中文摘要:
      目的 在于分析不同微课视频文本设计策略对学习者视觉注意的影响。方法 采用对比实验法,采集学习者观看微课视频文本时的注视路径、注视热点、注视时间、注视次数等眼动数据,以之表征视觉注意,对比分析学习者对采用不同设计策略的说明性文本、字幕不同区域、不同词性字幕词汇的视觉注意差异。结果 得出学习者对复色重点文本的注意时间与注意次数明显高于单色重点文本,且存在极其显著差异,复色文本设计策略能有效提高学习者对重点文本信息的视觉注意。学习者对字幕不同区域的视觉注意存在差异,每行字幕从左到右20%~30%、40%~80%为学习者高视觉注意区。学习者对字幕中名词、动词、数词的视觉注意高,但不同词性的视觉注意不存在显著差异。
英文摘要:
      The work aims to analyze the impact of different micro-lecture video text design strategies on learners’ visual attention. Through comparative experiment, the eye tracking data of learner’s gaze path, heat maps, time spent, ratio, etc. for micro-lecture video text were collected to characterize the visual attention. Then, the difference of learners’ visual attention in explanatory texts, different regions of subtitles, and different word nature of subtitles was analyzed. The study showed that the time spent and ratio of learners’ attention to multicolored explanatory texts were obviously higher than those of monochrome explanatory texts, and there were extremely significant differences. Multicolored text design strategy could effectively improve learners’ visual attention to explanatory text information. Learners’ visual attention was various in different areas of subtitles. From left to right, the 20%~30% and 40%~80% area of subtitles were high visual attention area. Learners have a high degree of visual attention on nouns, verbs, and numerals in the subtitles, but there is no significant difference between the nature of different words.
