  • The purpose of this study is to develop a science field study area using Geumgang(Geum River), fossil origins and various geological resources in Youngdong area of Chungcheongbuk-do as educational resources; and utilize them to develop an education program to cultivate earth science and topophilia. The Youngdong sedimentary basin (Cretaceous period) has a well-developed outcrop along the Geumgang and it is therefore easy to find various geological structures, plant fossils, and dinosaur fossils. Also, it has a distinct sedimentary structure, such as mud cracks, ripple marks and cross-bedding. Science field study area(6 observation sites) were developed based on school curriculum, textbook analysis, and professional earth science education panel discussion to create a convergence education program. The result of validating the developed program showed that all the items were satisfactory ($CVR{\geq}0.88$) in the test categories. The science field study teaching-learning model was applied to actual classes. The evaluation result for class satisfaction was positive, scoring Rickert scale 4.18. The result of observation about the outdoor classroom process in the science field study area revealed that students were able to form a new image of the beautiful scenery of the Geumgang. Also, the students could gain a new understanding, concept and value of various geological objects (sandy beach, stepping-stones, dinosaur footprint fossils, sedimentary formation), which naturally allowed them to form topophilia.

  • The purpose of this study is to analyze carbon cycle concepts based on earth systems from the perspective of high school students. The subjects for this study were seven students who have completed Earth-science I curriculum. to analyze of carbon cycle concepts based on earth systems perspective, the methods of word association, casual map and drawing were used. The results of this study were as follows: first, 5 out of 7 students have suggested carbon cycle concepts less than three. Second, the carbon cycle concepts on the change of state were 2. Also, the carbon cycle concets on process were 8. Third, 2 out of 7 students present 2 feedback loops, 3 out of 7 students 1 feedback loops, but 2 out of 7 students couldn't present the feedback loops associated with carbon cycle. Finally, As for carbon cycle concepts through drawing, 1 out of 7 students drew 9 concepts, 3 out of 9 students drew 7 concepts and the rest of them drew 5, 4, 3 concepts respectively. These results suggest that concept and feedback loop thinking skills on carbon cycle are a low level. Therefore, It is suggested that more educational programs be developed on various topics in order for high school students to improve their system thinking skills as well as knowledge integration of earth systems.

  • 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.

  • The purpose of this study is to investigate pre-service middle school earth science teachers' perceptions about the learning of geological field trip. The study sample consists of 39 undergraduate students at the university located in a metropolitan city. Additionally, 4 pre-service earth science teachers are semi-structure interviewed. The instrument of the study includes a 5-category perception about the learning of geological field trip, which consists of needs, educational values, educational experience, teaching methods, and training for learning. The results are as follows. First, participants are important to the need and educational values of learning about the geological field trip regardless of gender and grade level. Second, all participants have experienced geological field trip in college. They have more opportunities to experiment for field trip as they advance to higher grade. There is significant difference between lower and higher graders in terms of the goal of learning about geological field trip. It needs a new lesson model to teach geology between men and women regarding teaching methods category. In order to practice geological field trip in school, participants perceive that they need the knowledge of geological context, experiment of field trips, and how to teach geological field trip to students. This study suggests that pre-service earth science teachers' perceptions include how to teach and learn geological field trip during their college year.

  • This study is to investigate the effect of pre-primary teachers' gender and earth science completion while attending high school on the diversity of concepts, the level of conceptual understanding, and misconceptions about seasonal changes. This study was conducted with 71 pre-primary teachers. The conclusion of this study is as follows. First, the area of concepts used by pre-primary teachers to explain seasonal changes showed a greater difference depending on whether or not they completed earth science while attending high school, rather than depending on gender. Second, although there was no significant gender difference in the conceptual level of pre-primary teachers for seasonal change, the group who completed earth science while attending high school had a statistically significantly higher level of conceptual understanding than the group that did not complete it. Third, the ratio of misconceptions related to seasonal change of pre-primary teachers by gender was not significant, but the group who did not complete earth science while attending high school had a statistically significantly higher percentage of misconceptions than the group that completed it. As a result of the above examination, it is judged that the area of concepts, the level of conceptual understanding, and the misconceptions about seasonal changes of pre-primary teachers are more affected by the completion of earth science courses during high school than by gender differences.

  • An analysis was done on the “inquiry sections” of Earth Science chapters of 10th grade science textbooks. The Inquiry sections were classified into different types and the frequencies of basic process skills, integrated process skills, and inquiry activities were measured in section to find out whether they sufficiently satisfy the requirements based on the 7th National Curriculum. The number of selected science textbooks that have been used in high school for this study were eleven. The number of inquiry tasks were on an average of 24.0. The types of inquiry sections and the elements of basic and integrated process skills were different in every textbooks. The number of inquiry activities were also different and analyzed more than those presented. They were not integrated activities but presented as scientific process skills. The basic process skills and integrated process skills presented in textbooks were $16\%\;and\;77.2\%$, respectively. However, the distribution of two kinds of process skills were analyzed to be $45.6\%\;and\;55.4\%$, respectively. In the process skills, the frequencies of inferring $(49.5\%)$ and data interpretation (68.7%) were the highest; however, the other process skills including recognizing problem, formulating hypothesis and generalization were not even presented in any of the text books. Due to the lack of the definitions of Science process skills and inquiry activities in the 7th National Curriculum, each text book defined these terms differently. It suggests that the meaning of inquiry, science process skills, and inquiry activities should be operationally defined in the national curriculum and the criteria for construction of inquiry activities are required.

  • This study examined the dangerous elements in primary science textbooks and had some suggestions for the minimization of safety accidents in the science class experiments. The research results are as follows: 1) The rate of accident in the primary science experiments was not high, but potential for the outbreak of safety accidents was always present. 2) it is necessary to include safety contents on science textbooks. The survey revealed that only 18 percent of safety education materials include on science textbooks. 3) It will be desirable for science experiment lessons to include safety education materials for safety experiments. This could also help the students develop the right recognition and attitude regarding safety. 4) There was lack of safety devices those were required to be kept at science labs. The survey showed that about 20 percent of the schools had the experimental clothing. 5) Safety training is often conducted in an overly simplified manner, and no special time is allocated to it. In conclusion, to improve the problems pertaining to school safety accident, courses on safety training are essential as textbooks and teachers. Constant and systematic instructions on safety should be done in order to prevent potential safety accidents.
