Many of the largest OER projects funded over the past fifteen years targeted high cost, high impact courses to save students money. Because of this, most of the OER available today are for general education courses such as Psychology, Biology, and Calculus. This does not mean that there are no OER available for specialized subject areas or graduate-level courses; however, there are more resources to choose from for instructors who teach Introduction to Psychology than for those who teach Electronic Systems Integration for Agricultural Machinery & Production Systems. Note: This is beginning to change as more institutions begin publishing OER through regional and institutional grant programs.
