Dear Colleagues, We hope you'll consider submitting an abstract to the following session at AGU: Session ED037: Teaching About Time Understanding geologic time and rates of processes are central to many geoscience, biology, and planetary science fields, yet understanding these concepts is challenging for students. These challenges aries from a variety of factors including having no intuitive feel for large numbers, our everyday view of the world as unchanging, and the need to infer a history that integrates short periods of high impact activity, long periods of low impact activity, and periods of no or destructive activity. This session solicits research from geo- bio- and planetary science education and the cognitive sciences that can be applied to help educators teach and assess an understanding of geologic and astronomic time. Abstracts are due on August 8. Thanks, and we look forward to seeing you at AGU!
