With this Child Development Associate (CDA) training manual the CDA intern can learn to teach language arts to preschool children in ways that foster their cognitive development. Upon completing the module, the trainee is expected to know how to read a story to preschool children, teach a lesson using an experience chart, set up a reading and listening center in a preschool classroom, and teach a lesson to children on writing their own books. Instructional and behavioral objectives for learning activities are given. The teacher's materials include pre-test, the field supervisor's directions, a resource persons activity list, and directions for student activities. The student's materials consist of pre- and post-tests, an activity record, a glossary, lesson overviews and directions, and 15 lessons. A brief discussion of cognitive development among preschool children is included. (Author/RH)
