Beyond the specific ID modeling agents available such as LAMS or Reload, it is an interesting observation that the teaching delivery tool (VLE) mixed with human code determines the shared vocabulary of academic staff. A comparable analogy among motorists would be the code in use by truck drivers being different to that of Formula 1 drivers. Though both professions perform closely related activities, the technology and environment determines the vocabulary.
This led me to the conclusion that while there may be a limited number of baseline notations such as IMS-LD XML structures, there are an infinite number of possible user-facing modeling agents, ranging from the very simple to the very complex and detailed. The challenge is to find the right human code, vocabularies and concepts that teaching staff can relate to, allowing human interactions with designs, both in creating and communicating.
