Research Projects allow students to experience of scientific research by conducting experiments on specific scientific subjects and writing reports. The process of research begins as students find and propose research questions and its importance has been consistently emphasized. In this study, we developed various strategies to support students to draw research questions and applied to each phase. We analyzed how students' research questions were developed at different phases. The program consists of five phases, such as (1) Exploration, (2) Literature Review and Data Collection, (3) Modification and Extension, (4) Sharing and Evaluation, (5) Final Selection and Research Plan. The program was applied to high school Research Project for 12 hours. A total of 13 students were divided into four groups of 3-4 students and conducted researches. The results of each student's research process and final research plans were then collected and analyzed. The overall quality of research questions produced by the students showed improvement in each phase. Each strategy improved in various aspects of the research questions at each level. Students were able to find their own area of interest in the 'Exploration' phase and then they began to suggest verifiable plans in the 'Literature and Data Collection' phase. They were able to find a variety of variables under the 'Modification and Extension' phase, whereas the precision of research questions improved in the 'Sharing and Evaluation' and the 'Final Selection and Research Plan' phase.

The purpose of this study is to analyze the current status of the second year of application of Integrated Science and Science Laboratory Experiments, which are common courses of high school, and to explore suggestions for curriculum development in the future. To this end, the results of the survey of a total of 244 science-core and general high schools were compared with the survey result of 2018 school year. In addition, in-depth interviews were conducted with nine science teachers of the focus group to discuss the current state of curriculum implementation. According to the results, as in the first year, most of the Integrated Science courses were implemented in 6-8 units, and in most schools the number of teachers in charge of Integrated Science per class were 3-4. In the teacher's focus group interview, teachers insisted that Integrated Science requires integrated teaching approaches and is good for generating students' interest, but it is difficult to implement process-based assessment due to issues such as ensuring fairness of assessment. Most of Science Laboratory Experiments courses were implemented in two semesters, one unit per semester, and there was little link between Integrated Science and Science Laboratory Experiments because of the different teaching staff. The school life record entry method of Science Laboratory Experiments has been changed to criterion-based assessment starting in 2019, so students' satisfaction or flow of classes is much better than expected, and teachers can teach without burden. Based on the research results, ways to support the settlement of Integrated Science and Science Laboratory Experiments as common subjects, and ways to improve those subjects in the next curriculum revision were suggested.

교사의 과학 탐구 지도에 대한 인식은 실제 수업에서 탐구 지도를 수행하는데 중요한 역할을 할 수 있다. 따라서 교사들이 과학 탐구를 어떻게 인식하는지 이해할 필요가 있다. 이 연구에서는 한국, 싱가포르, 미국 세 국가의 초등교사를 대상으로 과학 탐구 지도에 대한 인식을 조사하였다. 세 국가는 과학교육과정에서 탐구를 강조해 온 역사와 설명 방식이 다르며 전반적인 교육적 상황 또한 상이하다. 총 100명의 초등교사(한국 34, 싱가포르 35, 미국31)를 대상으로 설문을 실시하였으며 설문은 구체적인 교수 상황을 서술하는 교수 시나리오, 이상적인 탐구 수업에 대한 내러티브 쓰기로 구성되었다. 데이터는 외적 기준과 내적 관점 모두에서 분석되었다. 연구 결과 교사들의 과학 탐구 지도에 대한 인식은 전반적으로 전통적 견해에 머무르고 있는 특징을 보였다. 그러나 각 국가의 교육과정에서 탐구가 서술되고 강조된 방식에 따라 차이가 나타나기도 하였다. 이러한 결과가 교사교육에 주는 시사점을 논의하였다.

The purpose of this study is to investigate theoretically the meaning and features of the Community of Inquiry (CoI) based on the views of Peirce and Dewey, and to explore the implications of CoI in science education. The meaning and features of CoI are: (a) inquiry in CoI is initiated with faithful doubt; (b) inquiry in CoI finishes with faithful belief; (c) inquiry in CoI attempts to find out the best explanation and solution regarding the practical effects of objects; (d) as an ideal community, CoI is required to be one that inquires continuously without definite limits; (e) as an actual community, CoI requires its members' open communication to find the best explanation and solution. Based on these features of CoI, the Community of Inquiry in Science Classroom (CoI-SC), "the classroom community for the purpose of transforming the state of faithful doubt into the state of faithful belief, in relation to natural phenomena or objects, and where the members share objectives as participants continuously attempt to find out the best explanation and solution by open communication, considering fallibility and the practical effects of objects", was suggested. The condition for implementation of the CoI-SC, "'interest', 'openness', 'rigor', 'fallibilism', 'participation', 'inquiry without definite limits'", were also suggested. Finally, several suggestions for the science curriculum were given.

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.

In this study, the 'extended science investigation' was conceptualized as a comprehensive science investigation contrasted with exercise of process and skill component and cookbook style experiment. The extended investigation tasks can be characterized with practical context. openness and continuity. The purpose of this study is to describe the change of students' cognitive engagement while they perform the extended science investigations and to explore how the characteristics of the extended investigation tasks affect the students' cognitive engagement. 128 7th graders attending coeducational school in Seoul were participated in this study. The questionnaire was implemented repeatedly to monitor students' cognitive engagement. And ten students were interviewed to explore the cause of the change of cognitive engagement. The result showed that there was no difference between directive traditional investigations in textbook and developed extended investigations in understanding of the content and whole process of investigations but participants' commitment was increased significantly in the extended science investigations. Especially the extent of students' understanding and commitment became higher in the second half than in the first half of the extended science investigations. The openness of the extended investigation tasks contributed on the increase of commitment. And the continuity of the tasks contributed on the increase of students' understanding in the second half of the extended science investigations.

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 cultivation of scientific literacy in recent science education can be improved by experiencing and understanding scientific inquiry by which scientific knowledge is formed. The National Research Council(NRC) released the Next Generation Science Standards (NGSS) including 8 practices of science that help students experience scientists' inquiry and subdividing achievement standards to perform 8 practices of science into by grade clusters. This study was intended to examine science inquiry activities included in 4 high school chemistry II textbooks developed by the 2009 revised curriculum using the 8 scientific practices and their achievement standards for 9th-12th grade. The science inquiry activities and the science practices included in the 4 textbooks were 173 and 678. The science practices included in the inquiry activities of 4 textbooks included the most ‘analyzing and interpreting data.’ The ‘engaging in argument from evidence’, ‘Obtaining, Evaluating, and Communicating Information’ were less than other practices. The ‘asking questions and defining problem’ and ‘developing and using models’ were not nearly included in the 4 high school chemistry II textbooks.

This study aims to analyze the aspect of inquiry activity for seven national science textbooks, which were recently authorized and developed for elementary schools. The study reviewed seven of the abovementioned textbooks, which were introduced to the authorized textbook system for 2022 in elementary schools. In-depth analysis was conducted on inquiry activities, which were frequently emphasized since the third curriculum. A chapter entitled "Stratum and Fossils" was selected to analyze the detailed types of inquiry activity using the framework. First, analysis was conducted on six types of inquiry activity. The result indicated that two out of seven inquiry activities different among the national and authorized textbooks. In other words, the two slightly differed from the inquiry activities presented in national textbooks. It was not reasonable that the introduction of the authorized textbook exerted an effect on the increase of autonomy and variety of teaching and learning activities compared with those of national textbooks. Second, science process skills, material, and inquiry process were established as standards for the detailed types of inquiry activity. The study demonstrated a slight difference among textbooks in terms of material and inquiry process, whereas the inquiry activities of the seven authorized textbooks were the same or similar. This finding indicated that students could experience seven types of inquiry activities. Moreover, the study examined inquiry activities related to essential learning contents in detail and found that there were more diverse than types of inquiry activities.

This study explores how the positioning of two pre-service science teachers (PSTs) is reflected in their different epistemic understandings of inquiry-based lessons. We collected the PSTs' products during their design and enactment of an inquiry-based lesson and recorded their practices in the enacted lesson. Interviews were recorded and transcribed for analysis. The results indicate that one PST, Dohyung was positioned as a subject of evaluation throughout the course and the other, Jinwoo, was positioned as a preservice teacher and a subject of evaluation. Their positions were reflected in their epistemic understandings of inquiry-based lessons, which were developed when designing these lessons. During lesson design, both PSTs showed a shared understanding; they explained inquiry-based lessons as students setting and evaluating hypotheses under teachers' guidance. However, as they faced unexpected situations during lesson enactment, they developed different epistemic understandings. To receive a good grade, Dohyung showed a strong preference for anticipating situations that could occur in class and planning responses to them. He understood inquiry-based lessons as ones in which students conduct experiments to produce results expected by the teacher. On the other hand, Jinwoo emphasized the reasoning process based on students' prior knowledge and explained inquiry-based lessons as ones in which students construct new knowledge through a scientific reasoning process based on their knowledge. The findings of this study will contribute to developing strategies to support PSTs' development of their epistemic understandings of knowledge construction in inquiry-based lessons.
