CLAS Sustainability Learning Community   - Partnering with Prof. Peter Goggin, Librarian Katherine O'Clair, English TAs April Brannon and Steven Accardi, and Geography TAs Gabe Judkins and Elyssa Gutbrod, I served as the lead faculty in this Fall Semester learning community. Although there was supposed to be a course-load reduction, my course load actually increased from two to three courses in order to meet programmatic needs.  The community lasted for two fall semesters in 2006 and 2007, with a break in the Fall of 2008 because of Professor Goggin’s sabbatical. Resumption in the Fall of 2009 was not possible.  Please feel free to examine some of the photos taken during field trips (for example, Salt River Trip Photos and Landside Trip Photos).

Development of GPH 211 as Online Lab Science Class – At the behest of the Provost, CLAS was tasked with the development of completely online lab science courses.  The stated goal was to help graduation rates for students whose life paths had forced them to move away from ASU, but who were just missing a few courses needed for graduation.  Another stated goal was to allow online degrees.  In turn, CLAS approached my academic unit to develop an online version of Introduction to Physical Geography (GPH 111).  In its stead, I coordinated an effort to turn our Introduction to Landform Processes (GPH 211) course into an online lab format that meets the Natural Science Quantitative (SQ) general studies criteria.  A pilot version of this course was taught in the Fall of 2008 and a 140-enrollment version is being taught currently in the Fall of 2009.  This effort absorbed (and continues to take) a tremendous amount of time rethinking every aspect of instruction, essentially turning the traditional SQ model upside down in order to maximize active learning of SQ criteria.

Development of an entirely Online Masters Degree in CLAS for Teachers – My outreach service to the K-12 teachers of Arizona, as a co-coordinator of the Arizona Geographic Alliance (http://alliance.la.asu.edu/azga/), led me to the realization that a Masters degree would benefit Arizona’s geography teachers.  Surveys revealed a strong preference for an online format, whereby professor-developed courses in geography content could be graded and mentored in coordination with retired master teachers.  This is a program now run during Summer and Winter Sessions in order to best match the schedules of practicing teachers.
This model, approved by ABOR, is to create a cycle of professional development.  Stage 1 is pre-service teachers learning about how to teach geography.  This first stage is implemented through a new course model for the training of future geography teachers described below. Stage 2 is where new teachers join the Arizona Geographic Alliance and gain more experience.  Stage 3 is where teachers obtain their Master of Advanced Study in Geographic Education (MASGE), CLAS degree with 2 courses taught by collaborators in ASUs Colleges of Education. Stage 4 is where alumni of this program go on to be Faculty Associates who grade assignments in the courses and mentor new teachers through this professional growth.  As the program’s director, I continue to refine content and aid Faculty Associates.  I coordinated the development of this program with many colleagues.   A paper, written with the first associate director of the MASGE that describes the degree in greater detail, can be viewed at this web address: http://alliance.la.asu.edu/dorn/MASGE_CalifGeog_08.pdf.

Learning Outcomes Assessment Coordinator – I volunteer as the “go to” individual in the writing and implementation of the learning outcome plans in my school.  These assessment plans are required by ASUs Office of University Evaluation.

Development of New Course Model for Training Pre-service Instruction in the Teaching of Geography – I developed and continue to improve GCU 414 (Teaching Geography Standards) as an online course to assist in the preparation of K-12 pre-service teachers.  This “Geography Methods” course is unique in its online format, its use of an extensive collection of best practices videos of master teachers explaining how they teach, and its connecting the realities of classroom instruction with pedagogical theory learned in classes in ASUs colleges of education.  The course was designed in way that it could be “turned over” to Faculty Associates (practicing or retired teachers), who have been the formal instructors of record starting in the Fall of 2006.  The course continues in this fiscal climate, because instruction now occurs during summer sessions.

Coordinator of GPH 111 Labs – Introduction to Physical Geography (GPH 111) is one of the largest enrollment courses in my academic unit, because it fulfills the SQ Natural Laboratory Science requirement.  I volunteer, without the normal course load reduction applied in many academic units, as the individual who works with the teaching assistants to monitor and improve the laboratory experiences of our students.

Notable Student Mentoring – My greatest satisfaction comes from mentoring students.  This mentoring occurs in three contexts. 
       First, I love helping undergraduates grow as scholars through the research process, taking them from freshmen to published authors.  I particularly enjoy working with brilliant students who, for one reason or another, fell through the cracks in high school and question their own ability for academic success. Space restrictions prevent a full listing of all undergraduates mentored.  The latest published honors students’ paper, first authored by Honors alumni Richard Stumpf II, can be seen here:  http://alliance.la.asu.edu/dorn/StumpfLearningVirtually2008.pdf.
       Second, I mentor graduate students in geography, most commonly Ph.D. students who are seeking employment as a college teacher.  It is a point of great pride for me that every single Ph.D. student has obtained academic employment at their preferred level.  These graduates and their first positions are listed below
        Third, I am currently mentor over 30 teachers seeking a graduate degree in geographic education in the program described above.  Rather than requiring a thesis, the capstone project requires that teachers embrace the scholarly literature in geography and link that literature to scholarly pedagogy.  As I write, I am working with the second and third cohorts Master of Advanced Study in Geographic Education students on their applied projects.
