The purpose of this project was to develop, implement, and evaluate a simple, teacher-friendly, environmentally-based anxiety reduction intervention for fourth-grade students. Review of related literature indicates that children are often victims of stress due to academic and sociological variables which exist within the school environment. Specifically, researchers have found that fourth-grade students encounter increased academic pressures which may put them at greater risk for stress. The purpose of this project was to develop, implement, and evaluate a simple, teacher-friendly, environmentally based anxiety reduction intervention for fourth-grade students. The intervention, titled Project SESAME (Student Environmental Stewardship Anxiety Management Exercises), contains activities which focus on teaching students about anxiety reduction within the context of environmental stewardship (accepting personal responsibility for environmental protection). The effects of the intervention on 113 students were evaluated by using the Spielberger State-Trait Anxiety Inventory for Children. Results indicated that there may have been a change in student state/trait discrimination capabilities. This outcome may be significant in that stress management interventions for children may need to focus on training participants to distinguish between varied forms of anxiety before the intervention in order that the intervention be effectively implemented and carried to a successful completion. Appended to the document are: (1) originals for overhead transparencies containing information about the intervention and its outcomes; and (2) six lesson plans, including objectives and learning activities.
