网络学习环境中不同媒体的效果比较研究

A Comparative Study on Learning ─ Effect of Text and Video in E─learning Environment

本文通过对比实验，研究网络学习环境中教学信息媒体呈现方式对学习效果的影响。研究结果显示，以文本形式呈现教学信息以网络视频呈现教学信息在学习效果整体上并没有显著差异，但文本形式更容易在学习目标的”理解”层次上获得较好的学习效果，据此可以推断教学信息媒体呈现方式这一因素在基于网络的学习中对学习效果的影响与教学目标有一定的对应性。

Through contrast experiment， the researchers studies the effect of different mode of information presenting on learning─effect in the e─learning environment. The result showed that no distinct difference on learning─effect between text and video， but text can obtain better learning─effect on understanding of learning objective. It shows that presenting model of information presenting has some parallelism on the impact of learning effect and instructional objective in e─learning environment.
