Abstract
Communication is a core component of collaborative problem solving and its assessment. Advances in computational linguistics and discourse science have made it possible to analyze conversation on multiple levels of language and discourse in different educational settings. Most of these advances have focused on tutoring contexts in which a student and a tutor collaboratively solve problems, but there has also been some progress in analyzing conversations in small groups. Naturalistic patterns of collaboration in one-on-one tutoring and in small groups have also been compared with theoretically ideal patterns. Conversation-based assessment is currently being applied to measure various competencies, such as literacy, mathematics, science, reasoning, and collaborative problem solving. One conversation-based assessment approach is to design computerized conversational agents that interact with the human in natural language. This chapter reports research that uses one or more agents to assess human competencies while the humans and agents collaboratively solve problems or answer difficult questions. AutoTutor holds a collaborative dialogue in natural language and concurrently assesses student performance. The agent converses through a variety of dialogue moves: questions, short feedback, pumps for information, hints, prompts for specific words, corrections, assertions, summaries, and requests for summaries. Trialogues are conversations between the human and two computer agents that play different roles (e.g., peer, tutor, expert). Trialogues are being applied in both training and assessment contexts on particular skills and competencies. Agents are currently being developed at Educational Testing Service for assessments of individuals on various competencies, including the Programme for International Student Assessment 2015 assessment of collaborative problem solving.
