Julia Johnson

Julia K. Johnson earned an M.S. and Ph.D. in structural geology and geoscience education. Dr. Johnson is a full-time faculty member in the School of Earth and Space Exploration at Arizona State University (ASU), where she teaches Introduction to Geology to nearly 1,000 students a year and supervises the associated introductory geology labs. She also coordinates the introductory geology teaching efforts of the School of Earth and Space Exploration, helping other instructors incorporate active learning and inquiry into large lecture classes. The main focus of her geoscience education research is on student- and instructor-generated sketches for learning, teaching, and assessment in college geology classes. Before coming to ASU, she conducted groundwater studies of copper deposits and taught full time in the Maricopa County Community College District, teaching physical geology and environmental geology.
