This research will explore interactions between cognition and emotion during the learning of scientific methods in the context of a computer tutoring environment. The primary focus will be on the relations between impasses, cognitive disequilibrium, and the affective-cognitive state of confusion. Confusion correlates with learning gains because it is diagnostic of cognitive disequilibrium, a state that occurs when learners face obstacles to goals, contradictions, incongruities, anomalies, conflicts, and system breakdowns. Cognitive equilibrium is normally restored after thought, reflection, problem solving and other effortful cognitive activities. Therefore, pedagogical tactics that challenge, perplex, and productively confuse learners are stimulating alternatives to the typical information delivery systems in education that promote shallow knowledge in the comfort zone of the learner, but rarely deep comprehension. This research will develop tutorial interventions that induce, track, and regulate confusion and cognitive disequilibrium in the minds of learners, as well as the cognitive and emotional mechanisms that restore cognitive equilibrium. The research has three specific objectives: (1) To promote deep learning by developing tutorial interventions that experimentally induce impasses, cognitive disequilibrium, and the resulting confusion; (2) to integrate sensing devices and signal processing algorithms that detect and track the associated confusion; and (3) to develop affect-sensitive pedagogical strategies to help learners regulate their confusion. The three objectives will be accomplished by augmenting an existing Intelligent Tutoring System (ARIES, Acquiring Research Investigative and Evaluative Skills) with technologies that automate assessment of emotion and cognition, as well as an intelligent handling of emotions. State-of-the-art sensing devices detect relevant emotions during learning (confusion, frustration, boredom, flow/engagement, delight, surprise) on the basis of the dialogue history, facial expressions, and body posture. The ARIES system promotes scientific inquiry skills by presenting case studies that exhibit flawed scientific methods and that require learners to offer thoughtful critiques on the scientific merits of the studies. The critiques encourage (a) the general cognitive processes of drawing inferences, constructing causal models, identifying problems, and asking diagnostic questions and (b) skills that directly target scientific reasoning, such as stating hypotheses, identifying dependent and independent variables, isolating potential confounds in designs, interpreting trends in data, and determining whether data support predictions. Students interact with ARIES through conversational trialogues in natural language with two animated agents: a tutor agent and a peer agent. Cognitive disequilibrium is created when the agents produce messages with contradictions, conflicts, and clashes with what the student knows. Correct information eventually emerges in the trialogue, which restores cognitive equilibrium. The broader significance and importance of the project is to advance science education, intelligent learning environments, and human-computer interfaces. It is widely acknowledged that the level of science understanding among students and adults in the United States needs improvement and does not compare favorably with several other nations. The proposed research will help fill this gap by developing technological interventions to fortify citizens and aspiring scientists with the skills needed for critical thinking, complex reasoning, and problem solving in science. The project will develop intelligent learning environments targeted for deeper learning, which is needed for a technologically sophisticated workforce, and for a motivating learning experience, which is expected in recent generations of students. The project will develop advanced sensing devices for detecting emotions and cognition, a contribution that should impact the fields of human-computer interaction, cognitive science, and the learning sciences.

本研究将在电脑教学环境中探讨科学方法学习过程中认知与情绪之间的互动关系。主要的焦点将集中在僵局、认知失衡和混乱的情感-认知状态之间的关系。困惑与学习收益相关，因为它是认知失衡的诊断，认知失衡是当学习者面临目标障碍、矛盾、不协调、异常、冲突和系统崩溃时发生的一种状态。在思考、反思、解决问题和其他费力的认知活动后，认知平衡通常会恢复。因此，挑战、困惑和富有成效地迷惑学生的教学策略正在刺激教育中典型的信息传递系统的替代方案，这些系统在学习者的舒适区推广肤浅的知识，但很少有深度理解。这项研究将开发辅导干预措施，诱导、跟踪和调节学习者头脑中的困惑和认知失衡，以及恢复认知平衡的认知和情感机制。这项研究有三个具体目标：(1)通过开发实验上导致僵局、认知失衡和由此产生的困惑的辅导干预措施来促进深度学习；(2)整合检测和跟踪相关困惑的传感设备和信号处理算法；(3)开发对情感敏感的教学策略，帮助学习者调节他们的困惑。这三个目标将通过使用自动化情绪和认知评估以及智能情绪处理的技术来增强现有的智能辅导系统(白羊座，获取研究、调查和评估技能)来实现。最先进的传感设备根据对话历史、面部表情和身体姿势检测学习过程中的相关情绪(困惑、沮丧、无聊、心流/投入、喜悦、惊讶)。白羊座系统通过展示有缺陷的科学方法的案例研究来促进科学探究技能，这些案例研究要求学习者对研究的科学价值提出深思熟虑的批评。这些评论鼓励(A)推理、构建因果模型、识别问题和提出诊断性问题的一般认知过程，以及(B)直接针对科学推理的技能，如陈述假设、识别因变量和自变量、隔离设计中的潜在混淆、解释数据趋势，以及确定数据是否支持预测。学生通过自然语言对话与白羊座互动，有两个动画代理：辅导代理和同行代理。当代理产生的信息与学生所知道的存在矛盾、冲突和冲突时，就会造成认知不平衡。正确的信息最终会出现在三段式中，这会恢复认知平衡。该项目更广泛的意义和重要性是推进科学教育、智能学习环境和人机界面。人们普遍认为，美国学生和成年人的科学理解水平有待提高，无法与其他几个国家相提并论。拟议的研究将通过开发技术干预措施来帮助填补这一空白，以增强公民和有抱负的科学家的批判性思维、复杂推理和解决科学问题所需的技能。该项目将开发智能学习环境，旨在进行更深入的学习，这是一支技术先进的劳动力所需要的，也是为了获得激励学习体验的，这是近几代学生预期的。该项目将开发用于检测情绪和认知的先进传感设备，这一贡献将影响人机交互、认知科学和学习科学领域。
