Today's high school students and biology teachers alike face challenges arising from constantly-changing environments. From global warming to species reduction to energy policy, the issues the students will face will have immediate and long-lasting implications. At the same time, biology teachers are charged with achieving legislated standards, including biological science standards, within their public school systems. One program that brings real-world scientific research into the classroom via technology is CHANCE--Connecting Humans and Nature in the Costa Rican Environment. This program transforms teachers into field researchers, who then translate their experiences to research-based Internet "modules" that bring the experience to the classroom. By using a field course inquiry-based learning model, shown to be effective in enhancing student comprehension, the modules help teachers create hands-on, research-based activities that bring scientific principles to life. CHANCE was designed to address the needs of school districts across Pennsylvania, and the Pennsylvania Department of Education (PDE) now recommends the use of CHANCE modules as a way of helping high school students meet state standards in environmental science and ecology. However, since teachers in every state must meet similar standards, the CHANCE program provides a viable framework for renewing high school biology education nationwide. This paper provides an overview of the program, its unique learning model, and the modules that support the model's classroom implementation. (Contains 4 tables and 4 figures.)
