  1. Open online homework and courses to support open textbooks

    David Lippman Pierce College Ft. Steilacoom
  2. The Problem Many colleges rely on online homework and pre-packaged materials This can pose a barrier to adoption of open textbooks Especially hard for courses mostly taught by adjuncts or TAs
  3. IMathAS / MyOpenMath IMathAS is an open-source online homework and learning management platform for math Algorithmic questions, auto-grading of algebraic answers Tens of thousands of questions created by faculty ranging from arithmetic through differential equations Full learning management system (LMS)
  4. Open Courses Courses that combine and align open textbooks, videos, and online assessment Some contain additional resources Courses created by Open Course Library Project Kaleidoscope Project Individual faculty Refined by users
  5. Existing Courses Arithmetic & Prealgebra (dev) Beginning & Intermediate Algebra (dev) College Algebra / Precalculus (2 versions) Trigonometry Calculus (single variable) Business Calculus Math for Liberal Arts / Quantitative Reasoning
  6. Lecture outlines, with examples
  7. But what about quality?
  8. MAA Review by Mike Kenyon, Green River Community College, 10/15/2012 We considered about two dozen texts in our adoption process […] Once the finalists were selected, it became clear that the Lippman/Rasmussen text was equal or superior to the others in quality and far outpaced them in cost. The vote of our full-time faculty was, in fact, unanimous.
  9. There’s no reason to use any proxy for quality when we can look at student success directly.
  10. Mercy College - (Wallace Algebra)Percentage passing with C or better Total No OER Total OER Fall 2011 No OER Fall 2012 OER Spring 2011 No OER Spring 2013 OER n=2,842 including pilot
  11. Results – Math for Lib Arts Commercial text + Blackboard (‘06-’08 data) 70.2% pass rate, n = 131 IMathAS + Open Text v1 (‘08-’11 data) 72.4% pass rate, n = 236 IMathAS + Open Text v2 (’12-’13 data) 80.4% pass rate, n = 92 *No statistically significant difference
  12. Student Success Data - Precalc 4850 students at Pierce, Green River, and Shoreline have used our text (over the last 2 years), vs. 5000 past students saw no significant difference in success, while saving $300,000+
  13. Success Data - CalculusStewart/Hoffman Comparison Bellevue College used Stewart (2006-07) and Hoffman (2007-08) Five instructors taught multiple sections in 2006-07 using Stewart and then multiple sections in 2007-08 using Hoffman. The student success numbers for these five instructors were virtually identical using each text, but 4 of the 5 had slightly greater student success using Hoffman Stewart N=622 Success = “ABC” = 74.4% Success range: 42 – 90% Hoffman N=710 Success = “ABC” = 74.8% Success range: 40 – 95%
  14. Using These Courses MyOpenMath.com is a free*-to-use installation of IMathAS, focused on courses aligned with open textbooks. IMathAS is open-source software that can be run on almost any web server. * Support is an optional paid add-on
