Inherent in this interaction is man's unique ability to communicate verbally and non-verbally with his biological, psychological and sociological environment in an orderly and logical manner. During his life span man strives to maintain equilibrium or health by adapting to stressors in his environment. Health and illness form a continuum along which man can be located at any time. Illness results when his adaptive mechanisms fail, thus requiring intervention to resolve or limit the effects of stressors in order to regain health. Society is an interaction of systems which is in constant change.
Society is built by man and reflects man's culture, laws, mores, and lifestyles.
Societal groups are made up of individuals and reflect the thoughts, feelings, and attitudes of the people who are a part of the society. Education is a system of change through which learning is brought about. Education is a structured and progressive process aimed toward expected outcomes and, as the learner participates in this process, knowledge is gained. Learning is a change in behavior which results from the acquisition of knowledge and may or may not be directly observable. Acquisition of knowledge takes place within the learner and bears a direct relationship to one's own motivation and individual effort.
