Earth science education
Earth Science Education Research focuses on understanding how people learn about the earth in classrooms, in laboratory settings, in the workplace, and in the field. It also focuses on the systematic study of how teaching Earth science can be improved in all of these settings. This kind of research uses methods drawn from the social sciences, such as laboratory experiments, interviews, surveys and classroom or field observations. Our research generates new theories about how people learn Earth science, new ways to measure skills and knowledge and rigorously tested new approaches to teaching. Our aim is simple: through this research we will improve student, teacher, and public understanding of the geosciences and ensure a broad, diverse and well-prepared future geoscience workforce.
Specific areas of research include: The role of spatial skills in tasks as diverse as geoscience fieldwork, sketching, remote sensing and weather forecasting; comparison of novice and expert approaches to solving geoscience problems; the role of fieldwork in undergradaute geoscience education; developing and testing new Earth science curricula and classroom approaches at the K-12 and undergraduate levels; understanding barriers and opportunities for minority student participation in the geosciences at community colleges and minority-serving institutions; preparation and professional development of K-12 teachers.

Geoinformatics and spatial data analysis
The Department of Geological and Environmental Sciences has developed a strong research emphasis in the areas of geoinformatics and spatial data analysis. Research in these fields is being enabled by the acquisition of a state-of-the-art remote sensing facility and the installation of a real-time receiving station.
Projects: Several ongoing projects address the potential influences of natural processes, global change and regional human activities on the water and carbon cycles and on ecosystems. Dr. Mohamed Sultan and his collaborators develop and apply an integrated systems approach to assess, monitor and model the recent and future impacts of changes in the landscape and land cover. Remote sensing and geographic information systems are being used to analyze and visualize spatial datasets to address a wide range of hydrologic and environmental problems.

The Department of Geological and Environmental Sciences has a long history of geophysics research. Expertise and resources of the department have been applied in mapping natural resources which opened new avenues for geologic research.
- Geophysical research has been applied in the following areas: Assisting in archaeological research; developing custom ground penetrating radar antennae; ground water supply and contamination problems; locating lost and abandoned water and monitoring wells; mapping glacial drift thickness; mapping of the sub-bottom of Lake Michigan; sedimentary basin analysis; reservoir characterization and petroleum exploration.
The Department of Geological and Environmental Sciences is actively involved in mapping the glacial geology of southwestern Michigan through the National Geologic Mapping Act of the U.S. Geological Survey. This program is part of Michigan Geological Survey's mapping program. The land forms and sediments are studied to understand the stratigraphy, chronology and glacial depositional processes involved in their formation.
- Mapping provides geological information for use in: Aggregate resource location; land use planning; decision making involving location of waste disposal facilities and well head protection.
- Research methods include: Clay mineralogy; gamma ray logging of test holes and newly drilled water wells; test drilling by rotasonic and other techniques.

Igneous petrology and high-temperature geochemistry
This research program is focused on the origin and evolution of magmatic intrusive and extrusive systems with special emphasis on the formation of economic sulfide mineral deposits. The program combines field and laboratory based studies on igneous rock occurrences.
Facilities: The research group uses the Economic Geology and Stable Isotope Geochemistry laboratories in Haenicke Hall for its lab-based investigations. The commonly used lab-based research methods include petrographic observations from hand-sample and thin section studies, major, minor and trace element geochemistry and sulfur isotope geochemistry. A Delta-V Isotope Ratio Mass Spectrometer and an Elemental Analyzer are used for determination of sulfur isotope data. Electron microprobe analysis is used by this group in collaborative studies with other research institutions.
Projects: The members of the research group have been involved in projects on the magmatic and tectonic evolution of areas such as the Upper Peninsula of Michigan and southeastern Alaska. Igneous activities associated with convergent tectonic events such as the 1.8 Ga old Penokean Orogeny in UP Michigan and northern Wisconsin is one of the areas of study. The group is also involved in the preparation of geological maps of focus areas in UP Michigan for the Michigan Geological Survey, as a part of the Statemap program funded by the United States Geological Survey.
