The purpose of this study was to investigate the impact of student assessment activities on claim and evidence formation in argument-based inquiry (ABI) for high school students. The participants of the study were 166 grade 10 students from six different classes in the same high school. The experimental group (84 students) was taught Argument-Based Inquiry with students' self and peer assessment activities. The comparative group (82 students) was taught without the activities. Over one semester students participated in five ABI programs that we developed. According to the analysis of the claim and evidence from groups, the experimental group had a significantly higher mean score than the comparative group. The result of analysis of students' assessment in the experimental group, the frequency about accurate and sufficient evidence revealed to be high and students assessed whether peers' claims fit with the evidence and whether peers' explanations of the evidence's validity was sufficient. Students' answers in the survey and interviews showed that the students though they could improve the accuracy of their ideas, appropriateness of their evidence, and the method of presenting evidence based on the assessment results.

The purpose of this study is to investigate science teachers' orientation toward scientific inquiry-based teaching. In this study, five middle school science teachers formed and participated in a teacher learning community for scientific inquiry-based instruction during one year. Data collection consisted of pre and post questionnaire and interviews, audio-recordings of teachers' collaborative lesson planning and reflection on teaching practice, and field notes of participant teachers' teaching practice and follow-up interviews. Data analysis indicated that there were four orientations toward scientific inquiry-based teaching. They were knowledge and beliefs about 'goals of scientific inquiry-based teaching', 'scientific inquiry-based teaching and learning', 'argumentation-based teaching and learning', and 'nature of science and science inquiry'. Teachers' collaboration in a teacher learning community would be effective in facilitating teachers' orientation to scientific inquiry-based teaching.

The purposes of this study are to develop a measuring instrument for perception of science classes based on the view of 'Community of Inquiry in Science Classroom' and to investigate elementary school students' perceptions with the instrument developed in the study. A total of 417 6th grade students participated in this study. As a result, first, we developed two set of questionnaire: (a) the questionnaire for the 'process of inquiry' consisted of six factors: 'problem recognition I: recognition of inconsistency,' 'problem recognition II: interests,' 'problem explanation I: hypothesis generation and examination,' 'problem explanation II: cooperative review,' 'problem solving I: reflection on the change of relationship with objects/conceptions,' and 'problem solving II: reflection on the change of relationship with community/ inquirer,' comprising a total of 42 items; (b) the questionnaire for the 'basis of inquiry' consisted of three factors:'will of conducting inquiry,' 'attitudes of conducting inquiry,' and 'structure of communication,' comprising a total of 17 items. Second, we found that elementary school students had positive recognition generally on their science classes in terms of the 'community of inquiry in science classroom,' but they had relatively negative recognition on the factors of problem recognition based on recognition of inconsistency, problem solving accompanied with reflection on the change of relationship with objects/conceptions, and attitudes of conducting inquiry based on severity and fallibilism, Finally, several suggestions for the science education were given.

The purpose of this study was to investigate beginning science teachers' perceptions of inquiry-based science instruction using open-ended questionnaire and semi-structured interview. Participants of this study voluntarily set up a goal of inquiry-based science instruction, planned inquiry-based science lessons, and shared and reflected their teaching experiences in their professional learning community for more than a year. Participant teachers recognized students' construction of core scientific concepts through performing scientific inquiry as a goal of science inquiry instruction. Participant teachers indicated that goals of science education such as 'learning scientific core concepts', 'improving students' interest of science', 'improving scientific thinking', and 'understanding the nature of science' can be achieved through students' active engagement in scientific inquiry. Participant teachers recognized not only the importance of teachers' role, but also what roles science teachers should play in order to enable students to perform scientific inquiry. Participant teachers emphasized teachers' roles such as 'identifying core concepts', 'reorganizing science curriculum', 'considering student ability', 'asking questions and providing feedbacks to students', 'explaining scientific concepts', and 'leading students' argumentation.'

The purpose of this study was to examine the effects of argument structure on students' writing in implementation of argument-based inquiry using the Science Writing Heuristic (SWH) approach. Participants of this study were 108 8th grade students (three classes). Two classes (68 students) were assigned to an experimental group, and the other class (35 students) was assigned to a comparative group. The experimental group was taught argument-based inquiry using the Science Writing Heuristic (SWH) approach, while the comparative group was taught with the traditional teaching strategy. After implementing this program, the two groups were asked to write summaries using structured argumentation in their writing. The result of this study showed that the experimental group used better argument structure and multimodal representation such as pictures, graphs and examples in evidence than the comparative group. The quality of evidence used in the students' writing was different between two groups. Students of the comparative group only listed fragments of science concepts for evidence to support their claims, but students of the experimental group explained science concepts by giving specific examples. The findings show that argument-based inquiry using the SWH approach was effective on argument structure in students' writing.

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.

This research analyzed mathematical discourse of the students in an RME-based differential equations course at a university in order to investigate the social transformation of the students' conceptual model of differential equations. The analysis focused on the change in the students' use of conceptual metaphor for differential equations and pedagogical factors promoting the change. The analysis shows that discrete and quantitative conceptual model was prevalent in the beginning of the semester However, continuous and qualitative conceptual model emerged through the negotiation of mathematical meaning based on the inquiry of context problems. The participation in the project class has a positive impact on the extension of the students' conceptual model of differential equations and increases the fluency of the students' problem solving in differential equations. Moreover, this paper provides a discussion to identify the pedagogical factors Involved with the transformation of the students' conceptual model. The discussion highlights the sociocultural aspect of teaching and learning of mathematics and provides implications to improve teaching of mathematics in school.

This study is to design, develope, and deploy of e-learning inquiry based content in elementary science class. First, this study analyzed related literature review, case studies, and inquiry based class models for seeking better applicable design and development modes. From focus group meeting, experts discussed the inquiry content design ideas for elementary students for science class. This study finally established its own inquiry design mode for online science class with the flow of understanding of problem, sep up hypothesis, problem solving, and solution analysis. The developed content was deployed in real classroom setting to see how students received the contents and how well they processed the learning activities. We found that inquiry based online content, especially when applied to science subject, can be effective in students interests and their motivations. We also observed that there were a few managerial errors such as detailed lesson guidance and tutor support for students activities. This study concluded that inquiry based online contents should be designed considering students interests based on learning subjects and also developed in terms of students interests and strong motivation as well. We suggest that related research should be expanded toward to other subject than science and various students age groups.

The purpose of this research is to investigate ways to introduce mentoring system to support beginning and experienced teachers for their professional development. As an alternative to existing teacher training programs, we planned and implemented a mentoring system to examine its effects in developing professionalism among teachers-in-need, and those who have not met the teacher's evaluation standards. Mentoring is defined as being concerned with promoting the 'development of an individual to his/her full potential,' both professionally and personally. It is linked with professional and career development, and is somewhat characterized by an 'expert-novice' relationship. The mentoring system in science features group mentoring, where 3 prot$\'{e}$g$\'{e}$-mentor teams gathered together for instructional consulting using their videotaped classroom teaching. Through video-based discussions, teachers could share reflective experiences through collaborative investigations based on evidences revealed in classroom teaching videos. Using open-ended interviews with the teachers and video-based discussions, we extracted needs and goals of mentoring, the need of mentoring system to support beginning teachers, and the requirement of mentor quality in light of mentor's expected roles. Conclusions and recommendations related to teachers' mentoring and for the government's development of mentoring system are discussed.

The crisis of the COVID-19 pandemic has caused significant changes in education systems worldwide, including in Korea. Due to COVID-19's social distancing policies, the education system was suddenly switched to distance learning, resulting in many problems in primary schools without preparation. The purpose of this study was to investigate a teacher's awareness of science education techniques, responses to issues in science classes, including inquiry activities, advantages and disadvantages, and roles after experiencing distance learning. Survey and focus interviews were conducted for primary school teachers who had previously participated in distance learning, such as online content classes and real-time interactive classes. The study findings showed three conclusions: 1) Primary school teachers conducted one-way and interactive lectures in online classes. It is vital to improve a teacher's digital literacy to improve other teaching methods such as investigation and discussion in online classes. 2) Primary school teachers acknowledged the challenges of field feedback, inquiry item preparations, and safety in inquiry activities of science classes, by providing individual experimental packages and videos and using online discussion and feedback among teacher - student and student - student interactions. 3) Primary school teachers recognized that various types of classes using IT devices and individualized learning were possible as advantages of distance learning. As for disadvantages, it was acknowledged that inquiry activities, cooperative learning, immediate feedback, and interaction among students were challenging. Furthermore, learning gaps were wider in distance learning.
