Studi ini melakukan evaluasi pencahayaan alami pada ruang belajar Sekolah Dasar Negeri 2 dan 6 Banda Sakti, Lhokseumawe.  Sekolah tersebut berada pada lokasi urban padat dan merupakan sekolah dengan bangunan terluas di kecamatan Banda Sakti.  Ada 36 (tiga puluh enam) ruang kelas yang dilakukan simulasi pencahayaan alami pada objek studi ini.  Simulasi pencahayaan alami dilakukan dengan metrik useful daylight illuminance (UDI).  Metrik ini menggunakan data cuaca lokasi objek penelitian dalam hal ini data cuaca Kota Lhokseumawe dalam format energyplus weather (EPW) file.  Pemodelan untuk simulasi dilakukan dengan piranti Rhinoceros, sementara algoritma simulasi dibuat menggunakan Grasshopper dengan tambahan plugin Ladybug Tools.  Ladybug Tools memberikan akses ke engine simulasi Daysim yang merupakan perangkat simulasi pencahayaan alami yang tervalidasi.  Pada penelitian ini ketegori UDI terpenuhi dialterasi sesuai dengan standar pencahayaan alami disarankan dalam SNI 03-6197 yaitu 250-750 Lux untuk ruangan yang digunakan pada bangunan pendidikan dalam hal ini sekolah dasar.  Hasil menunjukkan tidak ada ruang kelas yang dikategorikan baik pada SDN 2 dan 6 Banda Sakti.  Hanya terdapat 29 (dua puluh sembilan) kelas dengan kategori cukup dan 7 (tujuh) ruang dengan kategori kurangUSEFUL DAYLIGHT ILLUMINANCE (UDI) IN ELEMENTARY SCHOOL CLASSROOMS IN TROPICAL HIGH DENSITY URBAN AREA (CASE STUDY: SD NEGERI 2 AND 6 BANDA SAKTI, LHOKSEUMAWE, ACEH, INDONESIA) This study evaluated the daylight distribution within classrooms at Sekolah Dasar Negeri 2 and 6 Banda Sakti, Lhokseumawe.  The school is located in high-density urban area, and it was the largest state elementary school building in Banda Sakti.  36 (thirty-six) classrooms were simulated for its daylight performance.  The simulation utilized useful daylight illuminance (UDI) metric. The metric used the local weather file for Lhokseumawe in energyplus weather (EPW) format.  Modeling for simulation utilized Rhinoceros; further, the simulation algorithm was created using Grasshopper with the extension of Ladybug Tools.  Ladybug Tools opened access to a Daysim, a validated daylight simulation engine.  In this study, the useful daylight was referenced to SNI 03-6197, which was 250-750 Lux for educational spaces at this study classrooms for the elementary school.  The result showed there was none of the classroom fallen under a good category. 29 (twenty-nine) classrooms was under insufficient category and 7 (seven) classrooms under a bad category

Daylight Performance

Refurbished heritage buildings usually lack in meeting the required standards defined for the new function especially when reused as educational buildings. Therefore, they are usually equipped with different post-occupancy retrofit strategies to achieve an acceptable level of environmental quality and energy demand. Daylight quality and the distribution of natural light is a critical issue in educational spaces, given that the low level of illuminance in classrooms can decrease students' performance and disrupt visual tasks. In this study, daylight performance of below-grade south-facing classrooms in a heritage building in Tehran, Iran is investigated by implementing 57 different daylighting retrofit strategies using climate-based daylight simulations, in relation to the metric Useful Daylight Illuminance 300-3000lux (UDI-Autonomous). The research proposes the use of reflectors on the interior ceiling and exterior side of the windows (on the ground) to achieve the highest result possible. Although, applying these two systems individually, can boost the spatial distribution of daylight to 75 % and 71%, respectively, the combination of them provide users with UDI-Autonomous in 99% of the classroom space for more than half of the occupancy time.

This paper makes a case study of an elementary school in Feng-shan District, Kaohsiung City. According to “The handbook of seismic resistant evaluation standard for school buildings” issued by National Center for Research on Earthquake Engineering (NCREE) in 2009, this study analyzes elementary school building adopting braced steel frame retrofit system, conducts seismic evaluation, as well as compares its seismic performance with shear-wall retrofit structure and RC strengthening of columns . If space permits, braced steel frame retrofit system can be applied into school building retrofit scheme; its seismic performance is compared with shear wall and RC strengthening of columns proposals. Adopting shear wall or RC strengthening of columns retrofit would affect main structure system of school building. These constructions will make existing reinforced concrete school building crack, especially old school building whose structure strength is greatly influenced. Therefore, an economic braced portal frame systems are proposed as new way of retrofitting. This paper uses ETABS program to make a seismic evaluation for structural system of the study object. It also compares the research object with commonly-used shear wall retrofit and RC strengthening of columns retrofit, thus to judge whether it meets requirements stipulated in seismic standards issued by NCREE and provide an another alternative scheme for the primary school retrofit construction.

This study aims to explore the use of video in English language teaching (ELT) elementary school (grades 8 to 9)... In addition, the thesis aims to find out how videos in English lessons helped to achieve the goals of English curriculum. The main hypothesis was that teaching with video would develop pupils’ communicative skills and, therefore, was appropriate for the communicative approach to ELT. The study addressed five research questions regarding the use of videos in English lessons in the case study school: why the teachers used videos in ELT, what kinds of videos were used in English lessons, how and how often videos were used, what was taught and learned through the use of videos and, finally, what the teachers’ and pupils’ attitudes to lessons with videos were. The research was performed as a case study at an Elbasan elementary school. The data for the research was obtained through the use of mixed methods: qualitative, in the form of interviews with four English teachers and observations of three of the interviewed teachers’ lessons with videos, and quantitative, in the form of a pupil questionnaire answered by 105 pupils from two 8th grade and two 9th grade classes.
