Instructional modules are self-contained units that include all the information and materials necessary for mastery of one or more competencies. One module design consists of seven components: a) a description of the field in which competency is to be demonstrated; b) the concept and rationale for including the module in the total program; c) the specific skill to be developed; d) objectives, or a delineation of anticipated student behavior; e) the specific objects, readings, instruments, and other instructional materials which will facilitate competency development; f) the learning activities to be undertaken by the student in order to achieve the module objectives; and g) assessment procedures and evaluative instruments that relate specifically to the behavioral objectives of the module. Analytical attributes of an instructional module are its conceptual level; content area; learning and instructional modes; access skill focus (observation, listening, and/or reading); competency target (age or grade level); and estimated completion time for the module. There are several approaches to module development, but in general, the most effective is cooperative development by two or more instructors who pretest and refine the module before including it in the total program.
