冗余信息对多媒体学习的影响研究

The Effect of Redundant Information on Multimedia Learning

为考察冗余信息的性质与媒体类型对多媒体学习效果的影响,实验采用3(信息的性质)×3(信息的媒体类型)两因素实验设计,以"应激反应的生理机制"为学习材料对210名大学生进行了研究。结果显示,冗余信息的性质与媒体类型对多媒体学习的回忆成绩没有显著影响,对迁移成绩有显著影响;冗余信息的性质与媒体类型对多媒体学习的回忆成绩有交互影响,对迁移成绩没有交互影响。

In order to investigate the effect of redundant information nature and media type on multimedia learning, 210 college students were chosen and radomly assigned to seven groups and learned different multimedia materials about physiological mechanism of stress response. The results showed that the nature and media type of redundant information didn＇t significantly affect recall scores, but obviously affect transfer scores, and there was an interactive effect of the redundant information nature and media type on recall scores, but no on transfer scores.
