The physical and emotional manifestations of burnout are described. A five-phase model is outlined for preventing extensive stress leading to teacher burnout. Phase One is predicated upon the notion that a professional cannot manage stress without the ability to identify it. Descriptions are given of the signs of physiological, psychological, and behavioral stress. Phase Two involves an analysis of the sources of stress. Lists are provided of common stressors within the family environment and the professional workplace. The cognitive and physical factors that emerge as internal sources of stress and potential burnout are discussed. The cognitive factors concern the thoughts, ideas, beliefs, and perceptions regarding the activating events in one's life and the various experiences in day-to-day living. The physical stressors have the most harmful long range effects on the human body. The third phase of the preventive model offers suggestions on how to develop a stress management plan. This includes relaxation exercises, cognitive restructuring, health habit changes, situational changes, time management, and obtaining social support or help from others. Phases Four and Five of the model consist of implementation of the stress management plan and evaluation of its effectiveness. (JD)
