After months of writing and wrangling, we are very happy to open up the first draft chapter of our textbook for open community review: “Open Education & Science“. From now on, we invite scholars and practitioners interested in these two closely related topics to comment on the first version of our manuscript. While working on further chapters, we will engage regularly with these comments and follow suggestions where they seem to fit the overall goal of our project. We understand this process as highly experimental: We have no idea if and how many people are interested in contributing to this textbook-in-progress. Also, we haven’t entirely figured out a routine on how to deal with comments and how to engage with commentators. Hopefully we know more about this in a few weeks time.
