Screencasting
Dual Coding Theory states that there are two channels in our brain to take in information. Eyes and ears are working together to take in knowledge in the form of texts and pictures. The brain processes the information and integrates them with the prior knowledge in long-term memory. Screencasting involves the recording of the demonstration on the computer screen and voice-over while performing the demonstration. While a learner watching a screencast, he or she is able to take in verbal information and visual content at the same time. Use screencasting in multimedia learning is aligned with the dual coding theory since it transfers knowledge through both visual and audio content.
Screencasting is widely used during the pandemic since online learning is more preferred than the face-to-face method of teaching. Teachers and professors use screencasting to demonstrate a specific technique or teaching new knowledge to the students. Some professors screencast their synchronize online class as the students may prefer to rewatch it, and some professors upload screencast videos for the student to watch at their own time. In my opinion, screencasting is also useful for the open learning environment, since learners can learn new skills whenever they have time. The following screencast video I created is about the process of installing and using the “Honey” extension in the browser. I tried to minimize the distraction by not using background music and close non-related tabs in the browser. Hope the screencast I created is easy to follow and demonstrates the required steps.

Hello Anna,
I really like your detailed introduction to screencasting and its connection with the Dual Coding Theory. Screencasting is definitely a great example of how our sense of hearing and seeing are combined to maximize our learning outcomes. It is widely used not only in academic settings, but also in business or professional fields to transfer information, and can often deliver good results. I love your demonstration on how to use Honey, the Chrome extension that is designed to seek to automatically find coupon codes. The detailed narration and steps are really understandable and easy to follow. Although the validity of its coupons is testable, this is a nice-to-have extension in case something useful shows up.
Cheers,
Liyao Ma

Hey Anna! Wonderful perspective on screencasting. I agree that screencasting is an important avenue to support the dual coding theory and allows many people, who have schedules, to get in some extra learning on their own time. Screencasting is a great way to share ones knowledge on their digital platform (which everyone is on nowadays). It can benefit students, teachers, parents, and any other professionals that want to learn at their own pace (rewinding videos is super helpful) Also, nice video about installing Honey, it’s funny to see how many Youtubers advertise that Google Chrome Extension.
