The Community of Inquiry (CoI) is a pedagogical model that supports digital teaching and learning: online, in-person, and blended. Education for contemporary, digital societies is a complex process that requires the design and delivery of a thoughtful interplay between the instructor, student interactions, and course resources. The Col framework gets at the heart of establishing and sustaining multi-modal educational experiences through the development of interdependent elements: social, cognitive, and teaching presence. // The Designing for Communities of Inquiry in Online Courses (DCOI) massive open online course (MOOC) will explore the why and how of using the Col as the basis for developing and teaching high quality online and blended courses. In this course, we highlight practical ways of helping students learn through active participation and shared sense-making. Current Col application issues related to shared metacognition, learning analytics, and artificial intelligence will also be explored in this highly engaging inquiry-based MOOC. // The Col provides a meaningful 21st century framework for digital education pedagogy. Educators, designers, and administrators will all benefit from taking this course to learn about the Col and how it supports learning, now and into the future.
