A rationale is offered for incorporating relaxation training in elementary school classroom activities. Cited are research studies which focus on the reaction of children to stressful life changes and resulting behavioral and physical disorders. A list is given of significant life events which may be factors in causing diseases or misbehavior in children. Described is a unit which adapted such techniques as yoga, deep muscle relaxation, and guided visual imagery to help primary age children cope with stress. Included in the unit, designed to be both experiential and cognitive, are pictures and cartoons depicting people in stressful situations, charts illustrating the reaction of the human body to stress, dramatic play stories designed to teach specific relaxation skills, and descriptions of relaxation periods in the classroom. A discussion is presented on implementing and evaluating a unit of this type. A bibliography and a list of resources for relaxation techniques are included. (JD)
