RET Site: The Great American Biotic Interchange (GABI)--The Panama Connection

点击翻译按钮获取中文摘要

This three-year project focuses on professional research experiences for middle and high school STEM teachers through investigations of the Great American Biotic Interchange (GABI). Each year 10 teachers (in diverse fields including biology, chemistry, earth and environmental sciences, and oceanography) and three to five professional paleontologists will participate in a four-phase process of professional development, including: a (1) pre-trip orientation (May); (2) 12 days in Panama in July collecting fossils from previously reported, as well as newly discovered, sites; (3) a post-trip on-line (cyber-enabled) Community of Practice; and (4) a final wrap-up at the end of each cohort (December). In addition, some of the teachers may also elect to partner with scientists in their research laboratories, principally located in California, Florida, and New Mexico. The partners in Panama are from the Universidad Autónoma de Chiriquí (UNACHI), including faculty and students, as well as STEM teachers from schools in Panama. Teachers that participate in this RET will develop lesson plans related to fossils, paleontology, evolution, geology, past climate change, and related content aligned with current STEM standards. The GABI, catalyzed by the formation of the Isthmus of Panama during the Neogene, had a profound effect on the evolution and geography of terrestrial organisms throughout the Americas and marine organisms globally. For example, more than 100 genera of terrestrial mammals dispersed between the Americas, and numerous marine organisms had their interoceanic distributions cut in half by the formation of the Isthmus. Rather than being considered a single event that occurred about 4 million years ago, the GABI likely represents a series of dispersals over the past 10 million years, some of which occurred before full closure of the Isthmus. New fossil discoveries in Panama resulting from the GABI RET (Research Experiences for Teachers) are thus contributing to the understanding of the complexity and timing of the GABI during the Neogene.This award is being co-funded with the Office International and Integrative Activities.
