The purpose of this study is to design and apply a pilot inquiry experiment focusing on the epistemological issues of scientific activities, and derive educational implications by analyzing experimental activities and reflective discussions. Three graduate students who major in science education participated in the study voluntarily. Participants showed the characteristics of stable enquiry in Experiment 1. However, the small but continuous changes in Experiment 2 led the experiment to a phase of fluid enquiry seeking new theories. Participants mobilized various resources, proposed new hypotheses, and models and requested additional experiments to verify them. In the process of reflective discussions, the participants led to the following three epistemological issues. First, at the beginning of the experiment, their observations were theoretically dependent. Second, when the observations were no longer coherent with theory, they face a crisis, and the adjustment of observation and theory proceeds. Third, stable enquiry and fluid enquiry are performed according to the relationship between observation and theory. The educational implications of school science inquiry based on the above process and results are as follows: First, this study shows that fluid enquiry can follow stable enquiry naturally, and examples of the activities are presented together. Second, in this study, it was confirmed that participants could draw up epistemological issues based on their experiences through reflective discussions following inquiry.

The research evaluated the effects of the improvements in scientific inquiry for elementary school students and focused on the development and application of the explicit and reflective learning strategy through observation and classification. The explicit and reflective learning strategy was modified and completed with the review of the experts after the development of the draft based on the theoretical approach. The students were evaluated for their academic achievements in scientific inquiry skills before and after taking the course. The results were as follows: First, the steps of the developed learning strategy (1) to motivate, (2) to explore reflectively, (3) to guide explicitly, (4) to inquire explicitly, and (5) to verify reflectively were set to reflect the verification. Second, the results of applying the developed model to the lessons based on the quantitative analysis was effective for observation and classification skills in the quest for improved performance of the whole (the sum of observation and classification, inquiry skills) and the observed features, but there was no effect on classification. Also, the lessons applied the developed teaching strategy and showed effectiveness in improving academic achievement. Particularly in analyzing the relationship between the academic achievement and exploration capabilities, in order to improve academic achievement, the importance of improving inquiry skills was found. Third, the qualitative analysis of teaching and learning strategy developed by applying the lessons of this teacher guide and small group activities through the explicit and reflective observation and classification of the student learning activities showed the significant improvement of ability of the scientific inquiry skills. In addition to the improvement in the abilities of the classification showed after the formation of the most basic observation skills of the scientific inquiry.

The purpose of this study is to propose a design model for school library based instruction under EduTech. EduTech-based education expands learning boundaries and requires new instructional environments and learning experiences for learner-centered deeper learning. Accordingly, this study modified the ADDIE model based on the system theory and presented a four-stage instructional design model (draft) consisting of 'analysis stage, preliminary learning and development stage, learning management stage, and team teaching evaluation stage.' This model reflects elements of flipped learning, the backward design model, and inquiry-based learning to develop of customized student materials and inquiry activities. In addition, the scope of learning was expanded to include prior learning, face-to-face learning, and additional learning to increase the diversity of collaboration and opportunities to utilize school library materials. Also, Several ways for school library based instruction within EduTec were proposed in terms of teacher librarians' expertise, school library space, budget, standard curriculum development, and comprehensive support system for reading education.

This study focused on the use of peer assessment activities to investigate its the impact on students' argumentation skills in argument-based inquiry. The participants of the study were 106 10th grade students (four classes). Two classes were assigned to the experimental group, and the other two classes were assigned to the comparative group. The experimental group was taught argument-based inquiry through the application of peer assessment activities. The comparative group was taught argument-based inquiry without peer assessments. At the claim and evidence stage, students were asked to evaluate whether peers' claims fit with the evidence and whether peers' explanation of the evidences validity was sufficient. The quality of argumentation used in the students' writing was different in each group. According to the analysis of the summary writing test, the results showed that the experimental group had a significantly higher mean score than the comparative group in argumentation components, including evidence and warrant/backing. In addition, the experimental group used better multimodal representation including explanation of evidence than the comparative group. The findings showed that argument-based inquiry applying peer assessment activities had an effect on the argumentation skills in students' writing.

The scope of this study is: (1) to review or summarize the theoretical explanations of diffusion; (2) to investigate the preservice teachers' understanding of diffusion utilizing the inquiry experiment of diffusion that was developed in this study. The data was collected through questionnaires given to 41 preservice teachers in 3 universities and interviews with 20 subjects from this population, who conducted the inquiry experiment. During the experiment, the data was collected from the students' reports and 3 small groups' audio/video recordings. To understand preservice teachers' conceptions, reports, audio/video recordings, questionnaires and interviews were analyzed and discussed with co-workers. The results follow: (1) The differences between effusion and diffusion as well as equal-pressure experiment and equal-flux one on diffusion were discussed; (2) Most preservice teachers understood effusion and diffusion connected to Graham's law of diffusion by rote and have misconceptions about the diffusion process; (3) They observed two kinds of diffusion experiments (equal-pressure and equal-flux) by inquiry experiment, but the majority of them failed to find conceptual differences between these experiments. After the inquiry experiment, about 40% of the samples modified their conceptions about diffusion.

The purpose of this study is to investigate elementary school students' understandings about scientific inquiry. Data were collected from 119 elementary students who are in the 4^th grade using the Views About Scientific Inquiry questionnaire for elementary students (VASI-E). We also conducted semi-structured interviews of 21 students from 119 students who responded to VASI-E. Students' responses were analyzed as naive, mixed, or informed views on each aspect of scientific inquiry that VASI-E includes. We found that, first, 53.8% of students have mixed views, and 30.3% of students have informed views, and 16% of students have naive views on the knowledge 'investigation begin with a question'. Second, 54.6% of students have naive views, 37.8% of students have mixed views, and 7.6% of students have informed views on the knowledge 'scientists use many methods to answer their questions.' Third, 47.9% of students have informed views, 34.5% of students have naive views, and 17.6% of students have mixed views on 'procedures guided by question asked.' Fourth, 55.5% of students have mixed views, 42% of students have informed views, and only 2.5% of students have naive views on 'conclusions must be consistent with data and explanations come from data and prior knowledge.' Based on the results, implications for teaching and learning scientific inquiry at elementary level in Korea were discussed.

This study attempted to understand the characteristics of pedagogic activities performed by pre-service elementary school teachers. To this end, it applied Algodoo simulations to analyze the actions of students and obtain educational implications for optical learning. The study's participants comprised 79 first-year students enrolled in a teacher training college. Their activities could be classified as representation reproductions, verification experiments, and inquiry experiments. Students who performed representation reproduction exercises replicated renowned and authoritative exemplars, apprehending and demonstrating their principal features through simulations. Students performing verification experiments attempted to validate previously learned optical concepts by reviewing the relevant theoretical contexts. Such students primarily conducted simple experiments. Students accomplishing inquiry experiments used simulations to explore phenomena they did not know. Some of them even investigated optical phenomena beyond the domain of general physics. The above results confirmed that free optical experiments performed using Algodoo can effectively denote starting points for learners to engage in activities at varying levels. Additionally, students require assistance from instructors in addressing queries about the application of the principles and models related to optics. This study suggests ways in which instructors should help students at each level of activity. Additionally, the paper presents examples of varying levels of inquiry-related activities available on Algodoo. It also discusses the advantages and disadvantages of performing inquiry-based activities on Algodoo and suggests ways of enhancing the learning achieved through this platform.

To respond to the announcement of the revised version of science curriculum early this year, it has been necessary to develop new science textbooks which can be appropriate and effective to achieve the goals of the revised curriculum. The system of new textbooks needs to embrace the concerns of cognitive development in scientific knowledge, skills, and attitudes as well as social and cultural demands in the rapidly changing society. To develop an innovative framework of science textbooks, we examined previous studies on textbook analysis in Korea and analyzed science textbooks in the United States, Singapore, and Japan. We analyzed various ways of introducing and developing conceptual knowledge, leading scientific inquiry skills and process, enhancing scientific attitudes toward science, technology, society and the environment in those science textbooks. In the process of framing the structures of textbooks, we focused on ways of increasing educational effects of visualized texts, leaners' interest, user-friendly procedure, scientific inquiry, effectiveness of hands-on activities, scientific reading and writing skills, and usage of workbook. Based on those aspects and analyses of textbooks, we attempted to propose a feasible framework of Grade $3{\sim}4$ Science textbook which can effectively respond to the educational changes and demands in the local and global society.
