The likelihood of teaching a student with autism spectrum disorder (ASD) has steadily increased over the past two decades. However, the practical information about working with students with ASD has not increased at a similar rate. Teachers may therefore be unaware of simple modifications they can make to their classrooms to meet the needs of…

Daylighting, a controlled architectural tool that influences users' perception and behavior, in university libraries and their influences on users' preference and satisfaction was examined in this study. The effects of daylighting in coordination with visual comfort, on university library users were measured in relation to four environmental…

We describe the use of acrylic tanks (400 x 450 x 27 mm) for visualization of chemical demonstrations in aqueous solutions. Examples of well-suited demonstrations are oscillating reactions, pH indicators, photochemical reduction of Lauth's violet, and chemoluminiscent reactions. (Contains 1 figure.)

Details the dramatic changes in school lighting. Describes how lighting will be more closely integrated into the "smart" school building of tomorrow and how lighting systems will evolve with schools as technology changes. Claims that direct/indirect lighting systems will serve computer users as well as reduce energy and maintenance costs. (RJM)

Imaging of artwork is an important aspect of art conservation, technical art history, and art authentication. Many forms of near-infrared (NIR) imaging are used by conservators, archaeologists, forensic scientists, and technical art historians to examine the underdrawings of paintings, to detect damages and restorations, to enhance faded or…

Poor lighting conditions in classrooms result not only from low intensity light but also from too high intensity light, an uneven distribution of light, and glare. Since visual tasks in a classroom constitute 62 percent of a student's time in school, suggestions are made of ways lighting conditions can be improved. The principles and…

The same form of lighting will not be effective in all areas of a school facility. Factors to be considered include physical and psychological effects, visual requirements, and cost. A chart illustrates type of lamp, output/energy ratio, light "quality," and applications. (MLF)

Provides information to identify and implement the key characteristics which contribute to an efficient and comfortable visual display unit (VDU) lighting installation. Areas addressed include VDU lighting requirements, glare, lighting controls, VDU environment, lighting retrofit, optical filters, and lighting recommendations. A checklist to…

Discusses how modern schools require specific lighting systems to accommodate computers and other technologies. Describes special needs for direct and indirect lighting when considering visual display terminals and projectors, and the kind of lighting system best suited for distance learning. Offers ideas on classrooms' physical layout. (RJM)

The sources and characteristics (light measurement, direct and indirect or reflected glare) of glare problems in the video display terminal work environment are described. Glare control measures, including the location and design of lighting systems, managing outdoor light and using screen filters and hoods, are reviewed. Five sources are given.…

Guidelines for planning the lighting facilities for recreational and other athletic fields are presented (a softball field is used for an example). Guidelines are given for determining (1) lighting needs and levels of uniformity; (2) lamp choice; (3) structural requirements; (4) operating and maintenance costs; and (5) financing options. (PP)

Discusses educational facility lighting management, and examines how light quantity, distribution, and quality-enhancement strategies can improve the indoor environment while reducing lighting costs. Informational tables provide lighting pattern, color, and illuminance data. (GR)

The perception of 2nd-order, texture-contrast-defined motion was studied for apparent-motion stimuli composed of a pair of spatially displaced, simultaneously visible checkerboards. It was found that background-relative, counter-changing contrast provided the informational basis for the perception of 2nd-order apparent motion; motion began where…

Energy-efficient school lighting systems are outlined along with lighting options needing consideration when placing computers in classrooms and offices. (MD)

The New York State Lighting Efficiency Standards for existing public buildings were developed so that nontechnical persons can calculate present power used for lighting in various spaces of their buildings and then determine the recommended allowable power budget for lighting each space. (Author)
