The Metaliteracy Learning Collaborative presented Advancing Metaliteracy in a Post-Truth World through the Design of a Global MOOC at SUNY’s Conference on Instruction & Technology at Purchase College on Wednesday, May 29 2019. Tom Mackey, Trudi Jacobson, Kelsey O’Brien, and Alena Rodick provided the first analysis of the Metaliteracy MOOC they created and facilitated as part of a top-tier SUNY Innovative Instruction Technology Grant (IITG) awarded in 2018. The Open edX MOOC Empowering Yourself in a Post-Truth is now available as a self-paced course and prepares learners across SUNY, as well as lifelong learners globally, to be empowered and responsible participants in rapidly changing social environments. This IITG project provided open resources for teachers and learners to grapple with the concerns of a post-truth society. The MOOC applied metaliteracy as a pedagogical framework to video content, interactive learning objects, and learning activities to promote collaborative metaliterate learning in reinventing a truthful world and rebuilding communities of trust.
