But what about quality

But what about quality?


Open online homework and courses to support open textbooks

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

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 calculus stewart hoffman comparison

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%
