The purpose of this study was to investigate the difficulties of science classes experienced by newly appointed elementary school teachers in terms of science content knowledge and teaching method, and to suggest some implications for their effective adaptation. We recorded science lessons conducted by 3 beginning elementary school teachers with less than 5 years experience and also analyzed their classes and interview materials. The results were as follows. First, difficulties that they experienced in science content knowledge was the possession of scientific errors or misconceptions, the lack of awareness and confidence in scientific concepts and principles, and the possession of negative concept about learning materials. Second, difficulties that they experienced in teaching method was the absence of reorganization of the textbook contents, using closed questions, one-sided instructions and explanations by teacher, the application of incomplete analogy, and the lack of understanding about experiment activities. The implication from this study is that beginning teachers need to be provided with curriculum oriented in experiment at teachers college and to participate in various types of educational opportunities.

We examined how the professors in the department of science education perceived the 6th high school science curriculum. A nationwide survey was administered to obtain the responses from 70 professors of 8 educational colleges. Most professors thought that the 'objectives' and the 'contents' were proper, but the 'methods' and 'evaluations' were not proper, if considered educational facilities as well as 'teachers' ability to guide inquiry. Some professors also pointed out that the 'methods' described in the curriculum did not seem to be practical, that the contents were too much for high school science courses, that the integration of the contents in the general science was not enough, and that some concrete guides were needed because the items in the curriculum were too broad.

The purpose of this study was to develop a brain-based analysis framework for evaluating teachinglearning program in science. To develop the framework, this study categorized educational constructs of the teachinglearning programs into one of three teaching-learning factors: cognition, motive, and emotion, using previous studies on science program. Ninety-three articles on the brain functions associated with science program were analyzed to extract brain activation regions related to the three educational constructs. After delineating the brain activation regions, we designed the brain function map, "the CORE Brain Map." Based on this brain map, we developed a brain-based analysis framework for evaluating science teaching-learning program using R & D processes. This framework consists of the brain regions, the bilateral dorsolateral prefrontal cortex, the bilateral ventrolateral prefrontal cortex, the bilateral orbitofrontal cortex, the anterior cingulate gyrus, the bilateral parietal cortex, the bilateral temporal cortex, the bilateral occipital cortex, the bilateral hippocampus, the bilateral amygdala, the bilateral nucleus accumbens, the bilateral striatum and the midbrain regions. These brain regions are associated with the aforementioned three educational factors; cognition, motivation, and emotion. The framework could be applied to the analysis and diagnosis of various teaching and learning programs in science.

Despite the growing importance of socio-scientific issues (SSI), little work has focused on teachers' pedagogical knowledge, and few studies have examined how in-service teachers use and apply SSI-related instructional methods and strategies. Consequently, the purpose of this study was to explore how science teachers with lots of SSI teaching experience determined teaching orientation, selected and revised instructional methods, and devised assessments in science classroom. We used a case study approach aimed at a deep description of these teachers' teaching experiences and employed semi-structured and in-depth interviews with five experienced teachers. Our findings indicate that teaching orientation and learning objectives seemed to influence the selection and modification of instructional strategies and methods. In addition, students' learning experiences or classroom environment were considered and modified in light of achieving these learning objectives. However, introducing SSI into the classroom assessment is not seriously considered by most teachers. This study can provide teachers with useful information when designing and developing SSI classes, taking into account various aspects of the PCK such as learning orientation, instructional methods, learner expereince and curriculum standards.

최근 컴퓨터 교육의 초점은 컴퓨터 내용학으로 소양 교육에 대한 관심이 고조되면서 컴퓨터 과학 요소 및 정보통신윤리 분야를 강화하며 소양 교육과 교과 활용교육 간의 연계를 통하여 효과적으로 교육 목표를 달성할 수 있도록 하였다. 이에 따라 일선 학교에서 컴퓨터, 컴퓨터 통신, 멀티미디어, 인터넷 등의 첨단 정보 매체를 교수 학습에 어떻게 활용할 것인가에 대한 관심을 넘어 정보 교육 본질적인 관점에서 교육 방법을 찾고자 노력이 고조 되고 있다. 본 연구에서는 초등학생들에게 지도하기 어렵고 학생들이 이해하기 힘든 컴퓨터과학에 기본이 되는 컴퓨터 내용학 중 자료구조의 검색과 정렬 중 정렬 알고리즘에 대해 교수 학습방법을 설계해 이를 지도해 보고 이러한 학습내용이 초등학교 학생들에게 효과적으로 학습되는 모형을 적용하여 실효성과 이해를 높일수 있으리라 기대한다.

As a theoretical background for this research, the literatures which focus on teaching and loaming of connecting with mathematics and science were investigated. And the rationale of integrated curriculum on the basis of the 7th mathematics curriculum and the goal of mathematics education and the forms of integrated curriculum and the integrated curriculum in foreign school were investigated. Depending on this review, the implement method of the integrated curriculum of mathematics and science in Korea school is suggested as the following: It requires designing inter-disciplinary into-grated problem or various teaching and learning materials which are based upon concept, skill, and principle by commonality found across the subject matter. Based on the analyses upon described above, three inter-disciplinary integrated teaching and learning materials were developed. And then, based on the case stud)', the research questions were analyzed in depth. Students could understand the developing process of linear function, develop the formula and grape representing the relationship between time and velocity, time and distance, and interpret realistic meaning of the slope.

We have studied possibilities of Peer Instruction(PI) to train in-service science teachers in elementary and middle schools through both degree of conceptual changes and investigating responses to questionaries. 169 teachers were attended and the subject for training was about light propagation to teach scientific conception about a pin hole camera. 6 conceptests were developed. Degree of conceptual changes was analyzed from results obtained from 24 elementary and 32 middle school teachers among them. On the other hand, answers to questionaries were obtained from 135. Relatively high gain near to about 0.7 in conceptual changes was obtained even though their initial levels were quite low. Interesting point is that elementary teachers have higher initial level and larger gain than middle school teachers. Teachers have very much enjoyed and showed strong support to PI for helping conceptual change, and willing to use PI to their own class. Also they conceived dealing concept in teacher training is very important and evaluated PI very positively for teacher training.

The purposes of this study is to identify the professional knowledge of the three elementary teachers for science-gifted students in teaching method. All teachers have received in-service program in gifted education, and have been recommended by their colleagues. Two teachers have instructed the gifted for more than five years, one teacher have instructed the gifted for one year and the general students for eleven years. For for this study, each teacher's lesson plans were collected, videotapes were recorded during lessons, and in-depth interview for each participant were conducted. All recoded data were transcribed and analyzed. Some unique characteristics of teaching method for the gifted were identified from the class instruction of participants. They had knowledge of teaching model for the gifted, especially Renzulli's three pod enrichment model. And they mainly used the materials developed by KEDI for the gifted. Also they had capability to be able to reconstruct them, but their lesson plans did not be realized well in their class. Some implications from findings of this study were suggested, such as teaching methods to improve the quality in the classes of the gifted in science.
