Virginia Master Naturalist volunteers are well-positioned to help more people of all ages and backgrounds to have regularly occurring, meaningful experiences in nature that meet their personal interests and needs. As volunteer educators, they may provide interpretive talks, lead interpretive walks, develop interpretive brochures and signage, and give formal presentations. The foundation for all of these forms of education includes knowing one's audience; planning topics, themes, goals, and objectives; background research and preparation; communicating clearly; and evaluating. This publication describes these key concepts and provides step-by-step guidelines for planning interpretive programs and other educational interactions.
