The reference manual of preferred sign language signs represents an effort by a special South Carolina task force to develop a single, systematized approach for signing in instructional settings throughout the state. The manual, which contains illustrations and instructions for formation of approximately 2,500 signs, was developed by establishing a word list of essential vocabulary utilized in the primary grades and then identifying preferred signs for each of the words/concepts. Among 11 guidelines used in establishing the preferred signs were: English, American Sign Language, or Pidgin Sign English word order; the use of Total Communication when appropriate; the use of fingerspelling when appropriate; discouragement of the invention of signs; use of correct signing space; and use of the English representation of the verb "to be'" An introduction provides information on the history of sign language, terminology, the sign language continuum, manually coded sign systems, features of sign language, grammar of sign language, and fingerspelling. Provided for each sign are an illustration, a sample usage, and formation instructions. Appended are the signs for the American Manual Alphabet, numbers, ordinals and money, the days of the week, and cities in South Carolina. (DB)
