Prompt: 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?
I think the most intuitive and one that I fully agree with is the Signaling Principle. Highlighting or labeling important details allows learners to locate the key points more quickly and to deepen their memory of the key points. Highlighting important details also allows us to reduce extraneous load by minimizing attention to other, less important parts.
I agree with all the principles mentioned in module 1, and I am not surprised by any of them. But it was Allan Pavio’s Dual Coding Theory, which states that there are two separate channels in our memory for receiving new things, one visual and one verbal, that opened my eyes. After reading this definition, I felt that it was very obvious and easy to see, but when I thought about it, I did not have any idea about it before. For example, I used to think that listening and viewing were actually done together, that they shared the same channel, because in many cases I could not handle the narration I was hearing and the text on the screen very well on my own. But after studying module 1, I understand that this is the same redundancy mentioned in this unit.
Prompt: Who did you imagine as the audience for this screencast? How did that impact your design choices?
My screencast videos are designed for people who have never worked with digital signals or digital circuits. That’s why I used a blackboard. Starting from empty and adding content to the board step by step with the narration. To avoid most of extraneous loads due to redundancy or unnecessary contents.

I used my tablet’s video recording function to record. I also used Samsung Notes software as a blackboard to write on. In this video I talk about basic digital circuits and try to give the learner a basic understanding of digital circuits. In this video I try to use the Coherence Principle, the Signaling Principle and the Voice Principle. Here is my video.
