Abstract
We analyze the efficiency and effectiveness of task choice in the context of a reading tutor that listens to children read aloud. We define efficiency as the time to pick a story, and effectiveness in terms of exposing students to new material. We describe design features we added to improve the Reading Tutor? efficiency and effectiveness, and evaluate the resulting systems quantitatively, as follows. First, we made the story menu child-friendlier by incorporating two improvements: (a) to support use by nonreaders, the new menu spoke all items on the list; (b) to speed up choice, the new menu required just one click to select an item. Second, we instituted a mixed-initiative story choice policy where the Reading Tutor and the student took turns choosing stories. These improvements made story choice measurably more efficient and effective.
