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

23 But what about quality?

24 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.

25 There’s no reason to use any proxy for quality when we can look at student success directly.

26 Mercy College - (Wallace Algebra) Percentage passing with C or better Fall 2011 No OER Fall 2012 OER Spring 2011 No OER Spring 2013 OER Total No OER Total OER n=2,842 including pilot

27 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

28 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+

29 Success Data - Calculus Stewart/Hoffman Comparison 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 Bellevue College used Stewart (2006-07) and Hoffman (2007-08) Stewart N=622 Success = “ABC” = 74.4% Success range: 42 – 90% Hoffman N=710 Success = “ABC” = 74.8% Success range: 40 – 95%

30 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
