Discusses the design and interpretation of instrumental phonetic studies of second language (L2) speech production. The speech of L2 learners is evaluated to determine to what extent it diverges from the differing phonetic norms of L1, which are estimated from the speech of a small number of native speakers. (Author/LMO)

Presents a state-of-the-art review of acoustics and its interaction with branches of the sciences and arts. Identifies the current divisions of acoustical study as classified by the American Institute of Physics. Provides descriptive summaries of ten different countries' instructional programs in this discipline. (ML)

Discusses the effect of silhouetting a vertical vibrating string against a television screen. The article also reports the usefulness of the effect in tuning stringed instruments and as a possible basis for lecture demonstrations and student discussions and investigations. (HM)

Examines the current technological benefits and limitations of individual frequency-modulated (FM) systems for students with hearing impairments in the typical classroom setting. Recent technological advances such as diminished size and increased battery power that may alleviate current limitations are also discussed. (Author/DB)

Six major concepts of science are illustrated through the use of simple, easily equipped hands-on activities. Included in each activity are a list of materials, procedures, questions for students, and suggested discussion. Aquatic acoustics are highlighted. (CW)

A multisensory sound lab has been developed at the Model Secondary School for the Deaf (District of Columbia). A special floor allows vibrations to be felt, and a spectrum analyzer displays frequencies and harmonics visually. The lab is used for science education, auditory training, speech therapy, music and dance instruction, and relaxation…

Presents an outdoor experiment to measure the speed of sound as a classroom experience to begin the teaching year. Measures the delay time from seeing and hearing crashing cymbals across a field to calculate the speed. Exposes students to experimental uncertainties and limits of uncertainty in measurement. (MDH)

This study examined the interaction of acoustic-phonetic information with higher-level linguistic contextual information during the real-time speech perception process in child, young adult, and older adult listeners. Findings indicated that target word predictability influenced the timing and nature of the real-time recognition process, including…

A study exploring the differences between first- and second-language word recognition strategies revealed that second-language listeners used more higher level information than native language listeners, when access to higher level information was not hindered by a competence-ceiling effect, indicating that word processing strategy is a function…

Using sound field amplification which increased the intensity of the teacher's voice by 10 decibels, 9 primary-level children with developmental disabilities made fewer errors on a word identification task, were more relaxed, and responded more quickly than without amplification. (Author/JDD)

Described are four musical instruments constructed from polyvinyl chloride (PVC) pipe. The use of computerized synthesizers to play scales and chords is discussed. Suggestions for other illustrations of acoustics are included. (CW)

Examines how science teachers' (n=14) knowledge of science and science pedagogy changed after participation in a constructivist-based methods course. More-experienced teachers were paired with less-experienced teachers, and pre- and post-instructional concept maps, journals, portfolios, and transcripts revealed that, within the zone of proximal…

Analyzes changes in oral communication skills of five American adult learners who participated in a five-week study abroad program in Spanish. Subjective analysis of recordings of participants upon their return show that four participants increased their command of the vocabulary and were more at ease in discourse interaction. (14 references)…

A study investigated the efficacy of sound-field amplifications for four children (ages 5-7) with Down syndrome. Measures of speech perception were taken with and without the sound-field system and found that the children perceived significantly more speech in all conditions where the sound-field system was used. (Contains references.) (Author/CR)

This activity is the result of a school-university collaboration among four educators (two intermediate classroom teachers, a vice-principal/teacher, and a university-based teacher educator/researcher) who worked together to improve the quality of learning in the classroom. The educators combined their teaching expertise to plan and co-teach an…
