Designed for middle school grades, the National Geographic Geo-Inquiry Process engages students in geographic inquiry that begins with formulating a question that addresses an issue in the local community and ends with taking informed action to advocate for a specific, concrete solution. This research employs a pretest and post-test in classrooms in five schools to assess changes in students' geography competencies, inquiry skills, and self-efficacy in civic engagement after undertaking a geo-inquiry project. In addition, this article provides a context for geo-inquiry to include its development, articulation with state standards, and example projects.
