Both the nature of theory and the way it is taught can overpower health education practitioners. As a consequence, myths which maintain theory and practice in separate realms may develop. This paper argues that to remedy this situation, practitioners must be helped to gain greater control of theory. Specific suggestions for accomplishing this goal are offered in a three-part prescription. First, concepts and teaching methods are introduced to dismantle myths about theory and to help practitioners understand its origins, nature, and functions. Second, health educators are encouraged to acknowledge limitations in theories currently guiding their practice. Third, they are shown ways they can exert leadership in developing theory to fill these gaps and build a more adequate knowledge base for confronting contemporary practice problems. Through this exercise of power, health educators will gain control over theory and expand the boundaries of practice, while also enhancing their professional status. The boundaries of professional practice are made and changed by the relationship between the discourse of scientific knowledge and the exercise of professional power.1 Turner
