This document consists of three separately published fact sheets (for parents and teachers of children who are deaf-blind) combined here because of the close relationship of their subject matter: (1) "Communication Interactions: It Takes Two," by Kathleen Stremel; (2) "Expressive Communication: How Children Send Their Messages to You," by Kathleen Stremel; (3) "Receptive Communication: How Children Understand Your Messages to Them," by Rebecca M. Wilson. The first fact sheet defines communication; suggests ways to find opportunities for interactive communication; offers specific suggestions for improving interactions (such as interacting often, allowing the child to participate in as many activities as possible, and providing examples for others); and gives an example. The second fact sheet defines expressive communication, lists reasons to communicate, explains use of a communication map to assess the child's expressive communication, recognizes the progressive nature of communication development in planning and individualized program, and presents guidelines for developing an effective communication program. The third fact sheet defines receptive communication, offers tips for sending effective messages, and explains use of a communication map to evaluate the child's current receptive language abilities and design a program for the child based on his/her hearing and vision, motor abilities, and cognitive abilities. Each fact sheet also includes an annotated list of suggested resources. (DB)
