This guide provides basic information on the development, observation, and teaching of basic language, visual-perceptual-motor, and body awareness and control skills to disadvantaged children. It is presented in three sections devoted to specific analyses of how skills develop within each of three modalities, and how to observe and teach children to be more effective information processors in the specific modality under consideration. Such discussion is intended to provide the teacher with the information necessary to understand the overall level of functioning of a class of children, as well as each particular child's pattern of skills. This facilitates the organization of a general teaching program and the individualization of the program to the needs of the group and to those of particular children. (JM)
