A comprehension-based model of explorationThe LInked model of Comprehension-based Action planning and Instruction taking (LICAI) simulates performing by exploration tasks using applications hosted on systems with graphical interfaces. The tasks are given to the user as written exercises that contain no information about the correct action sequences. LICAI's comprehension and action-planning processes are based on Kintsch's construction-integration theory for text comprehension. The model assumes that comprehending instructions is a strategic process; instruction texts must be elaborated using specialized strategies that guide goal generation. LICAI comprehends the instructions and generates goals which are then stored in memory. The action-planning processes are controlled by goals retrieved from memory. Representations of goals that can guide exploration are restricted by the construction-integration architecture. The model predicts that successful exploration requires linking of the goal representation with the label on the correct object. The model is evaluated by comparing its predictions with results from an experiment al study of learning by exploration by Franzke (1994, 1995). We discuss the implications of LICAI for designing instruction materials and interface s that facilitate exploration.
