OUTSIDE: Over Under and Through: Students Informally Discover the Environment will focus on conducting a pilot study of our informal environmental education nature program designed for underrepresented middle school students in Mississippi. We have partnered with the University of Southern Mississippi's (USM) well-established Biological Sciences Learning Center (BSLC) and newly developed Lake Thoreau Environmental Center (LTEC), the Mississippi Museum of Natural Science and the Hattiesburg Public School District (HPSD). We are focused on reaching two target populations of participants: future naturalists and underrepresented middle school students. During this pilot, we are training volunteer naturalists to lead engaging, inquiry-driven informal environmental education programs designed to immerse middle school students in nature. We have developed a training program for volunteer naturalists and captured patterns in learning and interactions between students and naturalists during OUTSIDE programming.
