The Hannah Arendt Summer Seminar for Schoolteachers is an NEH Seminar that offers stimulating dialogue for School Teachers (K-12) of all disciplines, including history, social studies, philosophy, literature, philosophy, and government. Given the varied responses to the recent election and the documented increase in incidents of hateful speech and other attacks on school campuses and in classrooms across the country, having a space to learn and practice how to engage difficult conversations on controversial subjects is needed now more than ever. Although the seminar emphasizes the analysis of history and political theory, it serves to foster community among school teachers and change-makers interested in practicing and encouraging critical thinking about contested political and ethical issues framed by what Hannah Arendt called “the human condition of plurality.”    The seminar will take place over the course of four weeks at UC Davis, June 25 through July 21, 2017. Successful applicants will be notified of their selection on Friday, March 31, 2017, and they will have until Friday, April 7 to accept or decline the offer. Deadline for application is March 1, 2017.

The Crow Canyon Archaeological Center is proud to present an extraordinary, tuition-free National Endowment for the Humanities Summer Institute program to help teachers explore the complex relationship between archaeology, history, and tribal identity. The program, "From Mesa Verde to Santa Fe: Pueblo Identity in the Southwest," examines more than 4,000 years of Pueblo Indian history from 2000 B.C. to the present, along with the many ways to explore and interpret that history—and the often complex relationship between history and Pueblo identity. Institute scholars will spend several days each at Mesa Verde National Park and in historic Pueblo and Spanish colonial communities in northern New Mexico, where they will piece together this little-told story through archaeology, ethnohistory, and oral history.
The program runs from June 25-July 15, 2017. Applications must be postmarked by March 1, 2017; and successful applicants will be notified of their selection on April 7, 2017. Each participant will receive a $2,700 stipend to help cover the cost of travel and living expenses, and up to six hours of graduate-level college credit is available through the Colorado School of Mines.
