    From the above comments, maybe the Sequencing Workgroup should be called Orchestration.

    How about such clarification?

    Composition is putting (content) things together by an Instructional Designer. It is more than Aggregation.

    Self-Learning is playing back pre-composed (content) things by a Student. It is more than just a Navigation.

    Orchestration is playing back pre-composed (content) things for the student by the instructor. It is more than just a Sequencing.

    Choreography is letting (content) things to dance/play back for the student by their own without external orchestration. It is more than sequencing.

    Does it make any sense?

    Thanks

    Hi Vlad,

    I think we are intending orchestration to refer to the putting things together (by anyone), rather than to play-back.

    As for self-learning, I know that this was thrown at SCORM as a criticism that it was too focused on single-student learning. I would want to aim for types of play-back which delivered e.g. collaborative learning activities.

    I agree that "navigation" has taken on quite a narrow focus under SCORM 2004 to refer to actions initiated by the student by clicking buttons. I think that we are at a stage when all this vocabulary is up for review - but I suspect that any consensus will emerge slowly!

    One word we are definitely on the hunt for is a term to refer to the reusable, autonomous instructional object... any suggestions?

    Best, Crispin.

      Crispin,

      How about adding a choreography in our vocabulary?

      As you know in orchestration, which is usually used in private business processes, a central process takes control of the involved services and coordinates the execution of different operations on the services involved in the operation. The involved services do not "know" (and do not need to know) that they are involved in a composition process and that they are taking part in a higher-level business process. Only the central coordinator of the orchestration is aware of this goal, so the orchestration is centralized with explicit definitions of operations and the order of invocation of services. 

      Choreography, in contrast, does not rely on a central coordinator. Rather, each service involved in the choreography knows exactly when to execute its operations and with whom to interact. Choreography is a collaborative effort focusing on the exchange of messages in public processes. All participants in the choreography need to be aware of the business process, operations to execute, messages to exchange, and the timing of message exchanges.  

      I took these descriptions from the Business Processes Modeling field, but both make sense in eLearning field.

      I hope it will help us not to limit our vision for the sake of our standard users.

      Crispin,

      I like your "Autonomous Instructional Object". AIO sounds good.

      1) The term Instructional Object has already been introduced in DITA in relation with other objects: Infromation Object and Learning Object.

      2) Many participants of SCORM 2.0 were not happy with existing SCO and expressed interest in something better such as a lesson, which may be AIO.

      3) I see the AIO as a container, which may include all other objects: information object, learning object, assessment object, ..., and AIO again. The same general framework of AIO may be used to define all other more simple objects as a part of AIO, which will assure quality of composition and orchestration.

      4) AIO will mean All-In-One.

      Does it make sense?

      Vlad
