In March of 2010, UNAVCO Education and Outreach staff and collaborators held a workshop to help college-level teachers incorporate geodesy and new teaching techniques into their courses. Teaching Geodesy in the 21st Century - An On the Cutting Edge - UNAVCO Workshop, drew sixteen enthusiastic and engaged professors, teachers, a post doc, and graduate student from around the country to Boulder, CO (Fig. 1). Workshop conveners included Susan Eriksson, UNAVCO; Valerie Sloan, UNAVCO; Barb Tewksbury, Hamilton College; Shimon Wdowinski, University of Miami. Learn more about their contributions below. And be sure to stay tuned for upcoming workshops at UNAVCO Educational Workshops.
Geodesy in the 21st Century - Shimon Wdowinsky introduced different geodetic methods and applications such as:
Using Data in Large Classes – Anne Sheehan led the group through an exercise of mapping velocity vectors across the San Andreas Fault using PBO GPS data.
Giving Interactive Lectures – Val Sloan presented some ways of engaging students:
Assessing Authentic Learning – Susan Eriksson inspired us on how assessment promotes learning and informs teaching, especially when goals, assignments, and assessments are aligned. She presented a variety of types of assessment tools beyond traditional ones, including:
Rolling up Their Sleeves, participants evaluated and critiqued two UNAVCO worksheets (presented by Shelley Olds and Valerie Sloan), providing incisive insight on how to improve them. Then, breaking into groups of three or four, participants took turns evaluating each other’s assignments and discussing potential improvements. In the process, participants were able to find out who might be good contacts for learning more about geodesy in their content area, and so some valuable networking was accomplished.
After spending some time individually working on a plan for modifying their own assignment, the group reconvened and discussed which geodetic concepts they thought are the most important to include in introductory geosciences courses (See Finished Actictivies posted on the On the Cutting Edge - UNAVCO workshop website).
This workshop was one of the On the Cutting Edge Follow-on workshops which are designed to disseminate themes and outcomes from a larger workshop. This workshop was part of the On the Cutting Edge professional development programhttp://serc.carleton.edu/NAGTWorkshops/index.html for current and future geoscience faculty, and was sponsored by the National Association of Geoscience Teachers with funding provided by a grant from the National Science Foundation - Division of Undergraduate Education.
