The purpose of this study was to investigate the elementary school teachers' perceptions about the science subject exclusive system. For this study, we developed the questionnaire to investigate teachers' perceptions and 43 elementary school teachers participated in the questionnaire test. And we used participation observation method to investigate characteristics the exclusive elementary science teacher and the elementary school homeroom teacher's science classes. After participation observation, we had interviews with exclusive elementary school science teacher and elementary school homeroom teacher. The results showed that elementary school teachers thought the science subject exclusive system was very necessary. And elementary school teachers thought that the exclusive elementary science teacher had higher professionality about teaching science subject than the homeroom teacher. Then, they expected that the strong points of science subject exclusive system would be some solution to the weak points of homeroom teachers' science classes. We suggested that it must be to enlarge the science subject exclusive system and develope in-service teacher program for the exclusive elementary science teachers.

The purpose of this study was to examine whether the new introduction of elementary science experiment specialist is appropriate under the current situation of serious emphasis of the importance in science experiments in elementary science in Korea. For this study, the survey items were developed twice through the preliminary study. The results show that most elementary teachers consider the importance of experiment in elementary science and the critical role of science experiments to increase students' curiosity and scientific understanding. About 80% of the teachers stressed the professionalism in elementary science. Although 65% of the teachers believed their having basic professionalism, 53% of them appealed the difficulty in teaching science experiments to students. Nevertheless, 67.5% of the teachers opposed to the idea of teaching elementary science in separation between experiment and theory in science, and only 8% of them agreed the idea of induction or adoption of the college graduates majoring in science and engineering, or holding the secondary teacher's certificate. Further, over 60% of the teachers responded no necessity of inducing the new policy of elementary science specialist. Many numbers of teachers revealed their serious worries about the new policy because of their past experience to suffer from the side effects of inducing the teachers with secondary teacher certificate to the elementary school. In particular, they also made a proposal to make a good use of the current system of exclusive elementary science teacher in Korea. The educational implication and suggestions for policy making were discussed.

The purpose of this study was to analyze the stresses of teachers for elementary science class. To do these, the Science Teacher Stress Inventory has been developed the Science Teacher Stress Inventory, which consisted of 45 stress factors with subcategories such as student characteristics, teacher characteristics, expertise of science education, school environment, and administrative procedures. 120 teachers for elementary science class have participated in this questionnaire survey. The results of this study are as follow: First, stress from teacher characteristics is perceived as having more stress factors than five stress factors (student characteristics, teacher characteristics, expertise of science education, school environment, and administrative procedures). but all of the five stress factors was under normal. The detail question of stress such as 'Having to guide educational guidance and course in life education', 'Having to cope with the demand of new curricula', 'Pace of the school day is too fast', 'No time to attend training of the experiment (preliminary experiment)', 'Not enough time to complete lesson preparation and marking', 'Having to cope with non-teaching delegated duties', 'Fear of getting injured as a result of lab accidents' are perceived as having a lot of stresses. Second, there were not statistically significant differences in their personal variables such as gender, the course of high school. but there were statistically significant differences in their personal variables such as whether elementary subject exclusive science teacher, career in education experience, teaching grade. Third, coping ways of stresses are active support for better science teaching conditions, training of the experiment for expertise of science education, developing a workbook for science class.

The purpose of this study is to analyze the elementary teachers' professional performance about science teaching practice according to their personal variables. For this study, professional performance test was modified based on Woo's 'framework for progression and learning in the professional development of elementary teachers' science teaching practice', which included 6 elements such as 'lesson plans', 'creating the learning environment', 'inquiry', 'conceptual understanding', 'practical application', and 'assessment'. And then it conducted to 79 elementary teachers. The collected data were analyzed by the statistical package SPSS. The results of this study were as follows: There was statistically significant difference in the sub-domains of professional performance according to teachers' career, experience of training program, deciding method of exclusive subject. But there was almost no significant difference in other personal variables, such as gender, major, etc. Findings suggest that there are needs of further study about interaction effects of personal variables affecting teachers' professional performance of science teaching practice in detail.

The purpose of this study is to analyze the problems of land and sea breeze model experiment that has presented in $5^{th}$ grade curriculum in chapter "Weather and our lives" and makes better model simulation so that learners can have better and more effective way to study it. To survey the opinions from dedicated teachers about land and sea breeze model experiment, we produced the survey through interview with science exclusive teacher from M elementary school. An elementary science education expert, 3 men of science EdD modified and complemented survey and started Delphi survey to 12 science teachers who have career teaching more than 3 years. The problems found in this survey were 'one heat bulb, short heating time, small temperature difference of water and sand, lack of class time, empty space between sand and water, back of transparent boxes, little amount of scent and the location of the it' etc. But the most of all, it is hard to see the successful result of the experiment. Based on these kinds of investigations, and lots of trial and error, redesigned the new model experiment that has the most similarity to the real one and high probability of success. According to this, it was able to see the smoke forms horizontal movement along the sand and the smoke goes in one circulation cycle. through this experiment, we made a conclusion that although those scientific experiments in textbook were developed through lots of considerations of expert, to consider the aspect of consumer, it needs to reach the educational agreement about simulation experiment so that It can lead to successful experiment and high quality education.

연구의 목적은 PBL 수업과 관련된 사례 연구들을 조사 분석하여 도출된 기초자료를 근거로 PBL 수업과 연계하여 학교도서관의 도서관협력수업을 활성화시키는 방안을 제시하는 것이다. PBL 수업이 국내 초 중등교육 현장에 도입되어 사례연구가 본격적으로 시작된 2000년대부터 2018년 현재까지 수행된 국내 PBL 관련 사례연구들을 조사대상으로 하여 초 중 고등학교로 구분하여 대상학년, 교과목, 수업형태, 학습문제 해결을 위한 정보원 종류, 협력수업 여부, 도서관협력수업 여부, 교육적 효과에 중점을 두고 조사 분석하였다. 분석 결과, PBL 사례연구가 가장 많이 실시된 학교급은 초등학교, 중학교, 고등학교 순으로 많았으며 수업형태는 협력수업보다는 단독수업진행이 대부분이었다. PBL을 적용한 교과목계열은 자연과학, 인문사회, 예체능계열 순으로 많았으며 도서관과 협력하여 실행된 PBL수업은 저조하였다. PBL수업의 주된 교육적 효과로는 학업성취도, 만족도, 창의력, 문제해결능력, 자기 주도적 학습능력 신장으로 나타났다. 이를 기초로 학교현장에서 도서관협력수업을 활성화시키기 위해서는 사서교사들의 적극적인 인식전환 뿐만 아니라 PBL수업에 집중하여 교과교사와 수업지도안 설계단계부터 평가에 이르기까지 협력하여 적용할 것을 제안하였다.
