The purpose of this paper was to analyze the kinds and roles of multimedia materials in E-works that are distributed with elementary textbooks (3~6 grade) of the 2009 revised science curriculum. Five criteria (forms, goals, key competencies, inquiry process, running time) were set for this. The sample of the paper was the 784 multimedia materials in E-works of elementary science textbooks (3~6 grade) of the 2009 revised science curriculum. The results of the multimedia materials analysis are as follows: The result of the material forms of multimedia is that the form of highest ratio is text type. But all forms were used evenly in E-work. 56.2% of the multimedia materials are for "inquiry" in the goal criteria, and 65.0% of the multimedia materials are related to "science inquiry" in the key competencies criteria. Two facts indicate many multimedia is used to develop students' inquiry ability. However the ratio of multimedia materials in motivation step is higher than that in inquiry activity step. In analysis of running time, the ratio of "under 5 min" multimedia materials is the highest. But, the ratio of 5~10 min multimedia materials in inquiry part is higher than that in motivation part in The Chi-square test between "running time" and "parts" that consist of motivation part and inquiry part. Through the analysis of module and the categorizing the multimedia materials, we found that the multimedia materials play eleven roles in E-works that are distributed with elementary textbooks.
Typhoons are representative oceanic and atmospheric phenomena that cause interactions within the Earth's system with diverse influences. In recent decades, the typhoons have tended to strengthen due to rapidly changing climate. The 2022 revised science curriculum emphasizes the importance of teaching-learning activities using advanced science and technology to cultivate digital literacy as a citizen of the future society. Therefore, it is necessary to solve the temporal and spatial limitations of textbook illustrations and to develop effective instructional materials using global-scale big data covered in the field of earth science. In this study, according to the procedure of the PDIE (Preparation, Development, Implementation, Evaluation) model, the inquiry activity data was developed to visualize the track of the typhoon using the image data of GK-2A. In the preparatory stage, the 2015 and 2022 revised curriculum and the contents of the inquiry activities of the current textbooks were analyzed. In the development stage, inquiry activities were organized into a series of processes that can collect, process, visualize, and analyze observational data, and a GUI (Graphic User Interface)-based visualization program that can derive results with a simple operation was created. In the implementation and evaluation stage, classes were conducted with students, and classes using code and GUI programs were conducted respectively to compare the characteristics of each activity and confirm its applicability in the school field. The class materials presented in this study enable exploratory activities using actual observation data without professional programming knowledge which is expected to contribute to students' understanding and digital literacy in the field of earth science.
This study was conducted to analyze the relationships between terms, learning concepts and inquiries in ocean unit, the National Common Basic Curriculum. The several science textbooks were selected to use for study, written in accordance with the 7 current national curriculum for the fourth grade of elementary school, the seventh of middle school and the tenth of high school. The higher the school level becomes, the frequencies of using terms related with ocean region get. The explanation of terms, however, has a tendency to be less frequent in the high school level. In the perspective of learning concept, there are more concrete concepts than formal concepts regardless of school level. Pure scientific context appears most often in inquiry contest through the whole course of every school level. In respect to inquiry process, the frequency of integrative inquiry process is on the increase as the school level gets higher. From the viewpoint of inquiry activity, there have been a lot of discussions, experiments and investigations in every school level, while high school does not the present any field study and project. Through these result, it is considered that the explanation of main terms is inevitable in the textbooks as basic educational material without regard to school level. In learning concept and inquiry context, a well-rounded learning is needed in relation to students' cognitive development and science-technology-society. Especially for the inquiry activity of earth science education, the educational effect is remarkable through field study; its appropriate application is required, accordingly.

The purpose of this study is to compare inquiry activities in science textbooks' physics contents for Korean secondary schools with those of Singapore in order to provide a reference for further improvement of inquiry activities in Korean science textbooks. We analyzed inquiry activities using the framework of Millar et al.(1998) and Chinn & Malhotra (2002). The results of this study are as follows: There are differences between Korean and Singaporean inquiry activities in the area of 'learning objectives', 'students' thinking activities' and 'degree of openness'. In the area of 'learning objectives', the Korean textbooks have more activities associated with the learning of science content than those in Singaporean, whereas the Singaporean textbooks have more activities associated with the processes of scientific inquiry than in Korean textbooks. In the area of 'students' thinking activities', the Singaporean textbooks have activities like 'test a prediction', which Korean textbooks lack. The 'degree of openness' is higher in Singaporean textbooks than in Korean textbooks. And some differences in the area of 'authentic scientific inquiry' between Korean and Singaporean textbooks were also found. While the Korean textbooks do not have any activities associated with 'generating research questions', the Singaporean ones feature such activities. In the area of 'designing studies', the Singaporean textbooks have activities corresponding to 'selecting variables' and 'controlling variables', while the Korean ones never have such activities. The results of this study imply that it is necessary to balance inquiry activities in the area of 'learning objectives', 'students' thinking activities' and 'degree of openness', and to present activities close to authentic scientific inquiry in inquiry activities in textbooks.

The purpose of this study is to analyze classroom norms formed in inquiry activities of elementary science classes and to consider about the actual problems in enacting school science inquiry. Focusing on the inquiry activity cases of two classes, the data were collected through classroom observation, student interview, teacher interview and questionnaires. Firstly, classroom norms were categorized into three categories theoretically: norms for behavior guidance; general academic norms; and scientific inquiry academic norms. The subcategory norms of each category were extracted inductively and the features, the causes of formation, and the influences on inquiry of each norm were also analyzed. Based on the analyses on classroom norms, the researchers identified three actual problems in enacting school science inquiry. First, the collective traits of school science inquiry caused structural problems in science classrooms. Second, teachers used their authorities in different ways according to phases of instructions. Third, the conflict cases were reported between general values for education and specific values for science inquiry. Educational implications are discussed in terms of the practices of school science inquiry and of the understanding classroom phenomena.
The purpose of this study was to explore the elementary school teachers' perceptions about making a model of volcanic activity. Thirty elementary teachers participated in the study after they in which they conducted the experiment of "Making a Model of Volcanic activity". A questionnaire was used to investigate how the teachers understood the strengths and weaknesses of the experiment in terms of the goals of school science inquiry. The results showed that 50-60% of the teachers were able to conduct the experiment as guided in the textbook regardless of their career or area of concentration. The teachers perceived that the experiment of current textbook was safe and useful for students to develop their creativity. However, they pointed out three major weaknesses of the textbook experiment: First, the textbook experiment does not clearly present the main purpose of the activity. Second, it does not appropriately reflect the natural volcanic activity. Third, it is a merely simple craft activity. In addition, the teachers agreed that the main goals of school science inquiry are the application of scientific knowledge, development of inquiry skills and cultivation of student's curiosity. However, the teachers perceived that the experiment of current textbook did not meet these three goals. They suggest that the experiment reflect the nature of real volcanic activities.

The purpose of this study was to investigate science related attitudes, scientific knowledge, and scientific inquiry skills of middle school students when HASA(3H-hand, head, heart-at Science Activity) programs were applied to them. The HASA program is a program developed as an alternative to the current educational system. There are some basic principles for developing this program; it should be fun or of interest to students; it should be a manual activity that students can do with their own hands; it should be found in everyday life; and it's final goal is to improve scientific attitudes. The learning program consists of a series of 10 activities (10 periods). One hundred and sixty-two middle school students (7th graders) participated in the study and were divided into three groups. The HASA group (N=58) was exposed to the HASA program and the Lecture group (N=59) was exposed to the expository method of learning scientific knowledge, and the Lab group (N=45) was exposed to the experiment through textbooks. The results were as follows: 1) the HASA group was marginally higher than others but with no significant difference in science related attitudes; 2) the Lecture group had a significantly greater level of achievement in science knowledge; 3) There was no difference in the improvement of scientific inquiry skills.
The purpose of this study was to investigate elementary gifted students' characteristics of observing and inferring in the inquiry activities. For this study, 40 students of the 4th and 5th grades participated in inquiry activities where the strata were developed well, Haenam Uhangri province. And we analyzed the outcomes of students' inquiry activities. The results are as follows. First, 119 units as observing results were obtained, but most of them showed that they were not focused on the portion of stratus, but that they were implicated in whole stratus as observing object. Second, 90 units were collected with reasoning results, but 4 units of them were wrong in constructing of inferring. Based on outcomes of students' inferring, elementary students preferred to apply deductive inferring method rather than use abductive inferring. Third, only 39 of 119 units acquired from observing were used for constructing inferring and 80 which were discovered from observing activities were discarded without applying of inquiry activities. Fourth, about 42% of students' inferring results were in accord with them of the geologists. But 58% views which didn't agree with geologists showed that they were applied to misconceptions among constructing inferring.

The purpose of this study is to investigate pre-service science teachers' difficulties in the 'inquiry mentoring' program, which was developed to improve pre-service science teachers' inquiry teaching ability. For this study, I developed the 'inquiry mentoring' program in which pre-service science teachers taught high school students. This program was adapted for 2.5 months, and 45 pre-service science teachers participated and taught 44 high school students. During this program, pre-service science teachers kept 'mentor diaries' and wrote 'mentoring reports' at the end of the program. Interviews were conducted with all pre-service science teachers. Results are as follows: first, pre-service science teachers thought that the difficulties in inquiry mentoring resulted from their inadequacy (mentor factor) than students' inadequacy (mentee factor). Second, pre-service science teachers perceived their lack of cognitive ability, inquiry ability and teaching ability as a mentor factor. Third, pre-service science teachers thought that they had difficulties in students' differences and lack of activity as a mentee factor. Fourth, they described difficulties caused by emotional distance as well as physical distance as an interaction factor. They also mentioned the difficulties related to teaching range and online interaction. Fifth, pre-service science teachers expressed a sense of frustration with the inquiry environment. Additionally, some implications were discussed for pre-service science teacher education through the 'inquiry mentoring' program.
The study presents preliminary research on how science activities focusing on problem recognition worked and affected students' perception of their learning environment in a sixth science classroom. The science activities were based on the Science Writing Heuristic (SWH) which was suggested by Keys, Hand, Prain & Collins (1999), where problem recognition was an important part of scientific inquiry. For developing the working sheets for the modified SWH in this study, analyses of target units of 6th grade science curriculum in the aspects of problem recognition were conducted. After consecutive 6 classes with the developed working sheets for sixth graders, the student working sheets for each lesson were collected and analyzed. In order to investigate the developed units' affect on student learning, students' perceptions of their learning environment were administered before and after the applied classes. Students working sheets and questionnaires on their perceptions of learning environment indicated that students perceived that the science activities were more student-centered classes where students had active discussion and dialogue with one another giving them more chances to actively take part in the class as well as they used more properly recognized their inquiry problem.
