I made a video using my iPad and the built-in screen recording feature to show how to convert decimal (base-10) numbers to binary (base-2) and how to change binary numbers back to decimal. These conversions are important in computer science because computers use binary to work. In this post, I’ll explain how I applied some important principles from Mayer’s Cognitive Theory of Multimedia Learning to make the video clear and easy to understand.
Multimedia Learning Principles
When I created the video, I focused on making sure it wasn’t too confusing or overloaded with information. I also worked on helping viewers understand the topic in a simple way.
Redundancy Principle: I didn’t show both text and narration at the same time. Instead, I used my iPad to draw out the steps and explain them while I was drawing. This helped keep the video clear and kept the focus on the important information.
Segmenting Principle: I broke the process into small, easy-to-follow steps. First, I explained what binary is and why it’s important. Then, I showed how to convert a decimal number into binary, followed by how to change a binary number back into decimal. This allowed learners to take in the information one step at a time.
Pre-training Principle: Before getting into the conversion process, I explained basic terms like “binary,” “decimal,” and “base system.” This helped prepare the learners so they wouldn’t be confused by new terms during the video.
Audience Consideration
I imagined my audience to be beginners, such as students learning about number systems for the first time. Because of this, I kept my explanations simple and used lots of visual examples. I wanted the video to be easy to follow without diving too deep into technical details.
Conclusion
Using my iPad and Apple’s screen recording feature, I created a video that followed important multimedia learning principles. This experience taught me a lot about how to create learning materials that are easy to understand and avoid overwhelming the viewer. I hope this video will help learners new to binary and decimal conversions.
I love how you visually explained the steps while narrating—it made everything clear and easy to follow. Your use of the redundancy and segmenting principles really stood out to me. Breaking everything into simple steps was super helpful for beginners. It’s also smart that you included pre-training to explain key terms before diving into the conversions. Overall, your approach made topic like binary conversions feel much more approachable. Great job!
