Face-to-face conversations between scientists and public audiences in an informal learning environment provide a valuable opportunity to support public engagement with scientific research. These types of experiences have significant benefits for members of the public and for scientists. For public audiences, interacting face-to-face with a scientist can expand awareness of the range of careers in science, spark new questions about scientific topics, and increase interest in learning more about the scientist’s topic (Tisdal, 2011; Ong, 2014).

This article describes the research and development of an NSF-funded, five-year experimental program to strengthen informal (out-of-school) STEM learning by youth in five rural communities.

These STEM Guides were respected adults with credible connections to youth, flexible schedules, the ability to travel within the community, and enthusiasm for identifying local STEM resources. The Guides were
