Distance learning involves a few computer and network technologies. Recent studies indicate that it is necessary to investigate the standards of contents, platforms, and communications for the use of distance education. In this paper, we discuss a few standards developed by different consortiums. We then focus on the discussion of Sharable Content Object Reference Model (SCORM), which is an asynchronous distance learning standard developed by the Advanced Distributed Learning (ADL) initiative. The SCORM specification include three parts: the Content Aggregation Model (CAM) which defines representations of course materials, the Run-Time Environment (RTE) which discusses communication protocols between course content and the server platform, and the simple sequence specification which controls interaction of users. We point out some important issues for the developers and researchers in the conclusion section.
