In this paper, we designed the on-line Real-time Video Communication Learning System(RVCLS) for Web-based project learning and develop programs for test groups. And we have also analyzed how the Web-based learning using RVCLS change the students' perception on the classroom environment, using the WIHIC which is the classroom environment examination tool As a result, the Web-based project learning activities using RVCLS had affirmative effects on the eight areas of classroom environment such as students unity, teacher support, participation in class, spontaneity, exploration activities, task-oriented mind, cooperative attitude, and equality. Also, the web -based project learning using RVCLS is expected to help students enhance the self-directed learning capacity and increase abilities to use ICT.

In this study, we explored students' epistemological framing during scientific argumentation and how interactions among group members influenced group argumentation. Twenty-one gifted science students divided into groups of three or four participated in this study. Students' discussions related to data interpretation concerning the rate of photosynthesis were analyzed. Students' activities were videotaped in groups so the discourse could be transcribed and students' behavioral cues analyzed. Students' epistemological framing has been identified through analysis of their speech and behavioral responses to the anomalous data from the inquiry process. Subsequently, their sources of warrant and group argumentation levels were explored. We found out that group members framed the inquiry in two ways: "understanding phenomena" and "classroom game." Group members whose framing was "understanding phenomena" required other members to justify the anomalous data by examining its validity and reliability, which conclusively demonstrated a high level of argumentation. On the other hand, when group members used "classroom game" to frame their argumentation, they did not recognize the necessity of explaining the anomalous data; rather, these students used simple empirical justification to explain the data, reflecting a low level of argumentation. When students using different epistemological framing disagreed over interpretations of anomalous data throughout the discussion, clashes ensued that resulted in emotional conflict and a lack of discussion. Students' framing shifts were observed during the discussion on which group leaders seemed to have a huge influence. This study lays the foundation for future work on establishing productive framing to prompt scientific argumentation in science classrooms.

인간의 교수${\cdot}$학습은 본질적으로 뇌 기능과 많은 관련을 맺고 있기 때문에 뇌-기반 학습에서는 우리의 뇌가 최적으로 학습하는 방식에 기초해 접근을 시도한다. 지난 30년간의 뇌에 대한 연구는 교수${\cdot}$학습에 대해서 이용할 만한 많은 정보를 제시하고 있다. 많은 교육연구가들은 뇌 연구를 기초로 뇌가 최적으로 학습하는 뇌-친화적 환경을 도입하였고, Politano & Paquin(2000)은 현행교실에 실제로 이용 가능한 뇌-기반 환경을 창조하기 위한 기초로서 10가지 요소를 제시하면서 뇌-기반 학습에서 학습자는 자신에게 익숙한 학습감각을 가지고 있으며 그것을 통한 학습이 효과적임을 말하였다. 수학교육에서도 이와 같이 뇌-기반 학습을 배경으로 하는, 학습자의 학습감각을 고려한 교수${\cdot}$학습이 의미있다고 할 수있다. 본 연구에서는 뇌기반 학습의 의미를 고찰하고, 제 7차 교육과정이 실행되는 초등학교 4학년, 중학교 2학년, 고등학교 1학년에 교실에 대한 학습감각을 조사하였으며, 수학 교실에서 학습자의 학습감각을 고려한 수업활동을 제시하였다.

Daily science classes, which have been continued as part of the spread of participatory science culture, has taken the lead in popularizing science as an effective out-of-school experiential and research activity. However, due to the recent COVID-19 situation, daily science classes have also become an environment in which there is no choice but to switch to non-face-to-face or to combine face-to-face and non-face-to-face education. Therefore, in this study, we examine how elementary school students participating in the non-face-to-face daily science class program change their usual fields of interest, perception of science and technology, interest about science, and scientific competency. In addition, the educational effectiveness of the non-face-to-face daily science class improved by comparing the differences in perceptions of students and parents, and future operation plans were sought. As a result of the study, after participating in the non-face-to-face daily science class program, students' interest in science and technology development, future technology, environmental pollution, and social media increased, and their interest in games decreased. Also, students' interest in science and technology activities, interest in science, and scientific competency also increased. This shows that non-face-to-face daily science class education is effective. Therefore, it was suggested that it is necessary to diversify the learning topics and content levels of the daily science class program, to expand the opportunities of non-face-to-face science education for underprivileged learners, and to develop and share science content using the latest media.

This study is to make strides toward an enriched understanding of changing a prevailing teacher-centered mathematics classroom culture to a student-centered culture by analyzing six reform-oriented classrooms of three elementary school teachers throughout a year This study provided a detailed description of important classroom episodes to explore how the participants in each class established a reform-oriented mathematics microculture. Despite the exemplary form of student-centered instruction, the content and qualities of the teaching practices are somewhat different in the extent to which students' ideas become the center of mathematical discourse and activity. Given the similarities in terms of general social norms and the differences in terms of socio-mathematical norms and mathematical practice, this study addresses some crucial issues on understanding the culture of elementary mathematics classroom in transition.

The purpose of this study is to analyze classroom norms formed in inquiry activities of elementary science classes and to consider about the actual problems in enacting school science inquiry. Focusing on the inquiry activity cases of two classes, the data were collected through classroom observation, student interview, teacher interview and questionnaires. Firstly, classroom norms were categorized into three categories theoretically: norms for behavior guidance; general academic norms; and scientific inquiry academic norms. The subcategory norms of each category were extracted inductively and the features, the causes of formation, and the influences on inquiry of each norm were also analyzed. Based on the analyses on classroom norms, the researchers identified three actual problems in enacting school science inquiry. First, the collective traits of school science inquiry caused structural problems in science classrooms. Second, teachers used their authorities in different ways according to phases of instructions. Third, the conflict cases were reported between general values for education and specific values for science inquiry. Educational implications are discussed in terms of the practices of school science inquiry and of the understanding classroom phenomena.
