations are ignored, and the goal setting as well as class coverage has been questionable and disputable in science classes resulted from cross-curricular instructional consulting. Discussed in the conclusion are the necessity of cross-curricular instructional consulting in middle school, and ways to overcome limitations of the method of cross-curricular instructional consulting, including alternatives to a praise-only policy in cross-curricular instructional consulting, ways to use cross-curricular instructional consulting without compromising the subject's essence, and ways to improve the undue authority of consultants.

The purpose of this research is to explore types of pedagogical content knowledge (PCK, hereafter) for effective science teaching. In this research, we explored three science teachers' PCK on light, who were effective in teaching the topic with particular students. The data analysis consisted of identifying the three teachers' unique PCK and ways to improve each teaching episode through the teacher meetings. These analyses, which consisted of verbal exchanges among the participants, were identified on the basis of our understanding. Using grounded theory methods, the types of science PCK drawn from this research are: (1) teaching through curriculum reconstruction, (2) teaching to help students build their own explanation models about surrounding nature, (3) teaching for learning the social language of science, (4) teaching to motivate students' learning needs based on relevance of science to students, (5) teaching through lowering students' learning demand by providing scaffolding, (6) teaching based on the teacher's understanding of students, (7) teaching through inquiry with argumentation, (8) teaching through reification of abstract science concepts, and (9) teaching none marginalized science. Common features of science teachers with quality PCK and their professionalism in teaching are discussed.
