One of a series of 18, this Child Development Associate (CDA) training module provides a guide to promoting acute hearing and sound discrimination in young children through both group and self-selected music activities. Upon completion of this module the trainee is expected to be able to provide daily music experiences; emphasize enjoyment of and participation in music activities; provide a music center; plan, execute, and evaluate at least five learning experiences in music; execute and evaluate a minimum of five incidental learning experiences; utilize music to guide children's behavior and to adjust the noise level of a classroom; utilize music as a resource for teaching skills and concepts in other areas; and provide music activities to develop children's auditory and motor skills. Early sections of the module define terms and suggest a procedure by which trainees can evaluate their strengths and weaknesses. Subsequent chapters focus on the function of music for the preschool, teaching music in the preschool, and activity development. The module also provides 14 learning activities, ranging from resource unit development to stories for music. Supplemental books and pamphlets are listed. (RH)
