The Maryland Open Source Textbook (M.O.S.T.) initiative, led by the University System of Maryland’s William E. Kirwan Center for Academic Innovation, is .seeking proposals for its 2018 High-impact OER Mini-Grant program to strategically support Maryland public institutions’ efforts to adopt Open Educational Resources (OERs) as a means to greatly reduce textbook costs and address college affordability for students. Building on the prior success of the M.O.S.T. initiative and the first round of mini-grants, this funding program will target OER adoption in “high impact,” high enrollment courses for which high-quality OER already exists. Two types of mini-grants will be awarded: 1) Adopt/Adapt OER ($500 - $1,500) and 2) Scaling OER ($1,500 - $2,500).
