This article reports on a study conducted on a pilot program using open educational resources (OER) and the first half described the modest gains in achievement OER can produce. But the second part emphasizes the cost. "Creating an OER degree pathway cost between $300,000 and $1 million at five of the community colleges... The biggest expense came from developing courses. STEM classes and those that used open interactive learning systems were the costliest to develop." This to me indicates the degree that publishers have insinuated themselves into the teaching process. When I taught courses (including computer courses) developing the course was part of the normal duties of an instructor. But over time, it has come to be treated as an additional expense (for which, of course, the student would be charged).
