This study is to support the school's mathematics exploration activities. Mathematics exploration is a very important mathematical activity not only for mathematics teachers, but also for students. Looking at the development of mathematics, it has been extended from one mathematical fact to a new mathematical fact. Mathematics exploration activities are not unique to mathematicians, and opportunities are equally given to all ordinary people who are learning mathematics and teaching mathematics. Therefore, the purpose of this study is to develop a method of mathematics exploration activities that teachers and students can perform in schools, based on mathematics exploration activities based on one mathematical fact. Specifically, the cosine law was selected as one mathematical fact, and mathematical exploration activities were performed based on the cosine law. By analyzing the results of these mathematics exploration activities, we developed a method to explore school mathematics. Through the results of this study, it is expected that mathematics exploration activities will be conducted equally by students and teachers in the mathematics classroom.

This study explores and conducts an in-depth comparison of the epistemic characteristics in different data types utilized in the science inquiries of preservice teachers regarding noise as a risk in everyday life. Focusing on primary and secondary data in the context of science inquiries about noise, we examined how these data types differ in science inquires in terms of inquiry design, data collection, and analyses. The findings reveal that sensor-based primary data enable direct measurement and observation of key phenomena. Conversely, secondary data rely on predetermined measurement methods within a public data system. These differences require different epistemic considerations during the inquiry process. Based on these findings, we discuss the educational implications concerning teaching approaches for science inquiries, teacher education for inquiry teaching, and the development of risk response competencies in preparation for the VUCA (Volatility, Uncertainty, Complexity, and Ambiguity) era.

정보화 사회에서는 자기 학습력 신장이 강조되고 있다. 초등사회과 교육에서 자기 학습력을 신장시키기 위해서는 다양한 학습자료의 제공을 통해 개개인의 특성에 맞게 탐구할 수 있는 탐구능력의 육성이 중요하다. 본 논문은 웹 기반 코스웨어를 개발 제작하고 이를 수업에 활용함으로써 개별학습이나 탐구학습에서 바람직한 효과를 거두는데 그 목적이 있다. 본 시스템은 단순히 텍스트와 정지된 그림만을 보여주는 기존의 웹을 활용한 학습과는 달리 Flash를 이용하여 학습자와 상호작용하여 많이 일어나도록 게임학습 위주로 구현하였으며, ASP를 이용하여 자료실, 게시판을 만들어 학습자 상호간에 적극적인 인터페이스가 이루어지도록 하였다. 연구대상은 초등학교 4학년 학생이며, 웹 기반 코스에서 활용 집단과 전통적인 방식의 학습 집단으로 구분하여 연구하였다. T검정과 분산분석을 통해 성적의 변화패턴에 차이가 있다는 것을 알 수 있었다. 이는 '문화재와 박물관' 단원을 학습하는데 있어 웹 기반 코스웨어를 활용한 학습자의 흥미와 호기심을 유발시켜 학습의욕과 교수 학습 방법을 개선하는데 기여하리라 기대되며, 전통적인 방식의 학습보다 효과적이라는 결론이다.

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.

This study focused on the use of student assessment activities to investigate the impact on reflective thinking in Argument-based Inquiry. The participants of the study were 166 10th grade students (six classes). Over one semester, students participated in five ABI programs that we developed. 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. We analyzed students' reflective writing to investigate how the student assessment activities influenced the students' reflective thinking. We also used the interviews and surveys to examine the validity of student assessment activities. According to analysis of the reflective writing, the experimental group had a significantly higher mean score than the comparative group in the 3rd and 5th writing. The ratio of students who showed a metacognitive level of reflection with regard to analysis of inquiry process, understanding of learning, and change of thinking increased in both groups, but the experimental group's ratio was higher than the comparative group's. The result of analysis of the reflective practice showed that the ratio of the experimental group's students who reached the metacognitive level of reflection in their writing increased, while the comparative group's decreased. Therefore, we conclude that student assessment activities can create a learning environment that facilitates student participation, increases the students' engagement in the learning process, and can be used as a tool to scaffold learning.

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.

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.

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.
