ABSTRACT The goal of this field excursion is to provide an opportunity for focused exploration of field-based teaching and learning. Learning in the field is an essential element in the education and development of geology students, but until recently has received relatively little attention by education researchers. Set against the backdrop of classic bedrock localities of the Midcontinent Rift System in northeastern Minnesota and using new knowledge of how people learn, of learners, and of pedagogical practices, this excursion explores goals for student learning in the field and effective instructional practices for helping students realize those goals.
