My responsibilities as an ASU Professor revolve around

• supporting the School of Geographical Science's goal to better its position as one of the very best geography units in the nation and maintain Geography's status as the National Research Council's highest ranked Ph.D. program at Arizona State University, and

• supporting the mission of ASU to provide opportunities for self-advancement and life-long learning for persons living within the Phoenix metropolitan area

My research interests rest on the geography of rock and mineral decay (weathering).  In particular, we are losing our collective priceless global cultural heritage of rock art daily through human and natural weathering processes.  Thus, I feel an imperative to focus my expertise to help rock art researchers understand what geographical information can be extracted rock art before it is lost forever.

For your convenience, I present here a series of  presentations on the aspect of the geography of weathering that offers the greatest potential to understand rock art. Rock Varnish: An Internet Primer for Rock Art Research can be used freely in your teaching and educational efforts.  (The only restriction is that you may not sell a product using the imagery.)

A more conventional presentation of my research activities can be found in short and long vitae.
 

TEACHING RESPONSIBILITIES

Teaching rests at the heart of my job and the reason why I chose to be a Professor instead of a Research Scientist at a laboratory.

Some professors desire to be a Sage on the Stage or a Professor on the Pulpit; I do not.  There are others who consider themselves the Gatekeeper of Grades, giving out only a few As and Bs; I eschew this perspective as unethical.  All students should be guided to earn As.

Rather, I maintain a consumer-oriented approach, because college is enormously expensive in your money and time (click here to see research indicating that professors can save students lots of money by investigating the use of online readings, instead of outrageously expensive textbooks).  Through my hopefully entertaining and enthusiastic teaching, I want to help students achieve their goals.  Sometimes, this involves one-on-one discussions on how to succeed in college.  Other times, it involves helping students master course material.  Still other times, I simply help with minor corrections to a student's path and then act as cheerleader. 

The bottom line is that I want each student to master my course objectives and receive top grades. But that job of mastering course objectives remains the responsibility of the student. Ma ka hana ka 'ike says it all in Hawaiian: in the work is the knowledge. I cannot and should not do this work for you to learn. Ultimately, this old axiom remains true even of today's  ipod generation students:

I hear for the first time, I forget.
I read for reinforcement, I try to remember.
I see, I question.
I do for myself, I learn.
I teach to others, I understand.
I reflect after teaching, I improve.

SERVICE ACTIVITIES

Because intelligence and hierarchy do not mix well, professors try to maintain a system of distributed responsibility to ensure that a department's mission is not only met, but exceeded. This "service" takes different forms, based on desires and abilities of different faculty members. In my case, most of my service activity rests in helping coordinate and assist K-12 geography education in Arizona as co-coordinator of the Arizona Geographic Alliance.
 

ADVISING RESPONSIBILITIES

Officially, I advise those interested in receiving a B.A.E. degree in geographic education (please click here to see a PDF of the Geography BAE check sheet) and honors students in geography.  I am also very happy to discuss classes, careers and and other matters related to geography and education.  For advising, please stop by during office hours or, even better, e-mail me to make an appointment at ronald.dorn@asu.edu.
 

A FAVORITE DISCOVERY: Desert Pavement Formation from Accumulation of Aeolian Fines

Mabbutt, J.A. 1979. Pavements and Patterned Ground in the Australian Stony Deserts. Stuttgarter Geographische Studien, volume 93, p. 107-123
p. 112-3: "Very commonly an aeolian origin is postulated for the silty clays which commonly constitute the stone-free horizons beneath stone pavement sin the Australian deserts.  This is in accord with their size-grading, in which they resemble other deposits of acknowledged aeolian origin in arid south-eastern Australia (BUTLER 1956), and with their uniformity and great extent over the southern Australian arid zone.  A transportational origin is suggested by the way in which they uniformly blanket a wide range of country rocks, including many which could not have weathered into residual clays; on the other hand, they extend unbroken over tablelands and uplands in a way that excludes fluvial or lacustrine deposition.  On the ridges of the northern Barrier Range of western New South Wales for example, mantles of this type rest with abrupt unconcormity on little weathered sandstone, quartzite and dolomitic limestone alike (MABBUTT et al. 1973) ...  It is that windborne dust may have been trapped by the surface stone, which was then displaced upwards pari passu with accumulation, by relatively shallow wetting and drying as demonstrated experimentally.  Under this reasoning the existence of a rough stone pavement may have been a factor in the accumulation of the sediment now underlying it.
