Open online homework and courses to support open textbooks

David Lippman

Pierce College Ft. Steilacoom


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


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)


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


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


Lecture outlines, with examples


But what about quality?


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.


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

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


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+


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%


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
