Two settings build the premise for this chapter and comprise the Connecting Humans and Nature through Conservation Experiences (CHANCE) program. The first setting is a summer field course in Costa Rica and the second is the regular school classroom during the academic year. The first setting builds the foundation for the second. Both elements of the CHANCE program, the field course and the modules, offer teachers an up-to-date alternative to traditional professional development and curriculum opportunities. Based upon ongoing research and evaluation findings, the CHANCE program continues to evolve. The program supports the learning of scientific inquiry skills and the vision of the National Science Education Standards (NSES).
