This pilot teaching unit is one of a series developed for use in elementary school science programs. This unit is designed to help children discover specific concepts which relate to sound, such as volume, pitch, and echo. The student activities employ important scientific processes, such as observation, communication, inference, classification,…

The study investigated the effects of attentional deficits on the relative preferences for associative, acoustic, and orthographic attributes in word recognition by 45 learning disabled children in grades 2, 4, and 6. (Author/PHR)

A building shell at Southern Illinois University has partitions that can be repositioned to suit changing needs. Silencing, heating, and cooling equipment received close attention to eliminate noise. The University of Minnesota has a new underground building housing a bookstore and offices that does not require heating. (Author/MLF)

Introduces an experiment exhibiting blue and yellow-orange coloration in the plane of vibration of a vibrating string. Provides pictures and the experimental set-up. (YP)

Describes an investigation of the phonetic characteristics of children's second language acquisition, focusing on acoustical correlates of the voicing contrast for stop consonants, as produced by young native speakers of Arabic who were learning English as a second language. Neither age nor experience with English could predict phonetic…

Both existing and new English school premises are required by law to comply with minimum construction standards published by the Department for Education and Employment. This building bulletin provides practical guidance on meeting these standards covering acoustics, lighting, heating and thermal performance, ventilation, water supplies, and…

Some educational professionals have suggested that so-called green schools would result in superior performance and increased health for students and teachers. While there is no commonly accepted definition of a green school, there are a number of attributes that such schools appear to have: low cost operations, security, healthy and comfortable,…

Describes a science unit on hearing impairment which combines scientific concepts related to sound while demystifying deafness. Topics include lipreading (and what it shows), frequency/pitch, intensity, hearing aids, and audiograms. The unit is valuable whether or not a hearing-impaired child is about to enter the classroom.

Reviews research on prosody and segmental perception, segmentation and invariance, categorical perception of speech and nonspeech, feature detectors, scaling speech sounds to an auditory-articulatory space, acoustic-phonetic dependencies within the syllable, higher order (nonphonetic) factors in the comprehension of fluent speech, and cerebral…

This article is the last of a three-part series dealing with sound measurement, effects, pollution, and indoor/door learning activities. This section focuses on outdoor activities and equipment that students can make to assist them in data collection. (Author/SA)

Examines the relationship between phonetic substitution patterns in child speech and sound change patterns in dialects of adult language, basing an explanation of these phenomena on acoustic data and language universals. (AM)

Discusses the meaning and importance of sound as evidenced in film and music, and outlines the relevance of sound for cognitive and social development and personal growth. Suggests that teachers enable students to explore the meaning of sound by creating their own multimedia projects. (AEF)

This article examines the needs of students with minimal hearing loss (MHL) and offers practical suggestions to teachers. It considers legal requirements, reasons for under identification of children with MHL, signs of MHL, effects of MHL, classroom factors affecting MHL, minimizing background noise and improving listening conditions, and…

Discussed are medical applications of ultrasound. The physics of the wave nature of ultrasound including its propagation and production, return by the body, spatial and contrast resolution, attenuation, image formation using pulsed echo ultrasound techniques, measurement of velocity and duplex scanning are described. (YP)

Described are the purposes, laboratory set-ups, and procedures of four classroom experiments: ultrasound speedometer; vibrating-bar depth gauge; folding three-dimensional model of equipotential surfaces; and a simple optical system for the reconstruction of images from computer-generated holograms. Diagrams and pictures are provided. (YP)
