In each of the courses below you will find exemplar units. These units have gone through an extensive creation/revision process and have been evaluated and modified using the Course Design Guide (found under OBC Resources). These units have incorporated all four anchors of the OBC. For the other units in the course, you will find materials to support a blended environment, but not to the level of content and organization found in the exemplar units. OBC Courses are continually being updated and modified to enhance the content. You will have direct access to these updates as they happen.
