We have long been engaged in providing professional learning opportunities for educators, including K-12 teachers, school and district leaders, college of education faculty, and state department of education staff. Our work over two decades has led us to continuously explore variations of face-to-face, online, and blended professional learning experiences as both the available technologies and the technological fluency of our audiences advanced. The advent of MOOCs has led us to consider their potential to help education professionals advance their expertise and improve their professional practices. This chapter describes the first year of our efforts, the design principles underlying our work, lessons learned, and future directions of what we call MOOC-Eds-Massive Open Online Courses for Educators.
