About Us

A pedagogical research project is born at the University of Calgary to support first year courses. Interactive Linear Algebra on the Web (ILAW) offers multimedia lessons, interactive explorations, and formative online assignments. The resulting material provides students with tools to study and explore Linear Algebra, and receive personalized feedback on their homework problems similar to how traditional homework is marked by experienced instructors.
Lyryx Learning is created to support and make the material available to other institutions.
Lyryx branches into other subjects areas in Business & Economics. Partnering with McGraw-Hill Ryerson in Canada (now McGraw Hill Education) to provide sales channels for these new subject areas, Lyryx continues to focus on creating high quality interactive materials and online assessment products. By 2008, Lyryx was used by approximately 95,000 students and 1,100 instructors across Canada.
Lyryx continues to expand with several smaller publishers and other businesses in the United States and Canada, continuing to provide quality assessment solutions to partners' educational products. This includes one of the first textbook publishers whose products were based on Creative Commons open licenses.

Realizing the great potential in Open Educational Resources (OER), Lyryx aims at a sustainable business model and begins to engage authors of OER textbooks directly to create products and services under the new "Lyryx with Open Texts" brand name. While the textbook is provided to students at no cost, a fair license fee is charged for the use of the online assessment in exchange for user support, editorial services to adapt the content, and all other needed supplementary material. Print-on-demand copies are also available as a low cost option.

Instead of the traditional model of paying “royalties” to authors, a share of revenues from licensing is returned to authors in exchange for adapting their content to the needs of individual schools and creating the supplementary materials.

In the Fall 2016 semester alone, Lyryx is supporting over 10,000 students using OERs, up from 8,000 in Fall 2015. Lyryx continues to expand its library of open textbooks into both Business & Economics and Mathematics & Statistics areas, seeking authors in these and other subject areas as well.
