This volume, the second in a series of seven, contains the four learning modules which focus on the first Child Development Associate (CDA) competency (setting up and maintaining a safe and healthy learning environment) in the performance based curriculum of the Texas A & I Bilingual Bicultural Child Development Associate Training Program. The curriculum was designed for training preschool teachers working with Spanish dominant migrant children, from age 3 to school entrance age, in South Texas. The competency covered in this volume is divided into the functional areas of safety, health, outdoor environment, and indoor environment, and a learning module is provided for each of these functional areas. Each module includes (1) an explanation of how it is to be completed; (2) a description of the performance objectives; (3) a pre-assessment instrument; (4) three alternative cycles of learning activities, each cycle divided into four skill areas (diagnostic, prescriptive, implementation, assessment); (5) a narrative of information about the functional area; (6) the script for a filmstrip to be used with the modules; and (7) a post-assessment instrument.
