Air Toxics Under the Big Sky: Examining the Effectiveness of Authentic Scientific Research on High School Students' Science Skills and Interest.

Air Toxics Under the Big Sky is an environmental science outreach/education program that incorporates the Next Generation Science Standards (NGSS) 8 Practices with the goal of promoting knowledge and understanding of authentic scientific research in high school classrooms through air quality research. A quasi-experimental design was used in order to understand: 1) how the program affects student understanding of scientific inquiry and research and 2) how the open inquiry learning opportunities provided by the program increase student interest in science as a career path. Treatment students received instruction related to air pollution (airborne particulate matter), associated health concerns, and training on how to operate air quality testing equipment. They then participated in a yearlong scientific research project in which they developed and tested hypotheses through research of their own design regarding the sources and concentrations of air pollution in their homes and communities. Results from an external evaluation revealed that treatment students developed a deeper understanding of scientific research than did comparison students, as measured by their ability to generate good hypotheses and research designs, and equally expressed an increased interest in pursuing a career in science. These results emphasize the value of and need for authentic science learning opportunities in the modern science classroom.

The Clean Air and Healthy Homes Program: A Model for Authentic Science Learning.

The Clean Air and Healthy Homes Program (CAHHP) is a science education outreach program that involves students in research of their own design related to indoor and outdoor air pollution and links with respiratory health. The program, which provides equipment, lesson plans, and support to middle and high school classrooms and professional development for teachers, is an excellent model of how to engage students in relevant and authentic science research and learning. This article describes the current program, how it promotes authentic science learning in secondary science education, and the positive impact it has had on student learning and attitudes.'

The Power of the Symposium: Impacts from Students' Perspectives.

The Air Toxics under the Big Sky program developed at the University of Montana is a regional outreach and education initiative that offers a yearlong exploration of air quality and its relation to respiratory health. The program was designed to connect university staff and resources with rural schools enabling students to learn and apply science process skills through self-designed research projects conducted within their communities. As part of the program, students develop and conduct independent projects, then share their findings at the conclusion of the school year in some type of interactive capstone experience, the most prominent being a high school symposium held at The University of Montana campus. Student feedback collected through a carefully controlled evaluation program suggest that the annual symposium as the culminating event is a critical component of the Air Toxics Under the Big Sky program, and a valuable learning experience as many of the students go on to post-secondary education.

The Big Sky Model: A Regional Collaboration for Participatory Research on Environmental Health in the Rural West.

The case for inquiry-based, hands-on, meaningful science education continues to gain credence as an effective and appropriate pedagogical approach (Karukstis 2005; NSF 2000). An innovative community-based framework for science learning, hereinafter referred to as the Big Sky Model, successfully addresses these educational aims, guiding high school and tribal college students from rural areas of Montana and Idaho in their understanding of chemical, physical, and environmental health concepts. Students participate in classroom lessons and continue with systematic inquiry through actual field research to investigate a pressing, real-world issue: understanding the complex links between poor air quality and respiratory health outcomes. This article provides background information, outlines the procedure for implementing the model, and discusses its effectiveness as demonstrated through various evaluation tools.

Patterns of asthma symptoms and perceptions of harm from seasonal atmospheric events in rural Western Montana.

To characterize the frequency of and relationship between self-reported asthma symptoms and physician-diagnosed asthma, identify seasons associated with heightened symptoms, and describe the influence of seasonal atmospheric events and ambient environmental factors on asthma symptoms and perceptions of harm, a seven-county region of Western Montana was surveyed, utilizing a two-stage sampling method. Respondents were queried concerning asthma-related history, symptoms, and environmental concerns. Of 2,790 respondents, 12% reported physician-diagnosed asthma. Eighteen percent reported one or more and 9% reported two or more asthma-related symptoms. Over 70% of asthmatics reported worsened asthma symptoms during wildland-fire smoke exposure. Of those reporting summer as the season they experienced the greatest breathing problems, 81% reported breathing problems from wildland-fire smoke (p < 0.01). Of those reporting worsened symptoms in fall or winter, 61% reported breathing problems during winter inversions (p < 0.001).
