The purpose of my video is to give people a better understanding of what goes into building custom mechanical keyboards and provide knowledge for beginners to start their first build. To create my improved video, I used ChatGPT to help generate a barebones script and edited it to fit the needs of my video. I used Canva to design the slides and used Open Broadcast Software (OBS) to record the screencast for my video. DaVinci Resolve was also used to compile and edit the video. The different design principles and theories I learned throughout the term allowed me to improve on the screencast that I had created at the start of the term and deliver a more effective video.

Mayer’s Principle of Coherence

Using Mayer’s principle of coherence, I improved on my previous video by removing a lot of the unnecessary information on slides while keeping the visuals simplistic and related to the topic. Eliminating unnecessary information helps to reduce cognitive overload and promote learning.

Mayer’s Principle of Redundancy

Another thing that I noticed after viewing my previous video was that it contained lots of redundant information. An example of this was some of the previous slides were comprised only of text which I read directly from. Removing the text and adding various graphics and videos while narrating helped to improve my video by promoting learning according to the redundancy principle. The principle suggests that people learn more effectively from graphics and narration or graphics and text than they do from the combination of graphics, narration and text. 

Mayer’s Principle of Modality

The greatest improvement in my video utilizes the modality principle, which states that people learn better from visuals and spoken words rather than visuals and printed words. For this reason, none of my slides contain long written sentences and only uses words for titles. This allows me to narrate over each slide and rely on the graphics and videos to provide a visual representation and connection to my narration. While rewatching the two videos, the improved video felt significantly easier to follow and retain information from.

Subtitles

Uploading the video to YouTube allows the user to take advantage of YouTube’s AI subtitling, which can detect and auto-write subtitles after inputting a language of choice. Subtitles are a good way to add accessibility for learners who need additional visual components when learning.
