文章使用Tobii EyeX眼动仪实时记录在线测评环境下学习者答题的眼动行为数据,对涉及的17种眼动指标进行数据分析,探索了学习者在测试时的视觉注意模式和眼动行为轨迹特点.通过针对浙江工业大学20名硕士研究生的眼动实验,文章发现:在线测试中,题目类型和难度都会影响被试的视觉注意,且题目类型的影响更大;不同组别被试的视觉注意模式存在差异;在不同类型的题目中,被试的视觉注意力分配存在差异.研究在线测评中学习者的眼动行为,有助于预测学习者的答题情况,并为未来多模态生物数据表征研究提供参考.%In this paper, the Tobii EyeX eye tracker was used to record the real-time eye movement behavior data of learners' answers in the online testing environment, and further the concerned 17 kinds of eye movement indexs were analyzed to explore the learners' visual attention pattern and the characteristics of eye movement track. Through the eye movement experiment of twenty postgraduate students in Zhejiang University of Technology, it was found that the type and difficulty of questions affected the participants' visual attention, and the influence of the type of questions on participants' visual attention was greater. Meanwhile, there was difference in the visual attention pattern for different groups of participants. In addition, there was difference in the distribution of visual attention for different types of question. Researching on the learners' eye movement behavior in online testing was conducive to predicting students' answer performances and providing reference for the furture characterization study of multimodality biological data.
