This study explored how teachers and students in different countries discursively interact to build 'Classroom Science Knowledge' (CSK) - the knowledge generated situatedly in the context of the science classroom. Data came from publicly released $8^{th}$ grade science classroom videos of five nations who participated in the Third TIMSS (Trend in International Mathematics and Science Study) video study. A total of ten video-recorded science lessons and their verbatim transcripts were selected and analyzed using a framework developed by the researchers of the study. It was revealed that a range of discourse modes were utilized and these modes were often sequentially connected to build CSK in the science classrooms. Although dominant discourse modes and their sequences varied among different lessons or different countries, the study identified three salient patterns of science classroom discourse: teacher-guided negotiation and the sequences of exploring - building on the shared and retrieving - elaborating. These patterns were found to be different from the discursive features commonly witnessed in the community of professional scientists and interpreted as implying the existence of unique epistemic cultures shared in science classrooms of different countries. Further studies are suggested to reveal detailed characteristics of these epistemic cultures of science classrooms, as well as to confirm whether any cultural traits inherently shape the differences in science classroom discourse among different nations.

Science-related attitudes, perceptions of science classroom environments, and their relationships were investigated for a sample of 535 primary and secondary school students. Two scales of the Test of Science-Related Attitudes and five scales of the Classroom Environment Scale(CES) were administered. Students' perceptions of preferred science classroom environments were also investigated using the same scales of the CES and compared with those of actual classroom environments. The results indicated the primary school students had the most positive attitudes on Enjoyment of Science Lesson and Career Interest in Science. They also had the highest scores on perceptions of actual classroom environments, while the high school students had the lowest scores. Regarding the relationships between science-related attitudes and perceptions of classroom environments, multiple correlations for the five scales of the CES were found to be significant(p<01). The scores of four scales-Involvement, Teacher Support, Order and Organization, Rule Clarity-are significantly correlated with the scores of Enjoyment of Science Lesson. Students' perceptions of preferred classroom environments on the four scales of the CES are significantly higher than those in actual environments. However, students' perceptions of actual environments on Task Orientation are similar to those of preferred environments, and are not significantly correlated with Enjoyment of Science Lesson. Educational implications are discussed.

The purposes of this study are to investigate elementary students' perception of science classroom through an analysis of students' answer to an open-ended question and to suggest a framework for the analysis of science classroom culture, as the first step to develop an analysis tool for qualitative exploration of science classroom culture. We analyzed 571 responses and developed an analysis framework with six categories (i.e. major factors; power structure of a classroom community; focused domains of the science classroom; student concerns; atmosphere of science classroom; participation form). The details of the six categories can be summarized as follows: (1) major factors were revealed to be practical work, fun, teacher, community and others; (2) the power structure of classroom community was in the order of peer students, teacher, and individual student himself/herself; (3) the focused domains of the science classroom perceived by students were more about affective and behavioral domains than cognitive one; (4) major student concerns were teachers' teaching, having practical work, and the understanding of and the sharing of knowledge and opinions (5) science classroom atmosphere was noisy and pranky but fun and interesting; (6) the students participation forms were to be total participation or voluntary participation or cooperative practice. Through this study, not only suggesting the framework, but we could also get implications for the cultural aspects of science classroom based on the results of data analysis in this study.

After pre-service teachers become teachers, traditional patterns of classroom discourse which they had experienced as students affect their classroom discourse implicitly. For this reason, it is needed to get a new insight for evaluating and reflecting a teacher's classroom discourse. In this study, I analyzed the information flow of science classes of pre-service elementary school teachers. The finding showed that teachers' organizational skills for students' information made advanced science classes by maintaining discourse cohesions. And the findings also showed a way how to analyze, evaluate or reflect science classroom discourse. This trial could contribute to find out the characteristics of teachers' science classroom discourse and show the directions to them how to change their classes beyond impressionable evaluations for their science classes.

This study aims to investigate the indoor air quality by analyzing $PM_{10}$ concentration and metallic elements collected from high school(classroom, science room, assembly room). $PM_{10}$ concentration of a classroom, a science room, and an assembly hall during the research period was 87.7 ${\mu}g/m^3$, $75.3{\mu}g/m^3$, $64.6{\mu}g/m^3$, respectively. Si of $PM_{10}$ had highest concentration with 15,427 $ng/m^3$ followed by Na which had 7,205 $ng/m^3$, and the order was Si>Na>Ca>Mg>Fe>K in the classroom. $PM_{10}$ concentration of a classroom and a science room was each 104.8 ${\mu}g/m^3$ and 75.3 ${\mu}g/m^3$ during the semester and $PM_{10}$ concentration of a classroom and an assembly hall was each 80.9 ${\mu}g/m^3$ and 64.6 ${\mu}g/m^3$ during the summer vacation. Based on $PM_{10}$ and metallic concentration at a classroom on day of week, the concentration of Friday was highest with 112.0 ${\mu}g/m^3$, and that of Monday was lowest with 65.3 ${\mu}g/m^3$.

This study, based on literature review and theoretical discussion, reinterprets the learning environment instruments from cultural perspectives and suggests the applicability of learning environment instruments for understanding science classroom cultures. To do this, the existing learning environment instruments are first investigated and compared in terms of their features and utilizations appeared in previous studies. The learning environment instruments are then reinterpreted in the light of culture. Finally, we suggest the possibilities to use the learning environment instruments to understand science classroom cultures. The results of this study can be summarized as follows. First, the learning environment instruments, by interpreting them culturally, could be interpreted in cultural ways and used as the alternative ways to explore science classroom cultures. Second, the learning environment instruments, such as WIHIC and CLEQ, could be interpreted both along the dimension of phenomena in classrooms and the dimension of students' psychology in order to investigate science classroom cultures. Third, the instrument items could be interpreted culturally in different ways according to the description types of instrument items. Thus, when learning environment instruments are used in culture research, the description types should be sufficiently taken into account. Based on the results of this study, educational implications are discussed in terms of exploring classroom cultures and of culture research.

This case study exemplifies science classroom observation and analysis. Data from two-day classroom observation, pre- and post-instruction interviews with the teacher and instructional materials were used to analyse the features of a science classroom. A teacher's classroom practices were examined in terms of the following six categories: (1)curriculum and science content, (2)teaching and learning methods, (3) teacher' s knowledge about learners, (4)classroom environment, (5)assessment, and (6)teacher's efforts for professional development. The teacher in this case study not only improved his own classroom practices, but also took an active role in teachers' in-service education to share his practical knowledge with others. Implications that valid evaluation(or observation) frameworks of classroom practices have on teacher education and teachers' inservice education are also discussed. These evaluation frameworks should provide teachers with a vision of highly accomplished practices.

In order to study the effect of the 'General Science' course implemented under the 6th science curriculum, high school students' views about the relationship between science/technology and society and their perceptions of science classroom environment were investigated. Four classes (n = 211) were selected from those completed the 'Science I' course under the 5th science curriculum, and 4 another classes (n = 216) which took the 'General Science' course under the 6th science curriculum were selected. In order to compare students' views about the relationship between science /technology and society. 10 items were selected from the VOSTS (Views On Science-Technology-Society) while considering the 6th science curriculum and the 'General Science' textbooks, and administered at the end of the 'Science I' course and at the beginning and end of the 'General Science' course. In order to compare the perceptions of science classroom environment, the Perceptions of Science Classroom Environment Questionnaire, which was prepared from the Individualized Classroom Environment Questionnaire. the Science Laboratory Environment Inventory, and the Classroom Environment Scale. was also administered at the end of the 'Science I' course and the 'General Science' course. The results indicated that the mean VOSTS score of the 6th-curriculum group was lower than that of the 5th-curriculum group, although the difference was not statistically significant. The decrease in the VOSTS score of the 6th-curriculum group during the 'General Science' course was statistically significant. It was also found that unrealistic views such as 'technology is the application of science', and 'corporations should control science/technology' had been formed during the course. However, the 6th-curriculum group had more positive perceptions of science classroom environment. Educational implications are discussed.

This paper presents a case study of the student's culture as a component of conceptual ecology that affects discussions and discourses in the science classroom. The present study was conducted using a naturalistic approach, mainly through observing a science class of a middle school in Seoul, Korea, and through semistructured interviews. The case showed that the science classroom culture can be identified in four aspects: (1) knowledge; (2) the teacher; (3) classmates; and (4) self. These cultural aspects were strongly related to each other and functioned as constraints in discussions and discourses of the science classroom. For successful discussions and discourses, it is necessary to consider students' cultural aspects: epistemological views on knowledge, the teacher-student and student-student relationships, and the role of self in the discussions and discourses.
