Finally found a single actual screenshot of the DARPA Digital Tutor (sort of—a later commercial adaptation). Crazy-making that there were zero figures in any of the papers about its design, and not enough details to imagine one.
Some observations: * An instructional interface is presented alongside a live machine. * Student presented with a concrete task to achieve in the live system. * The training system begins by “discussing the situation”, probing the student’s understanding with q’s, and responding with appropriate feedback and follow-up tasks. * It can observe the student’s actions in the live system and respond appropriately. * The instructional interface uses a text-conversational modality. * I see strong influence from Graesser’s AutoTutor, and some from Anderson’s Cognitive Tutors.
