About This Course

This course presents topics including functions, graphing and modeling with linear equations, systems of linear equations and inequalities, polynomials, factoring, rational expressions and equations, radicals, quadratics, inverses, exponential, and logarithmic functions. The course is designed to prepare students for success in college algebra or pre-calculus. With an OER text, aligned OER videos, and complete assessments, this title is a great low-cost alternative to traditional publisher materials.

Intermediate Algebra by Lumen Learning is a remix of MITE’s Developmental Math: An Open Program, College Algebra from OpenStax, and other widely-used OER texts. It was updated in August 2019 to improve the assessment question alignment to learning outcomes, eliminate typos and math rendering errors, and revise the text so that it better addresses some of the more complex concepts.

This version of the text was adapted by Salt Lake Community College in 2024 to meet the particular needs of the Intermediate Algebra curriculum for the college. The primary focus was to remove some of the overlap from a Beginning Algebra course, as well as increase the overall level of rigor and depth of coverage of the material essential to an Intermediate Algebra course.

Course Improvements

We believe in making continuous improvements to our courses in order to enhance and facilitate student learning. This newest version of the course includes a vast number of data-driven improvements to assessment questions and text content in order to better illustrate, clarify, and evaluate concepts.

About Lumen

Lumen Learning courseware is based on open educational resources (OER). When we can find well designed, effective OER that are appropriately licensed, we use them in our courseware. When we can’t find pre-existing OER, we create original content and license it as OER (under a Creative Commons Attribution license).

Lumen’s authoring process doesn’t end when our courseware is released. Our choice to adopt open educational resources means that we have the copyright permissions necessary to engage in continuous improvement of our learning content. Consequently, our courses are continually being revised and updated. Errata reported for our courseware are fixed in a matter of days, as opposed to the traditional model in which errors persist until the next “edition” is printed (often a year or more). Students and faculty can suggest improvements to our courses directly from within the courseware as they use it. And we conduct regular analyses to determine where students are struggling the most in our courseware, and make improvements that specifically target these areas.

Given our unique approach, our list of authors and other contributors may look different than the lists you are used to seeing. We provide both a list of the primary content authors (the people involved in the initial creation of the course) and a list of everyone who has contributed suggestions and other improvements to the course since it was first released. We invite you to join us as we create courseware that supports student learning more effectively each semester.
