In addition to the linguistic diversity of South African nationals, growing number international students from other countries, especially Africa, has made language-related issues in university classrooms more complex. The teaching-learning process is very challenging with linguistically heterogeneous learners different symbols and meanings that influence way they learn could be a source exclus...

We present a scalable workload model for media-enhanced classrooms. Such classrooms include equipment for presenting multimedia streams and for capturing streams of information (audio, video and notes) during a lecture. Our model characterizes the workload of a centralized or distributed server that supports multiple classrooms. The workload includes server bandwidth, network band-width and ser...

AIM To increase the awareness of environmental risk factors by determining the indoor air quality status of primary schools. MATERIALS AND METHODS Indoor air quality parameters in 172 classrooms of 31 primary schools in Kecioren, Ankara, were examined for the purpose of assessing the levels of air pollutants (CO, CO2, SO2, NO2, and formaldehyde) within primary schools. RESULTS Schools near ...

Carbon dioxide (CO2 ) sensors that provide a visual indication were installed in classrooms during normal school operation. During 2-week periods, teachers and students were instructed to open the windows in response to the visual CO2 feedback in 1 week and open them, as they would normally do, without visual feedback, in the other week. In the heating season, two pairs of classrooms were monit...

To compare physical activity levels in adolescents with and without intellectual disabilities during physical education and recess. Forty adolescents diagnosed with intellectual disabilities (inclusive classrooms, n=20; self-contained classrooms, n=20) and 40 age-matched typically developing peers (general classrooms) participated. All participants wore an Actigraph GT1M accelerometer for 5 con...

The presence of microorganisms on common classroom contact surfaces (fomites) was determined to identify the areas most likely to become contaminated. Six elementary classrooms were divided into control and intervention groups (cleaned daily with a quaternary ammonium wipe) and tested for heterotrophic bacteria. Three classrooms were also tested for norovirus and influenza A virus. Frequently u...

Given the prevalence of computers in education today, it is critical to understand teachers’ perspectives regarding computer integration in their classrooms. The current study surveyed a random sample of a heterogeneous group of 185 elementary and 204 secondary teachers in order to provide a comprehensive summary of teacher characteristics and variables that best discriminate between teachers w...

In this study, we explored the potential of two forms of discussion (disciplinary vs. traditional) for 39 sixth- and seventh-grade students with or at risk for learning disabilities (LD), before writing historical arguments. Nine teachers who led small group discussions in six heterogeneous social studies classrooms implemented the intervention. Students who were involved in disciplinary discus...

This project seeks to determine what relationship, if any, exists between background noise levels in elementary classrooms due to the building mechanical systems and student performance on achievement tests. Previous research in classroom acoustics has clearly identified that lower background noise levels result in higher speech intelligibility which is crucial for the learning process; however...
