Biographic Sketch Gary H. Girty



I have taught structural geology, and both introductory and advanced field methods for the past 30 years at SDSU. During this time I also have successfully supervised the completion of 78 MS and 96 senior theses, and have published 71 papers, 8 guidebooks, and at least 85 abstracts. The great majority of my publications were coauthored with students at SDSU.

In addition to the above, I have developed an online and a blended (mix of online and conventional lecture) introductory geology course and an online natural disasters course. The web sites supporting these classes both consist of (1) an electronic text book that I wrote, (2) a set of videos (screencasts) of all of my lectures, (3) practice exams (study guides), and in the case of the introductory geology class (4) a complete laboratory manual. I am the sole author of all of this material and own the copyrights. The web sites can be found at and

The free laboratory manual is used in our standard introductory lab. In addition, I have developed a CD (Notes on Planet Earth) for the introductory geology class that allows students to print out all of the written text material along with colored illustrations on a chapter by chapter basis. The CD is available through the bookstore at a cost of ~$15.00.
During the 2005/2006 academic year I implemented the Geoscience Concept Inventory assessment instrument for the online introductory geology class. A summary of the results of the GCI can be found in Girty and Carrasco (2008) (Geological Society of America Abstracts with Programs, v. 40, p. 90. ) or at the following link:
