A Framework and System for Scenario-Based Instructional Design and Implementation

This paper describes a process model for designing and implementing instruction using various multimedia instructional materials. Our model takes a scenario-based approach as its central concept. It conceptualizes the whole process of evolving multimedia instructional material as a double-loop of activities in which teachers and students work together to enrich it. The external loop comprises planning, implementing, checking and evaluating instruction, whereas the internal loop is made up of its implementation, verification, and modification. We provide a formal definition of the scenario used in the double-loop model and illustrate an example of how scenarios are used in the model. We also explain our instruction system, which facilitates activities in the double-loop model. The evaluation of our instruction system shows that the use of IMPRESSION is acceptable in class room.
