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.

This study aims to analyze criteria and characteristics for preservice elementary teachers' critiques of their peers' inquiry-based instruction. This study reviews critiques written by 31 preservice elementary teachers enrolled in an elementary school science inquiry methods course wherein the teachers designed and implemented inquiry-based instruction. These preservice teachers participated in inquiry-based instruction as if they were elementary students and then evaluated their peers' instruction. Analysis of the critiques reveals that preservice teachers evaluated their peers' instruction on the following criteria: instruction context, science content, teaching strategies, students, instructional goals, non-verbal attitude, and assessment. Their beliefs about teaching science inquiry were reflected in the critiques. Additionally, it was found that four orientation for teaching inquiry-didactic, academic rigor, activity-driven, inquiry orientation-reflected in critiques; some of critiques held more than one of these orientations. And they did not merely criticize but suggested alternatives to general teaching strategies; furthermore, of inquiry-instruction specific teaching strategies. They showed higher epistemic understanding of inquiry-based instruction after mid-term demonstrations. The evidence demonstrated that the proportion of critiques specifically about inquiry-based instruction increased after the mid-term demonstrations. Moreover, the post mid-term critiques emphasized interaction between students as well as understanding of the nature of science. These findings could provide implication for teaching inquiry and criticizing others' instruction as part of elementary school science courses in preservice elementary teacher education.

This study explore characteristics of teaching orientation and pck of science teachers in online-offline mixed learning environment. Data consisted of open-ended survey, semi-structured interview, class observation, field notes from 12 science teachers. We categorized teaching orientation considering both science education goals and science teaching·learning orientation. There were 8 different teaching orientations such as 'understanding science concepts-lecture centered' 'constructing science concepts-inquiry based' 'applying science concepts and inquiry-inquiry based' 'applying science concepts and inquiry-lectured centered' 'analyzing and judging science information-inquiry based' 'developing scientific attitude-inquiry based' 'developing scientific attitude-lecture centered' and 'developing perception of interrelationships among science, technology, and society-inquiry based'. Teachers with inquiry based teaching·learning orientation seemed to have knowledge of science curriculum specific to online learning environment for student inquiry. While teachers with 'understanding science concepts-lecture centered' teaching orientation appeared to have questioning strategy of checking student understanding and strategy of repeating a lecture, teachers with 'constructing science concepts-inquiry based' teaching orientation appeared to have knowledge of instructional strategies to perform online group activities targeting student construction of knowledge and to replace face-to-face group activities with virtual experiments and individual experiments. While teachers with 'understanding science concepts-lecture centered' teaching orientation did not show knowledge of student science learning, teachers with 'constructing science concepts-inquiry based' teaching orientation appeared to have knowledge of student difficulties in inquiry based learning.

Despite the continuing emphasis on the importance of scientific inquiry, research studies have commented that authentic scientific inquiry is not implemented in school science classroom due to a lack of understanding of scientific inquiry by the teacher. The purpose of this study is to investigate understanding of scientific inquiry developed by beginning teachers through open-ended questionnaire and semi-structured interview. They voluntarily set up the goal of inquiry-based classes, planned inquiry-based classes, shared and reflected their teaching experience in professional learning community for more than a year. It appeared that participant teachers understood scientific inquiry as 'what scientists do', 'process how students do science' and 'science teaching methods.' All teacher participants described scientific inquiry as 'what scientists do', and understood 'the process of doing scientific investigation to solve problems related to natural phenomenon' and 'the process of constructing scientific knowledge using scientific practice.' Two participant teachers seemed to understand scientific inquiry as a 'teaching method' based on the understanding of the process how scientists or students do science. Participant teachers had a limited understanding of scientific inquiry that it is the same as laboratory works or hands-on activities prior to engaging the professional learning community, but they developed an understanding of scientific inquiry that there are various ways to conduct scientific inquiry after engaging in professional learning community.

In this study, explicit Teaching and Learning strategy for middle school students were developed to improve basic science process skills. After applying these strategy in an actual class, the effects of Teaching and Learning strategy and change of students were analyzed. Explicit Teaching and Learning strategy to improve basic science process skills are developed based on analyzing preceding research. The use of application criteria for class of basic science process skills combined with explicit Teaching and Learning strategy, it is sought for the explicit instructional procedures of said skills. After analyzing the class in which explicit Teaching and Learning strategy were demonstrated, students reported that they were able to comprehend basic science process skills more effectively through the stages of explicit explaining and independent practice. The showing demonstration stage was heavily emphasized by the teacher in this class. Analysis of students' understanding degree about basic science process skills, most of them show positive outcome. Another analysis of ripple effect on daily life and other subjects, it is found that students could have the attitude to make use of science process skills for themselves. Through the result of study, it is found that explicit Teaching and Learning strategy that are developed from this study are an effective way to comprehension students' basic science process skills. Thus, continued study is needed to develop and spread explicit Teaching and Learning strategy of science process skills to be applicable in actual classes in secondary schools.

The purpose of this study is to examine epistemic thinking in middle school students in an argument-based inquiry science class. Participants of the study were 93 9th grade students from four classes of a middle school in a metropolitan city. Observations were made over one semester during which argument-based inquiry lessons on five subjects were conducted. Data was collected from argument-based inquiry activity worksheets and student questionnaires. After analysis of epistemic thinking in the written reflections, students were found to have the highest frequency of epistemic metacognitive skills, followed by epistemic cognition, epistemic metacognitive experience, and epistemic metacognitive knowledge. While investigating the effects of an argument-based inquiry science class on student epistemic thinking and after analysis of the reflections written for the first ABI activity and the fifth ABI activity, we found that all of the sub-elements of epistemic thinking have increased. The rate of growth for epistemic cognition is greatest, followed by epistemic metacognitive knowledge and epistemic metacognitive skills. Assessed for epistemic thinking, the level of epistemic thinking improved over the course of the argument-based inquiry science class. The results of the survey show that students actively participating and being recognized for their active participation in the argument-based inquiry science class are helpful in understanding scientific knowledge. Therefore, an argument-based inquiry science class is a teaching and learning program that allows students to understand and experience the epistemic nature of scientific knowledge and its construction through collaboration and agreement.

This study aims to explore science inquiry teaching efficacy that middle school science teachers implementing science practice-based teaching for one year recognized as necessary for teaching science through science practice. Examining interview data in this study, science inquiry teaching efficacy was identified in both planning and implementing in the areas of managing efficacy, instructional strategy efficacy, and content knowledge efficacy. In planning science inquiry instruction, there is science curriculum management efficacy under managing efficacy. There are the efficacy of outlining science inquiry lesson, efficacy of organizing science practice, efficacy of questioning for science practice, and efficacy of understanding student science practice under instructional strategy efficacy. Under the content knowledge efficacy are contents and science practice understanding efficacy and core ideas efficacy. In implementing science inquiry instruction, managing efficacy includes science practice time management efficacy and science practice classroom culture efficacy. Instructional strategy efficacy includes efficacy of motivating student science practice, efficacy of responding to student science practice, efficacy of stimulating student active thinking, efficacy of student active engagement in argumentation, efficacy of evaluating student participation. No content knowledge efficacy have been identified in implementing science inquiry instruction.

In a situation in which online classes were suddenly introduced due to COVID-19, there were many cases where learners did not properly learn science process skills that were not presented in the achievement standards for reasons such as reducing the number of class hours. It is difficult to expect positive science inquiry ability and science attitude from learners who have entered middle school without understanding the process skills. Therefore, in this study, the effect on science inquiry ability and science attitude was investigated by developing worksheets with enhanced process skills and applying it to learner-centered teaching linked online and offline. As a result, it was confirmed that there was a statistically significant positive difference between both. Based on this research, it is expected that students will pay attention to the process skills, which is the basis of science subjects, and continue to experience the process skills through learning-centered classes.

The purpose of this study is to develop an inquiry sheet for the contents of the clothing curriculum of home economics in middle schools using a physical fiber Identification method to increase students' interests in and understanding of clothing materials. Therefore, a physical fiber Identification method suitable to middle school students was developed in actual classrooms and the effects were analyzed. As a result, the physical fiber identification method was developed to distinguish between wool and acrylic knits; moreover, the identification method between silk and polyester fiber was studied. And then the inquiry sheet using fiber identification method was also developed. When interests in learning, attitudes of acceptance toward learning, and learning achievements of the experimental group (used the inquiry sheet) and the control group (did not use the inquiry sheet) were compared, the experimental group scored higher in every category, all of which were meaningful differences. Thus, this study demonstrated that the developed fiber differentiation method and inquiry sheet improved self-directed learning as well as learners' understanding of clothing materials by enabling the application the knowledge to the learners' realities.

이 연구는 고등학교 지구과학 탐구활동에서 소그룹활동을 학생들의 대화를 중심으로 분석하고, 반성적 탐구활동이 교육과정별로 어떤 차이를 보이고 소그룹내의 상호작용특성에 따라 반성적 탐구양식의 차이가 어떠한지 알아보는 것이다. 그럼으로써 학생들이 어떤 반성적 탐구양식을 보이며 어떻게 발달시키는지에 관한 이해를 제공하고, 수업속의 맥락은 이러한 반성적 탐구학습을 증진시키고 억압하기위해서 어떻게 상호작용 하는지를 알아보고자 하였다. 이에 대한 연구문제로 소그룹을 이용한 탐구활동 수업과 반성적 탐구활동수업 중 반성적 에피소드의 차이가 있는가, 소그룹내의 그룹상호작용의 특징에 따른 반성적 탐구유형의 차이는 있는가를 설정하였다. 이를 위해 고등학교 1학년 2개 학급을 선정 기존의 우리나라 교육과정에 의거한 탐구활동수업 4차시, 반성적 탐구교육과정 수업 4차시를 각각 실시하고 수업을 녹화 전사해서 언어행동 분석틀과 반성적 탐구의 3가지 맥락을 통해 분석하였다. 연구 결과 두 교육과정 모두 도입에서 두 교육과정 모두 A-AD맥락의 반성적 탐구가 전형적으로 자주 나타나며, 반성적 탐구 교육과정수업에서는 AD-SR가 주로 나오는 것으로 보아 과제활동초기에 역할 분담과 과제 활동의 전략을 세우며, 전략을 세울 때 영역개념을 이용하는 것을 안수 있었다. 우리나라 교육과정 수업에서는 반성적 탐구진술이 간단하고 계획과정이 짧으며, 주로 과제 맥락 내에서 반성적 탐구를 하는 것으로 나타났다. 전개부분에서는 두 교육과정모두 DI-DP, DI-A맥락의 반성적 탐구가 나타나 자료 항목과 자료 패턴 그리고 인공물과 관련시키는 반성적 탐구가 공통적으로 나타나며 반성적 교육과정수업에서는 대체로 자료 맥락의 영역개념과 과제 맥락을 연결시키는 반성적 탐구가 잘 나타나고 있다. 반면 우리나라 교육과정에서 주로 과제 맥락 내에서 반성적 탐구가 나타났다. 정리단계에서는 반성적 교육과정 수업에서는 DC-DP가 주로 나타났으며 우리나라 교육과정수업에서는 DC-DP DP-AD맥락의 반성적 탐구가 나타났다. 정리활동에서 우리나라 교육과정은 반성적 교육과정보다 자료 맥락의 영역개념을 더 자주 이용하고 다양한 맥락의 반성적 탐구가 나오고 있으며, 이는 우리나라 교육과정의 학습지의 활동이나 문제는 학생들에게 익숙하고, 자료 패턴을 가지고 행동결정으로 연결짓는 활동이 명확히 제시되었기 때문이라고 판단된다. 두 그룹의 상호작용 특징에 따른 반성적 탐구의 성향의 차이는 도입단계에서 그룹의 특징과 상관없이 A-AD, AD-SR맥락의 반성적 탐구가 나왔으며 전개와 정리단계에서는 N그룹에서는 DP와 관련된 의미 있는 반성적 탐구가 나오는 반면 M그룹에서는 이러한 맥락의 반성적 탐구는 아주 드물게 나타나며, GN과 관련된 행동결정이 자주 보이고 있었다. 정리활동시 주로 하는 기록 활동에서 N그룹에서는 다양한 맥락에서 반성적 탐구를 하고 있는 것에 비해 비교 그룹에서는 서로 견제하고 확인하는 상호작용의 특징에서 나타나는 AD-SR맥락의 반성적 탐구가 자주 나타났다. 반성적 탐구 척도 두 그룹을 비교 했을 때 CON 상호작용의 특징이 낮게 나타나는 N그룹이 양적으로 그리고 내용적으로 더 의미 있는 반성적 탐구를 했다
