This workbook for developing communication in learners with severe disabilities is from the Mississippi Early Education Program for Children with Multiple Disabilities, a program designed to train Individuals with Disabilities Education Act Part H service coordinators and service providers to use family centered strategies. The objective of the training is to teach practitioners: (1) the different forms and functions of receptive communication and expressive communication through demonstrations and written activities; (2) skills in assessing the learner's current level of receptive and expressive communication skills; (3) skills in determining the content of communication skills across domains and activities for teaching; and (4) skills to complete a communication map. The features of an individual communication system are described and include a way to communicate, a reason to communicate, something to communicate, somewhere to communicate, and someone with whom to communicate. Included in the module are a pretest and posttest, 10 activities to illustrate concepts, a communication map, and sample forms to track students' abilities and progress. Transparencies summarizing key information are also provided. (CR)
