A pedagogical scenario or learning scenario is an instantiation of an instructional design model for a given subject and a given kind of situation. It basically defines what learners and other actors like the teacher should/can do with a given set of resources and tools. A more formal scenario can be called a learning design.
See also the category example cases. The distinction between an (abstract) scenario and a concrete example cases is not always easy in the literature, given that published example cases try to generalize...

Here is a small list of typical ingredients one can find in a scenario
Note: some courseware integrates learning activities, e.g. hypermodels or e-learning environments based on IMS Learning Design
Schulmeister (2005:487-488) suggest to define scenarios according to 3 dimensions:
The definition of what a pedagogical scenario is can differ a lot in various schools of thought based on different Learning theories, pedagogical theories etc. There are very contrasting instructional design models and ideas on pedagogic strategy.
Modern pedagogical theory (whether behaviorist, cognitivist, constructivist etc. ) insists on the importance of scenarios, i.e. story-boards that define learning activities.
Certain kinds of learning objects include pedagogical designs, e.g. IMS Learning Design, LAMS modules, Emergent Learning Objects.
Currently (20009) the most well known formal scenario specification and execution language is IMS Learning Design. It implements the following basic learning design model:
ROLE -> performs -> ACTIVITIES -> within -> an ENVRIONMENT
