This is the project about our experiences and some descriptive statistics from a Massive Online Open Course (MOOC) named Sustainable and Accessible Science Education (SASE). In terms of educational literature, sustainability and accessibility are two important terms. Sustainability highlights the continuity of time. Life-long learning is well known explanation of this continuity. The other word “accessibility” emphasize that what we need to do to make education available “for all”. Out of time (sustainability) and population (accessibility), the third part of title; “science education” underlines the content. In the MOOC we criticize and analyze Technology, Society, and Environment in terms of these three dimensions. The course was in Turkish and from 25 different cities, 111 participant enrolled in SASE. Only ten of them got more than 55 point from 100 point and qualified a certificate. The MOOC is completed within eight weeks. This MOOC from AtademiX platform includes reading articles, YouTube videos, live lessons, some interviews with experts, and Self-evaluation questions. With this project we aim to introduce principles of how to provide and protect a sustainable and accessible science education by the help of completed and mentioned MOOC.
