Key principles are student centeredness and a focus on learning rather than teaching.
The following sections describe the elements that comprise the integrated whole. The written course texts, the written supplementary material, video and audio recordings, course website, computer software, textbooks, and other materials are delivered direct to each and every student either by mail or electronically. The core of most courses is a set of specially written course texts. These course texts are delivered to the student and become the property of the student. In addition to the printed course texts, there will usually be supplementary written material such as study guides, video or audio notes, which will normally be posted on the course website.
