Metaliteracy is examined as a comprehensive framework to develop learners as informed consumers and active producers of information in collaborative communities of trust. In today's post-truth society, personal and political beliefs have often diminished the meaning and impact of truth and objective reasoning. Metaliteracy prepares reflective learners to responsibly consume and ethically produce information in participatory social environments. As civic-minded citizens, metaliterate learners take control of their learning while mindfully participating in cooperative and productive communities. The innovative Massive Open Online Course (MOOC), "Empowering Yourself in a Post-Truth World," is analyzed as part of this pedagogical strategy to prepare learners for the challenges of a post-truth society.
