I have used Sakai now at two organizations, American Public University (APUS), an online for profit university and Texas State University, a large campus state university. At American Public University Sakai was the main online Learning Management system. It was utilized across the organization as the main tool and engine for students and faculty as the online learning system for the university. At Texas State, Sakai is used on a more selective and limited scale. Here, it is used for a smaller cohort of online classes but it is also used as a support (resource) system for hybrid courses. Sakai addresses the business problem of 'online classroom' management. Essentially, the system can build an infrastructure for faculty and students for learning. For faculty, it provides an infrastructure system for say a semester 'course' arcs and online learning infrastructures. For students, it is the main online system for receiving assignments, taking tests, dialoguing through forums with other students etc.
