The purpose of this study was to compare the illustrations used in elementary science textbooks of Korea and BSCS in USA, and analyze the types, role, and characteristics of the illustrations. For the analysis, we used 8 elementary science textbooks of the 7th curriculum of science education in Korea from 3rd through 6th grade, and 16 volumes (stage 2 to stage 5) used in BSCS in USA. We examined types of illustrations, including photograph, picture, graphic, cartoon, chart, and their 4 roles such as, motivation, introducing the lesson activity, providing the materials, presenting the learning result. The results were as follows: First, Korean textbooks have more "photograph" type of illustration than BSCS. In BSCS textbooks, diverse types of illustrations were used compared to Korean textbooks. Second, large portion of illustrations in Korean textbooks took a role of providing materials. In BSCS textbooks, the roles of illustrations were more diverse. In BSCS, there were many illustrations to describe students working together with the disabled children, and to explicitly encourage cooperative learning. Considering the findings in this study, educational implications were discussed.

The purposes of this study were as follows; to investigate elementary school teachers' understanding of scientific inquiry, experiences in learning/teaching, their educational experience of scientific inquiry, and to study the difficulties they experience in teaching scientific inquiry methods to elementary students and their suggestions for future inquiry materials. For the purposes of this study, 157 elementary school teachers participated in a survey and 10 teachers were interviewed in-depth in relation to their ideas and experiences of scientific inquiry. The results show that most elementary school teachers had a lack of understanding of scientific inquiry skills, and lacked educational experiences of inquiry methods in general. They generally perceived the 7th science text-books as being inappropriate and inadequate for teaching students scientific inquiry processes. The educational implications are discussed to help practitioners implement scientific inquiries successfully through the various types of teaching materials and professional developments.

The purpose of this study was to investigate the effect of the experience-based ecology-environmental STEAM education on ecological sensitivity of elementary students. The research subjects were 62 third graders of S elementary school located in Incheon. They were divided into the experimental group of 33 students and the comparative group of 29 students. The experimental group was provided the educational program with the experience-based ecology-environmental STEAM education. The comparative group was provided the theoretical and ecological self activity program based on the textbook. The results of this study can be summarized as follows; First, the experience-based ecology-environmental STEAM education had a meaningful effect on improvement of ecological sensitivity. Second, we found that access to the ecological environment education is important in all subjects, not in education that is biased toward. Third, in ecological environment education, experience-oriented education methods are more meaningful than indirect experiences trapped in textbooks. Fourth, ecological environment education can contribute to the improvement of ecological sensitivity as well as the intellectual aspect of ecology and environmental science. In conclusion, it was found that the ecological environment program should be conducted with activities of experience.

The purpose of this study was to examine the status and science teachers' perceptions of classes for those gifted in science in elementary school. For this purpose, a number of questions were posed to teachers : 27-item-questionnaires were given to 38 teachers of students gifted in science in elementary schools located in Incheon province. The results of this study were as follows : 1. most elementary teachers were in charge of classes containing students gifted in science, but this was the case with only a few secondary teachers. Therefore, it appears to be more necessary to educate elementary teachers who majored in science content and gifted education. 2. In addition, most teachers had positive perceptions of the needs, attitudes and environments needed for gifted education. Most of them attended 60-hour training programs on gifted education. They thought that it was helpful in understanding the characteristics of gifted students, but they wanted to learn more about actual pedagogical methods through such programs. 3. The teaching methods used in classes for those gifted in science were mainly experimental activities, but there were few opportunities for creative problem solving and project learning. This may be due to limited class time of about one hour every two weeks in this class. 4. When the materials used in class were first developed, they mainly used materials made by the city board of education and selected the theme of interest by themselves. Therefore, there may be problems of duplication of materials or systems regarding the science contents for one year. 5. Furthermore, the themes of the materials used were mostly related in terms of the contents of textbooks than more generally. When planning and managing the classes for those gifted in science, the above points should be considered in order to improve the education of those students gifted in science.

This study investigated how elementary school teachers reconstruct science curriculum and how they perceive about their experiences. In-depth interviews were conducted with four elementary school teachers who had experience in restructuring science curriculum. Two distinct types of reconstruction were found; restructuring within the subject and integrating between subjects. The teachers who were restructuring science curriculum from personal needs usually substitute, delete, add some contents or activities and change the order of unit within science subject. In contrast, the teachers who were participating in research school usually integrated science with other subjects, developing a new unit or project. The latter recognized the need of teachers' reconstruction of science curriculum more strongly and the importance of teacher's voluntary learning community in implementing the reconstruction. Though they had some difficulties in identifying students' interests and level of understanding and lack of time, all teachers valued curriculum reconstruction by relating it to teacher professional development, identity as a teacher, and job consciousness.

The purpose of this study was to confirm achievement of goals in science curriculum. The questionnaires related to 'solution' chapter of 5th grade were developed. The subjects were 69 sixth grade elementary school students and four elementary school teachers. 5 students were selected for deep interviews. Each interview was progressed separately, and all the contents of the interviews were recorded. As results, it is revealed that most of the students could not understand basic concepts of 'solution' chapter. The teachers and the students recognized that explanations in the textbook were insufficient. Many inquiry activities were introduced in textbooks, but the students could not acquire inquiry abilities, especially data interpretation and generalization abilities. Inadequate pictures in the textbook also disturbed the students' learning of inquiry ability. Using materials of real life in textbook could not attract the elementary school students' interests effectively.

While most previous studies have developed educational programs for science gifted children and have analyzed the differences between science gifted children and ordinary children using quantitative research methods, few have investigated the differences among the science gifted, especially in terms of the scientific thinking process. The present study was conducted to explore the thinking characteristics of the elementary science gifted according to the three scientific thinking process types during the scientific problem solving process. The study resulted in the collected of quantitative and qualitative data through tests and an interview with questions and scientific problems which required the use of one of the three scientific thinking processes. Ten elementary science gifted children served as interviewees. Two types as an opistemological basis for solving the problems are revealed on inductive thinking problems. Three types are on abductive thinking, and Three or Four types are on deductive. The results are expected to have an influence on the teaching and the evaluation of the elementary science gifted.
