One of nine competency-based training modules for personnel preparation in early childhood special education, this guide focuses on behavior management and development of self control. All modules are adaptable for use with a general audience, direct service personnel, or administrators and are based on the following principles: developmentally appropriate practice; integration of children with disabilities with typically developing peers; collaborative relationships with families; attention to individual needs; and provision for and valuing of diversity among young children and their families. Modules are intended to be used in whole or in part, in groups or for self-instruction. Each module comprises goals; competencies (knowledge, skill, and values and attitudes); and objectives, with a matrix for each objective identifying enabling activities, resources, and leader notes. Relevant handouts, forms, and readings are provided for each objective. This module offers activities to increase understanding of the following factors of behavior management: the environmentally sound preschool; developmentally appropriate behavior; the least restrictive setting; and collaboration with families. The module stresses preventive approaches to foster the development of self control in the areas of social competence, self-esteem, systematic interventions, and communication skills in all children, as well as knowledge of when and how to seek additional help.
