The module is the third of a series of seven discrete modules designed to assist elementary school teachers in the development of a career education program to enrich an already established program. Module 3 may be used separately or in conjunction with the other modules. The module contains seven units and is intended to help define self-concept, examine several self-concept theories, and relate the learner's self-concept to career choice. Distinction is made not only between several self-concept assessment instruments, but also between several self-concept development programs that are available commercially. Finally, the process for developing a written grade level program of learning activities on self-concept development for elementary school children is addressed. The document also contains supplementary references for the module. (Author/LJ)
