Under the Kaleidoscope grant, we developed and piloted Intermediate Algebra in Spring 2012. By Fall 2013 we had success rates up to 83% and retention rates (same-semester persistence) up to 69%. In Spring 2014, implementation was scaled up to all Intermediate Algebra sections at TC3, with overall success 53% (from mid 30s). We now offer College Algebra and Precalculus in OER. Up to Spring 2016, 1721 students have used OER in their math course, and have saved between $206,000 and $277,260 with completion and retention rates increase of more than 40%.
