Using WebCT, Kresge Library (KL) at Oakland University (OU) first developed an online module to augment the faceto- face instruction conducted with each section of OU’s basic writing class, Rhetoric 160 (RHT 160). As OU has transitioned from WebCT to Moodle, library faculty members have increased KL’s presence by creating a standalone module that appears alongside each student’s RHT 160 class in Moodle. Librarians have also created both fullyonline courses & supplemental, discipline-specific content for other classes using Moodle. This presentation reports on the evolution of KL’s LMS presence and discusses obstacles and successes in teaching in this online environment. Select results will be shared from several studies that KL librarians have conducted to assess Web-based instruction efforts.
