Abstract
MOOCs, or massive open online classes have reached hundreds of millions of people around the world in the past decade with a model of free open access learning. They are an excellent vehicle for delivering science to lifelong learners. Building on experience in designing astronomy MOOCs for Udemy and Coursera, we have created an astrobiology MOOC for Coursera called “Astrobiology: Exploring Other Worlds” that launched in April 2019. As of early 2022, about 9000 people have started the course, and nearly 10% of those have completed it. The average user rating is 4.9 out of 5. The core content is 10 h of video lectures, divided into six modules, which cover the possibilities of life in the Solar System, the search for exoplanets, the concept of habitability, the definition of life and basics of biology, evolution of life on Earth, and the search for extraterrestrial intelligence. Pedagogy was designed around clear learning objectives and includes quizzes, writing assignments, and a final project that draws on all the concepts presented in the course where students design their own mission to characterize exoplanets. In this study, we describe the design, implementation, and subsequent success of our 2019 astrobiology MOOC.
