The purpose of this study was to survey science teachers, perception and attitudes on disposal of school laboratory waste water and materials. To fulfill this aim, a questionnaire was administered to 244 secondary school science teachers. The result of this study revealed that there was no large disparity in the degree of understanding of laboratory waste disposal and the laboratory waste water treatment, and in secondary science teachers' perception and practicing attitude on the environment. While science teachers had deep understanding of laboratory waste disposal and its influence on environmental pollution, they expressed less positive attitude toward the actual disposal of waste materials and waste water, and participation in teacher training. Therefore, it is necessary to provide standards of systematized disposal methods and proper disposal facilities in middle and high school laboratories, as well as to investigate teachers' needs before providing teacher training program.

This study investigated Korean science teachers' concerns and needs regarding inquiry testing to cope with the innovation called College Scholastic Abilities Test(CSAT), which was officially first administered as the nation-wide college entrance exam in 1994. This study adopted Concerns Based Adoption Model(CBAM) as the theoretical framework developed by Hall et al. 60 high science teachers (30 physics, 20 earth science, 10 others) were involved for the main study in August, 1992. In general. science teachers demonstrated a concern profile similar to that of 'nonusers'. They showed high level of concerns on the 'information' and 'personal' stage, while low level of concerns on 'management' and 'consequence' stage. Science teachers expressed their strong needs for knowledge and support to facilitate inquiry teaching and testing, text books written in inquiry mode. It is recommended that in-service trainings be provided based on the concerns and needs of teachers for a better teacher training and successful implementation of the innovation.

본 연구에서는 교육대학원에서 초등과학교육을 전공하고 있는 28명의 교사들을 참여자로 하여 그들의 생활 세계 속에서 형성된 과학 수업의 의미를 현상학적인 관점에서 탐색해 보았다. 그 결과, 초등 교사들에게 과학 수업의 의미는 일양(一樣)하게 나타나는 것이 아니라 교사들이 경험하는 상황에 따라 조금씩 달라진다는 것을 알 수 있었다. 즉, 열정이 넘치는 초임교사 시절에 과학은 그 즐거움을 학생들과 나누고 싶은 교과이다. 그래서 교사들은 과학 수업뿐만 아니라 과학과 관련된 학교 일을 도맡아 할 정도로 의욕을 보인다. 하지만 점차로 좋은 과학 수업을 고민하게 되고실험과 초등학교 학생들의 특성을 깨닫게 되면서 고민은 더욱 깊어진다. 과학 수업을 둘러싼 초등 교사들의 이러한 고민이 실제로 좋은 과학 수업으로 승화되어 나타나기에는 학교의 과중한 업무, 실험실 사고, 가정을 돌봐야 하는 부담이 장애 요인으로 작용한다. 이러한 어려움 속에서도 교사들은 더 좋은 과학 수업을 위한 고민과 노력을 다시 시작하지만, 그러한 노력에도 불구하고 과학 수업은 여전히 잘 되지 않는 부분이 있기 때문에 초등학교 교사들에게는 "채워지지 않는 잔(盞)"처럼 남아 있다.

In their teaching practice, teachers encounter multi-dimensions of pedagogical challenges. The recognition and reflection on these challenges is crucial to advance our science teaching. This study looked into science teachers' dilemmas of their teaching practical work through their written cases. Dilemma cases are teachers' narratives organized around important events of teaching and learning. It can reveal teachers' situated cognition and be used as lens to investigate complex realities of science teaching and learning. 26 pre- and in-service elementary teachers' dilemma cases of science practical work were carefully collected and analysed to interpret what constitute tensions in elementary science practical works. They were largely grouped into three: Curriculum and Institutional Relevance, Students Relevance, Nature of School Experiments Relevance and divided into 7 subheadings: 'Authority of Curriculum(textbook)', 'Disappointment at external support', 'Students' interests and safety', 'Students' unscientific and inert attitude', 'Difficulty of showing expected results', 'Generalization through experiment', 'Knowledge acquisition and authentic inquiry'. Each dilemma was interpreted in terms of the tensions which constitute contradictory beliefs, values, expectation and realities. These dilemmas enabled to expose actual conditions of elementary science practical work and teachers' challenges otherwise can not be seen easily. Science teacher educators also can get some implications to overcome the gap between theory and practice in their teacher education.

The purpose of this study was to investigate the characteristics of lesson planning of pre-service elementary teachers to develop scientific communication skills for elementary school students. For this purpose, lesson plans and lesson planning journals written by the 53 pre-service teachers were collected and analyzed. The results of the research were as follows. The pre-service elementary teachers used an implicit and contextual approach to develop scientific communication skills. Teaching and learning activities for enhancing scientific communication were mainly conducted in words or in writing. There were many activities expressing elementary school students' thoughts and presenting the results of experiments in the lesson plan. There were many cases in which the pre-service teachers' lesson plans did not include the evaluation of scientific communication skills. In their lesson plans, there are a lot of mutual activities between teachers and students, team and whole students, and inter-students within teams together, and students' individual activities from requests of teachers. We found that the pre-service teachers had various difficulties when they planned the science lesson to develop scientific communication skills. The pre-service teachers were less likely to refer to specialized materials related to science education when planning their classes.

Developing pedagogical content knowledge (PCK) has been emphasized for teacher's professionalism and it should be done from systematic teacher training courses. In this study, we investigated changes of elementary pre-service teachers' PCK of science teaching and motivational strategies before and after a training course. For the analysis of pre-service teachers' PCK, their lesson plans, surveys, and interviews were collected. According to the results, in the beginning of the semester, pre-service teachers in the experimental group usually used didactic or combination of didactic and inquiry teaching strategies and a few pre-service teachers used inquiry or discovery teaching strategies when making lesson plans. However, at the end of the semester many pre-service teachers used inquiry teaching strategies in their lessons which included activities of asking students' prior knowledge, conducing experiments, finding conclusion, and comparing teachers' explanations with students' explanations. Regarding motivational strategies, in the beginning of the semester they focused using activities to create student's emotional interest in science lesson but at the end they used other strategies to create positive atmosphere for learning, capture intellectual interest in science, and connect science to students' everyday lives. The changes in pre-service teachers' PCK in the experimental group was meaningful because there was less change in pre-service teachers' PCK in the control group. This study implies the need for effective professional development programs for developing pre-service teachers' PCK.

This study investigates the implementation of the Converged Science, and what teachers and students think of it in order to understand how it is taking root in schools. The results identify ways in which the new curriculum can establish itself in schools. One hundred and two science teachers, who had participated in the mandatory workshop for the 2009 Amended Course of Science, were given the first survey regarding their general perception of the converged science curriculum. A year after the first implementation of the new curriculum, one hundred and seventy one science teachers were given the second survey in order to determine their general perception and actual results in the classrooms. A similar survey was given to one hundred and forty nine tenth grade students. In addition, one hundred and forty eight tenth grade students, who had experienced the new science curriculum, took part in another survey revealing their general thoughts the course. The results show that the teachers' responses are rarely positive. The teachers claimed that the contents were too extensive while the level of fundamental concepts were too rigorous for tenth graders. They also asserted that the contents contained too much of a particular subject, and that it is necessary to lower the level of rigor. With regard to the level of unification of converged science textbooks, the teachers expressed that they are still slightly inadequate. The subject of science in the seventh curricula was criticized due to its lack of convergence: over 90% of the respondents answered negatively. On the other hand, the students responded more positively: they said that the new converged science was difficult to learn, but was interesting. In Busan, most high schools adopted the new curriculum in the first year when it was introduced for the first time. In most cases (over 80%), several teachers divided and taught the contents either according to their majors or regardless of their majors.

The enhancement of the quality of the teaching practice is a major factor in securing better schooling opportunities for students. In this article, initial teacher preparation of secondary school Earth science teachers, in-service science teacher education, and improving teacher policy are discussed. Data from in-depth interviews with exemplary science teachers were used to explore how to improve the quality of science teacher education in Korea. In terms of preservice teacher education, most exemplary teachers contended that teacher education programs should provide preservice teachers with practical knowledge by translating theory into practice. Their suggestions for how to improve in-service education are also discussed. Regarding directions of improving teacher policy in Korea, the teachers proposed an alternative teacher-promotion structure that incorporates the master-teacher position. Implications for introducing action research courses into teacher (re)education programs are also discussed.
