FINDING FAULT: LABORATORY EXPERIMENTS AND CLASSROOM STUDIES ON IDENTIFYING FAULTS IN IMAGES
In the classroom studies, students’ accuracy in identifying faults generally improved. For those photos on which students showed the greatest improvement, key factors appear to be distinguishing faults from fractures and identifying offset layering, particularly where layering is subtle and the offset is not eroded. In the laboratory experiments, initial instructions that included two similar images of faulted and unfaulted layers led to the highest performance at identifying faults in the outcrop photos. In fact, participants who were shown two similar images of faulted and unfaulted layers were approximately as successful at identifying faults in outcrop photos as geology students taking the end-of-semester post-test. We will discuss the implications of both of these studies for effective instruction to help students learn to identify faults in images.
