In this assignment, I select to improved my Google Earth story.

Link to my Google Earth story.

I add few things to the Google Earth story. First, I add a link about the Great Wall in the slide. There are lots of information about the Great Wall. I add the landmark of the ticket office on the map. And select the best view in Google Earth. Also, I improved the route of the Great Wall on the map. Based on my understanding of the multimedia principle, I think my origin story is too simple and there isn’t much information about the Great Wall. Therefore, based on the Dual Coding theory, multimedia principle, and coherence principle, I add the photo and the website to make the story be more interesting. The website could let people know more about the Great Wall. Also, the landmark and the photo of the ticket office follow the signaling principle. The viewer could find it easily when they go to the Great Wall. Therefore, I think my update is effective.
