Presentation skills are necessary for any professional, but they are more important for educators. The audience will have a much better learning experience if the presenter can design and produce powerful PowerPoint slides to accompany the presentation.
In the core multimedia skills assignment, I choose to update one of the PowerPoint presentations I made for another class. I will use Prezi to reflect my current understanding of multimedia learning principles. Prezi is a kind of presentation software that makes ideas more interesting mainly through zooming and shortcut actions. It broke the traditional PowerPoint single-line sequence, using systematic and structural integration of the way to demonstrate, with the route of presentation, from an object suddenly pulled to another object, with rotation and other actions being more visual impact.
In this project, I want to demonstrate how the design thinking methodology can be used to produce multimedia and interactive learning materials. I will also identify and discuss the principles of good interaction design.
The original slides were based on the essay, I did not make too much effort, just selecting the contents and reading the paragraphs straight. In the updated version, I make significant modifications to both the content and the layout.

Here are some important adjustments and principles based on:
| Key Changes | Multimedia learning theory/principle |
| Remain only 1 idea per slide | Cognitive load theory |
| No more than 6 objects per slide | Cognitive load theory |
| Don’t read the text of the slide, and remove the draft below | Redundancy principle |
| Use an illustrative image and short text on a slide (add images and videos), and then tell the rest of my story via narration | Multimedia and modality principles |
| Use contrast to move your audience around the information | Signalling and coherence principles |
There are also other components of the original slides that I do not enhance because I believe they are already effective based on multimedia learning principles and related learning theories.
| Remain Unchanged | Multimedia learning theory/principle |
| Maintain each slide’s subheadings | Segmenting and coherence principles |
| Make sure the most important thing is the most prominent | Signalling principle |
Overall, the information and knowledge I intend to deliver should be transferred more efficiently owing to my updated and enhanced presentation, which is based on the mentioned principles and theories of multimedia learning.
