At the University of Denver, for University College, in the Department of Geography:
In early January, 1999, I was drafted on two days notice to start teaching graduate courses in remote sensing and image processing at the University of Denver. I had not been seeking such a task but the previous instructors had dropped out because of the workload at their regular jobs. So I became an adjunct professor. The course names, titles, durations, and credit hours have changed over the past years. Eventually there were two classes being taught, in the classroom in the winter and spring quarters, and "online" in all quarters. I supplied all students with a DVD containing lectures, data, homework assignments, and free software. The students had to buy the textbook but it was the same for both courses. Homework assignments were submitted by email for the online classes and either directly or by email for the classroom sessions. Later the university used the eCollege and Canvas systems for online instruction, and students could alternatively use those for study and homework submissions. After the Winter Quarter of 2016 a younger instructor was found to teach the courses.

10-week courses, 4 credit hours:
GIS 4700 Remote Sensing
GIS 4740 Digital Image Processing

At Webster University, Denver campus:
In 2004 I was requested to prepare a satellite remote sensing course at the graduate level for Webster University. The classes started in the summer quarter of 2005 and are 9 weeks long for 3 credit hours. They have been taught at the Denver campus near Arapahoe and I-25, and at Buckley AFB. Structure is similar to those at the University of Denver. The course title, SPSM 5990 Issues in Space Operations, allows a variety of subjects to be taught. My content has been satellite remote sensing, and in the Summer of 2009 another instructor used different content. A course of the same content as mine, SPSM 5300, was advertized for a few years but never attracted enough students to avoid cancellation.

9-week course, 3 credit hours:
SPSM 5990 Issues in Space Operations

At Peking University, Beijing, China
For the 4 weeks of July, 2017, I was invited through ERRC (Educational Resources and Referrals - China; www.errchina.com) to teach a science course titled "Selected Readings on Frontiers of Science and Technology" to 58 undergraduate students. A summary is in the folder /TripReports/2017 China/.

At University of Monastir, Tunisia, North Africa
For 2 weeks of July, 2023, I coached about 55 graduate students, Ph.D. science candidates, in their use of English in their scientific reports and theses destined for publication. I provided corrections for three manuscripts. A summary is in the folder /TripReports/2023Tunisia/.
