A learning module is a competency-based tool focused on what a learner will know or be able to do as a result of using the tool. Modules are especially suitable for outcome-based adult learning programs that emphasize self-direction and individual or small group approaches. Although learning modules vary greatly, six essential components are as follows: a statement of purpose, introduction to module use, learning outcomes, learning activities, learning resources, and evaluation procedures. For a module to be useful, congruence must be evident between learner needs and its content. Special attention should be directed to outcomes, activities, and evaluation procedures. Effective modules outline material clearly and attractively. Content is distributed logically and creatively; information is accessible. An outline of content should be completed prior to development of any written or audiovisual material. An arrangement for a typical, well-organized module is as follows: cover and back pages, title page, copyright page, statement of purpose, table of contents, foreword, learning session chapters, and appendixes.
