IMS Learning Design - Summary
|IMS LD is a language in which to describe learning processes. It helps educational developers model who does what, when and with which content and services in order to achieve learning objectives.
The core concept of the Learning Design Specification is that regardless of pedagogical approach, a person gets a role in the teaching-learning process, typically a learner or a staff role. In this role he or she works toward certain outcomes by performing more or less structured learning and/or support activities within an environment. The environment consists of the appropriate learning objects and services to be used during the performance of the activities. Which role gets which activities at what moment in the process, is determined by the method or by a notification. Note: most of the concepts mentioned above are reflected in the information model, but some only exist at the conceptual level (person, outcome).
|Levels of Implementation and Compliance
To facilitate both the production of the specification and its subsequent implementation, IMS LD has been divided into three parts, known as Level A, Level B, and Level C. Separate XML schemas are provided for each level, with Levels B and C each integrating with and extending the previous level.
- Learning Design Level A contains the bulk of the IMS LD constructs, including activities, environments, plays, acts, roles, services, etc.
- Learning Design Level B adds Properties and Conditions to level A, which enable personalization and more elaborate sequencing and interactions based on learner portfolios. It can be used to direct the learning activities as well as record outcomes.
- Learning Design Level C adds Notification to level B. A notification is triggered by an outcome and can make a new activity available for a role to perform.
This information model describes a model for learning design that contains three primary components:
- A conceptual model that presents the vocabulary, the functional relationships between the concepts, and the relationship with IMS Content Packaging. The conceptual model is described from an overall (level C) perspective.
- An information model that describes the IMS LD elements for respectively the levels A, B, and C. Also the restricted conceptual model for the different levels is presented.
- A behavioral model which describes a set of runtime behaviors that delivery systems must implement.
