Inquiry-centered education is important in science education, but in the actual education field, scientific research is being done in a uniform manner due to realistic difficulties. In this study, we use RS (Reverse Science) as a secondary chemistry class to provide opportunities for students to engage in inquiry learning and scientific thinking through process-oriented activities. In this study, we developed and applied it to explore the effects on the scientific inquiry abilities of middle school students and checked the students' perception of it. For the application of the program, 128 students were selected from 6 classes of the 2nd grade in D district middle school, 64 from the experimental group and 64 from the comparative group. The experimental group taught RSP-based the chemistry inquiry programs and the comparative group taught instructor-led classes and verification experiments on the same topic over the seventh hour with three themes. In addition, we analyzed the results of the pre- and post-test by using the science inquiry ability test, and discussed the effects of the program based on the students' perceptions through class observation, student activity area, questionnaire and interview. As a result, the class using the program showed statistically significant changes in the science inquiry ability of secondary school students. Specifically, the experimental group was found to be significant in its prediction among the subcomponents of basic exploration ability compared to the comparative group. The differences have also been shown to be significant in terms of data translation, hypothesis setup and variable control, which are subcomponents of integrated exploration capabilities (p <. 05). In addition, students became interested in the process of creating the theory of science, and were highly interested in collaborating with their friends. It also provided students with opportunities to experience scientific thinking through process-oriented inquiry. Finally, based on the positive impact of the RSP-based chemistry inquiry program on students, we were able to identify the potential use of the program.

This study was performed the analysis of four kinds of common science textbooks based on the 6th curriculum. Particularly, inquiry activity part was analyzed by the three dimension framework which consists of inquiry content dimension, inquiry process dimension and inquiry context dimension. In the analysis of the inquiry content dimension of inquiry activities, the contents revised by 6th curriculum of common science textbook was accomplished through various inquiry activities. The number of inquiry activity in four textbooks was similar as about 16. The For the analysis of inquiry process dimension, 'interpreting data and formulating generalizations' category (39.1%) was most emphasized and the categories of 'observation and measuring'(30.8%), and 'building, testing and revising the theoretical model' (16.5 %), 'seeing a problem and seeking ways to solve it' (13.5%) follow in order. As for the analysis of the inquiry context dimension, the proportion of STS related contents in inquiry activities was only 18%. So, we propose that STS related contents would increase the proportion for the following textbook.

The purpose of this study was to analysis characteristics and changes of epistemic thinking in middle school students on class-argument activities in an argument-based inquiry(ABI) science class. Data was collected from class recording video and activity worksheets of five subjects argument-based inquiry. Results of the analysis of student epistemic cognition characteristics show that experimental data was presented the most as evidence, and depending on the ABI activity, personal experience-based evidence and evidence based on scientific principles were used. As a result of analyzing the changes between claims made before and after class argumentations on five ABI activities in an argument-based inquiry science class, student claim modifications could be classified, according to reasons for the modification, into three types: correcting incorrect claims, clarifying unclear content, and expanding the concept.

In this paper, both content analysis and Romey analysis were employed to analyze 'Basic Information Technology' textbooks in technical high schools. Not only was the content analysis employed to study the organization and contents of the textbooks, but also the Romey analysis was applied so as to determine inquisitive tendency on four factors - text, data, activity and evaluation. The results from content analysis showed that the total number of pages, reading material, the number of concepts introduced in each section, and the use of application software demonstrated a discrepancy among textbooks. Also, Romey analysis showed that while the section 'text' was written with relatively low inquiry tendency for its authoritative tone, two textbooks showed high inquisitive tendency for section 'activity'. Finally, based on the obtained results, the ways to improve 'Basic Information Technology' textbooks were proposed.

The purpose of this study was to examine the features of the standards of classification, prediction and reasoning in foreign national science standards and the characteristics of these inquiry processes in the Korean science textbooks. The inquiry process of classification was found less frequently rather than observation and measurement. 'The classification of one character' was much more contained than the higher level of classification, 'the classification of composit character'. For the inquiry process of prediction, most of prediction was 'prediction from experiment result'. In the level of prediction, 'basic prediction' was found more frequently than 'operation prediction'. The inquiry process of reasoning was found more frequently than classification and prediction and was increased in the higher grade textbooks. In the level of reasoning, the higher grade textbooks included 'secondary reasoning' rather than 'simple reasoning'.

The purpose of this study was to develop a teaching strategy focused on science writing and to investigate its effects on enhancing students' creative thinking skills. In advance, students in the experiment were led to write by inquiry elements. And students in the experiment group were taught by science writing strategy. Students in the control group were taught by traditional lecture-based instructions. The program was implemented over a semester. The results indicated that the experimental group presented statistically meaningful improvement in creative thinking skills(p<.05). Especially, science writing was effective on fluency and flexibility development(p<.05). This study suggests that science writing can be effective for improvement of creative thinking skills.

Teachers often encounter challenges in supporting students with question generation and the development of investigation plans in sensemaking activities. A primary challenge stems from the ambiguity surrounding how students apply their conceptual understandings in this process. This study aims to explore how students apply their conceptual understandings to generate questions and design investigation processes in a sensemaking activity. Two types of student group activities were identified and examined for comparison: One focused on designing a process to achieve the goal of sensemaking, and the other focused on following the step-by-step scientific inquiry procedures. The design of investigation process in each group was concretized with epistemic criteria used for evaluating the designs. The students' use of conceptual understandings in discussions around each was then examined. The findings reveal three epistemic criteria employed in generating questions and designing investigation processes. First, the students examined the interestingness of natural phenomena, using their conceptual understandings of the structure and function of entities within natural phenomena to identify a target phenomenon. This process involved verifying their existing knowledge to determine the need for new understanding. The second criterion was the feasibility of investigating specific variables with the given resources. Here, the students relied on their conceptual understandings of the structure and function of entities corresponding to each variable to assess whether each variable could be investigated. The third epistemic criterion involved examining whether the factors of target phenomena expressed in everyday terms could be translated into observable variables capable of explaining the phenomena. Conceptual understandings related to the function of entities were used to translate everyday expressions into observable variables and vice versa. The students' conceptual understanding of a comprehensive mechanism was used to connect the elements of the phenomenon and use the elements as potential factors to explain the target phenomenon. In the case where the students focused on carrying out step-by-step procedures, data collection feasibility was the sole epistemic criterion guiding the design. This study contributes to elucidating how the process of a sensemaking activity can be developed in the science classroom and developing conceptual supports for designing sensemaking activities that align with students' perspectives.

Purpose of the Study : This research aims to examine the core values of ESG (Environmental, Social, and Governance) from a Christian perspective and explore the direction of Christian education that fosters character traits such as service, compassion, responsibility, and sharing through the process of design thinking. Content and Method of the Study : By investigating the background and definition of ESG, ESG practices in businesses, and the current status and values of ESG education in universities, this study examined the core values of ESG from a Christian perspective. Subsequently, the study explored and proposed directions for applying ESG education methods infused with character traits such as service, compassion, responsibility, and sharing through the process of design thinking. Conclusion and Recommendations : Through this study, the core values of ESG have been derived as elements from a Christian perspective, and exploration has been made on how to integrate them into the design thinking process. Consequently, this study has identified the potential to integrate ESG into the design thinking process with a focus on elements from the perspective of Christian education. This could serve as foundational material for education seeking to apply ESG through the integration of design thinking, and it is hoped that it will be helpful as a basis for further research. Subsequent studies should aim to construct a more systematic framework for the direction proposed in this study through expert reviews.

The purpose of this study is to consider the implications of science experiment in class and to seek a direction for its improvement. For this purpose, Science textbooks, teachers' cognitions, and classroom activities have been analyzed to find out how many and what kind of levels of inquiry elements are included in those. In this study, 22 teachers have participated in the questionnaire to investigate their perception about experiment class, and the two instruction cases in two classes of 9th grade have also been analyzed. Results show that most of the textbooks have included questioning, evidence collecting, explanation of phenomena, and connection with existing scientific knowledge. But the elements of communication and justification have been few. Most levels of the inquiry are teacher-led. Although the teachers thought communication and justification are important, their classroom activities does not coalesce with their thoughts. The students mostly spend their time with connecting evidence, they hardly explain the phenomenon based on the proofs as the results of experiment, and the activities of connection with the existing scientific knowledge, and communication and justification.
