I’m going to introduce my multimedia project. My multimedia project is a video teaching about an algorithm. This video is about decision trees. The purpose of this video is to give students who are interested in algorithms a basic understanding of decision trees. After this short video course, students will learn about decision tree definitions and how to use decision trees to solve problems.
This is the original video.

I’ve learned after watching the original video many times that my multimedia projects fall short. I also made some improvements at the same time, but I found that because the video was too old, I couldn’t make a perfect edit. However, it’s like a teacher who will teach tomorrow and he has an existing instructional video. What he can do now is to make video lessons even better because of multimedia learning principles and related learning theories.

Now let’s take a closer look at video teaching. First, instructional videos are media. Teaching video is a teacher outputting knowledge content in the video content, and students can only passively receive knowledge. So, I wanted to modify the video a little so that there are pauses in the short video. My solution was to turn the media into interactive multimedia. Adding some interesting real-world problems to the video allows students to understand the use of the knowledge of decision trees. Knowing Practice and Application may be overlooked when teachers teach(2022). This is actually the same as Jennifer Gonzalez. As she said in her article, I want to guide students to practice this knowledge point. I also have students apply this knowledge point at the same time. Based on Merrill’s Principles of Instruction, learning is facilitated as students solve real-world problems (2019).

Secondly, I found that when making the video, in order to make the video not very boring, I added background music. But when recording video, my voice is not very clear. So I don’t think my video meets the inclusive design. Captions help some people have a better experience (Sehl, 2020). I can’t find the original video, but I uploaded it to youtube. So, I used youtube automatic subtitles and re-recorded it. I also added some video instructions, so that students who already know the knowledge can avoid repeated learning.
