Blog#4 screencasting in education

• List some possibilities you see for digital story telling or screencasting in education

In the past, I had no experience with using screencasting in my studies. However, because of COVID-19 in the past year and a half, the school had to change the course to an online course, so I had the opportunity to be exposed to the experience of teaching through screencasting. Because of the epidemic, there are certain disadvantages to teaching online, students cannot communicate directly with the teacher, and there are many assignments that students may not understand how to deal with, so there will be problems so if you go to the teacher in this case, you can only go through the mail, and it usually takes at least two to three days to get a response from the teacher, so to avoid delays and In order to avoid delays and the inability to get a timely response when too many students do not understand, some teachers choose to do video teaching through screencasting. For example, I chose Economics 381 this semester. All the assignments in this class need to be completed through software called R. When I was in this class, I was the first to use R. The most challenging part of it compared to other software is that you need to download and install it yourself. After installation, you need to download and apply the materials prepared by the teacher before you can start completing the assignments. So this process was challenging for the students who first encountered the software R. Therefore, in the first week, many students contacted the teacher to ask how to do it. Hence, the teacher provided the correct way to use R through screencasting, which included the steps to download the material package, which I think was very convenient and helped the students solve their problems. Here is an example of how I used the instructor’s screencasting, which I also recorded through screencasting.

• Which multimedia learning principles would apply to a PowerPoint presentation in a classroom or face-to-face business meeting?

In the Powerpoint presentation process, I think the multimedia learning principles that can be applied to the inside are the most important is the signal principle. Whether we are in the process of classes or face-to-face business meetings when using Powerpoint to explain, the content inside is the most important. If the Powerpoint process adds much complex theoretical knowledge and contains an enormous paragraph of text, watching the video presentation will feel too much content, unable to understand what you want to express. So this time, the signal principle is fundamental because if the important words are highlighted, people can quickly grasp the focus and understand what they need to learn so that they will learn better. On the other hand, if animation is added during the presentation, it will make the content of the presentation more vivid, and if the principle of temporal coherence is also met, it can also make us learn better because when the video or animation is played, and the corresponding narration is added at the same time, the content of the video can be better understood, thus achieving a better learning effect.
