The University of Montana (UM)—Missoula has implemented a problem-based program in which students perform scientific research focused on indoor air pollution. The Air Toxics Under the Big Sky program (Jones et al. 2007; Adams et al. 2008; Ward et al. 2008) provides a community-based framework for understanding the complex relationship between poor air quality and respiratory health outcomes by teaching students chemical, physical, and health concepts in the classroom setting. In addition to designing controlled experiments, students are guided through the process for conducting independent research projects to explore a real-world issue in their communities.
