Q: Of all the principles of Cognitive Theory of Multimedia Learning we looked at in this module, which seem most intuitive to you? Which ones surprised you?

A: The most intuitive principle to me is the Segmenting Principle. Breaking complex information into smaller, manageable parts aligns naturally with how we process and understand new information. It’s a fundamental approach in teaching complex subjects like cryptography.

The surprising principle is the Personalization Principle. The impact of conversational language in enhancing learning, as opposed to formal speech, highlights the subtle yet significant role of language tone in educational contexts. It’s intriguing how this approach can make complex topics more accessible and relatable.

Q: Which principles did you have in mind when you were creating your screencast? Which were you able to employ and which were more challenging to follow?

A: When creating the screencast on the One Time Pad in cryptography, I primarily had the Segmenting and Coherence Principles in mind. Segmenting was employed by breaking down the cryptographic method into step-by-step segments, making it easier to follow. Coherence was ensured by focusing only on relevant information, avoiding any unrelated content.

The challenging principle to follow was the Modality Principle, given the handwritten, step-by-step nature of the presentation. Balancing the use of text and visuals without narration was a consideration, as it involved deciding how best to communicate complex information clearly and effectively.

Q: Who did you imagine as the audience for this screencast? How did that impact your design choices?

A: I imagined the audience for the screencast as students or enthusiasts with a basic understanding of cryptography but new to the concept of the One Time Pad. This influenced the design choices by emphasizing clarity and simplicity. The step-by-step handwritten method was chosen to mimic a classroom-style teaching approach, allowing viewers to follow along at a pace similar to a traditional learning environment. This approach also considered the learners’ need to grasp foundational concepts before diving into more complex aspects, aligning with the Segmenting Principle for gradual and effective learning.

Q: Provide an example of a multimedia learning principle that you have intuitively followed in the past, and an example of a multimedia learning principle that you have not followed in the past. What will you do differently now?

A: In the past, I have intuitively followed the Coherence Principle. For instance, in presentations, I’ve focused on including only relevant information, avoiding extraneous details or graphics that don’t contribute directly to the learning objective. This approach helps maintain the learner’s focus on the key concepts.

A principle I haven’t always followed is the Redundancy Principle. In some instances, I’ve combined narration, text, and visuals, potentially overloading the learner with repetitive information across different formats.

Moving forward, I will be more mindful of the Redundancy Principle. I’ll aim to balance the use of text, visuals, and narration more effectively, considering the cognitive load and ensuring that each element contributes uniquely to the learning experience without unnecessary repetition.
