Welcome to Exploring the Environment™ (ETE). The ETE online series, which features an integrated approach to environmental earth science through modules and activities, is developed at the NASA Classroom of the Future™; at Wheeling Jesuit University. Through a cooperative agreement with the NASA Goddard Space Flight Center, the ETE online series is supported by NASA's Information Infrastructure Technology and Applications (IITA) Program, which facilitates public use of Earth and Space Science remote sensing databases over the Internet.

The vision of the ETE online series is to promote science-literate and reflective students who are knowledgeable of the earth's processes and their responsibilities for stewardship. The problems in the ETE modules and activities ask students to address human activities and their impacts upon the environment. The modules and activities incorporate environmental issues such as water quality, deforestation, biodiversity, volcanoes, ozone depletion, and global climate change.

Featuring problem-based learning (PBL), the ETE series provides students with tools to investigate scientific, social, political, and cultural aspects of controversial, authentic environmental problems. Standard problem-solving models, online resources that include relevant satellite imagery, and recommendations for extended inquiry are available to students.

Student-directed research generally lasts a minimum of five weeks but often extends throughout the semester. Working cooperatively or individually, students engage in problem-based modules and activities that require them to formulate problem statements; to collect and analyze data; and then to prepare and present their findings, solutions, or recommendations. These findings, solutions, or recommendations should demonstrate students' understanding and awareness of the dynamics of both physical/biological and socio-economic variables.
