Massive open online courses (MOOCs) have been on the forefront of current conversations about teaching and learning in the 21st century. The ability for participants at all levels to take free courses in hundreds of topics ranging from guitar to nuclear physics has created as many opportunities as it has challenges and questions. For the most part, the topics and the conversations have focused on professional development and post-secondary education; MOOCs may end up changing how we teach and learn at the graduate and undergraduate levels. However, MOOCs are also now being implemented in K–12 environments. There are several ways in which MOOCs in their current formats can be used by K–12 students and teachers. There are also several benefits from K–12 educators considering the definitions of MOOCs and the concepts they present. This paper presents a conversation about the potential value of MOOCs in K–12 teaching and learning.
