A comprehension-based model of explorationThis paper describes LICAI, a model that simulates peforming tasks by exploration where the tasks are given to the user in the form of written exercises that contain no information about the correct action sequences. LICAI's comprehension processes and the action planning processes are based on Kintsch's construction-integration theory for text comprehension. The model comprehends the instructions and generates goals which are then stored in memory. The action planning process is controled by goals retrieved from memory cued by displays generated by the application. The model assumes that the instruction comprehension is a strategic process; instruction texts must be elaborated using specialized strategies that guide generation of goals. Representations of goals that lead to correct actions are restricted by the construction-integration architecture. The model predicts that successful exploration requires perfect matching of goal representation and the label on the correct object. The model is evaluated by comparing predictions with the results from a laboratory study. Finally, implications to designing instruction materials and interface displays that facilitate exploration are discussed.
