The 'Integrated Inquiry' unit is a new addition in the 5th~6th grade science textbooks, and was developed for the 2009 revised national curriculum. The unit deals with six integrated inquiry process skills: problem cognition, formulating hypotheses, controlling variables, transforming and interpreting data, drawing results, and generalization. The purpose of this study is to investigate the perceptions and the teaching practices of elementary school teachers on this unit in their school curriculum and where improvements can be made. Data was collected from questionnaires filled out by 92 elementary school teachers. The results are as follows: First, teachers do have a positive perception on the importance of teaching integrated process skills. Second, with that being true, this unit ended up receiving both positive and negative reviews by teachers. This research found that there were good and bad responses on the educational aspects of this unit in three particular areas: dealing with the development of integrated inquiry process skills, facilitating science learning in other units, and implementing open inquiry. Third, teachers have difficulties particularly in problem cognition, formulating hypotheses, controlling variables, transforming and interpreting data, generalization, and drawing results. There is a lack of student understanding as well as a lack of professionalism for teachers on this unit, and many issues related to the composition of the textbook. This study may have important implications for making improvements in this unit and teaching integrated process skills.

Widespread recognition of the various aspects of science education has been prompted by post-positivist philosophers' discussions of the nature of science and intense debates among constructivist psychologists about learning in science. Their discussions and debates, in turn, have raised the problems associated with teaching/learning of science in the schools. The purpose of this article, basically based on the reviews and analyses of the literature related to philosophy of science and psychology, was to describe the implications of post-positivism and constructivism for current science education in the schools. In this paper, the author defines science education as education of/about science, and education through/by science. He also stresses that scientific literacy and decision-making should be emphasized as the goals of science education, that the ethical dimensions of science and technology must be included in science curriculum, that group discussion and/or cooperative learning are effective teaching strategy for science as interpreted by post-positivists and constructivists, and that the assessment should be focused on the degree to which cognitive structure has been changed through instruction in the school classrooms.

In this study, we investigated pre-service secondary chemistry teachers' use of teacher's guide in planning lessons. Eleven pre-service teachers at a college of education in Seoul participated in this study. Textbooks and teacher's guide books including various teaching materials were provided. Pre-service teachers used teacher's guide while they planned two lessons, which were a lecture and an instruction using science teaching model. A semi-structured interview was conducted. All of the teaching-learning materials and interviews were analyzed. The analyses of the results revealed that most pre-service teachers followed each lesson presented in teacher's guide, but they did not consider the structure of the whole unit and science curriculum. There were some cases that the exemplary lesson planning in teacher's guide helped them to select science teaching model. They modified the questions of textbook activity in planning their lecture. On the other hand, they modified the activity to fit each stage of the model in planning their instruction using science teaching models. Most pre-service teachers constructed their own worksheets by applying the materials of the teacher's guide. They recognized the components of assessment by considering exemplary lesson planning from the teacher's guide, and created questions by modifying the content of textbooks and teacher's guide books including various teaching materials. However, the questions which they made were limited in context of knowledge. They evaluated that introductory questions were not of interest to students, and modified or added new materials. Educational implications of these findings are discussed.

This study conducted an online survey to understand what elementary school teachers think about the learning contents of elementary science education subjects needed to train elementary science teachers suitable for the era of the 4th Industrial Revolution. The results are as follows: First, there were many elementary school teachers who thought that the current learning content of elementary science education was not suitable for the era of the 4th Industrial Revolution and that it needed to modify the learning content. Many of the teachers said that the learning content of the subject did not include the characteristics of the 4th Industrial Revolution, but also did not reflect the changes of the times and remained in the past. Second, the content that elementary school teachers thought was important in training elementary school teachers suitable for the era of the 4th Industrial Revolution was mainly related to the interests and curiosity of students, and scientific experiments or inquiry. On the contrary, the items that they thought should be deleted or reduced included science learning theory, science teaching/learning model, nature of science, and guidance for gifted children. Third, the contents that elementary school teachers thought needed to be added as learning content of elementary science education subjects were SSI education, science education-related social change and future prediction, advanced science technology, STEAM guidance, and integrated education within the science field. Fourth, in order to train elementary school teachers suitable for the era of the 4th Industrial Revolution, the contents that they thought should be introduced first as learning content of elementary science education subjects were SSI education, integrated education within the science field, STEAM guidance, and core competencies. Other contents that need to be introduced were software education, safety education, and project learning methods.

The purpose of this study was to investigate beginning earth science teachers' perceptions about Learning in Geologic Field Trip. The hundred and sixteen high school earth science teachers who were in the training for their promotion answered the questionnaire of Learning in Geologic Field Trip. It was divided into five parts: needs and educational values, teachers' experiences and their difficulties, and desirable teaching methods of Learning in Geologic Field Trip. Results indicated that the participants perceived Learning in Geologic Field Trip important in earth science education and responded positively to the educational values of Learning in Geologic Field Trip. Most of the beginning teachers had experience of geologic field trip, but did not learn how to teach it to their students during the geologic field trip in the pre-service training program. It was shown that only a few teachers had experience of geologic field trip and of teaching students in the outdoor of geologic fields after they became a classroom teacher. Most of the participants perceived that teaching students about the geologic field trip is difficult because of lack of their experience. In order to overcome the difficulty, teachers suggested that they need to learn how to teach the geologic field trip to students through their in-service training. leachers suggested that a desirable teaching method of the geologic field trip is to provide teachers with a teacher's manual including geological explanation and information about field trip sites before their visit so that they can scaffold it and facilitate the students' cooperative group activity during the field trip. As a follow up activity, the participants agreed that the presentation and discussion about the results should concur.

In this study, we explored the meaning of science education in an inclusive education setting tram the view of the epistemological approach, and discussed the principles and theories for constructing an educational program. Also, we explored the possibility of inclusive education in science education by suggesting principles for practice: accommodating science curriculum macroscopically, adapting science curriculum microscopically, considering diversity in science instruction, sharing the differences in science teaching and learning, and restructuring the assessment system in science education. We also reviewed the case on learning basic concepts in optics for the visually impaired according to the principles discussed. In conclusion, we discussed the considerations for the practice of inclusive education in science education and inferred further research problems.

The purposes of this study are to investigate Korean science teachers' perception of the current science teacher preparation courses in Korea, especially focused on subjects of science education, and to induce implications for improvement of in-service program for science teachers. To do this, a questionnaire was developed by the authors and administered to the 215 science teachers sampled nationwide. The study concluded that science teachers perceived that the two compulsory subjects, 'science education theories' and 'science teaching-learning materials and teaching methods' were not enough for a professional science teacher. Particularly, they consisently insisted that more practices under the relationship with teaching science in schools were necessary when learning subjects of science education. Based on science teachers' response, we recommended that the following 4 subjects should be added in the course of pre-service program for science teachers: 'Development of experiment/demonstration devices', 'Teaching creativity and education for the gifted in science', 'Development of science teaching materials', and 'Science inquiry learning and teaching'.

In an elementary school science teacher's guide, the guide in details that can help elementary school teachers with difficulties when preparing and conducting science classes are essential. To gain insights into the development of the 2022 revised curriculum elementary school science teacher's guide, it is necessary to investigate the perceptions and needs of elementary school teacher's guide in details. In this study, we developed a questionnaire by analyzing the components and design of an elementary school science teacher's guide in details to explore elementary school teachers' perceptions and needs. For this purpose, we first investigated elementary school teachers' perceptions of their needs, satisfaction, and the utilization of each component of the current guide in details. Next, we investigated teachers' needs regarding the specific components and design of a guide. The findings were as follows. First, elementary school teachers were delighted with the components that help them prepare and conduct lessons. Second, elementary school teachers wanted an easy-to-read design with a layout that allowed them to see the components they needed for their lessons at a glance. In conclusion, the elementary school science teacher's guide in details to be readable and organized to provide at-a-glance information on lesson preparation, lesson flow, and teaching and learning materials needed for science teaching-learning. Based on the results of this study, new approaches and attempts should be made to develop a textbook that elementary school teachers can utilize in the future.
