The role of corrective feedback (CF) has long been discussed in the field of second language acquisition. It has been claimed that CF enables learners to notice the problems in their second language (L2) production. However, it should not be assumed that learners always adequately interpret teachers' responses to their problematic utterance as correction. Especially when feedback is provided in an implicit way, the possibility that CF goes unnoticed should not be excluded. In this regard, the study aims to investigate how learners perceive teachers' corrective feedback in English classrooms in Korea. The study focuses particularly on examining the relationship between type of feedback and target linguistic content with learner interpretation of teacher corrective intention. Nine classrooms were observed and videotaped. Forty-five students and nine teachers participated in stimulated recall interviews. Their comments were analyzed to document the learners' perception and the teachers' intention of feedback. It was found that learner perception of teacher corrective intention was at its greatest when feedback was provided explicitly and was focused on morphological errors.

The purpose of the study was to suggest a few fundamental ideas to secondary mathematics teachers regarding using LOGO in their classrooms. Even though this software is "classic" in mathematics lessons in the States and western countries, Korean secondary mathematics teachers did not have much opportunities to become familiar with this software and its applications in their classrooms. This article offered a few suggestions with the specific guidelines. Basic commands were also listed for those who are not familiar with this software. Since the current Korean educational curriculum do not allow to use LOGO in regular classrooms as substitute lessons, it is recommended to implement these ideas in extra curriculum lessons or "Math Club" as trial basis.

A peer assessment method was implemented as part of an action research project where the primary goal was to create constructivist science classrooms. Student reflective writings, which had been created in the process of action research, were analyzed to examine the perceptions of the students concerning the peer assessment method employed in their earth science classrooms. Five perception categories and thirteen statements were developed from the student writings. These indicated that the students appreciated the positive nature of peer assessment and the effects of it as an alternative method for promoting learning. It was also revealed, however, that some students displayed inappropriate behaviors toward peer assessment which led to negative perceptions of the new assessment method. Implications for future use of peer assessment in science classrooms are discussed. Limitations founded in the present study as well as possible solutions are provided.

This study was carried out to obtain basic data for architectural plans on the facilities relocation needed in operating the departmentalized classroom system at the latest built middle schools. For this, floor plans of ten middle schools built in Gwangju after 2009 were analyzed about space configuration and area holding state. The process of this study is as follows: (1) To investigate proper area holding state for operating variation type, this study analyzed area of departmentalized classrooms, homebases and teachers' offices. (2) To investigate space configuration for operating variation type, this study analyzed composition of departmentalized classrooms, learning-support facilities and homebases. (3) On the base of those analyses, this study proposed some directions for architectural plans on the facilities relocation.

This paper describes how communicative technology between two classrooms located in different sociocultural contexts was used to support mathematics instruction. I analyzed what interactions emerged using the communicative technology, how sociocultural differences were leveraged to construct mathematical knowledge, and how students built this knowledge together across urban and rural classrooms. The results show that reciprocal interactions emerged. Teachers co-designed lesson plans and tasks with consideration of the different classroom social contexts. Based on those teachers' interactions, students had opportunities to justify their ideas and to prepare answers before the connected discussions, and a wide spectrum of ideas was synthesized as collaborative knowledge. These findings suggest that communicative technology has the potential to enhance learning opportunities for students across different social contexts.

The basic unit of school is a classroom and the aural environment of the classrooms is essential factor for education purposes. Therefore, many efforts have been undertaken for enhancing the acoustical performance of the classrooms in many countries. As a result, acoustic criteria including reverberation time and background noise level have been established in US and UK for school classrooms depending on the usage and size of the rooms. However, in Korea, there has been little researches concerning the room acoustical investigations of the classrooms. The present study investigates the current situation of the aural environment of the 15 classrooms in Korea including elementary, middle and high schools. The acoustic criteria measured include RT, $D_{50}$, STI, SNR and background noise level. As the results, it was found that the background noise levels of the schools adjacent to roads exceed the US and UK standard of 35 dB(A). Also, most schools have so low SNR that they may be interfered by noise, which may affect speech transmission. It was also revealed that some schools have longer RT than the US standard of 0.6 s, but they all have high speech intelligibility.

This study investigated differences in play types of preschool children with disabilities both in mainstreamed and segregated classrooms. The play behaviors of 50 preschool children with disabilities were observed and videotaped during free play time. Differences were found in children's dramatic and group play. Conclusions were that mainstreamed preschool program emphasizing a play-based curriculum could be an effective model for children with disabilities by providing for a variety of play types. Implications for mainstreaming education and for teacher education were discussed.

Although student-centered teaching practices have been advocated in mathematics education reform, implementing them at the classroom level remains challenging. This exploratory case study examined two unevenly successful student-centered approaches to see how teachers understand and characterize reform, and to articulate issues in implementing reform ideas. The comparison and contrast between the classrooms showed similar classroom social norms but dramatically different mathematical practices. This affords the possibility of exploring the challenges of reform for teachers and other personnel who are attempting to move teaching practices towards the student-centered ideals.

Recently, higher discussions are made up on the culture of mathematics classrooms. These discussions are mostly about desirable culture and reform of culture in mathematics education. This paper is to offer a view point of seeing the culture of mathematics classroom. We need to look straightly our classroom as well as to reform the culture of mathematice classroom. This paper recommend sociomathematical norms to analyze and reform classroom culture. A elementary mathematics classroom was analyzed to understand our own culture of mathematics classroom.
