This paper aims at analyzing SW club acitivities on the science core high school using information disclosure. Targeting 103 schools across the nation science core high schools, the factors influencing the SW Club was analyzed. And science core high school education plans, business plans and management reports were analyzed in SW club activities. It was the most influencing on the SW club in Creative-Experiential activities organization of computer courses. So computer curriculum reform is urgently needed. SW extra subject activities and funding was having a positive effect. Tuition reimbursement rates was having a negative effect. But academic achievement did not significantly affect. Therefore as many students as possible should be able to assist the SW extra subject activities. And it is required Programs and budget support that reflect the characteristics of local and school. Also, as science core high schools have STEAM education, science, mathematics and technology home economics teachers etc were leading the SW club activities by fusing the their curriculum and SW education. As these activities are consistent with the purpose of SW education, research should be more active autonomic consisting of various teachers.

The purpose of this study was to elucidate elementary school teachers' pedagogical content knowledge regarding the subject of "weight and pressure in water". 6 elementary teachers in charge of the 6th grade were selected for this study. The 7 hour lessons were observed over $15{\sim}20$ days, and a variety of data including scenarios, questionnaires for teachers, interviews of teachers were analyzed. As a result of this study, teachers who had long career histories thought that the purpose of teaching science was to teach the use of science principles, and teachers who had only taught for a relatively short time thought the purpose was satisfying students' curiosity. Most of the teachers felt that the science content knowledge related to buoyancy was insufficient. They had acquired most of the science content knowledge from teaming experiences in middle and high schools. The pre-service teacher education programs didn't help them to satisfactorily acquire the science content knowledge under analysis here. Most of the teachers taught the science lessons according to the order of sequence as shown in the science textbook. They didn't teach the contents that they thought were needed if they were not already included in the science textbook. Only one teacher who had taken science courses in high school managed the science classes freely according to his own thoughts and opinions. From the results of this research, it could be concluded that most elementary school teachers did not have enough pedagogical content knowledge to teach their students effectively.

Assessment of science laboratory environment was conducted with 539 students at middle and high school. Science Laboratory Environment Inventory(SLEI) was used as an instrument. The major findings of this study are as follows. 1. Mean scores obtained on each scale in the actual and preferred version of SLEI were relatively low, particularly on the scale of open-endedness, integration, and material environment. 2. Mean scores obtained on each scale in the actual version were lower than those in the preferred version. Score differences between actual version and preferred one were found to be significant statistically. 3. Boys and high school students perceived their laboratory environment with more open-endedness and less rule clarity than girls and middle school students respectively. 4. Girls preferred student cohesiveness at their laboratory more than boys. Highschool students wanted open-ended environment more than middleschool students. 5. Each scale of SLEI showed significant correlation with the scores of attitudes toward science. Particularly open-endedness was found to account for a significant contribution to the affective outcomes.

The purpose of this paper is to develop a teaching and learning material integrated two subjects Pythagorean theorem and Fibonacci numbers. Traditionally the former subject belongs to geometry area and the latter is in algebra area. In this work we integrate these two issues and make a discovery method to generate infinitely many Pythagorean numbers by means of Fibonacci numbers. We have used this article as a teaching and learning material for a science high school and found that it is very appropriate for those students in advanced geometry and number theory courses.

Natural infection with severe acute respiratory syndrome-coronavirus-2 or vaccination induces virus-specific immunity protecting hosts from infection and severe disease. While the infection-preventing immunity gradually declines, the severity-reducing immunity is relatively well preserved. Here, based on the different longevity of these distinct immunities, we develop a mathematical model to estimate courses of endemic transition of coronavirus disease 2019 (COVID-19). Our analysis demonstrates that high viral transmission unexpectedly reduces the rates of progression to severe COVID-19 during the course of endemic transition despite increased numbers of infection cases. Our study also shows that high viral transmission amongst populations with high vaccination coverages paradoxically accelerates the endemic transition of COVID-19 with reduced numbers of severe cases. These results provide critical insights for driving public health policies in the era of 'living with COVID-19.'

Purpose: The purpose of this study on education and skill of Basic life Support Training in Middle and High School Students. Methods: The Basic life support training courses are taught mostly by Emergency Medical Technician and Paramedic. Sixty five middle school students, Seventy eight High school students and forty six adult received tuition in Basic life support training and subsequently completed questionnaires, test and interviews to assess their theoretical knowledge regarding their likelihood of performing Basic life support training. Under the supervisor, The subjects were evaluated by comparing basic life support education and skill data collected and the education sessions consisted of a 30min video tape. The Basic life support skill sessions used Laerdal manikin, and the data stored from the HeartSim were collected for further analysis. The students were asked to practice what they had been. A statistical analysis was done using the SPSS version 13. Results: Their average age of middle school students were 15.3±1.2 years, high school students (17.3±1.8), and adults(38.3±2.3). The total of 189 subjects were evaluated. The criteria used in the study had the following results First, We found that middle and high school students scored higher than adult. The scores were statistically significant to teach and evaluate the education evaluation showed that the adults scored lower than the middle and high school students. Second, We found that high school students and adult scored higher than middle school students. The scores were statistically significant to teach and evaluate the skills evaluation showed that the middle school students scored lower than the high school students and adult. Conclusion: We found that middle and high school students were superior to adult counterparts in understanding the basic life support education. We found that high school students and adult scored higher than middle school students in the BLS skill training. An expansion of basic life support training to middle and high school students is demanded. The Basic life support skills training seems to be retained between 6 and 12 months. The basic life support training should included in the school education curriculum in school.

The purpose of this study was to investigate pre-service physics teachers' perceptions on the physics education major curriculum. We surveyed 15 junior, and 13 senior college students of physics education major in an university in southern part of Korea. Among them, 24 participants(86 %) took the physics 1 course in high school and 22 participants(79 %) chose the physics 1 in their Korea Scholastic Aptitude Test. The responses showed that the most necessary part in pre-service students' learning was the understanding of high school level physics(36 %), and the understanding of introductory level physics(29 %). In the wish list of courses to be open, high school level physics course was ranked first among seven options by 61 % of respondents. Also, there was some concurrence among respondents in opinion of the necessity for understanding introductory physics. Students felt difficulties in understanding it especially owing to the lack of problem solving skill and comprehension. They added that the sufficient explanation of core concepts should be the first action in the innovative plan. Most participants of pre-service physics teachers hoped to have the revised major curriculum which could help their understanding of high school level or introductory level of physics. However, there was a gap of opinions between the group of students with completion of the high school physics 1 & 2 course and those with non-completion of them. The approach of changing major curriculum with consideration of learners' needs was recommended because the number of students with completion of the high school physics course would probably be decreasing rapidly under these circumstances such as the application of new national curriculum, the reduction of the number of the elective courses in Korea Scholastic Aptitude Test and so on.

In this study, the ways to improve the processes of training, employing and retraining secondary science teachers were investigated by a survey method. Particularly, the following five aspects of the processes were questioned to three major groups of people relevant to school science. A total of 384 responses (from 156 university teachers, 168 secondary science teachers and 64 student teachers) were analyzed through the frequency-analysis and crosstab-analysis of SPSS/$PC^+$ programme. The results of this study can be summarized as follows: (1) middle-school science teachers and high-school science teachers are needed to be trained separately in different systems, (2) the proportions of the faculty members majoring science education and science studies in the departments for science education are needed to be increased, (3) the proportions of the courses related to science education and general sciences in university curriculum are need to be increased, (4) the period of teaching practice in schools during university time should be increased up to five or six weeks, (5) the proportions of science education and general sciences in the examination for science teachers' employment should be increased and the examination should have more subjective type questions, and (6) the programmes for retraining science teachers should have more contents on science education which are directly relevant to school science.

This study examined the differences of academic achievement by social status types through sociometry. This study analyzed 201 students in grade 6 in S elementary school. The social status is classified by 7 (popular, average, rejected, aggressive-rejected, submissive-rejected, neglected, controversial) with academic achievement of each type as dependent variables to figure out the relation between social status types and academic achievement. To classify 5 social status types, a sociometry program developed by Ahn, Ie-Hwan (2007) was used, 2 social status types was classified with experimental condition, and its dependent variable was the score by subjects in the mid-term exam of the 1st semester in 2011. The average values of humanities courses (Korean and social studies) and natural science courses (math and science) were compared by both sexes and 7 social status types. The reference group was average group. As a result, as to male students, N type had the highest score both in humanities courses and natural science courses while C type had the lowest score in both groups. As to female students, P, N, C types had the highest score in both groups with similar range while R type had the lowest score in both groups. This result demonstrates that the academic achievement of students had relatively high relevance with social status. and also, suggestion that how teachers can do to enhance the academic achievement of elementary school students.

The purpose of this study was to investigate the difference of teachers' interaction with their students when teaching science in New York (NY) and in Korea. As part of the 2011 Korean International Teacher Fellows (KITF), supported by the Ministry of Education, Science and Technology (MEST) and the National Institute for International Education Development (NIIED), Korean science teachers observed, for six months, New York's science classes in terms of how teachers interact with their students and how students learn science during science instruction. The participants were 10 science teachers in five middle and high schools that taught Physics, Chemistry, Biology, Earth Science, and Environment Science in NY. The National Board for Professional Teaching Standards (NBPTS, 2003) and Instruction as Interaction (Cohen et al., 2003) were used as an instrument to identify each teacher's teaching and classroom interaction. Several characteristics of science classes in NY were revealed, which are different from Korean science classes. First, science teachers in NY dominantly put more focus on their subject of teaching during science interaction while, Korean science teachers not only teach science but also do counseling to students as a homeroom teacher. Second, science teachers in NY acknowledged the students' individuality and have positive experiences of professional development supported by their school and district more than Korean science teachers do. Third, science teachers in NY sometimes showed limited knowledge about the concepts of science and lack of collaboration with other science teachers. This characteristics may prevent the school from strengthening its subject program and keeping equity across the grade levels and courses.
