 When Stanford joined the Sakai Project's joint development effort to create a widely adopted, open source, CMS in 2004, effort was redirected to that project.Functionality of the original CourseWork assignment tool strongly influenced the design of the SAMigo Test and Quiz tool, a part of the Sakai tool suite.In early winter 1988 the Stanford Learning Lab initiated development on CourseWork, a web-based problem set tool for use in the Human Biology Program at Stanford University.
