> Free online textbooks work Work? Being no worse than commercial textbooks can be a surprisingly low bar. "[A]ligned to state standards and created by well-known subject-matter experts and master teachers" is regrettably far from sufficient to avoid being really really bad. OER authorship processes and incentives seem regrettably similar to those of closed textbooks. Especially around correctness. Even the few which manage an online errata/issue database can still struggle because of culture and incentives. Eg, "Ok, we'll tweak that wording so it's "not wrong"", rather than crafting a much harder real fix, despite no hope that students won't be left harmed. Anyone know of any efforts somewhere getting this right? So for instance, openstax and Utah Open Text (two projects in comments here) have astronomy texts, which like the most popular commercial intro astronomy college textbooks, teach the Sun as yellow. Another place this conception shows up, is on astronomy education research's lists of common misconceptions in astronomy education. :/ Conversations with even first-tier astronomy graduate students can go "What color is the Sun? Yellow. Sunlight? White... wait.. err... that doesn't make sense, does it?" Incompatible conceptions, perhaps first learned in kindergarten, persisting unintegrated into graduate school. Persisting with repeated reinforcement. Because the incentives around textbook correctness, let alone around transferable understanding, are just that severely dysfunctional. Even Wikipedia has been managing to more-or-less get this one right for a few years now. But not textbooks. And not OER textbooks. The OER bit seems like it could help, by enabling different processes and incentives, but... not just yet. I'd like to suggest there's an untapped market and opportunity for disruption... but what might that look like?
