A case is made for the use of computer assisted instruction (CAI) in Child Development Associate (CDA) training programs conducted on-campus in conjunction with an educational curriculum or conducted off-campus in conjunction with child care programs. The following points are made: (1) CAI can be used to supplement and amplify a teacher's effectiveness; (2) CAI initially requires only a minimal introduction to computer use; (3) Computer-based self-instructional materials evolve in coordination with changes in national policy and practice; (4) Certain components of CDA competency-based training appear directly related to computerization; (5) CDA trainees using CAI gain knowledge of ways computer technology can be used in preschool settings; (6) Computer simulation with feedback to trainees' responses provides opportunities for increased learning; and (7) When employed in conjunction with pretests and posttests, CAI modules can be used in individualized self-evaluation interviews to facilitate learning and concept development. By way of illustrating this last use, segments of a CAI program based on a specific CDA competency are presented. Confronting trainees with hypothetical situations, the program segments indicate how computer-based self-instruction can enhance theoretical linkage between CDA competencies related to guidance and discipline and can teach discipline strategies based on behaviorist, interactionist, and nondirective approaches.
