A quality control model is proposed to facilitate development of effective instructional programs. The theories of R. M. Gagne and of M. D. Merrill provide the foundations for a theory of sequencing behavior into a hierarchical order in order to improve the learning potential of an instructional program. The initial step in the procedural model is to identify the enabling objectives which allow performance of the terminal objective. After these objectives are identified and hierarchically charted, the sequence is validated by a task analysis. An evaluation by individuals for whom the program is designed should eliminate ambiguous directions. The next step in the model is an empirical validation of the entire program to determine if the student reaches the terminal objective successfully and if the sequencing is effective and efficient. Finally the program is revised according to the results obtained in the preceding step and recycled until an acceptable criterion is reached. (JY)
