A COMPREHENSION-BASED MODEL OF EXPLORATION

The linked model of comprehension-based action planning and instructio n taking (LICAI) simulates performing by exploration tasks using appli cations hosted on systems with graphical user interfaces. The tasks ar e given to the user as written exercises containing no information abo ut the correct action sequences. LICAI's comprehension and action-plan ning processes are based on Kintsch's construction-integration (C-I) t heory for text comprehension. The model assumes that comprehending ins tructions is a strategic process; instruction texts must be elaborated using specialized strategies that guide goal generation. LICAI compre hends the instructions and generates goals that are then stored in mem ory. The action-planning processes are controlled by goals retrieved f rom memory. Representations of goals that can guide exploration are re stricted by the C-I architecture. The model predicts that successful e xploration requires linking of the goal representation with the label on the correct object. The model is evaluated by comparing its predict ions with results from an experimental study of learning by exploratio n by Franzke (1994, 1995). We discuss the implications of LICAI for de signing instruction materials and interfaces that facilitate explorati on.
