文字强调方式对多媒体学习的影响——基于眼动追踪技术

摘要

To analyze and evaluate the effect of different emphasis on multimedia texts with the advanced eye-tracking technolo-gy.The emphasis methods of bold script(3×2)with different colors as the experiment group and the emphasis methods of characters that were not bold with black color as the control group were put forward in order to make the experiment design.From three eye-movement indicators of total times of gaze,the length of reading time,the length of the time when the sight stayed on the interest-are-a,the learners′cognitive processing was researched and analyzed.The effect of learning with emphasized script is apparently better than that with non emphasis,and the bold script with blue color is significantly easier to understand than other ways and is the most suitable way to emphasize texts in reading materials.%利用眼动追踪技术,从生理和心理两方面对多媒体文本中不同的字体强调方式的学习效果进行客观的分析和评价.以不同字体颜色和加粗(3×2)的字体强调方式作为实验组,以黑色不加粗的字体作为对照组来进行实验设计,从总注视次数、阅读时间、目标区停留时间3个眼动指标对学习者认知加工过程研究分析,得出了以下结论:有字体强调的学习效果明显优于没有字体强调;在被研究的5种强调方式中,蓝色加粗的字体强调方式下的阅读效果最佳.
