The purpose of this study was to investigate teachers' perception about 'Science Field Trip(SFT) to Korean historical sites'. Ninety-seven teachers were asked to reply the questionnaire about SFT to Korean historical sites. This questionnaire was divided into three parts: educational value, teaching method, and difficulty of management. Firstly, teachers indicated that SFT to Korean historical sites had much educational value in that it could give students chances to understand Korean culture, to acquire investigative process skills, to experience divergent investigation and cooperative learning, to raise integrated thinking skill concerning science and other subjects, and to learn contents related with science curriculum. It also had advantages of caring for students out of school and giving the information for future occupation. Secondly, teachers suggested the desirable teaching method: teachers' explanation about SFT to Korean historical sites with worksheets before it, students' group work during it, and the presentation and discussion after it. Finally, the most frequent answer in the difficulty of management was the lack of teaching materialsfor SFT to Korean historical sites.

Educational efforts in integrating various subjects which are closely related to one another have had positive results. Additionally, integrating subjects has shown to be more effective than teaching subjects independently. The purpose of this study is to propose, construct, and develop a theme-based integrated program that teaches elementary school student's subjects which are outside the regular curriculum such as electricity, electronics, programming, and energy by using Diki-3000. Thus, having considered the theoretical background of theme-based integrated program, elementary school subjects including home economics, science, social studies, and extracurricular activities have been analyzed and restructured into theme-based program. Students will learn about and familiarize themselves with these subjects by utilizing the Diki-3000 product. This program aims to improve students understanding of the aforementioned subjects by combining Diki-3000's strengths as an educational tool with the contents of theme-based integrated program. Moreover, the learning experiences gained from completing critical problem-solving activities which are beyond normal subject knowledge is expected to help develop learners' positive thinking skills.

In this research, we have developed a "computer tutor" that mimics the human tutor with animated tutoring dialog agent and the agent was integrated to teaching-learning material for elementary science subject. The developed system is a natural language based teaching-learning system using one-to-one dialogue. The developed pedagogical dialogue teaching-learning system analysis student's answer then provides appropriate answer or questions after comparing the student's answer with elementary school level achievement. When the agent gives either question or answer it uses the TTS(Text-to-Speech) function. Also the agent has an animated human tutor face for providing more human like feedback. The developed dialogue interface has been applied to 64 6th grade students. The test results show that the test group's average score is higher than the control group by 10.797. This shows that unlike conventional web courseware, our approach that "ask-answer" process and the animated character, which has human tutor's emotional expression, attracts students and helps to immerse to the courseware.

During the last two decades, many researchers have attempted to understand pedagogical content knowledge (PCK). Now it is time to think about how to apply the theoretical aspects of PCK to practice. In an attempt to address this issue, it is indispensable to review the existing literature on teachers' knowledge bases and PCK. Therefore, the purposes of this paper are to look at how the concept of PCK has been developed and extended over the past two decades as well as to provide a shared understanding of PCK for the practical use of this concept in teacher education programs. The paper begins with a discussion of various models of teachers' knowledge as conceptualized by several renowned researchers, moves on to a review of existing research focusing on the knowledge of science teachers, then examines the literature on PCK as a critical part of teachers' professional knowledge, and finally concludes with an integrated operational definition of PCK that can be employed into designing teacher education programs.

This study is to implicate for analyzing the expertise of Education for Sustainable Development (ESD) dealing with science-related social issues by reorganizing educational materials on climate crisis topics and analyzing in-depth class performance preparation and actual class by pre-service science teachers. As a result of the study, it was found that pre-service science teachers have the expertise to analyze the curriculum horizontally and extract subject-integrated elements, but it is difficult to perform convergent science classes by incorporating them into the social problem-solving process in actual classes. In addition, it was analyzed that through this study, pre-service science teachers came to think about the importance of having their own specialized expertise when they become school teachers through preparation for their classes integrating science-related social issues. Through the application of the reciprocal peer teaching applied in this study, giving pre-service science teachers of various expertise an opportunity to experience the process of designing and implementing integrated science classes while sharing their expertise will greatly help them improve their convergence education.

In this study, the contexts and values of the movement called 'Science and Citizenship' during the 1930-50s are discussed in relation to the historical development of school science education in Britain and to the current STS movement in school science. A special attention is given to the activities and ideas of a then eminent biologist, Lancelot Hogben(1895-1975) who published a textbook-like science book, called "Science for the Citizen"(1938). From the beginning of the 20th century, there was a growing realization that British education system needed to be changed in order to provide school science teaching to a wider audience with more emphasis on the relevance, industrial and humanistic aspects of science. This was echoed by a lecture series called 'Science and Citizenship' which was reported in the School Science Review, then the only nationwide professional journal for science educators and by a group of professional scientists who had socialist ideas toward society. Hogben was one of the key member of the group and delivered the second lecture of 'Science and Citizenship', titled "Biological Instruction and education for Citizenship". Hogben's main idea, illustrated in this lecture as well as in "Science for the Citizen", was that science education should be a way of teaching citizen for promoting democratic society and to achieve that science need to be taught in more integrated, utilitarian and humanistic manners, for example by showing the usefulness, relevance, historical and democratic aspects of science. In addition, a summary of his own life and activities, the social background and socialist scientists of the time, and comparisons between 'Science and Citizenship' movement and the General Science movement in the UK as well as the progressive science education in the USA, and the STS education movement in 1980s are discussed.

The purpose of this study was to develop a teaching strategy focused on science writing and to investigate its effects on enhancing students' problem solving ability. A teaching strategy using science writing enhancing problem solving ability (REWS model) was designed. The REWE model consisted of four stages: 1) Sensing and Stating of Scientific Problem by Reading (R stage), 2) Exploring Problem (E stage) 3) Explaining by Writing (W stage), 4) Integrated problem-solving (S stage). 135 10th grade of students were assigned to one experimental group and one control group. Students in the experiment group were taught by REWE model. Students in control group were taught by traditional lecture-based instructions. The program was implemented over a semester. The results indicated that the experimental group presented statistically meaningful improvement in critical thinking necessary to solve problems (p<.05). This study suggests that science writing can be effective for improvement of problem solving ability.

According to the new multi-media appeared as a result of rapid growth of the information and science technique, the school library must be changed to the integration of the teach-study media resource from the existing print media. It means that the school library has to play a role of the study center with a different media from the existing teaching material, teaching instrument, facility and opportunity. The Information education must be conducted in the way of an integrated education course and able to do both information transaction and problem settlement. The education facility to solve this problem is the school library. Therefore, the school library becomes important more and more. It means that the school library is the center of entire study and education material for the teacher and student is focused on it. It is urgent to make the standard of the school library In order to cope with the new education and information environments. And especially it is very important to make a plan about the location and scale of the school library to improve the quality of the children's studying activity. The location of the school library is decided under consideration of the relationship with other room of school house and the proper scale of it is between 2.5units and 7.0units of classroom based on the number of class.
