The Park Stewards program, sponsored by the University of Phoenix, gives high school teachers and students the opportunity to explore the relevance of national parks to their lives, and enables them to become civically engaged stewards of their national parks through year-long service-learning projects. These service-learning activities allow students to apply academic knowledge and critical thinking skills (in addition to physical skills as appropriate) to address genuine needs of the park. The resulting curriculum engages their students and meets all local, state, and national education standards.
