This study aims to provide a cornerstone for 'Pedagogical Discourse Analysis' by connecting linguistic theory to science education practice. Pedagogical Discourse Analysis (PDA) focuses its attention on finding educational implications beyond description on classroom language. This study is specially aimed at PDA in terms of the textual aspect, which has not sparked interest in science classroom discourse. For this, we supposed that the framework of PDA composed of two axes: 'thematic flow' and 'information flow'. We presented a case of science classroom discourse in terms of PDA to investigate opportunities in its potential and utilities. This trial crosses the line of traditional science classroom discourse analysis, which has been inclined to linguistics theory. It will also suggest a new horizon for science classroom discourse in an educational context.

In the elementary science classroom, inquiry-based learning activities are often limited to students' hands-on experiences. As a result, students often overlook core concepts they are supposed to acquire from the inquiry activities and show difficulties in applying those concepts in a real life context. To make a connection between the hands-on activities and the concept leaning, a small-group discussion can be considered. In this study, we designed a team-based learning (TBL) model for the elementary science classroom. We developed teaching and learning materials for the "Comfortable Environments" unit in the 6th grade curriculum based on the TBL model. After appling the model with 32 6th grade students, we compared the TBL participants' level of concept understanding and attitudes toward science before and after the intervention, and also compared them with their counterpart control group who participated in a traditional classroom. The results showed that the level of concept understanding of the TBL participants were higher than that of the control group. However, there was no statistically significant difference found in attitudes toward science between the TBL participants and the control group. In addition, the interviews with the TBL participants showed that they positively perceived the TBL experiences.

This paper seeks to find out the policies of management and layout of middle school rooms for the community people's use. This paper surveys community's needs with respect to both the use of school rooms before, during, and after classes and preferences of use of school rooms. This paper adopts two experimental case studies to find out the models. It uses t-test analysis of the statistics to find out community people's preferences for the use of school rooms between two communities in an urban area, and uses simple and multiple regression analyses to develop models concerning community people's uses of school rooms before, during, and after classes. It also uses cluster analysis to find out the cluster among community people's preference of school rooms. It found, first, that community people's use of school rooms after class can be influenced by the uses of a play ground, a music classroom, an audio visual classroom, and a gymnasium. The use during regular classes is related to the uses of the fine arts classroom, a general classroom, a home economics classroom, a gymnasium, and a playground. The use before class is affected by the uses of a fine arts classroom, a playground, and a library. It also found that, with respect to community people's preferential use of school rooms, the rooms can be clustered as a cluster of laboratories such as a general classroom, a music room, a fine arts classroom, a science classroom, a home economics classroom, and a technique classroom, a cluster of athletic areas such as a gymnasium and a playground, and a cluster of supporting facilities such as a library, an audio visual classroom, and a computer classroom. Those clusters can also be clustered in more detail, i. e., that both a general classroom and playground can be apart from a cluster of laboratories or a cluster of supporting facilities; that an audio visual classroom can be fostered into a cluster with a home economics affairs classroom and a technique classroom. Finally this paper suggests policies of management and layout of school rooms.

This study investigated the effect of subject classroom system by examining students' perceptions of science discretion class, which was newly developed as Science Mathematics specialized subject classroom system. Science discretion subject proceeded through inquiry experiments in the subject classroom, applying both block scheduling and divided classes. Surveys were conducted twice in order to find out what the students thought about science discretion subject and subject classroom class. The results have shown that students considered that the teachers have prepared with enhanced enthusiasm and the classes have become more interesting. The satisfaction level for experiment centered subject was very high (84%) and significantly higher in case of science-oriented course students (p<.05) and upper level students (p<.01). In addition, most of the students thought favorably about block scheduling and divided classes.

Heating and air conditioning system is changing rapidly from the traditional HVAC central supply system to the individual supply system with electrical heat pump system (EHP) in Korean school buildings. The individual supply system has advantages to turn on and off individually and to adjust the thermal comfort separately, but energy is wasted in the unoccupied classroom when the last leaving occupant does not turn off the controller. If the controller is to be off automatically while the classroom is not in use, energy consumption would decrease dramatically. This project aims to cease the unnecessary EHP supply in vacant classroom by inputting the class schedule from the central control room to reduce the energy-spending. Experimental measurements were carried out between the controlled classroom that is turned off when not in use and the uncontrolled room that is turned on continually. Occupant's comfort and energy consumption were measured and compared between the controlled case and the uncontrolled case. The energy consumption of controlled classroom case is 30-60% less than that of the uncontrolled classroom case. This result shows that controlling the cooling supply for the unoccupied classroom using the class schedule can decrease the energy consumption remarkably. This supply control system can be used to conserve energy in school structures like universities.

In the study, the effect of flipped classroom approach applied to chemistry I class in a foreign language high school was explored. Flipped classroom was applied to 176 grade 10 students (43 boys and 133 girls) from a foreign language high school located in a metropolitan city for one semester and its instructional effects were studied in terms of cognitive and affective aspects. Before the class, students were provided with guiding worksheets and asked to summarize contents. Within the class, various student-centered activities were adopted. After the flipped classroom for one semester, mid-term and final-term exam scores were analyzed, and students' attitude toward chemistry class and flipped classroom were surveyed. Analysis on the exam scores showed the possibility for positive impact on students' achievement and perceptions on chemistry class including flipped classroom approach. Moreover, some students mentioned flipped classroom was helpful for self-directed learning and meta-cognition. Based on these results, educational implications were discussed.

Inspired by the idea that classroom instruction proceeds through knowledge-sharing, this study examined different modes of knowledge-sharing that were realized in discursive practices in Korean secondary science classrooms. Data came from 9 science teachers. An interpretative strategy was employed to analyze the video-recording of the teachers' own science classrooms and transcriptions. The results showed four different modes of knowledge-sharing, including 'retrieving subject matter knowledge', 'reformulating subject matter knowledge', 'expansion and elaboration of understanding', and 'negotiation of meaning'. It was also revealed that there was a tie between an active mode of knowledge-sharing and scaffolding: the former allowed students to take active roles in discourses and the latter was one of the desired patterns of classroom interaction. It was suggested that further studies should be conducted to understand science instruction from more varied perspectives and to examine and utilize the detailed features of desired classroom practices like scaffolding.

Recently classroom monitoring is becoming important since the lecture is being held in the classroom and academic institutions are interested in the quality assurance. Some institutions have adopted ISO 9000 systems and constructed monitoring system through measurement, analysis and improvement. In this study quality assurance problems in academic institutions and the requirements of ISO 9001:2000 will be briefly discussed. Next we will investigate how to monitor the lecture in the classroom(in-class) using statistical process control techniques such as control charts. Then case study will be given to illustrate the technique to use appropriate statistics. Finally how to monitor the learning process during in-class and after-class will be proposed.

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.
