Improving the efficiency of dialogue in tutoring

The current studies investigated the efficient use of dialogue in intelligent tutoring systems that use natural language interaction. Such dialogues can be relatively time-consuming. This work addresses the question of how much dialogue is needed to produce significant learning gains. In Experiment 1, a full dialogue condition and a read-only control condition were compared with a mixed dialogue condition in which students engaged in full dialogue for half the problems followed by problems requiring only a limited engagement. We found that the mixed dialogue condition produced results as impressive as the full dialogue condition and took less time. Experiment 2 replicated these findings and further examined issues of time engaged in learning, quality of instruction, and learning gains. Overall, these results show that dialogue-based intelligent tutoring systems could be designed in a more efficient manner to maximize learning and minimize the cost of time-on-task.

Operation ARA: A computerized learning game that teaches critical thinking and scientific reasoning

Operation ARA (Acquiring Research Acumen) is a computerized learning game that teaches critical thinking and scientific reasoning. It is a valuable learning tool that utilizes principles from the science of learning and serious computer games. Students learn the skills of scientific reasoning by engaging in interactive dialogs with avatars. They are tutored by avatars with tutoring sessions that vary depending on how well students have responded to questions about the material they are learning. Students also play a jeopardy-like game against a feisty avatar to identify flaws in research and then generate their own questions to determine the quality of different types of research. The research examples are taken from psychology, biology, and chemistry to help students transfer the thinking skills across domains of knowledge. Early results show encouraging learning gains.
