The present study aims to investigate the effects of sound diffusers and absorbers on the sound clarity in classrooms. In order to do this, computer simulations were carried out to find the effective area of treatment which could enhance the sound clarity in the room. Acoustic measurements were undertaken in a lecture room with several conditions changing the surface of walls and ceilings with diffusers and absorbers. Diffusion and absorption treatments were applied to the side walls, rear wall and the ceiling of the classroom. SPL, RT, D50, RASTI were measured at 9 measurement points with one sound source and MLS was used as the sound source signal. The results show that higher sound clarity was obtained when diffusers were applied to rear walls and ceiling rather than side walls. Also, it was confirmed that absorption increased sound clarity more effectively with smaller amount in comparison with diffusers. It was also concluded that the effects of sound diffusers and absorbers on the sound clarity could be obtained distinctly at the rear area of the classroom.

As Snow (1989) and Sternberg (1985) have long argued, learning, and adaptation to the learning environment or classroom context (at the levels of instructional treatment, interventionist focus on form technique, or pedagogic task) is a result of the interaction of context at each of these levels of description with learners' patterns of abilities. In this paper I argue that this is an important area of research for SLA pedagogy, as well as SLA theory development, and I review recent developments in the study of L2 learning conditions; of the abilities contributing to L2 aptitude; and of their interaction with the processes involved in successful classroom learning and practice, and propose a model of ‘multiple aptitudes’ for classroom learning based on these findings.

The aim of this study was to provide basic materials that would enable students who take courses in the subjects of technology and home economics to take the knowledge and technological skills they learn in the classroom and apply them to real life situations and to nurture their thinking power and creativity. To achieve these research objectives, a survey was conducted on 217 home economics teachers at 129 schools in the metropolitan area in order to assess their classroom operations and the adequacy of the curriculum regarding "clothes-making and reuse." The results showed that most of the schools surveyed have only one classroom for home economics and that a majority of them are cooking rooms. The most preferred place to practice making clothes was found to be the classroom. In addition, the use of teaching aids pertaining to clothes-making are lacking or in poor shape. Furthermore, analysis of the curriculum regarding "clothes-making and reuse" showed that most of the students use kits that contain materials for making clothes, due to a lack of practice hours. Most teachers thought that this section was appropriate for the school curriculum. In the more detailed categories, the students' ability to use sewing machines was the lowest, while the ability to sew by hand was selected as the most useful and most appropriate for real life situations.

The study is focused on making space of the abolished primary school for college dormitory in rural area which has regional type nearby city. We, firstly, analysed regional conditions and then surveyed various data for space conditions of dormitory. By surveying exterior space and interior renovation, and analysing the actual conditions of dormitory, we propose design factors and model of using facilities of the abolished primary school. So, the purpose of it is to suggest making space and a model of dormitory utilization of abolished school in regional type nearby city. It is a spacial case of re-using facilities of abolished school in rural area, but we expect that abolished school make an offer another type of using facilities.

The purpose of this study is to propose an appropriate criterium for proper sound insulation service preventing school classrooms from aircraft noise. The guideline of noise level for school facility by Korean school health law is less than Leq 55 which is less stringent than that of other countries. It has been reported that many students are annoyed and disturbed for their works when they are exposed to the noise level over Leq 55. It is desirable to modify this guideline of indoor noise level for school classroom. The noise level of classroom of which windows are opened was measured relatively high in case the school is located at the outside of the official area damaged by aircraft noise. In order to minimize the influence of aircraft noise on the school classrooms in the vicinity of domestic airport, it is necessary to improve the present criteria of WECPNL 75 for the establishment of the area damaged by aircraft noise from WECPNL 70.

The purpose of this study was to suggest the basement in making definite curriculum through the analysis of the curriculum and implementation of Invention Classroom in Seoul area and findings of the problems perceived by the teachers. This study analyzed the curriculums of 19 'invention classrooms' in Seoul area, asked the teachers about the problems and things to need improving through interviews and the results are following. First, it is necessary to make the more definite curriculum because there is a little big gap between the regions and the teachers in running the 'Invention Classrooms'. Second, it is necessary to narrow the gaps through the definite curriculum because the purposes, contents, teaching methods and evaluation tools perceived most importantly or emphasized most by the teachers were so different from the real suggestion in the curriculums. Third, it is necessary to suggest the definite guideline in order to overcome the regional gaps because there are a little big gap of implementation between the classes in planning teaching periods, credits needed and so on. Fourth, the teachers have perceived many problems in educational, administrational and financial aspect and so it is necessary to properly reflect them on planning the curriculum of Invention Classroom through many proper studies to improve them.

Elementary School is a special facility where sense of place plays critical role for the development of children. Children in special education call for special attention as they hold inferior status compared to the children in regular class especially under the inclusive education policy. Eight cases of special education class area are analyzed in terms of social space, personal space and favorite place which is known to be basic factor for the development. As a result outdoor space found to be designed inappropriate even when designed accessible to the special education class as it could not meet the developmental needs of children in special education. Special education class area inside the building is also found to be too exclusive to allow social mix with children in regular class disregarding the intention of inclusive education. Location of these class should be strategic as it is critical to be linked with regular classroom efficiently still allowing psychological buffer as the children in special education tend to form restorative space inside the special education classroom showing the possibility of creating sense of place there.
