Exemplary Teaching Activities

Initial Publication Date: November 8, 2019 | Fix Links: June 18, 2024 (see revision history: 2 events)

Beginning in 2011, On the Cutting Edge began a process to review the extensive collection of activities submitted by workshop participants and members of the geoscience community. With the transition of the On the Cutting Edge program into NAGT the review process is now being used to broadly review online teaching activities relevant to NAGT's community of Earth educators. Through this review processes activities are scored on 5 elements: scientific veracity; alignment of goals, activity, and assessment; pedagogical effectiveness; robustness; and completeness of the description. The activities that score very highly in these areas become part of the Cutting Edge Exemplary Collection and are featured below.

How Do We Know Where an Earthquake Originated? part of EarthScope ANGLE:Educational Materials:Activities
Jeffrey Barker (Binghamton University) & Michael Hubenthal (IRIS)
Students use real seismograms to determine the arrival times for P and S waves and use these times to determine the distance of the seismic station from the earthquake. Seismograms from three stations are provided to determine the epicenter using the S – P (S minus P) method. Because real seismograms contain some "noise" with resultant uncertainty in locating arrival times of P and S waves, this activity promotes appreciation for uncertainties in interpretation of real scientific data.

Unit 2.2 - Basic Critical Zone Concepts part of Critical Zone Science
Ashlee Dere, University of Nebraska at Omaha; Susan Gill, Stroud Water Research Center
Students will learn about geoscience-specific methods used to analyze data in the Critical Zone from data-driven activities and short presentations by their peers. The topics include the use of carbon isotopes, ...
