AB: In the summer of 2004, the Lunar and Planetary Institute hosted 25 middle- and high-school teachers on a week-long field experience in Idaho and Montana. This workshop mixed field work with classroom experiences and provided educators and scientists the opportunity to interact. The educators investigated deposits associated with Glacial Lake Missoula floods and lava flows in the Craters of the Moon National Monument and Preserve. The participants applied what they learned about Earth-based processes to develop understanding of processes operating on Mars and the most recent results from NASA's missions to Mars. This was the most recent of five field-based experiences that used Earth-planet comparisons as a basis for experiential learning. These field experiences all are designed to strengthen content knowledge of geologic processes and planetary sciences. Learning geology through fieldwork enables participants to take ownership of the content through real-life experience; in essence, the teacher becomes the student. Establishing deeper knowledge of the content increases their confidence in facilitating inquiry-based science in their own classrooms. In addition to content, the educators are immersed in the process of science. Participants make observations, compile notes and illustrations, debate interpretations, draw conclusions, and communicate findings. Care was taken to separate observations and interpretations to help build an understanding of scientific reasoning. Discussions often involved questions without solutions, or with multiple solutions. While some participants expressed discomfort with these aspects of the nature of science, most were more comfortable with open-ended, inquiry based exploration by the close of the workshop. The field work is coupled with discussion and activities in the classroom. Participants reflected on the field sites and placed them in the context of the geologic history of the region. Observations and interpretations at individual field stops were related to planetary observations. The educators worked in small groups to develop a virtual tour of the different field stops, intended for use by their students. Development of the virtual tour allowed participants to solidify knowledge and enabled instructors to verify comprehension. The Web site became an educational tool, prompting further discussion and investigation. Field work was complemented by hands-on, inquiry based, standards-based classroom activities. Because the activities related directly to processes observed in the field, the participants were able to make detailed observations and were better able to make connections with the content. They were more confident in identifying where the activities served as strong models and where the activities failed to model the real world. The participants were more comfortable asking questions and experimenting with variables. In the next several months, the participants will be surveyed in an effort to track how the experience is incorporated into the classroom and leveraged across the educational community. We are grateful for support from NASA's Office of Space Science and Sandia National Laboratories.
