Based on the lecture that the article “Storytelling: Bringing the power of stories to your teaching”, the author explains how to interact and efficiently tell the story. Video narrative could be more effective in encouraging students to backup the files on the laptops because it helps the narrator to remember what is going on in that story. The picture helping the narrator to trigger the stimuli and active the “mirror neuron” to make a flashback. The narrator could act as an audience to test his memory. However, the only problem is the file might be too big to save compared to audio. Audio is easier to save in different place no matter is a hard drive or backup app. But every time the narrator listens to his own story will create a different image out of the story, so it could make to a different understanding when he wants to create the story again.
Video narrative has its advantage so I do not want to judge about the less effective or more effective question. Individual difference creates a different preference norm, so depends on people’s learning style people might choose audio-only for less distraction. More pictures not only help to understand the story but also can lock people’s imagination into that “box”.
The two version narratives both highlight the segmenting principle which does give the audience option to pause the video/audio and go with their speed. Also, the personalized principle did raise the engagement on both forms because the professor using a slow and casual voice to describe the story. Our professor did use the redundancy principle in the video narrative to give a direct understanding by using pictures while he is talking. Overall, for education purpose teacher may combine both narratives to improve the quality.
