As the focus on developing our nation's scientific workforce intensifies [National Academy of Sciences, 2007], more geoscience departments are recognizing teacher preparation as an integral part of their work. Skilled geoscience teachers can excite and engage K–12 students in the geosciences, present geoscience as a rewarding career path, and ultimately contribute to a better understanding of key geoscience problems among the public. Our ability to achieve these goals starts with the quality of our teacher education programs.
