Project CDCC (Career Development Centered Curriculum) provides career development instruction to rural, elementary-level students. The objectives are to help students demonstrate increased awareness of life roles, formulate realistic self-concepts, and develop and use decision-making skills. Through a process which included testing and refinement, twenty-seven units containing 141 performance objectives were developed to integrate career awareness into existing subject material. The units include learning and practice in math, communication arts, science, and social studies; they employ various teaching strategies and techniques, such as activity sheets, classroom discussion, audiovisuals, role playing/simulation, and field trips. The materials were pre- and posttested using (1) a field test site (up to four years of student exposure and units taught between testing periods), (2) an experimental site (one year of student exposure and units taught between testing periods), and (3) a control site (units not taught between testing periods). There were substantial posttest performance differences between experimental groups and the control group in favor of the former. Also, greater results were shown at any grade level if the students had taken the CDCC units at lower level. Educational assessment data indicated that implementing career education activities did not hurt academic achievement. (CSS)
