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.

This study aims to investigate the gaze patterns of two expert and two novice teachers in one hour of lecture type class. Teachers recruited from the same middle school conducted the class each, wearing an eye-tracker. Gaze rate and gaze movement pattern were analyzed. The scene where teachers faced in the classroom was categorized into three zones; student zone, material zone, and non-teaching zone. Student zone was divided into nine areas of interest to see the gaze distribution within the student zone. Expert teachers showed focused gaze on student zone while novice teachers' gaze rate was significantly higher at the non-teaching zone, compared to expert teachers' one. Within student zone, expert teachers' gaze spread to the rear areas, but novice teachers' one was narrowly resided in the middle areas of the student zone. This difference in gaze caused different eye movement pattern: experts' T pattern and novices' I pattern. On the other hand, both teacher groups showed the least gaze rate onto the left and right front areas. Which change is required to teachers' gaze behavior and what must be considered in order to make effective teacher gaze in the classroom setting were discussed.

The purpose of this study was to investigate the differences of Middle and High School Students' influential groups in putting on clothing according to their delinquency and demographic variables. My subject was 1050 middle and high school boys and girls who are resident in Seoul; sample groups were selected, considered their resident area, gender and the kind of school. The results are as follows: 1. The exemplary group was most regarded the opinion and evaluation of teacher, father and mother and followed the clothing of teacher. Compared with the exemplary group, the delinquent group was most regarded the opinion and evaluation of other and same sex friend and tended to follow their clothing style. Besides, the delinquent and middle groups were most regarded the opinion and evaluation of seniors and tended to follow their clothing style. The mass media star was most modelled by delinquent group, following by middle and exemplary groups. 2. Schoolgirls were more regarded the opinion and evaluation of same sex friend and senior and were more remarkable to follow the clothing style of their parent, friend, senior or mass media star than schoolboys. The students who did well at school more were regarded the evaluation of father, mother and same sex friend than those who did commonly or poorly. As for the exemplary group, the poorer a student did at school, the more he/she tended to follow the clothing style of mass media star, but on the contrary, as for the delinquent group, all students tended to follow the clothing style of mass media star regardless of their academic record. And there was no significant difference according to social status in important others and model group.

The purpose of this study is to investigate middle school science teachers' pedagogical content knowledge for science practice-based instruction developed by five middle school science teachers in a teacher learning community. Science teachers in this study collaborated to examine lesson plans and reflect on teaching practice and collaboratively analyzed science curriculum, discussed video-recordings of teaching practice, and discussed to design detailed and elaborated lesson plans. Data collection consisted of pre and post questionnaire and interview, audio-recording of teacher discussion in a teacher learning community for one year, lesson plans, teacher written reflection, and video-recording of teaching practice. Data analysis reveals that science teachers developed pedagogical content knowledge for science practice-based instruction that consists of eleven sub-components of knowledge of science curriculum for science practice, knowledge of science practice-based instructional strategy, knowledge of students' science practice-based learning, and knowledge of science practice-based learning assessment. Science teachers in this study developed highly structured pedagogical content knowledge for science practice-based instruction.

The purposes of this study were to develop and implement a teaching strategy that reinforced teacher-student interaction for middle school first grade science and investigate the impact of the teaching strategy on student comprehension of scientific concepts, logical thinking ability, and science-related attitudes. 200 students attending a co-ed middle school located in Gyeonggi province were selected for the study and divided into an experiment and control group each consisting of 100 pupils. The teaching strategy reinforcing teacher-student interaction was applied to the experiment group, while conventional teaching, teacher-led lecturing, was carried out on the control group. To accomplish reinforced teacher-student interaction teacher asked students diversified questions and gave delayed feedbacks that deliberately focused on thought provocation. Results showed that the developed teaching strategy was effective in improving the students' logical thinking ability(p<.01). However, no significant differences were found in student comprehension of scientific concepts and science-related attitudes between the experimental and control group(p<.05). It was determined that more sound research is needed to develop and apply a lesson plan based on the teaching strategy used in this study.

This study aims at proposing some reform measures for the middle school grouping system in Gwangju Metropolitan City, which is divided 86 middle schools into 10 clusters and 3 school districts. In doing so, it analyzes the present status of educational environment and student walking distance in each school district such as the number of student per teacher, the student density, the school size and the gender ratio in class. And it conducts a survey of 5,363 middle school students, 3,966 parents and 1,007 teachers, also evaluates their satisfaction levels and needs with the student allocation system. As the result of the survey and data analysis, it finds out some problems in some school districts which are gender imbalance in class, the preference for private middle schools and inconvenience in commuting to school. To solve these problems, the study suggests the better alternatives to replace the current system. Firstly, to set up the basic fundamental principles detailed in 3 action plan, which emphasize the adherence to a close-range allocation, the appropriate size of school and class, and the equalization of educational environment. Secondly, to establish the information system for managing the school district in order to be more objective and transparent. Finally, it gives a concrete proposal which divides the 10th school grouping system into the 11th. The result would be expected to ease the gender imbalance and the concentration of private middle schools, to improve the student walking condition to school.
