Contemplating 400 Years of Inequality

Contemplating 400 Years of Inequality

The November 2019 ACMHE Webinar, presented by Angel Acosta
Doctoral student in the Curriculum and Teaching Department at Teachers College, Columbia University
Originally broadcast live on Wednesday, November 20, 2019
Free and open to all, with $10 optional, suggested donation

Join us for a webinar exploring the use of a powerful tool for contemplating the last 400 years of U.S. history. Angel Acosta will discuss how using a 4ft x 20ft timeline as a contemplative learning tool supports participants with deepening their understanding of entrenched racial and socio-economic inequality in the United States. With the aim of commemorating the year 1619–marking the arrival of enslaved Africans to U.S. shores–the 400 Years of Inequality National Organizing Committee has created a timeline for all of us to use to dive into our past. Angel will share how combining contemplative-based practices with the exploration of the timeline has helped to guide communities in re-imagining how we can both transcend implicit bias and develop a more compassionate society. This webinar will give participants access to the instructions for printing the timeline and resources for integrating it into educational settings.

    I am so blessed to have found this link! The timeline is a deeply important contribution to all movements to for social justice. I am here looking for resources for my workplace (a nonprofit health and social services organization) which is reckoning with it’s own racist structures and how to transform into an anti-racist organization and authentic Beloved Community.
