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.

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.

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…

According to Denehy (1999), "school nurses can play a powerful role in promoting health in their schools and community." She encouraged school nurses to "Take and make opportunities to promote health in the classroom" (p. 4). Classroom presentation of hearing conservation information is one way for school nurses to promote health and to reduce the…

As energy costs rise and resources dwindle, schools and universities can benefit greatly by taking an environmentally sensitive approach to construction, renovation and maintenance of facilities. Administrators free up needed budget resources by operating facilities more efficiently. Using sustainable-design strategies can set a good example for…

Purpose: This study compared the influence of speaker-implemented iconic hand gestures and alphabet cues on speech intelligibility scores and strategy helpfulness ratings for 3 adults with cerebral palsy and dysarthria who differed from one another in their overall motor abilities. Method: A total of 144 listeners (48 per speaker) orthographically…

This manual was developed by the Community Resource Curriculum Development Project (CRCDP), a cooperative project to develop multi-disciplinary, multi-ethnic, multi-cultural science/social sciences teaching units based upon the Illinois State Goals for Learning and Chicago public school outcomes for a seamless fifth and sixth grade cluster. This…

This paper discusses common causes of problems encountered with audio systems in distance learning networks and offers practical suggestions for correcting the problems. Problems and discussions are divided into nine categories: (1) acoustics, including reverberant classrooms leading to distorted or garbled voices, as well as one-dimensional audio…

In an effort to provide science teachers with the tables and scales most often used in teaching earth science, this document was designed to coordinate each table with meaningful activities, projects and experiments. The major areas covered by the booklet are: (1) electromagnetic waves (with activities about light waves and sound waves); (2) the…

This work treats some of the important issues encountered in an attempt to synthesize natural sounding English speech from arbitrary written text. Details of the systems that interact in producing speech are described. The principal systems dealt with are phonology (intonation), phonetics, syntax, semantics, and text-view (discourse). Technical…

Phonetic characteristics of English, German, Spanish, and French vowels are compared and contrasted in this third of a series of articles on general phonetic characteristics of American English. Much attention is given to acoustic and articulatory description. Vowel distribution, frequency, and duration are discussed. New vowel sounds for the…

This report covers research conducted between July 1972 and March 1973. Experiments were conducted on the automatic detection of constituent boundaries and location of stressed syllables by analysis of fundamental frequency and energy contours, for recordings of six talkers reading the Rainbow Script, two talkers reading a paragraph composed of…

In order to effect the unambiguous identification of particular members of sets of homonyms--homophones or homographs as the case might be--during the automated conversation of written language to spoken language and/or vice versa, additional linguistic information must become available regarding the primary thought-to-physical-manifestation…

Technical features of Penn State's Instructional Media Center are described. Unlike many other instructional units, special attention has been paid to the physiological requirements for learning in its design and construction, i.e., acoustics, lighting, visibility, and air conditioning. The building contains many unique features which may be…
