Learning technology standards are increasingly gaining importance in the field of Web-based teaching. At present, two standards dominating the market are taking shape. These are the AICC (Aviation Industry Computer Based Training Committee) standard of the AICC organization and the SCORM (Sharable Content Object Reference Model) standard of the ADL (Advanced Distributed Learning) initiative. At present, only the AICC standard can be certified; however, in the near future, the SCORM standard will be certifiable as well. Based on the AICC and LOM (Learning Object Metadata) metadata standards, the SCORM standard stands the chance to become the standard dominating the market. A number of restrictions are involved with the standards, however. This paper examines general deficiencies of the standards mentioned, as well as the problems resulting from their applications to learning management systems. (Author)
