This second article in a series about cooling classrooms by ventilation describes the equipment available to help save energy and money. The first article appeared in the July 1981 issue. (Author/MLF)

Described are types of programs used for processing text (editors, print formatters, and word processors), followed by the comparison of four word-processing packages: Auto Scribe, Electric Pencil, Magic Want and Word Star. With the exception of Auto Scribe, all programs reviewed are CP/M versions. (KC)

Describes the nineteenth century wave machines which can be found in the Smithsonian Institution, at Kenyon, and other colleges. Included is information about the apparatus, queries, and descriptions of different wave machines and how they work. Information included may inspire the reader with similar apparatus to repair it and use it again.…

The purchaser of wooden play equipment should check a variety of manufacturers before selecting a specific brand. The "Value Comparison Method" of purchasing playground equipment allows the consumer to make a valid comparison of many types of equipment. (JN)

Auditory performance of 40 5-year-old children was measured using a speech signal that simulated the amplified signal a child with hearing loss would hear. Subjects were restricted in their access to speech due to the hearing aid, the decreased sensation level (simulated hearing loss) at which they listened, and distance. (Contains references.)…

A follow-up study of an earlier report on the Wide Angle Mobility Light (WAML) was conducted to analyze the various applications of the device and its reliability. Results indicate high client satisfaction with WAML among test subjects (26 blind male veterans with night blindness, age 32 to 68). (Author/PB)

Today's modern roofs allow heat to build up in the roof membrane, eventually causing structural damage. An annual roof inspection typically costs less that 3% of roof replacement costs and can identify which areas need immediate attention. Offers suggestions for a roof-maintenance program. (MLF)

A study found that formal federally mandated equipment screening requirements are negligible in meeting their stated objectives of preventing purchase of unnecessary/duplicative equipment. Savings resulting from purchases not made represented under 0.008 percent of all federal dollars used to purchase equipment, with $10.35 spent for every dollar…

This discussion of interactive videodisc systems for students who are deaf or hard of hearing considers the advantages and disadvantages of such systems, system use, videodisc capabilities, interactive alternatives, and selecting a system for a school. A list of equipment manufacturers, laser disc producers, and specialty sources is provided. (DB)

FM (frequency modulation) classroom amplification systems are described. Advantages for students with only minimal hearing losses as well as those more seriously affected are noted. Research on FM classroom systems and input from 20 teachers support the use of this technology with students who need a slightly higher volume level of instruction.…

This article reviews current knowledge in three areas: (1) characteristics of mild/moderate hearing loss; (2) the information-bearing aspects of speech; and (3) the relationship between the electroacoustic characteristics of hearing aids and the speech signal. Implications for selecting hearing aids are drawn. (Author/DB)

This article describes devices that people with visual impairments and diabetes can use to monitor blood glucose levels and measure insulin. A table lists devices, their manufacturers (including address and telephone number), and comments about the devices. (DB)
