This week I learned how to take screenshots and create multimedia content.
First of all, I know Five Principles for Reducing Extraneous Processing. They are the Coherence Principle, Signaling Principle, Redundancy Principle, Spatial Contiguity Principle, and Temporal Contiguity Principle. Next, I learned about Three Principles for Managing Essential Processing. These three principles include Segmenting Principle, Pretraining Principle, and Modality Principle. These principles are helpful for how to take screenshots to create multimedia content. I thought about these principles when I took the video, and I tried to abide by these principles as much as possible.
When I watched youtube videos, I found that some of the edited videos were not very long, and the extra content was deleted while editing, which made the theme of the video stand out and saved the viewer’s time. I also found that if editors combine two videos together, there will often be transition effects, which makes the video look very coherent. I think Coherence Principle, Coherence Principle, and Segmenting Principle are suitable for PowerPoint presentations in classrooms or face-to-face business meetings. In the PowerPoint presentation, the speaker needs to highlight his topic, and according to the Coherence Principle, irrelevant materials should be excluded. According to the signal principle, some keywords can appear in PowerPoint, these words can let the audience directly understand the content, can also remind the speaker, let the speaker continue to speak. According to the Segmenting Principle, PowerPoint is divided into several parts and presented to the audience separately.
